Sunstone Metals has delivered a robust Scoping Study for its Bramaderos Gold-Copper Project in Ecuador, outlining a 23-year mine life, strong production rates, and a post-tax NPV of US$0.9 billion at a conservative gold price. The study highlights low operating costs and substantial exploration upside, setting the stage for a pre-feasibility study and funding pursuits.

Star Minerals has delivered promising new assay results from extensional drilling at its Tumblegum South Gold Project, revealing shallow, high-grade gold mineralisation beyond the current pit design. The findings underpin plans to update the resource and mine plan, reinforcing the project’s robust economics amid strong gold prices.

Aldoro Resources has reported a 354.2-meter continuous intercept of rare earth elements and strontium at its Kameelburg project, confirming significant northwest extension of mineralisation and reinforcing the deposit's growing scale.

Aurum Resources has unveiled robust assay results from 40 diamond drill holes at the BDT2 deposit, confirming substantial gold mineralisation beyond current resource boundaries and underpinning its 4.2Moz group resource growth strategy in Côte d'Ivoire.

Astral Resources has boosted its Mandilla Gold Project Mineral Resource Estimate by 22% to 1.74 million ounces, introducing a maiden Measured Resource for the flagship Theia deposit. Including Feysville and Spargoville, the Group’s total resource now stands at 2.07 million ounces.

Kalgoorlie Gold Mining has launched a substantial 41-hole reverse circulation drilling campaign at its Pinjin Gold Project, targeting resource growth at Kirgella Gift, Providence, and Lighthorse.
