Latest Surface Sampling News

LE Minerals has confirmed lithium-bearing brines across its White Plains project in Utah, with 12 direct push holes returning grades of up to 114 mg/L at 15 metres. The company will now work towards a maiden JORC Mineral Resource, although five southern auger sites produced no brine and several claims were not renewed.

Cosmo Metals has secured a new exploration licence in New South Wales after reconnaissance work found copper-bearing outcrop and a selective rock chip sample grading 4.69% copper. The result is an early exploration signal, not evidence of a defined deposit, with mapping and further sampling still to come.

Golden Mile Resources says follow-up surface sampling has expanded the exposed Aurora gold anomaly in Arizona to at least 280 metres wide and 450 metres along strike. The results strengthen the case for drilling, although the prospect remains an early-stage, undrilled target with open boundaries.

OD6 Metals has extended its Rocket-Big Jim-Spar fluorspar corridor at Quinn in Nevada to approximately 700 metres, with six surface samples returning at least 97% CaF₂ and three reaching 99.9%. The results expand the project’s high-grade story, but remain based on selective rock-chip sampling rather than drilling.

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.

Evion has identified a previously unmined 200m by 200m prospect at its Carp Fluorspar Project in Nevada, just 300m from the historic South Pit. Assays are pending, with geophysical surveys and a potential maiden drilling programme next in line.

FMR Resources has identified a strong induced polarisation anomaly beneath historical artisanal workings at its Esperanza prospect in Chile, marking it as a priority drill target. The result is encouraging, but remains an early-stage geophysical signal pending 3D modelling, fieldwork and drilling.

Olympio Metals has begun field exploration across its Jacknife and Raven silver projects in the United States, with drilling at Jacknife expected to start imminently. A replacement announcement also strengthens the company’s description of a historical foreign estimate, while making clear that the estimate remains non-JORC and requires fresh verification.

Sky Metals has identified high-grade tungsten mineralisation at the Theirman Mines Prospect, 20 kilometres north of its Tallebung project in NSW. The results validate historical sampling and move the prospect towards drilling within weeks, although the evidence remains limited to surface rock chips.

Diablo Resources has exercised its option over 101 patented claims covering the historic Horn Silver Mine in Utah, bringing its broader 202-claim, 13.2 square kilometre project package together. The company will now rank targets, advance permitting and prepare for a maiden Horn Silver drilling program in 2026.

Patronus Resources has defined a new 1.5km-long gold anomaly at J25 in the Northern Territory, with surface assays reaching 0.99g/t Au. The result expands a growing target pipeline just as four drill rigs move from target generation to testing.

Tivan Limited’s latest bulk assays from Timor-Leste confirm high-grade copper and gold mineralisation, sharpening focus on the Vemasse and Scorpion prospects for drilling later this year.
