FORTUNA MINING CORP.

Fortuna was founded in 2005 by Simon Ridgway, Mario Szotlender, and Jorge Ganoza. Ganoza is a fourth-generation miner from a Peruvian family that has owned and operated several gold, silver, and base metals mines.

Fortuna acquired its underground Caylloma silver-lead-zinc mine in 2005, which started production in 2006. Also in 2006, it acquired a 76 percent stake in the San Jose silver-gold Project in Oaxaca, Mexico, which would become the San Jose Mine. Construction on the underground mine began in 2010, with production starting in 2011.

In 2010, Fortuna migrated from the TSX Venture Exchange to the Toronto Stock Exchange (TSX: FVI). The following year, Fortuna began trading on the New York Stock Exchange (NYSE: FSM).

In 2016, Fortuna acquired Goldrock Mines, an acquisition that included the open pit Lindero Gold Project in Argentina. In September 2017, the company announced it would move forward with construction, and in 2020, the Lindero Mine poured first gold.

In 2021, Fortuna expanded its reach beyond the Americas by acquiring West Africa-focused mining company Roxgold, including the underground Yaramoko Gold Mine in Burkina Faso and the advanced open-pit Séguéla Gold Project in Côte d'Ivoire, which became Fortuna’s fifth operating mine when it poured its first gold in May 2023.

In September 2023, Fortuna acquired Chesser Resources, including the Diamba Sud Gold Project in Senegal, one of the new and emerging gold discoveries in the region, further expanding Fortuna’s presence in West Africa.

In 2024, the company rebranded as Fortuna Mining to reflect their transition away from silver production. In early2025, the company said that it's West Africa gold mining operations made up two-thirds of the business, and they sold the San Jose silver mine in Mexico.

In April 2025, Fortuna completed the sale of the San Jose Mine in Mexico, which had been scheduled for progressive closure during the year. The company also divested the Yaramoko Mine in Burkina Faso, where exploration activities had already concluded, marking Fortuna’s full exit from the country.In October 2025, Fortuna reported the results of a Preliminary Economic Assessment for its Diamba Sud Gold Project in Senegal, followed by the release of a supporting technical report in November.
