Company Description
Fortuna Mining Corp. (NYSE: FSM, TSX: FVI) is a Canadian precious metals mining company active in Latin America and West Africa. According to the company’s public disclosures, Fortuna operates three mines and holds a portfolio of exploration projects in Argentina, Côte d’Ivoire, Mexico, and Peru, along with the Diamba Sud Gold Project in Senegal. The business focuses on producing gold and silver and describes sustainability, environmental stewardship, and social responsibility as central to its operations and stakeholder relationships.
Core operations and geographic footprint
Recent company news highlights three operating mines: the Séguéla Mine in Côte d’Ivoire, the Lindero Mine in Argentina, and the Caylloma Mine in Peru. Fortuna reports that Séguéla delivered record gold production and is a key contributor to its gold output. Lindero is an open pit operation where ore is placed on a leach pad, and Caylloma produces silver, lead, and zinc, which are converted into gold equivalent ounces for reporting purposes. The company has also disclosed the completion of the sale of the San Jose Mine in Mexico and the Yaramoko Mine in Burkina Faso, describing these as divestitures of short reserve-life assets.
Beyond its producing assets, Fortuna is advancing the Diamba Sud Gold Project in Senegal. A Preliminary Economic Assessment (PEA) filed under National Instrument 43-101 describes Diamba Sud as an open pit project with a conventional carbon-in-leach processing plant, targeting multiple deposits such as Area A, Area D, Karakara, Western Splay, Kassassoko, Moungoundi, and Southern Arc. The company has reported robust project economics for Diamba Sud and is progressing the project toward more advanced technical studies.
Production profile and metals mix
Fortuna reports production and guidance in gold equivalent ounces (GEO), a measure that combines gold, silver, lead, and zinc using specified metal price ratios. In its 2025 production update, the company stated that it achieved annual production guidance with 317,001 GEO from ongoing and divested operations, and 279,207 GEO from ongoing operations. Séguéla, Lindero, and Caylloma are identified as the ongoing operations contributing to this total. Séguéla produced a record 152,426 ounces of gold in 2025, above the upper end of its guidance range, while Lindero and Caylloma also contributed meaningful gold and silver-base metal output.
For 2026, Fortuna has outlined an outlook that includes GEO production from ongoing operations in a range it characterizes as a projected increase compared to 2025. The company also provides mine-level guidance for gold and silver-equivalent production and reports consolidated cash cost and all-in sustaining cost (AISC) ranges per GEO, presented as non-IFRS measures. These disclosures indicate a focus on gold as the primary revenue driver, supported by silver and base metals from Caylloma.
Growth projects and exploration
Fortuna emphasizes an organic growth pipeline centered on West Africa and Latin America. At Séguéla in Côte d’Ivoire, the company has reported expanded Mineral Reserves and Mineral Resources, including Proven and Probable Mineral Reserves totaling 13.0 million tonnes containing 1.2 million ounces of gold as of October 31, 2025. Measured and Indicated Mineral Resources, exclusive of reserves, and Inferred Resources have also increased, with key contributions from the Sunbird and Kingfisher deposits. Mineralization at these deposits is described as remaining open in multiple directions, and Fortuna has initiated underground studies and plant expansion evaluations to support potential mine life extension and higher throughput.
At Diamba Sud in Senegal, Fortuna has completed and filed a NI 43-101 technical report supporting the PEA. The assessment outlines an 8.1-year life-of-mine plan with open pit mining and a central processing facility. The company reports that Diamba Sud’s Mineral Resource estimate includes Indicated and Inferred Resources across several deposits, and that exploration drilling at the Southern Arc and other areas continues to test extensions and new targets. Fortuna has also disclosed budgets for early works and exploration at Diamba Sud, including camp expansion, engineering activities, and drilling programs aimed at upgrading resources and extending the projected production profile.
Operational performance and financial context
In its third quarter 2025 results, Fortuna reported gold equivalent production from continuing operations, along with sales, mine operating income, operating income, and net income from continuing operations. The company discusses cash cost per GEO, AISC per GEO, adjusted EBITDA, and free cash flow from ongoing operations as non-IFRS financial measures, providing definitions and reconciliations in its Management’s Discussion and Analysis. Fortuna attributes quarter-over-quarter changes in profitability and costs to factors such as gold prices, mine stripping ratios, share-based compensation, foreign exchange impacts, and royalties.
The company also highlights its liquidity position and net cash balance, linking these to its ability to fund growth initiatives, including Diamba Sud, Séguéla plant expansion studies, and exploration across West Africa and Latin America. These disclosures provide context for how Fortuna supports its capital programs while maintaining financial flexibility.
Sustainability and energy initiatives
Fortuna repeatedly states that sustainability is at the core of its operations and stakeholder relationships. In its Caylloma mine update, the company reports completion of a power grid enhancement project that allows the mine to meet its current and future energy requirements through the national power grid, which it notes is supplied entirely from renewable sources. This change eliminates the need for supplemental diesel-based power generation at Caylloma.
At Séguéla, Fortuna has disclosed the completion of a third lift of the tailings storage facility, designed to provide storage capacity through early 2030 at current throughput rates, and the decommissioning and construction of public transmission towers to enable pre-mining activities at the Sunbird deposit. The company also reports on-site works for a 6 MW solar power facility at Séguéla, as well as engineering studies for processing plant expansion. These initiatives illustrate how Fortuna integrates infrastructure, energy, and tailings management into its mine development and operation plans.
Corporate actions and capital allocation
Fortuna’s news releases describe several corporate actions that shape its portfolio and capital structure. The company has completed the sale of the San Jose Mine in Mexico and the Yaramoko Mine in Burkina Faso, describing these as non-core or short reserve-life assets, and has reported that consolidated production figures for 2024 and 2025 exclude or separately present these divested operations.
In early 2026, Fortuna reported progress on a normal course issuer bid (NCIB), under which it repurchased and cancelled common shares on the open market of the New York Stock Exchange. The company links its share repurchase activity to its broader capital priorities and notes that it continues to advance its organic growth projects while executing the NCIB.
