VANCOUVER, BC, March 30, 2023 /PRNewswire/ — A Lithium Sud Development Company (the “Company”) (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt OGPQ) is pleased to announce the completion of NM01, the last well in the current resource expansion program at the Hombre lithium project Muerto North, Salta Province, Argentina.

The well is located in the Natalia Maria concession block, an area of ​​115 hectares strategically located in the salar. Drilling at NM01 intersected interbedded sediments containing brine and fractured halite from surface to a depth of approximately 200 meters. Below, to the final hole depth of 375 meters, the halite has a lower permeability. Nine packer samples were taken between 24 and 189 meters, with a density range of 1.215 to 1.218 g/mL and a conductivity range of 196.3 to 209.5 mS/cm. Samples will be sent to Alex Stewart Laboratories (ISO certified Mendoza, Argentina) for analysis.

A monitoring well will be installed to test the upper, more permeable blast. A separate shallow well will be installed on the same pad to test the shallow interlayer sediments. The purpose of the monitoring wells is to provide a preliminary indication as to whether the claimed block will support one or more shallow pumping wells for possible future lithium production.

The 2022-2023 resource expansion program includes a total of eight main wells, seven of which were drilled in the Alba Sabrina concession block, the project’s largest at 2,089 hectares. Combined with the just completed NM01 hole in the Natalia Maria concession block and the 2018 drilling program on the 383 hectare concession section, over 75% of the concessions located in the salar have already been tested.

A new updated lithium carbonate equivalent resource will be calculated under the supervision of Groundwater Insight of Halifax, Nova Scotia, Canada. Management plans to significantly increase the current LCE resource of 571,000 tonnes identified in the section claim block in 2018 (press release dated October 2, 2018). The intention to expand the current resource is to increase the potential project size of the operation by 5,000 tonnes per year defined in the 2019 Preliminary Economic Assessment (filed August 12, 2019).

The company’s President and CEO, Adrian FC Hobkirk, said, “We are delighted to have completed the 2022-2023 Resource Expansion Program on the HMN Li project. We look forward to the full results and the delineation of a new lithium resource.
