Latest Reserves News

NuEnergy Gas has removed an OGIP and resource-density chart from its investor presentation and warned investors not to rely on the retracted information. The amended document also corrects a resource classification and adds cautionary language around undiscovered and undeveloped gas resources.

Aspire Mining has retained the Ovoot project’s 130.1 million-tonne JORC Coal Reserve while redesigning how the Mongolian mine is funded and built. The refreshed model forecasts a US$1.48 billion post-tax NPV10, but depends on debt raising, infrastructure delivery and a 12% Inferred Resource contribution to planned output.

Anson Resources has secured approval for an estimated US$212 million post-performance tax credit tied to its Green River Lithium Project in Utah. The benefit could materially improve the project’s projected economics, but it will only be realised if the project proceeds, generates tax revenue and meets the scheme’s conditions.

WhiteRock Lithium has sharply reduced a prospectus accounting adjustment after determining 11.8 million unexercised warrants should not have been remeasured. The correction comes as the newly ASX-listed explorer reports a C$3.19 million after-tax loss and more than C$33 million raised in 2026.

Alkane Resources has lifted group Ore Reserves to 1.374 million ounces after exploration and resource conversion replaced depletion across its operating portfolio. The FY26 update also puts Björkdal’s open-pit restart and Costerfield’s extended mine life into sharper focus.

Maritana Minerals has increased the Burbanks Gold Project’s Mineral Resource by 62% to 755,000 ounces, pushing group resources above 2 million ounces. The growth is concentrated at Burbanks North, but the inventory remains predominantly Inferred and has yet to support an Ore Reserve.

BPM Minerals has secured the final approvals for a maiden approximately 10,000-metre RC drilling campaign at its untested Bonnie and Clyde prospect in Western Australia. Drilling is expected to begin within 5-10 days, putting a more than 6-kilometre gold-in-soil anomaly to its first meaningful test.

Great Dirt Resources has identified 24 priority manganese targets in New South Wales and confirmed rock-chip grades of up to 51.8% manganese. The exploration progress came alongside a $19.1 million FY2026 loss, largely caused by a non-cash share-based payments expense, while cash rose to $3.81 million.

New Age Exploration reported its strongest exploration results to date across three projects, including a 11.0 g/t gold intercept at Wagyu and a new mineralised zone at Lammerlaw. But the explorer’s $4.21 million loss, $2.48 million impairment and auditor-flagged going concern uncertainty leave its next drilling campaign dependent on further funding.

Bass Oil has returned to profit for the first half of 2026, with EBITDA rising 80% and cash reserves strengthening while the company remains debt-free. The result comes as it moves towards first gas from Vanessa, advances the Kiwi project and prepares to tie in the stronger-than-expected Bunian 6 well.

Otto Energy’s attempt to sell its Gulf of America assets as a package has produced no actionable transaction, with GC 21’s decommissioning liabilities emerging as the central obstacle. The company will now pursue a separate sale of SM 71 while weighing other ways to manage GC 21.

Black Cat Syndicate has extended gold mineralisation beyond the current resource boundary at Trojan after completing a 56-hole, 6,804-metre RC drilling program. The results support further drilling and a potential resource upgrade, although the new intercepts are exploration results rather than an updated Mineral Resource.
