GreenTech Metals (ASX: GRE) has confirmed a persistent lithium soil trend over 5.5km strike with in-fill soil samples at Kobe South target in Western Australia.
The company has undertaken an extensive infill soil sampling program comprising 1635 samples which aimed to build on the results of previously reported reconnaissance sampling undertaken in the region in 2018.
“We are pleased to see the persistence of well-defined lithium soil anomalies along strike at our Ruth Well and Osborne JV projects,” GreenTech’s Executive Director, Tom Reddicliffe, said.
“These results are supported by the discovery of additional pathfinder elements which are consistent with other anomalies associated with a nearby lithium bearing pegmatite. It is also very encouraging that the tenor of the anomalies is similar to that of other soil anomalies associated with known lithium pegmatite occurrences in other parts of our project area. These results give us considerable confidence that GreenTech can continue to make further exciting lithium discoveries within the region.”
Follow-up Soil Programme
The follow-up in-fill soil program was focused on the Ruth Well and Osborne JV tenements. The purpose of the programme was to better define lithium soil anomalies which were highlighted in historic soil samples taken in 2018 by Artemis Resources (ASX:ARV). The historic samples had been taken on a 100m x 400m N-S grid while the follow-up soil program was merged with the original grid with samples taken on a 200m x 50m grid spacing. Exploration to date has highlighted the effectiveness of soil sampling in identifying both poorly exposed and outcrop of lithium pegmatite.
Kobe South
The Kobe South Lithium soil trend is southeast trending over a strike of 5.5km and varies in width from 300m up to 1km. The trend appears to stop in the northwest while in the southeast it is truncated by the tenement boundary.
However, despite the strong and persistent lithium soil anomalism, no at surface pegmatite exposure has been identified suggesting that the structure may be recessive or poorly exposed. Kobe South is considered to likely represent a western extension to the Osborne cluster which is exposed at surface and located 3.4km to the east within the Osborne JV tenement E47/3719 (51% GRE / 49% ARV).
Next steps
These lithium soil trends are now sufficiently defined to allow initial drill testing of the higher- grade zones aimed at identifying associated pegmatite bodies. While some lithium soil trends have been partially cleared by previous heritage surveys, additional surveys are planned to ensure all targeted areas are covered.
