Pursuit Minerals’ (ASX: PUR) Controlled Source Audio Magneto Telluric (CSAMT) Geophysical survey by Quantec Geosciences Argentina at the Rio Grande Sur Project in Salta, Argentina which has yielded significant results identifying multiple resistivity layers considered highly prospective for Lithium enriched brines.
The results of the CSAMT survey have continued in line with our expectations that the Rio Grande Sur Project has potential to host a significant resource of Lithium brine which now extends to the Mito tenement,” Managing Director and CEO, Aaron Revelle, said.
“The CSAMT data has outlined multiple low resistivity (high conductivity) layers from approximately 150m to 500m in depth at the Mito tenement. These layers are below the current Canadian National Instrument 43-101 (NI43- 101) Inferred Resource drilling which extended to 100m.
“The data additionally suggests that the area is conductive and could yield similar results to a company which drilled ~2km to the north-east of the Mito tenement off the Rio Grande Salar and yielded exceptionally high grades averaging 773mg/Li with several samples returning in excess of 850mg/Li from ~300m below the surface.”
The Rio Grande Salar hosts an Inferred Resource of 2.1 million tonnes LCE at an average grade of 370mg/Li to a depth of 100m reported as part of an existing NI43-101 report.
CSAMT surveys have identified interpreted brines to a depth of 500m, and planned drilling to this depth is expected to significantly increase the resource. A portion of Pursuit’s Rio Grande Sur tenements (~3,000ha) cover a section of this resource.
Pursuit holds five tenements collectively known as the Rio Grande Sur Project that are prospective for lithium located west of Salta, Argentina. The five tenements cover approximately 9,233 hectares.
