HIGHLIGHTS

Record Copper Production Result for 2021

  • At the MCSA Mining Complex, total production for 2021 was 45,511 tonnes of copper in concentrate, surpassing the high-end of full-year guidance of 42,000 to 45,000 tonnes; and,
  • At the NX Gold Mine, total production for 2021 was 37,798 ounces of gold, surpassing high-end of full-year guidance of 34,500 to 37,500 ounces of gold.

Updated mineral reserve estimate for Deepening Extension Zone enables the creation of a two-mine system at the Pilar Mine with redesigned larger external shaft

  • The creation of a two-mine system at the Pilar Mine, known as "Pilar 3.0", 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, expected to result in significant growth in total production from the mine;
  • Annual ore production from the Pilar Mine is now forecast to achieve approximately 3.0 million tonnes by 2026 versus the current production rate of approximately 1.3 million tonnes. From 2027 onwards, annual ore production is expected to range from 2.6 million to 3.0 million tonnes; and,
  • Pilar 3.0 results in the deferral of capital related to the construction of higher operating cost ore- sorting projects at N8/N9 and Siriema.

2022 Production, Cost and Capital Expenditure Guidance

  • 2022 MCSA Mining Complex production guidance of 43,000 to 46,000 tonnes of copper in concentrate at a C1 cash cost guidance range of $1.05 to $1.15 per pound of copper produced;
  • 2022 NX Gold Mine production guidance of 39,000 to 42,000 ounces of gold at C1 cash cost and all-in sustaining ("AISC") guidance ranges of $500 to $600 and $925 to $1,025 per ounce of gold produced, respectively; and,
  • Capital expenditures expected to total $330 to $375 million in 2022, including $39 to $46 million in consolidated exploration spend and $70 to $80 million towards the construction of the Boa Esperança Project expected to commence in Q2 2022, subject to approval by the Board of Directors of the Company. Also reflected in the 2022 capital expenditure guidance:
    • Ongoing construction of the larger external shaft and completion of the Phase 2 cooling project as part of Pilar Mine 3.0; and,
    • Commencement of the Caraíba Mill expansion to 4.2 million tonnes per annum in preparation for expanded operations at the MCSA Mining Complex.

5-Year Operating Outlook

  • Copper production is forecast to more than double 1 compared to the Company's 2021 results to a range of 92,000 to 102,000 tonnes of copper in concentrate in 2025, assuming contributions from the Boa Esperança Mine 2 ;

  • Copper C1 cash costs are expected to average approximately $1.05 1 per pound of copper produced on forecasted production totaling approximately 350,000 1 tonnes from 2022 to 2026;

  • Annual gold production is forecast to increase to a range of 55,000 to 60,000 ounces by 2024, an increase of over 50% 1 compared to 2021 results;

  • Gold C1 cash costs and AISC are expected to average approximately $515 1 and $675 1 , respectively, per ounce of gold produced with production totaling approximately 265,000 1 ounces from 2022 through 2026; and,

  • Key capital projects aimed at doubling copper production, positioning the MCSA Mining Complex for expanded operations, and achieving higher sustained gold production at the NX Gold Mine include:

    • Approximately $300 million for the construction of the Boa Esperança Project 2 ;

    • Approximately $250 million for the construction of Pilar 3.0 including the larger external shaft, associated infrastructure, ventilation, cooling and equipment plus an estimated $35 million for ancillary capital costs including contingency and third-party construction management costs;

    • Approximately $30 million to support expanded operations at the MCSA Mining Complex, including the expansion of mill capacity for the Caraíba Mill to 4.2 million tonnes per annum and long-term tailings storage capacity improvements to support the increased throughput and longer mine life; and,

    • Approximately $10 million to support higher sustained gold production of approximately 60,000 ounces at the NX Gold Mine as part of the Company's "NX 60" initiative.

1. Based on midpoint of guidance range(s).
2. Outlook assumes contributions from the Boa Esperança Mine. Construction of the Boa Esperança Project is expected to commence in Q2 2022 but remains subject to the approval of the Board of Directors of the Company.

Commenting on the results, David Strang, CEO, stated, "2021 was a pivotal year for Ero Copper. Our team delivered another year of record production results and laid the foundation for significant organic growth of copper and gold production in the years ahead. In addition to announcing the results of our optimized Feasibility Study on the Boa Esperança Project and demonstrating meaningful growth in our reserves and resources across our operating portfolio, we completed a redesign of the Pilar Mine, known as Pilar 3.0. Both projects fit with our focus on maximizing returns on invested capital ("ROIC"). In the case of Pilar 3.0, we have replaced a lower ROIC initiative, the ore sorting project, with a higher one. Likewise, at our NX Gold operations, we have initiated a project, known as NX 60, that is focused on sustaining longer term gold production of approximately 60,000 ounces per year by incorporating the new Matinha Vein into our mine plan from 2024 onwards.

"We are now well-placed to achieve the next stage of our growth — becoming a 100,000 tonne a year copper and 60,000 ounce a year gold producer by 2025 — while maintaining first quartile operating costs and industry-leading ROIC."

2021 PRODUCTION RESULTS

  • At the MCSA Mining Complex, approximately 2.4 million tonnes of ore grading 2.08% copper was processed during the year, resulting in 45,511 tonnes of copper in concentrate produced after average metallurgical recoveries of 92.4%;
    • Fourth quarter mill throughput of 646,319 tonnes of ore grading 1.99% copper resulted in 11,918 tonnes of copper in concentrate produced after average metallurgical recoveries of 92.7% during the period;
  • At the NX Gold Mine, 171,581 tonnes of ore grading 7.27 grams per tonne ("gpt") gold was processed during the year, producing 37,798 ounces of gold and 25,031 ounces of silver as by- product after average metallurgical recoveries of 94.2%;
    • Fourth quarter mill throughput of 47,159 tonnes of ore grading 6.24 gpt gold resulted in 8,544 ounces of gold produced and 5,859 ounces of silver produced as by-product after average metallurgical recoveries of 90.3% during the period;

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 National Instrument 43-101 Standards of Disclosure for Mineral Projects ("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.

Benton and Sokoman Initiate Drill Program at the Kraken Lithium Prospect on the Golden Hope JV; Spodumene-bearing Pegmatite Encountered in First Hole

Benton and Sokoman Initiate Drill Program at the Kraken Lithium Prospect on the Golden Hope JV; Spodumene-bearing Pegmatite Encountered in First Hole

Benton Resources Inc. (TSXV: BEX) ("Benton") and Sokoman Minerals Corp. (TSXV: SIC) (OTCQB: SICNF) ("Sokoman") together, (the "Alliance") are pleased to announce that the Alliance has commenced the Phase 1 diamond drilling program at the Kraken Lithium prospect on the Golden Hope JV project located in southwest Newfoundland near the village of Burgeo. The diamond drilling program is expected to consist of 1,000 to 2,000 metres of diamond drill core in 4-6 holes designed to test an extensive system of spodumene- bearing dykes which have been sampled over a strike length of two kilometres within a corridor measuring 1,000 metres in apparent width and open in all directions. The Alliance is also pleased to announce that the first hole, with planned drill depth of 350 m-400 m across stratigraphy, has intercepted several spodumene-bearing (an important source of lithium) dykes near surface and the hole continues. Pictures of the core will be posted on both Benton's and Sokoman's websites in order to keep shareholders engaged in its progress at the Kraken dyke swarm. The Alliance is very pleased with the progress thus far and is in the process of logging, cutting and sampling the core to be submitted for assay as soon as possible. Kraken is the first-ever high-grade lithium discovery in Newfoundland and Labrador, with surface grab samples returning grades from trace to 2.37% Li2O (see Alliance joint press release dated August 16, 2021). This is also the first Newfoundland drilling program designed to target lithium.

The Kraken Pegmatites are highly evolved, pegmatite swarms similar to the geological environment and setting of other large systems in the Appalachian belt, including the important deposits held by Piedmont Lithium Inc. in the Carolinas, eastern US, as well as in the geologically equivalent Avalonia Project being advanced by Ganfeng Lithium in the Caledonides of Ireland. All samples will be submitted to Actlabs in Ancaster, Ontario for analysis by Sodium Peroxide Fusion ICPOES + ICPMS.
