Greentech Return Assays Up to 3.6% Lithium at Osborne JV

24 July 2023 14:22

The potential of Greentech Metals West Pilbara portfolio continues to skyrocket, with the latest rockchip sampling results from the explorers Osborne joint venture in Western Australia uncovering a new high-grade pegmatite trend showing assays up to 3.6 per cent Li2O.

Pegmatite Potential

A total of thirty samples were collected from across Osborne, with seven samples returning positive results for lithium, two of which showed assays exceeding one per cent Li20 and resulted in the identification of the newly christened Southern Pegmatite Trend.

Significant assays from the program include:

o 3.6% Li2O (Sample No 23CR038)
o 2.3% Li2O (Sample No 23CR039)
o 0.55% Li2O (Sample No 23CR044)
o 0.48% Li2O (Sample No 23CR045)

The two high-grade samples of 3.6% Li2O and 2.3% Li2O have now been submitted for further XRD analysis to confirm lithium mineralogy.

Ground reconnaissance of this new pegmatite zone has confirmed that it is separate from the known Kobe trend which is primarily located within the Company’s adjacent Ruth Well Project but extends on to Osborne tenue, with previous rock chips samples taken from the Kobe trend showing grades up to 1.8 Li2O.

Chipping In

In response to the newly identified trend, Greentech has now commenced an extensive review of historic datasets to potentially grow the pegmatite potential of the border Ruth Well and Osborne Project areas, with this program aimed to potentially discover additional lithium trends and identify extensions to known trends.

The Company is now also mobilising its field team to Osborne for further exploration ahead of a maiden drilling campaign later this year, with mapping, ground reconnaissance rock chip sampling soil sampling and drill target identification planned in anticipation of drilling.

The Company said it has begun preparations relating to regulatory requirements for drilling, having submitted multiple programs of work already.

“Initial assays from this new lithium pegmatite trend indicate a potentially higher grade lithium trend than our original discovery, and highlights the potential to discover further lithium pegmatite zones within the existing tenement package,” Executive Director Thomas Reddicliffe.

“GreenTech has established a great foundation in this growing lithium province in the West Pilbara and these latest results further reinforce our belief that there is significant lithium pegmatite potential on our tenements.”
