Sierra Metals Inc. (TSX: SMT | OTCQX: SMTSF | BVL: SMT) (“Sierra Metals” or the “Company”) announces that it will hold a special meeting of shareholders (the “Special Meeting”) on January 31, 2025. The Company has set a record date for the Special Meeting of December 30, 2024.

The purpose of the Special Meeting is to seek authorization from the Company’s shareholders to enable the Board of Directors (the “Board”) to consider a consolidation of all of the Company’s issued and outstanding common shares (“Common Shares”) at a ratio of one post‐consolidation share for up to every twenty pre‐consolidation shares (the “Consolidation”). Shareholders will be requested at the Special Meeting or any adjournment thereof, to consider and, if thought fit, pass, with or without amendment, a special resolution approving the Consolidation. Following the Special Meeting, the Board expects to exercise its discretion to implement the Consolidation on such a date and time as the Board may determine. Additional details in respect of the proposed Consolidation will be included in a management information circular which is being mailed to shareholders in compliance with applicable laws and will be available under the Company’s profile on SEDAR+ (www.sedarplus.ca).

The Board believes it is in the best interests of the Company to be in a position to complete the Consolidation to provide the Company with greater flexibility for future corporate activities, enhance the marketability of the Common Shares as an investment and lead to increased interest by a broader spectrum of potential investors, thereby increasing the Company’s ability to secure additional financing for operational and growth initiatives.

Over the past 24 months, Sierra Metals has successfully stabilized, optimized and improved its operations, resulting in a lower cost structure, increased efficiencies and profitability across the Company. During this period, the Company, among its many achievements, has safely delivered the following:

• Yauricocha Mine: increased throughput rates to full capacity of 3,600 tonnes per day (30% increase) which has increased metal production and lowered costs.
• Bolivar Mine: increased throughput rates to consistently produce at full capacity of 5,000 tonnes per day with plans underway to add tailing facilities to increase throughput capacity by 50% to 7,500 tonnes per day.
• Growing mineral reserves and resources: provided an updated NI 43-101 compliant mineral reserve and resource estimate for Yauricocha and Bolivar which indicates both operations have significant reserves and resources that underpin the foundation for growth.
• Divested Cusi Mine: the divesture for cash consideration of US$2.5 million allows the Company to focus resources on growing its core operations, with the possibility of a steady future revenue stream in the form of a 2% net smelter royalty from the Cusi Mine.
• Optimized balance sheet: recapitalized its balance sheet by refinancing its long-term debt facilities and completing an equity private placement with broad support from insiders and existing shareholders.
• Strengthened Leadership: to lead and execute Sierra’s growth phase, the Company has attracted a new CEO, CFO, and senior management team, and revitalized its board of directors.

Ernesto Balarezo, CEO of Sierra Metals, comments, “Over the past two years, Sierra Metals has been diligently delivering strong operating and financial results in a safe and responsible manner. Our strong financial position has us well positioned to focus on a period of organic growth at our two mines. The momentum we have generated across our business is poised to continue in 2025. As we embark on our next phase of growth, we believe the proposed share consolidation will provide an attractive entry point for potential new institutional investors and retail shareholders.”

The implementation of any Consolidation is subject to Sierra Metals receiving all required approvals, including support from shareholders at the upcoming Special Meeting, and the approval of the Toronto Stock Exchange. If the approvals required for the Consolidation are obtained and the Board decides to implement the Consolidation, the Consolidation will occur at a time determined by the Board and additional information in respect of the Consolidation will be announced by the Company.
