Great Boulder Resources Follows Rumble into Earaheedy Basin

THE BOURSE WHISPERER: Great Boulder Resources (ASX: GBR) has secured a major land position in the Earaheedy Basin, east of Wiluna in Western Australia.

Great Boulder Resources is following the example set by Rumble Resources, which this week announced its discovery of a major zinc-lead discovery at its Earaheedy project.

GBR lodged three new tenement applications over a second zinc-lead target identified to the southeast of Rumble’s project, to be named the Wellington project.

The new tenements exemplify nearology as they overlie the prospective Frere Formation within the Proterozoic Earaheedy Basin, with targets generated by GBR from analysis of publicly available geochemical data sets.

Great Boulder first identified prospective areas in the Earaheedy Basin in mid-2020 during a desktop study of the province’s regional potential, following initial promising drill results by Rumble.

The potential of the region was further validated by Rumble’s recent results which underpin a shallow, large-scale exploration target of 40 to 100 million tonnes at 3.5 per cent to 4.5 per cent zinc and lead over 40km of strike.

The new GBR tenement position covers an area of 1,134 square kilometres, including more than 60km of strike highlighted by pathfinder geochemistry.

This is a similar target scale to the early-stage exploration data that led to Rumble’s major discovery.

“This is an exciting development for Great Boulder as it gives us a massive landholding with a compelling large-scale target over a major new zinc-lead province in Western Australia,” Great Boulder Resources managing director Andrew Paterson said in the company’s ASX announcement.

“Having previously completed the targeting study during 2020 we were following Rumble’s progress closely, and we were able to act quickly on Monday to secure these tenements as soon as the scale of Rumble’s discovery became apparent.

“This doesn’t impact any of our current exploration priorities in the medium term.

“In effect, it’s a free option over an emerging, world-class base metals province that has the potential to add serious value to our project portfolio.”
