NEWS RELEASE

STANDARD LITHIUM SIGNS AGREEMENT TO SECURE LITHIUM RIGHTS WITH

PERMITTED BRINE PRODUCER AT BRISTOL LAKE, MOJAVE, CALIFORNIA

May 4th, 2017 – Vancouver, BC – Standard Lithium Ltd. (“Standard Lithium” or the “Company”)

(TSXV: SLL) (FRA: S5L) is pleased to announce today that its wholly owned subsidiary, California

Lithium Ltd, has signed a definitive agreement (the “Agreement”) with National Chloride Company of

America (“National Chloride”), a private California company, whereby National Chloride will grant

Standard the option to conduct lithium exploration, development and production activities, in

accordance with existing longstanding Federal and State mining permits and claims held by National

Chloride in California.

National Chloride’s Bristol Lake placer mineral claims cover approximately 12,600 acres and lie

adjacent and contiguous to Standard Lithium’s recently acquired 4,000+ acre Mojave Lithium Project.

In addition, as part of the Agreement, Standard Lithium has an option to lease access to approximately

3,000+ acres of private land held on Bristol Lake by N ational Chloride and its affiliates. Standard

Lithium’s combined property l ies on Bristol Lake playa in the Mojave Desert of southeastern San

Bernardino County, California.

National Chloride and others have mined the near-surface brines to produce concentrated chloride

products for various industrial applications for close to 100 years and as a result the area has excellent

mining infrastructure. There is electric power and water on the property. A major paved road crosses

the western edge of the property. There is a rail siding within 5 km, as well. The property is situated

approximately 200 km from Las Vegas, and 330 km of the port of Los Angeles.

Working with National Chloride, an experienced and established operator, should reduce and or

eliminate much of the initial permitting requirements that most explorers face. This strategic

relationship will allow the Company immediate access to conduct exploration brine sampling and

extraction, evaporation and processing activities.

Mr. Robert Mintak, CEO and Director of Standard Lithium commented “This transaction represents

the first step in executing the Company's development strategy o f maximizing opportunity w hile

minimizing risk and unlocking and creating value from resources the industry h as never considered

before.” Mr. Mintak added “This is the first stage of our plan of building a large domestic resource of

lithium assets that we feel will receive a premium valuation for strategic buyers because of lower

political risk and costs.”

The dry salt lake playa covers a total area of 155 km2, and hosts a geologically recent volcanic centre,

similar to other productive lithium brine playas. S tandard Lithium’s geophysics team has recently

concluded an extensive gravity s urvey o ver the entire basin, and initial interpretation of the data

suggests that the basin is deep and extensive. Historical drilling and sampling to total depths of

approximately 5 00 ft has produced brine samples with significant lithium values. F or further

information on the Mojave project please see Standard Lithium’s Technical Report compiled in

accordance with National Instrument 43-101 dated September 15, 2016 and available under the

Company’s profile on SEDAR (www.sedar.com).
