Latest Diamond Drilling News

Estrella Resources has identified copper-bearing porphyritic diorite and gold at nine locations around Timor-Leste’s Laleno Dome, strengthening the case for a broader intrusion-related system. The geological signal is encouraging, but drilling approval and representative follow-up work remain outstanding.

Solstice Minerals has extended the Nanadie copper-gold system to at least 1.5km of strike, with deep diamond drilling returning broad mineralisation beyond the current resource boundary. The results include a 169.3m intercept at 0.87% copper and 0.29g/t gold, while more than 40 holes remain awaiting assays.

WhiteRock Lithium has intersected spodumene-bearing pegmatite in all 10 newly reported drill holes at its Spodumene Mountain prospect in Québec. The visual results strengthen the geological case for continuity, but assays and true widths are still pending.

Pantoro has increased Norseman’s Mineral Resources by 2% and Ore Reserves by 9% after mining depletion, with the Mainfield delivering the clearest growth. The company also reported a $113.2 million FY2026 profit, but the next test is converting a larger geological inventory into sustained production.

West Coast Silver will begin an 18-hole diamond drilling campaign at Elizabeth Hill in October, targeting resource upgrades, western extensions and a newly defined high-grade zone. The results are intended to feed Mineral Resource Estimate updates and a scoping study in 2027.

Magnum Mining’s latest 65-hole assay batch strengthens the Plateau Zone at Piracanjuba North, where desorbable rare earth results matter more than headline grade. The company now has assays from 373 of 894 drilled holes and is targeting a maiden JORC Mineral Resource Estimate by the end of November 2026.

Lincoln Minerals has moved Minbrie’s Eagle Ridge prospect towards diamond drilling after air core work supported its geological model. But the ASX-listed explorer remains loss-making, cash-burning and dependent on further funding to continue its exploration program.

Golden Horse Minerals has reported its strongest gold intercept at Hopes Hill, with RC hole 26HHRC179 returning 4 metres at 73.3 grams per tonne gold from 88 metres. The result includes visible gold and a 293.2 gram-metre intercept, but its nuggety character means follow-up drilling and sampling will be crucial.

Brightstar Resources has nearly doubled the Two Mile Hill-Shillington Mineral Resource to 1.45 million ounces, with the Indicated component rising 177% to 526,000 ounces. The result lifts the broader Sandstone Gold Project to 3.6Moz, while assays from deeper drilling could provide another resource catalyst later in 2026.

Perpetual Resources has warned of material uncertainty over its ability to continue as a going concern after its FY2026 loss more than tripled. The ASX-listed explorer finished the year with A$2.34 million in cash, but remains dependent on further capital raisings to fund Nevada Scheelite and Brazilian exploration.

Lord Resources has extended copper mineralisation across multiple lodes at Ilgarari, but its FY2026 annual report carries a material uncertainty over whether the explorer can continue as a going concern. The company ended the year with $554,820 in cash after a $2.54 million loss and $1.87 million of operating cash outflows.

Mt Malcolm Mines has moved closer to an integrated gold development model, combining a maiden 13,200-ounce resource with ownership of major 500,000-tonne-per-year processing plant components. The shift came with a $1.639 million loss, $1.445 million of operating cash outflows and a warning that further working capital is likely to be required within 12 months.
