Fortuna Mining Corp. - Form 6-K Filing

Fortuna Mining Corp. has filed a Form 6-K report detailing results from infill drilling at the Lindero Mine in Argentina. The drilling program, which extended beyond its initial scope due to successful outcomes, aimed to upgrade Inferred Mineral Resources below the current life-of-mine pit design. Several holes, including LDH-259 and LDH-272, confirmed significant gold mineralization extending below the existing pit design, with LDH-272 intersecting 0.96 g/t gold over 350 meters. The company is incorporating these results into an updated block model and pit design, expected by year-end, to support a revised life-of-mine plan and updated Mineral Reserve estimate. An updated Mineral Resource and Mineral Reserve estimate is planned for inclusion in the year-end consolidated report, with a release targeted for the first quarter of 2027. The Lindero deposit is characterized by a circular gold mineralization body extending over 300 meters below the surface, with higher gold grades associated with specific geological features. The report also includes detailed drilling data, quality assurance and quality control procedures, and standard forward-looking statements typical of mining company filings.
