9km-Long Active Gold Zone at Koba with Exploration Underway

• Initial reconnaissance at Koba has identified a large and active artisanal mining zone, approximately 9km-long and up to 1km-wide
• Dump sampling has returned gold grades up to 15.2g/t Au
• Soil sampling programs have been completed with results pending

DeSoto Resources has commenced exploration at its Koba Project, located in the south-central Siguiri Basin in north-eastern Guinea. Initial reconnaissance at Koba has identified a large and active artisanal mining zone, approximately 9km-long and up to 1km-wide. Dump sampling from this zone has returned gold grades of up to 15.2g/t Au. Given the size and scale of the artisanal mining activity, the company has completed initial soil sampling programs with results pending. The Koba Project is situated between the 4Moz Tri-K Deposit (Managem) and the 7.73Moz Bankan-Kiniero deposits (PDI/RXR Merge Co), and was initially prioritized within a target corridor identified by the company's Chairman and Non-Executive Director. The company's systematic exploration approach integrates regolith and artisanal mapping, BLEG stream sediment sampling, soil geochemistry, geophysics and follow-up drilling, with the objective of delineating large-scale gold systems comparable to those already defined elsewhere within the Siguiri Basin.

Further soil sampling lines (200m x 800m) have been added south of the active zone as new sites are identified and mapped. Infill soil sampling (200m x 200m) will be completed to vector zones of gold continuity. Upon receiving soil sampling results, airborne geophysics, trenching and power auger drill programs will be completed ahead of maiden drilling programs.
