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, 2020 and 2019 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, 2020 include HudBay Marketing & Sales Inc. ("HMS"), HudBay Peru Inc., HudBay Peru S.A.C. ("Hudbay Peru"), HudBay (BVI) Inc., Hudbay Arizona Inc, Rosemont Copper Company ("Rosemont") and Mason Resources (US) Inc ("Mason").

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

2. Basis of preparation

(a)   Statement of compliance:

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

These interim financial statements should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2019 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, 2019 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, 2020.

HUDBAY MINERALS INC.<br><br> <br>Notes to Unaudited Condensed Consolidated Interim Financial Statements<br><br> <br>(in thousands of US dollars, except where otherwise noted)<br><br> <br>For the three and nine months ended September 30, 2020 and 2019

(b)  COVID-19 estimation uncertainty:

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

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

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

(c)   Use of judgements and estimates:

The preparation of the interim financial statements in conformity with IFRS requires Hudbay to make judgements, estimates and assumptions, in applying accounting policies that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim financial statements, as well as reported amounts of revenue and expenses during the reporting period. Actual results may differ from these judgements, estimates and assumptions. The interim financial statements reflect the judgements and estimates outlined by Hudbay in its audited consolidated financial statements for the year ended December 31, 2019.

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, 2019 and comparative periods.

4. New standards

New standards and interpretations adopted

(a)  Amendment to IFRS 3 - Business Combinations

The amendment to IFRS 3 clarifies the definition of a business and includes an optional concentration test to determine whether an acquired set of activities and assets is a business. This amendment is in effect January 1, 2020 and will be treated prospectively. Hudbay will apply these amendments to future acquisition transactions.

New standards and interpretations not yet adopted

(b)  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 that assets to the location and condition necessary for it 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 is currently working on determining  the effect of the adoption of this amendment on its consolidated financial statements, specifically to projects expected to achieve commercial production in the coming years. On adoption, an entity applies the amendments retrospectively 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 the beginning of the earliest period presented in the financial statements in which the entity first applies the amendments.

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 2020 and amendments made to the 777 mine plan in the third quarter of 2020, 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 for the three and nine months ended September 30, 2020 resulted in increased revenue of $9,482 and $6,668, respectively. This increase in revenue was primarily the result of internal business planning and amendments in the 777 mine plan resulting in mining less of the inferred resource than what was previously planned. The variable consideration adjustment for the nine months ended September 30, 2019 resulted in a reversal of revenue of $16,295.

During the first quarter of 2019, Hudbay recognized an obligation to deliver additional precious metal credits to Wheaton Precious Metals ("Wheaton") as a result of Hudbay's expectation that mining at the Pampacancha deposit will not begin until after 2020. The obligation is to be paid in four quarterly installments, with the first three payments having been paid in March, June and September 2020.

(e) Impairmen****t

For the third quarter ended September 30, 2020, Hudbay recorded no impairment losses.

During the third quarter ended September 30, 2019, Hudbay recorded impairment losses of $322,249 for non-current assets relating to the Arizona cash generating units ("CGU").

Arizona
Pre-tax impairment to:
Property, plant & equipment $ 322,249
Tax impact - (recovery) (80,143 )
After-tax impairment charge $ 242,106

On July 31, 2019 the U.S. District Court of the District of Arizona ("Court") issued a ruling in the lawsuits challenging the U.S. Forest Service's issuance of the Final Record of Decision ("FROD") for the Rosemont project in Arizona. The Court ruled to vacate and remand the FROD thereby delaying the expected start of construction of Rosemont. Hudbay and the U.S. federal government have appealed the Court's decision to the U.S. Ninth Circuit Court of Appeals. However, the Court's ruling and the subsequent impact to the Company's market capitalization gave rise to an indicator of impairment. Following an impairment test conducted as of September 30, 2019, it was determined that the recoverable amount of the Arizona CGU was lower than its carrying value, causing Hudbay to recognize an impairment loss related to these assets.

Until October 1, 2019, interest expense related to certain long-term debt had been capitalized to the Rosemont project. Following the Court ruling to vacate and remand the U.S. Forest Service's issuance of the Final Record of Decision for the Rosemont project during the third quarter of 2019, Hudbay ceased capitalization effective October 1, 2019. The capitalization of this interest expense will resume upon the reinstatement of permits and will continue from that point until commercial production is reached.

Other finance expense relates primarily to fees on Hudbay's revolving credit facilities and capitalized leases.

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 $21,475 (December 31, 2019 - $10,411) includes $16,528 of other assets (December 31, 2019 - $5,384) and $4,947 of intangibles (December 31, 2019 - $5,027).

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 (note 5d). The increase in other assets during the nine months ended September 30, 2020 primarily relates to amendments to the original agreements with communities for the Constancia operation which allow Hudbay to extract minerals over the useful life of the Constancia operation.

Intangibles mainly represent computer software costs.

Derivative liabilities are carried at their fair value with changes in fair value recorded to the condensed consolidated interim income statements. The fair value adjustments for hedging type derivatives are recorded in revenue. Fair value adjustments for embedded derivatives are recorded within net finance expense.

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 fair value adjustment recorded in profit or loss and other comprehensive income for the nine months ended September 30, 2020 were losses of $16,735 and $277, 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 increase in other financial liabilities at amortized cost during the nine months ended September 30, 2020 primarily relates to changes in estimated community payments arising from the execution of the Pampacancha surface rights agreement.

$ 78,905 $ 88,096

Hudbay has entered into leases for its Peru, Manitoba and Arizona business units which expire between 2020 and 2043. The interest rates on leases which were capitalized have implicit interest rates between 1.95% to 5.13%, per annum. The range of interest rates utilized for discounting varies depending mostly on the Hudbay entity acting as lessee and duration of the lease. For certain leases, Hudbay has the option to purchase the equipment and vehicles leased at the end of the terms of the leases. Hudbay's obligations under these leases are secured by the lessor's title to the leased assets. The present value of applicable lease payments has been recognized as a ROU asset, which was included as a non-cash addition to property, plant and equipment, and a corresponding amount as a lease liability.

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

The following outlines expenses recognized within the Company's condensed consolidated interim income statements for the periods ended September 30, 2020, relating to leases for which a recognition exemption was applied.

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

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 statement (note 5f).

As at September 30, 2020, $1,200,000 aggregate principal amount of senior notes were outstanding in two series: (i) a series of 7.625% senior notes due 2025 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.

The senior notes are guaranteed on a senior unsecured basis by substantially all of the Company's subsidiaries, other than HudBay (BVI) Inc. and certain excluded subsidiaries, which include the Company's subsidiaries that own an interest in the Rosemont project and any newly formed or acquired subsidiaries that primarily hold or may develop non-producing mineral assets that are in the pre-construction phase of development**.** Hudbay's revolving credit facilities are secured against substantially all of the Company's assets, other than those associated with the Arizona business unit.

On August 31, 2020, Hudbay completed a restructuring of its two senior secured credit facilities. The total available credit has been reduced from $550,000 to $400,000 and various financial covenants have been amended.

The unamortized transaction costs of $1,502 were expensed upon restructuring of the credit facilities.

As at September 30, 2020, the Peru business unit had $24,795 in letters of credit issued under the Peru revolving credit facility to support its reclamation obligations and the Manitoba business unit had $83,795 in letters of credit issued under the Canada revolving credit facility to support its reclamation and pension obligations. As at September 30, 2020, there were no cash advances under the credit facilities.

Surety bonds

The Arizona business unit had $8,591 in surety bonds and the Peru business unit had $20,000 in surety bonds, issued to support future reclamation and closure obligations. No cash collateral is required to be posted under these surety bonds.

Other letters of credit

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 the Constancia mine.

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

Hudbay recorded the deposits received as deferred revenue and recognizes amounts in revenue as gold and silver are delivered under the stream agreements. Hudbay determines the amortization of deferred revenue to the condensed consolidated interim income statements on a per unit basis using the estimated total number of gold and silver ounces expected to be delivered under the stream agreements over the life of the 777 and Constancia life-of-mine plans. At September 30, 2020, Hudbay revised its estimate of remaining mineralization for the 777 deposit and as such adjusted the drawdown rates for the remainder of the year. For the nine months ended September 30, 2020 the drawdown rates for the 777 stream agreement for gold and silver were $1,155 and $22.07 per ounce, respectively (year ended December 31, 2019 - $1,177 and $22.51 per ounce, respectively). For the nine months ended September 30, 2020 the drawdown rates for the Constancia stream agreement for gold and silver were $976 and $21.52 per ounce, respectively (year ended December 31, 2019 - $948 and $21.77 per ounce, respectively). Hudbay estimates the current portion of deferred revenue based on deliveries anticipated over the next twelve months.

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

Hudbay expects that the remaining performance obligations for the 777 and Constancia streams will be settled by the expiry of their respective stream agreements, which is no earlier than 2036.

As part of the streaming agreement for the 777 mine, Hudbay must repay, with precious metals credits, the legal deposit provided by August 1, 2052, the expiry date of the agreement. If the legal deposit is not fully repaid with precious metals credits from 777 production by the expiry date, a cash payment for the remaining amount will be due at the expiry date of the agreement. Given the mineral reserve and resources of the 777 mine and the current mine plan, there is a possibility that an amount of the legal deposit may not be repaid by means of 777 mine's precious metals credits over its expected remaining mine life. As at September 30, 2020, this prepayment amount does not meet the definition of a financial liability. Hudbay incorporates the possibility of repayment as part of its assessment of variable consideration in recognizing the amount of deferred revenue to recognize in income.

The following table summarizes changes in deferred revenue:

Balance, January 1, 2019 $ 566,078
Amortization of deferred revenue
Liability drawdown (92,398 )
Variable consideration adjustments - prior periods 16,295
Accretion on streaming arrangements

Variable consideration adjustments - prior periods 6,047
Effects of changes in foreign exchange 4,009

Current year additions 46,508
Variable consideration adjustments - prior periods (3,692 )
Effects of changes in foreign exchange (2,171 )
Balance, September 30, 2020 $ 550,581

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 2020 and amendments made to the 777 mine plan in the third quarter of 2020, 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 $6,668 and reversal of finance expense of $3,692 for the nine months ended September 20, 2020 (December 31, 2019 - revenue reversal of $16,295 and additional finance expense $6,047).

During the nine months ended September 30, 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. During the year ended December 31, 2019, and first quarter of 2020, the Company recognized an adjustment to gold and silver revenue and finance costs.

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

Sep. 30, 2020 Dec. 31, 2019
Current $ 73,296 $ 86,933
Non-current 477,285 476,823

16. Provisions

Reflected in the condensed consolidated interim balance sheets as follows:

Sep. 30, 2020 Decommissioning, restoration and similar liabilities Deferred share units Restricted share units Performance share units Other Total
Current (note 11) $ 21,327 $ 4,979 $ 2,478 $ - $ - $ 28,784
Non-current 318,995 - 2,710 831 1,344 323,880
$ 340,322 $ 4,979 $ 5,188 $ 831 $ 1,344 $ 352,664
Dec. 31, 2019 Decommissioning, restoration and similar liabilities Deferred share units Restricted share units Performance share units Other Total
Current (note 11) $ 23,621 $ 3,876 $ 4,468 $ - $ 1,610 $ 33,575
Non-current 278,495 - 1,009 - 1,346 280,850
$ 302,116 $ 3,876 $ 5,477 $ - $ 2,956 $ 314,425

Decommissioning, restoration and similar liabilities 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.

Decommissioning, restoration and similar liabilities have been discounted to their present value at rates ranging from 0.13% to 1.46% per annum (2019 - 1.59% to 2.39%), using pre-tax risk-free interest rates that reflect the estimated maturity of each specific liability.

During the nine months ended September 30, 2020, the decommissioning, restoration and similar liabilities increased by $38,206. This was mainly the result of lower discount rates, compared to December 31, 2019, associated with discounting the provisions, increasing the liabilities by $52,972, which was partially offset by payments of $13,766 and a weaker Canadian dollar impacting the liabilities of the Manitoba segment by $4,183.

17. Pension and other employee benefits

Pension obligations

Hudbay uses a December 31 measurement date for all of its plans. As at September 30, 2020, the discount rate applied to the most recent actuarial valuation decreased to 2.67% compared to the December 31, 2019 discount rate of 3.08%, reflecting lower corporate bond yields utilized for discounting pension liabilities. The decrease in the discount rate has resulted in an increase in the defined benefit pension obligation which was offset by changes in plan assets.

Other employee benefits

Hudbay sponsors both other long-term employee benefit plans and non-pension post-employment benefits plans and uses a December 31 measurement date. As at September 30, 2020, the discount rate applied to the most recent actuarial valuation decreased to 2.88% compared to the December 31, 2019 discount rate of 3.17%, reflecting lower corporate bond yields utilized for discounting other employee benefit liabilities. The decrease in the discount rate has resulted in an increase in the long-term employee benefit plans and non-pension post-employment benefit plans obligation.

Net deferred tax liability balance, end of period $ (135,451 ) $ (167,882 )

Hudbay has retroactively changed its presentation of deferred tax assets and liabilities to separate out the Canadian mining tax assets and liabilities, which has the effect of changing the prior reported balances of deferred tax assets and deferred tax liabilities. There is no net impact to cash flows or net deferred tax liabilities.

(c) Equity-settled share-based compensation - stock options:

Hudbay may grant options to employees, officers, directors or consultants of Hudbay or its affiliates to purchase common shares of Hudbay.

During the nine months ended September 30, 2020, the Company granted 1,581,385 stock options (nine months ended September 30, 2019 - nil). The following table presents the weighted average fair value assumptions used in the Black-Scholes valuation of these options:

For options granted during the nine months ended: Sep. 30, 2020
Weighted average share price at grant date (CAD) $ 3.77
Risk-free rate 1.14%
Expected dividend yield 0.5%
Expected stock price volatility (based on historical volatility) 57.0%
Expected life of option (months) 84
Weighted average per share fair value of stock options granted (CAD) $ 2.02

During the nine months ended September 30, 2020, 12,052 stock options were forfeited, which resulted in 1,569,333 options outstanding as of September 30, 2020. There are no stock options outstanding that are exercisable as at September 30, 2020.

20. Earnings per share

Three months ended <br>September 30, Nine Months Ended<br>September 30,
2020 2019 2020 2019
Basic and diluted weighted average common shares outstanding 261,272,151 261,272,151 261,272,151 261,272,151

The determination of the diluted weighted-average number of common shares excludes the impact of 1,574,357 and 1,506,625 weighted-average stock options outstanding that were anti-dilutive for the three and nine months ended September 30, 2020 (three and nine months ended September 30, 2019 - nil).

For periods where Hudbay records a loss, Hudbay calculates diluted loss per share using the basic weighted average number of shares. If the diluted weighted average number of shares were used, the result would be a reduction in the loss, which would be anti-dilutive. For the three and nine months ended September 30, 2020 and 2019, Hudbay calculated diluted loss per share using 261,272,151 common shares.

1 Cash and cash equivalents, restricted cash, trade and other receivables and trade and other payables are recorded at carrying value, which approximates fair value due to their short-term nature and generally negligible credit losses.
2 Excludes tax and other statutory amounts.
3 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.
4 All investments are carried at their fair value, which is determined using quoted market bid prices in active markets for listed shares.
5 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.
6 Fair value of the senior unsecured notes (note 14) has been determined using the quoted market price at the period end.
7 Fair value of the prepayment option embedded derivative related to the long-term debt (note 14) 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, 2020 was a loss of 277.

All values are in US Dollars.

Fair value hierarchy

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

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

  • Level 2: Valuation techniques use significant observable inputs, either directly or indirectly, or

valuations are based on quoted prices for similar instruments; and,

  • Level 3: Valuation techniques use significant inputs that are not based on observable market

data.

Hudbay's policy is to recognize transfers into and transfers out of fair value hierarchy levels as of the date of the event or change in circumstances that caused the transfer. During the three and nine months ended September 30, 2020 and 2019 Hudbay did not make any 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, 2020, Hudbay had 57.3 million pounds of net copper swaps outstanding at an effective average price of $2.93/lb and settling across October 2020 to January 2021. As at December 31, 2019, Hudbay had 66.1 million pounds of net copper swaps outstanding at an effective average price of $2.67/lb and settling across January to April 2020. The aggregate fair value of the transactions at September 30, 2020 was a liability of $5,675 (December 31, 2019 was a liability position of $8,362).

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, 2020, Hudbay held contracts for forward zinc purchased of 7.7 million pounds (December 31, 2019 - 12.7 million pounds) that related to forward customer sales of zinc. Prices range from $0.87/lb to $1.14/lb (December 31, 2019 - $1.00/lb to $1.15/lb) and settlement dates extend to January 2021. The aggregate fair value of the transactions at September 30, 2020 was a net asset position of $785 (December 31, 2019 - a net liability position of $221).

(c) Embedded derivatives

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.

Copper pounds<br>(in thousands) 64,104 72,977 2.98
Gold oz 11,664 16,152 1,519
Silver oz 85,782 124,371 16.94

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, 2020, was an asset position of $4,889 (December 31, 2019 - an asset position of $10,165).

Prepayment option embedded derivative

The senior unsecured notes (note 14) contain prepayment options, which represent embedded derivatives that require bifurcation from the host contract. The prepayment options are measured at fair value, with changes in the fair value being recognized as change in fair value of financial instruments (note 5f). The fair value of the embedded derivative at September 30, 2020 was an asset of $9,456 (December 31, 2019 - an asset of $2,585).

Pampacancha delivery obligation-embedded derivative

Hudbay has recognized an obligation to deliver additional precious metal credits to Wheaton as a result of the Pampacancha deposit not being mined until after 2020 (note 12). The fair value of the embedded derivative at September 30, 2020 was a liability of $2,982 (December 31, 2019 - a liability of $9,074).

(d)  Other financial liabilities

Gold prepayment liability

The gold prepayment liability (note 12) requires settlement by physical delivery of gold ounces or equivalent gold credits. The fair value of the embedded derivative at September 30, 2020 was a liability of $132,017 (December 31, 2019 - nil).

(b) Non-cash transactions:

During the nine months ended September 30, 2020 and 2019, Hudbay entered into the following non-cash investing and financing activities which are not reflected in the consolidated statements of cash flows:

  • Remeasurement of Hudbay's decommissioning and restoration liabilities for the nine months ended September 30, 2020 led to a net increase in related property, plant and equipment assets of $50,807 (nine months ended September 30, 2019 - increase of $42,849) related to lower discount rates associated with remeasurement of the liabilities.

  • Property, plant and equipment included $17,420 (nine months ended September 30, 2019 - $19,751) of capital additions related to the recognition of ROU assets.

  • Immediately prior to purchasing United Copper & Moly LLC's ("UCM") remaining interest in the Rosemont project, Hudbay agreed to release UCM from repayment obligations under a Rosemont project loan in exchange for an increase in equity in Rosemont. As a result, the loan receivable balance of $25,978 was written off. Hudbay recognized the loss on write-off of the loan receivable in the income statement (refer to Note 5d). In addition, in order to recognize previously unfunded contributions to the Rosemont Project due from UCM, Hudbay recognized an increase to other capital reserves, a component of shareholder's equity.

OUR BUSINESS

We are a diversified mining company primarily producing copper concentrate (containing copper, gold, and silver) and zinc metal. Directly and through our subsidiaries, we own 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). Our growth strategy is focused on the exploration, development, operation and optimization of properties we already control, as well as other mineral assets we may acquire that fit our strategic criteria. Our vision is to be a responsible, top-tier operator of long-life, low-cost mines in the Americas. We are governed by the Canada Business Corporations Act and our shares are listed under the symbol "HBM" on the Toronto Stock Exchange, New York Stock Exchange and Bolsa de Valores de Lima.

SUMMARY

Third Quarter Operating and Financial Results

  • Delivered a solid operating quarter with steady production and cost performance from the Manitoba and Peru operations, including an increase in copper production over the first two quarters of 2020 and strong gold production driven by increased gold grades at Lalor.

  • Third quarter net loss was $24.0 million or $0.09 per share. Third quarter adjusted net loss^1^ per share was $0.10 and adjusted EBITDA^1^ was $96.1 million.

  • Operating cash flow before change in non-cash working capital increased to $84.4 million in the third quarter of 2020, from $71.2 million in the same quarter of 2019, due to higher realized copper and precious metals prices and higher gold sales volumes, partially offset by lower sales volumes of copper and zinc.

  • Cash and cash equivalents increased during the third quarter to $449.0 million as at September 30, 2020 as a result of the receipt of $191.8 million, net of transaction costs, from the refinancing of our 2023 notes and cash generated from operations, partially offset by capital investments in the New Britannia refurbishment project and our Peru business.

On Track to Achieve Annual Guidance

  • Owing to the performance from the Manitoba operations during the first three quarters of 2020, and the steady operations at Constancia since our eight-week suspension earlier this year, we continue to expect to meet all production, consolidated sustaining capital expenditures and unit cost guidance for 2020, despite ongoing COVID-19 operating challenges.

  • Fourth quarter 2020 production and sales volumes in Manitoba will be impacted by the production interruption at the 777 mine. With the implementation of production mitigation plans, we continue to expect to achieve full year guidance for Manitoba.

Executing on Growth Initiatives

  • The New Britannia gold mill refurbishment project is ahead of schedule and within budget, with detailed engineering approximately 99% complete and construction activities approximately 45% complete. Commissioning of the gold plant is expected in mid-2021, three months earlier than originally planned.

  • Early mining of the gold zone at Lalor is well-underway with underground development in the gold rich lenses advancing ahead of schedule in preparation for the mid-2021 ramp-up of New Britannia. The New Britannia gold mill is expected to increase average annual gold production from Lalor to over 150,000 ounces commencing in 2022.

  • Successfully advanced individual land-user agreements at Pampacancha with 79% of the land turned over to Hudbay as of September 30, 2020 (as compared to approximately 33% as of June 30, 2020).

  • Constancia North follow-up drilling continues to intersect porphyry and skarn mineralization north of the Constancia pit, including one intersection of 78.6 metres grading 1.39% copper, 305 grams per tonne molybdenum, 0.43 grams per tonne gold and 16.0 grams per tonne silver.

  • Completed offering of $600.0 million of 6.125% senior notes due 2029 and redeemed all of our outstanding $400.0 million of 7.250% senior notes due 2023.

Summary of Third Quarter Results

Cash generated from operating activities in the third quarter of 2020 increased to $77.9 million compared to $43.5 million in the same quarter of 2019. Operating cash flow before change in non-cash working capital was $84.4 million during the third quarter of 2020, reflecting an increase of $13.2 million compared to the same period of 2019. The increase in operating cash flow is primarily the result of higher realized copper and precious metals prices and higher gold sales volume, partially offset by lower sales volumes of copper and zinc.

Copper-equivalent production in the third quarter of 2020 decreased by 18% compared to the same period in 2019 primarily as a result of lower copper grades at Constancia, in line with the mine plan, and lower ore production at Constancia due to a scheduled plant maintenance shutdown. However, copper-equivalent production in Manitoba increased by 3% in the third quarter over the same quarter in 2019 primarily due to a 14% increase in gold production from increased gold head grades and sustained throughput improvements at the Stall mill.

Net loss and loss per share in the third quarter of 2020 were $24.0 million and $0.09, respectively, compared to a net loss and loss per share of $274.8 million and $1.05, respectively, in the third quarter of 2019. The prior period loss was mainly caused by an after-tax impairment charge of $242.1 million recorded in our investment in the Rosemont project. During the third quarter of 2020, we recorded a non-cash adjustment on our streaming revenues due to an amendment to the 777 mine plan leading to fewer inferred resources expected to be mined than originally planned as the mine nears its expected closure in 2022. The increased deferred revenue drawdown rate, which is recalculated back to the inception of the stream, resulted in a positive pre-tax non-cash earnings impact of approximately $14.1 million. This was partially offset by $7.3 million in costs primarily relating to the call premium paid to redeem all of our outstanding $400.0 million of 7.25% senior unsecured notes due 2023 (the "Redeemed Notes") and a $3.8 million write-down of unamortized transaction costs related to the Redeemed Notes and our revolving credit facilities, which  were restructured during the quarter.

Adjusted net loss^1^ and adjusted EBITDA^1^ in the third quarter of 2020 were $25.4 million, or $0.10 per share, and $96.1 million, respectively. This compares to an adjusted net loss and adjusted EBITDA of $23.3 million, or $0.09 per share, and $76.2 million, respectively, in the same period of 2019. The increase in adjusted EBITDA in the third quarter of 2020 was primarily due to higher realized copper and precious metals prices and higher gold sales volume, partially offset by lower sales volumes of copper and zinc.

In the third quarter of 2020, consolidated cash cost per pound of copper produced, net of by-product credits^1^, was $0.65, compared to $0.71 in the same period last year. The overall decrease in this measure was a result of increased by-product credit revenues mainly driven by a significant increase in Manitoba's precious metal revenue compared to the same period in 2019, which was partially offset by a decline in copper production at Constancia due to lower grades and a planned August plant maintenance shutdown. Incorporating sustaining capital, capitalized exploration, royalties, selling, administrative and regional costs, consolidated all-in sustaining cash cost per pound of copper produced, net of by-product credits^1^, in the third quarter of 2020 was $2.25, which increased from $1.69 in the same period last year, primarily as a result of higher sustaining capital expenditures and lower copper production at Constancia as mentioned above.

*Reflects Constancia temporary suspension of operations in April and May.

^1^Adjusted net loss and adjusted net loss per share, adjusted EBITDA, cash cost, all-in sustaining cash cost per pound of copper produced, net of by-product credits, and net debt are non-IFRS financial performance measures with no standardized definition under IFRS.

RECENT DEVELOPMENTS

COVID-19 Business Update

Amidst the COVID-19 pandemic, our business response plan continued to be executed throughout the quarter, as we adapt to this fluid environment. We remain focused on the health and safety of our workforce, their families, and the communities in which we operate. We closely monitor the evolution of the pandemic in each of our regions and are continuously reviewing and adapting our procedures based on the latest local situation. Peru currently ranks in the top fifteen countries worldwide in terms of the total number of infections. Arequipa and Cusco, where 80% of our Constancia workforce resides, continue to see a high COVID-19 case count. The province of Manitoba has seen a recent increase in COVID-19 cases, including a growing number of cases in northern Manitoba.

Each of our business units has developed site-specific measures intended to identify and limit COVID-19 exposure and transmission and maintain a safe environment for our workers and our communities. Site-specific measures include testing of incoming workers prior to their travel to site, pre-screening protocols, quarantine periods for incoming workers, workplace physical distancing protocols, and adjustment of work rotation schedules. These measures continue to evolve as the status of the pandemic changes in each of our operating regions and our measures are adapted to the regional health authorities' latest restrictions and guidelines.

We believe the most important way we can support the communities in which we operate is to manage safe operations, which provide income for local employees, businesses, and communities. While we have had members of our workforce contract COVID-19, to date we have not identified cases of transmission within our workplaces, or transmission between rotational employees and local communities. We believe that our diligence in screening and testing, and workplace protocols has been effective in achieving our objective of being a safe employer and neighbour. In addition to our efforts to maintain safe operations, we have been supporting public health efforts and providing COVID-19 relief funding, supplies and services to our neighbouring communities.

777 Operations Update

Production at the 777 mine was temporarily suspended due to an incident that occurred on October 9th during routine maintenance of the hoist rope and skip. The hoist rope detached from the skip, causing the skip to fall to the bottom of the shaft. All underground personnel were safely evacuated from the mine using the secondary ramp access.

A preliminary video inspection of the mine shaft indicates that damage is limited to the headframe and the bottom of the shaft in the skip compartment. It does not appear that the cage compartments or the ore loading area were damaged, and the structural integrity of the shaft does not appear to have been compromised by the incident. A full inspection of the shaft and skip compartment will require an in-person inspection, which is underway.

Underground mining activity has resumed at 777 with limited production from the mine's ramp access. If it is confirmed there is no further damage beyond what has been identified to date, it is expected that the 777 shaft could resume full production in December at a repair cost that is not expected to exceed $5.0 million.

While fourth quarter production and sales volumes will be impacted, we are implementing production mitigation plans. Based on the preliminary video inspection and mitigation plans, we continue to expect the Manitoba business unit to achieve its full year production and unit cost guidance for 2020.

Lalor Mine and the New Britannia Mill Refurbishment Update

The New Britannia refurbishment project is ahead of schedule and on budget. Overall project progress is approximately 64% complete, which includes the completion of 99% of detailed engineering, 98% of project procurement and 45% of construction. Commissioning of the gold plant is expected in mid-2021, three months earlier than planned. Construction of the new copper flotation building continues to advance as planned and is on track to have the external structure fully enclosed before winter. Construction of the pipeline between the New Britannia and Stall mills also continues as planned.

As previously disclosed, we have identified the potential to produce gold from the New Britannia mill earlier in 2021 than originally expected. The refurbishment activities at the gold plant are ahead of schedule and commissioning of the gold plant is now expected in mid-2021, followed by ramp-up and first production in the third quarter of 2021. Copper flotation building construction activities continue to be on track for completion in August 2021, with commissioning and ramp-up expected during the second half of 2021. While the copper flotation building is being constructed, we plan to install modular flotation cells at the gold plant to optimize copper recoveries as we start the early processing of gold and copper-gold ores. The impact of this early gold production from the New Britannia mill continues to be evaluated and will be reflected in our annual production guidance update in early 2021.

We continue with the early mining of the gold zone at Lalor as part of stope sequencing in preparation for the start of the New Britannia gold mill. Once the New Britannia mill is ramped-up, average annual gold production from Lalor is expected to increase to over 150,000 ounces commencing in 2022 at cash costs and sustaining cash costs, net of by-product credits, of approximately $480 and $655 per ounce, respectively, during the first eight years of the gold plant's operation.

Pampacancha Update

We completed the Pampacancha surface rights agreement with the local community of Chilloroya in February 2020. Since that time, we have made significant progress on completing the Pampacancha individual land-user agreements and as of September 30, 2020, approximately 79% of the land has been vacated and turned over to Hudbay (as compared to approximately one third as of June 30, 2020). During the first nine months of 2020, we accrued approximately $95.9 million in growth spending in Peru relating to obligations under the local community surface rights agreement and the individual land-user agreements. As previously disclosed, our initial growth capital guidance for Peru of $70.0 million did not include the cost of the individual land user agreements due to the ongoing nature of the negotiations and, as indicated by accrued expenditures to date, full year growth capital spending for Peru will exceed that initial guidance once all the land user agreements are concluded. As stated in our second quarter results, the Consulta Previa consultation process has been impacted by the Peruvian government declared state of emergency, and as a result, the company expects a Pampacancha production start date of early 2021.

Constancia Regional Exploration

Constancia North Drilling

We have recently completed a follow-up drill program at Constancia North to continue to test a possible extension of copper porphyry and high-grade skarn mineralization occurring within 300 metres of the northern edge of the current Constancia pit. The drill program was a follow-up to the drill intersections announced on March 30, 2020 and continued to intersect both skarn and porphyry mineralization as shown in the table below. Most of the drill holes intersected mineralization located along a southeast-northwest trending regional fault. The results will be evaluated and integrated into the annual mineral reserve and resource estimate update for Constancia at the end of the first quarter of 2021.

Other Regional Exploration

Our patient and consistent approach to community negotiations has proven successful, demonstrating our strong relationships with the neighbouring communities near Constancia and positioning us well to gain access to other regional growth targets in Peru. After reaching an exploration agreement with the Quehuincha community in early 2019 and subsequently completing the Consulta Previa process, we have commenced site preparation work and expect to start our drill program on the Quehuincha North high-grade skarn target in November.

Rosemont Update

The appeal of the unprecedented Rosemont court decision continues to advance. After Hudbay and the U.S. government filed their respective initial briefs in June 2020 with the U.S. Court of Appeals for the Ninth Circuit in relation to the U.S. District Court for the District of Arizona's decision in July 2019, the plaintiffs filed their briefs in September. Hudbay and the U.S. government expect to file their final briefs in November. A final decision in the appeal process is expected in late 2021.

In October 2020, Hudbay commenced a drilling program on its wholly owned private land located in a historic mining district, called Helvetia, near its Rosemont project in Arizona. The focus of the program is two-fold: to complete condemnation drilling in the areas planned for power and water lines for Rosemont, and to test the Helvetia copper district for future exploration potential. We will provide further updates as appropriate.

Senior Unsecured Notes Refinancing

On September 23, 2020, we completed the offering of $600.0 million aggregate principal amount of 6.125% senior notes due April 2029 (the "New Notes"). The New Notes are governed by an indenture, dated as of September 23, 2020, among the Company, the subsidiaries of the Company party thereto as guarantors and U.S. Bank National Association, as trustee.

The proceeds from this offering were primarily used to redeem all $400.0 million of our outstanding 7.250% Redeemed Notes, including the payment of accrued and unpaid interest, a call premium of $7.3 million, and transaction costs associated with the New Notes.

The Constancia team has demonstrated strong operating performance in an environment of strict COVID-19 measures and controls. We work collaboratively with the health authorities to ensure our workforce and partners adhere to our COVID-19 protocols while continuing to operate safely and efficiently.

Ore milled at our Constancia mine during the third quarter of 2020 was 9% lower compared to the same period in 2019 due to a deferred plant maintenance shutdown in August which typically occurs in the second and fourth quarters, as previously disclosed, as well as lower throughput caused by increased ore hardness. Milled gold, silver and copper grades in the third quarter were approximately 25%, 29% and 25% lower, respectively, than the same period in 2019 in line with the mine plan. Copper recoveries in the third quarter of 2020 decreased by 3% compared to the same period in 2019 due to the decrease in milled grade and higher contaminants in the current mining phase of the pit.

Combined mine, mill and G&A unit operating costs in the third quarter of 2020 were 14% higher than the same period in 2019, primarily due to fewer tonnes of ore milled as a result of the plant maintenance in August, which also led to increased operating costs. Unit operating costs in the quarter were within the guidance range for 2020.

Year-to-date combined unit operating costs were generally in line with the same period in 2019, as lower production caused by an eight-week suspension of Constancia mine operations was offset by a corresponding decrease in mine, mill and general and administration costs. We expect cost guidance to be met for the full year 2020.

In the third quarter of 2020, production of copper, gold and silver were 33%, 40%, and 37% lower, respectively, than the same period in 2019 due to lower grades in line with the mine plan and reduced production caused by the August plant maintenance shutdown. Year-to-date 2020 production of copper, gold and silver were 41%, 41%, and 39% lower, respectively, compared to the same period of 2019, due to the same reasons as the third quarter variances as well as the suspension of Constancia operations in the second quarter.

Molybdenum production in the third quarter of 2020 was higher than the same period in 2019 due to higher recovery and slightly higher grade. Year-to-date molybdenum production is in line with the same period in 2019.

We expect production of all metals and unit operating costs at Constancia to be in line with the revised full year guidance for 2020 that was released with our second quarter results.

Cash cost per pound of copper produced, net of by-product credits, for the three and nine months ended September 30, 2020 were $1.54 and $1.45, respectively. Cash cost increased 45% and 32%, respectively, compared to the same periods in 2019. The overall increase is primarily due to lower copper production caused by lower grades and increasing ore hardness as we progress through the mine plan and lower by-product credits.

Sustaining cash cost per pound of copper produced, net of by-product credits increased by 50% compared to the third quarter of 2019, mainly due to the same factors noted above, affecting cash costs as well as accelerated sustaining capital spending following a full ramp up of operations to normal levels in early July 2020 at Constancia. Sustaining cash cost increased 39% on a year-to-date basis, primarily due to the same factors noted above, offset by lower sustaining capital spending due to a curtailment of activity during the eight-week shutdown at Constancia in the second quarter of 2020.

The Manitoba business unit had solid operating performance across the mines, mills and zinc plant during the third quarter. In the face of the ongoing COVID-19 pandemic, we have maintained the controls that were developed in the early part of the year and our health and safety committees have continued to work collaboratively with local health units with a focus on keeping our employees and communities safe.

Operational performance during the third quarter at both Lalor and 777 was strong, with ore production generally in line with the same period in 2019 and grades at both mines remaining in line with the mine plan. At Lalor, we completed a two-week planned maintenance program, on schedule and achieved a third quarter production rate averaging 4,600 tonnes per day outside of the maintenance period. The 777 mine maintained consistent and stable performance during the third quarter as it approaches its planned closure in 2022.

Operational readiness activities in support of the early start-up of New Britannia are on track, including ensuring that a sufficient and consistent volume of gold ore will be available. Underground development at Lalor in gold-rich lenses 25 and 27 is advancing ahead of schedule in preparation for the mid-2021 start-up of New Britannia, which is three months earlier than previously planned. Mining of the first stope in lens 27 was completed in September and the trend of increased precious metal production from Lalor is expected to continue.

Total unit operating costs for the mines during the third quarter of 2020 decreased by 3% compared to the same period in 2019 mainly due to lower unit costs at Lalor. Year-to-date total unit operating costs for the mines decreased by 6% for the same reason.

At the Stall concentrator, ore processed during the third quarter of 2020 was 5% higher than the same period in 2019, despite a planned one-week outage on one of the grinding lines for capital upgrades. Year-to-date ore processed at Stall increased by 6% as a result of several continuous improvement initiatives and higher ore availability from the Lalor mine. Although lower than the first half of 2020, the trend of improved gold recoveries has continued compared to the same periods in 2019 due to improved ore characteristics and numerous operational improvement projects implemented at the Stall mill.

Ore processed in the Flin Flon concentrator in the third quarter of 2020 decreased by 3% compared to the same period in 2019 due to less Lalor ore required to be processed in Flin Flon as a result of higher throughput at the Stall mill. Metal recoveries at the Flin Flon concentrator during the third quarter of 2020 decreased slightly compared with the same period in 2019, which was in line with metallurgical models. Year-to-date ore processed at the Flin Flon mill remained largely unchanged from the same period in 2019.

Unit operating costs at Stall decreased by 8% in the third quarter of 2020 compared to the same period in 2019, due to increased throughput, whereas unit operating costs at Flin Flon were 4% higher over the same period because of reduced ore throughput. Manitoba combined mine, mill and G&A unit operating costs in the third quarter of 2020 decreased by 3% compared to the same period in 2019. Year-to-date combined mine, mill and G&A unit operating costs were 6% lower as the mines and mills delivered efficient results. Manitoba combined unit costs are expected to be within the guidance range for the full year 2020.

In the third quarter of 2020, gold, silver and zinc production was 14%, 1%, and 7% higher, compared to the same period in 2019, **** due to higher head grades and higher gold and zinc recoveries. Copper production declined by 14% in the third quarter of 2020 due to lower head grades. Year-to-date, gold, silver and zinc production increased by 24%, 12% and 4%, respectively, **** due to higher throughput and higher gold and silver head grades. Year-to-date copper production decreased by 6% as head grades and recoveries decreased compared to the same period in 2019.

Fourth quarter 2020 production and sales volumes in Manitoba will be impacted by the production interruption at the 777 mine. With the implementation of production mitigation plans, we continue to expect to achieve full year guidance for Manitoba.

Cash cost per pound of copper produced, net of by-product credits, in the third quarter of 2020 was negative $3.41. These costs were lower compared to the same period in 2019, primarily as a result of higher by-product credits and lower mining costs, partially offset by lower copper production. Cash cost per pound of copper produced, net of by-product credits, for the first nine months of 2020 were lower compared to the same period, primarily due to the same reasons.

Sustaining cash cost per pound of copper produced, net of by-product credits, in the third quarter of 2020 was $0.83. These costs were lower compared to the same period in 2019, primarily due to the reasons listed above slightly offset by increased sustaining capital expenditures. Sustaining cash cost per pound of copper produced, net of by-product credits, for the first nine months of 2020 were lower compared to the same period in 2019, primarily due to the same reasons.

Cash cost and sustaining cash cost per pound of zinc produced, net of by-product credits, in the third quarter of 2020 were lower than the same period last year as a result of significantly higher by-product credits, lower mining costs and higher zinc production, partially offset by higher sustaining capital expenditures.

Cash cost and sustaining cash cost per pound of zinc produced, net of by-product credits, were lower in the first nine months of 2020 compared to the same period in 2019 due to increased zinc production, significantly higher by-product credits and lower mining costs, partially offset by higher sustaining capital expenditures.

FINANCIAL REVIEW

Financial Results

In the third quarter of 2020, we recorded a net loss of $24.0 million compared to a loss of $274.8 million for the same period in 2019, representing a reduction in loss of $250.8 million. Year-to date in 2020, we recorded a loss of $152.0 million compared to a loss of $342.4 million in the same period in 2019, reducing net loss by $190.4 million.

Revenue

Revenue for the third quarter of 2020 was $316.1 million, $24.8 million or 9% higher than the same period in 2019, primarily as a result of higher realized copper and precious metals prices and higher gold sales volume as well as a variable consideration adjustment on our Manitoba stream revenue and lower comparative treatment and refining charges. This was partially offset by lower sales volumes of copper and zinc.

Year-to-date revenue in 2020 was $770.1 million, $142.8 million or 16% lower than the same period in 2019, primarily as a result of significantly lower copper sales volumes in Peru as a result of an eight-week suspension of Constancia operations in the second quarter and lower copper grades as well as lower realized base metal prices and silver sales volumes. This was partially offset by higher realized gold prices, a variable consideration adjustment on stream revenue as well as lower comparative treatment and refining charges.

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 third quarter in 2020 and 2019, respectively, are summarized below:

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 2020 was $276.8 million, reflecting an increase of $16.5 million from the third quarter of 2019. Cost of sales related to Peru increased in the third quarter of 2020, compared to the same period of 2019, by $15.0 million. The increase is primarily the result of changes in product inventory, increased depreciation charges and increased milling costs. In Manitoba, cost of sales increased by $1.5 million, compared to the third quarter of 2019, primarily as a result of higher depreciation costs from an increase to our decommissioning and restoration assets offset by changes in product inventory.

Year-to-date, cost of sales was $765.5 million, which was $21.6 million less than the same period in 2019. The decrease is principally related to lower production costs from an eight-week suspension of Constancia operations in the second quarter of 2020. During the shut-down, an adjustment to cost of sales was recorded for $31.9 million of fixed overhead costs (cash: $15.8 million, non-cash: $16.1 million included in depreciation) that would ordinarily have been capitalized to inventories and property, plant, and equipment. In Manitoba, depreciation increased by $31.4 million as a result of increases to our decommissioning and restoration obligation assets that were recorded in the fourth quarter of 2019 and are being depreciated straight-line through to the end of the mine life in 2022.

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 2020, other significant variances in expenses from operations, compared to the same period in 2019, include the following:

  • Selling and administrative expense **** increased by $5.7 million compared to the same period in 2019. This increase was mainly due to higher stock-based compensation charges as a result of the relative impact of the revaluation of previously issued share units to higher share prices, partially offset by a general reduction in consulting and travel costs.

  • Exploration and evaluation expenses decreased by $4.9 million compared to the third quarter of 2019, in line with the reduced 2020 exploration budget compared to 2019.

  • Impairment losses decreased by $322.2 million as a result of an impairment charge recorded in the third quarter of 2019 in our investment in the Rosemont project.

For 2020 year-to-date, other significant variances in expenses from operations, compared to 2019, include the following:

- Selling and administrative expense **** decreased by $3.8 million compared to the same period in 2019. This decrease was mainly due to a general reduction in consulting, legal and travel costs, partially offset by higher stock-based compensation charges as a result of the relative impact of revaluation of previously issued share units to higher share prices.

  • Other expenses **** decreased by $35.6 million due to the write down of a joint venture receivable from prior year of $26.0 million as well as the recognition of a delivery obligation related to the Pampacancha deposit from prior year of $7.5 million, neither of which reoccurred in the current year.

  • Exploration and evaluation expenses decreased by $10.3 million in line with the reduced 2020 exploration budget compared to 2019.

  • Impairment losses decreased by $322.2 million as a result of an impairment charge recorded in the third quarter of 2019 in our investment in the Rosemont project.

Compared to the three months ended September 30, 2019, net finance expense increased by $7.1 million.  Accrued finance costs increased by $11.0 million mostly due to a $7.3 million early redemption premium paid to holders of our Redeemed Notes. Non-cash finance costs decreased by $3.9 million primarily as a result of a net increase of $6.3 million in the market value of our investments measured through profit or loss consisting of securities in Canadian metals and mining companies as well as a $4.7 million variable consideration adjustment reducing the accretion expense on our stream arrangements. Offsetting these gains was a $3.8 million write-down of unamortized transaction costs and a $3.3 million increase in net interest charges as we no longer capitalize interest costs on the Rosemont project effective October 1, 2019, due to its delay in development.

On a year-to-date basis, net finance expense **** increased by $20.2 million compared to the same period in 2019 mainly for the reasons as described above and due to $16.7 million in losses from the non-cash revaluation of our gold prepayment liability measured through profit or loss.

Tax Recovery

For the three and nine months ended September 30, 2020, tax recovery decreased by $73.6 million and $40.1 million, respectively, compared to the same period in 2019. The following table provides further details:

Income Tax Recovery

Applying the estimated Canadian statutory income tax rate of 27.0% to our loss before taxes of $180.0 million for the year-to-date period in 2020 would have resulted in a tax recovery of approximately $48.6 million; however, we recorded an income tax recovery of $27.8 million. The significant items causing our effective income tax rate to be different than the 27.0% estimated Canadian statutory income tax rate include:

  • Deferred tax expense of approximately $5.5 million as certain non-monetary assets are recognized at historical cost while the tax bases of the assets change as the exchange rates fluctuates, which creates taxable temporary differences.

  • Certain deductible temporary differences mostly with respect to Peru, 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 Peruvian operations.  This has resulted in deferred tax expense of $7.9 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 $4.5 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 27%, resulting in a deferred tax expense of $4.3 million.

  • Certain foreign exchange gains and other items are not taxable for local income tax purposes and therefore result in a deferred tax recovery of approximately $1.5 million.

Mining Tax Recovery

Applying the estimated Manitoba mining tax rate of 10.0% to our loss before taxes of $180.0 million for the year-to-date period in 2020 would have resulted in a tax recovery of approximately $18.0 million; however, we recorded a mining tax recovery of $0.2 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, 2020, at the tax rate we expect to apply when temporary differences reverse.

LIQUIDITY AND CAPITAL RESOURCES

Senior Unsecured Notes Refinancing

On September 23, 2020, we completed the offering of $600.0 million aggregate principal amount of 6.125% senior notes due April 2029. The New Notes are governed by an indenture, dated as of September 23, 2020, among the Company, the subsidiaries of the Company party thereto as guarantors and U.S. Bank National Association, as trustee.

The proceeds from this offering were primarily used to redeem all $400.0 million of our outstanding 7.250% Redeemed Notes, including the payment of accrued and unpaid interest and a call premium of $7.3 million, and to pay transaction costs associated with the New Notes.

Senior Secured Revolving Credit Facilities

On August 31, 2020, we completed an amendment to our senior secured revolving credit facilities (the "Credit Facilities"). As a result of the amendment, the total available borrowings under the Credit Facilities has decreased to $400.0 million from $550.0 million to reflect our anticipated business requirements until June 2022 when the Credit Facilities mature. We also revised various financial covenants as follows:

  • Maintaining net debt to EBITDA ratio of less than:

• 5.25:1 from September 30, 2020 to December 31, 2021; and,

• 3.50:1 from January 1, 2022 to maturity.

  • Maintaining an interest coverage ratio of greater than:

• 2.50:1 from September 30, 2020 to December 31, 2021; and,

• 3.00:1 from January 1, 2022 to maturity.

  • Maintaining a minimum liquidity of greater than $50 million to December 31, 2021.

The EBITDA calculation for the purposes of the covenants may differ from the non-IFRS measure of adjusted EBITDA shown in this MD&A. As at September 30, 2020, our liquidity includes $449.0 million in cash and cash equivalents as well as undrawn availability of $291.4 million under our Credit Facilities. As at September 30, 2020, we are in compliance with our covenants under the Credit Facilities and have drawn $108.6 million in letters of credit under the Credit Facilities.

As at September 30, 2020, the Arizona business unit had $8.6 million in surety bonds and the Peru business unit had $20.0 million in surety bonds issued to support future reclamation and closure obligations. The Peru business unit also had $45.0 million in letters of credit issued with various Peruvian financial institutions. No cash collateral is required to be posted under these letters of credit or surety bonds.

Financial Condition

Financial Condition as at September 30, 2020 compared to December 31, 2019

Cash and cash equivalents increased by $52.9 million during the first nine months of the year to $449.0 million as at September 30, 2020. This increase was mainly the result of cash flow from operating activities of $118.4 million, $115.0 million of proceeds from the gold prepay transaction and approximately $191.8 million in net proceeds raised from our New Notes offering. Offsetting these cash inflows was $243.3 million of capital investments primarily at our Peru and Manitoba operations, interest payments of $81.5 million, other leasing and financing costs of $39.0 million, a $7.3 million premium paid to redeem our 2023 Notes and paid dividends of $3.8 million. We hold the majority of our cash and cash equivalents in low-risk, liquid investments with major Canadian and Peruvian financial institutions.

Working capital increased by $132.2 million to $403.4 million from December 31, 2019 to September 30, 2020, primarily due to the cash and cash equivalent increase of $52.9 million, a decrease in our trade and other payables  of $35.2 million arising mainly from timing of interest payments on our senior unsecured notes, an increase of $23.0 in accounts receivable due to timing of cash receipts, a reduction of the current portion of deferred revenue by $13.6 million based on changes in expected future stream deliveries, and a decrease in other current financial liabilities of $9.5 million mainly as a result of a reduction in the fair value of certain provisionally priced sales receivables and other embedded derivatives.

Cash Flows

The following table summarizes our cash flows for the three and nine months ended September 30, 2020 and September 30, 2019:

(in $ thousands) Three months ended Nine months ended

Increase (decrease) in cash and cash equivalents 57,878 (91,089) 52,868 (117,059)

Cash Flow from Operating Activities

Cash generated from operating activities was $77.9 million during the third quarter of 2020, an increase of $34.5 million compared with the same period in 2019. Operating cash flow before change in non-cash working capital was $84.4 million during the third quarter of 2020, reflecting an increase of $13.2 million compared to the third quarter of 2019. The increase in operating cash flow is primarily the result of higher realized copper and precious metals prices and higher gold sales volume. This was partially offset by lower sales volumes of copper and zinc compared to the third quarter of 2019.

Year-to-date cash generated from operating activities was $118.4 million, representing a decrease of $93.8 million compared to the same period in 2019. Operating cash flow before change in non-cash working capital was $155.8 million during the first nine months of 2020, compared to $238.1 million during the same period in 2019. The year-to-date decrease in operating cash flow is due to significantly lower copper sales volumes in Peru as a result of an eight-week suspension of Constancia operations in the second quarter and lower copper grades as well as lower realized base metal prices and silver sales volumes. This was partially offset by higher realized gold prices.

Cash Flow from Investing and Financing Activities

During the third quarter of 2020, we used $19.3 million in investing and financing activities, primarily driven by $144.5 million of capital expenditures, interest payments of $44.1 million, capitalized lease payments of $9.4 million and other financing payments of $11.5 million. Offsetting these payments was net proceeds of $191.8 million from our New Notes offering, net of transaction costs.

Year-to-date, we used $66.2 million in investing and financing activities, composed primarily of $243.3 million of capital investments, interest payments of $81.5 million, capitalized lease payments of $26.6 million and other financing payments of $19.6 million, partially offset by net proceeds of $191.8 million from our New Notes offering, and $115.0 million of proceeds from the gold prepay transaction.

Capital Expenditures

3 Hudbay's initial growth capital guidance for Peru of 70 million did not include the cost of the individual land user agreements due to the ongoing nature of the negotiations and, as indicated by accrued expenditures to date, full year growth capital spending for Peru will exceed that initial guidance once all land user agreements are concluded.
4 Other capitalized costs include decommissioning and restoration adjustments.

All values are in US Dollars.

Sustaining capital expenditures in Manitoba for the three and nine months ended September 30, 2020 were $23.3 million and $74.3 million respectively, representing a decrease of $21.2 million and a decrease of $21.4 million compared to the same period in 2019. The decrease is due to a reduction in capital development at the 777 mine as it nears the end of its mine life in 2022.

Sustaining capital expenditures in Peru for the three and nine months ended September 30, 2020 were $35.0 million and $54.2 million respectively, representing increases of $10.0 million and  $0.7 million, respectively, from the same period in 2019. The increase in Peru sustaining capital expenditures compared to the same period last year was mainly due to the shifting of costs from the second quarter to the third quarter due to a temporary suspension of operations at Constancia earlier this year. Increased expenditures in the current quarter primarily relate to additions to in mine and plant equipment capitalized leases.

We expect consolidated sustaining capital expenditures in 2020 to be in line with full year guidance.

Year-to-date Peru growth capital of $95.9 million includes the recognition of future spending obligations arising from the execution of the surface rights agreement with the local community and agreements related to current uses of the land by certain community members. During the first nine months of 2020, we made payments of approximately $84.3 million, representing the majority of expenditures under these agreements. As previously disclosed, the company's initial growth capital guidance for Peru of $70.0 million did not include the cost of the individual land user agreements due to the ongoing nature of the negotiations and, as indicated by accrued expenditures to date, full year growth capital spending for Peru will exceed that initial guidance once all land user agreements are concluded.

Year-to-date Manitoba growth capital of $30.4 million includes spending for the New Britannia refurbishment project which includes construction of the new copper flotation building and construction of a pipeline between the New Britannia and Stall mills. The project is currently approximately 64% complete and is tracking ahead of schedule while remaining on budget. Full year growth capital spending for Manitoba is expected to be lower than guidance as some anticipated 2020 capital spend is forecast to be incurred in 2021.

Other capitalized costs for the three and nine months ended September 30, 2020 were negative $6.5 million and $53.3 million, respectively, and relate primarily to the remeasurement of previously recognized decommissioning and restoration liabilities at our Peru and Manitoba operations.

Capital Commitments

As at September 30, 2020, we had outstanding capital commitments in Canada of approximately $42.9 million of which $37.7 million can be terminated, approximately $34.7 million in Peru primarily related to exploration option agreements, all of which can be terminated, and approximately $179.8 million in Arizona, primarily related to our Rosemont project, of which approximately $89.2 million can be terminated.

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

During the third quarter of 2020, our business was able to adapt to the global impact of the evolving COVID-19 pandemic. We benefited from increasing commodity prices and consistent, uninterrupted operations in Manitoba and Peru while adhering to established health and safety protocols. During the quarter, we redeemed our 2023 senior unsecured notes and issued new senior unsecured notes maturing in 2029 raising incremental gross proceeds of $200 million. Our third quarter results were impacted by a $7.3 million premium paid to redeem the 2023 notes as well as a $3.8 million write-down of unamortized transaction costs offset by an after-tax non-cash adjustment of $9.0 million on our streaming revenues.

Due to the temporary suspension of operations at Constancia throughout April and into mid-May 2020, we had lower second quarter production and sales volumes and higher production costs by $25.6 million as a result of the immediate recognition of fixed overhead production costs incurred during the suspension. The first quarter results were less impacted by the shutdown and reflected $6.3 million of shutdown-related production costs as well as an inventory write-down of $10.4 million triggered by lower copper prices.

In 2019, the lower realized prices for copper and zinc, combined with a trend towards lower copper grades in the Constancia mine plan and the closure of the Reed copper mine in August 2018 resulted in lower revenues and gross margin, despite the lower Constancia grades being partially offset by higher mill throughput and recoveries. Earnings in 2019 were also impacted by an after-tax impairment charge of $242.1 million in the third quarter of 2019, as well as a UCM receivable write down of $26.0 million in the second quarter of 2019. In the first quarter of 2019, pre-tax revenue and finance expenses were negatively impacted by a $22.3 million charge due to a deferred revenue adjustment arising from higher net mineral reserves and resources.

NON-IFRS FINANCIAL PERFORMANCE MEASURES

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

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

In the first half of 2020, a government-imposed shutdown of non-essential businesses led to a temporary suspension of our Constancia mining operations. As such, 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 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 changes in estimates of asset retirement obligations at closed sites, 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, 2020 and 2019.

After adjusting reported net loss for those items not considered representative of the Company's core business or indicative of future operations, the Company had an adjusted net loss in the third quarter 2020 of $25.4 million or $0.10 loss per share.

Adjusted EBITDA

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

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.

Effective September 30, 2020 and for all comparably disclosed periods, we have included the period's deferred revenue amortization as a by-product credit to reflect the net cost of producing and selling the period's precious metals under our streaming arrangements as we believe doing so allows management and our investors to better evaluate the operating performance of the underlying operations. The variable consideration adjustment required under IFRS 15 related to prior periods is not included as a by-product credit in the current period and hence is disclosed as an adjustment in the non-IFRS cash cost measure reconciliation.

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, 2020 and 2019. 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.

Effective September 30, 2020 and for all comparably disclosed periods, we have included the period's deferred revenue amortization as a by-product credit to reflect the net cost of producing and selling the period's precious metals under our streaming arrangements as we believe doing so allows management and our investors to better evaluate the operating performance of the underlying operations. The variable consideration adjustment required under IFRS 15 related to prior periods is not included as a by-product credit in the current period and hence is disclosed as an adjustment in the non-IFRS cash cost measure reconciliation.

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, 2020 and 2019. 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, 2020 and 2019.

ACCOUNTING CHANGES AND CRITICAL ESTIMATES

New standards and interpretations adopted

For information on new standards and interpretations adopted, refer to note 4 of our September 30, 2020 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, 2020 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, 2020 that materially affected or are reasonably likely to materially affect our ICFR.

Hudbay Announces Third Quarter 2020 Results

Toronto, Ontario, November 3, 2020 - Hudbay Minerals Inc. ("Hudbay" or the "company") (TSX, NYSE:HBM) today released its third quarter 2020 financial results. All amounts are in U.S. dollars, unless otherwise noted.

Third Quarter Operating and Financial Results

  • Delivered a solid operating quarter with steady production and cost performance from the Manitoba and Peru operations, including an increase in copper production over the first two quarters of 2020 and strong gold production driven by increased gold grades at Lalor.
  • Third quarter net loss was $24.0 million or $0.09 per share. Third quarter adjusted net loss^[i]^ per share was $0.10 and adjusted EBITDA^i^ was $96.1 million.
  • Operating cash flow before change in non-cash working capital increased to $84.4 million in the third quarter of 2020, from $29.5 million in the second quarter of 2020, due to higher realized prices and increased sales volumes at Constancia after the successful ramp up to full production.
  • Cash and cash equivalents increased during the third quarter to $449.0 million as at September 30, 2020 as a result of the net proceeds received from the refinancing of the 2023 notes and cash generated from operations, partially offset by capital investments in the New Britannia refurbishment project and the company's Peru business and interest payments.

On Track to Achieve Annual Guidance

  • Owing to the outstanding performance from the Manitoba operations during the first three quarters of 2020, and the steady operations at Constancia since the eight-week suspension earlier this year, Hudbay continues to expect to meet all production, consolidated sustaining capital expenditures and unit cost guidance for 2020, despite ongoing COVID-19 operating challenges.
  • Fourth quarter 2020 production and sales volumes in Manitoba will be impacted by the production interruption at the 777 mine. With the implementation of production mitigation plans, the company continues to expect to achieve full year guidance for Manitoba.

Executing on Growth Initiatives

  • The New Britannia gold mill refurbishment project is ahead of schedule and within budget, with detailed engineering approximately 99% complete and construction activities approximately 45% complete. Commissioning of the gold plant is expected in mid-2021, three months earlier than originally planned.

  • Early mining of the gold zone at Lalor is well-underway with underground development in the gold rich lenses advancing ahead of schedule in preparation for the mid-2021 ramp up of New Britannia. The New Britannia gold mill is expected to increase average annual gold production from Lalor to over 150,000 ounces commencing in 2022.

  • Successfully advanced individual land-user agreements at Pampacancha with 79% of the land turned over to Hudbay as of September 30, 2020 (as compared to approximately 33% as of June 30, 2020).

TSX, NYSE - HBM2020 No. 22
  • Constancia North follow-up drilling continues to intersect porphyry and skarn mineralization north of the Constancia pit, including one intersection of 78.6 metres grading 1.39% copper, 305 grams per tonne molybdenum, 0.43 grams per tonne gold and 16.0 grams per tonne silver.
  • Completed offering of $600.0 million of 6.125% senior notes due 2029 and redeemed all of the outstanding $400.0 million of 7.250% senior notes due 2023.

"We continue to be pleased with the team's ability to maintain strong operating and financial performance while executing on our growth initiatives," said Peter Kukielski, President and Chief Executive Officer. "Our Peru operations have been successfully running at full capacity after having been temporarily suspended in the second quarter due to government-imposed COVID-19 restrictions, and we have maintained positive momentum at Pampacancha. Our Manitoba operations had the best quarterly cost performance in the last two years, demonstrating our focus on continuous improvement initiatives and cost control. The New Britannia project is on budget and ahead of schedule with first gold production expected three months earlier in 2021 than originally planned. The 777 skip incident was an unfortunate event but we are grateful all underground personnel were safely evacuated and we are hopeful the repairs will be completed quickly. We are proud of our team's achievement of several significant milestones while adapting to the ever-changing COVID-19 environment and focus on keeping our workforce and communities safe during this pandemic."

Summary of Third Quarter Results

Consolidated copper production in the third quarter of 2020 was 25,395 tonnes, a 41% increase from the second quarter of 2020, primarily as a result of the successful ramp up at Constancia after the eight-week temporary suspension from mid-March to mid-May. Consolidated gold production decreased by 10% compared to the second quarter of 2020 due to lower production from Manitoba as a result of the planned maintenance at the Lalor mine in the third quarter and the record quarterly gold production achieved in the second quarter in Manitoba. Consolidated zinc production in the third quarter was in line with the second quarter of 2020.

In the third quarter of 2020, consolidated cash cost per pound of copper produced, net of by-product credits^i^, was $0.65, higher than the second quarter of 2020 when cash costs, net of by-product credits, were more heavily impacted by the lower cash costs in Manitoba due to the temporary Peru suspension. Incorporating sustaining capital, capitalized exploration, royalties, selling, administrative and regional costs, consolidated all-in sustaining cash cost per pound of copper produced, net of by-product credits^i^, in the third quarter of 2020 was $2.25, higher than the prior quarter due to the same factors affecting cash costs, and higher sustaining capital expenditures.

Cash generated from operating activities in the third quarter of 2020 increased to $77.9 million compared to $31.4 million in the second quarter of 2020. Operating cash flow before change in non-cash working capital was $84.4 million during the third quarter of 2020, reflecting an increase of $54.9 million compared to the second quarter of 2020. The increase in operating cash flow is primarily the result of increased sales volumes at Constancia due to the ramp up to full production after the temporary suspension, lower operating costs in Manitoba and improved commodity prices.

TSX, NYSE - HBM2020 No. 22

Net loss and loss per share in the third quarter of 2020 were $24.0 million and $0.09, respectively, compared to a net loss and loss per share of $51.9 million and $0.20, respectively, in the second quarter of 2020. During the third quarter of 2020, Hudbay recorded a non-cash adjustment on streaming revenues due to an amendment to the 777 mine plan leading to fewer inferred resources expected to be mined than previously planned as the mine nears its expected closure in 2022. The increased deferred revenue drawdown rate, which is recalculated back to the inception of the stream, resulted in a positive pre-tax non-cash earnings impact of approximately $14.1 million. This was partially offset by $7.3 million in costs primarily relating to the call premium paid to redeem all of the outstanding $400.0 million of 7.25% senior unsecured notes due 2023 (the "Redeemed Notes") and a $3.8 million write-down of unamortized transaction costs related to the Redeemed Notes and the company's revolving credit facilities, which were restructured during the quarter.

Adjusted net loss^i^ and adjusted EBITDA^i^ in the third quarter of 2020 were $25.4 million, or $0.10 per share, and $96.1 million, respectively, after adjusting for the call premium paid on the Redeemed Notes, the write-down of unamortized transaction costs related to the Redeemed Notes and amended credit facilities, and the non-cash adjustment on streaming revenues. This compares to an adjusted net loss and adjusted EBITDA of $51.9 million, or $0.15 per share, and $49.1 million, respectively, in the second quarter of 2020. The increase in adjusted EBITDA in the third quarter of 2020 was primarily due to increased sales volumes in Peru after the successful mine ramp up, lower operating costs in Manitoba and higher realized prices, partially offset by lower sales volumes in Manitoba.

The Constancia team has demonstrated strong operating performance in an environment of strict COVID-19 measures and controls. Hudbay works collaboratively with the health authorities to ensure its workforce and partners adhere to the company's COVID-19 protocols while continuing to operate safely and efficiently.

During the quarter, the Constancia mine produced 20,803 tonnes of copper, 8,167 ounces of precious metals and 392 tonnes of molybdenum. Production results were significantly higher than the second quarter of 2020 as a result of the ramp-up to full production after the temporary suspension of operations until mid-May.

TSX, NYSE - HBM2020 No. 22

The ramp-up also resulted in a significant increase in ore milled during the third quarter at Constancia compared to the second quarter of 2020. Compared to the same period in 2019, ore milled was 9% lower due to a deferred plant maintenance shutdown in August, which typically occurs in the second and fourth quarters, as previously disclosed, as well as lower throughput caused by increased ore hardness. Milled copper grades in the third quarter were slightly lower than the second quarter of 2020, in line with the mine plan. Copper recoveries in the third quarter were higher than the second quarter of 2020 due to the processing of stockpile ore after the mill ramp-up in the second quarter.

Combined mine, mill and G&A unit operating costs^i^ in the third quarter of 2020 were higher than the second quarter of 2020, primarily due to abnormally low operating costs during the second quarter as a result of the processing of stockpile ore after the mill ramp up. Unit operating costs in the quarter were within the guidance range for 2020.

Peru's cash cost per pound of copper produced, net of by-product credits, for the three months ended September 30, 2020 was $1.54, higher than the previous quarter primarily due to higher operating costs, as described above, and lower grades. Peru's sustaining cash cost per pound of copper produced, net of by-product credits, for the three months ended September 30, 2020 also increased compared to the prior quarter primarily due to the same factors affecting cash cost as well as accelerated sustaining capital spending following a full ramp up of operations to normal levels in early July 2020 at Constancia.

Production of all metals and unit operating costs at Constancia are expected to be in line with the revised full year guidance for 2020 that was released with second quarter results.

The Manitoba business unit had solid operating performance across the mines, mills and zinc plant during the third quarter. In the face of the ongoing COVID-19 pandemic, the controls that were developed in the early part of the year have been maintained and the company's health and safety committees have continued to work collaboratively with local health units with a focus on keeping employees and communities safe.

Production during the quarter included 30,570 tonnes of zinc, 4,592 tonnes of copper and 28,657 ounces of precious metals. Production results were slightly lower compared to the previous quarter primarily due to lower head grades and planned maintenance at the Lalor mine during the third quarter.

Operational performance during the third quarter at both Lalor and 777 was strong, with ore production generally in line with the same period in 2019 and grades at both mines remaining in line with the mine plan. At Lalor, a two-week planned maintenance program was completed on schedule, and the company achieved a third quarter production rate averaging 4,600 tonnes per day outside of the maintenance period. The 777 mine maintained consistent and stable performance during the third quarter as it approaches its planned closure in 2022.

Operational readiness activities in support of the early start-up of New Britannia are on track, including ensuring that a sufficient and consistent volume of gold ore will be available. Underground development at Lalor in gold-rich lenses 25 and 27 is advancing ahead of schedule in preparation for the mid-2021 start-up of New Britannia, which is three months earlier than originally planned. Mining of the first stope in lens 27 was completed in September and the trend of increased precious metal production from Lalor is expected to continue.

At the Stall concentrator, ore processed during the third quarter of 2020 was in line with the second quarter, as both periods had planned outages for capital upgrades. Although lower than the first half of 2020, the trend of improved gold recoveries has continued compared to the same periods in 2019 due to improved ore characteristics and numerous operational improvement projects implemented at the Stall mill. At the Flin Flon concentrator, ore processed during the third quarter slightly decreased by 1% compared to the second quarter.

Combined mine, mill and G&A unit operating costs in the third quarter decreased by 7% compared to the second quarter of 2020 primarily due to lower operating costs. Manitoba's combined unit costs are expected to be within the guidance range for the full year 2020.

Manitoba's cash cost per pound of copper produced, net of by-product credits, for the third quarter of 2020 was negative $3.41. These costs were significantly lower compared to the second quarter of 2020, primarily as a result of higher by-product credits and lower mining costs, partially offset by lower copper production. Manitoba's sustaining cash cost per pound of copper produced, net of by-product credits, in the third quarter of 2020 was $0.83, lower than the previous quarter due to the reasons listed above, slightly offset by increased sustaining capital expenditures.

COVID-19 Business Update

Amidst the COVID-19 pandemic, Hudbay's business response plan continued to be executed throughout the quarter, as the company adapts to this fluid environment. The focus remained on the health and safety of Hudbay's workforce and families, and the communities in which the company operates. The evolution of the pandemic has been closely monitored in each of the regions Hudbay operates in and the company is continuously reviewing and adapting procedures based on the latest local situation. Peru currently ranks in the top fifteen countries worldwide in terms of the total number of infections. Arequipa and Cusco, where 80% of Constancia's workforce resides, continue to see a high COVID-19 case count. The province of Manitoba has seen a recent increase in COVID-19 cases, including a growing number of cases in northern Manitoba.

Hudbay's business units have developed site-specific measures intended to identify and limit COVID-19 exposure and transmission and maintain a safe environment for workers and communities. Site-specific measures include testing of incoming workers prior to their travel to site, pre-screening protocols, quarantine periods for incoming workers, workplace physical distancing protocols, and adjustment of work rotation schedules. These measures continue to evolve as the status of the pandemic changes in each of the regions in which the company operates with measures being adapted to the regional health authorities' latest restrictions and guidelines.

Hudbay believes the most important way the company can support the communities in which it operates is to manage safe operations, which provide income for local employees, businesses, and communities. While the company has had members of its workforce contract COVID-19, to date there have been no identified cases of transmission within its workplaces, or transmission between rotational employees and local communities. The company believes that its diligence in screening and testing, and workplace protocols have been effective in achieving the objective of being a safe employer and neighbour. In addition to the company's efforts to maintain safe operations, it has been supporting public health efforts and providing COVID-19 relief funding, supplies and services to neighbouring communities.

777 Operations Update

Production at the 777 mine was temporarily suspended due to an incident that occurred on October 9^th^ during routine maintenance of the hoist rope and skip. The hoist rope detached from the skip, causing the skip to fall to the bottom of the shaft. All underground personnel were safely evacuated from the mine using the secondary ramp access.

A preliminary video inspection of the mine shaft indicates that damage is limited to the headframe and the bottom of the shaft in the skip compartment. It does not appear that the cage compartments or the ore loading area were damaged, and the structural integrity of the shaft does not appear to have been compromised by the incident. A full inspection of the shaft and skip compartment will require an in-person inspection, which is underway.

Underground mining activity has resumed at 777 with limited production from the mine's ramp access. If it is confirmed there is no further damage beyond what has been identified to date, it is expected that the 777 shaft could resume full production in December at a repair cost that is not expected to exceed $5.0 million.

While fourth quarter production and sales volumes will be impacted, the company is implementing production mitigation plans. Based on the preliminary video inspection and mitigation plans, the company continues to expect the Manitoba business unit to achieve its full year production and unit cost guidance for 2020.

Lalor Mine and the New Britannia Mill Refurbishment Update

The New Britannia refurbishment project is ahead of schedule and on budget. Overall project progress is approximately 64% complete, which includes the completion of 99% of detailed engineering, 98% of project procurement and 45% of construction. Commissioning of the gold plant is expected in mid-2021, three months earlier than planned. Construction of the new copper flotation building continues to advance as planned and is on track to have the external structure fully enclosed before winter. Construction of the pipeline between the New Britannia and Stall mills also continues as planned.

As previously disclosed, Hudbay has identified the potential to produce gold from the New Britannia mill earlier in 2021 than originally expected. The refurbishment activities at the gold plant are ahead of schedule and commissioning of the gold plant is now expected in mid-2021, followed by ramp-up and first production in the third quarter of 2021. Copper flotation building construction activities continue to be on track for completion in August 2021, with commissioning and ramp-up expected during the second half of 2021. While the copper flotation building is being constructed, the company plans to install modular flotation cells at the gold plant to optimize copper recoveries as the company starts early processing of gold and copper-gold ores. The impact of the early gold production from the New Britannia mill continues to be evaluated and will be reflected in the company's annual production guidance update in early 2021.

Hudbay continues with the early mining of the gold zone at Lalor as part of stope sequencing in preparation for the start of the New Britannia gold mill. Once the New Britannia mill is ramped-up, average annual gold production from Lalor is expected to increase to over 150,000 ounces commencing in 2022 at cash costs and sustaining cash costs, net of by-product credits, of approximately $480 and $655 per ounce, respectively, during the first eight years of the gold plant's operation.

Pampacancha Update

The company completed the Pampacancha surface rights agreement with the local community of Chilloroya in February 2020. Since that time, the company has made significant progress on completing the Pampacancha individual land-user agreements and, as of September 30, 2020, approximately 79% of the land has been vacated and turned over to Hudbay (as compared to approximately one third as of June 30, 2020). During the first nine months of 2020, the company accrued approximately $95.9 million in growth spending in Peru relating to obligations under the local community surface rights agreement and the individual land-user agreements. As previously disclosed, the company's initial growth capital guidance for Peru of $70.0 million did not include the cost of the individual land user agreements due to the ongoing nature of the negotiations and, as indicated by accrued expenditures to date, full year growth capital spending for Peru will exceed that initial guidance once all land user agreements are concluded. As stated in Hudbay's second quarter results, the Consulta Previa consultation process has been impacted by the Peruvian government declared state of emergency, and as a result, the company expects a Pampacancha production start date of early 2021.

Constancia Regional Exploration

Constancia North Drilling

Hudbay has recently completed a follow-up drill program at Constancia North to continue to test a possible extension of copper porphyry and high-grade skarn mineralization occurring within 300 metres of the northern edge of the current Constancia pit. The drill program was a follow-up to the drill intersections announced on March 30, 2020 and continued to intersect both skarn and porphyry mineralization as shown in the table below. Most of the drill holes intersected mineralization located along a southeast-northwest trending regional fault. The location of the intersections is shown in Figure 1. The results will be evaluated and integrated into the annual mineral reserve and resource estimate update for Constancia at the end of the first quarter of 2021.

Other Regional Exploration

Hudbay's patient and consistent approach to community negotiations has proven successful, demonstrating strong relationships with the neighbouring communities near Constancia and positioning the company well to gain access to other regional growth targets in Peru. After reaching an exploration agreement with the Quehuincha community in early 2019 and subsequently completing the Consulta Previa process, Hudbay has commenced site preparation work and expects to start a drill program on the Quehuincha North high-grade skarn target in November.

TSX, NYSE - HBM2020 No. 22

Rosemont Update

The appeal of the unprecedented Rosemont court decision continues to advance. After Hudbay and the U.S. government filed their respective initial briefs in June 2020 with the U.S. Court of Appeals for the Ninth Circuit in relation to the U.S. District Court for the District of Arizona's decision in July 2019, the plaintiffs filed their briefs in September. Hudbay and the U.S. government expect to file their final briefs in November. A final decision in the appeal process is expected in late 2021.

In October 2020, Hudbay commenced a drilling program on its wholly owned private land located in a historic mining district, called Helvetia, near its Rosemont project in Arizona. The focus of the program is two-fold: to complete condemnation drilling in the areas planned for power and water lines for Rosemont, and to test the Helvetia copper district for future exploration potential. The company will provide further updates as appropriate.

Senior Unsecured Notes Refinancing

On September 23, 2020, the company completed the offering of $600.0 million aggregate principal amount of 6.125% senior notes due April 2029 (the "New Notes"). The New Notes are governed by an indenture, dated as of September 23, 2020, among the company, the subsidiaries of the company party thereto as guarantors and U.S. Bank National Association, as trustee.

The proceeds from this offering were primarily used to redeem all $400.0 million of the outstanding 7.250% Redeemed Notes, including the payment of accrued and unpaid interest, a call premium of $7.3 million, and transaction costs associated with the New Notes.

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 combined unit cost are non-IFRS performance measures. These measures do not have a meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other issuers. These measures should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS and are not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. Other companies may calculate these measures differently.

Hudbay believes adjusted net earnings (loss) and adjusted net earnings (loss) per share better reflect the company's performance for the current period and are better indications of its expected performance in future periods. These measures are used internally by the company to evaluate the performance of its underlying operations and to assist with its planning and forecasting of future operating results. As such, the company believes these measures are useful to investors in assessing the company's underlying performance. The company provides adjusted EBITDA to help users analyze its results and to provide additional information about the company's ongoing cash generating potential in order to assess its capacity to service and repay debt, carry out investments and cover working capital needs. Net debt is shown because it is a performance measure used by the company to assess its financial position. Cash cost, sustaining and all-in sustaining cash cost per pound of copper produced are shown because the company believes they help investors and management assess the performance of its 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.

TSX, NYSE - HBM2020 No. 22

In the first half of 2020, a government-imposed shutdown of non-essential businesses led to a temporary suspension of the Constancia mining operations. As such, 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 calculations of adjusted net earnings (loss), adjusted EBITDA and cash costs.

Effective September 30, 2020 and for all comparably disclosed periods, Hudbay has included the period's deferred revenue amortization as a by-product credit to reflect the net cost of producing and selling the period's precious metals under its streaming arrangements as it believes doing so allows management and the company's investors to better evaluate the operating performance of the underlying operations as compared to its peers. The variable consideration adjustment required under IFRS 15 related to prior periods is not included as a by-product credits in the current period and hence is disclosed as an adjustment in the non-IFRS cash cost measure reconciliation.

For further details on these measures, including reconciliations to the most comparable IFRS measures, please refer to page 42 of Hudbay's management's discussion and analysis for the three and nine months ended September 30, 2020 available on SEDAR at www.sedar.com.
