Standard Lithium Signs MoU to Expand California Project With Permitted Brine Producer in Bristol Dry Lake, Adds Additional Project at Cadiz Dry Lake

VANCOUVER, British Columbia, Oct. 30, 2017 (GLOBE NEWSWIRE) -- Standard Lithium Ltd.("Standard Lithium" or the "Company") (TSX-V:SLL) (FRA:S5L) (OTCQX:STLHF) is pleased to announce that it has entered into a Memorandum of Understanding ("MoU"), with TETRA Technologies, Inc., a NYSE-listed company ("TETRA") to secure access to additional operating and permitted land consisting of approximately 12,100 acres in Bristol Dry Lake, and up to 11,840 acres in the adjacent Cadiz Dry Lake, Mojave Desert, California.  As a result, the Company now has access to approximately 48,000 acres of mixed private, patented and placer claim land in the Bristol Dry Lake and Cadiz Dry Lake basins that allows for exclusive lithium brine exploration and processing.  The new MoU with TETRA allows for the exclusive right to negotiate and conduct exploration activities and to enter into a mineral lease to allow exploration and production activities for lithium extraction on property held under longstanding mining claims and permits by TETRA (transaction terms described below). In connection with the entering into of the MoU, and in support of the transaction with TETRA, the Company has made a non-refundable deposit of US$100,000.

Standard Lithium CEO, Robert Mintak said, "Since day one we have recognized the bigger opportunity with respect to expanding the resource base and strengthening project economics at Bristol Dry Lake by securing the rights for lithium development over the entire basin.  By inking an agreement with TETRA, the only other permitted operator in the area, we have now effectively achieved that.  This is a significant and strategic move for Standard, but has only been made possible by the excellent relationships we have developed with the permitted brine operators in the region.  Gaining access to the adjacent Cadiz Dry Lake operating project is an additional benefit to our relationship with TETRA."

TETRA currently operates two passive solar evaporation plants in the Mojave Desert area of San Bernardino County, California, which produce liquid calcium chloride from underground brine reserves that are pumped to the surface.  The Bristol Dry Lake project is currently permitted for brine extraction and processing activities, has significant production infrastructure in place and is serviced by major highways, power and a dedicated rail siding and loading spur.  The Cadiz Dry Lake Property is located approximately 20 km southeast of the Bristol Dry Lake Property and brings the Company's total project opportunity in the Mojave Desert to approximately 48,000 acres.
