Montero Mining Finalizes Feasibility Study for Potrero Gold Project in Chile’s High-Potential Maricunga Belt

Montero Mining has finalized a detailed feasibility study for its Potrero Gold project located within Chile’s Maricunga Belt, a region known for hosting multiple high-grade gold deposits. The study confirms a robust project profile, with an estimated average annual gold production of 250,000 ounces over a 12-year mine life. Capital expenditures are projected at $280 million, while operating costs are expected to remain below $750 per ounce, supporting strong cash flow generation. The project’s resource base includes a measured and indicated mineral resource of 1.8 million ounces of gold at a grade of 2.5 grams per tonne, with an additional 300,000 ounces in the inferred category. These figures underscore the project’s scalability and potential for future expansions. The study also details a pre-tax net present value (NPV) of $620 million at a 5% discount rate, with an internal rate of return (IRR) of 17.4%, reinforcing its financial viability. The completion of the study positions Montero Mining as a key player in Chile’s evolving gold sector, which has seen renewed investor interest due to favorable regulatory developments and infrastructure improvements. The Maricunga Belt, adjacent to major gold producers like Barrick and Zijin Mining, continues to attract exploration activity, and the Potrero project could serve as a catalyst for further development in the region. Market participants have taken note, with gold equities such as GDX and AUY showing modest gains in early trading. The news adds to positive momentum in the precious metals space, particularly for junior explorers with advanced-stage assets in geopolitically stable jurisdictions. Montero's next steps include finalizing financing and permitting, with a potential start of construction in late 2026.
