NEWS RELEASE
STANDARD LITHIUM COMPLETES SUCCESSFUL GRAVITY GEOPHYSICAL SURVEY
AT CADIZ DRY LAKE, CALIFORNIA LITHIUM PROJECT
April 19, 2018 – Vancouver, BC – Standard Lithium Ltd.(“Standard Lithium” or the “Company”)
(TSXV: SLL) (FRA: S5L) is pleased to announce that Hasbrouck Geophysics Inc. has successfully
completed a large-scale gravity geophysical survey at the Company’s Cadiz Dry Lake Project, in the
Mojave area of California. The Cadiz Dry Lake Property is located approximately 20 km southeast of
the Company’s Bristol Dry Lake Property and is currently permitted for brine extraction and
processing activities. The work has defined an infilled basin with a maximum depth of just over 700 m
beneath the Project area.
Dr. Andy Robinson, COO and President of Standard Lithium commented: " The results from this high
quality geophysical survey are very encouraging. This work has defined a closed basin with infill
deposits that are known to host lithium brines, based on preliminary sampling of extraction wells
operated by the permitted producer. Standard Lithium’s excellent relationship with the Project’s
permitted operator will allow for further exploration of the deeper basin infill deposits under the
existing permitted brine operations. This successful and rapid acquisition of high quality gravity
survey data from our Cadiz Dry Lake Project will be used to plan additional resource assessment work
at Cadiz for the remainder of 2018."
Hasbrouck Geophysics, Prescott, AZ collected gravity readings from 89 new stations, integrated 85
public domain gravity stations, and integrated data over approximately 211 km 2. The new stations
were spaced at 1 km intervals along 17 east-west lines spaced 700-800 m apart. The integrated gravity
model defined a basin-shaped depression that underlies the approximately 11,840 acres of placer and
patented mineral claims. The basin underlying the claims is steep-sided, consistent with the basin
being fault-bounded, and similar in nature to Standard Lithium’s nearby Bristol Dry Lake Project.
Repeat readings of new stations ranged between 0.014 and 0.027 mGals, while the spread for base
readings (both field and absolute) is between 0.009 and 0.015 mGals, demonstrating that the data are
of excellent quality.
The well-defined gravity trough and deeper basin indicate potential for structurally concentrated
lithium brines at depth. The survey results will be used to plan further exploration, which will include
additional geophysical surveys to identify Li-brine bearing zones and structural control. For further

dated September 13, 2016, compiled in accordance with NI 43-101 guidelines on Sedar.com.
