DRILLING UNDERWAY AT GIDJI JV GOLD PROJECT

Miramar Resources Limited (ASX:M2R , “Miramar” or “the Company”) is pleased to advise that drilling is underway at the Gidji JV Project in the world-class Eastern Goldfields Province of Western Australia.

Miramar’s 80%-owned Gidji JV Project (“Gidji” or “the Project”) is located approximately 15 kilometres north of Kalgoorlie and surrounded by multiple gold mining and processing operations, including Northern Star Resources Limited’s Kalgoorlie gold operations at Fimiston (Super Pit), Mount Charlotte and Kanowna Belle (Figure 1).

Miramar’s Executive Chairman, Mr Allan Kelly, said the current drilling programme will infill and extend the Marylebone, Blackfriars and Highway gold discoveries (Figure 2) whilst continuing to probe for bedrock gold mineralisation.

“Since commencing exploration at Gidji in late 2020, we have outlined several large supergene gold footprints under the Gidji Paleochannel, with multiple shallow high-grade gold intersections,” Mr Kelly said.

“The aim is to find the bedrock source of all that shallower gold,” he added.

About the Gidji JV Project

Miramar’s 80%-owned Gidji JV Project is located approximately 15 kilometres north of Kalgoorlie-Boulder and is one of three projects held by Miramar in the world-class Eastern Goldfields Province of WA.

Despite the Project being surrounded by multiple gold mining and processing operations, it has been underexplored due to extensive shallow transported cover and the Gidji Paleochannel which crosscuts the most prospective basement geology.

Since commencing exploration in late 2020, Miramar has made multiple large new gold discoveries with systematic aircore drilling and has defined multiple bedrock targets for deeper drilling.

Miramar believes there is potential for the discovery of a new gold camp, with multiple gold deposits, within the Gidji JV Project.
