Standard Lithium Reports Fiscal First Quarter 2025 Results

VANCOUVER, British Columbia, May 09, 2025 (GLOBE NEWSWIRE) -- Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV:SLI) (NYSE American:SLI), a leading near-commercial lithium company, today announced its financial and operating results for the three month fiscal period ended March 31, 2025.

“2025 will be a pivotal year for us, marked by several key milestones that will shape the future of Standard Lithium, our joint venture, and impact the industry as a whole,” said David Park, Chief Executive Officer and Director of Standard Lithium. “We started with a strong first quarter by finalizing our $225 million grant from the US Department of Energy, advancing our subsurface understanding through extensive reservoir testing, completing the derisking of our DLE technology with a final pilot field test at South West Arkansas, and continuing to expand our leasehold footprint in East Texas. Together with our South West Arkansas project’s recent designation as a priority transparency critical mineral project by the Trump administration and the approval of our first brine production unit, these achievements reinforce our conviction that our projects in the Smackover will deliver significant value to our shareholders, the communities that we work in, and will help secure critical mineral production in the United States. While much remains to be done ahead of a final investment decision at SWA, as well as further advancing East Texas, we are energized by the momentum we have built and we are focused on our next project development milestones.”
