Latest Reverse Circulation Drilling News

AusQuest has materially expanded its Cangallo copper-gold discovery in Peru, but the exploration push came with a larger loss, a sharp rise in cash outflows and an auditor warning that further funding is likely within 12 months. The company ended FY2026 with $6.35 million in cash after a $10 million placement.

Nexus Minerals has secured firm commitments for a A$5.4 million placement to fund drilling and exploration across its Wallbrook Gold Project and NSW Mineral Project. The raise is priced below recent market benchmarks and is expected to lift cash above A$8.7 million before costs.

Metal Hawk has secured $1.2 million from sophisticated investors as RC drilling begins at the Numbat lode in Western Australia. The campaign will test whether the company’s strongest Leinster South gold intercept extends along strike and at depth.

Mamba Exploration has confirmed 165 historical copper intersections across a 3km corridor at its 70%-owned Meeka East project, supporting a new felsic volcanic exploration model. The company plans further mapping, geophysics and drilling, although the historical data is not sufficient to define a mineral resource.

Bayan Mining and Minerals has begun a third phase of surface sampling at its Bayan Springs South gold project in Nevada, extending an open southern anomaly and testing a previously unsampled northern fault intersection. The work is intended to sharpen drill targets, while assays from the company’s completed Desert Star RC program are expected in October 2026.

CGN Resources has expanded its exploration footprint across gold and copper, but the annual report pairs that growth with a material going-concern uncertainty. The company ended FY2026 with $2.11 million in cash against $1.99 million of operating cash outflows.

Bellavista Resources is advancing a 15,000-metre drilling campaign and early development studies at Pickle Crow, while assay results have been pushed into October after Canadian laboratory delays. At Brumby, continuity drilling is complete and CSIRO column leach testwork is being prepared.

Parabellum Resources has established a maiden 4.8 million tonne Mineral Resource Estimate at its Miandetta prospect in central NSW, containing 37,000 tonnes of nickel and 1,920 tonnes of cobalt. The shallow resource is a meaningful exploration milestone, but remains preliminary and relies on several conceptual assumptions.

Antipa Minerals has expanded its Minyari Project resource to 3.6 million ounces of gold equivalent and advanced key pre-feasibility work, including conventional processing and deeper open-pit studies. The progress comes with an auditor-highlighted going-concern uncertainty as the company prepares for further exploration and development spending.

Nexus Minerals has more than doubled the Wallbrook Gold Project’s Mineral Resource to 631,000oz, adding maiden resources at Payns and Branches. Combined with Pinnacles, group resources now stand at 709,000oz, although most Wallbrook ounces remain Inferred and no Ore Reserve has been defined.

CZR Resources has expanded its exploration case at Croydon, with shallow gold at Frank’s Patch and Baskerville complemented by deeper mineralisation at Top Camp. The company has also lodged a mining lease application for its Buddadoo vanadium-titanium-magnetite project.

Mt Malcolm Mines has identified four copper-gold exploration targets across its Malcolm Project, led by selective Braiser rock chips grading up to 1.37% copper. The broader target inventory is promising but remains early-stage, with no new drilling completed and most geochemical signals still awaiting laboratory verification.
