DeSoto Resources Enhances Copper Prospects with New Gravity Data

Survey Completion and Initial Findings

DeSoto Resources Limited has successfully completed ground gravity surveys at its Spectrum and Fenton South projects. The surveys, conducted by Atlas Geophysics, covered a high-resolution 500m x 125m grid. Preliminary assessment and modeling of the newly acquired gravity data have upgraded and refined targets at both project areas.

The gravity data indicates a strong gravity gradient associated with the Fenton Shear Zone (FSZ), confirming that the Quantum, Vesper, and Fenton South targets are all situated along this zone. These targets are also coincident with zones of NE-SW striking cross faulting, enhancing their prospectivity for copper-gold mineralization.

Emerging Copper Story at Spectrum

At the Spectrum project, the gravity survey has mapped the northern continuation of the FSZ, which truncates and may locally control rare earth element (REE) and gold mineralization at the Quantum target. This structure is interpreted to have at least 8 kilometers of prospective strike coincident with MMI copper soil anomalies. This trend remains largely untested by previous drilling and is considered highly prospective for Mary Kathleen style copper-REE and similar high-grade copper skarn-style mineralization.

At the Vesper target, gravity survey data shows two moderate amplitude residual anomalies coincident with modeled Airborne Electromagnetic (AEM) conductor plates and strong MMI copper anomalies in an area of structural complexity.

Fenton South Geophysical Surveys

At Fenton South, Zonge has completed three loops of the ground Fixed Loop Electromagnetic (FLEM) survey. The gravity data indicates a 1mgal residual gravity anomaly coincident with the Fenton South AEM anomaly, slightly offset from a moderate intensity magnetic anomaly that potentially defines the core of a fold. The eastern margin of the Fenton South gravity anomaly is bounded by a strong gravity gradient, interpreted to be correlated to the mineralized FSZ.

The coincident gravity and AEM anomalies at Fenton South present an outstanding untested drill target for DeSoto's upcoming drill campaign. The company has also been awarded a $160,000 Resourcing the Territory Grant for Fenton South, with details of the drilling program to be announced upon completion and collation of the new ground geophysical data.

Next Steps

DeSoto Resources plans to continue its exploration efforts with ongoing ground FLEM surveys at the Quantum and Vesper targets, followed by ground Induced Polarisation (IP) surveys. At Fenton South, the company is planning an MMI soil geochemical survey to further generate and refine existing targets and assist with geological interpretations. IP surveys will also be collected to further refine conductor targets generated from the FLEM surveys and to assist with geological interpretations. Drill permitting is underway with approvals expected in August, pending finalization of the NT Government's new drilling permitting process.
