Resolute Boosts La Debo Resource by 60 Percent, Strengthening Côte d’Ivoire Growth Pipeline

Resolute Mining has reinforced its growth strategy in Côte d’Ivoire with the announcement of an initial mineral resource estimate of 643,000 ounces of contained gold at the La Debo Project. This figure represents a 60 percent increase over historical assessments and highlights the strategic value of La Debo within Resolute’s expanding West African portfolio. The company’s sustained focus on high impact exploration continues to reveal new opportunities that strengthen its long term development pipeline across the region.

The significant uplift in resources is largely attributed to exploration success at the high grade G3S prospect, which has proven to be the primary driver of the new estimate. The performance of G3S confirms the geological potential of the broader La Debo system and supports Resolute’s plan to allocate further exploration capital into the area. Upcoming drilling will focus on expanding the G3S footprint and testing additional targets in the south western portion of the permit, an area believed to hold further zones of structurally controlled mineralisation. Complementing this momentum, Côte d’Ivoire granted Resolute two new permits, Serihio and Okroyou, in October 2025, with field based exploration scheduled to commence in 2026.

Across its wider Ivorian portfolio, Resolute now controls over 7 million ounces of gold, distributed across three key assets. The Doropo Project remains the company’s most advanced development, with an updated feasibility study expected in December 2025. If results remain positive, construction is planned for 2026, setting the stage for first gold production in 2028. Meanwhile, the ABC Project, which hosts 2.2 million ounces of gold, is progressing through a 25,000 metre reverse circulation drilling program aimed at refining resource models and identifying near mine growth opportunities. These project level advancements align with Resolute’s commitment to aggressive exploration and disciplined value creation for shareholders. Additional exploration and mine extension updates from Senegal are also anticipated before year end, further broadening the company’s regional footprint.

Taken together, these developments signal growing momentum for Côte d’Ivoire’s mining industry. The expanding mineral resource base at La Debo, coupled with advancing feasibility work and large scale drilling campaigns, suggests a rising contribution to the country’s future gold output. For West Africa more broadly, heightened investment from operators like Resolute strengthens the regional supply chain, stimulates service sector activity, and enhances the competitiveness of host economies. If current trends continue, these projects could play a meaningful role in shaping the next phase of mining driven economic growth across the continent.
