Latest Porphyry Systems News

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.

FMR Resources has reported assay results from three diamond drillholes at the Southern Porphyry target within its Chilean Llahuin Project, confirming a large, vertically extensive porphyry-related hydrothermal system. While the causative porphyry core remains untested, elevated gold and molybdenum values suggest proximity, prompting plans for a focused Phase II drill program.

Golden Mile Resources Ltd (ASX: G88) has secured a binding joint venture to earn up to 95% interest in the Leviathan Porphyry Copper-Molybdenum Project in Arizona, with initial sampling confirming significant copper and molybdenum mineralisation and exploration set to begin in April 2026.
