Patagonia Lithium (ASX:PL3) is continuing to review the radiographic, magnetic, and gravity data acquired to identify sampling and potential drillhole locations at its lithium valley pegmatite and niobium REE projects.
The company’s Brazilian subsidiary, PL3 Brazil Mineracao, has been granted the concession 830.178/2024 for a three-year period, with 24 applications still pending.
The concession is located within a volcano-sedimentary association overlaying the TTG (Tonalite-Trondhjemite-Granodiorite) basement, known as the Serra Negra Group.
Patagonia says the geophysical pattern is characterised by diffuse granularity. On site chemical soil data will be collected in the field for an assessment based on medium radiographic intensity in geophysics of uranium, thorium, and potassium.
The company notes potassium is evidenced in the river systems, but is ‘highly ubiquitous’. The concession to the east of 830.178/2024 has been staked for lithium and also shows promising high anomalies.
The main geophysical data coming from georeferenced PDFs, highlighted by the correlation between samples is the F parameter, followed by the thorium-uranium ratio. There is a high correlation between Kd potassium factor and Thorium and rare earths.
Patagonia says deposit 830178 has upside for pegmatites near granite intrusions breaking through meta sediments.
Patagonia proposes exploring 830177 and 830178 with augur for soil samples. REE are at the bottom of the soil horizon.
The company intends to evaluate the acquisition of spectral data with a drone to get higher resolution from a spectral camera.
Patagonia Lithium has two major lithium brine projects – Formentera/Cilon in Salar de Jama, Jujuy province and Tomas III at Incahuasi Salar in Salta Province of northern Argentina in the declared lithium triangle.
Since listing on 31 March 2023, recharge water analysis, surface sampling and MT geophysics have been completed in preparation of an upcoming drill program at Formentera, and MT Geophysics at Tomas III that was very prospective. In July 2023 a 13-hole drill program was submitted for approval.
Samples as high as 1,100ppm lithium, as reported on 2 June 2023, were recorded at Formentera and resistivity values as low as 0.3Ω.m were recorded during the MT Geophysics survey at Formentera making the project highly prospective.
