LITHIUM SOUTH DRILLS MONITORING WELLS ON TRAMO PROPERTY

Lithium South Development Corp. has provided final results for the recently completed resource expansion drilling program at the 5,687-hectare Hombre Muerto North (HMN) lithium project in Salta province, Argentina. The program comprised eight core holes, seven located on the Alba Sabrina claim block (2089 hectares) and one on the Natalia Maria claim block (115 hectares). Combined with the previously drilled Tramo claim block (383 hectares) the company has now evaluated 70 per cent of the owned salar surface area.

Management is pleased with the excellent results from all holes. The Alba Sabrina drill program returned an average lithium concentration of 692 milligrams/litre lithium. The Natalia Maria core hole returned an average of 1,176 mg/litre lithium. The program was completed under the supervision of Dr. Mark King, qualified person of Groundwater Insight of Halifax, N.S. Lithium assay work was completed by Alex Stewart Laboratories (ISO certified) of Mendoza, Argentina. Additionally, core samples have been submitted to GeoSystems Analysis Inc. in Tucson, Ariz., for porosity analysis and results are expected in the next few weeks.

Lithium South Development is currently drilling five shallow monitoring wells on the Tramo property, to monitor groundwater levels in the salar and to support future pumping tests. The monitoring wells are located on the corners of the property. Three have been completed to date, and the remaining wells will be completed by the third week of May.

The company also plans to drill three pumping wells, two in Alba Sabrina and one in Natalia Maria, and conduct pumping tests at each well. Drilling is expected to begin in early June and completion of the pumping test program is anticipated in late August. The data obtained from the pumping tests will be used to assess hydrogeological parameters within the salar and to support future reserve estimation.

Lithium South Development is committed to responsible and sustainable exploration and development. The company is planning a third exploration campaign to drill Gaston Enrique, Via Monte and Norma Edith.

The company is pleased with the progress achieved so far. With the Hombre Muerto North deposit yielding impressive results, Lithium South Development looks forward to further expanding its resource estimation and cementing its position as a leading lithium exploration company in the region.

About Lithium South Development Corp.

Lithium South (LIS) owns 100 per cent of the Hombre Muerto North lithium project located in Salta province, Argentina, the heart of the lithium triangle. The Hombre Muerto salar has a history of lithium production with Livent Corp. in operation for over 25 years just south of the HMN Li project. The HMN Li project is surrounded by a $4-billion (U.S.) lithium development under way by POSCO (Korea) and the Sal de Vida project under development by Allkem. Lithium South has delineated a National Instrument 43-101 lithium carbonate equivalent (LCE) resource on the Tramo claim block, one of five non-contiguous blocks that make up the HMN Li project. Recent drilling on the Alba Sabrina and Natalia Maria claim blocks has identified additional lithium zones that will allow a new and potentially larger LCE resource to be defined. Lithium South is now transitioning from being a lithium explorer to becoming a lithium developer.
