LITHIUM SOUTH DEVELOPMENT ANTICIPATES HIGH-YIELD POTENTIAL IN PW23-AS-02 PUMPING WELL

Lithium South Development Corp. has commenced development activities for pumping well PW23-AS-02, located within the Alba Sabrina tenement. 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 metres of depth and is being prepared for a long-term pumping test.

Initial assessments suggest the well could be highly productive. Emergence, which is brine surging out of the hole, has been observed. This early indication is a promising sign for brine production potential.

The planned installation of a custom-made metal capsule, functioning as a valve to control upwelling, further underscores the anticipation of substantial brine production. Implementing this valve highlights the company's pro-active approach to managing the well's emergent behaviour, indicative of its expected high yield. A 20 HP pump set is to be deployed to a depth of approximately 58 metres, which aligns with the presence of the first filter in order to optimize brine pumpability. As the pumping operation commences, adjustments to pump capacity or depth may be made to maximize brine extraction.

"We are very pleased with our results to date and await further information from this wells performance," stated Adrian F.C. Hobkirk, founder, president and chief executive officer.

Upon long-term pump test completion of well PW23-AS-02, a pumping well is planned to be drilled on either the Viamonte or Norma Edith claim blocks south of Alba Sabrina. Continued development success and Lithium South's preliminary economic assessment financial model, published on March 4, 2024, have brought attention to the company. Management is reviewing potential industry alliances or other potential business transactions and will apprise the shareholders of any developments.

About Lithium South Development Corp.

Lithium South owns 100 per cent of the HMN lithium project located in Salta and Catamarca provinces, Argentina, in the heart of the Lithium Triangle. The Salar del Hombre Muerto has a history of lithium production, with Arcadium Lithium (Alkema and Livent merger) in operation for over 25 years, in an area just south of the HMN lithium project. The HMN lithium project is surrounded by a $4-billion (U.S.) lithium development under construction by POSCO (Korea) and the Sal de Vida project under development by Arcadium. Exploration work to date has delineated a National Instrument 43-101 compliant 1,583,200-tonne lithium carbonate equivalent (LCE) resource on the Alba Sabrina, Natalia Maria and Tramo claim blocks, three of five non-contiguous blocks that make up the HMN lithium project. A recent preliminary economic assessment announced on March 4, 2024, delineates the exciting potential of the 15,600-tonne-per-year lithium carbonate project. With pumping well installation under way, Lithium South is transitioning from being a lithium explorer to becoming a lithium developer.
