Pumping/Production Well Installation Begins at HMN Li Project

VANCOUVER, BC, Sept. 14, 2023 /PRNewswire/ -- Lithium South Development Corporation (the "Company") (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt: OGPQ) is pleased to announce the initiation of a pumping/production well drilling campaign at the 5-claim block Hombre Muerto North Lithium Project (HMN Li Project) Salta, Argentina.

This Phase One program will include the drilling of three wells: two at Alba Sabrina (AS-WW-01-23 and AS-WW-02-23) and one at Natalia Maria (NM-WW-01-23). Notably, each well will be fitted with screen filters and blind casing.  Upon completion, long-term pumping tests will be conducted to determine brine transmissivity, including the maximum flow of each well. The results will provide key information for the upcoming Feasibility Study.

The first well, NM-WW-01-23, located at the Natalia Maria claim block, is currently being drilled to a depth of 200m.  Early results from core drilling are promising, with a lithium concentration exceeding 1,175 milligrams per liter (as announced on April 6, 2023).

Following the completion of the Natalia Maria well, the team will begin drilling two wells at the Alba Sabrina block, with depths of 400m and 200m, respectively.  The Alba Sabrina claim block is the largest in the HMN Li Project claim group, encompassing 2,089 hectares of the total 3,287-hectare salar footprint.  The upgraded project resource (September 12, 2023) delineates a resource of 927,500 tonnes of Lithium Carbonate Equivalent (LCE) within this block.

In addition to the above, Lithium South Development is reviewing technical data associated with the southern Viamonte and Norma Edit claim blocks.  These blocks are being evaluated for potential production well installation during this drilling campaign.
