Commenting on the results, David Strang, CEO, stated, “2021 marked another exceptional year for Ero. In addition to delivering record copper production and financial results, our team made significant progress in solidifying transformational organic growth plans, placing the Company in a strong position to execute on initiatives targeting approximately 100,000 tonnes of annual copper production and 60,000 ounces of annual gold production by 2025.
“Building upon operational momentum, subsequent to year-end we bolstered our balance sheet with a $400 million senior unsecured notes offering, providing ample liquidity to fund our organic growth plans over the coming years. Near-term, we will be focused on commencing the construction of the Boa Esperança Project, which we expect to occur in Q2 2022, further advancing construction of the external shaft of the Pilar Mine, an integral component of our Pilar 3.0 initiative, and continuing to grow our asset base through ongoing exploration.
“As we look to the future, we are excited to solidify our position as one of the world’s cleanest and fastest growing copper producers. With decarbonization and tightening emission standards expected to drive significant copper demand growth in the years ahead, our fully-funded growth strategy leaves us well-positioned to be at the forefront of low carbon-intensive copper production.”

FOURTH QUARTER & FULL-YEAR REVIEW
- Mining & Milling Operations – strong Q4 operating results contributed to another year of record copper production
- The MCSA Mining Complex processed 646,319 tonnes of ore grading 2.01% copper, producing 11,918 tonnes of copper in concentrate during the quarter after metallurgical recoveries of 92.7%; full year 2021 copper production totaled 45,511 tonnes based on approximately 2.4 million tonnes processed at copper grades of 2.08% and metallurgical recoveries of 92.4%.
- Higher quarter-on-quarter copper production was driven primarily by increased mill throughput volumes related to (i) the ramp-up of mining activity and processing of stockpiled ore from the Surubim open pit mine and (ii) a return to higher mill capacity levels following the completion of preventative mill maintenance, which impacted mill throughput volumes in Q2 and Q3 of 2021.
- The NX Gold Mine processed 47,159 tonnes grading 6.24 grams per tonne, producing 8,544 ounces of gold after metallurgical recoveries of 90.3% and 5,859 ounces of silver produced as by-product; full year 2021 tonnes processed totaled 171,581 at an average grade of 7.27 grams per tonne, producing 37,798 ounces of gold after metallurgical recoveries of 94.2% and 25,031 ounces of silver produced as by-product.
- Commissioning of the NX Gold Mine’s paste-fill plant, where construction was completed in Q3 2021, continued during the fourth quarter and concluded in January 2022. The paste- fill plan is expected to improve overhand cut and fill mining operations and enhance pillar recovery throughout the mine.
- OrganicGrowthProjects – clear and fully-funded organic growth strategy
- During the fourth quarter, the Company finalized a redesign of the new external shaft of the Pilar Mine to allow for higher sustained production rates as part of the Pilar 3.0 initiative, which was announced subsequent to year-end. Plans to construct a larger shaft were driven by continued exploration success within the Deepening Extension Zone and in the upper levels of the Pilar Mine, enabling the creation of a two-mine system whereby the upper levels of the mine will be serviced by the existing shaft, while the Deepening Extension Zone will utilize the new, larger external shaft. Pilar 3.0 is expected to enable higher annual production volumes of 2.6 to 3.0 million tonnes compared to the current production rate of approximately 1.3 million tonnes per annum at the Pilar Mine.
- The Company announced that its Board of Directors approved the construction of the Boa Esperanca Project subsequent to year-end. Construction is expected to commence in Q2 2022, with first production anticipated in H2 2024.

The Company utilizes certain alternative performance (non-IFRS) measures to monitor its performance, 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 (per ounce), EBITDA, adjusted EBITDA, adjusted net income attributable to owners of the Company, adjusted net income per share, net (cash) debt, working capital and available liquidity. These performance measures have no standardized meaning prescribed within generally accepted accounting principles under IFRS and, therefore, amounts presented may not be comparable to similar measures presented by other mining companies. These non-IFRS measures are intended to provide supplemental 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 a non-IFRS performance measure used by the Company to manage and evaluate the operating performance of its copper mining segment and is calculated as C1 cash costs divided by total pounds of copper produced during the period. C1 cash costs includes total cost of production, transportation, treatment and refining charges, and certain tax credits relating to sales invoiced to the Company’s Brazilian customer on sales, net of by-product credits and incentive payments. C1 cash cost of copper produced per pound is widely reported in the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed in supplement to IFRS measures.
C1 cash cost of gold produced (per ounce)
C1 cash cost of gold produced (per ounce) is a non-IFRS performance measure used by the Company to manage and evaluate the operating performance of its gold mining segment and is calculated as C1 cash costs divided by total ounces of gold produced during the period. C1 cash cost includes total cost of production, net of by-product credits and incentive payments. C1 cash cost of gold produced per ounce is widely reported in the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed in supplemental to IFRS measures.
All-in Sustaining Cost of gold produced (per ounce)
All-in sustaining cost of gold produced (per ounce) is an extension of C1 cash cost of gold produced (per ounce) discussed above and is also a key performance measure used by management to evaluate operating performance of its gold mining segment. AISC of gold produced (per ounce) is calculated as AISC divided by total ounces of gold produced during the period. AISC includes C1 cash costs, site general and administrative costs, accretion of mine closure and rehabilitation provision, sustaining capital expenditures, sustaining leases, and royalties and production taxes. AISC of gold produced (per ounce) is widely reported in the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed in supplement to IFRS measures.
Earnings before interest, taxes, depreciation and amortization (EBITDA) and Adjusted EBITDA
EBITDA and adjusted EBITDA are non-IFRS performance measures used by management to evaluate its debt service capacity and performance of its operations. EBITDA represents earnings before finance expense, income taxes, depreciation and amortization. Adjusted EBITDA is EBITDA before the pre-tax effect of adjustments for non-cash and/or non-recurring items required in determination of EBITDA under its revolving credit facility for covenant calculation purposes.
Adjusted net income attributable to owners of the Company and Adjusted net income per share attributable to owners of the Company
“Adjusted net income attributable to owners of the Company” is net income attributed to shareholders as reported, adjusted for certain types of transactions that, in management’s judgment, are not indicative of our normal operating activities or do not necessarily occur on a recurring basis. “Adjusted net income per share attributable to owners of the Company” (“Adjusted EPS”) is calculated as “adjusted net income attributable to owners of the Company” divided by weighted average number of outstanding common shares in the period. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, the Company and certain investor and analysts use these supplemental non-IFRS performance measures to evaluate the normalized performance of the Company. The presentation of Adjusted EPS is not meant to substitute the net income (loss) per share attributable to owners of the Company (“EPS”) presented in accordance with IFRS, but rather it should be evaluated in conjunction with such IFRS measures.
Net (Cash) Debt
Net (cash) debt is a performance measure used by the Company to assess its financial position and ability to pay down its debt. Net (cash) debt is determined based on cash and cash equivalents, short-term investments, net of loans and borrowings as reported in the Company’s consolidated financial statements.
Working capital and Available liquidity
Working capital is calculated as current assets less current liabilities as reported in the Company’s consolidated financial statements. The Company uses working capital as a measure of the Company’s short-term financial health and ability to meet its current obligations using its current assets. Available liquidity is calculated as the sum of cash and cash equivalents, short- term investments and the undrawn amount available on its revolving credit facilities. The Company uses this information to evaluate the liquid assets available.

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.
