Southern Lithium Announces Amendment to Definitive Agreement with Millennial Lithium

VANCOUVER, Sept. 29, 2017 - Southern Lithium Corp. (TSX-V:SNL) (FSE:SL5) (OTC:SLLTF) ("Southern" or "the Company") is pleased to announced that it has executed an amendment to the formal option agreement (the “Definitive Agreement”) previously announced in a news release dated November 17, 2016, with Proyecto Pastos Grandes S.A. (“PPG S.A.”), a wholly owned subsidiary of Millennial Lithium. The amendment includes an extension to the Definitive Agreement on the payment of US$1,000,000 to PPG S.A. on or before October 1, 2017 until, on or before October 12, 2017.

The need for the amendment is a result of the company not having received drilling results for the recently completed two hole program at its Cruz Property in the Pocitos Salar Basin in Salta Province, Argentina. The company expects to report assays from the two hole program shortly.

Samples have been shipped to the lab for analyses. Sampling is being conducted in accordance with CIM guidelines and an appropriate QA/QC program to ensuring accuracy and precision of the analytical process.

PPG S.A., Millennial’s Lithium subsidiary has engaged SGS Argentina SA of Buenos Aires, Argentina as the primary analytical provider. The laboratory has extensive experience with lithium brine analyses and is certified under ISO/IEC 17025, and in SGS case, specifically for determination of lithium and potassium in liquid brines by use of ICP-OES.


About the Cruz Property

The Company has executed a formal option agreement with Proyecto Pastos Grandes S.A. (“PPG SA”), a wholly owned subsidiary of Millennial Lithium Corp. (TSX-V:ML) (FSE:A3N2) (OTCQB:MLNLF), through the option Southern Lithium can earn up to an eighty percent (80%) interest in the PPG SA’s Cruz Property in the Pocitos Salar Basin in Salta Province, Argentina.

The Cruz Property is located in South America’s Lithium Triangle (northern Chile, northwestern Argentina and southwest Bolivia). The property encompasses 9,027 hectares (22,306 acres) in the Pocitos Salar Basin in Salta Province, Argentina.

The Cruz Property is contiguous to the southern limit of the Salar del Rincón Basin, where ADY Resources Limited is extracting lithium brine, and the northern limit of the Pocitos Salar Basin, where the Cruz property is located. Both properties lie along the structural belt that hosts the important lithium resources of the region, and at the junction of a large north-south fault system and the northwest-southeast megastructure along which lies the Rincon volcano, the possible source of the lithium brine in both salar basins. The 60-kilometre long Pocitos salar basin has previously only been drill tested with a shallow 12-hole program in the 1970s by an Argentinean government agency “Direccion General de Fabricaciones Militares”. To date, this is the only confirmed exploration drilling conducted in the Pocitos basin. The hole that produced the best results is near the southeast edge of the Cruz property boundary, and averaged 417 parts per million lithium. Although these results are considered historical and have not been verified by the Company's QP, the Company considers these results relevant to the future exploration of the Cruz property.
