Antares Metals Advances WA Gold-Copper and Mt Isa Uranium with Major Drilling Plans

Strategic Expansion of Western Australian Gold-Copper Portfolio

Antares Metals (ASX:AM5) has solidified its foothold in Western Australia with the formal acquisition of 100% interests in the Quinns and Katanning projects, expanding its Quinns footprint to a substantial 383km². The Quinns Project, positioned within the Meekatharra greenstone belt and close to established mills operated by Monument Mining and Westgold Resources, has delivered promising early-stage gold results, including rock chip samples up to 3.7 g/t Au from previously unexplored historic workings. Soil geochemistry has extended key gold targets by 200 metres and remains open-ended, highlighting the potential for further discovery. The company secured Program of Work (PoW) approval, enabling imminent drilling to test these targets. This aggressive expansion and exploration push signals Antares’ commitment to unlocking orogenic gold potential by applying modern techniques to underexplored greenstone belts. The company is also preparing a first-pass exploration program at Katanning, targeting extensions of a neighbouring 2.44Moz gold resource along strike.
These developments build on the momentum from Antares’ recent Expansion of Quinns Copper Gold Project announcement, where the company outlined its strategy to systematically advance the WA gold portfolio towards drilling.

High-Grade Copper-Gold Mineralisation Confirmed at Mt Isa North

At its Mt Isa North project in Queensland, Antares has uncovered compelling copper-gold mineralisation beyond the established Cromwell Prospect. Rock chip sampling at the Startle Prospect returned exceptional grades, including a peak of 27.0% copper, 2.66 g/t gold, and 31 g/t silver across a 350-metre strike. Similarly, the Astound Prospect revealed a 10-metre-wide shear zone with copper grades up to 12.9% and gold up to 1.09 g/t. These results underscore the district-scale potential of the tenements and add a new dimension to the company’s copper portfolio.
Future work at these prospects will involve detailed mapping, geophysical surveys, and maiden drilling to test the continuity of the mineralised zones. The high-grade copper-gold results complement Antares’ ongoing efforts to build a significant resource base in the Mt Isa region, enhancing the project's profile within a prolific mineral province.

Queens Gift Drilling Confirms High-Grade Uranium Mineralisation

Antares’ maiden reverse circulation (RC) drilling campaign at the Queens Gift Uranium Project has intersected high-grade uranium mineralisation in all five holes, including a standout intercept of 20 metres at 741 ppm U₃O₈, with 8 metres grading 1,288 ppm U₃O₈. These results validate the continuity of mineralisation beneath the historical JORC 2004 resource and support the company’s objective to upgrade to a JORC 2012-compliant Mineral Resource Estimate. The uranium system remains open at depth and along strike, offering potential for resource growth.
This drilling success follows the company’s earlier High-Grade Uranium Intersected at the Queens Gift Uranium Project announcement and sets a clear pathway for further exploration and resource definition activities in the coming quarters.

Conglomerate Creek Drilling Set to Test High-Priority Copper-Gold Targets

Antares is gearing up for a maiden 1,000-metre RC drilling program at its Conglomerate Creek prospect, targeting seven high-priority geophysical anomalies interpreted to be linked to a buried intrusion. Surface rock chip sampling has returned impressive assays, including up to 21.3% copper, 1.72 g/t gold, and 506 g/t silver from quartz veins associated with intense alteration. Elevated pathfinder elements like bismuth and tungsten further indicate an intrusion-related mineral system.
The drilling campaign, scheduled for late May 2026, aims to test these targets for depth extensions and mineralisation continuity. This initiative marks a critical step in advancing the Mt Isa North copper-gold portfolio and could significantly enhance the project’s resource potential, as detailed in the recent Antares Metals Sets May Drilling at High-Grade Conglomerate Creek Prospect update.

Corporate Advances Support Exploration Drive

To fuel its accelerated exploration programs, Antares completed the second tranche of a $2 million placement, raising approximately $970,000 at $0.008 per share. The placement included free-attaching options exercisable at $0.02, providing further capital flexibility. Concurrently, the company appointed Terry Topping as Managing Director, bringing extensive experience in gold and base metals exploration across Western Australia and Queensland. This leadership change coincided with the completion of the WA acquisitions and signals a focused executive approach to advancing Antares’ multi-commodity portfolio.
As at 31 March 2026, Antares holds $1.2 million in cash, positioning it to sustain ongoing exploration activities across its diversified projects. The company remains committed to converting exploration momentum into tangible value through resource definition and targeted drilling campaigns.
