DeSoto Resources Limited reveals promising gold assay results from its Guinea projects. Early-stage drilling and trenching at Dadjan and Tole confirm high-grade, near-surface mineralisation across its vast Siguiri Basin portfolio, sparking investor interest in potential large-scale discoveries.
DeSoto Resources Limited has released an extensive update on its Guinea exploration campaign, highlighting promising early-stage results across several projects in the Siguiri Basin. The announcement details the outcomes of a shallow power auger infill program at the Dadjan Project, where assay results from 56 holes over 1,026 meters of drilling have returned significant gold values, including a notable intercept of 10 meters at 1.61 g/t gold and grades as high as 5.73 g/t. These findings confirm the presence of a substantial gold-bearing zone near the surface that extends to at least 20 meters depth, with mineralisation remaining open to the north, prompting a detailed soil sampling grid and the commencement of trenching to further delineate the high-grade zones.
The update also outlines ongoing exploration activities at the Tole Project, where a 100 x 50 meter soil sampling program is underway around a northeast gold anomaly that previously returned an 8-meter intercept at 18 g/t gold. Detailed surface sampling, including rock chip and dump sampling of artisanal workings, is planned to better define the mineralised zones. Additional regional efforts are being pursued at the Moiko/Alamankono, Falama, Oromo, and Dabidiana Projects, with systematic reconnaissance mapping, stream sediment sampling (with BLEG analyses in progress), and further surface programs designed to capitalize on the company’s extensive land holdings across a 934 km² area in the Siguiri Basin.
Methodologically, the company is applying a mineral systems approach that has historically led to significant discoveries in West Africa. The strategy involves first-pass screening techniques—such as systematic soil and rock chip sampling—followed by targeted power auger drilling to penetrate the lateritic cover and access saprolite derived from bedrock sources. This multi-tiered program aims to provide early indications of deposit sizes, with the company using its benchmark of a two-million-ounce gold deposit for success evaluation before advancing to more intensive drilling methods.
Market sentiment appears mixed. On the bullish side, the impressive grades and continuous near-surface mineralisation at Dadjan, along with corroborative high-grade indicators at Tole, signal positive exploration momentum and underpin the company’s extensive portfolio in a region ripe for tenure growth, bolstered by recent government reforms. However, on the bearish side, these are early-stage exploration results that require further drilling and in-depth geological interpretation to confirm true widths, deposit continuity, and commercial viability. Investors should be aware that while the technical results are encouraging, inherent risks remain as the projects progressively move towards more advanced stages of exploration.
