Latest Diamond Drilling News

Estrella Resources has expanded its Timor-Leste exploration footprint by 100km2 while securing conditional approval to export a 100-tonne manganese sample to an Indonesian customer. The company is also preparing 3,000 metres of drilling and a possible upgrade to part of its 621Mt Werumata limestone resource.

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.

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.

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.

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.

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.

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.

Gold Mountain has returned thick, shallow rare earth intersections at Capivara, including 8 metres at 1,513 ppm TREO, while several auger holes ended near mineralisation. The company now plans deeper drilling to determine whether the strongest results continue through the saprolite profile.

Metal Hawk is restarting drilling at the Numbat lode after its best Leinster South result to date, with up to 10 RC holes planned and diamond drilling scheduled for November. The deeper campaign will be supported by up to $175,000 in Western Australian Government co-funding.

NewPeak Metals will begin a minimum 1,000-metre Phase 2 diamond drilling program at Las Opeñas in Argentina in mid-October, targeting a potentially gold-richer zone west of its recent long intercepts. The campaign is funded from the company’s completed placement, but the higher-grade western extension remains untested.

Broken Hill Gold has started a 48 line-kilometre induced polarisation survey and 670 line-kilometre magnetic program at White Dam, targeting sulphide mineralisation beneath existing oxide prospects. A second diamond rig is also mobilising, but the next value test remains firmly in the ground: geophysical anomalies must translate into drilling results and an upgraded resource.
