GreenTech is moving quickly with its exploration programs at the Osborne JV in WA’s Pilbara region with a 1,500m diamond drilling program as it continues to reveal the true potential of its ground.

GreenTech’s (ASX:GRE) Osborne JV is held with Artemis Resources Artemis Resources (ASX:ARV), with GreenTech commanding 51% and Artemis the rest.

The asset sits to the east of the Ruth Well nickel-copper project in WA’s Pilbara region, next door to Azure Minerals’ (ASX:AZS) monster Andover lithium discovery.

Exploration work to date has confirmed lithium mineralisation at the Kobe prospect over a strike length of more than 7.5km and has highlighted the potential for a whole new mineralised trend, separate to Kobe, through recent high-grade rock chip samples.

These rock chip samples returned assay results of up to 3.63% Li2O on the so called ‘Southern LCT’ pegmatite zone, which comprises a total combined 4km of strike.

A previous review of historic soil geochemical data along with the results from ongoing geological mapping has confirmed the Northern and Southern LCT pegmatite zones, whilst significantly expanding the extent of lithium mineralisation in the project areas.

Drilling begins in ‘premier’ WA lithium hotspot

GRE has made another important step in its exploration works at Osborne with the commencement of up to 1,500m of diamond drilling to gather stratigraphic and structural information along the Southern pegmatite zone.

Focusing on existing heritage cleared areas, GRE executive director Thomas Reddicliffe says data from the program will aid in refining the more detailed follow up drilling program, which will begin once the results from broader heritage clearances are received.

“We are excited to begin this program,” he says.

“In light of the recent $1.6b takeover offer for Azure, the West Pilbara is continuing to cement its position as one of the premier global jurisdictions for hard rock lithium exploration.

“GreenTech is moving quickly with its exploration programs as it continues to reveal the true potential of its significant tenure in the region.”

More drill sites to open up

Field crews have mobilised on site and will be continuing various exploration activities during the maiden drilling program including mapping, rock chip and soil sampling as well as drill target identification and site preparation.

Further drill sites at both the Northern and Southern trends will become available in the next 4-6 weeks following the completion of the initial heritage survey.
