Exploration at Koba Faces Uncertainty as Soil and Drilling Results Awaited
DeSoto Resources has identified a substantial 9km-long artisanal gold mining zone at its Koba Project in Guinea’s Siguiri Basin, with high-grade samples up to 15.2g/t Au and ongoing exploration activities underway.
- Discovery of a 9km-long active artisanal gold mining zone at Koba
- High-grade dump samples reaching 15.2g/t gold
- Initial soil sampling completed, results pending
- Strategic location near major gold deposits in the Siguiri Basin
- Planned follow-up includes geophysics, trenching, and maiden drilling
A Significant New Gold Frontier Emerges at Koba
DeSoto Resources Limited (ASX:DES) has announced a promising development at its Koba Project, located in the south-central part of Guinea’s prolific Siguiri Basin. The company has uncovered a large, active artisanal gold mining zone stretching approximately 9 kilometres in length and up to 1 kilometre wide. This discovery is notable not only for its scale but also for the high-grade gold values obtained from initial dump sampling, which reached up to 15.2 grams per tonne.
Strategic Positioning in a Gold-Rich Corridor
Koba’s location is particularly strategic, nestled between the 4 million-ounce Tri-K Deposit operated by Managem Group and the combined 7.73 million-ounce Bankan-Kiniero deposits controlled by Predictive Discovery Limited and Robex Resources. This corridor has long been recognised for its significant gold endowment, and DeSoto’s identification of a large artisanal mining zone here suggests untapped potential for a sizeable gold system.
Systematic Exploration Underway
Following the initial reconnaissance, DeSoto has completed soil sampling programs to assist in vectoring drill targets, with results still awaited. The company is expanding soil sampling lines to the south of the active zone to explore the permit’s full potential. The exploration approach integrates multiple techniques including regolith and artisanal mapping, stream sediment sampling (BLEG), soil geochemistry, geophysics, and planned drilling campaigns. This methodical strategy aims to delineate large-scale orogenic gold systems akin to those already established within the basin.
Next Steps and Broader Regional Context
DeSoto’s immediate plans include infill soil sampling to better define gold continuity, followed by airborne geophysical surveys, trenching, and power auger drilling. These steps will pave the way for maiden drilling programs designed to test the subsurface extent of mineralisation. The Koba Project forms part of a broader south-central Siguiri portfolio that includes Dadjan, Tolé, Nerekore South, Kassa Est, and Mini, all underpinned by a regional BLEG sampling program with results pending.
A Promising Chapter in Guinea’s Gold Exploration
With no prior modern exploration at Koba, DeSoto’s discovery and systematic follow-up work highlight the project’s potential to host significant gold mineralisation. The presence of an extensive artisanal mining zone indicates both the geological favourability and local knowledge of gold occurrences. As the company advances its exploration programs, the market will be watching closely for soil assay results and the outcomes of upcoming geophysical and drilling campaigns.
Bottom Line?
DeSoto’s Koba Project is shaping up as a compelling new gold exploration frontier, with upcoming data releases set to clarify its true potential.
Questions in the middle?
- What will the pending soil sampling and geophysical survey results reveal about the extent of gold mineralisation?
- How will maiden drilling results correlate with the high-grade artisanal mining zones identified on surface?
- Could Koba’s mineralisation rival or complement the nearby multi-million-ounce deposits in the Siguiri Basin?
