New Gold Zones at Tole and Dadjan Raise Stakes Ahead of Drilling

Exploration Momentum Builds at Tole and Dadjan

DeSoto Resources Limited (ASX, DES) has announced encouraging exploration results from its gold projects in Guinea’s prolific Siguiri Basin. Recent soil sampling at the Tole and Dadjan projects has delineated new zones of gold anomalism, providing fresh targets for the company’s imminent maiden drilling programs.

At the Tole Gold Project, a newly identified 2.3-kilometre-long zone of coherent gold-in-soil anomalies at the northeast section of the tenement stands out as a significant discovery. This zone confirms continuity of mineralisation previously suggested by rock chip and dump sampling, with soil assays revealing gold concentrations exceeding 1,000 parts per billion (ppb) in one sample, and several others ranging between 200 and 575 ppb. These results highlight the prospectivity of the area and underpin plans for reverse circulation (RC) drilling following ongoing trenching activities.

Dadjan Project Shows New Prospective Zones

Similarly, the Dadjan Gold Project has yielded promising soil assay results, particularly in the southwestern portion of the tenement, where gold values reached up to 923 ppb. The sampling program has also identified new anomalous zones to the north and south of the Dadjan Main Zone prospect, expanding the footprint of potential mineralisation. The company is continuing soil sampling on a detailed grid and has completed two trenches, with further trenching underway to better understand the subsurface geology ahead of drilling.

Strategic Positioning in the Siguiri Basin

DeSoto’s exploration efforts extend beyond Tole and Dadjan, covering a substantial 934 square kilometre landholding across multiple projects including Moiko, Alamankono, Oromo, Falama, and Dabidiana. The Siguiri Basin is known for its Birimian-aged rocks and orogenic gold mineralisation, typically associated with structural corridors near felsic intrusives. The company’s systematic approach; combining soil sampling, trenching, and planned drilling; aims to unlock the basin’s potential and advance these projects toward resource definition.

Importantly, the soil sampling methodology and assay procedures adhere to industry standards, with quality control measures such as field duplicates and laboratory repeats ensuring data reliability. While the true widths of mineralised zones remain to be determined through drilling, the current results provide a robust foundation for the next phase of exploration.

Looking Ahead

With maiden RC drilling programs on the horizon, DeSoto Resources is poised to test these newly defined gold zones and potentially convert surface anomalies into mineral resources. The company’s ongoing trenching and sampling will continue to refine drill targets, while exploration across its broader portfolio maintains momentum in one of West Africa’s most prospective gold regions.
