Minyari Project Now Hosts 2.5Moz Gold Plus 84,000 Tonnes Copper and 13,000 Tonnes Cobalt

Resource Growth and Project Scale

Antipa Minerals Limited (ASX: AZY) has announced a significant update to the Mineral Resource Estimate (MRE) for its wholly owned Minyari Project in Western Australia's Paterson Province. The total gold resource has grown by 100,000 ounces, now standing at 2.5 million ounces, complemented by substantial quantities of copper, silver, and cobalt. This update brings the gold equivalent resource to 3.0 million ounces at a grade of 1.94 grams per tonne, underscoring the project's considerable scale and potential.

The Minyari Project’s resource base now includes 84,000 tonnes of copper, 666,000 ounces of silver, and 13,000 tonnes of cobalt, highlighting the multi-commodity nature of the deposit. The resource is distributed across several deposits including Minyari Dome, Tim’s Dome, and Chicken Ranch, with mineralisation starting at surface and remaining open along strike and at depth, suggesting further upside.

Strategic Location and Development Potential

Situated between 10 and 35 kilometres from Greatland Gold’s Telfer gold-copper-silver mine and processing facility, the Minyari Project benefits from proximity to established infrastructure and a proven mining jurisdiction. Antipa’s Managing Director, Roger Mason, emphasized the strategic advantage of this location, drawing parallels with the nearby Havieron development, which serves as a compelling analogue for Minyari’s future production potential.

The recent scoping study completed in October 2024 confirmed the project’s standalone development viability, with indications of a scalable operation combining open pit and underground mining methods. The mineralisation’s continuity and grade support reasonable prospects for eventual economic extraction, bolstered by positive metallurgical test work demonstrating excellent recoveries for gold and promising results for copper and cobalt by-products.

Ongoing Exploration and Growth Strategy

Antipa is well funded and has outlined a comprehensive two-phase drilling program for 2025 aimed at expanding the existing resource base and exploring new discovery zones. Phase 1 targets include high-priority areas such as the GEO-01 Main Zone and Minyari South, where mineralisation remains open and untested at depth. Phase 2 will focus on down-plunge extensions and satellite deposits like Tim’s Dome and Chicken Ranch, which have recently been consolidated back under Antipa’s full ownership.

The company’s exploration approach leverages detailed geological modelling, structural analysis, and advanced sampling techniques to refine resource estimates and identify new targets. The ongoing metallurgical test work, particularly at the GEO-01 deposit, continues to yield encouraging results, including lower cyanide consumption compared to other deposits, which could enhance processing economics.

Environmental and Regulatory Considerations

While the project is still in the advanced study phase, Antipa has initiated environmental desktop studies and on-ground surveys to assess flora, fauna, hydrology, and hydrogeology. These efforts aim to inform future environmental management plans and ensure responsible development. The company acknowledges the presence of sulphide minerals and plans to incorporate acid mine drainage considerations into future resource iterations.

Antipa’s tenure in the region is secure, with exploration licences in good standing and no known impediments. The company maintains strong relationships with local native title holders and continues to operate with respect for environmental and cultural sensitivities.
