Lithium South Development Corporation announced that drilling has commenced at the Hombre Muerto North Lithium Project (HMN Li Project), Salta Province, Argentina. Servicios Gelogicos of Salta, Argentina began to turn the first hole on June 12th. The drilling method is diamond drill hole with double packer sampling at select intervals.

The 2,000 meter drill program is expected to continue for the next several months, with results reported as obtained. The program is being supervised by Dr. Mark King, a Qualified Person under National Instrument 43-101, and Principal Hydrogeologist and President of Groundwater Insight Inc. Dr. King has an extensive background in lithium brine resource and reserve estimation. The objective of the program is to potentially expand the current Lithium Carbonate Resource which is defined as 756 parts per million lithium within 571,000 tonnes in the Measured and Indicated Categories with a low magnesium to lithium ration of 2.6 to 1.0.(see news release December 4, 2018, and NI 43-101 compliant Technical Report titled "Initial Measured and Indicated Lithium and Potassium Resource Estimate, Hombre Muerto North Project, Salta and Catamarca Provinces, Argentina", prepared by independent consultants Montgomery and Associates of Santiago, Chile).

The resource is contained solely on the Tramo Claim Block, which is 383 hectares in size, and is one of five salar-located, noncontiguous claim blocks that comprise the total project area of 3,287 hectares. The drill program will focus exploration on the Alba Sabrina Claim Block, which is 2,089 hectares in size. A recent TEM Study at the Alba Sabrina Claim Block (See October 4, 2021, press release) provides potential indication of a surficial halite aquifer of approximately 75 meters of depth, with potential indication of clastic brine aquifer immediately below.

The TEM Study was limited to a depth of approximately 350 meters, 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.
