• GreenTech Metals rock chip sampling returns up to 2.31% Li2O at West Pilbara lithium projects
  • Results confirm continuity of pegmatite hosted lithium mineralisation along 7.5km Kobe trend
  • Maiden drilling planned to commence this month


Special Report: Infill outcrop sampling and mapping at GreenTech Metals’ West Pilbara lithium projects in WA have returned up to 2.31% Li2O at the western end of the 7.5km long Kobe trend.

The company’s West Pilbara lithium projects are close to Azure Minerals’ (ASX:AZS) Andover project, where major shareholder Chilean firm SQM – one of the world’s largest lithium producers – put in a massive offer for the Aussie explorer back in October.

GRE’s Northern LCT pegmatite (including the Kobe prospect) sits within the company’s 100%-owned Ruth Well project tenements along 6km of strike where previous rock chip samples returned assay results of up to 1.82% Li2O.

GreenTech Metals (ASX:GRE) says these new rock chip results further demonstrate the persistence of the lithium mineralisation along the entire Kobe pegmatite trend.


Lithium all along the 7.5km trend

Notable rock chip sampling assays at the West end of the Kobe trend include:

  • 2.31% Li2O, 25ppm Ta2O5 and 120 ppm Nb2O5 (sample 23GT20-832);
  • 1.72% Li2O, 52ppm Ta2O5 and 118 ppm Nb2O5 (sample 23GT20-797);
  • 1.37% Li2O, 38ppm Ta2O5 and 57 ppm Nb2O5 (sample 23GT20-801);
  • 1.24% Li2O, 23ppm Ta2O5 and 113 ppm Nb2O5 (sample 23GT20-830);
  • 1.23% Li2O, 70ppm Ta2O5 and 81 ppm Nb2O5 (sample 23GT20-804); and
  • 1.20% Li2O, 21ppm Ta2O5 and 92 ppm Nb2O5 (sample 23GT20-835).

“Exploration work across these key targets within our West Pilbara lithium portfolio continues to yield exceptional results,” executive director Thomas Reddicliffe said.

“These latest sampling assays continue to demonstrate the continuity of lithium mineralisation along the 7.5km Kobe pegmatite trend.

“GreenTech continues to systematically unlock the scale and mineralised potential of its tenements in the West Pilbara region, an address which has quickly become one of the premier global jurisdictions for hard rock lithium exploration.

“We look forward to reporting regular updates on our exploration progress.”

Maiden drilling planned this month

The company is also continuing to research and review historic datasets with a view to identifying new lithium pegmatite trends, and extensions to the known trends, within the broader Ruth Well and the nearby Osborne JV in WA with Artemis Resources (ASX:ARV).

Infill soil sampling is being completed in the ‘Southern Trend’ at Ruth Well to better define lithium in soil anomalies highlighted in historic soil sample data sets, which may potentially lead to the identification of additional pegmatite trends beneath the shallow soil cover – and which can then be confirmed by drill testing.

In addition, a heritage report for the recently completed initial heritage survey has been received enabling access for drilling at Kobe, with maiden drilling to test Kobe planned to commence this month.

“Diamond drilling is also underway at Kobe aimed at providing stratigraphic/structural information and subsurface characteristics of these pegmatite zones in preparation for a refined follow-up drilling program early next year,” Reddicliffe said.
