Buxton Resources (ASX:BUX) has secured a drilling rig to test a large electromagnetic conductor at its Madman Copper-Gold Project in Western Australia.
The company completed downhole electromagnetic (DHEM) surveying of both diamond drill holes from its maiden program, with final modelling placing the untested off-hole conductor approximately 250m north-northeast of hole MD003DD.
The modelled plate solutions range from 400m by 400m to 1,000m by 1,000m in size, with moderate conductance of around 400 to 1,000 siemens. The target strikes northwest and dips 55–75° southwest, consistent with structural controls from fault-hosted gold intersected in MD002DD.
Managing Director Marty Moloney says: “Completing downhole electromagnetic surveying in both MD002DD and MD003DD has now constrained the off-hole conductor at Madman far more tightly — a large body a few hundred metres north-northeast of the nearest hole MD003DD in a completely untested position.”
Buxton deems the association of gold with pyrrhotite in MD002DD significant due to its high conductivity. The company has therefore flagged the conductor as the highest-priority target at Madman, with its size highlighting the project’s scale potential.
McKay Drilling has confirmed rig availability, with mobilisation scheduled for late September. A planned follow-up hole will be collared at the existing MD003DD drill pad and drilled at -70° toward 015° to a planned depth of 800m.
Buxton expects to intersect the modelled plates between 600–700m down the projected trajectory, with drilling scheduled for completion in October.
The maiden diamond drilling program comprised two holes totalling 1,367m, which intersected quartz-carbonate veining, brecciation, and sulphide mineralisation extending into the basal Skates Hills Formation conglomerate.
Located 375km northeast of Wiluna, the Madman Project targets a Havieron-style magnetic anomaly near the Marloo Fault. The project area is accessible via the Gunbarrel and Eagle highways, as well as along a historic seismic line track.
Buxton notes that assays for MD003DD remain pending and are expected in October. Heritage notices have also been lodged for ground gravity and electromagnetic surveys targeting further anomalies.
Buxton Resources is focused on acquiring, exploring, and developing metalliferous ore deposits, including nickel, copper, gold, iron, and graphite, in Australia and the US.
