Standard Lithium Ltd. : Standard Lithium Commences CSAMT/MT Geophysical Survey at Bristol Lake, Mojave Project, California

VANCOUVER, British Columbia, June 29, 2017 (GLOBE NEWSWIRE) -- Standard Lithium Ltd. ("Standard Lithium" or the "Company") (TSXV:SLL) (FRA:S5L) (OTCQX:STLHF) is pleased to announce that it has commenced a detailed and large-scale Controlled-Source Audio-Magnetotellurics / Magnetotellurics (CSAMT/MT) geophysical survey at the Company's Bristol Lake Project, in the Mojave area of California.  The survey is being conducted in order to help better define the extent of highly conductive brine resources in the deep infilled basin that underlies SLL's Project area (brine-bearing basin is up to 1.2 km thick beneath the Project area, as revealed by recent gravity survey work; see news release dated 5th June).  The survey is being completed on Standard's extensive 16,000+ acre landholding in the Bristol Lake basin, and will also be extended onto adjacent brine-producing properties in the basin, thanks to the kind cooperation of our neighbours.

Standard Lithium has retained Hasbrouck Geophysics to perform data acquisition and interpretation.  Hasbrouck are ideally suited to performing the work as they have extensive experience conducting geophysical surveys in many brine-bearing basins across the southwestern US.  Hasbrouck and their team have mobilised to site and expect that data acquisition should take approximately 2 weeks to complete given the detailed nature of the survey and the large size of the resource area, and that initial interpretation should be available for Standard's technical team to assess in the second half of July.  Results from the CSAMT/MT survey will also be used to help scope and determine locations for the next phases of Standard's resource assessment program for the Bristol Lake Project.

Dr. Andy Robinson, COO and President of Standard Lithium, commented: "We're delighted to be partnering with Hasbrouck Geophysics as they bring their breadth of exploration geophysical knowledge to bear on our Bristol Lake Project.  Our team has completed several previous surveys with Hasbrouck and we look forward to seeing their interpretation of the lateral and vertical extent of the brine deposits that are present beneath our Project area.  Results from this phase of work will be very helpful in determining final locations for a proposed drilling programme that will take place in the second half of 2017."
