Lithium South Development Corporation announced the completion of the first pumping well at the 2,089-hectare Alba Sabrina claim block located in Salta Province, Argentina. The Alba Sabrina claim is the largest of the five, salar located claim blocks which total 3,287-hectares of the 5,687-hectare Hombre Muerto North Lithium Project (HMN Lithium Project) package. Pumping well PW23-AS-02 has been completed to 400 meters of depth and has encountered sand layers as the dominant texture throughout.

PW23-AS-02 has been piped and graveled in preparation for long term pumping tests, with a screen length of 207 meters. State-of-the-art down the hole geophysics has been completed by Zelandez (Salta, Argentina), a provider of specialized lithium brine technology. A profile of the well was completed and provides valuable insight into the hole potential.

Test work completed by Zelandez includes the measurement of conductivity and temperature of well fluid, well caliber measurement, resistivity measurement, radioactivity measurement, ultrasonic wave measurement and nuclear magnetic resonance of sediment rock/fluid. Based on this test work, total porosity averaged 21% ranging from 1% to 45%. The Specific Yield throughout the profile averaged 7%, with maximum values of up to 33%.

Based on this information, the technical team plans to install a high-capacity pump capable of extracting brine at a rate of between 40 and 50 liters per second. Hole PW23-AS02 is in a key location and could provide substantial brine for production throughput.
