Latest Porphyry Systems News

AusQuest has confirmed a vast copper-gold system at its Cangallo project in Peru, revealing broad mineralisation and multiple higher-grade zones. Meanwhile, exploration momentum continues in Australia under a South32 alliance, with key drilling programs poised to start.

Talisman Mining’s first air-core drilling at East Peak Hill in NSW uncovers promising gold and copper-cobalt-zinc mineralisation, setting the stage for a follow-up program in May to test vein-style gold and porphyry copper-gold targets.

Australasian Metals continues to build on its Queensland gold assets with a new exploration permit application and ongoing drill planning at May Queen, while holding a solid cash reserve of $2.46 million and progressing lithium project discussions.

Southern Hemisphere Mining has completed Phase I drilling at its Southern Porphyry target in Chile, confirming a large hydrothermal system and delivering encouraging assay results. The company is gearing up for Phase II drilling targeting the elusive high-grade core.

Sunstone Metals has delivered a robust Scoping Study for its Bramaderos Gold-Copper Project in Ecuador, outlining a 23-year mine life, strong production rates, and a post-tax NPV of US$0.9 billion at a conservative gold price. The study highlights low operating costs and substantial exploration upside, setting the stage for a pre-feasibility study and funding pursuits.

Lithium Energy has wrapped up diamond and air core drilling at the Bajool Prospect, unveiling geochemical trends aligned with a potential porphyry system, while awaiting critical diamond core assay results.

Antilles Gold has ramped up construction at its Nueva Sabana gold-copper mine in Cuba, with a $35 million funding package in place and production slated for early 2027. The company is also progressing pre-development and exploration activities on multiple Cuban concessions.

Altitude Minerals has completed extensive gravity and passive seismic surveys over its Byrock Project in NSW, validating key copper-gold porphyry targets and setting the stage for follow-up RC drilling in 2026.

Great Southern Mining (ASX:GSN) is set to restart diamond drilling at its Edinburgh Park joint venture in northern Queensland, focusing on the Mt Dillon target where a significant induced polarization anomaly suggests a large intrusive-related gold system.

AusQuest gears up for maiden drilling at two promising copper-gold prospects in Peru, aiming to build on the momentum from its Cangallo discovery. Over 8,000 metres of Reverse Circulation drilling are set to test high-priority IOCG and porphyry targets starting Q2 2026.

Sunstone Metals has kicked off its latest drilling campaign at the Bramaderos Gold-Copper Project with substantial mineralised intersections, reinforcing the potential to expand its 3.6 million ounce resource. The company prepares to release a scoping study that will clarify the project's economic outlook.

Southern Hemisphere Mining and partner FMR Resources have reported broad gold-copper-molybdenum mineralisation at the Southern Porphyry target in Chile, confirming a large porphyry system. Despite fertile intrusive phases intersected, the mineralised core remains elusive, setting the stage for targeted Phase II drilling.
