April 26, 2022 / Vancouver, BC / Lithium South Development Corporation (the “Company”) (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt: OGPQ) is pleased to announce the initiation of a resource expansion drill program at the Hombre Muerto North Lithium Project (HMN Li Project), Salta, Argentina.

The Company has retained Servicios Geologicos of Salta, Argentina, to conduct a 2,000-meter core hole drill program on the Alba Sabrina claim block.  At 2,089 hectares, the Alba Sabrina claim block is the largest of the nine block, 5,687-hectare project.  A recent TEM Study (See October 4, 2021, press release) has identified a surficial halite aquifer of approximately 75 meters of depth, with a clastic brine aquifer immediately below.  The TEM Study was limited to approximately 350 meters of depth, with the basement rock not confirmed.  The drill program will attempt to drill to basement, limited to approximately 700 meters by the depth potential of the drill rig.  The drill rig is expected to be located on site within the next two weeks.

Company President, Adrian F. C. Hobkirk is quoted, “We are excited to begin the potential expansion of the high-quality lithium brine resource at the HMN Li Project.  In particular, to confirm our expectations that deeper drilling will return significant results.”
