Tambourah Metals unearths lithium-bearing pegmatites and increases lithium grades at Russian Jack Project, WA

Critical minerals developer Tambourah Metals (ASX:TMB) has identified lithium-bearing pegmatites following a rock chip sampling program completed in September last year at its Russian Jack Project in Western Australia. 

The company, which has a $16.73 million market capitalisation, says these pegmatites have been located about 1km from the previously reported sampling. As a result, Tambourah announces its proposed heritage survey will be expanded to include these new areas. 

Tambourah reports rock chips also indicate lithium (Li) grades over 1% Li. These sampling results are expected to be delivered to the Commonwealth Scientific and Industrial Research Organisation (CSIRO) as part of a collaboration to use machine learning and exploration data to cover large areas of potential lithium exploration. 

Tambourah notes the discovery of these latest pegmatites comes following the identification of ‘significant’ swarms of possible lithium-caesium-tantalum (LCT) pegmatites at Russian Jack, bringing the total area of the project hosting pegmatite swarms to 380km-square.  

Meanwhile, the company also notes it is continuing its focus on accelerated exploration for LCT pegmatites at its newly acquired prospects, including the Haystack Well Lithium Project. 

Addressing the increase in grade, Tambourah Metals Chairperson Rita Brooks says: “We are working within a large area that hosts untested pegmatites and, with the use of hyperspectral data in collaboration with CSIRO, can assist with plans to drill test areas using the results of machine learning and apply this process to other geological regions. 

We are working within a large area that hosts untested pegmatites”

This will assist in the identification of priority areas to investigate. We are now planning heritage surveys working with the Palyku group to clear priority areas, and the company will subsequently apply for Program of Work (POW).”

Tambourah Metals is an explorer and developer working to develop critical minerals projects for a decarbonised future. The company’s primary objective is the rapid exploration and development of its flagship namesake gold and lithium project in the Pilbara. 

The Russian Jack Lithium project is located about 295km southeast of the township of Port Hedland in Western Australia and comprises 5 exploration licences and 3 applications. 

Tambourah Metals had $3.2 million cash at hand as of 31 March 2023, as stated in its latest quarterly report.
