Northern Star Resources reports strong exploration results across its Australian hubs, with deep extensions and high‑grade gold intercepts at operations including Kalgoorlie Consolidated Gold Mines in Western Australia. Drilling has identified mineralisation continuing at depth beneath existing workings, with multiple emerging zones that could support life‑of‑mine extensions and higher‑grade feed to existing mills. For mine planners and geotechs, the focus now shifts to underground access design, ground support in deeper stress regimes, and sequencing to integrate new stopes into current production.

Regis Resources is flagging a “significant pipeline” of near-mine and regional exploration targets across its Duketon and Tropicana gold operations in Western Australia, aiming to extend mine life and lift mill feed quality. The company is focusing on brownfields drilling around existing open pits and underground workings, plus greenfields prospects along under-tested shear zones within its Duketon belt and the Tropicana joint venture corridor. For geotechs and mine planners, the message is to expect ongoing resource definition drilling, updated pit shells and potential underground studies rather than major new project footprints.

Harmony Gold has advanced its Eva copper project in Queensland by awarding Metso a major equipment contract as the greenfield mine moves towards site construction. The deal covers key comminution and processing plant components, with Metso to supply crushing and grinding equipment sized for large-scale copper throughput at one of Australia’s biggest planned copper developments. The contract signals design lock-in for the process flowsheet and allows detailed engineering, foundation design and construction scheduling to proceed on a firmer basis.
