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.

Chilean GEODATOS has finished the TEM survey for lithium

Posted by on Saturday, 20 March, 2010

Salares Lithium Inc. reports the results of the first phase of a transient electromagnetic survey (“TEM”) completed on the northern portion of the Salar de la Isla. This salar is part of the Company’s Salares 7 project in Region III, Chile. The TEM survey was carried out by Geodatos SAIC (“Geodatos”) of Santiago, Chile, and was designed to define the size and extent of the brine pool within the salar. The majority of the world’s lithium production comes from salars, or salt lakes, where prospective lithium mineralization is generally hosted in brine horizons.
Salar de la Isla, which encompasses a total of 16,500 hectares, is approximately 15 kilometres (“km”) long and 6 km wide on average. The northern area surveyed and studied comprises approximately 10,750 hectares, which is approximately 65% of the areal extent of the salar. Using the results obtained from the 38.5 line km survey, Geodatos has constructed a three dimensional model of the distribution of the interpreted brine bearing horizon. Using a resistivity cut-off of 1 ohm/metre (interpreted by Geodatos as definite brine), Geodatos has calculated the brine bearing horizon within the northern portion of the salar to have a volume of 2.459 billion kilolitres (kilolitres are equivalent to cubic metres). Using a resistivity cut-off of 2 ohm/metres (interpreted by Geodatos as possible brines) the calculated volume of this horizon increases to 5.393 billion kilolitres.

A gravity survey is being initiated on Salar de la Isla as the TEM survey was unable to penetrate to the base of the salar which indicates that the salar has a depth in excess of 200 metres. There is potential for additional brine bearing horizons beyond where the TEM was able to penetrate to.

“We are excited about the volume calculation identified by Geodatos and the fact that it only accounts for the northern portion of one of the Company’s seven salars. The experience Geodatos represents regarding the TEM survey and the relationship of the correlation of 1 ohm/metre as definite brine with potential of brine up to 2 ohm/metre, is encouraging. The Company will now be required to drill/sample the extensive interpreted brine horizons before a porosity value and a resource calculation can be established”, commented Todd Hilditch, CEO of the Company.

The Company intends to complete an additional 13 kms of TEM survey lines on the southern portion of the salar to enable the entire salar to be modelled in a similar fashion. Further, some of the existing lines will be extended to completely investigate the lateral extent of the interpreted brine bearing horizon. In order to fast track the exploration program on the remaining six salars, the Company has instructed Geodatos to double the size of the geophysical crew.

The TEM survey lines for Las Parinas were extended beyond the boundaries of the salar on to areas covered by alluvial and / or volcanic material. The survey identified a continuous brine bearing horizon that extended up to 2.5 kms from the salar edge and underneath the adjacent rocks. The three survey lines averaged approximately 9 kms long each.

Using the results obtained from the 26.5 line km survey, Geodatos has constructed a three dimensional model of the distribution of the interpreted brine bearing horizon. This horizon extends from surface to a depth of 170 metres.

Using a resistivity cut-off of 1 ohm/metre (interpreted by Geodatos as probable brine), Geodatos has calculated the brine bearing horizon within the surveyed portion of the las Parinas to have a volume of 1.177 billion cubic metres. Using a resistivity cut-off of 2 ohm/metres (interpreted by Geodatos as possible brines) the calculated volume of this horizon increases to 4.009 billion cubic metres.

Management is very encouraged by these initial geophysical results and intends to commence the brine sampling program as soon as the relevant equipment can be secured and moved on-site. Results from additional TEM and gravity surveys will be released as interpreted and received from Geodatos.


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.
