Kali Metals Ltd (ASX:KM1) has revealed a large, coherent gold-in-soil anomaly during exploration at its 100%-owned Marble Bar Lithium-Gold Project in Western Australia.
Managing director Paul Adams said: “Following our recent gold discovery at the Tiger prospect at our Marble Bar Project, the discovery of gold at surface with grades up to 4 g/t from our emerging Sherman Gold prospect is extremely encouraging.
Results along entire strike
“The gold-bearing quartz vein, up to 7 metres wide on surface, is returning positive results along the entire 120-metre strike length mapped so far.”
According to historical soil sampling data obtained during the company’s previous joint venture with SQM (NYSE:SQM) Australia, the anomaly spans a cumulative 5.1-kilometre strike length.
The standout results include rock-chip samples from the Sherman Prospect, with grades of up to 4 g/t gold recorded in a quartz vein which, as Adams outlined, extends 120 metres in length and up to 7 metres in width.
This follows earlier discoveries at the Tiger Prospect, 2 kilometres west of Sherman, where outcrop sampling identified quartz veins returning up to 3 g/t gold over a 400-by-400 metre area.
Marble Bar Project, 30 kilometres east of the old gold mining town of Marble Bar, covers 42 square kilometres within the Mount Edgar Granitic Complex and Warrawoona Greenstone Belt.
Recent exploration efforts, combining historical data with targeted rock-chip sampling, highlight the project's gold potential.
The quartz veins at Sherman are interpreted to be orogenic, featuring brecciated textures and signs of sulphidic and potassic alteration.
Additional assay results from more than 600 historical soil samples, collected during the 2021 joint venture but not previously analysed for gold, are anticipated by late December or early January.
Future campaigns in the works
These results, coupled with completed Aboriginal heritage surveys, are expected to pave the way for future drilling campaigns at the Sherman and Tiger prospects.
The discoveries validate Kali’s decision to retain full ownership of the Marble Bar Project following its renegotiation of joint venture terms with SQM Australia in October 2024.
Kali is now expanding its exploration focus to include gold alongside lithium within its Pilbara tenements.
“The gold discoveries at Tiger and Sherman reinforce the validity of the historical gold-in-soil anomalies generated from Kalamazoo’s lithium exploration in 2021,” Adams continued.
“The soils program has also identified further gold anomalism, yet to be followed up.
“These target areas have the potential to grow with additional reconnaissance and surface sampling, in addition to the results from the historical soils program which are being re-assayed for gold.
“The completed heritage surveys pave the way for a future drilling campaign at our Marble Bar gold prospects.”
