Latest Resource Estimation News

OD6 Metals has identified high-grade fluorspar at North Horseshoe Canyon in Nevada, with selective rock-chip assays reaching 60% CaF2. The results expand an interpreted 1.5-kilometre target corridor linking the Horseshoe and Big Jim areas, but drilling is still needed to establish continuity, thickness and scale.

Sentinel Metals has reported broad, stacked gold mineralisation at its Columbia project in Montana, including a 48-metre intercept at 1.13g/t gold. Fire assays have also confirmed the company’s earlier high-grade maiden-hole result, while a November resource update now looms as the key test.

PC Gold has identified a historically sampled high-grade domain at Spring Hill, with a composite 20.35m channel result grading 13.04g/t gold outside the current resource estimate. The target has not been drilled, leaving continuity and true width unresolved ahead of planned testing in late September.

Critica has produced a second high-grade mixed rare earth carbonate from its Jupiter project, closely matching the first product at 57.9% TREO. The latest laboratory result also carried higher magnet and heavy rare earth content, strengthening the case for further flowsheet development ahead of a scoping study.

Morella has established a maiden 5.44 million tonne Inferred resource at Mt Edon containing approximately 8,300 tonnes of rubidium oxide. The estimate gives the project scale, but commercial value still depends on recovery, purification and a viable product route.

Great Northern Minerals has identified at least three undrilled chargeability anomalies at its Douglas Creek project in North Queensland, supported by gold, copper, silver and bismuth surface results. The targets sit around a large reverse-polarised magnetic tonalite body that extends to an interpreted depth of about 1 kilometre, but drilling is not expected until mid-2027.

Encounter Resources has reported its highest-grade niobium intersection yet at the Green Deposit, with drilling extending beyond the existing resource boundary. The result strengthens the case for further resource growth, but follow-up drilling is needed to establish continuity and true widths.

Australian Vanadium will pay $500,000 in cash, issue $1.25 million of shares and transfer a royalty to regain control of non-vanadium mineral rights at its Gabanintha project. The deal simplifies the project’s ownership structure, but the newly recovered nickel, copper and gold potential remains unproven and outside the current development case.

Corazon Mining has begun a 50-hole, approximately 7,500-metre RC drilling program at its Chalice Gold Project in Western Australia. The campaign will test near-surface extensions to the existing 191,000-ounce resource, while the company cautions that its larger 830,000-ounce Exploration Target remains conceptual.

Fulcrum Lithium has promoted Chief Operating Officer Scott Keenan to Managing Director, placing the executive who led its Alkali Flats discovery in charge of the company’s next project phase. The appointment comes with a $360,000 annual salary and a proposed 4 million performance-rights package subject to shareholder approval.

Tolu Minerals has increased the Tolukuma gold resource by 81% to 909,000 ounces after four months of full-scale drilling, pushing its reported Papua New Guinea gold inventory above one million ounces. The proposed early 2027 restart now has a larger resource base, but remains dependent on infrastructure, technical work and conversion of resources into mineable reserves.

Bass Oil has put a 1,280-barrel-per-day Bunian 6 test and planned Vanessa gas sales at the centre of its next growth phase. The company is also promoting Kiwi as a larger, longer-dated development opportunity, although much of the upside remains subject to testing, funding and execution.
