Its three operating mines are Séguéla in Côte d’Ivoire, Lindero in Argentina and Caylloma in Peru; its projects and exploration also extend into Senegal and other parts of Latin America and West Africa.[1]+3

Products & services

Fortuna Mining Corp.’s products are gold, silver, lead, and zinc. Its Séguéla and Lindero mines produce gold, while Caylloma produces silver-lead and zinc concentrates. At Lindero, ore is crushed and agglomerated, heap-leached, treated through SART and ADR circuits, and smelted into gold doré bars.[8][9] The Caylloma technical report forecasts sulfide-ore recoveries of 82% for silver, 89% for lead, and 89% for zinc.[10]

In 2025, the company reported production of 317,001 gold-equivalent ounces (GEO); Séguéla produced 152,426 ounces of gold, while Caylloma produced 1,018,809 ounces of silver, 34.0 million pounds of lead, and 48.2 million pounds of zinc.[7][6] For 2026, Fortuna’s guidance is 281,000–305,000 GEO, comprising 160,000–170,000 ounces of gold at Séguéla, 92,000–102,000 ounces at Lindero, and 800,000–1,000,000 ounces of silver, 25–28 million pounds of lead, and 39–43 million pounds of zinc at Caylloma. The company’s materials report production and guidance, but do not provide product-mix percentages.[11]

Geographic presence

Fortuna Mining’s operating mines are located in Argentina (Lindero, Salta Province), Peru (Caylloma, Arequipa), and Côte d’Ivoire (Séguéla, Worodougou Region). These three countries were identified as operating locations in the company’s 2025 Q3 materials [2][1]; the mine locations are detailed in the company’s technical reports [9]+2. The company also has the Diamba Sud project in Senegal’s Kédougou Region [1][13].

Fortuna lists its corporate office in Vancouver, Canada, its Latin America head office in Lima, Peru, and its West Africa head office in Abidjan, Côte d’Ivoire [14][15]. The available sources do not establish revenue or employee distribution by country. [9]+5

Business segments

Fortuna Mining Corp. reports its operating results on a geographic basis, with its continuing mining operations represented by the Séguéla gold mine in Côte d’Ivoire, the Lindero gold mine in Argentina, and the Caylloma silver and base-metals mine in Peru. Its mine-level sales disclosures provide a more specific view of these operations than the geographic segment presentation. San José and Yaramoko were classified as discontinued operations following their disposal in 2025.[16][6]

For FY2025, continuing-operations sales were US$947.1 million. Lindero contributed US$294.2 million (about 31.1%) and Caylloma US$133.1 million (about 14.1%); the remaining approximately US$519.8 million (54.9%) is an implied Séguéla contribution, calculated by subtracting the disclosed Lindero and Caylloma figures from total continuing sales. These approximate shares use reported sales and the residual calculation, rather than separately reported segment percentages.[6]

The latest current-year filings located as of October 2, 2026, cover Q2 2026, including the six months ended June 30, 2026; the FY2025 figures above are used for comparable full-year contributions.[17][8]

Company history

Fortuna Mining Corp.’s corporate lineage began as Jopec Resources Ltd., incorporated in British Columbia in 1990. The company adopted the name Fortuna Ventures Inc. in 1999 and became Fortuna Silver Mines Inc. in 2005. That year it acquired Minera Bateas and the Caylloma mine in Peru, which resumed production in 2006.[18][19]

Fortuna expanded into Mexico through its 2006 acquisition of a 76% interest in the San Jose project; the mine reached commercial production in 2011.[20][21] The 2016 acquisition of Goldrock Mines added Argentina’s Lindero project, which produced its first gold in 2020.[22][23]

In 2021, Fortuna acquired Roxgold, adding the producing Yaramoko mine in Burkina Faso and the Séguéla project in Côte d’Ivoire; Séguéla poured first gold in 2023.[24][25] The company acquired Chesser Resources in 2023, adding Senegal’s Diamba Sud project. In June 2024, it changed its name to Fortuna Mining Corp. to reflect its gold and silver business; in 2025, it completed the sale of Yaramoko.[26]+2 [18]+10
