Infinity Mining (ASX:IMI) has restarted exploration at the South Tambourah Lithium Project in the Pilbara region of Western Australia.
The program is designed to identify further lithium-bearing pegmatite and rare earth elements (REE) with the continued field mapping and sampling of pegmatite outcrop on E45/4848 and the newly acquired adjacent tenement E45/5720.
Latest assays received from 8 rock chip samples collected in 2022 confirmed ‘high-grade’ lithium mineralisation up to 3.86% lithium oxide (Li2O), 338.5 parts per million (ppm) caesium (Cs), 174ppm niobium (Nb), 3,013.5ppm rubidium (Rb), and 233.7ppm tantalum (Ta).
Infinity reports these results occur within previously defined pegmatites and new pegmatites in the north-west area which may extend the area of lithium-bearing pegmatites targeted in the recent 2022 November drilling campaign.
Additionally, the geochemistry of rock chip samples returns ‘strongly’ elevated Cs, Nb, and Rb, which points to the highly fractioned nature of the pegmatites and their prospectivity for lithium mineralisation.
Infinity Mining Chief Executive Officer (CEO) Joe Groot says: “Infinity’s technical team and I will be back in the East Pilbara initially to build new track access through to the Brisbane Nickel Project but also to allow the roll out of the subterrain imaging program across the 4 South Tambourah tenement sub-blocks.
“This first quarter program for hidden pegmatite units as well as new surface expressions of pegmatite units will guide the second quarter drilling campaign”
In conjunction with this, we will be doing maiden ground survey work on the newly acquired South Tambourah E45/5720 which is situated adjacent to E45/4848. This first quarter program for hidden pegmatite units as well as new surface expressions of pegmatite units will guide the second quarter drilling campaign.”
The company reports Ambient Noise Tomography imaging over the 4 Tambourah sub-blocks has been commissioned and will begin in mid-March. This survey is designed to identify pegmatite development and orientation below the surface pegmatite units and to identify new pegmatite that has no surface expression.
Infinity Mining holds 100% interest in 711km-square of tenements in the Pilbara and Central Goldfields region of Western Australia, comprising 10 exploration licences, 2 mining leases, and 7 prospecting licences. The tenements are located in highly prospective gold, copper, and lithium terranes.
