Latest Mineral Resource Estimation News

Auric Mining’s Munda Gold Deposit resource estimate has surged 32% to 4.20 million tonnes at 1.43 g/t gold, driven by higher-grade grade control drilling and stronger-than-expected production from the Starter Pit.

Aldoro Resources has achieved a major metallurgical milestone at its Kameelburg project, with direct acid leach tests recovering up to 72% of rare earth elements and over 99% of strontium without prior beneficiation, suggesting a potentially lower-cost development pathway.

Nex Metals Explorations has finalised the sale of its 20% stake in the Yundamindra and Kookynie Gold Joint Venture to Arika Resources, securing $0.5 million in net cash and a significant shareholding. The move clears joint venture funding obligations and redirects capital towards advancing its Kookynie Tailings Project and Egyptian exploration.

Arika Resources has completed its acquisition of 100% ownership of the Yundamindra and Kookynie gold projects, consolidating control over key assets in Western Australia’s Eastern Goldfields and setting the stage for accelerated exploration.

Brazilian Critical Minerals (ASX: BCM) reports robust magnesium sulphate leach results from its 2025 drilling at the Ema project, validating key assumptions for a long-life, low-cost rare earth operation.

Tungsten Mining NL has kicked off a large-scale drilling campaign at its Mt Mulgine Project, aiming to test a substantial exploration target that could significantly boost its tungsten resources.

Lac Gold has reported standout high-grade gold intersections at its Astoria deposit within the Rouyn Gold Project, including a blistering 0.5m intercept grading 1,580g/t Au. These results underpin a structurally complex, large-scale orogenic system and come as Phase 2 drilling ramps up.

Magnum Mining has significantly increased its exploration footprint around the Piracanjuba rare earth clay discovery in Brazil, securing 14 new permits and advancing a major drilling campaign targeting a large-scale deposit.

American West Metals has reported exceptional assay results from resampling historical drill core at its West Desert Project in Utah, revealing high-grade indium, copper, zinc, silver, and lead. The new data expands known mineralised intervals and supports ongoing drilling and government engagement.

Breakthrough Minerals has revealed promising initial assay results from its maiden diamond drilling at the Barbara Copper-Gold Project, highlighting high-grade copper mineralisation and significant resource expansion potential within and beyond current boundaries.

Dart Mining has unveiled robust assay results from diamond drilling at the Banshee prospect, confirming high-grade gold, silver, and antimony mineralisation over a 500m strike. The findings reinforce the potential for resource growth and support plans to increase Dart's stake in the Coonambula project.

Nexus Minerals has reported robust gold assay results from its Wallbrook Gold Project, with the Payns Prospect delivering continuous mineralisation including grades up to 19.00g/t Au. The ongoing drilling program is on track to expand the project's resource base ahead of a September update.
