First Lithium Minerals (CSE: FLM) is kicking off the new year with further exploration at its OCA lithium project, which is found in Northern Chile. The firm has indicated that it will be conducting further geophysics at its property as it works to better understand the underlying geology.
The company has begun the use of Magneto-Telluric, or MT, geophysics, which is complementary to the previously conducted Transient Electromagnetic, or TEM, surveys conducted by the company. The MT surveys will assist the company in defining the base of highly conductive intervals that were first identified by the TEM surveys.
First Lithium intends to use the surveys to further define the highly conductive horizontal zones at the OCA project, with the MT surveys expected to provide data to depths below 400 metres, which is the depth at which the TEM surveys were able to provide data to. The surveys are to be used on two northeastern prospects at the Ascotan and Carcote salars, as well as on a southern prospect of the Ollague salar.
Current plans call for a total of 60 MT sites which will be conducted on 600 metre spacing along three lines at the Ascotan salar. A further five lines will be conducted at Ollague-Carcote region. The surveys are currently slated to be completed before the end of February.

“We have already identified two priority target areas with highly conductive zones which are indicative of saline aquifers and potential mineralised brines at depth. With the follow up MT geophysical surveying we expect to further delineate promising geophysical characteristics and interpret potential bedrock depth, which will advance our geological and hydrological understanding and aid us in defining drill targets,” said CEO Rob Saltsman on the development.
The MT surveys follow the completion of TEM surveys in December, which occurred on each of the Ollague, Carcote and Ascotan salars. The surveys were said to have identified multiple low resistivity zones across several prospective areas, and First Lithium believes the zones are indicative of characteristics of mineralized saline aquifers. Carcote and Ascotan salars are said to have had the most promising results, with responses identifying two high priority conductivity targets for further exploration.
