Minera Alamos Advances Copperstone Mine Development with Key Regulatory Submission

Minera Alamos Inc. is making significant strides in the development of its Copperstone Mine project, as it submits a final Mine Plan of Operations amendment to align with U.S. federal regulations. This submission marks a crucial step in the company's efforts to advance the project, especially since it has already secured all key permits necessary for development, except for minor amendments regarding changes in processing technology. The ability to commence site development activities concurrently with the review of this amendment underscores the company's proactive approach to project management and regulatory compliance.

The reissued Preliminary Economic Assessment (PEA), released in February 2025, serves as a strong indicator of the project’s economic potential, projecting an after-tax Net Present Value (NPV) of USD 66 million at a gold price of USD 1,800 per ounce. This figure could soar to as much as USD 200 million if gold prices reach USD 2,800 per ounce. The PEA also highlights an impressive Internal Rate of Return (IRR) that ranges from 53.6% to 152.7%, suggesting that the Copperstone Mine could be a highly lucrative venture. With engineering activities ramping up to optimize the mine’s restart and the installation of the processing plant, Minera Alamos is positioning itself for a successful operation in the near future, with an updated technical study slated for release in the fourth quarter of 2025.

In tandem with these developments, Minera Alamos is actively pursuing discussions for project financing to ensure that the Copperstone project is well-capitalized for its upcoming phases. The company is also focused on enhancing the mine's value through targeted drilling and resource expansion. Initial exploration efforts have already identified promising drilling targets near historic drill hole 06CS-20, which previously intersected gold mineralization. However, Minera Alamos acknowledges the distinction between identified mineral resources and reserves, emphasizing that further work is essential to establish economic viability.

In addition to the advancements at Copperstone, Minera Alamos wholly owns the Cerro de Oro oxide gold project, further diversifying its portfolio within the gold mining sector. As the company continues to optimize its operations and explore new opportunities, it remains committed to responsible mining practices and adhering to regulatory standards, ensuring sustainable growth in the competitive landscape of the mining industry.
