Fortuna Mining Corp. Establishes Presence in Guyana Shield Through Quartzstone Earn-In Agreement

Fortuna Mining Corp. has entered into an earn-in agreement with Qstone Inc. to acquire up to a 70% interest in the Quartzstone Project, located in the Guyana Shield. This project encompasses 29,600 hectares and is situated in a region known for gold discoveries. Historical drilling has identified multiple high-grade, near-surface gold mineralization zones. Fortuna plans an initial exploration program, including airborne magnetic surveys, field programs, and a 5,000-meter diamond drilling program, with an approximate budget of US$5.5 million. To earn an initial 51% interest, Fortuna must complete 60,000 meters of drilling within four years and fund all expenditures. An additional 19% interest can be earned by funding a feasibility study within three years of the first option exercise. Fortuna has already paid a US$5 million non-refundable option premium. The project is subject to a 4.5% net smelter returns royalty to a prior owner. Detailed historical drill results and quality assurance/quality control information are provided, with Paul Weedon, Senior Vice President of Exploration, acting as the Qualified Person who has reviewed and approved the technical information.
