Li3 Energy, Inc. announce the successful completion of a geophysical orientation profile on its Pocitos Property. The survey identified three unique geophysical target areas, with potential to host mineral rich (lithium, potassium magnesium etc) brine aquifers.

Five geophysical data recording stations were established at 2 kilometer intervals along a 10 kilometer long orientation line (line 74-84). Geophysical data show that the Salar is up to 550 meters deep and that three distinct areas were outlined by electrical properties that measure the ability of each area to act as an aquifer. Generally, stronger electrical responses indicate a higher probability that the area contains mineral rich brines.

Three target areas (“Target Areas 1, 2 and 3”) have been identified and prioritized as follows:

The geophysical response (resistivity averages 0.2 ohm meters) indicates that this unit has a high probability of containing mineral rich brine aquifers. NOTE: The lower the resistivity of the target unit the higher the probability that the target unit contains mineral rich brine aquifers.

The geophysical response (resistivity ranges from 0.4 to 0.6 ohm meters) is very significant and suggests this unit contains multiple thin mineral rich aquifers distributed through the unit. Notwithstanding the very encouraging diagnostic result there is insufficient data at this time to estimate a brine resource.

“The results of this geophysical orientation test are very exciting because they suggests that this method will be a valuable exploration tool for identifying mineral rich brine aquifers” reports Mr. Luis Saenz, CEO of Li3.

Geophysical Instrumentation used during the Orientation Survey:

The orientation survey was carried out by the professionals of the Applied Geophysics Group (“GEOFI”), Institute of Petroleum and Natural Reservoirs of Directorate of Technical Studies and Research, Faculty of Engineering, National University, De Cuyo Cuyo, Mendoza, Argentina.

The ARREESS Automatic Resistivity system used for the orientation survey is a state of the art resistivity system with up to 10 adjustable IP windows and 2D and 3D Resistivity tomography capabilities using multi –electrode arrays. The transmitting power is up to 300 Watts, Current is up to 2.0 Amp and the Voltage ranges from 10 to 550. The precision is rated at 0.5%. Significant features of this powerful system include a self-adapting control system, automatic ranging and calibration, automatic checking of measured value and easy interruption of the measurements for the first view of measured structures.

TEM geophysics program in the highest producing lithium country

Posted by on Wednesday, 27 January, 2010

Salares Lithium Inc.  reports the status of the first phase exploration program on its ‘Salares 7′ project in Region III, Chile. The Project encompasses 960 square km of which 394 square km are prospective for sub-surface lithium and potassium in seven salares (brine lakes).

Exploration. The first phase of the exploration programme is a 54-line kilometre Transient Electromagnetic (“TEM“) geophysical survey on the Salar de La Isla and Salar de Las Parinas. This phase is on-going with completion anticipated for early February, 2010. The TEM geophysics program will continue onto the other five salares once the survey at the Salar de La Isla and Salar de Las Parinas is completed.

The data generated by the TEM survey will define the size and extent of the brine pools within the basins and enable the individual basin profiles to be constructed. This information will be utilized in planning the sampling / drilling program expected to begin in February, 2010.

The TEM geophysics program is being carried out by Geodatos SAIC of Santiago, Chile, a well known Chilean geophysics company with broad international experience. Pertinent to the Company’s needs is that Geodatos has conducted surveys at the lithium rich Salar de Atacama, located approximately 200 kilometres north of the Project.

About TEM. TEM uses electromagnetic impulse excitation to investigate the subsurface. It is a variation of the electromagnetic method in which electric and magnetic fields are induced by transient pulses of electrical current in coils or antennas instead of by continuous current. TEM surveys have become the most popular surface EM technique used in exploration for minerals and groundwater and for environmental mapping.
