Bayan Mining has secured U.S. Bureau of Land Management approval for an expanded drilling program at its Desert Star rare earth project, enabling deeper exploration of high-grade targets near the Mountain Pass mine.

FMR Resources has intersected multiple broad mineralised porphyry phases with visible copper and molybdenite at Target K within its Llahuin Project JV in Chile, refining the search for the core mineralised source.

FMR Resources has extended its second diamond drillhole at the Southern Porphyry target within the Llahuin Project JV in Chile, uncovering visual copper and molybdenite mineralisation linked to a key geophysical anomaly. This advancement sharpens the focus on the core of a significant porphyry system.

Yari Minerals has announced a maiden JORC Indicated Coal Resource of approximately 33.7 million tonnes at its Rolleston South Coal Project, boosting the total coal resource by 17% to around 223 million tonnes. The discovery of shallow coal seams and ongoing quality testing highlight the project's growing potential.

Yari Minerals has kicked off its inaugural drilling at the Rolleston South Coal Project, confirming thick, continuous coal seams and promising coal quality that could upgrade its resource status.

Terra Metals reports promising assay results from the Southwest SW1 Prospect, revealing multiple near-surface Bushveld-style reef layers and a newly identified magmatic sulfide zone, expanding the polymetallic footprint of the Dante Project.

Yari Minerals has completed four drillholes at its Rolleston South Coal Project, confirming thick, continuous coal seams and progressing towards upgrading part of its 190.1 Mt Inferred Resource to Indicated status.

FMR Resources has completed its first deep drillhole at the Southern Porphyry target within the Llahuin Project JV, revealing geological features indicative of a large porphyry copper system. Ongoing analyses and geophysical surveys aim to refine the understanding of this promising discovery.

FMR Resources has completed its first deep drillhole at the Southern Porphyry target in Chile, revealing geological evidence of a large, vertically extensive porphyry copper system beneath epithermal mineralisation. Further geophysical and geochemical work is underway to refine the system's potential.

African Gold Limited reports significant resource growth at its Blaffo Guetto deposit in Côte d’Ivoire, with new drilling and metallurgical tests confirming a robust, continuous gold system. The company is well-funded to advance development studies targeting a resource update in early 2026.

Critical Resources Limited reports significant exploration breakthroughs at its Halls Peak Project in NSW, identifying over 30 new antimony-gold targets and confirming high-grade mineralisation at Mayview. Concurrently, lithium drilling at Mavis Lake in Canada delivers promising results, supported by a partial $1.1 million capital raise.

Critical Resources Limited reports encouraging petrographic results from its Mayview Prospect in NSW, revealing a structurally controlled antimony-gold system akin to the nearby Hillgrove deposit. These findings bolster the prospect's exploration appeal with plans for detailed follow-up work.
