Story continues

• During the quarter, amid an uncertain macroeconomic climate, the Company’s management team prudently elected to fortify its balance sheet with a bought deal equity financing. Net proceeds from the transaction of $104.3 million contributed to available liquidity at year-end of $261.7 million, including cash and cash equivalents of $111.7 million and $150.0 million of undrawn availability under the Company’s senior secured revolving credit facility

• The Company is reaffirming its 2024 production, operating cost, and capital expenditure guidance

“2023 was a cornerstone year in advancing our growth strategy,” stated David Strang, Chief Executive Officer. “Our investments over the past few years position us well for the future at both the Xavantina Operations, where we successfully completed the NX60 initiative, and at the Caraíba Operations with the completion of our mill expansion and the excellent progress made on the new external shaft for the Pilar Mine.”

“However, the most significant transformation in our consolidated production profile and cash flows is projected to begin in the second half of this year when production is scheduled to commence at the Tucumã Project. With physical completion at over 90% and capital expenditures on the project starting to wind down, we are approaching an exciting inflection point when we expect to see these investments begin to yield strong shareholder returns.”

FOURTH QUARTER AND FULL YEAR 2023 REVIEW

• Organic Growth Projects

  • The Company continued to make significant construction progress at its Tucumã Project, achieving over 90% physical completion as of February 2024. With production of copper concentrate on schedule to commence in H2 2024, the Company’s transition from construction to commissioning is underway. Key milestones include:

    • Site fully energized in January 2024 following commissioning of the main substation and completion of the 16-kilometer power line tie-in with the national grid

    • Pre-stripping activities continue to track ahead of schedule with approximately 25,000 tonnes of sulphide ore stockpiled for process plant commissioning as at the end of February 2024

    • Mechanical completion and sub-component commissioning (lubrication, hydraulic, electrical, instrumentation and automation systems) continues to progress on schedule

    • Dry commissioning of the crushing circuit, encompassing the primary and secondary crushers as well as screening and conveyance systems, was completed in February 2024, approximately one month ahead of schedule

    • The total direct project capital estimate remains approximately $310 million

    • To date, the Tucumã Project has recorded no lost-time injuries with over three million hours of work completed since 2022

  • At the Caraíba Operations, the Company made important advancements on its Pilar 3.0 initiative during the quarter. This initiative aims to transform the Pilar Mine into a two-mine system capable of sustaining annual ore production levels of approximately 3.0 million tonnes

    • The Caraíba mill expansion, which is expected to increase mill throughput capacity from 3.2 to 4.2 million tonnes per annum, was successfully completed in December 2023 with design capacity achieved by year-end

    • Following the completion of the head-frame, winders and supporting surface infrastructure, the main shaft sinking phase for the Pilar Mine’s new external shaft commenced as planned in December 2023. The new external shaft component of the Pilar 3.0 initiative is fully contracted, and projected capital expenditures are within budget

  • The Xavantina Operations’ NX60 initiative was successfully completed in 2023. As a result, the Company achieved record gold production for the year and expects to sustain annual gold production levels of 55,000 to 60,000 ounces moving forward

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 year ended December 31, 2023 and the Reconciliation of Non-IFRS Measures section at the end of this press release.
(2) Copper C1 cash cost including foreign exchange hedges (per lb) in Q4 2023 and Fiscal 2023 were $1.59 and $1.68, respectively, compared to $1.59 in Q4 2022 and $1.67 in Fiscal 2022.}

2024 PRODUCTION AND COST GUIDANCE^(*)

The Company’s 2024 production guidance reflects the ongoing execution of its organic growth strategy, including the successful completion of the Xavantina Operations’ NX60 initiative as well as the anticipated completion of the Tucumã Project, which remains on track to commence production in H2 2024. As a result, the Company expects to deliver consolidated copper production of 59,000 to 72,000 tonnes in concentrate and gold production of 55,000 to 60,000 ounces.

The Company’s 2024 copper C1 cash cost guidance on a consolidated basis is $1.50 to $1.75. This range incorporates several key updates relative to previous 2024 C1 cash cost projections, including a revised copper C1 cash cost calculation methodology, as detailed in the Company’s press release dated February 21, 2024.

At the Xavantina Operations, the gold C1 cash cost guidance range of $550 to $650 reflects improved fixed cost efficiencies driven by higher expected gold production, partially offsetting the impact of planned decreases to mined and processed gold grades. The gold AISC guidance range for 2024 is $1,050 to $1,150.

The Company’s updated 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.

2024 CAPITAL EXPENDITURE GUIDANCE^(*)

2024 capital expenditures are expected to decrease to a range of $299 to $349 million due to the anticipated completion of the Tucumã Project, which is on track to commence production in the H2 2024. As a result, capital spend is expected to be weighted towards H1 2024.

The Company’s capital expenditure guidance includes an estimated $30 to $40 million allocated to consolidated exploration programs. This allocation includes approximately $20 million designated for drilling activities at the Caraíba Operations, including expenditures related to the Curaçá Valley nickel exploration program. Additionally, the Company has budgeted approximately $6 million for the first phase of work at the Furnas Project.

Capital expenditure guidance assumes an exchange rate of 5.10 USD:BRL for the Tucumã Project based on designated 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 below are in USD millions.

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.
