First Lithium Minerals Corp. announced the commencement of its exploration program on its 100% owned OCA Lithium Project in Chile and that it has contracted SouthernRock Geophysics S.A. to conduct Transient Electromagnetic (TEM) and Magneto- Telluric Surveys (MT). The OCA Lithium Project is comprised of approximately 8,900 ha of mineral exploration concessions located in the salars of Ollague, Carcote, and Ascotan in the Antofagasta Region of Northern Chile within the cordilleran sector bordering Bolivia. The principal objective of the geophysical surveys is to define the distribution of the resistivity parameters with respect to depth in the prospect areas of the project in order to characterize the conductivity-thickness of the sedimentary sequence in the corresponding salar environments. The envisioned geophysical surveys consider the acquisition of contiguous 200m coincident loop
dB/dt Transient Electromagnetics (TEM) along 500 to 1,000m spaced lines over selected exploration concessions at the Ollague, Carcote, and Ascotan project areas. TEM data acquisition is expected to be executed with a 200m square coincident loop with a 1 and/or 4Hz 50% duty cycle waveform. A total of approximately 303 TEM contiguously spaced stations planned along 30 profiles for a total of 60.6 line-km. Additionally, optional tensor broadband remote Magneto- Tellurics is contemplated to extend the resistivity information at depth if the defined signature by the TEM falls short of defining the base of the conductive sedimentary sequence. The resistivity data collected by the surveys is expected to provide better understanding of the prospects'
lithology, sediments, and brine signatures, and greatly enhance future geological modeling. The exploration program will also include completing additional geologic mapping of the project area and surface geochemical sampling.
