Desoto Resources Limited (ASX:DES) has provided an exploration update on its activities and assays for its Guinea and Northern Territory Projects. In Guinea, the company has completed 51 RC-holes (totalling 5,743m) at the Dadjan and Tolé Projects, with assays pending. Additionally, 124 Power Auger holes (totalling 2,327m) have been completed at Bofoani (formally NE Tolé), with assays pending, ahead of maiden RC drilling. The company has also completed a trench at Bofoani, with mapping and sampling of structures in and around the trench. At Timbakouna, 857 soil samples and 33 rock samples have been collected, with assays pending. At Komah (formerly Syncerus), 23 BLEG samples have been collected, together with mapping of known artisanal gold mining sites. Maiden work programs are set to commence shortly on the Koba, Nérékoro Sud, Mini and Kassa Est Projects, now that the necessary approvals have been received. This will enable the company to explore to the south of Dadjan and consolidate the Dadjan, Tolé, and Kassa Est Projects. In the Northern Territory, all samples from the 2025 drilling program have been delivered to the lab in Perth, with results expected in the coming weeks. Work programs for the 2025 exploration season have now been completed.
