San Luis

Flagship high-grade gold-silver vein project in the Ancash Department of central Peru, acquired from SSR Mining through the purchase of four subsidiary companies under a share purchase agreement signed in November 2023 and closed in May 2024. The project is subject to a 4% net smelter returns royalty granted to SSR Mining, half of which the company may buy back for US$15 million prior to mine construction (reducing it to 2%), plus contingent consideration payable to SSR on drilling and feasibility milestones. An independent 2025 updated mineral resource estimate (effective January 15, 2025) reviewed the earlier 2009 estimate and reports Indicated and Inferred resources for the Ayelén, Ayelén HW, and Inés veins at a 3 g/t gold-equivalent cut-off.
