Latest Porphyry Systems News

Australian Critical Minerals has emerged from a transformational year with six new Peruvian projects and early Flint drilling pointing towards a possible concealed porphyry system. But the annual report also flags a material uncertainty over going concern, with further funding required to sustain exploration.

Freehill Mining’s Chilean aggregates operation reached record quarterly sales as the company moved deeper into copper-gold development. But the stronger operating performance came alongside a larger loss, negative operating cash flow and a material uncertainty over its ability to continue as a going concern.

Golden Mile Resources has reported broad, high-grade surface gold results at its Aurora prospect in Arizona, including 2.38g/t over about 126 metres. The exploration momentum comes alongside a $2.41 million annual loss, $609,757 in cash and an explicit warning that further funding is required.

Southern Hemisphere Mining has reported its strongest Llahuin drilling results yet, but the copper explorer ended FY26 with just $110,027 in cash and a material going-concern uncertainty. The company is relying on further funding, related-party borrowings, asset sales and a possible Chilean VAT refund to keep exploration moving.

A new magnetotelluric survey has identified a large conductive anomaly beneath Strickland Metals’ Obradov Prospect in Serbia, adding another high-priority target to its 9.25Moz AuEq Rogozna project. The anomaly is supported by overlapping gravity, IP, geochemical and drilling evidence, but still requires drilling to establish whether it contains an economic mineralised system.

FMR Resources has shifted decisively towards Chile, expanding its copper-gold portfolio while early Llahuin drilling suggests the interpreted porphyry core remains untested. The exploration push came with a $6.44 million loss, $4.65 million in cash and a renewed dependence on future capital.

Sarytogan Graphite has intersected 318 metres of copper mineralisation from surface at its Ilksan prospect in central Kazakhstan, including a higher-grade 15.2-metre zone grading 0.40% copper. The result extends the system identified in an earlier hole, with assays from a deeper 452-metre hole due in the coming weeks.

Tivan has secured a 50 km² exploration concession immediately north of its Turiscai project in Timor-Leste, subject to formal regulatory grant. The addition would lift the project to eight licences covering approximately 394 km² ahead of planned maiden drilling in the fourth quarter.

Sunstone Metals has completed its 30-hole Bramaderos resource-growth program with a 5.95m zone grading 26.61 g/t AuEq and a separate 367.99m mineralised intersection. The results will feed into a 2026 resource update expected in the coming quarter.

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.

Hot Chili has reported a 398-metre copper-gold intersection from surface at its La Verde discovery in Chile, including 62 metres at 0.91% CuEq. The results extend the case for a higher-grade starter pit, but the project remains an exploration discovery with no Mineral Resource declared.

Sunstone Metals has delivered robust drilling results at its Bramaderos Gold-Copper Project in Ecuador, expanding the Melonal porphyry system with long mineralised intervals and strong grades, setting the stage for a resource update.
