“We continued to deliver on our full-year operating plan during the second quarter while making significant progress on our organic growth initiatives,” said David Strang, Chief Executive Officer. “Despite softer copper prices and a significant strengthening of the BRL, excellent performance at our operations translated into solid operating margins and financial results for the quarter.

“Looking ahead, we anticipate a stronger second half of 2023 as we target commissioning of the new ball mill for our plant expansion project at the Caraíba Operations during the fourth quarter, and produce first ore from the recently developed Matinha vein at the Xavantina Operations.

“Construction of the Tucumã Project continues to advance on schedule and is nearing the halfway mark at approximately 45% physical completion. Electromechanical assembly of the process plant is now underway, and mine pre-strip remains on track to reach first sulphide ore in the fourth quarter of this year, as planned. At the Caraíba Operations, we completed the pre-sink phase of development at the new external shaft, achieving approximately 25% physical completion as of quarter-end. We are now in the process of hoisting the pre-assembled headframe to commence main shaft sinking activities prior to year-end.

“As the world’s focus on security of critical minerals supply chains grows more urgent, the timing of our growth trajectory appears increasingly favorable. We are proud to produce some of the lowest carbon-intensity metals in the world and remain on track to double copper production to over 100,000 tonnes in 2025 and achieve higher sustained gold production levels of 55,000 to 60,000 ounces per year beginning in 2024.”

SECOND QUARTER REVIEW

• Mining & Milling Operations
  • The Caraíba Operations processed 840,821 tonnes of ore grading 1.55% copper, producing 12,004 tonnes of copper in concentrate during the quarter after metallurgical recoveries of 92.0%
    • Higher mined tonnage and copper grades due to planned stope sequencing drove an increase in copper production of nearly 30% quarter-on-quarter
  • The Xavantina Operations processed 34,377 tonnes of ore grading 13.20 grams per tonne, delivering 12,333 ounces of gold production after metallurgical recoveries of 84.6%
    • Processed gold grades increased over 11% quarter-on-quarter and 100% year-on-year
    • Metallurgical recoveries were impacted by elevated in-process inventory at quarter-end as well as elevated carbon content in several high-grade stopes mined and processed during the period
    • By-product silver production for the period was 8,579 ounces
      

• Organic Growth Projects
  • The Company significantly advanced the construction of its Tucumã Project, which remains on schedule, achieving physical completion of approximately 45% as of quarter-end, up from approximately 30% at the end of Q1 2023
    • Mine pre-stripping is advancing as planned with over 5 million tonnes, or approximately 35% of total planned pre-strip volume, completed as of quarter-end. The mine remains on track to reach first sulphide ore in Q4 2023
    • Civil works are also tracking to schedule with foundations for the primary crusher, ball mill and flotation areas completed during the quarter. Electromechanical assembly commenced just after quarter-end, as planned
    • Total project capital estimate remains unchanged at approximately $305 million based on over 95% visibility of planned capital expenditures
    • Workforce training programs, established 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, are now well underway with nearly 100% of employees and contractors expected to come from within Brazil, including approximately two-thirds from communities surrounding the Tucumã Project
  • At the Caraíba Operations, the Company is focused on advancing its Pilar 3.0 initiative, designed to support sustained annual ore production levels of 3.0 million tonnes. The components of Pilar 3.0 include (i) Project Honeypot, an engineering initiative focused on recovering higher-grade material in the upper levels of the Pilar Mine, (ii) an expansion of the Caraíba mill from 3.0 to 4.2 million tonnes of annual throughput capacity, and (iii) construction of a new external shaft to service the lower levels of the Pilar Mine, including the Deepening Extension Zone

OPERATING AND FINANCIAL HIGHLIGHTS

2023 PRODUCTION AND COST GUIDANCE^(*)

The Company is reaffirming its 2023 copper production guidance for the Caraíba Operations of 44,000 to 47,000 tonnes of copper in concentrate. Mill throughput volumes are expected to be slightly lower in Q3 2023 compared to Q2 2023 and higher in Q4 2023 due to the anticipated commissioning of the new ball mill. Combined with expected copper grade variations related to planned stope sequencing, copper production is expected to decrease slightly in Q3 2023 before increasing in the last quarter of the year.

The Company is also maintaining its full-year C1 cash cost guidance for the Caraíba Operations of $1.40 and $1.60 per pound of copper produced. Unit operating costs are expected to be slightly higher in Q3 2023 compared to Q2 2023 and lowest in the last quarter of the year due to anticipated variations in quarterly mined and processed copper grades as well as total copper production.

At the Xavantina Operations, the Company is reaffirming its 2023 gold production guidance range of 50,000 to 53,000 ounces with slightly higher gold production expected in H2 2023 due to increased mill throughput volumes following the expected commencement of production from the Matinha vein.

The Company is also maintaining its full-year C1 cash cost guidance for the Xavantina Operations of $475 and $575 per ounce of gold produced and adjusting its AISC guidance range to $1,000 to $1,100 per ounce of gold produced to reflect the inclusion of sustaining lease payments and other miscellaneous sustaining expenses.

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.

2023 CAPITAL EXPENDITURE GUIDANCE^(*)

After conducting a detailed review of major projects and support infrastructure at the Caraíba Operations during the quarter, including infrastructure related to the Deepening, underground paste fill and tailings, the Company has elected to invest in various upgrades throughout H2 2023. These enhancements aim to bolster the Caraíba Operations’ ongoing projects and support expanded life-of-mine operating plans at the Pilar Mine. As a result, the Company is increasing its full-year capital expenditure guidance by $15 to $20 million.

The Company’s capital expenditure guidance for 2023 assumes a USD:BRL foreign exchange rate of 5.30 and has been presented below in USD millions.

^(*) Guidance is based on certain estimates and assumptions, including but not limited to, mineral reserve estimates, grade and continuity of interpreted geological formations and metallurgical performance.

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 National Instrument 43-101, Standards of Disclosure for Mineral Projects (“NI 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.
