Latest Economic Assessment News

Larvotto Resources has extended high-grade antimony-gold-tungsten mineralisation at Clarks Gully about 100 metres beyond its 2025 resource model, with drilling also identifying several hanging-wall lodes. The results could support a larger resource and a potential underground feed source for Hillgrove, but assays, modelling and permitting work remain outstanding.

Independent LONGi testwork has produced 66.3% to 68.0% Fe magnetite concentrates from four Magnetite Range samples using a bench-scale dry flowsheet. The results strengthen the case for a water-efficient route in Accent Resources' pre-feasibility study, but remain preliminary and untested at pilot scale.

Sultan Resources has reported a $1.48 million FY2026 loss and an auditor-highlighted material uncertainty over its ability to continue as a going concern. The explorer is seeking to fund early-stage Lachlan Fold Belt work while pursuing a new Namibia opportunity and a post-year-end $1.316 million placement.

Tempest Minerals has reported a $4.62 million FY2026 loss after impairing $3.28 million of exploration assets, while cash fell to $969,693. The company retains exposure to Range gold drilling, the Remorse iron deposit and a $3.08 million Capricorn Metals shareholding, but says further funding will be needed to sustain exploration.

PTR Minerals has posted a 463 million tonne maiden resource for its Rosewood titanium project, backed by strong early processing results and fresh funding. The next test is whether the large geological inventory can become an economically viable mine.

Unico Silver has more than tripled its reported silver-equivalent resource base across Joaquin and Cerro Leon, ending FY26 with A$55.1 million in cash and a maiden Joaquin Pre-Feasibility Study ahead. The next stage will test whether geological scale can become an economically viable project.

Australian Gold and Copper expanded its exploration footprint and advanced major targets during FY2026, but the campaign came with a larger loss and a sharp reduction in cash. The company now has a 38.5Moz silver-equivalent Achilles resource, a newly acquired Junee gold portfolio and further funding demands ahead.

Mithril Silver and Gold has lifted the higher-confidence portion of its Copalquin Target 1 resource to 464,000 ounces of gold equivalent, giving the Mexican project a stronger base for mine planning. The upgrade comes alongside a larger loss, substantial exploration spending and an auditor’s warning that further funding is needed to support the company’s going-concern status.

IperionX has moved its Virginia titanium operation into 24/7 production, lifting nameplate powder capacity to about 200 tonnes a year while commissioning equipment aimed at higher-value components. The progress came alongside a US$66.8 million annual loss, US$63.5 million of operating and investing cash outflows, and continued reliance on government support, customer qualification and future capital.

Redcastle Resources has quantified 6,600 ounces of gold already mined and sitting on its ROM pad, but the inventory remains a Mineral Resource rather than an Ore Reserve. The stockpiles are ready to move, although processing arrangements are still being negotiated and mining is currently suspended.

Pantoro has increased Norseman’s Mineral Resources by 2% and Ore Reserves by 9% after mining depletion, with the Mainfield delivering the clearest growth. The company also reported a $113.2 million FY2026 profit, but the next test is converting a larger geological inventory into sustained production.

Tyranna Resources has signed a binding earn-in agreement covering the 830 km² Coola Rare Earths and Niobium Project in Angola, with two carbonatite-bearing intrusions already mapped. The deal remains conditional on renewal of the project tenement, while a proposed 500 million-option grant adds a significant shareholder-approval question.
