Viking Mines has reported high-grade tungsten mineralisation up to 2.7% WO3 at its Long and Terrell Projects in Nevada, expanding the potential of its tungsten portfolio beyond the flagship Linka Project.

Greenvale Energy has identified a substantial 9km-long paleochannel uranium target at its Thunderball Project in the Northern Territory, setting the stage for maiden drilling and further geophysical surveys.

Mammoth Minerals has intersected a fresh high-grade gold zone over 700 metres from its historic Buster Gold Mine in Nevada, expanding the Excelsior Project's mineral footprint. Concurrent surface sampling at the Blue Dick Prospect confirms extensive silver and gold mineralisation, underpinning a robust drilling campaign across multiple targets.

Perpetual Resources has digitised and reviewed 42 historical drill holes from its Nevada Scheelite tungsten project, identifying 22 with significant tungsten grades, underpinning plans for modern validation and 3D geological modelling.

PhosCo Ltd’s maiden drilling at the KH prospect within its Gasaat Phosphate Project in Tunisia has delivered wide, high-grade phosphate intersections close to the proposed plant, promising to enhance early project economics.

Nelson Resources has completed a comprehensive soil sampling program at its Cinnamon Property in Nevada, affirming a high-grade copper-gold discovery at Sheba and prioritising the near-surface tungsten potential at Ophir.

Cassius Mining has secured $2.025 million through a well-supported placement at a 16.67% discount, aiming to fund its Soalara Limestone Project in Madagascar and ongoing arbitration against Ghana.

Estrella Resources has identified multiple high-conductivity anomalies at its Ira Miri project via a novel UAV geophysical survey, prompting plans for the deepest mineral exploration drilling ever in Timor-Leste starting September 2026.

Mammoth Minerals has confirmed significant shallow gold mineralisation extending 700 metres along the Buster trend at its Excelsior Gold-Silver Project in Nevada, signalling potential for a larger Carlin-type gold system. Drilling has now shifted to the high-grade Blue Dick Silver Prospect with results expected soon.

Gold Hydrogen has successfully flowed, purified, and bottled helium at its Ramsay 1 well, confirming a highly productive reservoir and advancing the project towards commercial viability with promising helium rates and purity.

Nelson Resources has identified a promising copper-gold target at its Cinnamon Property in Nevada, delivering rock-chip samples with significant grades and outlining a clear path for advancing both copper-gold and tungsten prospects.

GreenX Metals has outlined a substantial Exploration Target at its Tannenberg Copper Project in Germany, confirming its geological similarity to major Polish Kupferschiefer mines and setting the stage for active drilling and metallurgical work. Concurrently, fieldwork at the Eleonore North Project in Greenland has identified new high-priority tungsten and antimony targets, while a key legal challenge in Singapore was dismissed, affirming GreenX’s compensation rights.
