GNAWEEDA ACQUISITION EXPANDS MEEKATHARRA FOOTPRINT

HIGHLIGHTS

• ➢ GBR acquires 100% of 61km[2] tenement at the southern end of the Gnaweeda belt

• ➢ The tenement located 10km east of Side Well abuts Meeka Metals’ tenure to the north

• ➢ Potential for gold mineralisation along the Turnberry – St Anne’s trend

➢

Great Boulder Resources (“ Great Boulder ” or the “ Company ”) (ASX: GBR ) is pleased to announce the acquisition of a 61km[2] exploration licence at Gnaweeda, located 10km east of the Side Well Gold Project (“ Side Well ”) near Meekatharra in Western Australia.

Great Boulder’s Managing Director, Andrew Paterson commented:

“This acquisition within 10km of Side Well and at the southern end of Meeka Metals’ project is an opportunistic addition to Great Boulder’s portfolio. It sits over the southern end of the Gnaweeda greenstone belt and straddles the same Proterozoic dyke that cuts through Mulga Bill.”

“There appears to be a thin blanket of alluvial cover obscuring the underlying geology and very little previous exploration has been conducted. I think both factors play to our strengths, given Great Boulder’s success at the Mulga Bill deposit and our refined technique for exploring in this type of terrain.”

“The $10,000 acquisition cost makes this a low-risk entry into a mineralised greenstone belt that is currently producing some extremely exciting drill results at Meeka Metal’s St Anne’s project to the north[1] .”

Acquisition Details

A 100% interest in E51/1995 was acquired from Empire Resources Ltd (ASX:ERL) for consideration of AUD10,000 plus a 1% gross revenue royalty. The tenement, considered by Empire to be a noncore asset, was first granted on 9/7/2021 and is in good standing.

Next Steps

Great Boulder’s exploration team will collate and assess any historic exploration data available on the DMIRS WAMEX database. Field reconnaissance and regolith mapping will be completed prior to commencing initial geochemical exploration programs.
