Junior explorer Patriot Lithium (ASX:PAT) is looking to accelerate exploration at its Keystone and Tinton West projects in the Black Hills of South Dakota and Wyoming, US.
The $16.06 million market capitalisation company says it has begun a mapping and sampling program following its recently completed reconnaissance work, which identified areas of high prospectivity for pegmatite-hosted lithium mineralisation.
This current program will complete and extend the sampling and mapping of pegmatites identified as potentially lithium-fertile across both projects in the hopes of generating drill targets.
At Keystone, the company notes additional exploration will occur following the sampling of the previously identified and potentially lithium-bearing pegmatites. Here, Patriot hopes to identify new outcrops not evident in satellite imagery.
Exploration at Tinton will initially focus on historically identified outcrops before expanding to attempt to locate new outcrops within Patriot’s claim blocks.
Portable X-ray fluorescence (pXRF) and laser-induced breakdown spectroscopy (LIBs) measurements will be used to assess samples in the field, and a batch of samples will be submitted for analysis by SGS in Burnaby, reports Patriot.
Mapping and sampling at Keystone is scheduled for up to 4 weeks of fieldwork, followed by an additional up to 2 weeks on the Tinton West tenements, with assays expected to be received no longer than 6 weeks after being sent off to the lab.
Commenting on the exploration, Patriot Lithium Chief Executive Officer (CEO) and Managing Director Nicholas Vickery says: “We are pleased to recommence our exploration program within our prospective Black Hills portfolio following the exciting identification of potentially fertile lithium-bearing pegmatites at Keystone, only 3.5km from the historic high-grade Etta, Edison and Hugo Li mines and in the same region as Iris Metals’ Beecher project.
“This follow-up program is designed to help generate drill targets across Patriot’s Black Hills claims, particularly in areas where we have previously identified potentially Li-fertile pegmatite outcrops“
The historic Etta mine operated from 1898 to 1960, recording a head grade of up to ~6.0% Li2O, and yielded up to >14m-long spodumene crystals, believed to be the largest ever mined. This program will systematically sample and map pegmatite intrusions identified as potentially lithium-fertile across Patriot’s Keystone and Tinton West claims.
This follow-up program is designed to help generate drill targets across Patriot’s Black Hills claims, particularly in areas where we have previously identified potentially Li-fertile pegmatite outcrops.”
Patriot Lithium is a ‘high-grade’ hard rock lithium explorer focused on exploration within the Black Hills lithium district of South Dakota and Wyoming and the Pegmatite Belt of Arizona within the US.
Patriot Lithium had $5.1 million cash at hand as of 30 June 2023, according to its latest quarterly report.
