Tambourah Metals (ASX:TMB) reports 3 exploration licence applications located northeast and along strike from the Russian Jack-Haystack Well Lithium Project in the Pilbara have been granted.
The tenements have a combined area of 193km-square, covering the northeastern extent of the Bonney Downs Monzogranite and the Golden Eagle Orthogneiss, known to be associated with pegmatite-hosted occurrences of tin-tantalum and lithium.
The new tenements extend the Tambourah tenure to 70km of strike.
There has been minimal previous exploration for pegmatite-hosted LCT mineralisation within the recently granted tenements, other than a reconnaissance program of rock chip sampling in 2017 reported by Macarthur Lithium.
Macarthur Lithium collected 23 rock samples from an area of pegmatites identified from aerial photography. These samples occupy the southwestern corner of E46/1477.
The sampling covered a zone about 700m long, but the Macarthur Lithium report states that pegmatites may extend for up to 3km.
Assay results of whole rock samples did not identify anomalous lithium (maximum 41ppm), however K/Rb ratios (an indicator of fractionation) are as low as 50, suggesting a potentially fractionated suite of pegmatites and given the localised sampling pattern, are considered worthy of further investigation.
Tambourah Executive Chair Rita Brooks says the company is pleased to expand the Russian Jack Lithium Project following the recent announcement of positive rock sampling results from pegmatites at Haystack Well.
“The addition of the Kurana tenements provides significant additional opportunity across the under explored margins of the Bonney downs intrusion.”
Tambourah Metals was established in 2020 to develop critical minerals in Western Australia. It has proposed exploration Lithium drilling programs at Tambourah Gold and Lithium project and its Russian Jack Lithium project in the Pilbara.
