HIGHLIGHTS

• Record full-year copper production of 46,371 tonnes, including 12,664 tonnes produced in the fourth quarter, surpassed the Company’s 2022 production guidance range of 43,000 to 46,000 tonnes

• Copper C1 cash costs^(*) for the fourth quarter and full-year were $1.41 and $1.36, respectively, per pound of copper produced

• Gold production also marked a record 42,669 ounces in 2022, including 11,786 ounces produced in the fourth quarter, and exceeded the full-year guidance range of 39,000 to 42,000 ounces

• Gold C1 cash costs^(*) for the fourth quarter and full-year were $445 and $560, respectively, per ounce of gold produced. All-in Sustaining Costs (“AISC”)^(*) for the same periods were $1,096 and $1,124, respectively, per ounce of gold produced

• Fourth quarter and full-year cash flows from operations were $34.0 million and $143.4 million, respectively

• Fourth quarter and full-year adjusted EBITDA^(*) were $58.2 million and $208.6 million, respectively

• Fourth quarter and full-year adjusted net income attributable to owners of the Company^(*) were $22.2 million ($0.24 per share on a diluted basis) and $83.5 million ($0.91 per share on a diluted basis), respectively

• Capital expenditures were nearly $90 million in the fourth quarter as construction activity related to the Company’s strategic growth initiatives ramped up. Full-year capital expenditures, including deposits on contracts, were just under $300 million, below 2022 capital expenditure guidance of $308 million to $354 million, primarily due to the success of Project Honeypot and subsequent deferral of the delivery date for the new external shaft of Pilar Mine

• Available liquidity at year-end was $392.4 million, including cash and cash equivalents of $177.7 million, short-term investments of $139.7 million, and $75.0 million of undrawn availability under the Company’s senior secured revolving credit facility. Subsequent to year-end, the Company extended the maturity and increased the size of its senior secured revolving credit facility to $150.0 million, resulting in pro forma year- end liquidity of $467.4 million

• 2023 production, operating cost, and capital expenditure guidance reaffirmed

“Our 2022 financial results showcase record production levels amidst a backdrop of inflationary pressures experienced across the global mining industry over the past year,” said David Strang, Chief Executive Officer. “Despite encountering some unique obstacles related to our domestic smelter that necessitated a higher allocation of copper concentrate sales to the export market, resulting in reduced tax benefits during the year, we resumed domestic sales on a limited basis subsequent to year-end. With the added benefit of higher metal prices, we are witnessing stronger-than-expected operating margins as we enter 2023 and are well-positioned to execute on our growth strategy.

“At our Tucumã Project, road upgrade and drainage infrastructure completed at the end of the third quarter allowed us to build momentum during the rainy season with minimal down- time. As of year-end, we reached just over 20% physical completion and are ahead of schedule on pre-stripping activities. As a result of these efforts, we were able to commence concrete pours for the plant foundation subsequent to year-end.

“At the Pilar Mine, we revised our timeline for the new external shaft following the success of Project Honeypot and updates to Caraíba’s Strategic Life-of-Mine Plan. The Project Honeypot stopes added to our production plan have allowed us to maintain high margins while smoothing our capital profile during construction of the shaft, for which the delivery date has been deferred by approximately nine months.

“Given the scarcity of new copper development projects and extraordinary demand anticipated from global decarbonization efforts, the timing of our near-term growth plans is highly favorable. With these unprecedented market conditions as well as nearly $470 million in balance sheet liquidity as of February 2023, we remain focused on delivering peer-leading growth.”

FOURTH QUARTER & FULL-YEAR REVIEW

•    Mining & Milling Operations

• The Caraíba Operations achieved record full-year production of 46,371 tonnes of copper in concentrate, following strong year-end operating performance driven by the addition of high-grade Project Honeypot stopes to the fourth quarter production plan
  • Higher mined and process copper grades during the fourth quarter resulted in copper production of 12,664 tonnes in concentrate, representing an increase of approximately 13% compared to the third quarter
  • Full-year copper production exceeded 2022 copper production guidance range of 43,000 to 46,000 tonnes and reflect a year-on-year increase to mill throughput of nearly 500,000 tonnes of ore
• The Xavantina Operations delivered record quarterly and full-year gold production of 11,786 and 42,669 ounces, respectively
  • Fourth quarter gold production benefited from higher processed gold grades of 10.17 grams per tonne (“gpt”), representing an increase in grade of nearly 20% compared to the prior quarter
  • Full-year gold production, which surpassed 2022 gold production guidance range of 39,000 to 42,000 ounces, increased approximately 13% year-on- year due to higher mill throughput as well as higher mined and processed gold grades

•    Organic Growth Projects

• The Company continued to progress the construction of the Tucumã Project, which is advancing on schedule with over 20% physical completion achieved as of year- end
  • Mine pre-stripping accelerated during Q4 2022 with approximately 1.6 million tonnes of pre-stripping completed as of year-end, or approximately 12% of total. Waste dump construction is progressing on schedule with completion expected in Q3 2023
  • Completion of the on-site concrete batch plant and mobilization of the civil works contractor occurred subsequent to year-end with first foundations poured in February 2023
  • Approximately 55% of planned capital expenditures were under contract as of year-end, up from approximately 30% at the end of Q3 2022. An additional 25% of Feasibility Study capital expenditures remain in various stages of tendering or negotiation. Consistent with Q3 2022 project capital forecasts, total planned capital expenditures remain within 12% of pre- contingency Feasibility Study as of year-end
  • In partnership with The National Service for Industrial Training, a Brazilian non-profit organization focused on improving the competitiveness of Brazil’s manufacturing sector through technical and vocational education, the Company commenced comprehensive training programs within the city of Tucumã and surrounding communities to further develop skills within the local community that are expected to support the development and operation of the Tucumã Project

• During the quarter, the Company’s Pilar 3.0 initiative was significantly bolstered by the success of Project Honeypot as reflected in the Caraíba Operations’ 2022 Strategic Life-of-Mine (“LOM”) Plan (please refer to press release dated November 7, 2022). Project Honeypot, an engineering initiative focused on recovering higher- grade material in the upper levels of the Pilar Mine, is one of three projects that together are expected to enable the creation of a two-mine system at the Pilar Mine. The other two components of Pilar 3.0 include (i) construction of a new external shaft to access the Deepening Extension Zone and (ii) an expansion of the Caraíba mill to 4.2 million tonnes per annum
  • The addition of Project Honeypot into the LOM Plan drove a significant increase to the Caraíba Operations’ estimated mineral resources, mineral reserves and mine life, allowing the Company to defer the delivery date of the new external shaft by approximately nine months without impacting expected copper production
  • Construction of the new external shaft continued to advance well against the revised timeline with physical completion at approximately 20% as of year-end and approximately 35% of planned capital expenditures under contract or in the final stages of negotiation. Based upon current capital expenditure forecasts which reflect additional supplier and contractor quotes, construction of the new external shaft remains on budget
  • The Caraíba mill expansion remains on schedule with completion expected in Q4 2023

•    Subsequent Events

• In January 2023, the Company entered into a zero-cost collar program on 3,000 tonnes of copper per month for February through December of 2023. The collars establish a floor price at $3.50 per pound of copper on total hedged volumes of 33,000 tonnes of copper, representing approximately 75% of full-year production volumes. The program protects a meaningful portion of the Company’s revenue at the Company’s 2023 budget copper price which was used for capital, cash flow and liquidity planning purposes, while providing upside to increases in the copper price up to a cap of $4.76 per pound – within 5% of the all-time high copper price. The hedge contracts are financially settled on a monthly basis.
• Subsequent to year-end, the Company also closed its amended senior secured revolving credit facility (the “Amended Senior Credit Facility”), increasing its capacity from $75.0 million to $150.0 million and extending the maturity from March 2025 to December 2026. The Company also achieved improved terms on the Amended Credit Facility, including a 25 basis point reduction to the applicable margin on drawn funds and reduced standby fees on undrawn commitments.

2023 PRODUCTION AND COST GUIDANCE^(*)

In 2023, the Caraíba Operations are expected to produce 44,000 to 47,000 tonnes of copper in concentrate with higher mill throughput levels expected towards the end of the year following the anticipated completion of the Caraíba mill expansion in Q4 2023. As a result, copper production is expected to be slightly weighted towards H2 2023 with Q1 2023 expected to contribute the lowest amount of production of the year due to planned stope sequencing driving lower anticipated processed copper grades.

The Company’s 2023 C1 cash cost guidance range for the Caraíba Operations of $1.40 to $1.60 per pound of copper produced reflects (i) sales allocation of 100% of copper concentrate produced to the international market and (ii) elevated consumable cost input assumptions based on Q4 2022 consumable pricing. Q1 2023 C1 cash costs are expected to be slightly above the full-year guidance range due to the impact of lower anticipated copper grades and production during the quarter.

At the Xavantina Operations, the Company expects to produce 50,000 to 53,000 ounces of gold in 2023 with production expected to be lowest in Q1 2023 and slightly weighted towards H2 2023 due to higher mill throughput levels following the expected commencement of production from the Matinha vein during H2 2023.

The Xavantina Operations’ 2023 C1 cash cost guidance range of $475 to $575 per ounce of gold produced reflects the impact of significantly higher anticipated mined and processed gold grades in 2023 compared to 2022, partially offset by elevated consumable cost assumptions reflecting Q4 2022 consumable pricing. The Company’s AISC guidance range for 2023 is $725 to $825 per ounce of gold produced.

The Company’s cost guidance for 2023 assumes a USD:BRL foreign exchange rate of 5.30, a gold price of $1,725 per ounce and a silver price of $20.00 per ounce.

^{(1) These are non-IFRS measures and do not have a standardized meaning prescribed by IFRS and might not be comparable to similar financial measures disclosed by other issuers. See the Reconciliation of Non-IFRS Measures section at the end of this press release for additional information.}

2023 CAPITAL EXPENDITURE GUIDANCE^(*)

CAUTIONARY NOTES REGARDING MINERAL RESOURCE AND MINERAL RESERVE ESTIMATES

Unless otherwise indicated, all reserve and resource estimates included in this press release and the documents incorporated by reference herein have been prepared in accordance with 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (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. Canadian standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission (the “SEC”), and reserve and resource information included herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, this press release and the documents incorporated by reference herein use the terms “measured resources,” “indicated resources” and “inferred resources” as defined in accordance with NI 43-101 and the CIM Standards.

Further to recent amendments, mineral property disclosure requirements in the United States (the “U.S. Rules”) are governed by subpart 1300 of Regulation S-K of the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”) which differ from the CIM Standards. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system (the “MJDS”), Ero is not required to provide disclosure on its mineral properties under the U.S. Rules and will continue to provide disclosure under NI 43-101 and the CIM Standards. If Ero ceases to be a foreign private issuer or loses its eligibility to file its annual report on Form 40-F pursuant to the MJDS, then Ero will be subject to the U.S. Rules, which differ from the requirements of NI 43-101 and the CIM Standards.

Pursuant to the new U.S. Rules, the SEC recognizes estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources.” In addition, the definitions of “proven mineral reserves” and “probable mineral reserves” under the U.S. Rules are now “substantially similar” to the corresponding standards under NI 43-101. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that Ero reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms under the U.S. Rules are “substantially similar” to the standards under NI 43-101 and CIM Standards, there are differences in the definitions under the U.S. Rules and CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that Ero may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had Ero prepared the reserve or resource estimates under the standards adopted under the U.S. Rules.
