Arena Minerals Inc. reported results from its recently completed surface transient electromagnetic (TEM) survey over the Antofalla North claim block. The survey results confirm the presence of halite over the salar surface, representing approximately 15% of the claim block, but also discovered low resistivity fields at depth along the eastern margin of the survey area. This low resistivity field is interpreted as a large aquifer saturated with brine, increasing the prospective brine field by 600 percent. Arena had purchased the claim block on the assumption brine would be present only within the known halite found on the salar surface, which covers the north western corner of the property. A follow up work program has been initiated, consisting primarily of shallow drilling on a regular grid to determine brine composition over the halite dominant salar surface. Once these results have been received a drill program will be designed to define the brine resource hosted within the halite as well as test the low resistivity discovered in this survey. The TEM survey was performed by Quantec Geoscience Argentina S.A. The TEM field procedure was designed to collect sounding data in an expedient manner. Data were collected with a moving-loop method in which the receiver coil was located at the center of a square, single-turn transmit loop. Transmit loop dimensions were fixed at 200 m x 200 m. A frequency of 25 Hz and 2.5 Hz was employed throughout the survey allowing secondary magnetic field decay measurements over a total of 20 time channels. The transmitter and receiver were linked with a reference cable.
