MGX Resources is deploying a $412.1 million cash and investment pool to fast‑track the Central Tanami gold project in the Northern Territory, focusing on accelerated drilling, site infrastructure upgrades and underground mine preparations. The 50 per cent‑owned Central Tanami Project Joint Venture is moving towards commencement of the Groundrush underground operation, shifting MGX’s portfolio away from iron ore. For engineers, the spend signals imminent demand for geotechnical design of underground stopes, ground support and dewatering, plus haul road and camp upgrades along the Tanami Road corridor.

Beacon Minerals has more than tripled the Ore Reserve at its Iguana gold deposit in Western Australia to 11 million tonnes at 1.20g/t for 430,200oz, up from 132,200oz, supporting a nine-year mine life. The updated plan is forecast to generate $841 million in undiscounted pre-tax free cash flow, signalling a materially larger open-pit and/or underground schedule and longer commitment to associated waste dumps, tailings capacity and haulage infrastructure. Geotechnical and mine planning teams will need to revisit pit slopes, dewatering and fleet sizing to optimise the expanded reserve.

Meeka Metals has intersected visible gold about 300m below the current Turnberry underground resource in Western Australia’s Murchison region, signalling potential depth extensions to the orebody. Diamond hole 26TBRD010 hit visible gold at 632.8m down-hole within a broad shear zone containing chalcopyrite, pyrite, albite and magnetite, pointing to a sulphide-rich, structurally controlled system. Assays are pending, with results expected in September after detailed core logging, which will guide further deep drilling and resource modelling.
