AuKing pushed a planned 300m diamond hole to 510m after carbonatite kept running at Tundulu. More deep holes are planned before a maiden resource estimate later this year.
AuKing Mining (ASX:AKN) has drilled carbonatite geology continuously through a 510-metre hole at its Tundulu rare earth project in Malawi, with end-of-hole logging showing the system remains open at depth.
The company had planned the first diamond hole to 300 metres but pushed to 510 metres after the carbonatite kept running. MD Paul Williams said the observations from that hole "compelled the drilling to continue well beyond that depth".
More deep diamond holes are now planned to test the depth extension. Results so far have revised the company's view of the overall geological model, which Williams described as "much broader and deeper than first anticipated".
The current drilling program is focused on Nathace Hill, where the company aims to generate enough geological data to support a maiden mineral resource estimate later this year.
AuKing also completed the reverse circulation component of its initial Tundulu program on 31 July 2026, drilling 4,300 metres across 31 holes. Detailed logging confirmed widespread carbonatite lithologies across the entire drilling area. The company flagged particular interest in carbonatite material from drillholes located well away from the primary Nathace Hill target – a sign the mineralised system may extend beyond the historical focus zone.
Williams acknowledged delays in assay results from the early drilling, attributing them to the logistics chain from Malawi through Zambia to a lab in Perth. The samples have now arrived at Intertek's Perth facility, and the company expects a faster turnaround from here.
AKN traded flat at 1.8 cents, with a market cap of A$42 million.
