Hudbay Announces First Quarter 2021 Results

Toronto, Ontario, May 11, 2021 - Hudbay Minerals Inc. ("Hudbay" or the "company") (TSX, NYSE:HBM) today released its first quarter 2021 financial results. All amounts are in U.S. dollars, unless otherwise noted.

First Quarter Operating and Financial Results

• Consolidated copper production in the first quarter was 24,553 tonnes at cash cost and sustaining cash cost^i^ per pound of copper produced, net of by-product credits, of $1.04 and $2.16, respectively. Consolidated gold production in the first quarter was 35,500 ounces, a record for Hudbay.
• Full year 2021 production and operating cost guidance reaffirmed; Pampacancha production commenced in April 2021, in line with guidance.
• First quarter Manitoba copper production significantly increased from 2020 levels primarily due to higher grades at 777 and higher recoveries at the Flin Flon concentrator; sales volumes were impacted by the availability of railcars during the quarter with 5,000 tonnes of copper concentrate inventory in excess of normal operating levels, valued at approximately $18 million.
• First quarter Peru sales impacted by a 10,000 tonne shipment of copper concentrate, valued at approximately $21 million, for which a payment was received but not recorded as revenue due to the timing of the shipment being delayed to early April. Peru's production in the first quarter was impacted by increased ore hardness as well as a semi-annual scheduled plant shutdown in January.
• First quarter net loss and loss per share were $60.1 million and $0.23, respectively. After adjusting for one-time financing charges mainly related to the redemption of the 2025 senior notes and a revaluation of the gold prepayment liability, first quarter adjusted net loss per share^i^ was $0.06. First quarter adjusted EBITDA^i^ was $104.2 million.
• Operating cash flow before change in non-cash working capital increased to $90.7 million in the first quarter of 2021, from $86.1 million in the fourth quarter of 2020 due to higher realized metal prices, offset by lower sales volumes.
• Cash and cash equivalents decreased during the first quarter to $310.6 million, as at March 31, 2021, mainly as a result of $83.0 million of capital investments primarily for the New Britannia project and Pampacancha development activities, $50.8 million of interest payments and $31.0 million in net transaction and early redemption costs related to the refinancing of the company's 2025 notes, partially offset by cash generated from operations.

Executing on Growth Initiatives

• Announced three-year production guidance; consolidated copper and gold production are expected to increase by 36% and 125%^ii^, respectively, by 2023 from 2020 levels as the company brings the Pampacancha and New Britannia growth projects into production.

• Finalized the remaining land user agreement for Pampacancha in early April 2021. This provided Hudbay with full access to the site to complete pit development and commence first ore production in late April, in line with timelines assumed in the company's updated mine plan. Total 2021 growth capital guidance for Peru has increased to $25 million to include the final land user costs.

TSX, NYSE - HBM<br><br> <br>2021 No. 12

• New Britannia project continues to track ahead of the original schedule and is nearing completion, with approximately 82% of the project completed at the end of April; first gold production continues to be expected early in the third quarter and the new copper flotation facility remains on track for commissioning and ramp-up in the fourth quarter of 2021.

• Announced a year-over-year increase to total mineral reserves of approximately 170,000 tonnes of contained copper and 360,000 ounces of contained gold, after adjusting for 2020 mining depletion.

• Announced an updated Constancia mine plan resulting in an increase in average annual copper production to approximately 102,000 tonnes over the next eight years at an average cash cost of $1.18 per pound of copper produced, net of by-product credits.

• Announced an updated Lalor and Snow Lake mine plan resulting in an increase in annual gold production to over 180,000 ounces during the first six years of New Britannia's operation at an average cash cost of $412 per ounce of gold produced, net of by-product credits.

• Announced a significant new discovery at the company's Copper World properties adjacent to Rosemont on wholly-owned private land. Four deposits have been identified to date with a combined strike length of over five kilometres consisting of high-grade copper sulphide and oxide mineralization at shallow depth. The follow-up 2021 exploration program has been expanded to further test the potential for additional mineralization, develop an initial inferred resource estimate and complete a preliminary economic assessment. As a result, Hudbay has increased its 2021 spending on Copper World by approximately $24 million.

• Announced a preliminary economic assessment ("PEA") for the Mason copper project with a 27-year mine life and average annual copper production of approximately 140,000 tonnes over the first ten years of full production. The PEA indicates an after-tax net present value^iii^ of $519 million and approximately 14% internal rate of return at $3.10 per pound copper, which increases to $773 million and approximately 15%, respectively, at $3.25 per pound copper.

• Issued $600.0 million of 4.5% senior notes due 2026 and redeemed all of the company's outstanding $600.0 million of 7.625% senior notes due 2025, thereby reducing its annual cash interest payments.

• On May 10, 2021, an amendment to the Constancia streaming agreement was signed with Wheaton Precious Metals ("Wheaton"). The amendment eliminates the requirement to deliver an additional 8,020 ounces of gold to Wheaton for not mining four million tonnes of ore from the Pampacancha deposit by June 30, 2021, while increasing the fixed gold recovery applied to Constancia ore processed during the reserve life of Pampacancha and introduces an additional potential future deposit of $4 million from Wheaton.

"Our operations remain on track to achieve full year production and unit cost guidance following a strong quarter of production at the Manitoba business unit and lower first quarter production in Peru as a result of planned mill maintenance," said Peter Kukielski, President and Chief Executive Officer. "We are very pleased to have commenced production at Pampacancha and we look forward to our first gold pour at the New Britannia mill, which remains on schedule for the third quarter. We expect to begin to see increased cash flows from these high-return investments in the second half of 2021. We also expect to significantly advance our longer-term copper growth opportunities this year, including the Rosemont, Copper World and Mason projects. We believe we will continue to leverage our exploration and development expertise to create significant value from our attractive organic growth pipeline at Hudbay."

TSX, NYSE - HBM<br><br> <br>2021 No. 12

Summary of First Quarter Results

Consolidated copper production in the first quarter of 2021 was 24,553 tonnes, a 10% decrease from the fourth quarter of 2020, primarily as a result of lower mill throughput at Constancia due to a scheduled semi-annual mill maintenance shutdown, partially offset by higher copper grades at 777 and higher copper recoveries at the Flin Flon mill. Consolidated gold production increased by 10% compared to the fourth quarter of 2020 due to higher gold grades at 777, higher gold recoveries at the Flin Flon concentrator and higher gold grades at Constancia. Consolidated zinc production in the first quarter was 8% higher than the fourth quarter of 2020 due to higher zinc grades and throughput.

In the first quarter of 2021, consolidated cash cost per pound of copper produced, net of by-product credits^i^, was $1.04, an increase compared to $0.43 in the fourth quarter due to lower copper production, higher operating costs and lower by-product credits. Incorporating cash sustaining capital, royalties, selling, administrative and regional costs, consolidated all-in sustaining cash cost per pound of copper produced, net of by-product credits^i^, in the first quarter of 2021 was $2.37, which increased from $2.24 in the fourth quarter due to the same factors impacting cash costs, partially offset by lower cash sustaining capital.

Cash generated from operating activities in the first quarter of 2021 decreased to $51.8 million compared to $121.1 million in the fourth quarter of 2020, primarily as a result of changes in non-cash working capital and lower sales volumes. Operating cash flow before change in non-cash working capital was $90.7 million during the first quarter of 2021, reflecting a slight increase from $86.1 million in the fourth quarter. The increase in cash generated from operating activities is primarily the result of higher realized prices, offset by lower sales volumes during the quarter.

Net loss and loss per share in the first quarter of 2021 were $60.1 million and $0.23, respectively, compared to a net earnings and earnings per share of $7.4 million and $0.03, respectively, in the fourth quarter of 2020. First quarter earnings benefited from higher realized prices for all metals, which was offset by lower sales volumes of all metals due to the timing of sales in Peru and a buildup of copper concentrate in Manitoba caused by limited railcar availability. First quarter results included a $12.5 million non-cash gain on the revaluation of the gold prepayment liability but were negatively impacted by charges related to the refinancing of the 2025 senior notes, including a non-cash write off of $49.8 million connected with the exercise of the redemption option, a call premium payment of $22.9 million and a non-cash expense of unamortized transaction costs of $2.5 million in relation to the 2025 notes that were redeemed. A variable consideration adjustment to deferred gold and silver revenue resulted in a net increase to revenue of $1.6 million.

Adjusted net loss^i^ and adjusted net loss per share^i^ in the first quarter of 2021 were $16.1 million and $0.06 per share after adjusting for the finance charges and the net mark-to-market loss on financial instruments, among other items. This compares to an adjusted net loss and adjusted net loss per share of $16.4 million and $0.06 per share in the fourth quarter of 2020. First quarter adjusted EBITDA^i^ was $104.2 million, compared to $106.9 million in the fourth quarter of 2020.

First quarter Peru sales were impacted by a 10,000 tonne shipment of copper concentrate valued at approximately $21 million for which a payment was received but did not meet the revenue recognition criteria due to the delayed timing of the shipment into early April. First quarter Manitoba sales were impacted by a delay in accessing additional railcars after a strong copper production quarter resulting in approximately 5,000 tonnes of copper concentrate inventory in excess of normal operating levels, valued at approximately $18 million. Had both parcels of copper concentrate been sold during the first quarter, the company would have realized approximately $39 million of incremental revenue, assuming end of quarter commodity prices. The above quantities have been recognized as revenue in the second quarter of 2021. First quarter results were also negatively impacted by the realized copper price hedging of the company's provisionally priced copper sales.

^4^ Includes approximately $4.6 million, or $0.72 per tonne, of COVID-related costs during the first quarter of 2021.

The Constancia team continues to effectively operate in an environment of strict COVID-19 measures and controls. This includes working collaboratively with the local health authorities to ensure the company's workforce and partners adhere to COVID-19 protocols while continuing to operate safely and efficiently. Full year production of all metals and unit operating costs at Constancia are on track to achieve the guidance ranges for 2021.

During the quarter, the Constancia operations produced 17,827 tonnes of copper, 4,638 ounces of gold, 405,714 ounces of silver and 294 tonnes of molybdenum. Production was lower than the fourth quarter of 2020 primarily as a result of lower throughput from a scheduled mill maintenance program in the first quarter.

TSX, NYSE - HBM<br><br> <br>2021 No. 12

Ore mined during the first quarter of 2021 was lower than the fourth quarter of 2020 as mining levels were optimized for lower mill throughput while managing the level of contaminants and hardness in the ore sent to the mill. Ore milled during the first quarter of 2021 was lower compared to the fourth quarter of 2020 due to the deferral of a fourth quarter plant maintenance shutdown to January 2021 and increased ore hardness. Milled grades for copper were relatively consistent with fourth quarter levels while milled gold grades were higher as the company accessed high grade ore from the deeper banks of the pit. Recoveries of copper were lower than the previous quarter, but in line with the recently updated Constancia mine plan, and gold and silver recoveries remained consistent with the previous quarter.

Combined mine, mill and G&A unit operating costs in the first quarter of 2021 were $12.46 per tonne, and higher than the fourth quarter of 2020, primarily due to fewer tonnes of ore milled and increased operating costs related to the planned plant maintenance shutdown and enhanced COVID-19 protocols. Excluding COVID-related costs in Peru of $4.6 million, the unit operating costs in the first quarter were $11.74 per tonne. The company expects full year unit operating costs to decline and be in line with the 2021 guidance range.

Peru's cash cost per pound of copper produced, net of by-product credits, in the first quarter of 2021 was $1.82, higher than the previous quarter primarily due to higher milling costs and lower copper production. Peru's sustaining cash cost per pound of copper produced, net of by-product credits, in the first quarter of 2021 improved to $2.36, compared to $2.58 in the prior quarter, due to lower cash sustaining capital spending in the first quarter, partially offset by the same factors affecting cash costs during the quarter.

The Manitoba business unit had stable operating performance across the mines, mills and zinc plant during the first quarter while facing increasing COVID-19 related logistical challenges. Late in 2020, Hudbay added new controls at the Snow Lake camp by introducing point of care PCR testing. Similar testing is being introduced in Flin Flon during the second quarter. COVID-19 vaccinations are currently being rolled out throughout the Snow Lake and Flin Flon communities and workforce. Full year production of all metals and unit operating costs in Manitoba are on track to achieve the guidance ranges for 2021.

Production during the quarter included 27,940 tonnes of zinc, 6,726 tonnes of copper, 30,862 ounces of gold and 290,959 ounces of silver. Production results for all metals were higher than the previous quarter primarily due to higher throughput, head grades and recoveries.

Ore mined at the Manitoba operations during the first quarter of 2021 was higher than the fourth quarter of 2020 due to full production levels at the 777 mine following the shaft repairs that were completed in the fourth quarter. Copper and gold grades at 777 were higher than the fourth quarter as higher grade remnant stopes were mined as 777 nears the end of its mine life.

Development and underground construction activities continue in the lower part of the Lalor mine in order to ensure the company maintains consistent gold and copper-gold production for the start-up and ongoing operation of the New Britannia mill, scheduled for early in the third quarter of 2021. As at the end of the first quarter, approximately 26,000 tonnes of gold ore had been stockpiled as initial feed for the New Britannia mill, up from 12,000 tonnes at the end of the fourth quarter of 2020. The incremental mining activity associated with growing the gold ore stockpile has contributed to elevated combined mine, mill and G&A unit operating costs during the first quarter of 2021. The gold ore stockpile is expected to continue to grow during the second quarter of 2021.

At the Stall concentrator, ore processed during the first quarter of 2021 was only 3% lower than the fourth quarter of 2020, which was a record quarter for Stall, despite the continued stockpiling of Lalor gold ore ahead of the New Britannia mill. Stall recoveries during the first quarter of 2021 were consistent with the metallurgical model. In early April, production at the Stall mill was suspended for four days as a precaution due to COVID related absenteeism. Hudbay does not expect any material impact to second quarter financial results related to the Stall mill production suspension. Ore processed at the Flin Flon concentrator in the first quarter of 2021 increased compared to the previous quarter as a result of the 777 shaft repairs impacting the previous quarter, but were not as high as prior periods as less Lalor ore was processed in Flin Flon in order to grow the gold ore stockpile as initial feed for the New Britannia mill. Recoveries of copper, gold and silver at the Flin Flon concentrator during the first quarter of 2021 were higher than the previous quarter due to higher head grades from the mining out of higher grade remnant stopes at 777.

Combined mine, mill and G&A unit operating costs in the first quarter of 2021 increased by 8% compared to the fourth quarter of 2020, but remained within the annual guidance range. The increase was primarily due to lower capitalized development at both Lalor and 777, as well as higher mining activity at Lalor to grow the gold stockpile.

Manitoba's cash cost per pound of copper produced, net of by-product credits, for the first quarter of 2021 was negative $1.04, higher than the prior quarter primarily due to higher mining and general and administrative costs and lower by-product credits, offset by higher copper production. Manitoba's sustaining cash cost per pound of copper produced, net of by-product credits, in the first quarter of 2021 was $1.62, higher than the previous quarter due to the same factors affecting cash costs.

COVID-19 Business Update

The COVID-19 pandemic continues to have a significant global impact as the one-year anniversary of the global outbreak is marked. Throughout this time, Hudbay has prioritized the health and safety of its people by adapting its processes and procedures based on the local situation and taking proactive measures to prevent or minimize the spread of COVID-19 within its workplaces.

As cases of COVID-19 remain elevated in Peru and continue to rise near the company's operations in Manitoba, Hudbay has experienced limited transmission at both of its operations. The company has responded to these events quickly and has worked collaboratively with local health authorities to contain outbreaks while strengthening preventative measures at the workplace with negligible production or financial impacts. Hudbay believes it is appropriately enhancing its preventative and monitoring activities as the challenges of the pandemic evolve, but the company remains at increased operational risk. The company continues to monitor the risks of the pandemic at each of its locations to ensure the safety of its workforce, their families, and the communities in which the company operates.

Increased Constancia Reserves and Updated Mine Plan

On March 29, 2021, Hudbay released an updated mine plan for the Constancia operations that reflects an increase in copper and gold production from 2022 to 2025 as the higher grades from the Pampacancha deposit enter the mine plan. The updated mine plan incorporates higher-grade reserves from the Constancia North pit extension, which contributed to an increase in reserves of 33 million tonnes at a grade of 0.48% copper and 0.115 grams per tonne gold and extends the higher grade profile to 2028. This resulted in an increase of approximately 11% in contained copper and 12% in contained gold over the prior year's reserves, after adjusting for mining depletion in 2020.

With the incorporation of Pampacancha and Constancia North, annual production at Constancia is expected to average approximately 102,000 tonnes of copper and 58,000 ounces of gold over the next eight years, an increase of 40% and 367%, respectively, from 2020 levels, which were partially impacted by an eight-week temporary mine interruption related to a government-declared state of emergency. Constancia's total copper and gold production increases by 12% and 9%, respectively, compared to the same period in the company's previous technical report. Constancia maintains its low-cost profile with average cash cost and sustaining cash cost of $1.18 and $1.71, respectively, per pound of copper produced, net of by-product credits, over the next eight years.

New Britannia Mill Refurbishment Update and Snow Lake Updated Mine Plan

The New Britannia project continues to track ahead of the original schedule and is nearing completion with approximately 82% of the project completed at the end of April. Commissioning of the gold plant is expected in mid-2021 with first gold production expected early in the third quarter. The new copper flotation facility is on track for commissioning and ramp-up in the fourth quarter of 2021. Operational readiness activities are progressing as planned with underground development of Lalor's gold-rich lenses well-advanced in preparation for the start-up of New Britannia. The company continues to see some COVID-related cost pressures on the project capital estimate at New Britannia.

On March 29, 2021, Hudbay announced that the company has advanced the third phase of its Snow Lake gold strategy focusing on expansion and further optimization of operations. Various mining and milling optimization opportunities have been incorporated into an updated mine plan, which contemplates an increase in annual gold production from Lalor and the Snow Lake operations from approximately 150,000 ounces to over 180,000 ounces during the first six years of New Britannia's operation at cash cost and sustaining cash cost, net of by-product credits, of $412 and $788 per ounce of gold, respectively. Mineral reserves increased year-over-year, which resulted in no change to Snow Lake's mine life (to 2037) as the company accelerated future reserves with a higher production rate at Lalor and Stall. This enhanced mine plan incorporates the results from several optimization initiatives, including:

TSX, NYSE - HBM<br><br> <br>2021 No. 12

• Early gold production at New Britannia expected in the third quarter of 2021, ahead of the original schedule;
• Increasing the Lalor mining rate to 5,300 tonnes per day from 4,500 tonnes per day in the previous mine plan, which is expected to begin after the 777 mine closes in mid-2022;
• Adding the 1901 deposit to the mine plan to include 1.58 million tonnes of reserves at a grade of 7.9% zinc, with production expected to commence in 2026 at a rate of approximately 1,000 tonnes per day;
• Higher throughput at Stall to achieve a rate of 3,800 tonnes per day compared to 3,500 tonnes per day in the previous mine plan; and
• Starting in 2023, increased copper and precious metal recoveries at Stall, where capital upgrades of $19 million are expected to increase Stall's copper recoveries to between 91% and 95%, gold recoveries to between 64% and 70%, and silver recoveries to between 65% and 74%, a significant increase from the assumed recoveries in the previous mine plan of 84% copper, 53% gold and 53% silver.

These mine plan enhancements optimize the processing capacity of the Snow Lake operations in a manner that maximizes the net present value of the operations. As a result of these initiatives, the production of gold, copper and silver are expected to increase by 18%, 35% and 27%, respectively, from 2022 to 2027 compared to the previous mine plan.

Pampacancha First Production Achieved

In early April 2021, the company finalized the remaining land user agreement for Pampacancha and gained full access to the site to complete pit development activities. Blasting began in mid-April and first production from Pampacancha was achieved at the end of April, which is consistent with Hudbay's previous 2021 guidance and recently published mine plan.

As a result of the completion of the individual land user agreements, revised growth capital expenditure guidance for Peru has increased to approximately $25 million in 2021.

Growing Near-term Production Outlook

On March 29, 2021, Hudbay announced its updated three-year production outlook. Consolidated copper and gold production are expected to increase to 129,500 tonnes and 280,000^ii^ ounces, respectively, in 2023, which represents an increase of 36% and 125%^ii^, respectively, from 2020 levels as Hudbay brings its Pampacancha and New Britannia projects into production. These growth projects more than offset the lost copper and gold production from 777 after its closure in mid-2022.

Rosemont Update

The appeal of the unprecedented Rosemont court decision with the U.S. Court of Appeals for the Ninth Circuit continues with a decision expected in the second half of 2021. In March 2021, the U.S. Army Corps of Engineers (the "Corps") granted an approved jurisdictional determination whereby the Corps determined there are no waters of the United States on the Rosemont property, and therefore, Rosemont does not require a Section 404 Water Permit.

Expanded Exploration Program at Copper World Discovery

On March 29, 2021, Hudbay announced the intersection of high-grade copper sulphide and oxide mineralization at shallow depth on its wholly-owned private land located within seven kilometres of the Rosemont copper project in Arizona. A 40,000-foot drill program was initiated in 2020 to confirm historical drilling in this past-producing copper region formerly known as Helvetia. After receiving encouraging initial results in February 2021, the company launched a larger 70,000-foot drill program and increased the number of drill rigs at site to further test the four deposits at Copper World and the potential for additional mineralization.

TSX, NYSE - HBM<br><br> <br>2021 No. 12

Hudbay's 2020 drill program confirmed the discovery of the Broad Top Butte, Copper World, Peach and Elgin deposits, with a combined strike length of over five kilometres and opportunities to discover additional mineralization between the deposits. The program intersected significant volumes of high-grade copper sulphide and oxide mineralization starting, in most cases, near surface or at shallow depth. Drilling at Broad Top Butte included intersections of 440 feet of 1.38% copper and 246 feet of 0.70% copper starting at surface. Drilling at the Peach and Eglin deposits included intersections of 500 feet of 0.82% copper and 300 feet of 0.64% copper, both starting from surface. The mineralization at the Copper World deposits is located closer to surface than at Rosemont and remains open at depth.

Given the continued success from the Copper World exploration program, in April 2021, Hudbay increased the 2021 budget by approximately $24 million, which includes approximately $14 million for additional exploration expenditures and approximately $10 million of operational expenses related to further studies, none of which will be capitalized. The additional exploration activities are expected to include resource definition drilling and testing targets on Hudbay's private land. The additional studies relate to planned hydrogeological, geotechnical and other studies to potentially support future economic assessments and mine plans. Mineralogical studies and metallurgical testing have also been initiated and are expected to continue in the coming months. Geophysical surveys have been completed and are being analyzed to identify further targets on the company's private land package. Depending on the exploration program results, Hudbay expects to complete an initial inferred resource estimate before the end of the year and a preliminary economic assessment in the first half of 2022.

Increased Resource Estimate and Positive Preliminary Economic Assessment at Mason

The Mason project is a 100%-owned greenfield copper deposit located in the historic Yerington District of Nevada and is one of the largest undeveloped copper porphyry deposits in North America. In March 2021, Hudbay announced its first compiled resource estimate for the Mason project based on a resource model constructed using the same methods applied at Constancia. This resulted in a measured and indicated resource estimate of 2.2 billion tonnes at 0.29% copper, which increased from 1.4 billion tonnes at 0.32% copper previously.

The recently completed PEA contemplates a 27-year mine life with average annual copper production of approximately 140,000 tonnes over the first ten years of full production. The mine plan assumes the construction of a 120,000 tonnes per day conventional flotation concentrator and an initial capital cost estimate of approximately $2.1 billion. At a copper price of $3.10 per pound, the after-tax net present value using a 10% discount rate is $519 million and the internal rate of return is approximately 14%. The valuation metrics are highly sensitive to the copper price and at a price of $3.25 per pound, the after-tax net present value using a 10% discount rate increases to $773 million and the internal rate of return increases to approximately 15%.

There remain opportunities to further enhance the project economics through exploration for higher grade satellite deposits on the company's prospective land package in Nevada, including the Mason Valley properties. Much of the Mason Valley property is located on Hudbay's wholly owned private lands and contains highly prospective skarn mineralization in an area that hosts several historical underground copper mines. Historical drilling and production records from the past producing mines at Mason Valley indicate the mineralization is high grade and starts at or near surface, similar to Hudbay's Copper World property in Arizona. The company expects to continue to compile and interpret historical data on its land package near Mason, to be followed by a geophysical survey to refine the exploration targets in preparation for a future drilling campaign.

Other Exploration Update

Constancia Regional Exploration

In addition to increasing Constancia's reserves, the Constancia North discovery also contributed to an improvement in the head grade of the Constancia mine mineral resource estimates: measured and indicated copper grades increased to 0.22% from 0.19% and inferred copper grades increased to 0.30% from 0.18%. A significant portion of the Constancia North resource estimate is classified as inferred due to wide drill spacing but there remains the opportunity to upgrade these inferred resources to a higher classification as the company completes infill drilling. There also remains further opportunity to extend the Constancia North resources by incorporating steeply dipping high-grade skarn mineralization through a potential underground operation and a trade-off study between open pit versus underground development is expected to be completed in 2021. The mineralization remains open down plunge to the north.

Hudbay continues to advance regional exploration programs in Peru. In February 2021, the company commenced drilling on the Quehuincha North high-grade skarn target located approximately 10 kilometres from Constancia, and drilling continues with five holes completed to-date. Discussions continue to progress with the community of Uchucarcco on the Maria Reyna and Caballito properties, both of which are located within ten kilometres of Constancia, and the company expects to reach an agreement this year. Hudbay also expects to commence drilling activities at the Llaguen property in the coming weeks. Llaguen is a copper porphyry target located in northern Peru, near the city of Trujillo and in close proximity to existing infrastructure.

Snow Lake Regional Exploration

Exploration efforts at the Lalor mine in 2020 continued to be successful with the definition of an additional 1.8 million tonnes of mineral resources, increasing total inferred mineral resources at Lalor to 6.2 million tonnes. The inferred resources have the potential to extend the Lalor mine life beyond the current estimate of ten years and maintain the 5,300 tonnes per day production level beyond 2027.

Preliminary results from Hudbay's 2021 winter drill program in the Chisel Basin in Snow Lake indicate that a potential copper-gold feeder zone to the 1901 deposit exists with one hole intersecting 11.6 metres at 2.7% copper and 3.4 grams per tonne gold, which is similar to the known geology at the Lalor deposit. A review is underway to determine next steps for exploration at 1901 and whether it will be best conducted from surface or from underground once development of the deposit has commenced and suitable drill platforms can be established. The company also continues to test other targets within the Chisel Basin.

Senior Unsecured Notes Refinancing

On March 8, 2021, Hudbay completed the offering of $600.0 million aggregate principal amount of 4.5% senior notes due April 2026 (the "New Notes"). The New Notes are governed by an indenture, dated as of March 8, 2021, among the company, the subsidiaries of the company party thereto as guarantors and U.S. Bank National Association, as trustee.

The proceeds from this offering, together with available cash on hand, were used to redeem all $600.0 million of Hudbay's outstanding 7.625% senior notes due 2025 (the "Redeemed Notes"), including the payment of accrued and unpaid interest and $31.0 million in net transaction and early redemption costs associated with the New Notes. The lower interest rate on the New Notes, versus the rate on the Redeemed Notes, will result in reduced cash interest payments of almost $19 million annually.

TSX, NYSE - HBM<br><br> <br>2021 No. 12

Collective Bargaining Agreements

The collective bargaining agreements with Hudbay's unionized workforces at each of its Peru and Manitoba operations expired on or about December 31, 2020. The company continues to advance the collective bargaining process with the labour unions in each jurisdiction as it works toward renewing the collective agreements.

Wheaton Agreement Amendment related to Pampacancha Delivery Obligation

On May 10, 2021, an amendment to the Constancia streaming agreement was signed with Wheaton. The amendment eliminates the requirement to deliver an additional 8,020 ounces of gold to Wheaton for not mining four million tonnes of ore from the Pampacancha deposit by June 30, 2021. As part of this amendment, Hudbay has agreed to increase the fixed gold recoveries that apply to Constancia ore production from 55% to 70% during the reserve life of Pampacancha, which matches the fixed rate of recovery that applies to Pampacancha production. In addition, if Hudbay mines and processes four million tonnes of ore from the Pampacancha deposit by December 31, 2021, Wheaton will make an additional deposit payment of $4 million.

Non-IFRS Financial Performance Measures

Adjusted net earnings (loss), adjusted net earnings (loss) per share, adjusted EBITDA, net debt, cash cost, sustaining and all-in sustaining cash cost per pound of copper produced and per ounce of gold produced and combined unit cost are non-IFRS performance measures. These measures do not have a meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other issuers. These measures should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS and are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. Other companies may calculate these measures differently.

Hudbay believes adjusted net earnings (loss) and adjusted net earnings (loss) per share better reflect the company's performance for the current period and are better indications of its expected performance in future periods. These measures are used internally by the company to evaluate the performance of its underlying operations and to assist with its planning and forecasting of future operating results. As such, the company believes these measures are useful to investors in assessing the company's underlying performance. The company provides adjusted EBITDA to help users analyze its results and to provide additional information about the company's ongoing cash generating potential in order to assess its capacity to service and repay debt, carry out investments and cover working capital needs. Net debt is shown because it is a performance measure used by the company to assess its financial position. Cash cost, sustaining and all-in sustaining cash cost per pound of copper produced and per ounce of gold produced are shown because the company believes they help investors and management assess the performance of its current and future operations, including the margin generated by the operations and the company. Combined unit cost is shown because the company believes it helps investors and management assess the cost structure and margins that are not impacted by variability in by-product commodity prices.

For further details on these measures, including reconciliations to the most comparable IFRS measures, please refer to page 39 of Hudbay's management's discussion and analysis for the three months ended March 31, 2021 available on SEDAR at www.sedar.com.

Notes to Unaudited Condensed Consolidated Interim Financial Statements<br>(in thousands of US dollars, except where otherwise noted)<br>For the three months ended March 31, 2021 and 2020

1. Reporting entity

On January 1, 2017, Hudbay Minerals Inc. amalgamated under the Canada Business Corporations Act with its subsidiaries Hudson Bay Mining and Smelting Co., Limited and Hudson Bay Exploration and Development Company Limited to form Hudbay Minerals Inc. ("HMI" or the "Company"). The address of the Company's principal executive office is 25 York Street, Suite 800, Toronto, Ontario. The unaudited condensed consolidated interim financial statements ("interim financial statements") of the Company for the three months ended March 31, 2021 and 2020 represent the financial position and the financial performance of the Company and its subsidiaries (together referred to as "Hudbay").

Wholly owned subsidiaries as at March 31, 2021 and 2020 include HudBay Marketing & Sales Inc. ("HMS"), HudBay Peru Inc., HudBay Peru S.A.C. ("Hudbay Peru"), HudBay (BVI) Inc., Hudbay Arizona Inc, Rosemont Copper Company ("Rosemont") and Mason Resources (US) Inc. ("Mason").

Hudbay is an integrated mining company primarily producing copper concentrate (containing copper, gold and silver), molybdenum concentrate and zinc metal. With assets in North and South America, Hudbay is focused on the discovery, production and marketing of base and precious metals. Directly and through its subsidiaries, Hudbay owns three polymetallic mines, four ore concentrators and a zinc production facility in northern Manitoba and Saskatchewan (Canada) and Cusco (Peru) and copper projects in Arizona and Nevada (United States). Hudbay also has equity investments in a number of junior exploration companies. The Company is governed by the Canada Business Corporations Act and its shares are listed under the symbol "HBM" on the Toronto Stock Exchange, New York Stock Exchange and Bolsa de Valores de Lima.

2. Basis of preparation

(a) Statement of compliance:

These interim financial statements have been prepared in accordance with IAS 34, Interim Financial Reporting as issued by the International Accounting Standards Board ("IASB") and do not include all of the information required for full annual financial statements by International Financial Reporting Standards ("IFRS").

These interim financial statements should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2020 which includes information necessary or useful to understanding the Company's business and financial statement presentation. In particular, the Company's significant accounting policies are presented as note 3 in the audited consolidated financial statements for the year ended December 31, 2020 and have been consistently applied in the preparation of these interim financial statements.

The Board of Directors approved these interim financial statements on May 11, 2021.

HUDBAY MINERALS INC.
Notes to Unaudited Condensed Consolidated Interim Financial Statements<br>(in thousands of US dollars, except where otherwise noted)<br>For the three months ended March 31, 2021 and 2020

(b) COVID-19 estimation uncertainty:

At the end of 2019, a novel strain of coronavirus ("COVID-19") was first reported. The COVID-19 outbreak has developed rapidly in 2020 and into 2021, with a significant number of infections around the world, including regions Hudbay operates in. On March 11, 2020, the World Health Organization declared the COVID-19 outbreak a global pandemic. Since then, containment measures have resulted in decreased economic activity, which has adversely affected the broader global economy.

The resulting impacts on global commerce have been and continue to be far-reaching. Since the initial outbreak there has been volatility in stock markets, commodities and foreign exchange markets, restrictions on the conduct of business in many jurisdictions and the global movement of people and some goods have become restricted.

The Company has evaluated the potential impacts arising from COVID-19 on all aspects of its business.

(c) Use of judgements and estimates:

The preparation of the interim financial statements in conformity with IFRS requires Hudbay to make judgements, estimates and assumptions, in applying accounting policies that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim financial statements, as well as reported amounts of revenue and expenses during the reporting period. Actual results may differ from these judgements, estimates and assumptions. The interim financial statements reflect the judgements and estimates outlined by Hudbay in its audited consolidated financial statements for the year ended December 31, 2020, except as noted below.

As a result of a new National Instrument 43-101 ("NI 43-101") technical report for the Constancia copper mine in Peru, effective January 1, 2021, which reflects an updated mine plan with a new grade and ore tonnage profile, Hudbay made a change in estimate in Peru for the allocation of mining cost to inventories and depreciation for certain mineral property, property plant and equipment ("PP&E") assets, to reflect the changes in grades following the new NI 43-101 to utilize contained metal in the respective calculations. Please see notes 5b, 7 and 10 for further details on the impact of this change in estimation method.

During the current period, as a result of volatile discount rates and inflation rates, management re-examined the inflation estimate used to calculate the decommissioning, restoration and similar liabilities ("DRO"). It was concluded that the implied difference between the nominal bond yield and the corresponding maturity real return bond yield provides a more accurate estimate of the effective inflation rate. As such, during the current period, the inflation rate estimate used to calculate DRO has been prospectively revised. Please see notes 5d and 16 for further details on the impact of this change in estimation method.

3. Significant accounting policies

These interim financial statements reflect the accounting policies applied by Hudbay in its audited consolidated financial statements for the year ended December 31, 2020 and comparative periods.

HUDBAY MINERALS INC.
Notes to Unaudited Condensed Consolidated Interim Financial Statements<br>(in thousands of US dollars, except where otherwise noted)<br>For the three months ended March 31, 2021 and 2020

4. New standards

New standards and interpretations adopted

(a) Amendment to IAS 16 - Property, Plant and Equipment

The amendments to IAS 16 prohibit deducting from the cost of property, plant and equipment the proceeds from selling items produced while bringing the assets to the location and condition necessary for them to be capable of operating in the manner intended by management. Instead, a company will recognize such sales proceeds and related cost in profit or loss. This amendment is in effect January 1, 2022 with early adoption permitted.

Hudbay has early adopted this amendment as of January 1, 2021 with retrospective application only to items of property, plant and equipment that were brought to the location and condition necessary for them to be capable of operating in the manner intended by management on or after January 1, 2020. No restatement of prior periods was required on adoption given the comparable periods contained no items would have been impacted by this accounting amendment.

(b) Interest Rate Benchmark Reform - Phase II - Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 6

These amendments require companies to determine if there is a significant change in the basis of determining contractual cash flows as a result of interest rate benchmark reform / IBOR reform. A company will be required to determine if the replacement of an existing interest rate benchmark with an alternative rate benchmark results in contractual cash flows that are significantly different for financial instruments, lease payments, insurance contracts and/or items that use hedge accounting. If IBOR reform result in a transition on an economically equivalent basis with no value transfer having occurred, the changes to the standard allow the contractual cash flow changes to be applied prospectively, similar to a change in a market rate. For Hudbay, these amendments have been in effect since January 1, 2021 and have not resulted in material changes to the interim financial statements.

During the first quarter of 2021, Hudbay has not entered into any new contracts or contract modifications that are dependent on the LIBOR rate.

Notes to Unaudited Condensed Consolidated Interim Financial Statements<br>(in thousands of US dollars, except where otherwise noted)<br>For the three months ended March 31, 2021 and 2020

Consideration from the Company's stream agreements is considered variable (note 15). Gold and silver stream revenue can be subject to cumulative adjustments when the amount of precious metals to be delivered under the contract changes. As a result of changes in the Company's mineral reserve and resource estimate in the first quarter of 2021, the amortization rate by which deferred revenue is drawn down into income was adjusted and, as required, a current period catch up adjustment is made for all prior year stream revenues since the stream agreement inception date. This variable consideration adjustment for the three months ended March 31, 2021 resulted in an increase of revenue of $1,617. The variable consideration adjustment for the three months ended March 31, 2020 resulted in a reversal of revenue of $2,813.

(b) Depreciation and amortization

Depreciation of PP&E and amortization of intangible assets are reflected in the  condensed consolidated interim income statements as follows:

		Three months <br>ended March 31,
		2021		2020
Cost of sales	$	82,682	$	86,439
Selling and administrative expenses		480		418
	$	83,162	$	86,857

Effective January 1, 2021, following a new NI 43-101 technical report for Peru, the Company made a change in estimate in Peru for certain mineral property PP&E assets to reflect the changes in grades following the new NI 43-101 to utilize contained metal in the depreciation calculation. For the first quarter of 2021, depreciation expense is lower by $887 compared to the result under the previous depreciation calculation. Since the change is in response to an updated life-of-mine plan it is being treated in accordance with a change in estimate and has been applied prospectively. Please see Note 10 for further details.

During the first quarter of 2021, the Company revalued its DRO using the prevailing market discount rates, as it does every quarter in the normal course. Due to rising risk-free rates during the first quarter, discount rates used in the revaluation of the DRO have increased correspondingly, resulting in a reduction in the associated liabilities. For certain closed sites with such reclamation obligations, the revaluation of the corresponding liability is recorded through the income statement, resulting in a gain of $4,499.

The cost of inventories recognized as an expense, including depreciation, and included in cost of sales amounted to $237,398 for the three months ended March 31, 2021 (three months ended March 31, 2020 - $229,193).

During the three months ended March 31, 2021, Hudbay recognized a recovery of $723 in cost of sales related to adjustments of the carrying value of inventories to net realizable value (three months ended March 31, 2020 - a net expense of $10,375). Adjustments to the carrying value of inventories to net realizable value were related to changes in commodity prices.

Effective January 1, 2021, following a new NI 43-101 technical report for Peru, which reflects an updated mine plan with a new grade and ore tonnage profile, the Company changed its method of estimation with respect to applying mining costs to stockpile and finished goods inventory. Prior to this change, mining costs were allocated using tonnes of ore mined. Starting January 1, 2021 Peru mining cost have been allocated to inventories using contained metal, incorporating tonnes of ore mined and expected mined grades. Since the change is in response to an updated life-of-mine plan, it is being treated in accordance with a change in estimate and will be applied prospectively. For the first quarter of 2021, as a result of the change in allocation, stockpile and finished goods inventories have declined and increased by $2,574 and $69, respectively.

All values are in US Dollars.

For the three months ended March 31, 2021, the increase in property, plant and equipment (cost) of $61,255 was mainly caused by fixed asset and construction in progress asset additions of $101,003 and effects of movements in exchange rates of $26,441, partially offset by decreases in decommissioning and restoration assets of $64,504 (producing assets) mostly as a result of changes in discount rates associated with remeasurement of the liabilities.

Effective January 1, 2021, following a new NI 43-101 technical report for Peru, the Company made a change in estimate in Peru for certain mineral property PP&E assets to reflect the changes in grades following the new NI-43-101 to utilize contained metal in the depreciation calculation.

The change is in response to an updated life-of-mine plan, it is being treated in accordance with a change in estimate and will be applied prospectively. For the first quarter of 2021, depreciation expense is lower by $887 compared to the result under the previous depreciation calculation.

Hudbay has entered into leases for its Peru, Manitoba and Arizona business units which expire between 2021 and 2043. The interest rates on leases which were capitalized have interest rates between 1.95% to 5.44%, per annum. The range of interest rates utilized for discounting varies depending mostly on the Hudbay entity acting as lessee and duration of the lease. For certain leases, Hudbay has the option to purchase the equipment and vehicles leased at the end of the terms of the leases. Hudbay's obligations under these leases are secured by the lessor's title to the leased assets. The present value of applicable lease payments has been recognized as a ROU asset, which was included as a non-cash addition to property, plant and equipment, and a corresponding amount as a lease liability.

There are no restrictions placed on Hudbay by entering into these leases.

The following outlines expenses recognized within the Company's condensed consolidated interim income statements for the periods ended March 31, 2021 and March 31, 2020, relating to leases for which a recognition exemption was applied.

		Three months ended <br>March 31,

Short-term leases	$	8,539	$	12,697
Low value leases		93		80
Variable leases		8,083		10,531
Total	$	16,715	$	23,308

Payments made for short term, low value and variable leases would mostly be captured as expenses in the condensed consolidated interim income statements, however, certain amounts may be capitalized to PP&E for the Arizona business unit during its development phase and certain amounts may be reported in inventories given the timing of sales. Variable consideration leases include equipment used for heavy civil works at Constancia.

On March 8, 2021, Hudbay completed an offering of $600,000 aggregate principle amount of 4.50% senior unsecured notes due April 2026 (the "2026 Notes").

Hudbay used the proceeds of the offering, together with available cash on hand, to satisfy and discharge all of its obligations with respect to its then outstanding $600,000 aggregate principal amount of 7.625% senior unsecured notes due 2025 (the "2025 Notes").

The unamortized transaction costs of $2,480 were expensed upon extinguishment of the 2025 Notes. The early redemption of these notes resulted in a charge of $22,878, which was recorded on the condensed consolidated interim income statements (note 5e).

The early redemption of the 2025 Notes reflected the exercise of a prepayment option previously valued at $49,754. As such, the prepayment option has been expensed in the condensed consolidated interim income statements (note 5e).

On September 23, 2020, Hudbay completed an offering of $600,000 aggregate principal amount of 6.125% senior unsecured notes due April 2029 (the "2029 Notes").

15. Deferred revenue

On August 8, 2012 and November 4, 2013, Hudbay entered into precious metals stream transactions with Wheaton Precious Metals ("Wheaton") whereby Hudbay has received aggregate deposit payments of $455,100 against delivery of (i) 100% of payable gold and silver from the 777 mine until the end of 2016, and delivery of 50% of payable gold and 100% of payable silver for the remainder of the 777 mine life; and aggregate deposit payments of $429,900 against the delivery of (ii) 100% of payable silver and 50% of payable gold from the Constancia mine.

In addition to the aggregate deposit payments of $885,000, as gold and silver is delivered under the stream agreements, Hudbay receives cash payments equal to the lesser of (i) the market price and (ii) $400 per ounce (for gold) and $5.90 per ounce (for silver), subject to 1% annual escalation after three years, from the inception of the agreement.

Hudbay recorded the deposits received as deferred revenue and recognizes amounts in revenue as gold and silver are delivered under the stream agreements. Hudbay determines the amortization of deferred revenue to the condensed consolidated interim income statements on a per unit basis using the estimated total number of gold and silver ounces expected to be delivered under the stream agreements over the life of the 777 and Constancia life-of-mine plans. During the third quarter of 2020, Hudbay revised its estimate of remaining mineralization for the 777 deposit and as such adjusted the drawdown rates for the remainder of the year. For the three months ended March 31, 2021 the drawdown rates for the 777 stream agreement for gold and silver were CA$1,578 and CA$30.38 per ounce, respectively (year ended December 31, 2020 - $1,173 and $22.43 per ounce, respectively). For the three months ended March 31, 2021 the drawdown rates for the Constancia stream agreement for gold and silver were $990 and $21.86 per ounce, respectively (year ended December 31, 2020 - $976 and $21.52 per ounce, respectively). Hudbay estimates the current portion of deferred revenue based on deliveries anticipated over the next twelve months.

Hudbay has determined that precious metals stream contracts are subject to variable consideration and contain a significant financing component. As such, the Company recognizes a financing charge at each reporting period and will gross up the deferred revenue balance to recognize the significant financing element that is part of these contracts. Hudbay's streaming arrangements are secured against the mining properties and other business unit assets associated with the applicable stream.

Hudbay expects that the remaining performance obligations for the 777 and Constancia streams will be settled by the expiry of their respective stream agreements, which is no earlier than 2052.

As part of the streaming agreement for the 777 mine, Hudbay must repay, with precious metals credits, the legal deposit provided by August 1, 2052, the expiry date of the agreement. If the legal deposit is not fully repaid with precious metals credits from 777 production by the expiry date, a cash payment for the remaining amount will be due at the expiry date of the agreement. Given the mineral reserve and resources of the 777 mine and the current mine plan, there is a possibility that an amount of the legal deposit may not be repaid by means of 777 mine's precious metals credits over its expected remaining mine life. As at March 31, 2021, this prepayment amount does not meet the definition of a financial liability. Hudbay incorporates the possibility of repayment as part of its assessment of variable consideration in recognizing the amount of deferred revenue to recognize in income.

Consideration from the Company's stream agreement is considered variable. Gold and silver stream revenue can be subject to cumulative adjustments when the number of ounces to be delivered under the contract changes. As a result of changes in the Company's mineral reserve and resource estimate in the first quarter of 2021, the amortization rate by which deferred revenue is drawn down into income was adjusted and, as required, a current period catch up adjustment is made for all prior period stream revenues since the stream agreement inception date. This variable consideration adjustment resulted in an increase in revenue of $1,617 and an increase of finance expense of $594 for the three months ended March 31, 2021 (December 31, 2020 - increase in revenue of $6,668 and reversal of finance expense of $3,692).

During the year ended December 31, 2020 the Company recognized an adjustment to gold and silver revenue and finance costs due to a net increase in the Company's mineral reserve and resources estimates coupled with a change to the 777 mine plan.

Deferred revenue is reflected in the condensed consolidated interim balance sheets as follows:

The following table summarizes changes in decommissioning, restoration and similar liabilities:

Balance, December 31, 2020	$	343,132
Net additional provisions made		(2,930	)
Disbursements		(4,637	)

Effect of change in nominal discount rate		(53,850	)
Effect of foreign exchange		2,967
Balance, March 31, 2021	$	273,248
^1^Represents changes in estimates of inflation rates applied to expected undiscounted cash flows.

DRO are remeasured at each reporting date to reflect changes in discount rates, exchange rates, and timing and extent of cash outflows which can significantly affect the liabilities. The amount of this provision has been recorded based on estimates and assumptions that management believes are reasonable; however, actual decommissioning and restoration costs may differ from expectations.

During the current period, as a result of volatile discount rates and inflation rates, management re-examined the inflation estimate used to calculate the DRO liability. It was concluded that the implied difference between the nominal bond yield and the corresponding maturity real return bond yield provides a more accurate estimate of the effective inflation rate. As such, during the current period, the inflation rate estimate used to calculate DRO has been prospectively revised.

The effect of the change in estimate has resulted in a net decrease to the DRO liability of $12,295.

As at March 31, 2021, decommissioning, restoration and similar liabilities have been discounted to their present value at nominal rates ranging from 0.08% to 2.41% per annum (December 31, 2020: 0.12% to 1.65%), using pre-tax risk-free interest rates that reflect the estimated maturity of each specific liability.

19. Earnings per share

	Three months ended
	Mar. 31, 2021	Mar. 31, 2020
Basic and diluted weighted average common shares outstanding	261,321,074	261,272,151

The determination of the diluted weighted-average number of common shares excludes the impact of 509,385 weighted-average stock options outstanding that were anti-dilutive for the three months ended March 31, 2021 (March 31, 2020 - nil).

For periods where Hudbay records a loss, Hudbay calculates diluted loss per share using the basic weighted average number of shares. If the diluted weighted average number of shares were used, the result would be a reduction in the loss, which would be anti-dilutive. For the three months ended March 31, 2021 and 2020, Hudbay calculated diluted loss per share using 261,321,074 and 261,272,151 common shares, respectively.

1 Cash and cash equivalents, restricted cash, trade and other receivables and trade and other payables are recorded at carrying value, which approximates fair value due to their short-term nature and generally negligible credit losses.
2 Excludes tax and other statutory amounts.
3 Trade and other receivables contain receivables including provisionally priced receivables classified as FVTPL and various other items at amortized cost. The fair value of provisionally priced receivables is determined using forward metals prices which is a level 2 valuation method.
4 Derivatives are carried at their fair value, which is determined based on internal valuation models that reflect observable forward market commodity prices, currency exchange rates, and discount factors based on market US dollar interest rates adjusted for credit risk.
5 All investments are carried at their fair value, which is determined using quoted market bid prices in active markets for listed shares.
6 These financial liabilities relate to agreements with communities near the Constancia project in Peru (note 12). Fair values have been determined using a discounted cash flow analysis based on expected cash flows and a credit adjusted discount rate.
7 Fair value of the senior unsecured notes (note 14) has been determined using the quoted market price at the period end. Fair value incorporates the fair value of the prepayment option embedded derivative. The carrying value of this embedded derivative is at FVTPL (2021: nil; 2020: 49,754) and has been determined using a binomial tree/lattice approach based on the Hull-White single factor interest rate term structure model.
8 Discounted value based on a risk adjusted discount rate.
9 The gold prepayment liability (note 12) is designated as fair value through profit or loss under the fair value option.  Gains and losses related to the Company's own credit risk have been recorded at fair value through other comprehensive income. The fair value adjustment recorded in other comprehensive income for the three months ended March 31, 2021 was a loss of 1,547 (year ended December  31, 2020 was a loss of 1,885).

All values are in US Dollars.

Fair value hierarchy

The table below provides an analysis by valuation method of financial instruments that are measured at fair value subsequent to recognition. Levels 1 to 3 are defined based on the degree to which fair value inputs are observable and have a significant effect on the recorded fair value, as follows:

- Level 1: Quoted prices in active markets for identical assets or liabilities;

- Level 2: Valuation techniques use significant observable inputs, either directly or indirectly, or valuations are based on quoted prices for similar instruments; and,

- Level 3: Valuation techniques use significant inputs that are not based on observable market data.

The Company's policy is to recognize transfers into and transfers out of fair value hierarchy levels as of the date of the event or change in circumstances that caused the transfer. During the three months ended March 31, 2021 and year ended December 31, 2020, Hudbay did not make any such transfers.

(b) Derivatives and hedging:

Copper fixed for floating swaps

Hudbay enters into copper fixed for floating swaps in order to manage the risk associated with provisional pricing terms in copper concentrate sales agreements. As at March 31, 2021, Hudbay had 52.9 million pounds of net copper swaps outstanding at an effective average price of $3.73/lb and settling across April to July 2021. As at December 31, 2020, Hudbay had 43.4 million pounds of net copper swaps outstanding at an effective average price of $3.22/lb and settling across January to April 2021. The aggregate fair value of the transactions at March 31, 2021 was a liability of $13,371 (December 31, 2020 - a liability position of $13,198).

Transactions involving derivatives are with large multi-national financial institutions that Hudbay believes to be credit worthy.

Non-hedge derivative zinc contracts

Hudbay enters into future dated fixed price sales contracts with zinc customers and, to ensure that the Company continues to receive a floating or unhedged realized zinc price, Hudbay enters into forward zinc purchase contracts that effectively offset the fixed price sales contracts. At March 31, 2021, Hudbay held contracts for forward zinc purchased of 3.1 million pounds (December 31, 2020 - 3.5 million pounds) that related to forward customer sales of zinc. Prices range from $1.01/lb to $1.27/lb (December 31, 2020 - $0.87/lb to $1.30/lb) and settlement dates extend to December 2021. The aggregate fair value of the transactions at March 31, 2021 was an net asset position of $471 (December 31, 2020 - a net asset position of $622).

(c) Provisionally priced receivables

Changes in fair value of provisionally priced receivables

Hudbay records changes in fair value of provisionally priced receivables related to provisional pricing in concentrate purchase, concentrate sale and certain other sale contracts. Under the terms of these contracts, prices are subject to final adjustment at the end of a future period after title transfers based on quoted market prices during the quotation period specified in the contract. The period between provisional pricing and final pricing is typically up to three months.

Changes in fair value of provisionally priced receivables are presented in trade and other receivables when they relate to sales contracts and in trade and other payables when they relate to purchase contracts. At each reporting date, provisionally priced metals are marked-to-market based on the forward market price for the quotation period stipulated in the contract, with changes in fair value recognized in revenue for sales contracts and in inventory or cost of sales for purchase concentrate contracts. Cash flows related to changes in fair value of provisionally priced receivables are classified in operating activities.

Notes to Unaudited Condensed Consolidated Interim Financial Statements<br>(in thousands of US dollars, except where otherwise noted)<br>For the three months ended March 31, 2021 and 2020

As at March 31, 2021 and December 31, 2020, Hudbay's net position consisted of contracts awaiting final pricing which are as indicated below:

Metal in concentrate		Sales awaiting final pricing		Average YTD price (/unit)
	Unit	Mar. 31, 2021	Dec. 31, 2020	Mar. 31, 2021
Copper	pounds<br>(in thousands)	56,319	47,901	3.99
Gold	oz	15,736	18,106	1,714
Silver	oz	88,463	123,380	24.53

All values are in US Dollars.

The aggregate changes in fair value of provisionally priced receivables within the copper and zinc concentrate sales contracts at March 31, 2021, was an asset position of $18,511 (December 31, 2020 - an asset position of $21,295).

(d) Embedded derivatives

Prepayment option embedded derivative

The senior unsecured notes (note 14) contain prepayment options, which represent embedded derivatives that may require bifurcation from the host contract. When the prepayment options require bifurcation, they are measured at fair value, with changes in the fair value being recognized as change in fair value of financial instruments (note 5e). Neither the 2026 Notes nor the 2029 Notes contain prepayment options that require bifurcation from the host contract. The fair value of the embedded derivative at March 31, 2021 was nil (December 31, 2020 - $49,754).

(e) Other financial liabilities

Gold prepayment liability

The gold prepayment liability (note 12) requires settlement by physical delivery of gold ounces or equivalent gold credits. The fair value of the embedded derivative at March 31, 2021 was a liability of $126,078 (December 31, 2020 - $137,031).

(c) Non-cash transactions:

During the three months ended March 31, 2021 and 2020, Hudbay entered into the following non-cash investing and financing activities which are not reflected in the condensed consolidated interim statements of cash flows:

• Remeasurement of Hudbay's decommissioning and restoration liabilities for the three months ended March 31, 2021 led to a net decrease in related property, plant and equipment assets of $64,504 (three months ended March 31, 2020 - an increase of $41,759) mostly related to changes in discount rates associated with remeasurement of the liabilities.

• Property, plant and equipment included $1,321 (three months ended March 31, 2020 - $2,421) of capital additions related to the recognition of ROU assets and $18,757 of capital additions related to agreements with communities (three months ended March 31, 2020 - $83,214).

24. Events after the reporting period

On May 10, 2021, an amendment to the Constancia streaming agreement was signed with Wheaton. The amendment eliminates the requirement to deliver 8,020 ounces of gold to Wheaton for not mining four million tonnes of ore from the Pampacancha deposit by June 30, 2021. In consideration for the elimination of this delivery obligation, Hudbay has agreed to increase the fixed gold recoveries that apply to Constancia ore production from 55% to 70% until December 31, 2025, which matches the fixed rate of recovery that applies to Pampacancha production. In addition, if Hudbay mines and processes four million tonnes of ore from the Pampacancha deposit by December 31, 2021, Wheaton will make an additional deposit payment of $4,000. Management is evaluating the potential accounting implications of the amended streaming agreement in the second quarter of 2021.

Our growth strategy is focused on the exploration, development, operation, and optimization of properties we already control, as well as other mineral assets we may acquire that fit our strategic criteria. Our vision is to be a responsible, top-tier operator of long-life, low-cost mines in the Americas. We are governed by the Canada Business Corporations Act and our shares are listed under the symbol "HBM" on the Toronto Stock Exchange, New York Stock Exchange and Bolsa de Valores de Lima.

SUMMARY

First Quarter Operating and Financial Results

• Consolidated copper production in the first quarter was 24,553 tonnes at cash cost and sustaining cash cost per pound of copper produced, net of by-product credits, of $1.04 and $2.16, respectively. Consolidated gold production in the first quarter was 35,500 ounces, a record for Hudbay.

• Full year 2021 production and operating cost guidance reaffirmed; Pampacancha production commenced in April 2021, in line with guidance.

• First quarter Manitoba copper production significantly increased from 2020 levels primarily due to higher grades at 777 and higher recoveries at the Flin Flon concentrator; sales volumes were impacted by the availability of railcars during the quarter with 5,000 tonnes of copper concentrate inventory in excess of normal operating levels, valued at approximately $18 million.

• First quarter Peru sales impacted by a 10,000 tonne shipment of copper concentrate, valued at approximately $21 million, for which a payment was received but not recorded as revenue due to the timing of the shipment being delayed to early April. Peru's production in the first quarter was impacted by increased ore hardness as well as a semi-annual scheduled plant shutdown in January.

• First quarter net loss and loss per share were $60.1 million and $0.23, respectively. After adjusting for one-time financing charges mainly related to the redemption of the 2025 senior notes and a revaluation of the gold prepayment liability, first quarter adjusted net loss^1^ per share was $0.06. First quarter adjusted EBITDA^1^ was $104.2 million.

• Operating cash flow before change in non-cash working capital increased to $90.7 million in the first quarter of 2021, from $42.0 million in the same quarter of 2020 due to higher realized metal prices and higher zinc sales volumes, partially offset by lower sales volumes of copper and precious metals.

• Cash and cash equivalents decreased during the first quarter to $310.6 million, as at March 31, 2021 mainly as a result of $83.0 million of capital investments primarily for the New Britannia project and Pampacancha development activities, $50.8 million of interest payments and $31.0 million in net transaction and early redemption costs related to the refinancing of our 2025 notes, partially offset by cash generated from operations.

Executing on Growth Initiatives

• Announced three-year production guidance; consolidated copper and gold production are expected to increase by 36% and 125%^2^, respectively, by 2023 from 2020 levels as we bring the Pampacancha and New Britannia growth projects into production.

• Finalized the remaining land user agreement for Pampacancha in early April 2021. This provided us with full access to the site to complete pit development and commence first ore production in late April, in line with timelines assumed in our updated mine plan. Total 2021 growth capital guidance for Peru has increased to $25 million to include the final land user costs.

• New Britannia project continues to track ahead of the original schedule and is nearing completion, with approximately 82% of the project completed at the end of April; first gold production continues to be expected early in the third quarter and the new copper flotation facility remains on track for commissioning and ramp-up in the fourth quarter of 2021.

• Announced a year-over-year increase to total mineral reserves of approximately 170,000 tonnes of contained copper and 360,000 ounces of contained gold, after adjusting for 2020 mining depletion.

• Announced an updated Constancia mine plan resulting in an increase in average annual copper production to approximately 102,000 tonnes over the next eight years at an average cash cost of $1.18 per pound of copper produced, net of by-product credits.

• Announced an updated Lalor and Snow Lake mine plan resulting in an increase in annual gold production to over 180,000 ounces during the first six years of New Britannia's operation at an average cash cost of $412 per ounce of gold produced, net of by-product credits.

• Announced a significant new discovery at our Copper World properties adjacent to Rosemont on wholly-owned private land. Four deposits have been identified to date with a combined strike length of over five kilometres consisting of high-grade copper sulphide and oxide mineralization at shallow depth. The follow-up 2021 exploration program has been expanded to further test the potential for additional mineralization, develop an initial inferred resource estimate and complete a preliminary economic assessment. As a result, we have increased our 2021 spending on Copper World by approximately $24 million.

• Announced a preliminary economic assessment ("PEA") for our Mason copper project with a 27-year mine life and average annual copper production of approximately 140,000 tonnes over the first ten years of full production. The PEA indicates an after-tax net present value^3^ of $519 million and approximately 14% internal rate of return at $3.10 per pound copper, which increases to $773 million and approximately 15%, respectively, at $3.25 per pound copper.

• Issued $600.0 million of 4.5% senior notes due 2026 and redeemed all of our outstanding $600.0 million of 7.625% senior notes due 2025, thereby reducing our annual cash interest payments.

• On May 10, 2021, an amendment to the Constancia streaming agreement was signed with Wheaton Precious Metals ("Wheaton"). The amendment eliminates the requirement to deliver an additional 8,020 ounces of gold to Wheaton for not mining four million tonnes of ore from the Pampacancha deposit by June 30, 2021, while increasing the fixed gold recovery applied to Constancia ore processed during the reserve life of Pampacancha and introduces an additional potential future deposit of $4 million from Wheaton.

Summary of First Quarter Results

Cash generated from operating activities in the first quarter of 2021 increased to $51.8 million compared to $9.1 million in the same quarter of 2020. Operating cash flow before change in non-cash working capital was $90.7 million during the first quarter of 2021, reflecting an increase of $48.7 million compared to the same period of 2020. The increase in operating cash flow is primarily the result of higher realized metal prices and higher zinc sales volumes, partially offset by lower sales volumes of copper and precious metals.

Consolidated copper-equivalent production in the first quarter of 2021 decreased by 9% compared to the same period in 2020 primarily as a result of lower copper grades and a scheduled semi-annual mill maintenance shutdown at Constancia, partially offset by higher copper and gold grades and recoveries in Manitoba during the quarter.

Net loss and loss per share in the first quarter of 2021 were $60.1 million and $0.23, respectively, compared to a net loss and loss per share of $76.1 million and $0.29, respectively, in the first quarter of 2020. First quarter earnings benefited from higher realized prices for all metals, combined with higher sales volumes of zinc which was partially offset by lower sales volumes of copper and precious metals due to the timing of sales in Peru and a buildup of copper concentrate in Manitoba caused by limited railcar availability. First quarter results included a $12.5 million non-cash gain on the revaluation of the gold prepayment liability but were negatively impacted by charges related to the refinancing of the 2025 senior notes, including a non-cash write off of $49.8 million connected with the exercise of the redemption option, a call premium payment of $22.9 million and a non-cash expense of unamortized transaction costs of $2.5 million in relation to the 2025 notes that were redeemed. A variable consideration adjustment to deferred gold and silver revenue resulted in a net increase to revenue of $1.6 million.

Adjusted net loss^1^and adjusted net loss per share^1^ in the first quarter of 2021 were $16.1 million and $0.06 per share after adjusting for the finance charges and the net mark-to-market loss on financial instruments, among other items. This compares to an adjusted net loss and adjusted net loss per share of $39.3 million, and $0.15 per share in the same period of 2020. First quarter adjusted EBITDA^1^^^ was $104.2 million, compared to $55.0 million in the same period of 2020.

First quarter Peru sales were impacted by a 10,000 tonne shipment of copper concentrate valued at approximately $21 million for which a payment was received but did not meet the revenue recognition criteria due to the delayed timing of the shipment into early April. First quarter Manitoba sales were impacted by a delay in accessing additional railcars after a strong copper production quarter resulting in approximately 5,000 tonnes of copper concentrate inventory in excess of normal operating levels, valued at approximately $18 million. Had both parcels of copper concentrate been sold during the first quarter, we would have realized approximately $39 million of incremental revenue, assuming end of quarter commodity prices. The above quantities have been recognized as revenue in the second quarter of 2021. First quarter results were also negatively impacted by the realized copper price hedging of our provisionally priced copper sales.

As at March 31, 2021, our liquidity includes $310.6 million in cash and cash equivalents as well as undrawn availability of $293.9 million under our Credit Facilities. We expect that our current liquidity together with cash flows from operations will be sufficient to meet our liquidity needs for 2021.

All values are in US Dollars.

In the first quarter of 2021, consolidated cash cost per pound of copper produced, net of by-product credits^1^, was $1.04, compared to $0.98 in the same period in 2020. This increase was a result of higher Peru milling costs related to a scheduled January 2021 plant shutdown, thus resulting in lower production in Peru, and higher mining costs in Manitoba due to stockpiling of gold ore in preparation for the mid-year startup of New Britannia, partially offset by higher zinc by-product credits. We expect our consolidated cash cost per pound of copper produced, net of by-product credits to decline in subsequent quarters in line with our 2021 guidance.

Sustaining cash cost per pound of copper produced, net of by-product credits^1^ increased to $2.16 in the first quarter of 2021 from $2.05 in the same period in 2020 primarily due to the same reasons. Incorporating sustaining capital, capitalized exploration, royalties, selling, administrative and regional costs, consolidated all-in sustaining cash cost per pound of copper produced, net of by-product credits^1^, in the first quarter of 2021 was $2.37, which increased from $2.17 in the same period last year primarily due to the same reasons and higher corporate general and administrative costs due to higher stock-based compensation expense.

RECENT DEVELOPMENTS

COVID-19 Business Update

The COVID-19 pandemic continues to have a significant global impact as we mark the one-year anniversary of the global outbreak. Throughout this time, we have prioritized the health and safety of our people by adapting our processes and procedures based on the local situation and taking proactive measures to prevent or minimize the spread of COVID-19 within our workplaces.

As cases of COVID-19 remain elevated in Peru and continue to rise near our operations in Manitoba, we have experienced limited transmission at both of our operations. We have responded to these events quickly and have worked collaboratively with local health authorities to contain outbreaks while strengthening preventative measures at the workplace with negligible production or financial impacts. We believe we are appropriately enhancing our preventative and monitoring activities as the challenges of the pandemic evolve, but we remain at increased operational risk. We continue to monitor the risks of the pandemic at each of our locations to ensure the safety of our workforce, their families, and the communities in which we operate.

Increased Constancia Reserves and Updated Mine Plan

On March 29, 2021, we released an updated mine plan for our Constancia operations that reflects an increase in copper and gold production from 2022 to 2025 as the higher grades from the Pampacancha deposit enter the mine plan. The updated mine plan incorporates higher-grade reserves from the Constancia North pit extension, which contributed to an increase in reserves of 33 million tonnes at a grade of 0.48% copper and 0.115 grams per tonne gold and extends the higher grade profile to 2028. This resulted in an increase of approximately 11% in contained copper and 12% in contained gold over the prior year's reserves, after adjusting for mining depletion in 2020.

With the incorporation of Pampacancha and Constancia North, annual production at Constancia is expected to average approximately 102,000 tonnes of copper and 58,000 ounces of gold over the next eight years, an increase of 40% and 367%, respectively, from 2020 levels, which were partially impacted by an eight-week temporary mine interruption related to a government-declared state of emergency. Constancia's total copper and gold production increases by 12% and 9%, respectively, compared to the same period in the Company's previous technical report. Constancia maintains its low-cost profile with average cash cost and sustaining cash cost of $1.18 and $1.71, respectively, per pound of copper produced, net of by-product credits, over the next eight years.

New Britannia Mill Refurbishment Update and Snow Lake Updated Mine Plan

The New Britannia project continues to track ahead of the original schedule and is nearing completion with approximately 82% of the project completed at the end of April. Commissioning of the gold plant is expected in mid-2021 with first gold production expected early in the third quarter. The new copper flotation facility is on track for commissioning and ramp-up in the fourth quarter of 2021. Operational readiness activities are progressing as planned with underground development of Lalor's gold-rich lenses well-advanced in preparation for the start-up of New Britannia. We continue to see some COVID-related cost pressures on the project capital estimate at New Britannia.

On March 29, 2021, we announced that we have advanced the third phase of our Snow Lake gold strategy focusing on expansion and further optimization of operations. Various mining and milling optimization opportunities have been incorporated into an updated mine plan, which contemplates an increase in annual gold production from Lalor and the Snow Lake operations from approximately 150,000 ounces to over 180,000 ounces during the first six years of New Britannia's operation at cash cost and sustaining cash cost, net of by-product credits, of $412 and $788 per ounce of gold, respectively. Mineral reserves increased year-over-year, which resulted in no change to Snow Lake's mine life (to 2037) as we accelerated future reserves with a higher production rate at Lalor and Stall. This enhanced mine plan incorporates the results from several optimization initiatives, including:

• Early gold production at New Britannia expected in the third quarter of 2021, ahead of the original schedule;

• Increasing the Lalor mining rate to 5,300 tonnes per day from 4,500 tonnes per day in the previous mine plan, which is expected to begin after the 777 mine closes in mid-2022;

• Adding the 1901 deposit to the mine plan to include 1.58 million tonnes of reserves at a grade of 7.9% zinc, with production expected to commence in 2026 at a rate of approximately 1,000 tonnes per day;

• Higher throughput at Stall to achieve a rate of 3,800 tonnes per day compared to 3,500 tonnes per day in the previous mine plan; and

• Starting in 2023, increased copper and precious metal recoveries at Stall, where capital upgrades of $19 million are expected to increase Stall's copper recoveries to between 91% and 95%, gold recoveries to between 64% and 70%, and silver recoveries to between 65% and 74%, a significant increase from the assumed recoveries in the previous mine plan of 84% copper, 53% gold and 53% silver.

These mine plan enhancements optimize the processing capacity of the Snow Lake operations in a manner that maximizes the net present value of the operations. As a result of these initiatives, the production of gold, copper and silver are expected to increase by 18%, 35% and 27%, respectively, from 2022 to 2027 compared to the previous mine plan.

Pampacancha First Production Achieved

In early April 2021, the Company finalized the remaining land user agreement for Pampacancha and gained full access to the site to complete pit development activities. Blasting began in mid-April and first production from Pampacancha was achieved at the end of April, which is consistent with Hudbay's previous 2021 guidance and recently published mine plan. As a result of the completion of the individual land user agreements, revised growth capital expenditure guidance for Peru has increased to approximately $25 million in 2021.

Growing Near-term Production Outlook

On March 29, 2021, we announced our updated three-year production outlook. Consolidated copper and gold production are expected to increase to 129,500 tonnes and 280,000 ounces, respectively, in 2023, which represents an increase of 36% and 125%, respectively, from 2020 levels as we bring the Pampacancha and New Britannia projects into production. These growth projects more than offset the lost copper and gold production from 777 after its closure in mid-2022.

Rosemont Update

The appeal of the unprecedented Rosemont court decision with the U.S. Court of Appeals for the Ninth Circuit continues with a decision expected in the second half of 2021. In March 2021, the U.S. Army Corps of Engineers (the "Corps") granted an approved jurisdictional determination whereby the Corps determined there are no waters of the United States on the Rosemont property, and therefore, Rosemont does not require a Section 404 Water Permit.

Expanded Exploration Program at Copper World Discovery

On March 29, 2021, we announced the intersection of high-grade copper sulphide and oxide mineralization at shallow depth on our wholly-owned private land located within seven kilometres of our Rosemont copper project in Arizona. A 40,000-foot drill program was initiated in 2020 to confirm historical drilling in this past-producing copper region formerly known as Helvetia. After receiving encouraging initial results in February 2021, we launched a larger 70,000-foot drill program and increased the number of drill rigs at site to further test the four deposits at Copper World and the potential for additional mineralization.

Our 2020 drill program confirmed the discovery of the Broad Top Butte, Copper World, Peach and Elgin deposits, with a combined strike length of over five kilometres and opportunities to discover additional mineralization between the deposits. The program intersected significant volumes of high-grade copper sulphide and oxide mineralization starting, in most cases, near surface or at shallow depth. Drilling at Broad Top Butte included intersections of 440 feet of 1.38% copper and 246 feet of 0.70% copper starting at surface. Drilling at the Peach and Eglin deposits included intersections of 500 feet of 0.82% copper and 300 feet of 0.64% copper, both starting from surface. The mineralization at the Copper World deposits is located closer to surface than at Rosemont and remains open at depth.

Given the continued success from the Copper World exploration program, in April 2021, we increased the 2021 budget by approximately $24 million, which includes approximately $14 million for additional exploration expenditures and approximately $10 million of operational expenses related to further studies, none of which will be capitalized.

The additional exploration activities are expected to include resource definition drilling and testing targets on our private land. The additional studies relate to planned hydrogeological, geotechnical and other studies to potentially support future economic assessments and mine plans. Mineralogical studies and metallurgical testing have also been initiated and are expected to continue in the coming months. Geophysical surveys have been completed and are being analyzed to identify further targets on our private land package. Depending on the exploration program results, we expect to complete an initial inferred resource estimate before the end of the year and a preliminary economic assessment in the first half of 2022.

Increased Resource Estimate and Positive Preliminary Economic Assessment at Mason

The Mason project is our 100%-owned greenfield copper deposit located in the historic Yerington District of Nevada and is one of the largest undeveloped copper porphyry deposits in North America. In March 2021, we announced our first compiled resource estimate for the Mason project based on a resource model constructed using the same methods applied at Constancia. This resulted in a measured and indicated resource estimate of 2.2 billion tonnes at 0.29% copper, which increased from 1.4 billion tonnes at 0.32% copper previously.

The recently completed PEA contemplates a 27-year mine life with average annual copper production of approximately 140,000 tonnes over the first ten years of full production. The mine plan assumes the construction of a 120,000 tonnes per day conventional flotation concentrator and an initial capital cost estimate of approximately $2.1 billion. At a copper price of $3.10 per pound, the after-tax net present value using a 10% discount rate is $519 million and the internal rate of return is approximately 14%. The valuation metrics are highly sensitive to the copper price and at a price of $3.25 per pound, the after-tax net present value using a 10% discount rate increases to $773 million and the internal rate of return increases to approximately 15%.

There remain opportunities to further enhance the project economics through exploration for higher grade satellite deposits on our prospective land package in Nevada, including the Mason Valley properties. Much of the Mason Valley property is located on our wholly owned private lands and contains highly prospective skarn mineralization in an area that hosts several historical underground copper mines. Historical drilling and production records from the past producing mines at Mason Valley indicate the mineralization is high grade and starts at or near surface, similar to our Copper World property in Arizona. The Company expects to continue to compile and interpret historical data on its land package near Mason, to be followed by a geophysical survey to refine the exploration targets in preparation for a future drilling campaign.

Other Exploration Update

Constancia Regional Exploration

In addition to increasing Constancia's reserves, the Constancia North discovery also contributed to an improvement in the head grade of the Constancia mine mineral resource estimates: measured and indicated copper grades increased to 0.22% from 0.19% and inferred copper grades increased to 0.30% from 0.18%. A significant portion of the Constancia North resource estimate is classified as inferred due to wide drill spacing but there remains the opportunity to upgrade these inferred resources to a higher classification as we complete infill drilling. There also remains further opportunity to extend the Constancia North resources by incorporating steeply dipping high-grade skarn mineralization through a potential underground operation and a trade-off study between open pit versus underground development is expected to be completed in 2021. The mineralization remains open down plunge to the north.

We continue to advance regional exploration programs in Peru. In February 2021, we commenced drilling on the Quehuincha North high-grade skarn target located approximately 10 kilometres from Constancia, and drilling continues with five holes completed to-date. Discussions continue to progress with the community of Uchucarcco on the Maria Reyna and Caballito properties, both of which are located within ten kilometres of Constancia, and we expect to reach an agreement this year. We also expect to commence drilling activities at the Llaguen property in the coming weeks. Llaguen is a copper porphyry target located in northern Peru, near the city of Trujillo and in close proximity to existing infrastructure.

Snow Lake Regional Exploration

Exploration efforts at the Lalor mine in 2020 continued to be successful with the definition of an additional 1.8 million tonnes of mineral resources, increasing total inferred mineral resources at Lalor to 6.2 million tonnes. The inferred resources have the potential to extend the Lalor mine life beyond the current estimate of ten years and maintain the 5,300 tonnes per day production level beyond 2027.

Preliminary results from our 2021 winter drill program in the Chisel Basin in Snow Lake indicate that a potential copper-gold feeder zone to the 1901 deposit exists with one hole intersecting 11.6 metres at 2.7% copper and 3.4 grams per tonne gold, which is similar to the known geology at the Lalor deposit. A review is underway to determine next steps for exploration at 1901 and whether it will be best conducted from surface or from underground once development of the deposit has commenced and suitable drill platforms can be established. We also continue to test other targets within the Chisel Basin.

Senior Unsecured Notes Refinancing

On March 8, 2021, we completed the offering of $600.0 million aggregate principal amount of 4.5% senior notes due April 2026 (the "New Notes"). The New Notes are governed by an indenture, dated as of March 8, 2021, among the Company, the subsidiaries of the Company party thereto as guarantors and U.S. Bank National Association, as trustee.

The proceeds from this offering, together with available cash on hand, were used to redeem all $600.0 million of our outstanding 7.625% senior notes due 2025 (the "Redeemed Notes"), including the payment of accrued and unpaid interest and $31.0 million in net transaction and early redemption costs associated with the New Notes. The lower interest rate on the New Notes, versus the rate on the Redeemed Notes, will result in reduced cash interest payments of almost $19 million annually.

Collective Bargaining Agreements

The collective bargaining agreements with the unionized workforces at each of our Peru and Manitoba operations expired on or about December 31, 2020. We continue to advance the collective bargaining process with the labour unions in each jurisdiction as we work toward renewing the collective agreements.

Wheaton Agreement Amendment related to Pampacancha Delivery Obligation

On May 10, 2021, an amendment to the Constancia streaming agreement was signed with Wheaton. The amendment eliminates the requirement to deliver an additional 8,020 ounces of gold to Wheaton for not mining four million tonnes of ore from the Pampacancha deposit by June 30, 2021. As part of this amendment, Hudbay has agreed to increase the fixed gold recoveries that apply to Constancia ore production from 55% to 70% during the reserve life of Pampacancha, which matches the fixed rate of recovery that applies to Pampacancha production. In addition, if Hudbay mines and processes four million tonnes of ore from the Pampacancha deposit by December 31, 2021, Wheaton will make an additional deposit payment of $4 million.

The Constancia team continues to effectively operate in an environment of strict COVID-19 measures and controls. We continue to work collaboratively with the local health authorities to ensure our workforce and partners adhere to COVID-19 protocols while continuing to operate safely and efficiently. Full year production of all metals and unit operating costs at Constancia are on track to achieve the guidance ranges for 2021.

Ore mined at Constancia increased 11% in the first quarter of 2021 compared to the first quarter of 2020 resulting in a stockpile build up while managing the level of contaminants and hardness of the ore being sent to the mill. Furthermore, activity during the comparative 2020 period was impacted by a temporary suspension of operations at Constancia during the last two weeks of March 2020 following the government declared state of emergency in response to the COVID-19 pandemic.

Ore milled during the first quarter of 2021 was 5% lower compared to the same period in 2020 due to increased ore hardness that limited throughput as well as a scheduled semi-annual maintenance shutdown in January 2021 that did not occur in the prior period. Compared to the same period in 2020, milled gold grades in the first quarter significantly increased, by 33%, as we accessed higher grade ore from the deeper banks of the pit, while silver and copper grades declined by 9% and 3%, respectively. Copper recoveries in the first quarter of 2021 remained consistent with the same period in 2020.

Combined mine, mill and G&A unit operating costs in the first quarter of 2021 were 34% higher than the same period in 2020 and is higher than the upper end of our 2021 guidance range, primarily due to fewer tonnes of ore milled and increased operating costs related to the planned plant maintenance shutdown and enhanced COVID-19 protocols. Excluding COVID-related costs in Peru of $4.6 million, the unit operating costs in the first quarter were $11.74 per tonne. We expect full year operating costs to decline and be in line with the 2021 guidance range.

In the first quarter of 2021, production of copper and silver were 8%, and 12% lower, respectively, than the same period in 2020 due to lower ore grades and lower throughput. Molybdenum production in the first quarter of 2021 was lower than the same period in 2020 due to the same reasons as well as lower recoveries. Production of gold in the first quarter of 2021 was 51% higher than the same period in 2020 due to higher grades, partially offset by lower mill throughput.

Cash cost per pound of copper produced, net of by-product credits, for the three months ended March 31, 2021 was $1.82. Cash cost increased 28%, compared to the same period in 2020. The overall increase is primarily due to higher milling costs related to the planned plant maintenance shutdown, higher general and administrative costs due to higher COVID-19 related costs and lower copper production caused by lower throughput and lower copper grades as we progress through the mine plan.

Sustaining cash cost per pound of copper produced, net of by-product credits increased by 24% compared to the first quarter of 2020, mainly due to the same factors noted above affecting cash costs, with no meaningful change in sustaining capital expenditures.

Compared to the same period in 2020, quantities of payable metal sold for the three months ended March 31, 2021 for copper, silver and molybdenum were lower while gold was higher, primarily for the same reasons that affected contained metal production as well as the relative timing of shipments. First quarter sales were negatively impacted by a ten thousand tonne shipment of copper concentrate for which a payment was received but which did not otherwise meet the revenue recognition criteria. Revenue related to this transaction has been recorded in the second quarter of 2021.

The Manitoba business unit had stable operating performance across the mines, mills and zinc plant during the first quarter while facing increasing COVID-19 related logistical challenges. Late in 2020, we added new controls at the Snow Lake camp by introducing point of care PCR testing. Similar testing is being introduced in Flin Flon during the second quarter. COVID-19 vaccinations are currently being rolled out throughout the Snow Lake and Flin Flon communities and workforce. Full year production of all metals and unit operating costs in Manitoba are on track to achieve the guidance ranges for 2021.

Ore mined at our Manitoba operations during the first quarter of 2021 was generally in line with the same period in 2020. Copper and gold grades mined during the three months ended March 31, 2021 were 30% and 22% higher, respectively, compared to the same period in 2020, consistent with the life of mine production schedules at Lalor and 777 which includes mining out higher grade remnant stopes from 777 as it nears the end of its mine life. Silver and zinc grades mined during the three months ended March 31, 2021 were generally in line with the same period in 2020.

Development and underground construction activities continue in the lower part of the Lalor mine in order to ensure we maintain consistent gold and copper-gold production for the start-up and ongoing operation of the New Britannia mill, scheduled for early in the third quarter of 2021. As at the end of the first quarter, approximately 26,000 tonnes of gold ore had been stockpiled as initial feed for the New Britannia mill, up from 12,000 tonnes at the end of the fourth quarter of 2020. The incremental mining activity associated with growing the gold ore stockpile has contributed to elevated combined mine, mill and G&A unit operating costs during the first quarter of 2021. The gold ore stockpile is expected to continue to grow during the second quarter of 2021.

At 777, the focus is mining out the remaining reserves by executing the mine production sequence and completing the necessary ground rehabilitation in order to access old workings and remnant stopes.

Total unit operating costs for the mines during the first quarter of 2021 increased by 16% compared to the same period in 2020 mainly due to lower capitalized development at both Lalor and 777.

At the Stall concentrator, ore processed during the first quarter of 2021 was only 2% lower than the same period in 2020, despite an incremental 14,000 tonnes of Lalor gold ore being stockpiled during the quarter as initial feed for the New Britannia mill. Stall recoveries during the first quarter of 2021 were consistent with the metallurgical model. In early April, production at the Stall mill was suspended for four days as a precaution due to COVID related absenteeism. We do not expect any material impact to second quarter financial results related to the Stall mill production suspension.

Ore processed at the Flin Flon concentrator in the first quarter of 2021 decreased by 15% compared to the same period in 2020, as operations were negatively impacted at the end of March by the spring thaw and less Lalor ore being processed in Flin Flon in order to grow the gold ore stockpile as initial feed for the New Britannia mill. As a result of decreased milling in the first quarter of 2021, unit operating costs increased by 25% at the Flin Flon concentrator compared to the same period in 2020.

Recoveries of copper, gold and silver at the Flin Flon concentrator during the first quarter of 2021 were higher by 9%, 20% and 22%, respectively, compared to the same period in 2020 due to higher head grades from the mining out of higher grade remnant stopes at 777.

Combined mine, mill and G&A unit operating costs in the first quarter of 2021 increased by 19% compared to the same period in 2020, due to lower mill throughput as well higher unit operating costs at the mines for the reasons described above.

OUTLOOK

Peru has recently undergone a period of heightened political instability. A general presidential election was held on April 11, 2021 with a record number of candidates resulting in a runoff election expected to take place on June 6, 2021 between the top two candidates. The risk exists that, following the presidential election, the new government could make changes to the constitution or government policies that alter laws regulating the mining industry. A change in government, government policy, the declaration of a state of emergency or the implementation of new, or the modification of existing, laws and regulations affecting our operations and other mineral properties could have a material adverse impact on the outlook for our Constancia mine and the Pampacancha satellite deposit.

This outlook includes forward-looking information about our operations and financial expectations based on our expectations and outlook as of May 11, 2021. As a result of the COVID-19 global pandemic, we have experienced operational, supply chain, travel, labour and shipping disruptions, and we may continue to experience similar disruptions in the future. Given the uncertainty of the duration and magnitude of the impact of COVID-19 as well as the upcoming Peru presidential election in June 2021 and the corresponding risks described above, our 2021 production and cost guidance and three-year production guidance are subject to a higher-than-normal degree of uncertainty. The guidance below does not reflect any potential for additional suspensions or other significant disruption to operations or delays to development activities.

This outlook, including expected results and targets, is subject to various risks, uncertainties and assumptions, which may impact future performance and our achievement of the results and targets discussed in this section. For additional information on forward-looking information, refer to the "Forward-Looking Information" section of this MD&A. In addition to this section, refer to the "Operations Review" sections for additional details on our outlook for 2021.

^1^ Metal reported in concentrate is prior to treatment or refining losses or deductions associated with smelter terms.
^2^ Manitoba production guidance assumes the 777 mine is depleted at the end of the second quarter of 2022, resulting in lower copper and zinc production after its closure.

Using the mid-point of the guidance ranges, consolidated copper and gold production are expected to increase to 129,500 tonnes and 280,000 ounces, respectively, in 2023, which represents an increase of 36% and 125%, respectively, from 2020 levels as Hudbay brings online its Pampacancha and New Britannia growth projects. These growth projects more than offset the lost copper and gold production from 777 after its closure in mid-2022.

Peru's 2021 production guidance reflects the commencement of Pampacancha mining in the second quarter, with the initial phase of lower copper grades, but higher gold grades, expected to continue for the balance of the year before higher copper grades are forecast to enter the mine plan in 2022 and beyond.

Manitoba's 2021 production guidance reflects an increase in Lalor's mine throughput to 4,650 tonnes per day, from the previous 4,500 tonnes per day, as the recent trend of stronger production from the mine is expected to continue. Lalor's mine throughput is expected to further increase to 5,300 tonnes per day starting in 2023 due to technical and operational improvements and the allocation of mining resources from the 777 mine after its closure in 2022. Manitoba's 2023 production reflects higher copper, gold and silver recoveries at the Stall mill as a result of the implementation of various mill flowsheet enhancements in 2022.

FINANCIAL REVIEW

Financial Results

In the first quarter of 2021, we recorded a net loss of $60.1 million compared to a net loss of $76.1 million for the same period in 2020, representing an increase in profit of $16.0 million.

The following table provides further details on these variances:

Revenue

Revenue for the first quarter of 2021 was $313.6 million, $68.5 million higher than the same period in 2020, mainly due to higher realized metal prices as well as higher sales volumes of zinc and a higher relative variable consideration adjustment. Offsetting this increase were lower sales volumes of copper and precious metals due to lower Constancia throughput and a shipment of copper concentrate for which a payment was received as of March 31, 2021, but which did not otherwise meet the revenue recognition criteria.

Realized sales prices

This measure is intended to enable management and investors to understand the average realized price of metals sold to third parties in each reporting period. The average realized price per unit sold does not have any standardized meaning prescribed by IFRS, is unlikely to be comparable to similar measures presented by other issuers and should not be considered in isolation or a substitute for measures of performance prepared in accordance with IFRS.

For sales of copper, gold and silver we may enter into non-hedge derivatives ("QP hedges") which are intended to manage the provisional pricing risk arising from quotational period terms in concentrate sales agreements. The QP hedges are not removed from the calculation of realized prices. We expect that gains and losses on QP hedges will offset provisional pricing adjustments on concentrate sales contracts.

Our realized prices for the first quarter of 2021 and 2020, respectively, are summarized below:

^4^Sales of gold and silver from our 777 and Constancia mines are subject to our precious metals stream agreement with Wheaton Precious Metals, pursuant to which we recognize deferred revenue for precious metals deliveries and also receive cash payments. Stream sales are included within realized prices and their respective deferred revenue and cash payment rates can be found on page 29.

At March 31, 2021, the LME copper spot price increased by 14% compared to the fourth quarter of 2020. The first quarter realized copper price was 4% below the LME quarterly average price as certain hedges were entered into at copper prices below the monthly average copper price.

Total cost of sales for the first quarter of 2021 was $261.1 million, reflecting a decrease of $6.0 million from the first quarter of 2020. Cost of sales related to Peru decreased in the first quarter of 2021, compared to the same period of 2020, by $15.8 million. Compared to the same period in 2020, the decrease is primarily the result of lower relative changes in product inventory as well as a comparative period net realizable value of inventory adjustment and a reduction in depreciation and amortization. Partially offsetting these costs were higher milling costs related to the scheduled plant maintenance during the quarter and higher general and administrative costs mainly related to comparatively higher COVID-related costs. In Manitoba, cost of sales increased by $9.8 million, compared to the first quarter of 2020 as a result of higher mining costs partially offset by lower relative changes in product inventory related to a buildup of finished goods inventory during the quarter as a result of a lack of rail car availability.

For details on unit operating costs refer to the respective tables in the "Operations Review" section of this MD&A.

For the first quarter of 2021, other significant variances in expenses from operations, compared to the same period in 2020, include the following:

• Other operating expenses decreased by $8.8 million, compared to the same period in 2020 primarily due to a reversal of DRO expenses on non-producing properties in Manitoba as a result of increasing discount rates and a reduction in losses on disposal of property, plant and equipment in the current quarter.

• Selling and administrative expenses increased by $4.8 million compared to the same period in 2020. This increase was mainly due to higher stock-based compensation charges as a result of the relative impact of the revaluation of previously issued share units to higher share prices.

• Exploration and evaluation expenses increased by $1.3 million compared to the first quarter in 2020, as drilling programs in Arizona ramped up in the first quarter of 2021.

^3^Includes accretion on community agreements, unwinding of discount on provisions, and net foreign exchange losses (gains).

Compared to the three months ended March 31, 2020, net finance expense increased by $65.3 million due to a $40.0 million increase in non-cash finance costs as well as a $25.3 million increase in accrued finance costs both of which were primarily related to the refinancing of our 2025 senior notes. The early redemption of these notes in the current quarter resulted in a $49.8 million write off of the non-cash embedded derivative related to the exercise of the prepayment option, expensing of a call premium of $22.9 million and a write off of unamortized transaction costs of $2.5 million. Offsetting these expenses was a $12.5 million non-cash gain on the revaluation of the gold prepayment liability due to increasing discount rates and lower gold forward prices relative to the fourth quarter of 2020.

Tax Recovery

For the three months ended March 31, 2021, tax recovery increased by $4.1 million compared to the same period in 2020. The following table provides further details:

All values are in US Dollars.

Income Tax Recovery

Applying the estimated Canadian statutory income tax rate of 26.3% to our loss before taxes of $69.6 million for the first quarter in 2021 would have resulted in a tax recovery of approximately $18.3 million; however, we recorded an income tax recovery of $25.4 million. The significant items causing our effective income tax rate to be different than the 26.3% estimated Canadian statutory income tax rate include:

• Certain deductible temporary differences mostly with respect to Peru, and mostly relating to the decommissioning and restoration liabilities, were recognized as we have determined that it is probable that we will realize the recovery of these deferred tax assets based on the timing of the reversals of the deductible temporary differences and the future projected taxable profit of the Peruvian operations.  This has resulted in a deferred tax recovery of $8.9 million.

• Certain deductible temporary differences with respect to Manitoba, and mostly relating to the decommissioning and restoration liabilities, were not recognized as we have determined that it is not probable that we will realize the recovery of these deferred tax assets based on the timing of the reversals of the deductible temporary differences and the future projected taxable profit of the Manitoba operations. Adjusted for the average annual effective tax rate methodology, this resulted in deferred tax expense of $1.10 million.

Mining Tax Recovery

Applying the estimated Manitoba mining tax rate of 10.0% to our loss before taxes of $69.6 million for the first quarter in 2021 would have resulted in a tax recovery of approximately $7.0 million; however, we recorded a mining tax expense of $15.9 million. Effective mining tax rates can vary significantly based on the composition of our earnings and the expected amount of mining taxable profits. Corporate costs and other costs not related to mining operations are not deductible in computing mining profits. A brief description of how mining taxes are calculated in our various business units is discussed below.

Manitoba

The Province of Manitoba imposes mining tax on profit related to the sale of mineral products mined in the Province of Manitoba (mining taxable profit) at the following rates:

• 10% of total mining taxable profit if mining profit is C$50 million or less;

• 15% of total mining taxable profit if mining profits are between C$55 million and C$100 million; and

• 17% of total mining taxable profit if mining profits exceed C$105 million.

We estimate that the tax rate that will be applicable when temporary differences reverse will be approximately 10.0%.

Peru

The Peruvian government imposes two parallel mining tax regimes, the Special Mining Tax and the Modified Royalty, on companies' operating mining income on a sliding scale, with progressive rates ranging from 2.0% to 8.4% and 1.0% to 12.0%, respectively. Based on financial forecasts, we have recorded a deferred tax liability as at March 31, 2021, at the tax rate we expect to apply when temporary differences reverse.

LIQUIDITY AND CAPITAL RESOURCES

Senior Unsecured Notes Refinancing

On March 8, 2021, we completed the offering of $600.0 million aggregate principal amount of 4.5% senior notes due April 2026. The New Notes are governed by an indenture, dated as of March 8, 2021, among the Company, the subsidiaries of the Company party thereto as guarantors and U.S. Bank National Association, as trustee.

The proceeds from this offering, together with available cash on hand, were used to redeem all $600.0 million of our outstanding 7.625% senior unsecured notes due 2025, including the payment of accrued and unpaid interest, a call premium of $22.9 million on the Redeemed Notes, and to pay transaction costs associated with the New Notes. The lower interest rate on the New Notes, versus the rate on the Redeemed Notes, will result in reduced cash interest payments of almost $19 million annually.

Senior Secured Revolving Credit Facilities

We have two senior secured revolving credit facilities (the "Credit Facilities") for our Canadian and Peruvian businesses, with combined total availability of $400.0 million and substantially similar terms and conditions. As at March 31, 2021, our liquidity includes $310.6 million in cash and cash equivalents as well as undrawn availability of $293.9 million under our Credit Facilities. As at March 31, 2021, we were in compliance with our covenants under the Credit Facilities and had drawn $106.1 million in letters of credit under the Credit Facilities.

As at March 31, 2021, the Arizona business unit had $8.6 million in surety bonds issued to support future reclamation and closure obligations. The Peru business unit also had $85.0 million in letters of credit issued with various Peruvian financial institutions. No cash collateral is required to be posted under these letters of credit or surety bonds.

Financial Condition

Financial Condition as at March 31, 2021 compared to December 31, 2020

Cash and cash equivalents decreased by $128.6 million during the first quarter to $310.6 million as at March 31, 2021. This decrease was mainly the result of $83.0 million of capital investments primarily at our Peru and Manitoba operations, interest payments and other financing and leasing payments of $50.8 million and $44.3 million, respectively, and paid dividends of $2.1 million. Offsetting these cash outflows was cash flow from operating activities of $51.8 million. We hold the majority of our cash and cash equivalents in low-risk, liquid investments with major Canadian and Peruvian financial institutions.

Working capital decreased by $70.6 million to $236.3 million from December 31, 2020 to March 31, 2021, primarily due to the cash and cash equivalent decrease of $128.6 million and an increase of $30.6 million in other financial liabilities due to a partial reclassification of the gold prepayment liability to current, partially offset by a decrease in trade and other payables of $47.9 million arising mainly from timing of interest payments on our senior notes and an increase of $39.3 million in finished goods and stockpile inventories.

Cash Flows

The following table summarizes our cash flows for the three months ended March 31, 2021 and March 31, 2020:

(in $ thousands)	Three months ended
	Mar. 31,2021	Mar. 31,<br>2020
Operating cash flow before changes in non-cash working capital	90,656	41,951

Effect of movement in exchange rates on cash and cash equivalents	(1,065)	2,644
Decrease in cash and cash equivalents	(128,571)	(90,149)

Cash Flow from Operating Activities

Cash generated from operating activities was $51.8 million during the first quarter of 2021, an increase of $42.7 million compared with the same period in 2020. Operating cash flow before change in non-cash working capital was $90.7 million during the first quarter of 2021, reflecting an increase of $48.7 million compared to the first quarter of 2020. The increase in operating cash flow is primarily the result of higher realized prices for all metals, and higher zinc sales volume. This was partially offset by lower sales volumes of copper compared to the first quarter of 2020.

Cash Flow from Investing and Financing Activities

During the first quarter of 2021, we used $179.3 million in investing and financing activities, primarily driven by $83.0 million of capital expenditures, interest payments of $50.8 million, other financing payments of $34.5 million, capitalized lease payments of $9.8 million and dividends paid of $2.1 million.

All values are in US Dollars.

Sustaining capital expenditures in Manitoba for the three months ended March 31, 2021 were $20.9 million, a decrease of $2.9 million compared to the same period in 2020. The decrease was mainly due to a reduction in capital development at the 777 mine as it approaches the end of its mine life as well as less capital development at Lalor, partially offset by increased tailings stability costs as we continue to the next phase of the project plan. Sustaining capital expenditures in Peru for the three months ended March 31, 2021 were $12.9 million and were relatively consistent with the same period in 2020. Variances between the periods were mainly caused by higher mine maintenance and tailings management construction costs, partially offset by decreased capitalized stripping costs.

Growth capital expenditures in Manitoba of $42.0 million included significant spending for the New Britannia refurbishment project as construction of the new copper flotation building and construction of a concentrate/tailings pipeline between the New Britannia and Stall mills nears completion. The project was approximately 82% complete at the end of April and is tracking ahead of the original schedule.

Growth capital expenditures in Peru of $19.9 million included costs associated with the individual agreements related to current uses of the land by certain community members as well as civil works related to the development of Pampacancha. As previously disclosed, the Company's growth capital guidance for Peru of $5.0 million did not include the cost of the individual land user agreements due to the ongoing nature of the negotiations. In early April 2021, the Company finalized the remaining land user agreement for Pampacancha and gained full access to the site to begin pit development activities. Blasting began in mid-April and development activities are well-advanced given the progress made on pre-development activities since January. First production from Pampacancha was achieved at the end of April, which is consistent with Hudbay's previous 2021 guidance and recently published mine plan disclosure. As a result of the completion of the individual land user agreements, revised growth capital expenditures guidance for Peru is expected to be approximately $24 million in 2021.

Other capitalized costs for the three months March 31, 2021 were negative $63.5 million and relate primarily to the remeasurement of previously recognized decommissioning and restoration liabilities at our Peru and Manitoba operations as a result of higher discount rates, which reduce the overall liability and the corresponding property, plant and equipment decommissioning assets.

Capital Commitments

As at March 31, 2021, we had outstanding capital commitments in Canada of approximately $52.0 million of which $49.8 million can be terminated, approximately $42.4 million in Peru primarily related to exploration option agreements, all of which can be terminated, and approximately $179.6 million in Arizona, primarily related to our Rosemont project, of which approximately $89.3 million can be terminated.

2 Operating cash flow before changes in non-cash working capital.

All values are in US Dollars.

Lower revenues in the first quarter of 2021 compared to the fourth quarter of 2020 were a function of lower sales volumes of copper from Peru due to lower throughput and grades and a delayed shipment for which revenue could not be recognized, and lower sales volumes from Manitoba related to a buildup of finished goods inventory during the quarter as a result of a lack of rail car availability. Results were negatively impacted by $75.2 million of various finance expenses related to the issuance of New Notes and a simultaneous early redemption of our Redeemed Notes. Increasing metal prices since March 2020 has resulted in steadily increasing gross profit and operating cash flows over the last four quarters.

The year 2020 saw increasing commodity prices after an initial sharp decline into mid-March with the onset of the COVID-19 pandemic. An eight-week suspension of Constancia operations in Peru due to a government declared state of emergency during the first half of 2020 and a six-week production interruption at the 777 mine during the fourth quarter of 2020 impacted our production and sales volumes for the full year; however, the shift in sales from Constancia to the second half of 2020 allowed us to benefit from the increasing commodity prices. The reduced copper production from Constancia and 777 was partially offset by increased production from Lalor.

Earnings in the fourth quarter of 2020 were negatively impacted by the 777 production interruption which resulted in $11.7 million in certain overhead costs being expensed. Earnings in the second quarter of 2020 were impacted by the temporary suspension of operations at Constancia, which resulted in $25.6 million in certain overhead costs being expensed.

NON-IFRS FINANCIAL PERFORMANCE MEASURES

Adjusted net earnings (loss), adjusted net earnings (loss) per share, adjusted EBITDA, net debt, cash cost, sustaining and all-in sustaining cash cost per pound of copper produced, cash cost and sustaining cash cost per pound of zinc produced and combined unit cost and zinc plant unit cost are non-IFRS performance measures. These measures do not have a meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other issuers. These measures should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS and are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. Other companies may calculate these measures differently.

Management believes adjusted net earnings (loss) and adjusted net earnings (loss) per share better reflect the Company's performance for the current period and are better indications of its expected performance in future periods. These measures are used internally by the Company to evaluate the performance of its underlying operations and to assist with its planning and forecasting of future operating results. As such, the Company believes these measures are useful to investors in assessing the Company's underlying performance. We provide adjusted EBITDA to help users analyze our results and to provide additional information about our ongoing cash generating potential in order to assess our capacity to service and repay debt, carry out investments and cover working capital needs. Net debt is shown because it is a performance measure used by the Company to assess our financial position. Cash cost, sustaining and all-in sustaining cash cost per pound of copper produced are shown because we believe they help investors and management assess the performance of our operations, including the margin generated by the operations and the Company. Cash cost and sustaining cash cost per pound of zinc produced are shown because we believe they help investors and management assess the performance of our Manitoba operations. Combined unit cost and zinc plant unit cost is shown because we believe they help investors and management assess our cost structure and margins that are not impacted by variability in by-product commodity prices.

In the first half of 2020, a government-imposed shutdown of non-essential businesses led to a temporary suspension of our Constancia mining operations. Similarly, in the fourth quarter of 2020, a shaft incident led to a production interruption at 777 in Manitoba. Fixed overhead production costs incurred during these temporary production disruptions were directly charged to cost of sales. These costs did not contribute to production of inventory and were therefore excluded from the calculations of adjusted net earnings (loss), adjusted EBITDA and cash costs.

Adjusted Net Earnings (Loss)

Adjusted net earnings (loss) represents net earnings (loss) excluding certain impacts, net of taxes, such as mark-to-market adjustments, impairment charges and reversal of impairment charges, write-down of assets, and foreign exchange (gain) loss. These measures are not necessarily indicative of net earnings (loss) or cash flows as determined under IFRS.

The following table provides a reconciliation of earnings (loss) per the consolidated interim income statements, to adjusted net earnings (loss) for the three months ended March 31, 2021 and 2020.

After adjusting reported net loss for those items not considered representative of the Company's core business or indicative of future operations, the Company had an adjusted net loss in the first quarter 2021 of $16.1 million or $0.06 loss per share.

Adjusted EBITDA

Adjusted EBITDA is profit or loss before net finance expense/income, tax expense/recoveries, depreciation and amortization of property, plant and equipment and deferred revenue, as well as certain other adjustments. We calculate adjusted EBITDA by excluding certain adjustments included within our adjusted net earnings measure which we believe reflects the underlying performance of our core operating activities. The measure also removes the impact of non-cash items and financing costs that are not associated with measuring the underlying performance of our operations. However, our adjusted EBITDA is not the measure defined as EBITDA under our senior notes or revolving credit facilities and may not be comparable with performance measures with the same name reported by other companies. Adjusted EBITDA should not be considered as a substitute for profit or loss or as a better measure of liquidity than operating cash flow, which are calculated in accordance with IFRS. We provide adjusted EBITDA to help users analyze our results and to provide additional information about our ongoing cash generating potential in order to assess our capacity to service and repay debt, carry out investments and cover working capital needs.

The following table presents the reconciliation of earnings (loss) per the consolidated interim income statements, to adjusted EBITDA for the three months ended March 31, 2021 and 2020:

Cash Cost, Sustaining and All-in Sustaining Cash Cost (Copper Basis)

Cash cost per pound of copper produced ("cash cost") is a non-IFRS measure that management uses as a key performance indicator to assess the performance of our operations. Our calculation designates copper as our primary metal of production as it has been the largest component of revenues. The calculation is presented in four manners:

• Cash cost, before by-product credits - This measure is gross of by-product revenues and is a function of the efforts and costs incurred to mine and process all ore mined. However, the measure divides this aggregate cost over only pounds of copper produced, our primary metal of production. This measure is generally less volatile from period to period, as it is not affected by changes in the price received for by-product metals. It is, however, significantly affected by the relative mix of copper concentrate and finished zinc production, where the sale of the zinc will occur later, and an increase in production of zinc metal will tend to result in an increase in cash cost under this measure.

• Cash cost, net of by-product credits - In order to calculate the net cost to produce and sell copper, the net of by-product credits measure subtracts the revenues realized from the sale of the metals other than copper. The by-product revenues from zinc, gold, and silver are significant and are integral to the economics of our operations. The economics that support our decision to produce and sell copper would be different if we did not receive revenues from the other significant metals being extracted and processed. This measure provides management and investors with an indication of the minimum copper price consistent with positive operating margins, assuming realized by-product metal prices are consistent with those prevailing during the reporting period. It also serves as an important operating statistic that management and investors utilize to measure our operating performance versus that of our competitors. However, it is important to understand that if by-product metal prices decline alongside copper prices, the cash cost net of by-product credits would increase, requiring a higher copper price than that reported to maintain positive cash flows and operating margins.

• Sustaining cash cost, net of by-product credits - This measure is an extension of cash cost that includes cash sustaining capital expenditures, including payments on capitalized leases, capitalized sustaining exploration, net smelter returns royalties, payments on certain long-term community agreements, as well as accretion and amortization for expected decommissioning activities for producing assets. It does not include corporate selling and administrative expenses. It provides a more fulsome measurement of the cost of sustaining production than cash cost, which is focused on operating costs only.

- All-in sustaining cash cost, net of by-product credits - This measure is an extension of sustaining cash cost that includes corporate G&A, regional costs, accretion and amortization for community agreements relating to current operations, and accretion for expected decommissioning activities for non-producing assets. Due to the inclusion of corporate selling and administrative expenses, all-in sustaining cash cost is presented on a consolidated basis only.

The tables below present a detailed build-up of cash cost and sustaining cash cost, net of by-product credits, by business unit in addition to consolidated all-in sustaining cash cost, net of by-product credits, and reconciliations between cash cost, net of by-product credits, to the most comparable IFRS measures of cost of sales for the three months ended March 31, 2021 and 2020. Cash cost, net of by-product credits may not calculate exactly based on amounts presented in the tables below due to rounding.

Zinc Cash Cost and Zinc Sustaining Cash Cost

Cash cost per pound of zinc produced ("zinc cash cost") is a non-IFRS measure that management uses as a key performance indicator to assess the performance of our Manitoba operations. This alternative cash cost calculation designates zinc as the primary metal of production as it is the largest component of revenues for our Manitoba business unit and should therefore be less volatile over time than Manitoba cash cost per pound of copper. The calculation is presented in three manners:

• Zinc cash cost, before by-product credits - This measure is gross of by-product revenues and is a function of the efforts and costs incurred to mine and process all ore mined. However, the measure divides this aggregate cost over only pounds of zinc produced, our primary metal of production. This measure is generally less volatile from period to period, as it is not affected by changes in the price received for by-product metals. It is, however, significantly affected by the relative mix of copper concentrate and finished zinc production, where the sale of the copper will occur later, and an increase in production of copper metal will tend to result in an increase in zinc cash cost under this measure.

• Zinc cash cost, net of by-product credits - In order to calculate the net cost to produce and sell zinc, the net of by-product credits measure subtracts the revenues realized from the sale of the metals other than zinc. The by-product revenues from copper, gold, and silver are significant and are integral to the economics of our Manitoba operation. The economics that support our decision to produce and sell zinc would be different if we did not receive revenues from the other significant metals being extracted and processed. This measure provides management and investors with an indication of the minimum zinc price consistent with positive operating margins, assuming realized by-product metal prices are consistent with those prevailing during the reporting period. It also serves as an important operating statistic that management and investors utilize to measure our operating performance at our Manitoba operation versus that of our competitors. However, it is important to understand that if by-product metal prices decline alongside zinc prices, the zinc cash cost net of by-product credits would increase, requiring a higher zinc price than that reported to maintain positive cash flows and operating margins.

• Zinc sustaining cash cost, net of by-product credits - This measure is an extension of zinc cash cost that includes cash sustaining capital expenditures, capitalized exploration, net smelter returns royalties, as well as accretion and amortization for expected decommissioning activities for producing assets. It does not include corporate selling and administrative expenses. It provides a more fulsome measurement of the cost of sustaining production than zinc cash cost, which is focused on operating costs only.

The tables below present a detailed build-up of zinc cash cost and zinc sustaining cash cost, net of by-product credits, for the Manitoba business unit, and reconciliations between zinc cash cost, net of by-product credits, to the most comparable IFRS measures of cost of sales for the three months ended March 31, 2021 and 2020. Zinc cash cost, net of by-product credits, may not calculate exactly based on amounts presented in the tables below due to rounding.

Combined Unit Cost & Zinc Plant Unit Cost Reconciliation

Combined unit cost ("unit cost") and zinc plant unit cost is a non-IFRS measure that management uses as a key performance indicator to assess the performance of our mining and milling operations. Combined unit cost and zinc plant unit cost are calculated by dividing the cost of sales by mill throughput and refined zinc metal produced, respectively. This measure is utilized by management and investors to assess our cost structure and margins and compare it to similar information provided by other companies in our industry. Unlike cash cost, this measure is not impacted by variability in by-product commodity prices since there are no by-product deductions; costs associated with profit-sharing and similar costs are excluded because of their correlation to external metal prices. In addition, the unit costs are reported in the functional currency of the operation which minimizes the impact of foreign currency fluctuations. In all, the unit cost measures provide an alternative perspective on operating cost performance with minimal impact from external market prices. In the first half of 2020, as a result of the temporary suspension of operations in Peru, fixed overhead production costs incurred during the suspension were directly charged to cost of sales. These costs did not contribute to production of inventory and were therefore excluded from the calculation of combined unit costs.

The tables below present a detailed combined unit cost and zinc plant unit costs for the Manitoba business unit and combined unit cost for the Peru business unit, and reconciliations between these measures to the most comparable IFRS measures of cost of sales for the three months ended March 31, 2021 and 2020.

ACCOUNTING CHANGES AND CRITICAL ESTIMATES

New standards and interpretations adopted

As of January 1, 2021, we have adopted an amendment to IAS 16, Property, Plant and Equipment ("IAS 16").

For information on new standards and interpretations adopted, refer to note 4 of our March 31, 2021 consolidated interim financial statements.

Estimates and judgements

The preparation of the consolidated interim financial statements in conformity with IFRS requires us to make judgements, estimates and assumptions that affect the application of accounting policies, reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated interim financial statements, and reported amounts of revenue and expenses during the reporting period. Actual results may differ from these estimates.

We review these estimates and underlying assumptions on an ongoing basis based on our experience and other factors, including expectations of future events that we believe to be reasonable under the circumstances. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. Certain accounting estimates and judgements have been identified as being "critical" to the presentation of our financial condition and results of operations because they require us to make subjective and/or complex judgments about matters that are inherently uncertain; or there is a reasonable likelihood that materially different amounts could be reported under different conditions or using different assumptions and estimates.

For more information on judgements and estimates, refer to note 2 of our March 31, 2021 consolidated interim financial statements.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

Management is responsible for establishing and maintaining adequate internal control over financial reporting ("ICFR"). ICFR is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS.

We did not make any changes to ICFR during the three months ended March 31, 2021 that materially affected or are reasonably likely to materially affect our ICFR.
