Vancouver, British Columbia--(Newsfile Corp. - May 31, 2019) - Millennial Lithium Corp. (TSXV: ML) (FSE: A3N2) (OTCQX: MLNLF) ("Millennial" or the "Company") is pleased to announce the filing of a technical report (the "Resource Report") titled "Phase III Measured, Indicated and Inferred Lithium and Potassium Resource Estimate Pastos Grandes Project Salta Province, Argentina" dated effective May 31, 2019 that contains an updated resource estimate for the Company's Pastos Grandes lithium brine project located in Salta, Argentina.

Millennial engaged Montgomery & Associates Consultores Limitada ("Montgomery") based in Santiago, Chile, a subsidiary of international hydrogeology firm E.L. Montgomery & Associates, to prepare the independent Resource Report.

The updated resource estimate contained in the Resource Report was first disclosed by the Company in a news release dated April 17, 2019.

The Resource Report advances the Company's understanding of the Pastos Grandes Project and was a necessary step in completing a feasibility study (the "Feasibility Study") which will evaluate the economics of the Pastos Grandes Project. This Feasibility Study, which is being completed by WorleyParsons, is anticipated to be completed shortly in July, 2019.

The resource statement contained in the Resource Report, detailed in the table below, includes 4,120,000 tonnes of lithium carbonate ("Li2CO3") equivalent (LCE) and 15,342,000 tonnes of potash ("KCl") equivalent in the Measured and Indicated Resource categories, with an additional 798,000 tonnes of Li2CO3 and 2,973,000 tonnes KCl in the Inferred Resource category.
