Latest Epithermal Systems News

Piche Resources has identified a broad gold-silver system at Toro Hosco in Argentina after completing its maiden 5,911-metre drilling campaign. The exploration progress came alongside a $5.27 million annual loss, $5.22 million operating cash outflow and reliance on post-year-end equity funding.

Pursuit Minerals posted an A$666,579 FY2026 profit, but the result was driven largely by a fair-value gain on its Kendrick Resources investment rather than operating revenue. The company’s more consequential development is in Argentina, where Rio Grande Sur now carries a 1.264 million tonne LCE resource, a maiden probable reserve and a pre-feasibility case for 5,000 tonnes per year of lithium carbonate.

Stavely Minerals has outlined a potentially valuable 13-year copper-gold-silver project, but its latest annual report makes clear that funding remains the immediate constraint. The company ended June with A$3.1 million in cash and an auditor-flagged material uncertainty over its ability to continue as a going concern.

Tolu Minerals has more than doubled its reported gold resources to 1.33 million ounces after declaring a maiden 293,000-ounce resource at Mt Penck in Papua New Guinea. The project also carries a largely untested copper-gold porphyry target, but its proposed A$30 million exploration program still requires separate funding.

Minrex Resources has completed its 33-hole Barje infill program and begun a 6,604-metre greenfield campaign at Tlamino in Serbia. The drilling will test whether Barje and Liska form part of a single mineralised system extending more than 1.5 kilometres.

Australian Critical Minerals says one extended drill hole at its Flint project in Peru has strengthened the case for a near-surface epithermal system and a deeper concealed porphyry target. The interpretation remains conceptual, with no economic-grade intersections or mineral resource reported.

Great Northern Minerals (ASX: GNM) reported a $3.8 million loss for FY26 amid major US acquisitions, including the Iron Butte gold-silver project with a maiden resource of 480,000 oz gold and 11.5 million oz silver, and the Catalyst Ridge rare earths project. The company also completed a $2 million divestment of its remaining Golden Ant interest.

Taruga Minerals has unveiled exceptional gold and silver assays from rock chip sampling at its East Normanby Gold Project, confirming extensive high-grade epithermal mineralisation across an 8km corridor. The company is set to kick off its maiden diamond drilling program at the Weioko Gold Deposit, with multiple new targets identified for follow-up.

Investigator Silver has reported extraordinary silver grades well beyond the current Paris Project pit limits, including an eye-watering 1m at 13,302g/t Ag, alongside discovery of a new silver-bearing system at Theseus. These results could significantly expand the project's resource base ahead of planned follow-up drilling.

Peako Limited has kicked off detailed UAV magnetic surveys across five prime targets in Saudi Arabia, setting the stage for maiden drilling campaigns this October.

SQX Resources launches a fully underwritten $2.47 million rights issue at a 31% discount to fund accelerated exploration across key US and Australian projects.

OD6 Metals consolidates progress across its rare earths, copper, and fluorspar assets with strong resource bases and ongoing development activities in Nevada, Western Australia, and New South Wales.
