Adjusted EBITDA reached $218.8 million, more than double the prior year period.

Fortuna Mining Corp. reports a 15% year-over-year increase in consolidated Mineral Reserves after production depletion, driven mainly by strong results at Séguéla and the Diamba Sud gold project.

For 2026, Fortuna allocates US$12.2 million at Séguéla, US$3.7 million at Lindero/Arizaro, and US$8.8 million at Diamba Sud for Brownfields drilling, while advancing a feasibility study at Diamba Sud to support a construction decision by the end of the second quarter of 2026.

Fortuna Mining Corp. is a Canadian precious metals producer with three operating mines and exploration activities across Latin America and West Africa, focused on gold and silver production with an emphasis on environmental stewardship and social responsibility.
Fortuna Mining Corp. has entered an earn-in agreement with Qstone Inc. to acquire up to a 70% interest in the Quartzstone gold project in Guyana, a 29,600-hectare land package in a prolific greenstone belt. Historical drilling from 2010 to 2017 totaled 183 diamond holes over 23,190 meters and outlined multiple near-surface high-grade gold zones, with intercepts such as 27.78 g/t Au over 5.6 meters and 15.93 g/t Au over 13.2 meters.
Fortuna plans an initial exploration program of about US$5.5 million, including airborne geophysics, geochemical sampling, mapping, and 5,000 meters of diamond drilling along a 26-kilometer shear corridor. The company can earn a 51% interest by drilling at least 60,000 meters within four years while funding all project costs, then increase to 70% by solely funding a feasibility study within three years of exercising the first option. On signing, Fortuna paid Qstone a non-refundable US$5 million cash option premium, and the project is subject to a 4.5% net smelter returns royalty in favor of a prior owner.
Fortuna Mining Corp. furnished an updated Code of Conduct and Business Ethics outlining expectations for directors, officers, employees, and business partners. The Code covers speaking up, non-retaliation, anti-discrimination, harassment, workplace safety, protection of company assets, confidentiality, conflicts of interest, accurate recordkeeping, and responsible communications.
It also details rules on gifts and entertainment, anti-bribery and anti-corruption, fair competition, data privacy, and insider trading. The Code emphasizes environmental protection, sustainability, and human rights, and requires annual and onboarding compliance certificates. It was approved by the Board of Directors on November 4, 2025, and waivers are tightly controlled.
Fortuna Mining Corp. has renewed its normal course issuer bid, authorizing the repurchase of up to 15,227,869 common shares, equal to five percent of its 304,557,387 outstanding shares as of April 10, 2026. The renewed program begins on May 4, 2026, with any shares bought back through the New York Stock Exchange to be cancelled.
The company has also set up an instructed share purchase plan and an automatic share purchase plan with a broker to execute repurchases, including during blackout periods, in line with securities laws and stock exchange rules. A prior program allowed purchases of up to 15,347,999 shares, under which Fortuna had already repurchased 3,400,000 shares at a weighted-average price of US$9.53 per share, which were subsequently cancelled. Management states it sees buybacks as an appropriate use of funds when the share price does not reflect underlying value.
Fortuna Mining Corp. reported first quarter 2026 production of 72,872 gold equivalent ounces (GEO) from its Séguéla, Lindero, and Caylloma mines and reiterated its 2026 guidance of 281,000 to 305,000 GEO. Séguéla in Côte d’Ivoire produced 42,016 ounces of gold, benefiting from higher tonnes milled, stronger grades, and improved recovery of 93.4%.
Lindero in Argentina produced 21,545 ounces of gold, up 12% from the prior quarter, while maintaining a low strip ratio and building stockpiles ahead of a planned primary crusher foundation replacement expected to finish by the end of April 2026. Caylloma in Peru delivered 9,311 GEO, with silver production of 257,603 ounces and base metal output of 11.5 million pounds of zinc and 8.2 million pounds of lead.
Growth initiatives advanced across the portfolio. Séguéla is evaluating a plant expansion to 2.0–2.5 million tonnes per year and progressing the Sunbird underground project, including an initial Mineral Reserve and expanded 2026 capital budget by about $10 million for long-lead items. The Diamba Sud project in Senegal moved forward with early works and procurement, a feasibility study targeted for completion in the second quarter of 2026, and a pathway outlined toward a mid-2028 first gold pour.
