HIGHLIGHTS

Copper production of 10,057 tonnes at the MCSA Mining Complex at C1 cash costs^(*) of $0.94 per pound of copper produced during the quarter;
Gold production of 9,426 ounces at the NX Gold Mine at C1 cash costs^(*) of $538 per ounce of gold produced and All-in Sustaining Costs ("AISC")^(*) of $741 per ounce of gold produced;
Strong quarterly adjusted EBITDA^(*) of $72.9 million and adjusted net income attributable to owners of the Company^(*) of $45.7 million ($0.49 per share on a diluted basis);
Record quarterly cash flows from operations of $150.7 million driven by strong operating performance and a $100.0 million upfront payment related to the August 2021 closing of the $110 million streaming agreement with Royal Gold (as defined below) in relation to gold production from the NX Gold Mine (the "NX Gold Stream");

Announced results of optimized Feasibility Study for the Boa Esperança Project, doubling life- of-mine copper production compared to the 2017 Study (as defined below);
Repaid $100.0 million of principal on the $150.0 million senior secured revolving credit facility, resulting in available liquidity at quarter-end of $219.1 million, including $92.6 million of cash and cash equivalents, $26.4 million in short-term investments, and $100.0 million of undrawn availability under the senior secured revolving credit facility; and,
Tracking towards the high-end of the Company's reaffirmed 2021 production guidance ranges; lowering full-year AISC guidance for the NX Gold Mine to $650 to $725 per ounce of gold produced and updating 2021 capital expenditure guidance for the MCSA Mining Complex to reflect the acceleration of capital expenditures associated with key projects into Q4 2021 as well as the impact of inflationary pressures on capitalized development.

Commenting on the results, David Strang, CEO, stated, "The third quarter was instrumental in positioning our Company to execute on our growth strategy. We delivered on three important milestones during the quarter including the completion of an optimized Feasibility Study on the Boa Esperança Project, the closing of the previously announced $110 million NX Gold Stream, and the conclusion of mill maintenance at the MCSA Mining Complex in preparation for expanded operations. With the construction of the new external shaft at the Pilar Mine initiated on schedule in September and the planned commencement of early construction activities at the Boa Esperança Project expected to begin in Q2 2022 (subject to approval by the Company's Board of Directors), our team is working to double production while maintaining strong margins over the coming years.

"In preparation of these growth timelines, we have brought forward the second phase of our cooling project and made down payments for long-lead items related to the new external shaft for the Pilar Mine. While we, like the rest of the mining industry, are seeing global inflationary pressures impacting both operating and capital development costs, it remains to be seen whether this cost pressure is transitory or structural in nature. As a result of the acceleration of growth project capital and incorporating increases in development costs, we are updating our capital expenditure guidance for the full-year at the MCSA Mining Complex by approximately $20 million.

"With respect to the Deepening Extension Project, construction of the first phase of the shaft and other early civil works have commenced. Concurrently, we are finalizing the optimization efforts on the project including plans to increase the shaft's diameter. As a result of incorporating exceptional year-to- date drill results from the Deepening Extension and new drilling in the upper levels of the mine, our team has begun working on a longer-term initiative to potentially increased overall production volumes from the Pilar Mine.

"We have an exceptional asset portfolio and our team has worked hard to achieve peer-leading cost performance through optimization and innovation, principles that we are applying to the Deepening Extension and Boa Esperança Projects. While we expect the macro operating environment to remain dynamic, we are staking our success on the core values that have consistently delivered shareholder value: executing upon high-return and low-capital intensity projects."

Please refer to the Company's press releases dated June 30, 2021 and August 6, 2021 for additional information on the NX Gold Stream.

2021 PRODUCTION OUTLOOK^(*)

The Company is well-positioned to achieve the high-end of its reaffirmed 2021 production guidance ranges of:

42,000 to 45,000 tonnes of copper in concentrate at the MCSA Mining Complex
34,500 to 37,500 ounces of gold at the NX Gold Mine

During Q3 2021, the Company completed the second and final phase of preventative mill maintenance at the MCSA Mining Complex in preparation for expanded operations and higher mill throughput volumes, including from Surubim open pit mine where pre-stripping activity continued during the quarter. Initial production from the Surubim open pit, including the processing of ore stockpiled during pre-stripping, is expected to drive higher mill throughput volumes and lower average processed copper grades during Q4 2021.

The Company expects to achieve the high-end of its full-year production guidance at the NX Gold Mine despite lower planned grades in Q4 2021 due to mine sequencing within the Santo Antonio Vein.

2021 COST GUIDANCE^(*)

The Company is on track to achieve its reaffirmed 2021 C1 cash cost guidance ranges, which assume a USD:BRL foreign exchange rate of 5.00, a gold price of $1,750 per ounce and a silver price of $20.00 per ounce. The Company has lowered its 2021 AISC guidance range for the NX Gold Mine to reflect lower sustaining capital expenditures year-to-date.

	2021 Guidance
MCSA Mining Complex C1 Cash Cost Guidance (US$/lb)⁽¹⁾	$0.75 - $0.85
NX Gold Mine C1 Cash Cost Guidance (US$/oz)⁽¹⁾	$500 - $600
NX Gold Mine All-in Sustaining Cost (AISC) Guidance (US$/oz)⁽¹⁾	$650 - $725

⁽¹⁾ C1 Cash Costs and AISC are a non-IFRS measure - see the Notes section of this press release for additional information.

2021 CAPITAL EXPENDITURE GUIDANCE^(*)

The Company is reaffirming its full-year capital expenditure guidance for the NX Gold Mine and updating its 2021 capital expenditure guidance for MCSA Mining Complex to reflect the acceleration of: (i) the Phase 2 cooling project at the MCSA Mining Complex, (ii) long-lead item purchases related to the new external shaft of the Pilar Mine and (iii) early civil and road construction activities at the Boa Esperança project into Q4 2021. Capitalized development costs at the MCSA Mining Complex have also been updated to reflect inflationary pressures impacting consumables used in development activities. The capital expenditure guidance assumes a USD:BRL foreign exchange rate of 5.00 and has been presented below in USD millions.

MCSA Operations	2021 Guidance

NOTES

Non-IFRS measures

Financial results of the Company are prepared in accordance with IFRS. The Company utilizes certain non-IFRS measures, including C1 cash cost of copper produced (per lb), C1 cash cost of gold produced (per ounce), AISC of gold produced (per ounce), realized gold price, EBITDA, Adjusted EBITDA, Adjusted net income attributable to owners of the Company, Adjusted net income per share, net debt, working capital and available liquidity, which are not measures recognized under IFRS. The Company believes that these measures, together with measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. Non-IFRS measures do not have any standardized meaning prescribed under IFRS, and therefore they may not be comparable to similar measures employed by other companies. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

C1 cash cost of copper produced (per lb.)

C1 cash cost of copper produced (per lb) is the sum of production costs, net of capital expenditure development costs and by-product credits, divided by the copper pounds produced. C1 cash cost reported by the Company include treatment, refining charges, offsite costs, and certain tax credits relating to sales invoiced to the Company's Brazilian customer on sales. By- product credits are calculated based on actual precious metal sales (net of treatment costs) during the period divided by the total pounds of copper produced during the period. C1 cash cost of copper produced per pound is a non-IFRS measure used by the Company to manage and evaluate operating performance of the Company's operating mining unit and is widely reported in the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed in addition to IFRS measures.

C1 cash cost of gold produced (per ounce)

C1 cash cost of gold produced (per ounce) is the sum of production costs, net of capital expenditure development costs and silver by-product credits, divided by the gold ounces produced. By-product credits are calculated based on actual precious metal sales during the period divided by the total ounces of gold produced during the period. C1 cash cost of gold produced per ounce is a non-IFRS measure used by the Company to manage and evaluate operating performance of the Company's operating mining unit and is widely reported in the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed in addition to IFRS measures.

All-in Sustaining Cost of gold produced (per ounce)

All-in sustaining cost of gold produced (per ounce) is the sum of production costs, site general and administrative costs, accretion of mine closure and rehabilitation provision, sustaining capital expenditures, sustaining leases, and royalties and production taxes, net of silver by- product credits, divided by the gold ounces produced. By-product credits are calculated based on actual precious metal sales during the period divided by the total ounces of gold produced during the period. All-in sustaining cost of gold produced per ounce is a non-IFRS measure used by the Company to manage and evaluate operating performance of the Company's operating mining unit and is widely reported in the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed in addition to IFRS measures.

Earnings before interest, taxes, depreciation and amortization (EBITDA) and Adjusted EBITDA

EBITDA represents earnings before interest expense, income taxes, depreciation, and amortization. Adjusted EBITDA includes further adjustments for non-recurring items and/or items not indicative to the future operating performance of the Company. The Company believes EBITDA and adjusted EBITDA are appropriate supplemental measures of debt service capacity and performance of its operations.

Adjusted EBITDA is calculated by removing the following income statement items:

Foreign exchange loss (gain)
Share based compensation
NX Gold stream transaction fees
Incremental costs in response to COVID-19 pandemic

Adjusted net income attributable to owners of the Company and Adjusted net income per share attributable to owners of the Company

The Company uses the financial measure "Adjusted net income attributable to owners of the Company" and "Adjusted net income per share attributable to owners of the Company" ("Adjusted EPS") to supplement information in its condensed consolidated interim financial statements. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, the Company and certain investor and analysts use this information to evaluate the Company's performance. The Company excludes the following items from net income to provide a measure which allows the Company and investors to evaluate the operating results of the underlying core operations:

Share based compensation
Unrealized foreign exchange loss (gain) on USD denominated balances in MCSA
Unrealized loss (gain) on foreign exchange derivative contracts, net of tax
NX Gold stream transaction fees
Incremental costs in response to COVID-19 pandemic
Unrealized loss (gain) on interest rate derivative contracts

Net Debt

Net debt is determined based on cash and cash equivalents, short-term investments, restricted cash and loans and borrowings as reported in the Company's condensed consolidated interim financial statements. The Company uses net debt as a measure of the Company's ability to pay down its debt.

Working capital and Available liquidity

Working capital is determined based on current assets and current liabilities as reported in the Company's condensed consolidated interim financial statements. The Company uses working capital as a measure of the Company's short-term financial health and operating efficiency. Available liquidity includes the Company's cash and cash equivalents, short-term investments and undrawn revolving credit facilities in place.

Furthermore, such forward-looking statements involve a variety of known and unknown risks, uncertainties and other factors which may cause the actual plans, intentions, activities, results, performance or achievements of the Company to be materially different from any future plans, intentions, activities, results, performance or achievements expressed or implied by such forward-looking statements. Such risks include, without limitation the risk factors listed under the heading "Risk Factors" in the AIF.

Although the Company has attempted to identify important factors that could cause actual actions, events, conditions, results, performance or achievements to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events, conditions, results, performance or achievements to differ from those anticipated, estimated or intended.

The Company cautions that the foregoing lists of important assumptions and factors are not exhaustive. Other events or circumstances could cause actual results to differ materially from those estimated or projected and expressed in, or implied by, the forward-looking statements contained herein. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.

Forward-looking statements contained herein are made as of the date of this press release and the Company disclaims any obligation to update or revise any forward-looking statement, whether as a result of new information, future events or results or otherwise, except as and to the extent required by applicable securities laws.

CAUTIONARY NOTES REGARDING MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES

In accordance with applicable Canadian securities regulatory requirements, all mineral reserve and mineral resource estimates of the Company disclosed in this press release have been prepared in accordance with NI 43-101 and are classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards for Mineral Resources and Mineral Reserves, adopted by the CIM Council on May 10, 2014 (the "CIM Standards"). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. NI 43-101 differs significantly from the disclosure requirements of the Securities and Exchange Commission (the "SEC") generally applicable to U.S. companies. For example, the terms "mineral reserve", "proven mineral reserve", "probable mineral reserve", "mineral resource", "measured mineral resource", "indicated mineral resource" and "inferred mineral resource" are defined in NI 43-101. These definitions differ from the definitions in the disclosure requirements promulgated by the SEC. Accordingly, information contained in this press release may not be comparable to similar information made public by U.S. companies reporting pursuant to SEC disclosure requirements.

Mineral resources which are not mineral reserves do not have demonstrated economic viability. Pursuant to the CIM Standards, mineral resources have a higher degree of uncertainty than mineral reserves as to their existence as well as their economic and legal feasibility. Inferred mineral resources, when compared with measured or indicated mineral resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration. Pursuant to NI 43-101, inferred mineral resources may not form the basis of any economic analysis. Accordingly, readers are cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral reserve, or is or will ever be economically or legally mineable or recovered.
