About Lithium South

Lithium South is focused on developing the Hombre Muerto North Lithium Project, located on the Hombre Muerto Salar, a major lithium-producing salar in Argentina. The property is adjacent to a US$840 million lithium mine development being undertaken by the Korean multinational corporation POSCO, which acquired the raw ground from Galaxy Resources
Ltd. for US$280 million. The Company completed a Preliminary Economic Assessment of the HMN Li Project in 2019, utilizing conventional evaporation extraction.

The Company is evaluating conventional evaporation as a process method, and Direct Lithium Extraction (DLE) as an alternative method. Three candidates for DLE are currently being evaluated. Two, 2,000-liter bulk brine samples are being evaluated outside of Argentina. One sample is being tested by Lilac Solutions of Oakland, California. A second 2,000-liter bulk sample is being tested by Chemphys Chengdu, in China. DLE test work is also currently underway in Salta, Argentina by Eon Minerals.
