VANCOUVER, British Columbia — Standard Lithium Ltd. has signed a term sheet with global specialty chemical company LANXESS Corporation for a contemplated joint venture in the commercial production of battery grade lithium from brine extracted from the Smackover Formation in South Arkansas.

Standard Lithium is working with LANXESS in a phased approach as per terms of a binding memorandum of understanding to develop commercial opportunities related to the production, marketing and sale of battery grade lithium products extracted from brine produced from the Smackover Formation.

Under the proposed terms of the joint venture, LANXESS would contribute lithium extraction rights and grant access to its existing infrastructure to the joint venture, and Standard Lithium would contribute existing rights and leases held in the Smackover Formation and the pilot plant being developed on the property, as well as its proprietary extraction processes including all relevant intellectual property rights.

Upon proof of concept, LANXESS is prepared to provide funding to the joint venture to allow for commercial development of the future commercial project, and it is anticipated that the joint venture will include options for Standard Lithium to participate in project funding on similar terms. The final terms of the joint venture and any funding arrangement remain subject to completion of due diligence, technical proof of concept, normal economic viability studies to confirm the technical feasibility and economic viability of the project, and the negotiation of definitive agreements between the parties.
