Lithium South Development Corporation Drill Program to Expand Resource

Vancouver, BC – April 27, 2021 – Lithium South Development Corporation (the “Company”) (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt OGPQ) is pleased announce it is moving ahead with plans to potentially expand the current lithium resource at the Hombre Muerto North Lithium Project (HMN Li Project), located in Salta Province, Argentina.


The 3,287-hectare project is comprised of five separate areas located in the northern portion of the salar. The current resource of 571,000 tonnes of lithium carbonate equivalent is located on the 383-hectare Tramo Claim.  The resource was detailed in a National Instrument 43-101 compliant report filed December 4th, 2018 titled, Initial Measured Lithium and Potassium Resource Estimate Hombre Muerto North Project, Salta and Catamarca Provinces, Argentina, authored by independent consultants Montgomery and Associates, is summarized below:


Table 1. Hombre Muerto North Lithium Brine Resource Statement


Tonnages are rounded off to the nearest 1,000. Cutoff grade: 500 mg/L lithium, but no laboratory results were less than the cutoff grade. The conversion used to calculate the equivalents from their metal ions is based on the molar weight for the elements added to generate the equivalent. The equations are Li x 5.3228 = lithium carbonate equivalent and K x 1.907 = potassium chloride equivalent. The reader is cautioned that mineral resources are not mineral reserves and do not have demonstrated economic viability.


After technical review, management believes the current identified resource has excellent potential to be expanded.  To accomplish this, the Gaston Enrique, Natalia Maria and Alba Sabrina claims will be sited for drill programs.  The Company has located a service provider who has a drill rig located on the salar near the Alba Sabrina claim block and is negotiating a drill contract.  The Gaston Enrique claim block is located on the Catamarca side of the Hombre Muerto salar, and is the oldest claim located within the dual jurisdiction area. Management believes an Environmental Impact Report and drill permits can be obtained for this project area, which is located approximately 100 meters north of a drill hole recently completed by POSCO.  A recent corporate video of the HMN Li Project can be viewed at the Company website at


The project area under purchase option to the Company is situated contiguous to significant lithium development. Korean giant POSCO are moving ahead with plans to construct a 25,000 tonne per year conventional lithium extraction operation contiguous to the Company area. The recently announced 4-billion-dollar merger between Galaxy Resources and Orocobre will likely see further development of the Galaxy owned portion further to the south.
