Latest Diamond Drilling News

Manuka Resources has reported several high-grade, shallow gold intersections from its Pipeline Ridge drilling campaign, led by 32 metres at 7.98 grams per tonne. The results support a maiden resource estimate, but metallurgy, true widths and resource classification remain unresolved.

Kuniko has extended the interpreted Silica Hill mineralised system by about 100 metres, with drilling encountering a broad sulphide zone and veins up to 50 centimetres thick. The key test now shifts to laboratory assays, due in four to six weeks, ahead of a planned December 2026 resource upgrade.

Unity Metals has identified a series of demagnetised zones across more than 6km at its O’Phlay project in Cambodia, using drill-core data to refine targets for additional gold mineralisation. The company plans at least 22 holes across several prospects from early October.

Gateway Mining has identified a 3km undrilled gold target at Pewy, where geophysical features and nearby aircore results resemble the setting that preceded its Cowza discovery. First-pass drilling is scheduled for early October, backed by the company’s recently completed $45 million placement.

Rox Resources has started surface diamond drilling at Youanmi, targeting resource conversion, incremental growth and deeper extensions of the high-grade United North system. The campaign could support future reserve growth and mine-life extensions, but its value still depends on drilling results that have yet to arrive.

Gateway Mining has secured firm commitments for a A$45 million placement, including A$20 million from Jupiter Asset Management, to fund an aggressive exploration campaign at its Yandal Gold Project. The raising follows a high-grade Cowza result and will issue 562.5 million new shares at a discount to market.

Oceana Metals has begun its first rare earths-focused drilling campaign at Serra Negra in Brazil, targeting a high-grade central corridor ahead of a maiden JORC resource estimate. The program starts with two rigs and is backed by A$8.16 million in cash plus a further $12.6 million from a July placement tranche.

Culpeo Minerals has started a four-hole, 2,000-metre maiden diamond drilling programme at Vista Montana, testing a copper-molybdenum target north-east of its Lana Corina discovery. The company is also using IP surveys to refine targets, while assays from El Quillay South returned several narrow copper-gold intersections.

Catalyst Metals has lifted the Keillor gold Resource from 81koz to 307koz after a major drilling campaign, while the operating mine ramps up near the Plutonic processing plant. The company expects an Ore Reserve update to extend Keillor’s initial three-year mine life.

Kali Metals has reported a 2.36-metre intersection grading 10.8g/t gold from just 8.7 metres at its Marble Bar project in Western Australia. The Phase II results extend the shallow gold system across a cumulative 3km strike, but the project remains at the exploration stage with no mineral resource yet defined.

Marimaca Copper has reported a 216-metre sulphide intersection grading 0.96% copper and 7.2g/t silver at Pampa Medina, including 62 metres at 2.20% copper and 21.5g/t silver. Step-out drilling also extended mineralised horizons beyond the central zone, while diamond drilling is now testing deeper ground to the north and northwest.

Haranga Resources is preparing to begin a 16-hole underground drilling campaign at its Lincoln Gold Project, targeting the southern resource and an under-drilled gap between the Lincoln and Comet zones. The programme arrives alongside new underground power infrastructure, completed dewatering and several assays that could shape a later resource update.
