Latest Diamond Drilling News

Historical work has identified widespread near-surface columbo-tantalite mineralisation at Australasian Metals’ Atex project in Côte d’Ivoire, adding a potential tantalum stream to its lithium strategy. The results are encouraging, but the underlying estimate is non-JORC, unverified and based on incomplete historical records.

Narryer Metals is buying the Redhill Copper Project in southern Chile from 29Metals, gaining an existing 4.3Mt inferred resource and a much larger conceptual exploration target. The deal also brings a A$1 million strategic investment from 29Metals at a 54% premium to Narryer’s pre-announcement share price.

Five of nine diamond holes at Minrex's Barje deposit have returned the widest and highest-grade intersections drilled there, challenging the historical model of a low-grade central corridor. The results arrive ahead of a maiden JORC resource estimate planned for next quarter.

Magnum Mining has completed a 10,000-metre auger programme at its Piracanjuba North ionic adsorption clay rare earths project in Brazil, shifting its focus to a 32.5km² plateau zone. The company is targeting a maiden JORC 2012 Mineral Resource Estimate in November, but the project remains at an early exploration stage with no declared resource or reserve.

Cannindah Resources has reported preliminary NovaCell testwork recovering 94% of copper and 92% of silver at a substantially coarser grind, while rejecting 82% of processed material. The results could support a higher-throughput, lower-energy processing route, although gold recovery and concentrate quality still require further work.

Anax Metals has moved its Whim Creek copper-zinc project closer to a targeted investment decision, backed by strong feasibility economics and new drilling. But the annual report makes clear that development still depends on securing further funding, with the auditor warning of a material uncertainty over going concern.

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.

North Stawell Minerals has extended a steep west-dipping gold-bearing structure at Darlington with a 0.5-metre intercept, though the latest grade is well below nearby high-grade results. The company says the trend remains open at depth and along strike, with further drilling needed to test its potential scale.

Argent Minerals has reported its first laboratory assays from Trunkey Creek, with narrow but high-grade gold intersections beyond a void interpreted as historic underground workings. The results strengthen the case for deeper drilling, while leaving the size and continuity of the mineralisation unresolved.

Saturn Metals has extended the Apollo Hill gold system up to 1km north of its existing 2.83Moz Mineral Resource, with several high-grade intersections among the latest results. A 50-hole, 10,000m RC program is now underway to test continuity and support a planned resource update.

Killi Resources has intersected a 50-metre zone of visually estimated crystalline magnetite 600 metres south of Lodestone’s existing 110Mt inferred resource. The result also identified a separate 16-metre hanging-wall zone, but assays and metallurgical testing are still pending.

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.
