Miramar Resources Limited has transitioned its Gidji JV Gold Project from an exploration prospect to a defined resource, outlining a maiden Inferred Gold Resource of 1.04 million tonnes grading 1.20 g/t Au for 39,764 ounces of contained gold.

The resource base replaces the project’s previously disclosed exploration target, which had spanned a tonnage range of 6.18 million to 7.56 million tonnes containing 127,352 to 330,431 ounces of gold across six domains. The newly declared resource is distributed across shallow targets including Marylebone, Powerline, Blackfriars and Highway, situated 15 kilometres north of Kalgoorlie in Western Australia.

The figures are reported on a 100% basis above a 0.2 g/t Au cut-off, with mineralization optimized within pit shells modeled at A$7,500/oz. Miramar holds an 80% interest in the project through its subsidiary Miramar Goldfields Pty Ltd, operating in a joint venture with Thunder Metals Pty Ltd.

“We're thrilled to announce these Maiden Inferred Gold Resources which are a key step towards progressing Gidji from an exploration project into a development opportunity.”

— Marion Bush, Chief Executive Officer

The mineral inventory sits as a series of flat-lying blankets at depths between 40 and 50 metres below surface, constrained primarily by a lack of deeper drilling. The company raised $1.49 million under a placement completed in March 2026 to fund exploration across its portfolio, including work at Gidji.

“While these Resources give an indication of the scale, grade and potential economic significance of the shallow gold we've discovered at Gidji, we believe that an even more exciting opportunity is that each of these Resources potentially represents the tip of a much larger bedrock iceberg.”

— Marion Bush, Chief Executive Officer

The resource is classified entirely as Inferred and assumes open-pit contract mining with off-site toll treatment, relying on the oxide nature of the material without metallurgical testwork.

Miramar plans to submit a Mining Lease application for the property and conduct further drill programs designed to expand the shallow inventory.
