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 km2. 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.
