GreenTech Metals Release Further High Grade Rock Chip Results

30 October 2023 14:39

GreenTech Metals (ASX:GRE) continues to make progress at its West Pilbara Lithium Projects, releasing promising results of infill outcrop sampling and mapping at its wholly-owned Ruth Well and at the Osborne JV, in which it holds a 51 percent interest.

Excellent Lithium Results

The Company has outlined rock chip samples at the Kobe prospect, located within its Ruth Well Project, have returned excellent lithium grades of up to 1.82% Li2O along the 7.5 kilometre Kobe trend.

Notable rock chip sampling assays from the Kobe Prospect include:

  • 1.82% Li2O, 45ppm Ta2O5 and 80 ppm Nb2O5 (sample 23GT20-509)
  • 1.41% Li2O, 131ppm Ta2O5 and 74 ppm Nb2O5 (sample 23GT20-531)
  • 1.27% Li2O, 88ppm Ta2O5 and 76 ppm Nb2O5 (sample 23GT20-505)
  • 1.16% Li2O, 115ppm Ta2O5 and 107 ppm Nb2O5 (sample 23GT20-465)
  • 1.14% Li2O, 26ppm Ta2O5 and 83 ppm Nb2O5 (sample 23GT20-439)
  • 1.08% Li2O, 93ppm Ta2O5 and 114 ppm Nb2O5 (sample 23GT20-434)

Unlocking the Pilbara’s Potential

Located in the prolific Pilbara region, and in close proximity to mining giant Azure Minerals (ASX:AZS), the tenements are potentially highly prospective for lithium and LCT mineralisation.

Historic soil geochemical data, in addition to the results from ongoing geological mapping, has confirmed the Northern and Southern LCT pegmatite trends, located across the Kobe Prospect, whilst significantly expanding the extent of lithium mineralisation in the Project areas.

In June, GreenTech announced the rock chip sampling results from its Osborne JV Project, uncovering a new high-grade pegmatite trend showing assays up to 3.6% Li2O.

Future Exploration

GreenTech has outlined mapping and rock chip sampling are ongoing at the Projects, with a programme currently underway of infill soil sampling to test the southern trend within the Ruth Well tenements beneath shallow cover and to identify additional targets.

Further rock chip samples are under analysis by the ALS Global laboratory in Perth, with results pending, while the Company has completed the initial heritage survey work, allowing preparations for its maiden stratigraphic diamond drilling program at the Osborne JV to begin.

Company Comments

GreenTech Metals Executive Director Thomas Reddicliffe said that the Company is encouraged by the latest assays from the West Pilbara Lithium Projects which confirm the scale and mineralisation potential of its tenements.

“Importantly, these high- grade assays further demonstrate the prospectiveness within the 7.5km strike at our Kobe Prospect, and we are confident that further exploration and drilling will lead to more discoveries,” he said.

“We are also pleased to report that our initial heritage surveys have now been completed, allowing our maiden drilling programme to commence this quarter. Initially we are planning to complete a stratigraphic drill hole at our southern pegmatite zone to improve our technical understanding of the area.”

“In light of SQM’s proposed $1.6 billion acquisition of Azure Minerals Limited, the West Pilbara is truly cementing its position as one of the world’s premier jurisdictions for hard rock lithium exploration. GreenTech is looking forward to unlocking the true potential of its tenure in this highly prospective region.”

GRE’s Australian Stock Exchange-listed share price is currently trading at $0.38 cents (2.30pm UTC+ 8 hours).
