  • The Company achieved significant milestones across its organic growth projects

    • Construction of the Tucumã Project progressed significantly, reaching 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. The total direct project capital estimate remains unchanged at approximately $310 million
    • The Caraíba mill expansion, which is expected to increase mill throughput capacity from 3.2 to 4.2 million tonnes per annum, was completed in December 2023 with design capacity achieved by year-end
    • Following the completion of 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
  • 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

  • Mining & Milling Operations
    • The Caraíba Operations processed 3.2 million tonnes of ore grading 1.49% copper, producing 43,857 tonnes of copper in concentrate for the year after metallurgical recoveries of 91.4%
      • Higher mill throughput volumes and processed copper grades during the fourth quarter resulted in copper production of 11,760 tonnes in concentrate, representing an increase of 9.2% compared to the third quarter
      • Full-year mill throughput volumes increased 12.8%, partially offsetting the impact of a planned decrease in mined and processed copper grades compared to 2022
    • The Xavantina Operations processed 136,002 tonnes of ore grading 15.13 grams per tonne, producing a record 59,222 ounces of gold in 2023 after metallurgical recoveries of 89.5%
      • Fourth quarter processed gold grades continued to exceed expectations, averaging 17.18 grams per tonne and resulting in production of 16,867 ounces for the quarter
      • The successful completion of the NX60 initiative contributed to increases in processed gold grades and gold production of 98.8% and 38.8%, respectively, compared to 2022
  • 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

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.

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.

For additional details please refer to the Company’s discussion of non-IFRS and other performance measures in its Management’s Discussion and Analysis for the year ended December 31, 2023 which is available on SEDAR at www.sedar.com and on EDGAR at www.sec.gov.

The risks discussed in this press release and in the AIF are not exhaustive of the factors that may affect any of the Company’s forward-looking statements. Although the Company has attempted to identify important factors that could cause actual results, actions, events, conditions, performance or achievements to differ materially from those contained in forward-looking statements, there may be other factors that cause results, actions, events, conditions, performance or achievements to differ from those anticipated, estimated or intended.

Forward-looking statements are not a guarantee of future performance. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Forward-looking statements involve statements about the future and are inherently uncertain, and the Company’s actual results, achievements or other future events or conditions may differ materially from those reflected in the forward-looking statements due to a variety of risks, uncertainties and other factors, including, without limitation, those referred to herein and in the AIF under the heading “Risk Factors”.

The Company’s forward-looking statements are based on the assumptions, beliefs, expectations and opinions of management on the date the statements are made, many of which may be difficult to predict and beyond the Company’s control. In connection with the forward-looking statements contained in this press release and in the AIF, the Company has made certain assumptions about, among other things: favourable equity and debt capital markets; the ability to raise any necessary additional capital on reasonable terms to advance the production, development and exploration of the Company’s properties and assets; future prices of copper, gold and other metal prices; the timing and results of exploration and drilling programs; the accuracy of any mineral reserve and mineral resource estimates; the geology of the Caraíba Operations, the Xavantina Operations and the Tucumã Project being as described in the respective technical report for each property; production costs; the accuracy of budgeted exploration, development and construction costs and expenditures; the price of other commodities such as fuel; future currency exchange rates and interest rates; operating conditions being favourable such that the Company is able to operate in a safe, efficient and effective manner; work force continuing to remain healthy in the face of prevailing epidemics, pandemics or other health risks, political and regulatory stability; the receipt of governmental, regulatory and third party approvals, licenses and permits on favourable terms; obtaining required renewals for existing approvals, licenses and permits on favourable terms; requirements under applicable laws; sustained labour stability; stability in financial and capital goods markets; availability of equipment; positive relations with local groups and the Company’s ability to meet its obligations under its agreements with such groups; and satisfying the terms and conditions of the Company’s current loan arrangements. Although the Company believes that the assumptions inherent in forward-looking statements are reasonable as of the date of this press release, these assumptions are subject to significant business, social, economic, political, regulatory, competitive and other risks and uncertainties, contingencies and other factors that could cause actual actions, events, conditions, results, performance or achievements to be materially different from those projected in the forward-looking statements. The Company cautions that the foregoing list of assumptions is not exhaustive. Other events or circumstances could cause actual results to differ materially from those estimated or projected and expressed in, or implied by, the forward-looking statements contained in this press release.

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.
