Latest Mineral Resource Estimation 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.

Golden Horse Minerals has expanded the interpreted Hopes Hill gold system beyond 3 kilometres after completing 52,762 metres of drilling in the six months to June 30. The exploration push delivered multiple high-grade intersections and free-milling metallurgy, but came with no revenue, a $4.37 million loss and a sharp drawdown in cash.

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.

Ore Resources has extended lithium mineralisation beyond the current resource boundaries at its Big Red and Potoroo pegmatites, with drilling still open to the north and west. The results add exploration upside to Kangaroo Hills as the company advances strategic discussions and approvals for a potential DSO operation.

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.

LinQ Minerals has reported broad, shallow copper-gold intersections at Monza, including 113 metres at 0.71% copper equivalent from 33 metres. Mineralisation remains open in multiple directions, while a largely untested corridor could connect Monza with the nearby Estoril resource.

Kingfisher Mining has remade itself around a 700 square kilometre New South Wales exploration portfolio, with Copper Blow emerging as the flagship after high-grade drilling. The shift came alongside a $1.16 million FY2026 loss, $1.21 million in cash and an explicit reliance on future funding.

Terrain Minerals has secured a $1 million commitment from Gandel Metals at a 33.33% premium to market, anchoring a broader $2.513 million placement and rights issue. The funds will support the company’s largest planned RC drilling campaign at the Lightning gold and silver project.

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.

Magnum Mining has defined a connected 32.5km² Plateau Zone at its Piracanjuba North project in Brazil after positive results from another 86 auger holes. The company is targeting a maiden JORC Mineral Resource Estimate in November 2026, but the latest desorption figures remain laboratory screening results rather than recoveries or economic data.

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.
