Exploration
Fortuna maintains a robust pipeline of early exploration (Greenfield) and near-mine (Brownfield) exploration assets. Our strategy is to continue adding to the longevity of our mines through brownfield exploration while at the same time seeking out additional greenfield projects that will benefit the Company.

Acquired3 in September 2023, the Diamba Sud Gold Project is located in the highly prospective Kenieba-Koudougou Inlier (KKI) which hosts several world class gold deposits in eastern Senegal and western Mali. The results of the PEA were announced on October 15, 2025, and supports robust project economics for the development of an open-pit mine and conventional carbon-in-leach (CIL) processing plant2. The Company is advancing early works toward a mid-2026 construction decision1.

Maps and sections
Tongon Nth – Regional Exploration (emerging)
Located in northern Côte d’Ivoire, Fortuna entered into an option agreement with Turaco Gold to explore the 1,180 kilometers2 Tongon Nth prospect. Covering several highly prospective shear zones within the Senoufo greenstone belt that also hosts the nearby Barrick Gold Tongon Mine, and Lilium Mines’ Wahgnion Mine complex 25 kilometers north in Burkina Faso. Historical exploration has defined several large-scale gold anomalies in prospective geological which are yet to be tested.
Séguéla Regional – Regional Exploration (pipeline)
The Séguéla Gold Mine supports an active and extensive exploration program which has delivered several discoveries since 2019. With a focus on generating new anomalies as well as expanding emerging underground opportunities associated with the high-grade open pits Koula, Sunbird and Ancien, much of the 620 kilometers2 property remains untested.
Guiglo – Regional Exploration (pipeline)
Located in the southwest of Côte d’Ivoire, Fortuna is actively exploring a new Greenfields area which has no previously recorded exploration of artisanal activity, generating several large scale geochemical anomalies within the 772-square-kilometer property.
Cecilia – Regional Exploration (emerging)
Located in northern Sonora, exploration activities will initially focus on mapping and regional reconnaissance before deep drill testing to follow up on shallow historic drilling which intersected widespread gold anomalism associated with silicified breccias and veins in the upper part of a large scale dome complex.
Lindero – Regional Exploration (pipeline)
Located 3 kilometers from Lindero, the Arizaro project is a similar gold-porphyry system and represents upside opportunity that could supplement the Lindero operation. Arizaro remains open to the south-west and at depth, with future exploration to be phased with the long-term mine plans for Lindero.
Caylloma – Regional exploration (emerging)
With a mining history of over 500 years, the Caylloma district is considered a fertile exploration district. Comprising numerous low to intermediate sulfidation epithermal vein systems, Fortuna maintains an active exploration program to test historic workings at depth as well as identifying new, untested targets across the district.
Caylloma – Animas extensions (pipeline)
The Animas system extends for at least 4 kilometers along strike and hosts the active mining for Caylloma. Exploration has continued to replace reserves through targeted drilling at depth and along strike where the Animas vein remains open.
