VANCOUVER, British Columbia, Aug. 01, 2024 (GLOBE NEWSWIRE) — Ero Copper Corp. (TSX: ERO, NYSE: ERO) (“Ero” or the “Company”) is pleased to announce its operating and financial results for the three and six months ended June 30, 2024. Management will host a conference call tomorrow, Friday, August 2, 2024, at 11:30 a.m. eastern time to discuss the results. Dial-in details for the call can be found near the end of this press release.

HIGHLIGHTS

• The Company reached a major inflection point with the successful production of first saleable copper concentrate at the Tucumã Project in early Q3 2024. Ramp up to commercial production is now underway

• Second quarter copper production was 8,867 tonnes at C1 cash costs^(*) of $2.16 per pound of copper produced

• Gold production during the quarter was 16,555 ounces at C1 cash costs^(*) and All-in Sustaining Costs (“AISC”)^(*) of $428 and $842, respectively, per ounce produced

• Second quarter financial results were bolstered by stronger metal prices and a favorable exchange rate environment, which also contributed to another quarter of record gross profit at the Xavantina Operations 
  • Net loss attributable to the owners of the Company of $53.2 million, or $0.52 per share on a diluted basis
  • Adjusted net income attributable to the owners of the Company^(*) of $18.6 million, or $0.18 per share on a diluted basis
  • Adjusted EBITDA^(*) of $51.5 million

• Available liquidity at quarter-end was $169.8 million, including $44.8 million in cash and cash equivalents, $100.0 million of undrawn availability under the Company’s senior secured revolving credit facility, and $25.0 million of undrawn availability under the copper prepayment facility, entered into in May 2024

^(*) 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. Please refer to the Company’s discussion of Non-IFRS measures in its Management’s Discussion and Analysis for the three and six months ended June 30, 2024 and the Reconciliation of Non-IFRS Measures section at the end of this press release.

• The Company is reaffirming full-year production and copper cash cost guidance and updating other 2024 guidance ranges to reflect H1 2024 performance, including exceptional year-to-date unit costs at the Xavantina Operations driven by elevated gold grades
  • Gold C1 cash cost guidance is being reduced to $450 to $550 (from $550 to $650) per ounce of gold produced, and AISC guidance is being lowered to $900 to $1,000 (from $1,050 to $1,150) per ounce of gold produced
  • Full-year capital expenditure guidance is being narrowed to $303 to $348 million (from $299 to $349 million)

“With the Tucumã Project ramping up to commercial production and the Xavantina Operations continuing to deliver exceptional operating results, we are on track to achieve record copper and gold production this year,” said David Strang, Chief Executive Officer. “At the same time, gold prices continue to test new highs while gross profit margins in our copper business are benefiting from a historically tight concentrate market.

“This is an incredibly exciting time for our Company as the investments we’ve made over the last several years begin to yield tangible returns. Our team’s hard work and dedication have positioned us to capitalize on these favorable market conditions and crystallize value for our shareholders.”

SECOND QUARTER REVIEW

• Mining & Milling Operations
  • The Caraíba Operations processed 957,692 tonnes of ore grading 1.03% copper, producing 8,867 tonnes of copper in concentrate for the quarter after metallurgical recoveries of 90.2%
    • Mill throughput continued to benefit from the successful completion of the Caraíba mill expansion in late 2023 with tonnes processed up 12.2% quarter-on-quarter and 17.9% compared to Q4 2023
    • Higher processed tonnage contributed to a 9.6% increase in copper production quarter-on-quarter
  • The Xavantina Operations processed 40,446 tonnes of ore grading 14.00 grams per tonne, producing 16,555 ounces of gold in the quarter after metallurgical recoveries of 91.0%

• Organic Growth Projects

OPERATING AND FINANCIAL HIGHLIGHTS

^{(1) EBITDA, adjusted EBITDA, adjusted net income (loss) attributable to owners of the Company, adjusted net income (loss) per share attributable to owners of the Company, net (cash) debt, working capital, copper C1 cash cost, copper C1 cash cost including foreign exchange hedges, gold C1 cash cost and gold AISC are non- IFRS measures. These measures do not have a standardized meaning prescribed by IFRS and might not be comparable to similar financial measures disclosed by other issuers. Please refer to the Company’s discussion of Non-IFRS measures in its Management’s Discussion and Analysis for the three and six months ended June 30, 2024 and the Reconciliation of Non-IFRS Measures section at the end of this press release.
(2) Copper C1 cash cost including foreign exchange hedges was $2.16 in Q2 2024 (Q2 2023 – $1.55) and $2.22 in YTD 2024 (YTD 2024 – $1.68).}

2024 PRODUCTION AND COST GUIDANCE^(*)

The Company is reaffirming its consolidated copper production guidance of 59,000 to 72,000 tonnes in concentrate, with production expected to be weighted towards H2 2024 largely due to the projected ramp-up of production at the Tucumã Project. Contributions from the Tucumã Project, combined with significantly lower concentrate treatment and refining charges, as well as a more favorable USD to BRL exchange rate, are expected to result in lower consolidated copper C1 cash costs in H2 2024 compared to H1 2024. As a result, the Company is reaffirming its full-year consolidated copper C1 cash cost guidance range of
$1.50 to $1.75 per pound of copper produced.

The Company is reaffirming its increased full-year gold production guidance range of 60,000 to 65,000 ounces. While slightly lower production is projected to result in higher unit costs in H2 2024 compared to H1 2024, the Company is lowering its 2024 gold cost guidance to reflect exceptional year-to-date unit cost performance. Full-year gold C1 cash cost guidance is now $450 to $550 (originally $550 to $650) per ounce of gold produced, and AISC guidance has been reduced to $900 to $1,000 (from $1,050 to $1,150) per ounce of gold produced.

The Company’s cost guidance for 2024 assumes a foreign exchange rate of 5.00 BRL per USD, a gold price of $1,900 per ounce and a silver price of $23.00 per ounce.

^{* 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. Please refer to the Company’s most recent Annual Information Form and Management of Risks and Uncertainties in the MD&A for complete risk factors.
(1) Please refer to the section titled “Alternative Performance (Non-IFRS) Measures” within the MD&A.}

2024 CAPITAL EXPENDITURE GUIDANCE^(*)

The Company is narrowing its full-year capital expenditure guidance range to $303 to $348 million (from $299 to $349 million).

The 2024 capital expenditure guidance assumes an exchange rate of 5.10 USD:BRL for the Tucumã Project based on allocated foreign exchange hedges with a weighted average ceiling and floor of 5.10 and 5.23 USD:BRL, respectively. All other capital expenditures assume an exchange rate of 5.00 USD:BRL. Figures presented in the table below are 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. Please refer to the Company’s most recent Annual Information Form and Management of Risks and Uncertainties in the MD&A for complete risk factors.
⁽¹⁾ Includes approximately $11.7 million of taxes deemed non-recoverable.
⁽²⁾ Includes capitalized mining costs that were accelerated by over two months due to the early completion of pre-strip activities. This additional capital is expected to result in lower operating costs in H2 2024.

CONFERENCE CALL DETAILS

The Company will hold a conference call on Friday, August 2, 2024 at 11:30 am Eastern time (8:30 am Pacific time) to discuss these results.

Reconciliation of Non-IFRS Measures

Financial results of the Company are presented in accordance with IFRS. The Company utilizes certain alternative performance (non-IFRS) measures to monitor its performance, including copper C1 cash cost, copper C1 cash cost including foreign exchange hedges, gold C1 cash cost, gold AISC, 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.

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.
