Unity Metals has identified multiple new gold-anomalous zones across 1,063 metres of trenching at its Ngot and O’Phlay projects in Cambodia. The work also showed that drilling at Ngot NE was poorly oriented to intersect the interpreted mineralisation, setting up a revised drilling campaign.

Dart Mining has confirmed high-grade tin in four selective rock-chip samples from its Walwa project in Northeast Victoria, including 3.96% tin with elevated tantalum and niobium. The results strengthen the case for maiden diamond drilling planned for October, but do not establish representative grades or a mineral resource.

Pantoro Gold has extended the interpreted mineralised strike at its Racetrack discovery to about 900 metres, with drilling returning several high-grade intersections. The company will begin a 450-metre exploration decline from the OK Underground Mine in the December 2026 quarter, although Racetrack remains outside the current Mineral Resource and Ore Reserve.

Tungsten Mining has produced saleable tungsten concentrate grading up to 65.9% WO3 from its Watershed project in Queensland, confirming the conventional processing route planned for its DFS. Marketing samples have now been sent to potential offtakers, although no binding agreements have been signed.

Cannindah Resources is accelerating drilling at its Cannindah Breccia deposit after identifying mineralisation beyond the existing resource and along a broader 2km structural corridor. An updated resource estimate, incorporating 45 additional drill holes and new metallurgical inputs, is targeted by the end of September.

Terrain Minerals has recorded gold recoveries of up to 93.7% from first-pass metallurgical testing at its Lightning Gold Project, using a conventional gravity and carbon-in-leach flowsheet. The results reduce a key technical uncertainty, although the work remains preliminary and is based on only three RC chip composites.

Reward Minerals has secured approval for the first-ever drilling at its Jackpot gold-copper prospect in Newfoundland, with a seven-hole campaign expected to begin within days. New soil results have also extended the exploration story across a 1.2-kilometre corridor, including a 378ppb gold anomaly at High Stakes.

FMR Resources has shifted decisively towards Chile, expanding its copper-gold portfolio while early Llahuin drilling suggests the interpreted porphyry core remains untested. The exploration push came with a $6.44 million loss, $4.65 million in cash and a renewed dependence on future capital.

Resolution Minerals has reported its strongest gold grades to date at Golden Gate South, including 1 metre at 14.8 g/t gold, while extending the identified mineralised zone to approximately 600 metres. The results point to possible higher-grade feeder zones, but true widths and the broader continuity of the system remain unconfirmed.

Pursuit Minerals has secured environmental approvals to relocate its pilot plant to Rio Grande Sur and drill a new 500-metre hole at Demasía. The company has also applied to build commercial-scale evaporation ponds for its planned 5,000-tonne-per-year operation, although that approval remains outstanding.

Argent Minerals has intersected visible gold in two apparently unmined quartz veins beneath historic workings during the second hole of its maiden Trunkey Creek drilling program. The encouraging visual result remains unquantified until photon assay results establish the grades and true widths.

Astral Resources has reported broad and high-grade gold intersections from two deep holes at Theia, including 22 metres at 2.73g/t and 2 metres at 12.8g/t. The results extend the evidence for mineralisation below the current resource shell, but any resource increase remains dependent on the six remaining holes and further interpretation.
