Mamba Exploration (ASX:M24) has kicked off a 6000-metre reverse-circulation campaign in Western Australia’s Murchison region, aiming to test three gold-in-soil anomalies along the Mulga Bill trend. The project sits in a remote mining district that has hosted several historic discoveries, making the new work especially noteworthy for investors and geologists alike.
Recent market reaction and historic data review
The company’s share price more than doubled after a September release detailed a review of historic work that logged 165 copper intersections across 47 holes at the Copper Hills and Lady Alma prospects.
At Copper Hills the program recorded 26 metres at 1.0% Cu and 23.1 metres at 1.1% Cu, while Lady Alma returned 13.4 metres at 1.3% Cu, including a 5.2-metre interval grading 2.7% Cu. These intercepts demonstrate a consistent presence of copper mineralisation that could support future mining plans.
The base-metal potential adds weight to the area’s existing gold prospectivity, encouraging the firm to expand its exploration footprint.
New reverse-circulation effort
The current campaign will comprise up to 50 holes and is scheduled to run through to mid-December.
The three targets together span roughly 20 km of strike along the Mulga Bill corridor. This extensive alignment allows the program to test multiple structural controls that could host mineralisation.
In parallel, Mamba is preparing a diamond-work program at Copper Hills and Lady Alma. Government approval has been secured for an initial 2000-metre operation focused on the southern end of Copper Hills, with mobilisation expected early next year.
An additional plan for Lady Alma proposes up to 30 reverse-circulation holes, totalling about 7500 metres of underground work.
Historically, early copper discoveries in the Murchison have often preceded larger gold campaigns, as seen in the nearby Mount Magnet projects where initial base-metal hits triggered multi-year gold-focused programmes.
The first hole of the new campaign is slated to be spudded in early November, marking the start of what the company hopes will be a decisive phase of exploration. Early results from this initial hole are expected to guide subsequent drilling decisions.
Logistics and field operations
Field crews have mobilised to the Mulga Bill corridor, establishing a base camp near the existing road network. Support vehicles and drilling rigs were positioned to access the three target zones efficiently. The team plans to rotate crews to maintain continuous progress through the season, ensuring that each shift can build on the previous day’s findings.
All drilling equipment complies with the regional safety and environmental guidelines set by the Western Australian authorities. Waste management protocols include on-site containment and regular monitoring of water sources.
