Latest Air Core Drilling News

Powerhaus Uranium has moved from ASX debut to field execution, preparing a 4,000-5,000 metre drilling campaign at its Malbec project in Argentina. The explorer ended September with A$7.958 million in cash, but its first field survey produced no significant surface radiometric response and assays are still pending.

Dart Mining has begun its first deep drilling campaign at the Walwa tin project while advancing a new Western Australian landholding and a Coonambula resource estimate. The exploration pipeline is expanding, but the company ended September with $273,000 in cash and is relying on a $1.37 million capital-raising tranche subject to shareholder approval.

Cullen Resources has extended shallow gold-silver-copper targets at Yardilla and identified a new conductor for drilling at North Tuckabianna. But with $176,000 in cash and an estimated 0.81 quarters of funding, the next exploration steps will likely depend on new financing or asset sales.

Ordell Minerals has reported broad, shallow gold intersections at McNabs East, with the results expected to support a maiden Mineral Resource Estimate in the December 2026 quarter. Deeper drilling is also extending mineralisation, while the company advances technical work on a potential Barimaia development opportunity.

Many Peaks Minerals has extended the tested depth of its Ouarigue gold system beyond 900 metres, with a post-quarter hole returning 188.9 metres at 3.58g/t gold. The results will feed an updated resource estimate and a combined open-pit and underground assessment, while the company’s A$20.1 million cash balance supports the next phase of work.

Antipa Minerals has returned a 22-metre gold interval grading 8.2 grams per tonne at its Minyari deposit, including 5.1 metres at 27.4 grams per tonne. The latest assays also extend mineralisation at GEO-01, WACA, Rizzo, Tim’s Dome and Chicken Ranch as drilling continues across the project.

Yandal Resources has extended its high-grade Arrakis discovery with a 20-metre intercept at 8.7g/t gold, including 3 metres at 52.8g/t. The exploration momentum comes with a pressing funding requirement, as the company ended September with $3.29 million in cash and plans an equity raising during the December quarter.

Rimfire Pacific Mining’s latest Murga tests continue to show atmospheric scandium recovery, while a $2.3 million placement funds drilling and technical work across its NSW portfolio. The results remain early-stage, with projected long-term recoveries based on extrapolation rather than completed testing.

Lincoln Minerals says air core drilling has confirmed that mineralisation at Eagle Ridge continues up dip, strengthening the case for a targeted diamond drilling program at Minbrie in the December quarter. The explorer ended September with A$3.085 million in cash after receiving A$2.1 million from equity issues.

Antipa Minerals has selected a gold-and-copper processing pathway for its Minyari Dome project, bringing the pre-feasibility study closer to release in November. At the same time, drilling expanded Tim's Dome mineralisation across 2.2km, while quarterly exploration spending reduced cash to A$28.0 million.

Xpedra Resources has completed its first 31 Springfield RC holes with broad gold mineralisation now traced across 400 metres of strike and open at depth and along strike. A larger 4,000 to 5,000 metre drilling campaign is due to begin shortly, while the company has added the historic Neeld Gold Project to its NSW portfolio.

Galileo Mining has expanded its near-term exploration pipeline at Norseman, with mineralised outcrop north of Callisto, two kilometre-scale PGM target zones at Mission Sill and a new gold prospect. The company ended September with approximately A$6.9 million in cash, funding aircore and RC programs already under way or scheduled.
