Auric Mining has acquired second-hand crushing and processing infrastructure for $1.2 million, securing key equipment for its planned Burbanks restart at a substantial discount to estimated replacement cost. The package is scheduled to move from New South Wales in late 2026, with installation preparation targeted for early 2027.

AuKing Mining has approved planning for an approximately 1,000-metre diamond hole at its Tundulu Rare Earths Project in Malawi. The hole will test the depth of the carbonatite system at Nathace Hill after strong initial RC results and two deep diamond intersections.

Prominence Energy has secured an independent resource framework for its Eyre Project, with RISC Advisory estimating 202.8 Bscf of 2U unrisked hydrogen and 9.2 Bscf of helium across 15 leads. The milestone moves the South Australian project towards target selection, potential farm-out discussions and a planned mid-2027 drilling campaign, but the volumes remain undiscovered and highly exploratory.

D3 Energy has identified deeper water zones that are now sitting above the gas-bearing intervals in two Nooitgedacht wells, restricting gas flow in an extremely low-pressure reservoir. Remedial cementing is expected to begin next week, but restored flow and commercial results remain unconfirmed.
