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 and nine months ended September 30, 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 September 30, 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, silver/gold doré 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 November 3, 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 and nine months ended September 30, 2021 and 2020

(b) 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 5c, 7 and 10 for further details on the impact of this change in estimation method.

During the current year, 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 year, the inflation rate estimate used to calculate DRO has been prospectively revised. Please see notes 5e and 16 for further details on the impact of this change in estimation method. In addition, an updated environmental provision following from a revised closure plan for the Flin Flon operation in Manitoba was completed and contains a number of estimates pertaining to cost, scope and timing of remediation work.

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, except for the new standards noted in Note 4.

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 and nine months ended September 30, 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.

As at September 30, 2021, Hudbay has not entered into any new contracts or contract modifications that are dependent on the LIBOR rate.

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 and nine months ended September 30, 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 catch up adjustment is made for all prior year stream revenues since the stream agreement inception date.

The variable consideration adjustment for the three and nine months ended September 30, 2020 resulted in an increase of revenue of $9,482 and $6,668, respectively. This increase in revenue was primarily the result of updates to the 777 mine plan resulting in the mining of fewer inferred resources than what was planned previously.

In the second quarter of 2021, the Company finalized an amendment with Wheaton Precious Metals ("Wheaton") related to the Peru stream agreement. The result of the amendment was a revision to the Peru gold and silver deferred revenue amortization rates and the related significant financing component. For further details refer to note 15.

(b) Mine operating costs

During the third quarter of 2021, Hudbay recognized a non-cash write-down of materials and supplies inventories of $5,445 and a past service cost provision adjustment related to pensions for unionized employees of $4,229.

(c) Depreciation and amortization

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

		Three months ended<br>September 30,				Nine months ended<br>September 30,
		2021		2020		2021		2020
Cost of sales	$	86,010	$	95,998	$	267,997	$	263,244
Selling and administrative expenses		441		467		1,403		1,308
	$	86,451	$	96,465	$	269,400	$	264,552

Effective January 1, 2021, the Company made a change in estimate in Peru for certain mineral property PP&E assets to utilize contained metal in the depreciation calculation. This better reflects the systematic allocation of costs to inventory given the change in grade profile following the recently published NI 43-101. For the three and nine months ended September 30, 2021, depreciation expense is higher by $2,046 and by $1,531, respectively, 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 as a change in estimate and applied prospectively. Please see Note 10 for further details.

Due to rising risk-free interest rates during the first nine months of 2021, discount rates used in the normal course revaluation of the DRO 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 loss of $134 and gain of $4,890 for the three and nine months ended September 30, 2021 respectively.

During the third quarter of 2021, there were costs incurred related to the restructuring of the Manitoba operations in preparation for the closure of 777 mine of $3,639. These costs were related to severance packages for unionized employees.

Other expenses primarily relates to other Arizona project costs (Copper World) that are not associated with Rosemont.

(g) Impairment - Environmental Obligation

During the third quarter of 2021, an impairment indicator was identified in relation to a revised Flin Flon closure plan. The revised closure plan, reflecting higher cost estimates, led to a large increase in the environmental obligation (note 16) and a corresponding increase to Flin Flon PP&E. The increase in Flin Flon PP&E prompted an impairment test of these assets since the Flin Flon operation is expected to close mid-2022. Hudbay recorded an impairment to PP&E by comparing the carrying value of the Flin Flon operation to its recoverable amount using the value-in-use method for future cash flows associated with the operation until closure. The value-in-use recoverable amount is considered a level 3 valuation method. This resulted in an impairment loss of $147,305. Given the closure is expected to occur in less than 12 months, future adjustments to the Flin Flon environmental provision from fair value adjustments, or otherwise, may lead to future impairment tests of the Flin Flon operation and any resulting impairments or impairment reversals will be charged to the income statement.

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 and nine months ended September 30, 2021 and 2020

During the three and nine months ended September 30, 2021, Hudbay recognized a recovery of nil and recovery of $1,446 in cost of sales related to adjustments of the carrying value of Peru inventories to net realizable value (three and nine months ended September 30, 2020 - nil and an expense of $2,221, respectively). Adjustments to the carrying value of inventories to net realizable value were related to changes in commodity prices.

Due to the upcoming closure of the Flin Flon operation, certain long term inventory supplies which are not expected to be utilized were written down and $5,445 was charged to mine operating costs in the third quarter of 2021 (note 5b).

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 of 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 costs 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 nine months ended September 30, 2021, as a result of the change in allocation, stockpile inventories have declined by $5,071 and finished goods inventories have increased by $642.

The derivative assets include derivative and hedging transactions. Derivative assets are carried at their fair value with changes in fair value recorded to the condensed consolidated income statements. The fair value adjustments for hedging type derivatives are recorded in revenue.

Investments at fair value through profit or loss consist of securities in Canadian metals and mining companies, all of which are publicly traded. The change in investments at fair value through profit or loss is mostly attributed to fluctuations in market price and foreign exchange impact.

9. Intangibles and other assets

Intangibles and other assets of $19,659 (December 31, 2020 - $21,173) includes $14,094 of other assets (December 31, 2020 - $15,764) and $5,565 of intangibles (December 31, 2020 - $5,409).

Other assets represent the carrying value of certain future community costs. The liability remaining for these agreements is recorded in other financial liabilities at amortized cost (note 12). Amortization of the carrying amount is recorded in the condensed consolidated interim income statements within other expenses (income) (note 5e). Intangibles mainly represent computer software costs.

For the nine months ended September 30, 2021, the increase in property, plant and equipment (cost) of $251,242 was mainly caused by fixed asset and construction in progress asset additions of $315,128, partially offset by net decreases in decommissioning and restoration assets of $48,902 (producing assets) mostly as a result of changes in discount rates associated with remeasurement of the liabilities. During the third quarter of 2021, there was a write-down of $5.4 million related to New Britannia assets that were not utilized as part of the project (note 5e). In addition, during the third quarter of 2021, a revised Flin Flon closure plan led to a large increase in the environmental obligation (note 16) and a corresponding increase to Flin Flon PP&E. A resulting impairment indicator was identified due to the limited life of the Flin Flon operation resulting in an impairment loss of $147,305 (note 5g).

Effective January 1, 2021, following a new NI 43-101 technical report for Peru, the Company made a change in estimate for the depreciation calculation of certain mineral property PP&E assets in Peru to utilize contained metal. This better reflects the systematic allocation of costs to inventory given the change in grade profile following the recently published NI 43-101.

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 three months ended September 30, 2021, depreciation expense is higher by $2,046 and for the nine months ended September 30, 2021 is higher by $1,531 to the result under the previous depreciation calculation.

The fair value adjustments for hedging type derivatives are recorded in revenue. Fair value adjustments for embedded derivatives are recorded within net finance expense.

As part of the streaming agreement for the 777 mine, Hudbay must repay, with precious metals credits, the deposit by August 1, 2052, the expiry date of the agreement. If the stream deposit is not fully repaid with precious metals credits from 777 production by the expiry date, a payment for the remaining amount will be due at the expiry date of the agreement. Given revised resource estimates and the planned closure of the 777 mine in 2022, Hudbay believes such a payment is expected and as such, as at September 30, 2021 the estimated repayment amount was reclassified to a refund liability. This will be discounted at the 9.0% rate inherent in the original agreement and accreted over the remaining term of the agreement.

On May 7, 2020, the Company entered into an agreement and received $115,005 in exchange for the delivery of 79,954 gold ounces starting January 2022 and ending in December 2023, which were valued at gold forward curve prices averaging $1,682 per ounce at the time of the transaction. The agreement has been assessed as a financial liability that has been designated as fair value through profit or loss within change in fair value of financial instruments, with a component of the fair value related to the fluctuation in the Company's own credit risk being recorded to other comprehensive income. The pre-tax fair value adjustment recorded in profit or loss and other comprehensive income for the three and nine months ended September 30, 2021 totaled a net loss of $435 and net gain of $3,974, respectively (three and nine months ended September 30, 2020 - net losses of $8,960 and $17,289, respectively).

Other financial liabilities at amortized cost relate to agreements with communities near the Constancia operation which allow Hudbay to extract minerals over the useful life of the Constancia operation, carry out exploration and evaluation activities in the area and provide Hudbay with community support to operate in the region. The changes in other financial liabilities at amortized cost during the three and nine months ended September 30, 2021 primarily relates to the execution of the remaining land user agreements with certain community members, partially offset by disbursements.

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 2.80% to 5.99%, 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 an 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 September 30, 2021 and September 30, 2020, relating to leases for which a recognition exemption was applied.

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 5f).

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 5f).

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").

Hudbay used the proceeds of the offering to satisfy and discharge all of its obligations with respect to its then outstanding $400,000 aggregate principal amount of 7.25% senior unsecured notes due 2023 (the "2023 Notes").

In 2020, the unamortized transaction costs of $2,315 were expensed upon extinguishment of the 2023 Notes. The early redemption of these notes resulted in a charge of $7,252, which was recorded on the condensed consolidated interim income statements.

As at September 30, 2021, $1,200,000 aggregate principal amount of senior notes were outstanding in two series: (i) a series of 4.50% senior notes due 2026 in an aggregate principal amount of $600,000 and (ii) a series of 6.125% senior notes due 2029 in an aggregate principal amount of $600,000.

15. Deferred revenue

On August 8, 2012 and November 4, 2013, Hudbay entered into precious metals stream transactions with 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 Peru's production.

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/Pampacancha life-of-mine plans. 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.

777 Stream Agreement

For the three and nine months ended September 30, 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 - CA$1,589 and CA$30.63 per ounce, respectively).

As part of the streaming agreement for the 777 mine, Hudbay must repay, with precious metals credits, the stream deposit by August 1, 2052, the expiry date of the agreement. If the stream deposit is not fully repaid with precious metals credits from 777 production by the expiry date, a payment for the remaining amount will be due at the expiry date of the agreement. Given the remaining mine life is less than 12 months, Hudbay estimates that a portion of the stream deposit will not be repaid by means of precious metals credits from 777 production. As at September 30, 2021, the estimated repayment amount was reclassified to a refund liability (note 12), which will be discounted at the 9.0% rate inherent in the original 777 stream agreement and accreted over the remaining term of the agreement.

Peru Stream Agreement

During the second quarter of 2021, an amendment to the Peru gold stream 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 recovery rate that applies to Pampacancha production. As such, Hudbay revised its estimate of the remaining number of gold ounces expected to be delivered under the Peru streaming arrangement. Based on the nature of the amendment to the streaming agreement, it was determined that this contract modification should be treated as a termination of the existing contract and creation of a new contract. The accounting for such a modification is fully prospective.

As a result of the contract modification, the transaction price has been redetermined and the discount rate used to compute the significant financing component has been reassessed as of May 1, 2021. Under IFRS 15, the significant financing component is recognized as a financing charge at each reporting period and grosses up the deferred revenue balance to recognize the significant financing element that is inherent in the contract. Discount rates are significantly lower than compared to when the original contract was initiated which has resulted in lower amortized revenues and lower interest accretion expense.

Effective May 1, 2021, the drawdown rate for the Peru stream agreement for gold was $762 per ounce and prior to May 1, 2021 the drawdown rate for gold was $990 per ounce (year ended December 31, 2020 - $976 per ounce). Effective May 1, 2021 the drawdown rate for the Peru stream agreement for silver was $15.64 per ounce and prior to May 1, 2021 the drawdown rate for silver was $21.86 per ounce (year ended December 31, 2020 - $21.52 per ounce).

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 nine months ended September 30, 2021.

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. This variable consideration adjustment resulted in an increase in revenue of $6,668 and reversal of finance expense of $3,692 for the year ended December 31, 2020.

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

		Sep. 30, 2021		Dec. 31, 2020

	$	343,132	$	8,719	$	10,449	$	2,030	$	1,144	$	365,474

The other category mainly consists of restructuring provisions related to the closure of the Flin Flon operations and other miscellaneous obligations primarily in the Arizona business unit.

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

Balance, December 31, 2020	$	343,132
Net increase in provisions		129,330
Disbursements		(16,479	)
Effect of change in estimate to inflation rates^1^		9,609
Unwinding of discounts (note 5f)		3,123
Effect of change in nominal discount rate		(46,365	)
Effect of foreign exchange		864
Balance, September 30, 2021	$	423,214

^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 third quarter of 2021, following a comprehensive update to the Flin Flon closure plan, additional provisions were recognized to reflect higher estimates for closure activities in Flin Flon through to the year 2122. The increase in the environmental obligation resulted in a corresponding increase in the Flin Flon PP&E. However, as the closure of Flin Flon is expected to commence within 12 months, an impairment indicator was identified which led to an impairment loss of $147,305 (note 5g).

During the first quarter of 2021, 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, since the first quarter of 2021, the inflation rate estimate used to calculate DRO has been prospectively revised.

19. Earnings per share

	Three months ended<br>September 30,		Nine months ended<br>September 30,

Basic and diluted weighted average common shares outstanding	261,517,461	261,272,151	261,430,996	261,272,151

The determination of the diluted weighted-average number of common shares excludes the impact of 496,558 weighted-average stock options outstanding that were anti-dilutive for the three and nine months ended September 30, 2021 (three and nine months ended September 30, 2020 - 1,574,357 and 1,506,625).

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 and nine months ended September 30, 2021, and Hudbay calculated diluted loss per share using 261,517,461 and 261,430,996, respectively (three and nine months ended September 30, 2020 - 261,272,151 common shares).

^1^Cash, 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 nine months ended September 30, 2021 was a loss of $2,311 (year ended December 31, 2020 was a loss of $1,885). ^10^ Discounted value based on a market rate consistent with the applicable Wheaton contract (note 12).

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 nine months ended September 30, 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 September 30, 2021, Hudbay had 59.1 million pounds of net copper swaps outstanding at an effective average price of $4.26/lb and settling across October 2021 to January 2022. 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 September 30, 2021 was an asset of $12,436 (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 September 30, 2021, Hudbay held contracts for forward zinc purchased of 1.2 million pounds (December 31, 2020 - 3.5 million pounds) that related to forward customer sales of zinc. Prices range from $1.09/lb to $1.38/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 September 30, 2021 was a net asset position of $196 (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.

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 and nine months ended September 30, 2021 and 2020

As at September 30, 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	Sep. 30, 2021	Dec. 31, 2020	Sep. 30, 2021
	pounds
Copper	(in thousands)	61,211	47,901	4.06
Gold	oz	24,980	18,106	1,756
Silver	oz	98,212	123,380	22.03

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 September 30, 2021, was an asset position of $15,812 (December 31, 2020 - an asset position of $21,295).

(d) Embedded derivatives

Prepayment option embedded derivative

The senior unsecured notes (note 14) may contain prepayment options, which represent embedded derivatives that may require bifurcation from the host contract. When bifurcation is required, the embedded derivatives are measured at fair value, with changes in the fair value being recognized as change in fair value of financial instruments on the income statement (note 5f). Neither the 2026 Notes nor the 2029 Notes contain embedded derivatives that require bifurcation from the host contract. The fair value of the embedded derivative at September 30, 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 financial liability at September 30, 2021 was a liability of $133,056 (December 31, 2020 - $137,031).

(c) Non-cash transactions:

During the nine months ended September 30, 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:

24. Events after the reporting period

Amendments to Credit Facilities

On October 26, 2021, the Company amended and restated its senior secured revolving credit facilities to increase the total amount of available borrowings to $450 million, eliminate certain financial covenants and amend others to increase its financial flexibility, reduce the effective interest rate and extend the maturity to October 26, 2025. The remaining financial covenants include maintaining a net debt to EBITDA ratio of less than 4.00:1, a senior secured debt to EBITDA of less than 3.00:1 and an interest coverage ratio of greater than 3.00:1. The two facilities have substantially similar terms and conditions and continue to be secured by all Hudbay assets except for those assets related to the Arizona business unit.

SUMMARY

Third Quarter Operating and Financial Results

Generated $359.0 million in revenue, $103.5 million of operating cash flow before change in non-cash working capital and $119.3 million of adjusted EBITDA^1^ in the third quarter of 2021 from higher realized base metals prices and higher gold sales volumes, partially offset by lower base metals sales volumes.
Consolidated copper production in the third quarter was 23,245 tonnes; quarterly consolidated gold production increased by 35% to 53,872 ounces in the third quarter, compared to the second quarter in 2021, a record for Hudbay.
Consolidated cash cost and sustaining cash cost per pound of copper produced, net of by-product credits^1^, were $0.62 and $1.97, respectively, an improvement of 26% and 12% compared to the second quarter of 2021.
Third quarter Peru production was boosted by significantly higher gold grades from Pampacancha and record gold recoveries, leading to record quarterly gold revenue. Pampacancha production continues to ramp-up, achieving a 109% increase in ore production quarter over quarter.
Third quarter Manitoba production benefited from higher throughput and higher gold grades at Lalor but was negatively impacted by lower zinc grades and zinc recoveries, limiting overall zinc concentrate feed to the zinc plant. Manitoba results included initial gold production from New Britannia's gold circuit.
On track to meet annual production guidance for copper, gold, zinc and silver in concentrate and doré, consolidated sustaining capital expenditures, and Manitoba unit operating cost in 2021. After adjusting for unbudgeted COVID-related costs in Peru, full year unit operating costs for Peru are expected to be around the top end of the 2021 guidance range.
Third quarter net loss and loss per share were $170.4 million and $0.65, respectively. After normalizing for an impairment charge related to higher estimated closure costs associated with our updated Flin Flon closure plan and Flin Flon restructuring charges, amongst other items, third quarter adjusted net earnings^1^ per share were $0.15.
Cash and cash equivalents increased during the third quarter to $297.5 million as at September 30, 2021, mainly as a result of $139.8 million of cash generated from operations, partially offset by $89.1 million of capital investments primarily for the construction of the New Britannia project and sustaining capital expenditures, and $33.6 million of interest paid on our senior unsecured notes.

Executing on Growth Initiatives

New Britannia has achieved project completion as construction activities at the new copper flotation facility concluded in October. Refurbishment and commissioning activities at the gold mill were completed in July 2021, and the mill achieved first gold production on August 11, 2021. Commissioning of the copper circuit was completed and first production of concentrate was achieved in October, ahead of the original schedule, while ramp-up activities at the flotation plant continue. Annual gold production from Lalor and the Snow Lake operations is on track to increase to over 180,000 ounces at an average cash cost and sustaining cash cost, net of by-product credits, of $412 and $788 per ounce of gold, respectively, during the first six full years of operation starting in 2022.
Mining activities at the Pampacancha satellite pit continue to advance as planned with grades and tonnes reconciling well against the mine plan, achieving the expected increase in gold grades in 2021 and on track for achieving higher copper grades in 2022, in line with recent Company guidance.
Recent Copper World drilling has identified three new deposits for a total of seven distinct deposits with a combined strike length of over seven kilometres. The Company remains on track to complete an initial inferred resource estimate before the end of the year and a preliminary economic assessment in the first half of 2022.
Scoping study planned for 2022 to examine the opportunity to reprocess tailings in Flin Flon after the closure of the 777 mine, which could further increase metal production, defer closure costs and reduce the environmental footprint of the tailings facility.
Amended and restated our senior secured revolving credit facilities to increase available borrowings to $450 million and enhance our financial flexibility, while extending the maturity to 2025.

Summary of Third Quarter Results

Cash generated from operating activities in the third quarter of 2021 increased to $139.8 million compared to $77.9 million in the same quarter of 2020. Operating cash flow before change in non-cash working capital was $103.5 million during the third quarter of 2021, reflecting an increase of $19.1 million compared to the same period of 2020. The increase in operating cash flow is primarily the result of higher realized base metal prices and higher gold sales volumes, partially offset by lower base metals sales volumes.

Consolidated copper production in the third quarter of 2021 decreased by 8% compared to the same period in 2020 primarily as a result of lower throughput and copper grades in Peru, partially offset by higher throughput, grades and recoveries in Manitoba. Consolidated gold production in the third quarter of 2021 increased by 84% compared to the third quarter of 2020, due to significantly higher gold grades from Pampacancha and record gold recoveries in Peru, along with significantly higher gold grades at Lalor. Consolidated zinc production in the quarter decreased by 32%, versus the comparative quarter in 2020, primarily as a result of changes in grades and recoveries. Consolidated silver production in the third quarter increased by 14% compared to the same period in 2020, as a result of higher grades in Peru. Hudbay achieved record molybdenum recoveries in the third quarter which contributed to record quarterly molybdenum revenues.

Net loss and loss per share in the third quarter of 2021 were $170.4 million and $0.65, respectively, compared to a net loss and loss per share of $24.0 million and $0.09, respectively, in the third quarter of 2020. Third quarter results were negatively impacted by an updated closure plan reflecting higher estimates for closure activities in Flin Flon, primarily related to water treatment costs. The higher closure cost estimate has resulted in an increase to our environmental obligation and a corresponding increase to Flin Flon's property plant and equipment ("PP&E"). However, as the closure of Flin Flon is expected to commence within 12 months, an impairment charge was made to PP&E resulting in a loss of $147.3 million. The quarterly financial results were also negatively impacted by Flin Flon restructuring charges comprising an inventory supplies write down of $5.4 million and a severance accrual of $3.6 million for unionized employees, as well as an increase in past service pension cost provision of $4.2 million related to pensions for Manitoba unionized employees.

Adjusted net earnings^1^and adjusted net earnings per share^1^ in the third quarter of 2021 were $38.2 million and $0.15 per share after normalizing for an impairment charge related to the updated Flin Flon closure plan and the Flin Flon restructuring charges, among other items. This compares to an adjusted net loss and adjusted net loss per share of $25.4 million, and $0.10 per share in the same period of 2020. Third quarter adjusted EBITDA^1^was $119.3 million, compared to $96.1 million in the same period of 2020.

As at September 30, 2021, our liquidity includes $297.5 million in cash and cash equivalents as well as undrawn availability of $297.3 million under our revolving credit facilities. The Company's liquidity position was further enhanced in October through the successful renegotiation of the credit facilities to increase available borrowings to $450 million, while extending the maturity to 2025.

^2^ In millions.

In the third quarter of 2021, consolidated cash cost per pound of copper produced, net of by-product credits^1^, was $0.62, compared to $0.65 in the same period in 2020. This decrease was a result of higher gold and molybdenum byproduct credits partially offset by higher operating costs in Peru and Manitoba and lower copper production.

Sustaining cash cost per pound of copper produced, net of by-product credits^1^, decreased to $1.97 in the third quarter of 2021, from $2.02 in the same period in 2020, primarily due to the same reasons affecting cash cost as well as lower sustaining capital expenditures. All-in sustaining cash cost per pound of copper produced, net of by-product credits^1^, in the third quarter of 2021 was $2.18, which decreased from $2.25 in the same period last year primarily due to the same reasons.

We expect our consolidated cash cost and sustaining cash cost per pound of copper produced, net of by-product credits, to be within the guidance ranges for 2021.

RECENT DEVELOPMENTS

COVID-19 Business Update

On a population adjusted basis, we continue to see a steady decline in the number of new cases of COVID-19 in the regions in which we operate. Despite these encouraging declines, we are maintaining stringent COVID-19 measures and controls to ensure the safety of our workforce, partners and communities. As such, we continue to experience an ongoing financial and, to a lesser extent, operating impact from COVID-19.

New Britannia First Gold Production Achieved and Copper Flotation Facility Fully Commissioned

On August 11, 2021, gold production commenced at the New Britannia mill after refurbishment, commissioning and start-up activities were completed earlier in the summer. First gold production was achieved in line with the timelines assumed in recent guidance and ahead of the original schedule to produce first gold before the end of 2021. Annual gold production from Lalor and the Snow Lake operations is expected to increase to over 180,000 ounces at an average cash cost and sustaining cash cost, net of by-product credits, of $412 and $788 per ounce of gold, respectively, during the first six full years of New Britannia's operation.

The construction of a new copper flotation facility was completed in October 2021, followed by a brief commissioning period completed ahead of the project timeline expectations. The copper facility consists of an innovative and first-of-its-kind flotation circuit based entirely on Jameson cells, a modern pneumatic flotation design that offers a compact layout, low-cost process and flexible flowsheet. First production of copper concentrate was achieved in October and ramp-up of the copper circuit is now underway. New Britannia is expected to achieve its targeted design capacity and commercial production in the fourth quarter of 2021.

Advancing the Copper World Discovery

On September 22, 2021, the results from drilling completed at Copper World between January and June 2021 were released. The drill program totaled over 91,000 feet and intersected additional high-grade copper sulphide and oxide mineralization on our wholly-owned private land in Arizona. The Copper World project is located within seven kilometres of our Rosemont copper project and has mineralization located closer to surface than Rosemont, indicating the possibility of lower strip ratios at Copper World. We recently increased our private land package to approximately 2,400 acres in the west, which together with patented mining claims, now totals approximately 4,500 acres to support an operation entirely on private land.

The 2021 drilling identified three new deposits, for a total of seven deposits at Copper World, covering a combined seven kilometres with mineralized occurrences. The three new deposits are called Bolsa, South Limb and North Limb. The program also confirmed and increased the confidence in the size and quality of the existing Copper World, Broad Top Butte, Peach and Elgin deposits.

There remains the potential for continuity between the Bolsa discovery and the Rosemont deposit as highlighted by three new holes drilled on the western edge of Rosemont, which intersected high-grade copper mineralization similar to the mineralization intersected at Bolsa. For example, drill hole #177 intersected 833 feet of 0.40% copper, including 121 feet at 1.32% copper (please refer to the news release dated September 22, 2021 for additional drill hole information). There remains a 1,500-foot gap in drilling coverage between these three holes and the Bolsa discovery, and we are developing plans to test this unexplored area.

Given the continued positive results from the exploration program at Copper World, the 2021 drill program was previously expanded from an original 70,000 feet of drilling to over 200,000 feet to be completed by the end of the year with four drill rigs continuing to operate at site. We are testing the opportunity to use reverse circulation drilling to fast-track future infill drilling programs. This drilling is intended to delineate and upgrade the resource for the seven deposits, while focusing on bridging the gap between the Bolsa discovery and the area west of the Rosemont deposit. The drill program will also continue to explore prospective areas outside of the known deposits.

We expect to complete an initial inferred mineral resource estimate for the seven deposits at Copper World before the end of 2021. These mineral resource estimates will form the basis for a preliminary economic assessment ("PEA") expected to be released in the first half of 2022. Mineralogical studies and metallurgical testing programs are underway, and the preliminary results are expected to be incorporated into the PEA. Hudbay continues to progress geotechnical and hydrogeological studies over the Copper World area.

In October, we received approval from the Arizona State Mine Inspector for our Mined Land Reclamation Plan ("MLRP") for Copper World. The MLRP approval includes the requirement for reclamation cost bonding prior to initiating work on our private lands and represents the first step in the state-level permitting process for a private land operation.

The budget for Copper World in 2021 is expected to total approximately $34 million, which increased from the original $10 million budget, to fund the larger drill program and complete the various technical studies. We will also continue to examine future potential synergies with an operation at Rosemont.

Other Exploration Updates

Peru Regional Exploration

Ongoing evaluation of the underground potential at Constancia Norte supports plans for additional drilling activities in the fourth quarter of 2021. The drilling is expected to confirm continuity and test extensions, which together with the results from an underground scoping study, are expected to be incorporated into the annual mineral reserve and resource update for Constancia in March 2022.

Hudbay continues to progress discussions with the community of Uchucarcco on the Maria Reyna and Caballito properties, both of which are located within ten kilometres of Constancia.

Drilling continues at the Llaguen copper porphyry target located in northern Peru, near the city of Trujillo and in close proximity to existing infrastructure. The initial confirmatory phase of the drill program is expected to total 6,000 metres in 14 holes with two drill rigs presently turning at site. Five holes totaling 2,795 metres have been completed with all holes intersecting mineralization. Pending positive results from this initial drilling phase, a second phase aimed at defining an initial inferred mineral resource for Llaguen would follow in the second quarter of 2022 after the rainy season.

Snow Lake Regional Exploration

The Company's regional exploration efforts in the Snow Lake area continue, following on the success from the 2021 winter drill program in the Chisel Basin where the copper-gold rich feeder of the 1901 deposit was discovered and high-grade zinc and gold mineralization was confirmed through infill and extension drilling. We are planning a 2022 drill program for 1901 to test the down-plunge extensions of the copper-gold rich feeder zone.

Hudbay's 2021 summer program included regional surface mapping and ground geophysical surveys to delineate the higher priority drill targets for 2022. One of the more promising targets was identified from a borehole survey immediately north of Lalor and is expected to be drill tested in early 2022 both from surface and from underground.

Ongoing infill drilling continues at Lalor and the results are expected to be incorporated into the annual mineral reserve and resource estimates to be published at the end of March 2022.

Flin Flon Reclamation Obligations and Tailings Reprocessing Opportunity

As part of the Company's ongoing efforts to update our Flin Flon closure plan, a comprehensive update completed in the third quarter of 2021 resulted in an increase to the decommissioning and restoration ("DRO") provision of approximately $144 million compared to June 30. This increase is mostly attributable to long-term water treatment and monitoring obligations, along with cost inflation for other remediation activities. The increase in water management costs is primarily a result of the addition of 22 years to the post-closure water management period (to the year 2122), which after applying a very low discount rate, represents a significant portion of the DRO increase. As of September 30, 2021, on an undiscounted basis, the total estimated environmental obligations related to our Flin Flon operations were $322 million, of which approximately 25% is expected to occur over the next 15 years in connection with the closure of the Flin Flon operations, while approximately 75% of the obligations are scheduled to be incurred after the closure of the Snow Lake operations, which is currently expected in 2037 based on reserves. The full breakdown is as follows:

• $23 million for previously announced tailings stability activities that will be completed in 2021 and 2022;

• $13 million for demolition costs between the cessation of operations in Flin Flon and 2030;

• $33 million for the construction and operation of a water treatment plant between 2030 and 2042;

• $46 million for demolition and tailings remediation costs after Snow Lake mining activities conclude in 2037 (based on current reserves) until 2042;

• $161 million in post-closure environmental management activities (such as water collection and treatment) from 2037 to 2122; and

• $46 million in other site management costs and remediation activities.

As part of the engineering work done to update the closure plan, we have identified the opportunity to reprocess tailings at our Flin Flon Tailings Impoundment System ("FFTIS") where tailings from processing activities in Flin Flon have been deposited for over 90 years. We are in the early stages of technical evaluation and confirmatory drilling to support the completion of a scoping study in 2022. Pending positive results from the scoping study, further feasibility studies would follow. This opportunity could utilize the Flin Flon concentrator, with modifications, after closure of the 777 mine, creating operating and economic benefits to the Flin Flon community. It could also provide the opportunity to redesign the closure plans, increase metal production, defer certain closure costs and reduce the environmental footprint of the FFTIS.

Collective Bargaining Agreements Ratified in Manitoba

New three-and-a-half year collective agreements were ratified by the members of USW Local 7106 and USW Local 9338 in September 2021. Members of the other four unions at Hudbay's Manitoba operations ratified their respective three-and-a-half year collective agreements in July. This completed the collective bargaining process with all six of the Company's unions in Manitoba.

Credit Facility Extension and Amendments

On October 26, 2021, we amended and restated our senior secured revolving credit facilities (the "Credit Facilities") to increase the total amount of available borrowings to $450 million, eliminate certain financial covenants while amending others to increase our financial flexibility, reduce the effective interest rate and extend the maturity to October 26, 2025. The remaining financial covenants include maintaining a net debt to EBITDA ratio of less than 4.00:1, a senior secured debt to EBITDA of less than 3.00:1 and an interest coverage ratio of greater than 3.00:1.

While Peru has experienced notable improvements in COVID-19 statistics throughout 2021, Hudbay continues to maintain stringent COVID-19 measures and controls to ensure the safety of our workforce, partners and the communities in which we operate. This has allowed Constancia to continue to operate safely although it has resulted in elevated unit operating costs due to the ongoing COVID-related protocols.

Total ore mined during the third quarter of 2021 decreased 2% from the comparative 2020 period. Ramp-up of mining activity at Pampacancha has increased steadily since first production in April 2021. Total Pampacancha ore mined during the third quarter of 2021 increased by 109% to 2.1 million tonnes compared to the second quarter of 2021.

Ore milled during the third quarter of 2021 was 7% lower than the same period in 2020 due to increased ore hardness and a planned semi-annual mill maintenance shutdown in July. Compared to the same period in 2020, milled copper grades in the third quarter have declined by 9% while gold and silver grades increased by 267% and 47%, respectively, due to significantly higher gold and silver head grades from Pampacancha.

Peru achieved record recoveries of gold in the third quarter of 2021, significantly above the comparative 2020 period, mainly due to higher grades. Meanwhile, copper recoveries increased due to lower levels of contaminants and silver recoveries decreased as a result of lower-than-expected recoverable silver values in the earlier, more oxidized ores from Pampacancha. Recent metallurgical test work indicates that Pampacancha silver recoveries are expected to increase to targeted levels in 2022.

Year-to-date ore milled in 2021 was 12% higher than the comparative period in 2020 due to an eight-week suspension of operations in 2020 at the onset of the COVID-19 pandemic. Year-to-date recoveries of copper, gold and molybdenum in 2021 were higher and silver was lower than the same period in 2020 due to the same factors as described above for the quarter-over-quarter variance.

Combined mine, mill and G&A unit operating costs in the third quarter of 2021 were 18% higher than the same period in 2020 primarily due to higher overall costs and fewer tonnes milled. Costs were higher in 2021 as a result of higher ore hardness, higher steel prices affecting grinding media costs and COVID-19 expenditures. Year-to-date unit operating costs were 28% higher due to the same factors as described above for the quarter-over-quarter variance and due to more material moved.

COVID-related costs in Peru were $4.8 million in the third quarter of 2021 and are expected to continue at a similar run-rate into the fourth quarter of 2021. Unit operating costs in the third quarter were $10.93 per tonne excluding these COVID-related costs. We expect Peru unit operating costs to be around the top end of the 2021 guidance range after adjusting for unbudgeted COVID-related costs.

Production of gold and silver was higher in the third quarter of 2021 and year-to-date compared to the same periods in 2020 due to significantly higher gold and silver head grades from Pampacancha, higher gold recoveries and an eight-week suspension of operations in 2020 at the onset of the COVID-19 pandemic. Production of copper was lower in the third quarter of 2021 due to a decline in copper grades compared to the same period in 2020.

Other than molybdenum, which we expect will fall slightly below the 2021 guidance range but in line with the recently published mine plan, we expect the production of all remaining metals in Peru to be in line with 2021 full year guidance.

Cash cost per pound of copper produced, net of by-product credits, for the three and nine months ended September 30, 2021 were $1.26 and 1.65, respectively. The cash costs in the third quarter of 2021 decreased 18% compared to the same period in 2020 due to higher by-product credits from gold and molybdenum, partially offset by lower copper production and higher overall mining, milling, general and administrative costs.

Year-to-date cash costs increased 14% compared to the same period in 2020 due to comparatively higher mining, milling, general and administrative costs in 2021 as a result of lower grades, ore hardness and higher COVID costs incurred, as well as an eight-week COVID-related suspension of operations in 2020, partially offset by higher by-product credits and higher copper production.

Sustaining cash cost per pound of copper produced, net of by-product credits for the three and nine months ended September 30, 2021 increased by 1% and 20%, respectively, compared to the same periods of 2020, mainly due to the same factors affecting cash costs noted above and higher sustaining capital expenditures on a comparative basis due to fewer expenditures incurred during the eight-week COVID-related suspension of operations in 2020.

Ore mined at our Manitoba operations during the third quarter of 2021 was 4% higher than the same period in 2020. Gold and copper grades mined during the three months ended September 30, 2021 were 43% and 18% higher, respectively, compared to the same period in 2020, mainly due to increased mining of gold and copper-gold stopes at Lalor, in line with the mine plan. Zinc grades mined during the three months ended September 30, 2021 were 27% lower than the same period in 2020 as mining of the gold zones at Lalor were prioritized during the quarter.

Mining operations at Lalor have started to consistently produce and separate the gold and copper-gold ores as feed for the New Britannia mill. At the end of the third quarter of 2021, approximately 35,000 tonnes of gold ore is stockpiled as feed for New Britannia, a decrease of approximately 12,000 tonnes from the end of the second quarter of 2021. The 777 mine is now within nine months of closure and the focus continues to be on mining out the remaining reserves by completing the necessary ground rehabilitation in order to access old workings and remnant stopes.

Total unit operating costs for the mines during the third quarter of 2021 increased by 17% compared to the same period in 2020 mainly due to lower capitalized development at 777 as all costs are now operating in nature and higher contractor, camp and COVID-19 related expenses at Lalor. Year-to-date total unit operating costs in Manitoba were 18% higher as compared to the same period in 2020 due to the same factors as the third quarter variances as well as lower capitalized development at both Lalor and 777.

During the third quarter of 2021, New Britannia processed 41,827 tonnes of high gold content ore and produced 404 ounces of gold in doré after, pouring its first gold doré bar on August 11. The gold and silver recoveries are expected to increase in the fourth quarter after ramp-up of the mill during the third quarter. Construction of the new copper flotation circuit was completed in October 2021, followed by a brief commissioning period completed ahead of schedule. Ramp-up activities at the copper circuit are underway and are on track for commercial production in the fourth quarter of 2021.

Ore processed at the Stall concentrator and New Britannia mill during the third quarter of 2021 was 22% higher than the same period in 2020. Combined Stall and New Britannia recoveries during the third quarter of 2021 were higher for copper and lower for zinc and precious metals versus the comparative period in 2020 but were consistent with expectations as the third quarter was a partial ramp-up period for the New Britannia mill. Unit operating costs at Stall and New Britannia increased by 8% during the third quarter compared to the same period in 2020 primarily due to the incorporation of operating costs from New Britannia.

Operations at the Flin Flon concentrator during the third quarter of 2021 were constrained by ore feed availability from 777 and, as such, ore processed was 20% lower compared to the same period in 2020 which included some processing of ore stockpiles. Recoveries of copper, gold and silver at the Flin Flon concentrator during the third quarter of 2021 were higher by 2%, 5% and 1%, respectively, compared to the same period in 2020 mainly due to higher copper head grades from the 777 mine, consistent with the metallurgical model. Unit operating costs at the Flin Flon concentrator increased by 22% during the third quarter compared to the same period in 2020 primarily due to lower production and higher tailings operating costs as we approach Flin Flon closure and plan for the transition of the facility to care and maintenance in mid-2022.

Year-to-date ore processed at Snow Lake in 2021 increased by 5% versus the comparative period in 2020 due to the commencement of operations at the New Britannia mill in August. Year-to-date ore processed at the Flin Flon mill was 11% lower than the comparative 2020 period as excess ore mined at Lalor stopped being milled in Flin Flon in May 2021.

Combined mine, mill and G&A unit operating costs in the third quarter of 2021 increased by 17% compared to the same period in 2020, due to higher overall operating costs for the reasons described above. Year-to-date combined mine, mill and G&A unit operating costs were 15% higher than the prior year due to the same factors as the third quarter variances.

Compared to the same period in 2020, copper and gold production in the third quarter of 2021 increased by 13% and 40%, respectively, while silver was relatively unchanged. These increases were primarily due to higher grades and higher overall throughput. Zinc production decreased 32% in the quarter with Lalor mining transitioning to the gold lenses and 777 contributing lower throughput and zinc grades.

Year-to-date production of copper, silver and zinc declined by 1%, 14% and 24%, respectively, compared to the same period in 2020 primarily due to COVID-19 and other production interruptions experienced in the second quarter of 2021 and lower mine grades for silver and zinc. Gold production increased by 16% during the same time frame versus the comparative period mainly due to higher gold grades at both mines offset by lower throughput and recoveries.

Full year production of all metals in concentrate and unit operating costs in Manitoba are on track to achieve the guidance ranges for 2021.

Production of refined cast zinc in the third quarter of 2021 was 26% lower than the same period in 2020 due to lower zinc grades and lower zinc recoveries resulting in lower zinc concentrate availability from the mills. Operating costs per pound of zinc metal produced was higher by 15% over the same period primarily due to lower production. Year-to-date refined zinc metal production decreased by 17% compared to the same period of 2020 due to the same factors.

Due to the factors impacting zinc concentrate production noted above, and with the Lalor mine transitioning from zinc lenses to gold lenses as New Britannia ramps up, Hudbay expects full year production of cast zinc to fall below our 2021 guidance. As a result, zinc plant unit operating costs are expected to finish the year at the top end of the 2021 guidance range.

Cash cost per pound of copper produced, net of by-product credits, in the third quarter of 2021 was negative $1.64. These costs were higher compared to the same period in 2020, as a result of higher mining and milling costs and lower by-product revenues offset by higher copper production. Cash cost per pound of copper produced, net of by-product credits, for the first nine months of 2021 were lower compared to the same period in 2020, primarily due to higher by-product credits partially offset by higher mining and milling costs.

Sustaining cash cost per pound of copper produced, net of by-product credits, in the third quarter of 2021 was $0.75. These costs were lower compared to the same period in 2020, primarily due to the reasons listed above and lower comparative sustaining capital expenditures. Sustaining cash cost per pound of copper produced, net of by-product credits, for the first nine months of 2021 were lower compared to the same period in 2020 for the same reasons as indicated above.

Cash cost and sustaining cash cost per pound of zinc produced, net of by-product credits, in the third quarter of 2021 and year-to-date were generally in line with the same periods in the prior year despite zinc production being considerably lower in 2021. This resulted from significantly higher by-product credits and lower sustaining capital expenditures, offset by higher mining and milling costs.

FINANCIAL REVIEW

Financial Results

In the third quarter of 2021, we recorded a net loss of $170.4 million compared to a net loss of $24.0 million for the same period in 2020, representing a decrease in profit of $146.4 million. Year-to-date in 2021, we recorded a net loss of $233.9 million compared to a net loss of $152.0 million for the same period in 2020, representing a decrease in profit of $81.9 million.

Revenue

Revenue for the third quarter of 2021 was $359.0 million, $42.9 million higher than the same period in 2020, mainly due to higher realized base metal prices as well as higher sales volumes of gold. Offsetting this increase were lower precious metal prices and lower base metal volumes due to lower Manitoba zinc grades and lower Constancia copper grades.

Revenue for the first nine months of 2021 was $1,076.8 million, $306.7 million higher than the same period in 2020, mainly due to higher realized base metal prices as well as higher sales volumes of copper and gold and strong revenues from molybdenum as a result of higher realized prices. Offsetting these increases were lower realized gold prices and lower sales volumes of zinc due to lower Manitoba throughput and recoveries from lower Manitoba zinc grades. The significantly increased sales volumes of gold is largely the result of the commencement and subsequent ramp-up of the high-grade Pampacancha deposit starting in the second quarter of 2021 as well as comparatively lower production in the prior year period due to the temporary suspension of Constancia operations following a government declared state of emergency.

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 three and nine months ended September 30, 2021 and 2020, respectively, are summarized below:

All values are in US Dollars.

^1^Realized prices exclude refining and treatment charges and are on the sale of finished metal or metal in concentrate. Realized prices include the effect of provisional pricing adjustments on prior period sales.

^2^ London Metal Exchange average for copper and zinc prices.

^3^ All sales for the three and nine months ended September 30, 2021 and 2020 were cast zinc metal. Zinc realized prices include premiums paid by customers for delivery of refined zinc metal, but exclude unrealized gains and losses related to non-hedge derivative contracts that are included in zinc revenues.

^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.

Total cost of sales for the third quarter of 2021 was $297.1 million, reflecting an increase of $20.2 million from the third quarter of 2020. Peru cost of sales decreased by $7.4 million in the third quarter of 2021, compared to the same period of 2020. This decrease is mainly related to lower depreciation and lower relative changes in product inventory caused by an increase in ore stockpiles, partially offset by higher overall mining, milling, general and administrative costs. Manitoba cost of sales increased by $27.6 million in the third quarter of 2021, compared to the same period of 2020, mainly due to higher overall mining and milling costs, a drawdown of finished goods inventory and a $9.6 million charge related to past service pension costs and inventory adjustments for certain materials and supplies inventories in Flin Flon. This increase was partially offset by lower depreciation.

Total cost of sales year-to-date in 2021 was $880.2 million, reflecting an increase of $114.8 million from the same period in 2020. In Peru, costs increased in the first nine months of 2021 by $54.2 million, largely due to higher overall mining, milling, general and administrative costs, higher depreciation and freight costs, partially offset by a lower relative changes in product inventory caused by an increase in ore stockpiles and a $31.9 million fixed overhead charge (cash: $15.8 million, non-cash: $16.1 million included in depreciation) being recorded in the comparative 2020 period with no corresponding charges recorded in 2021. In Manitoba, cost of sales increased by $60.6 million compared to the first nine months of 2020 largely due to the same factors as the third quarter variance as well as higher administrative costs, including COVID-related costs and higher freight costs.

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

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

- Exploration and evaluation expenses increased by $4.2 million, as the Copper World drilling program and related metallurgical studies continued during the third quarter of 2021.

- Other net operating expenses increased by $11.2 million, mostly related to the loss on disposal of $5.2 million of plant and equipment at New Britannia, $3.9 million in higher drilling and project engineering costs related to Copper World and a $3.6 million restructuring charge in Manitoba for severance related to the closure of the Flin Flon operations.

For year-to-date 2021, other significant variances in expenses from operations, compared to the same period in 2020, include the following:

- Exploration and evaluation expenses increased by $15.8 million compared to 2020 for the same reason as noted above.

- Other operating expenses increased by $2.1 million, for the same reasons as above offset by a relative gain on the revaluation of the DRO liability on non-producing properties in Manitoba.

^1^Includes interest income and other finance expense.

^2^Includes variable consideration adjustment (prior periods).

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

During the quarter ended September 30, 2021, net finance expense decreased by $14.6 million compared to the same period in 2020 due to a $9.5 million decrease in accrued finance costs and a $5.1 million decrease in non-cash finance costs.

These decreases were primarily driven by a $2.4 million reduction in interest expense on long-term debt as a result of refinancing of our senior notes at lower interest rates during the third quarter of 2020 and first quarter of 2021, a reduction of $7.3 million in early redemption premiums paid in 2020, a $3.8 million write-down of unamortized transaction costs in 2020, a $2.5 million reduction of the accretion on streaming agreements arising from a lower interest rate on the amended Peru streaming agreement, an $8.9 million decrease in non-cash losses on the revaluation of the gold prepayment liability and lower non-cash foreign exchange revaluation gains of $1.9 million. Offsetting these reductions in net finance expense were lower revaluation gains of $2.6 million on our investments consisting of securities in Canadian metals and mining companies and a $9.1 million reduction in revaluation gains on an embedded derivative associated with our senior notes.

During the nine months ended September 30, 2021, net finance expense increased by $46.7 million compared to the same period in 2020 due to a $33.9 million increase in non-cash finance costs as well as a $12.8 million increase in accrued finance costs.

These increases were primarily related to the refinancing of our 2025 senior notes in the first quarter of 2021. The early redemption of these notes resulted in a $49.8 million write off of the non-cash embedded derivative related to the exercise of the prepayment option. Also, in connection with the refinancing, we expensed an additional $15.6 million in call premiums, compared to the same period in 2020. We also incurred an increase of $7.8 million in revaluation losses on our investments consisting of securities in Canadian metals and mining companies. Offsetting these increases in net finance expense was a $23.0 million increase in non-cash gains on the revaluation of the gold prepayment liability and an $8.5 million decrease in accretion on streaming arrangements for the same reasons as described above.

Tax Expense

For the three and nine months ended September 30, 2021, tax expense increased by $22.6 million and $59.3 million respectively, compared to the same period in 2020. The following table provides further details:

^1^Deferred tax expense (recovery) represents our draw down/increase of non-cash deferred income and mining tax assets/liabilities.

Income Tax Expense

Applying the estimated Canadian statutory income tax rate of 26.4% to our loss before taxes of $202.6 million for the year-to-date period in 2021 would have resulted in a tax recovery of approximately $53.5 million; however, we recorded an income tax expense of $5.2 million. The significant items causing our effective income tax rate to be different than the 26.4% 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 $5.9 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 $48.0 million.

^-^ Certain foreign exchange gains and other items are not taxable for local income tax purposes and therefore result in a deferred tax expense of $1.6 million.

^-^ Certain deductible temporary differences with respect to our foreign operations are recorded using an income tax rate other than the Canadian statutory income tax rate of 26.4%, resulting in a deferred tax expense of $14.3 million.

Mining Tax Expense

Applying the estimated Manitoba mining tax rate of 10.0% to our loss before taxes of $202.6 million for the year-to-date period in 2021 would have resulted in a tax recovery of approximately $20.3 million; however, we recorded a mining tax expense of $26.1 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 September 30, 2021, at the tax rate we expect to apply when temporary differences reverse.

LIQUIDITY AND CAPITAL RESOURCES

Senior Unsecured Notes

Following our recent bond refinancings, we now have $600.0 million aggregate principal amount of 4.5% senior notes due April 2026 and $600.0 million aggregate principal amount of 6.125% senior notes due April 2029.

Extension and Amendment of Senior Secured Revolving Credit Facilities

On October 26, 2021, we entered into amendments to our Credit Facilities to increase the total amount of the facilities to $450 million ($150 million for the Peru facility and $300 million for the Canadian facility), eliminate certain financial covenants, and amend others to increase our financial flexibility and reduce interest spreads across the entire net debt to earnings before interest, tax, depreciation and amortization ("EBITDA") grid. In addition, the maturity date of the facilities was extended to October 26, 2025. The remaining financial covenants have been amended and include maintaining a net debt to EBITDA ratio of less than 4.00:1, a senior secured debt to EBITDA of less than 3.00:1 and an interest coverage ratio of greater than 3.00:1. The two facilities have substantially similar terms and conditions and continue to be secured by all our assets except for those assets related to the Arizona business unit.

As at September 30, 2021, our liquidity includes $297.5 million in cash and cash equivalents as well as undrawn availability of $297.3 million under our Credit Facilities (which excludes the $50 million increase in availability resulting from the recent amendment to our Credit Facilities). As at September 30, 2021, we were in compliance with our covenants under the Credit Facilities and had drawn $102.7 million in letters of credit under the Credit Facilities. Due to the updated Flin Flon closure plan finalized in the third quarter of 2021, we expect the letters of credit issued under the Credit Facilities to increase in the near future to support the higher estimated closure costs.

As at September 30, 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 $87.1 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 September 30, 2021 compared to December 31, 2020

Cash and cash equivalents decreased by $141.7 million during the first nine months of the year to $297.5 million as at September 30, 2021. This decrease was mainly the result of $272.6 million of capital investments primarily at our Peru and Manitoba operations, interest payments of $84.4 million, other financing and leasing payments of $41.2 million and $28.4 million, respectively, as well as paid dividends of $4.1 million. Offsetting these cash outflows was cash flow from operating activities of $288.0 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 $147.0 million to $159.9 million from December 31, 2020 to September 30, 2021, primarily due to the cash and cash equivalent decrease of $141.7 million, an increase of $50.7 million in other financial liabilities due to a partial reclassification of the gold prepayment liability to current and a decrease in trade and other receivables of $15.6 million, mainly related to timing of sales receivables. Offsetting these items was a decrease in trade and other payables of $55.9 million arising mainly from timing of interest payments on our senior notes, a decrease of $24.9 million in our current portion of deferred revenue related to our stream agreements and an increase in other financial assets of $16.3 million related to the revaluation of our copper and zinc derivatives.

Cash Flows

The following table summarizes our cash flows for the three and nine months ended September 30, 2021 and September 30, 2020:

(in $ thousands)	Three months ended				Nine months ended
	Sep. 30,2021	Sep. 30, <br>2020			Sep. 30, 2021		Sep. 30, <br>2020

Increase (decrease) in cash and cash equivalents	3,164	57,878			(141,684	)	52,868

Cash Flow from Operating Activities

Cash generated from operating activities was $139.8 million during the third quarter of 2021, an increase of $61.9 million compared with the same period in 2020. Operating cash flow before change in non-cash working capital was $103.5 million during the third quarter of 2021, reflecting an increase of $19.1 million compared to the third quarter of 2020. The increase in operating cash flow is primarily the result of higher realized base metal prices, and higher gold sales volumes. This was partially offset by lower sales volumes of base metals compared to the third quarter of 2020.

Year-to-date cash generated from operating activities was $288.0 million, representing an increase of $169.6 million compared to the same period in 2020. Operating cash flow before change in non-cash working capital was $326.9 million during the first nine months of 2021, compared to $155.8 million in the same period in 2020. The year-to-date increase in operating cash flow is due to the same factors described above for the quarter-over-quarter variance as well as the Constancia shut-down that occurred in the comparative 2020 period.

Cash Flow from Investing and Financing Activities

During the third quarter of 2021, we spent $136.7 million in investing and financing activities, primarily driven by $89.1 million in capital expenditures, $33.6 million in interest payments, $9.6 million in capitalized lease payments and $4.6 million in other financing and dividend payments.

Year-to-date, we spent $428.0 million in investing and financing activities, driven by $272.6 million in capital expenditures, $84.4 million in interest payments, $41.2 million in other financing payments, $28.4 million in capitalized lease payments and $4.1 million in dividends paid.

Capital Expenditures

The following summarizes accrued and cash additions to capital assets for the periods indicated:

All values are in US Dollars.

^1^Peru sustaining capital expenditures includes capitalized stripping costs.

^2^ Hudbay's revised growth capital guidance for Peru of $25.0 million includes the cost of individual land user agreements.

^3^Hudbay's revised growth capital guidance for Manitoba of $105.0 million was revised in August 2021.

^4^Other capitalized costs include decommissioning and restoration adjustments.

Sustaining capital expenditures in Manitoba for the three and nine months ended September 30, 2021 were $23.5 million and $77.9 million, respectively, representing increases of $0.2 million and $3.6 million compared to the same periods in 2020. The increases are due to increased expenditures at the Anderson tailings facility in 2021, partially offset by a suspension of capital additions at 777, effective July 2021.

Sustaining capital expenditures in Peru for the three and nine months ended September 30, 2021 were $38.9 million and $83.9 million, respectively, representing increases of $3.9 million and $29.7 million compared to the same period in 2020. The increases were mainly due to curtailed spending in the comparative 2020 periods arising from an eight-week suspension of Constancia operations. During the third quarter of 2021, sustaining capital expenditures mainly related to a tailings management facility expansion, construction of a tailings discharge line and higher capitalized stripping from mining operations at Pampacancha.

Manitoba's year-to-date growth capital of $97.2 million relates primarily to capital spending to complete the New Britannia refurbishment project. The project was completed in October, following the completion of construction and full commissioning of the new copper flotation facility. Ramp-up activities at the copper circuit are currently underway.

Peru's year-to-date growth capital of $23.1 million, incurred mainly in the first quarter, includes costs associated with the remaining land user agreements as well as civil works related to the development of Pampacancha before reaching commercial production in April. Subsequent capital spending in the third quarter is related to the Pampacancha land access agreements.

We expect consolidated sustaining capital expenditures in 2021 to be in line with our full year guidance and we expect our growth capital expenditures in 2021 to be in line with our revised full year guidance.

Other capitalized costs for the three and nine months ended September 30, 2021 were $7.2 million and negative $31.9 million, respectively. These relate primarily to the remeasurement of previously recognized decommissioning and restoration liabilities at our Peru and Manitoba operations as a result of changing discount rates.

Capital Commitments

As at September 30, 2021, we had outstanding capital commitments in Canada of approximately $50.5 million of which $41.0 million can be terminated, approximately $41.6 million in Peru primarily related to exploration option agreements, all of which can be terminated, and approximately $181.0 million in Arizona, primarily related to our Rosemont project, of which approximately $88.9 million can be terminated.

For further information and a detailed reconciliation, please see the discussion under the "Non-IFRS Financial Reporting Measures" section of this MD&A.

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

Commodity prices have steadily increased since the second quarter of 2020 to what is currently their highest levels in many years. Other than one-time charges, our revenues, gross profit and operating cash flow have steadily improved with the rise in commodity prices.

During the third quarter of 2021, we continued to realize higher base metal prices resulting in elevated revenues and operating cash flow. Mining at Pampacancha has continued to ramp-up, contributing significantly to gold production during the quarter. As a result of the planned closure of Flin Flon operations in mid-2022 and an updated Flin Flon closure plan, non-cash charges totaling $156.3 million were incurred, which negatively impacted gross profit for the quarter. In Peru, ongoing COVID-19 costs, along with lower copper grades, have put pressure on operating costs.

Financial results in the second quarter of 2021 benefited from initial production at the Pampacancha pit but were negatively impacted by higher operating costs in Peru and lower Manitoba metal production caused by COVID-19 related impacts as well as lower copper and zinc grades and lower precious metal recoveries.

The first quarter of 2021 saw lower revenues compared to the fourth quarter of 2020 due to a delayed Peru 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. First quarter results were negatively impacted by $75.2 million of various finance expenses related to the refinancing of our senior notes.

We experienced production disruptions during the first half of 2020 due to an eight-week suspension of Constancia operations in Peru from a government declared state of emergency and at the 777 mine during the fourth quarter of 2020 due to a six-week interruption to perform repairs following a skip hoist incident. However, the deferral of production and sales that arose from these disruptions allowed us to benefit from increasing commodity prices. The reduced copper production from Constancia and 777 in 2020 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 first and second quarter of 2020 were impacted by the temporary suspension of operations at Constancia, which resulted in $31.9 million in certain overhead costs being expensed. For information on previous trends and quarterly reviews, refer to our MD&A for the year ended December 31, 2020, dated February 18, 2021.

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 addition, during the third quarter of 2021, there were non-recurring adjustments for Manitoba operations, including severance, past service pension costs, write-downs of certain machinery and equipment, and inventory supplies write-downs as well as a non-cash impairment charges related to an updated Flin Flon closure plan, none of which management believes are indicative of the ongoing operating performance and have therefore been excluded from the calculations of adjusted net earnings (loss) and adjusted EBITDA.

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 and nine months ended September 30, 2021 and 2020.

^2^ Includes severance accrued for unionized employees and write down of materials and supply inventories at the Flin Flon operations.

After adjusting reported net earnings for those items not considered representative of the Company's core business or indicative of future operations, the Company had an adjusted net earnings in the third quarter 2021 of $38.2 million or $0.15 earnings 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 and nine months ended September 30, 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 and nine months ended September 30, 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 and nine months ended September 30, 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 and nine months ended September 30, 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 September 30, 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 September 30, 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 September 30, 2021 that materially affected or are reasonably likely to materially affect our ICFR.

Hudbay Announces Third Quarter 2021 Results

Toronto, Ontario, November 3, 2021 - Hudbay Minerals Inc. ("Hudbay" or the "company") (TSX, NYSE:HBM) today released its third quarter 2021 financial results. All amounts are in U.S. dollars, unless otherwise noted.

Third Quarter Operating and Financial Results

Generated $359.0 million in revenue, $103.5 million of operating cash flow before change in non-cash working capital and $119.3 million of adjusted EBITDA^i^ in the third quarter of 2021 from higher realized base metals prices and higher gold sales volumes, partially offset by lower base metals sales volumes.
Consolidated copper production in the third quarter was 23,245 tonnes; quarterly consolidated gold production increased by 35% to 53,872 ounces in the third quarter, compared to the second quarter in 2021, a record for Hudbay.
Consolidated cash cost and sustaining cash cost per pound of copper produced, net of by-product credits^i^, were $0.62 and $1.97, respectively, an improvement of 26% and 12% compared to the second quarter of 2021.
Third quarter Peru production was boosted by significantly higher gold grades from Pampacancha and record gold recoveries, leading to record quarterly gold revenue. Pampacancha production continues to ramp-up, achieving a 109% increase in ore production quarter over quarter.
Third quarter Manitoba production benefited from higher throughput and higher gold grades at Lalor but was negatively impacted by lower zinc grades and zinc recoveries, limiting overall zinc concentrate feed to the zinc plant. Manitoba results included initial gold production from New Britannia's gold circuit.
On track to meet annual production guidance for copper, gold, zinc and silver in concentrate and doré, consolidated sustaining capital expenditures, and Manitoba unit operating cost in 2021. After adjusting for unbudgeted COVID-related costs in Peru, full year unit operating costs for Peru are expected to be around the top end of the 2021 guidance range.
Third quarter net loss and loss per share were $170.4 million and $0.65, respectively. After normalizing for an impairment charge related to higher estimated closure costs associated with the company's updated Flin Flon closure plan and the Flin Flon restructuring charges, amongst other items, third quarter adjusted net earnings^i^ per share were $0.15.
Cash and cash equivalents increased during the third quarter to $297.5 million as at September 30, 2021, mainly as a result of $139.8 million of cash generated from operations, partially offset by $89.1 million of capital investments primarily for the construction of the New Britannia project and sustaining capital expenditures, and $33.6 million of interest paid on the company's senior unsecured notes.

Executing on Growth Initiatives

New Britannia has achieved project completion as construction activities at the new copper flotation facility concluded in October. Refurbishment and commissioning activities at the gold mill were completed in July 2021, and the mill achieved first gold production on August 11, 2021. Commissioning of the copper circuit was completed and first production of concentrate was achieved in October, ahead of the original schedule, while ramp-up activities at the flotation plant continue. Annual gold production from Lalor and the Snow Lake operations is on track to increase to over 180,000 ounces at an average cash cost and sustaining cash cost, net of by-product credits, of $412 and $788 per ounce of gold, respectively, during the first six full years of operation starting in 2022.

TSX, NYSE - HBM<br><br> <br>2021 No. 23

Mining activities at the Pampacancha satellite pit continue to advance as planned with grades and tonnes reconciling well against the mine plan, achieving the expected increase in gold grades in 2021 and on track for achieving higher copper grades in 2022, in line with recent company guidance.
Recent Copper World drilling has identified three new deposits for a total of seven distinct deposits with a combined strike length of over seven kilometres. The company remains on track to complete an initial inferred resource estimate before the end of the year and a preliminary economic assessment in the first half of 2022.
Scoping study planned for 2022 to examine the opportunity to reprocess tailings in Flin Flon after the closure of the 777 mine, which could further increase metal production, defer closure costs and reduce the environmental footprint of the tailings facility.
Amended and restated Hudbay's senior secured revolving credit facilities to increase available borrowings to $450 million and enhance the company's financial flexibility, while extending the maturity to 2025.

"Our third quarter performance demonstrates our continued focus on execution and delivery in 2021 as we enjoyed the first full quarter of Pampacancha production and we started to see the benefits of higher gold from the New Britannia mill," said Peter Kukielski, President and Chief Executive Officer. "We also recently commissioned the new copper flotation circuit at New Britannia, ahead of our expected timelines. With the completion of the Pampacancha and New Britannia growth projects, we are on the cusp of achieving significantly increased cash flows from these high-return investments for many years to come. We are also very pleased to have continued exploration success at our Copper World project and look forward to advancing the opportunity for a private land operation in Arizona to unlock further value for our stakeholders."

Summary of Third Quarter Results

Cash generated from operating activities in the third quarter of 2021 increased to $139.8 million, compared to $96.4 million in the second quarter and $51.8 million in the first quarter of 2021. Operating cash flow before change in non-cash working capital was $103.5 million during the third quarter of 2021, reflecting a decrease of $29.3 million compared to the second quarter of 2021, primarily as a result of lower base metals sales volumes and lower realized copper and precious metals prices, partially offset by higher precious metals sales volumes.

Consolidated copper production in the third quarter of 2021 was 23,245 tonnes, generally in-line with the second quarter of 2021 as slightly lower copper production in Peru was offset by higher copper production in Manitoba. Consolidated gold production in the third quarter of 2021 was 53,872 ounces, a quarterly record for Hudbay and a 35% increase from the second quarter of 2021, due to higher gold grades from Pampacancha and record gold recoveries in Peru, along with significantly higher gold grades at Lalor. Zinc production in the quarter was 20,844 tonnes, a slight decrease from the second quarter as production volumes were lower in Flin Flon. Consolidated silver production increased to 763,168 ounces, an 11% increase versus the second quarter of 2021, primarily due to higher silver grades milled in Peru and Snow Lake.

In the third quarter of 2021, consolidated cash cost per pound of copper produced, net of by-product credits^i^, was $0.62, compared to $0.84 in the second quarter of 2021. This 26% decrease was mainly a result of lower operating costs. Sustaining cash cost per pound of copper produced, net of by-product credits^i^, decreased to $1.97 in the third quarter of 2021, from $2.25 in the second quarter, primarily due to the same factors affecting cash cost as well as slightly lower sustaining capital expenditures. Consolidated cash cost and sustaining cash cost per pound of copper produced, net of by-product credits, are expected to remain within the guidance ranges for 2021.

TSX, NYSE - HBM<br><br> <br>2021 No. 23

Net loss and loss per share in the third quarter of 2021 were $170.4 million and $0.65, respectively, compared to a net loss and loss per share of $3.4 million and $0.01, respectively, in the second quarter of 2021. Third quarter results were negatively impacted by an updated closure plan reflecting higher estimates for closure activities in Flin Flon, primarily related to water treatment costs. The higher closure cost estimate has resulted in an increase to the company's environmental obligation and a corresponding increase to Flin Flon's property plant and equipment. However, as the closure of Flin Flon is expected to commence within 12 months, an impairment charge was made resulting in a loss of $147.3 million. The quarterly financial results were also negatively impacted by Flin Flon restructuring charges comprising an inventory supplies write down of $5.4 million and a severance accrual of $3.6 million for unionized employees, as well as an increase in past service pension cost provision of $4.2 million related to pensions for Manitoba unionized employees.

Adjusted net earnings^i^ and adjusted net earnings per share^i^ in the third quarter of 2021 were $38.2 million and $0.15 per share after normalizing for an impairment due to the updated Flin Flon closure plan and the Flin Flon restructuring charges, among other items. This compares to adjusted net earnings and adjusted net earnings per share of $5.4 million and $0.02 per share in the second quarter of 2021. Third quarter adjusted EBITDA^i^ was $119.3 million, compared to $143.2 million in the second quarter of 2021, primarily due to lower base metal sales volumes and lower realized copper and precious metals prices, partially offset by higher precious metals sales volumes.

As at September 30, 2021, Hudbay's liquidity includes $297.5 million in cash and cash equivalents as well as undrawn availability of $297.3 million under its credit facilities. The company's liquidity position was further enhanced in October through the successful renegotiation of the credit facilities to increase available borrowings to $450 million, while extending the maturity to 2025.

While Peru has experienced notable improvements in COVID-19 statistics throughout 2021, Hudbay continues to maintain stringent COVID-19 measures and controls to ensure the safety of its workforce, partners and the communities in which the company operates. This has allowed Constancia to continue to operate safely although it has resulted in elevated unit operating costs due to the ongoing COVID-related protocols.

TSX, NYSE - HBM<br><br> <br>2021 No. 23

During the third quarter 2021, the Constancia operations produced 18,072 tonnes of copper, 17,531 ounces of gold, 521,036 ounces of silver and 282 tonnes of molybdenum. While copper production was 5% lower than the second quarter due to a planned semi-annual mill maintenance shutdown in July, gold and silver production increased by 72% and 11%, respectively, due to significantly higher gold and silver head grades from Pampacancha and significantly higher gold recoveries. This was a record quarter for gold production, grades and recoveries in Peru. Other than molybdenum, which is expected to fall slightly below the 2021 guidance range but in-line with the recently published mine plan, Hudbay expects the production of all other metals in Peru to be in line with the 2021 full year guidance.

Total ore mined during the third quarter of 2021 decreased by 8% from the second quarter of 2021 as mining levels were optimized for mill throughput. Ramp-up of mining activity at Pampacancha has increased steadily since first production in April 2021. Total Pampacancha ore mined during the third quarter increased by 109% to 2.1 million tonnes compared to the second quarter of 2021. Tonnes of ore milled during the third quarter of 2021 were 6% lower than the second quarter of 2021 due to the scheduled mill maintenance shutdown. Milled grades for copper were slightly lower than the second quarter but were in line with the mine plan. Milled grades for gold and silver were 57% and 36% higher, respectively, than the second quarter due to significantly higher precious metal head grades from Pampacancha.

Peru achieved record gold recoveries in the third quarter of 2021, significantly above the second quarter of 2021, mainly due to higher grades from Pampacancha. Meanwhile, copper recoveries increased due to lower levels of contaminants and silver recoveries decreased as a result of lower-than-expected recoverable silver values in the earlier, more oxidized ores from Pampacancha. Recent metallurgical test work indicates that Pampacancha silver recoveries are expected to increase to targeted levels in 2022.

Combined mine, mill and G&A unit operating costs in the third quarter of 2021 were $11.62 per tonne, compared to $11.25 in the second quarter of 2021, primarily due to higher milling costs and fewer tonnes milled due to the scheduled mill maintenance program during the quarter. Costs have been generally higher in 2021 as a result of higher ore hardness, higher steel prices affecting grinding media costs, higher fuel prices impacting hauling costs and COVID-19 expenditures. COVID-related costs in Peru were $4.8 million in the third quarter and are expected to continue at a similar run-rate into the fourth quarter of 2021. Unit operating costs in the third quarter were $10.93 per tonne excluding these COVID-related costs. Hudbay expects Peru unit operating costs to be around the top end of the 2021 guidance range after adjusting for unbudgeted COVID-related costs.

Peru's cash cost per pound of copper produced, net of by-product credits, in the third quarter of 2021 was $1.26, a 32% improvement over the second quarter. The significant reduction in cash cost was due to higher by-product credits and lower operating costs, partially offset by lower copper production. Peru's sustaining cash cost per pound of copper produced, net of by-product credits, in the third quarter of 2021 decreased to $2.31, compared to $2.69 in the second quarter of 2021, due to same factors noted above affecting cash costs, offset by higher sustaining capital expenditures.

TSX, NYSE - HBM<br><br> <br>2021 No. 23

As the Manitoba business started to see the benefits from the commencement of gold production at the New Britannia mill, production of copper, gold and silver increased during the third quarter, compared to the second quarter of 2021, while production of zinc decreased. Production during the quarter included 5,173 tonnes of copper, 36,745 ounces of gold, 242,141 ounces of silver and 20,844 tonnes of zinc. Hudbay expects the production of all metals contained in concentrate and doré in Manitoba to be in line with the 2021 full year guidance.

Ore mined at the Manitoba operations during the third quarter of 2021 was higher than the second quarter of 2021 due to higher production rates at Lalor. Copper and gold grades were higher compared to the previous quarter, mainly due to increased mining of gold and copper-gold stopes at Lalor, in line with the mine plan. Mined zinc grades were lower than the previous quarter as mining of the gold zones at Lalor were prioritized during the quarter.

During the third quarter of 2021, New Britannia processed 41,827 tonnes of high gold content ore and produced 404 ounces of gold in doré after pouring its first doré bar on August 11. The gold and silver recoveries are expected to increase in the fourth quarter after ramp-up of the mill during the third quarter. Construction of the new copper flotation circuit was completed in October 2021, followed by a brief commissioning period completed ahead of schedule. Ramp-up activities at the copper circuit are underway and are on track for completion in the fourth quarter of 2021.

Ore processed at the Stall concentrator and New Britannia mill during the third quarter was 29% higher than the second quarter. Combined Stall and New Britannia recoveries during the third quarter of 2021 were higher for zinc and lower for copper, gold and silver, versus the previous quarter, but were consistent with expectations as the third quarter was a partial ramp-up period for the New Britannia mill. Operations at the Flin Flon concentrator during the third quarter were constrained by ore feed availability from 777 and, as such, ore processed decreased by 22% compared to the second quarter of 2021. Recoveries of copper, gold and silver at the Flin Flon concentrator during the second quarter of 2021 were higher than the previous quarter mainly due to higher copper head grades from the 777 mine, consistent with the metallurgical model.

Combined mine, mill and G&A unit operating costs in the third quarter of 2021 slightly decreased compared to the second quarter of 2021. Hudbay expects Manitoba unit operating costs in 2021 to be in line with the annual guidance range.

Manitoba's cash cost per pound of copper produced, net of by-product credits, for the third quarter of 2021 was negative $1.64, higher than the second quarter primarily due to lower by-product credits, partially offset by lower onsite costs. Manitoba's sustaining cash cost per pound of copper produced, net of by-product credits, in the third quarter of 2021 was $0.75 compared to $0.36 in the second quarter, primarily due to the same reasons listed above, offset by lower comparative sustaining capital expenditures.

COVID-19 Business Update

On a population adjusted basis, Hudbay continues to see a steady decline in the number of new cases of COVID-19 in the regions in which it operates. Despite these encouraging declines, the company is maintaining stringent COVID-19 measures and controls to ensure the safety of its workforce, partners and communities. As such, the company continues to experience an ongoing financial and, to a lesser extent, operating impact from COVID-19.

New Britannia First Gold Production Achieved and Copper Flotation Facility Fully Commissioned

Advancing the Copper World Discovery

On September 22, 2021, the results from drilling completed at Copper World between January and June 2021 were released. The drill program totaled over 91,000 feet and intersected additional high-grade copper sulphide and oxide mineralization on the company's wholly-owned private land in Arizona. The Copper World project is located within seven kilometres of the Rosemont copper project and has mineralization located closer to surface than Rosemont, indicating the possibility of lower strip ratios at Copper World. Hudbay recently increased its private land package to approximately 2,400 acres in the west, which together with patented mining claims, now totals approximately 4,500 acres to support an operation entirely on private land.

There remains the potential for continuity between the Bolsa discovery and the Rosemont deposit as highlighted by three new holes drilled on the western edge of Rosemont, which intersected high-grade copper mineralization similar to the mineralization intersected at Bolsa. For example, drill hole #177 intersected 833 feet of 0.40% copper, including 121 feet at 1.32% copper (please refer to the news release dated September 22, 2021 for additional drill hole information). There remains a 1,500-foot gap in drilling coverage between these three holes and the Bolsa discovery, and the company is developing plans to test this unexplored area.

Given the continued positive results from the exploration program at Copper World, the 2021 drill program was previously expanded from an original 70,000 feet of drilling to over 200,000 feet to be completed by the end of the year with four drill rigs continuing to operate at site. Hudbay is testing the opportunity to use reverse circulation drilling to fast-track future infill drilling programs. This drilling is intended to delineate and upgrade the resource for the seven deposits, while focusing on bridging the gap between the Bolsa discovery and the area west of the Rosemont deposit. The drill program will also continue to explore prospective areas outside of the known deposits.

TSX, NYSE - HBM<br><br> <br>2021 No. 23

Hudbay expects to complete an initial inferred mineral resource estimate for the seven deposits at Copper World before the end of 2021. These mineral resource estimates will form the basis for a preliminary economic assessment ("PEA") expected to be released in the first half of 2022. Mineralogical studies and metallurgical testing programs are underway, and the preliminary results are expected to be incorporated into the PEA. Hudbay continues to progress geotechnical and hydrogeological studies over the Copper World area.

In October, Hudbay received approval from the Arizona State Mine Inspector for its Mined Land Reclamation Plan ("MLRP") for Copper World. The MLRP approval includes the requirement for reclamation cost bonding prior to initiating work on the company's private lands and represents the first step in the state-level permitting process for a private land operation.

The budget for Copper World in 2021 is expected to total approximately $34 million, which increased from the original $10 million budget, to fund the larger drill program and complete the various technical studies. Hudbay will also continue to examine future potential synergies with an operation at Rosemont.

Other Exploration Updates

Peru Regional Exploration

Hudbay continues to progress discussions with the community of Uchucarcco on the Maria Reyna and Caballito properties, both of which are located within ten kilometres of Constancia.

Snow Lake Regional Exploration

The company's regional exploration efforts in the Snow Lake area continue, following on the success from the 2021 winter drill program in the Chisel Basin where the copper-gold rich feeder of the 1901 deposit was discovered and high-grade zinc and gold mineralization was confirmed through infill and extension drilling. A 2022 drill program is planned for 1901 to test the down-plunge extensions of the copper-gold rich feeder zone.

TSX, NYSE - HBM<br><br> <br>2021 No. 23

Ongoing infill drilling continues at Lalor and the results are expected to be incorporated into the annual mineral reserve and resource estimates to be published at the end of March 2022.

Flin Flon Reclamation Obligations and Tailings Reprocessing Opportunity

As part of the company's ongoing efforts to update its Flin Flon closure plan, a comprehensive update completed in the third quarter of 2021 resulted in an increase to the decommissioning and restoration ("DRO") provision of approximately $144 million compared to June 30. This increase is mostly attributable to long-term water treatment and monitoring obligations, along with cost inflation for other remediation activities. The increase in water management costs is primarily a result of the addition of 22 years to the post-closure water management period (to the year 2122), which after applying a very low discount rate, represents a significant portion of the DRO increase. As of September 30, 2021, on an undiscounted basis, the total estimated environmental obligations related to the company's Flin Flon operations were $322 million, of which approximately 25% is expected to occur over the next 15 years in connection with the closure of the Flin Flon operations, while approximately 75% of the obligations are scheduled to be incurred after the closure of the Snow Lake operations, which is currently expected in 2037 based on reserves. The full breakdown is as follows:

$23 million for previously announced tailings stability activities that will be completed in 2021 and 2022;
$13 million for demolition costs between the cessation of operations in Flin Flon and 2030;
$33 million for the construction and operation of a water treatment plant between 2030 and 2042;
$46 million for demolition and tailings remediation costs after Snow Lake mining activities conclude in 2037 (based on current reserves) until 2042;
$161 million in post-closure environmental management activities (such as water collection and treatment) from 2037 to 2122; and
$46 million in other site management costs and remediation activities.

As part of the engineering work done to update the closure plan, Hudbay has identified the opportunity to reprocess tailings at its Flin Flon Tailings Impoundment System ("FFTIS") where tailings from processing activities in Flin Flon have been deposited for over 90 years. The company is in the early stages of technical evaluation and confirmatory drilling to support the completion of a scoping study in 2022. Pending positive results from the scoping study, further feasibility studies would follow. This opportunity could utilize the Flin Flon concentrator, with modifications, after closure of the 777 mine, creating operating and economic benefits to the Flin Flon community. It could also provide the opportunity to redesign the closure plans, increase metal production, defer certain closure costs and reduce the environmental footprint of the FFTIS.

Collective Bargaining Agreements Ratified in Manitoba

Credit Facility Extension and Amendments

On October 26, 2021, Hudbay amended and restated its senior secured revolving credit facilities (the "Credit Facilities") to increase the total amount of available borrowings to $450 million, eliminate certain financial covenants while amending others to increase the company's financial flexibility, reduce the effective interest rate and extend the maturity to October 26, 2025. The remaining financial covenants include maintaining a net debt to EBITDA ratio of less than 4.00:1, a senior secured debt to EBITDA of less than 3.00:1 and an interest coverage ratio of greater than 3.00:1.

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.

TSX, NYSE - HBM<br><br> <br>2021 No. 23

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.

The following tables provide detailed reconciliations to the most comparable IFRS measures.
