Brightstar Resources has reported its largest Sandstone result at the Two Mile Hill deposit in WA, intersecting 305m at 2.66g/t gold from 503m depth in diamond hole TMHDD26005. The interval contains multiple high-grade zones, including 4.1m at 26.1g/t, 5.5m at 25.2g/t and 4m at higher-grade material within the broader mineralised envelope. The scale and continuity of this intercept materially upgrade the grade-times-width profile of Two Mile Hill, supporting potential for bulk underground mining scenarios and further deep drilling.

AIC Mines has closed a $70 million acquisition of Materra Metals, securing 100 per cent ownership of the Mt Cuthbert copper project in north‑west Queensland and adding 18.7 million tonnes of copper resources to its portfolio. The company plans a major drilling program in 2027, signalling a shift from resource consolidation to definition drilling and potential mine planning at Mt Cuthbert. For geotechnical and mine planners, the deal points to upcoming demand for pit design, hydrogeology, and infrastructure studies in a historically underdeveloped copper district.

Aureka has signed a binding share sale agreement to acquire 100 per cent of High Grade Holdings, parent of Core Prospecting, pivoting the ASX-listed junior from pure exploration to near-term gold production in Victoria. The deal adds the Fiddlers Creek operation to Aureka’s existing Stawell Corridor, St Arnaud and Jubilee projects, consolidating a regional portfolio along proven high-grade gold structures. For mine planners and geotechs, the move signals a shift towards reactivating historic workings and integrating small-scale production with ongoing resource definition drilling.
