PEA Reissuance On The Copperstone Mine

TORONTO - Minera Alamos Inc. announced the reissuance of the Preliminary Economic Assessment (PEA) on the Copperstone Mine in Arizona. The study demonstrates potentially robust post-tax economics which, due to pre-existing infrastructure on surface and underground, result in both low initial capital and an overall low capital intensity ratio on a per gold ounce basis. The project now also benefits from its significant tax assets and recently reduced royalty encumbrance while also having potential for resource expansion and further exploration success. The PEA supports the construction and development of a high-grade gold underground mining operation at Copperstone producing an average of 40,765 payable oz gold per year over its an initial approximate 6 year mine life.

This newly prepared PEA does not address or incorporate ongoing work and trade-off studies currently being evaluated by the Minera Alamos team but does reflect a reduction in the Net Smelter Royalty ("NSR") burden on the project as an existing 1.5% NSR was extinguished since the first publication of the PEA by Sabre Gold Mines in 2023. Furthermore, in light of the significant move in gold prices in the last 18 months, the study includes a sensitivity analysis that takes into account gold prices ranging from $1,000/oz to $3,000/oz compared to the original study that had a gold price sensitivity range of $1,600/oz to $2,000/oz.
