GreenTech Metals Ltd (ASX:GRE) is advancing its multi-commodity land package in the West Pilbara in Western Australia with a strong focus on lithium exploration on its Ruth Well project tenements.
The company also has significant copper resources at its Whundo Project of 6.2 million tonnes at 1.2% copper and 1.04% zinc as well as 265,000 tonnes at 0.5% nickel and 0.4% copper at Ruth Well.

A project scale mapping and rock chip sampling program is now well underway at Ruth Well targeting historical lithium and associated pathfinder soil geochemical anomalies identified by the GreenTech technical team.
In total, nine broad lithium soil anomalous zones have been identified across the licence package covering a combined total area of 32 square kilometres with more than 60 square kilometres still to be mapped.
Importantly, GreenTech considers a number of these target areas in addition to the Kobe and Osborne zones to have the potential to support significant occurrences of lithium bearing pegmatites.
Lithium bearing pegmatites identified
Mapping and recent sample results have now confirmed the discovery of new occurrences of lithium bearing pegmatites (Wally, Osborne and Maddox Zones) which also correlate with a number of lithium soil anomalies and regional structures.
These newly discovered pegmatite zones are about 5 kilometres south of the Kobe lithium-pegmatite zone which previously reported multiple high-grade lithium assays up to 1.8% lithium oxide.

Forward exploration program
Sampling and mapping are continuing and are aimed at defining the spatial extent of the two pegmatite zones and the consistency of the lithium mineralogy and grade within these mineralised pegmatite systems.
High resolution satellite imagery has also been acquired to further assist in identifying additional pegmatite zones, and soil sampling is underway in selected areas where historical soil sampling has indicated the potential presence of lithium pegmatite.
Maiden drilling program
GreenTech has completed preparations to start a maiden drilling program.
The initial program will be a core drilling program of ~1,000 metres aimed at providing subsurface information on the dip and thickness of the pegmatite packages which will be used to plan a follow-on broader RC drill program.
The program will start at the Osborne southern cluster of pegmatites in early November.
GreenTech is well funded to advance its work programs with ~$2.9 million cash at September quarter end.
