Latest Economic Studies News

Image Resources has expanded the Mineral Resource at its Durack mineral sands project by 43% to 37.7 million tonnes, while lifting contained heavy minerals and zircon content. The upgraded estimate gives the company a stronger technical base for an economic evaluation due later in 2026, although changes to the cut-off and mineral definitions complicate direct comparisons.

Golden Horse Minerals has expanded the interpreted Hopes Hill gold system beyond 3 kilometres after completing 52,762 metres of drilling in the six months to June 30. The exploration push delivered multiple high-grade intersections and free-milling metallurgy, but came with no revenue, a $4.37 million loss and a sharp drawdown in cash.

OD6 Metals has extended its Rocket-Big Jim-Spar fluorspar corridor at Quinn in Nevada to approximately 700 metres, with six surface samples returning at least 97% CaF₂ and three reaching 99.9%. The results expand the project’s high-grade story, but remain based on selective rock-chip sampling rather than drilling.

Lux Copper has begun its maiden drilling campaign at the 100%-owned Baird Copper Project in Alaska, targeting historical high-grade copper results at Omar and Frost. The first assay results are expected in October, creating a near-term test of the project's exploration potential.

Galileo Mining has lined up two drilling programs at its Norseman project, targeting an untested extension near Callisto and shallow sulphide mineralisation at Mission Sill. The programs will test encouraging but still preliminary exploration indicators, with results yet to come.

Marimaca Copper has reported a 216-metre sulphide intersection grading 0.96% copper and 7.2g/t silver at Pampa Medina, including 62 metres at 2.20% copper and 21.5g/t silver. Step-out drilling also extended mineralised horizons beyond the central zone, while diamond drilling is now testing deeper ground to the north and northwest.

DPM Metals has extended mineralization beyond the existing Dumitru Potok resource in Serbia, led by a 21-metre interval grading 5.44% copper equivalent. The company will add up to 15,000 metres to its 2026 drilling campaign as it works towards a resource update and preliminary economic assessment.

Great Divide Mining has consolidated and restated a high-grade gold resource at its Adelong Project, confirming 169,700 ounces of contained gold with over half classified as Measured or Indicated.

Andean Silver has raised A$40 million through a discounted placement to accelerate production restart plans and resource growth at its Cerro Bayo silver-gold project in Chile, underpinning its push toward feasibility studies and early works.

Desert Minerals has delivered a maiden JORC Mineral Resource Estimate for its Scotty Lithium Project in Nevada, outlining a substantial lithium clay deposit of 264.9 million tonnes at 1,006 ppm lithium, alongside a sizeable Exploration Target that hints at further growth.

Western Gold Resources has lifted the Gold Duke Project’s Mineral Resource to 277,000 ounces of gold, marking a 29% increase in contained gold and a significant jump in resource confidence following extensive drilling.

Many Peaks Minerals has reported strong reverse circulation drilling results at its Ouarigue prospect in Côte d’Ivoire, confirming continuity and extensions of gold mineralisation over 800 metres of strike. The results bolster prospects for upgrading the resource and expanding its footprint ahead of a planned fourth-quarter Mineral Resource Estimate update.
