LSC Lithium Announces Update on Its Rio Grande Project

LSC Lithium Corporation

 (“

LSC

” or together with its subsidiaries, the “

Company

”) (TSXV:LSC) is pleased to announce that it has received completed and positive seismic tomography results from its Rio Grande project in Argentina’s Puna region.

HIGHLIGHTS

• Five seismic lines totalling 41.73 line km were completed, three lines orientated in N-S direction and two lines orientated in E-W direction.
• Wide spaced survey interpreted the previous expectations of depth extensions of the basin up to 500 m below the salar surface.
• Interpreted tomography results suggest the occurrence of lithologies suitable for the hosting of brine at depth.
• Deep targets identified for follow-up core drilling to sample brine and to determine the host lithologies’ porosity.  Drilling to commence in the near-term.
• LSC controls 26,865 ha in the Rio Grande Salar covering 90% of the salar surface.
• Previously announced Inferred Mineral Resource of 2,190,000 tonnes LCE1 down to the first 100 m. The top 50 m amounting to 1,375,435 tonnes grading at 338mg/l Li and the lower 50 m to 100 m amounting to 814,582 tonnes grading at 410mg/l Li.
• Indications of an increasing lithium grade at depth.2

LSC’s President and CEO Ian Stalker, noted, “LSC is excited to announce these results from its Rio Grande project, one of LSC’s major development projects. These survey results underscore the previous CS-AMT results from Rio Grande and interprets the expected depth of the Rio Grande basin, as well as the occurrence of potential brine hosting lithologies at depth. Deep targets have been identified for follow up core drilling to sample the deeper brine targets and to determine the host lithologies’ porosity.

The depth extension of the Rio Grande basin now has the potential to significantly increase the Inferred Mineral Resource previously announced by LSC below the 100 m depth of the current Mineral Resource. Planning is already underway to start with the deep drilling as soon as possible to advance the Rio Grande project even further.”
