Infinity Mining has kicked off its maiden drill campaign in search of lithium at the company’s Tambourah South project in the Pilbara region of WA after positive results from rock chip sampling at the site.
The 2500m RC drill program has been designed to test the largest lithium-bearing pegmatites at the project where the depth and width of the structures will be targeted.
Previous assay results from the explorer’s rock sampling program as part of its first field work at the site in August confirmed multiple stacked lithium-bearing pegmatite units. More than 225 samples were taken in total across the western side of Tambourah South.
Sample highlights included grades of 2.635 per cent lithium oxide, 0.0662 per cent rubidium and 611.3 parts per million caesium. A total of 25 samples returned more than 1 per cent lithium oxide, with 14 returning more than 1.5 per cent lithium oxide and six results of more than 2 per cent lithium oxide.
The samples were taken from 36 weathered outcropping pegmatite units with widths of up to 10m and strike lengths of up to 558m, making up more than 2.6km of strike length in total.
Numerous pegmatite dykes hosting the lithium minerals spodumene and lepidolite were identified within the Tambourah South tenement, 80km south-west of Marble Bar in April during a helicopter-assisted reconnaissance program of several Pilbara projects.
A follow-up sampling program in September returned further positive lithium results including grades of up to 1.77 per cent lithium oxide. The most recent campaign saw 31 rock chip samples and 223 lag samples collected along the north-western boundary of Tambourah South.
Infinity says the rock chip samples were collected along previously unsampled prospective pegmatites with spodumene visually identified in several of the rock chips. In addition to the peak grade of 1.77 per cent lithium oxide, three other samples returned over 1 per cent lithium oxide.
Infinity Mining Chief Executive Officer, Joe Groot said: “The high-grade Lithium assay results from our earlier rock chip sampling programs at Tambourah South are both high-grade in nature and widespread across the western side of the tenement, giving the Company heightened confidence to proceed with our maiden RC drilling program.”
“I am looking forward to drill testing these pegmatites during November to determine the depth extent of mineralisation below the surface and then reporting the assay results over the coming months.”
Infinity has an eye on a number of commodities including gold, copper, lithium and base metals in the Pilbara region where it holds 100 per cent of its 697 square kilometres worth of tenements.
The company’s Tambourah South prospect is shaping as prospective for lithium as it sits 65km south-east of the Pilgangoora lithium deposit whilst the Wodgina lithium deposit is nearby to the north. With a solid set of sampling figures in a region known for lithium deposits, the market will be keeping a close eye on what Infinity can unearth at Tambourah South.
