Anson Resources and POSCO Holdings have signed a non-binding memorandum of understanding (MoU) to collaborate on the development of a direct lithium extraction (DLE) demonstration plant.

“This MoU agreement with POSCO Holdings represents another significant milestone in our commercialisation strategy and underscores the progress Anson has made in de-risking the Green River lithium project,” Anson executive chairman and chief executive officer Bruce Richardson said.

POSCO Holdings will lead the construction of the plant at the Green River lithium project in Utah’s Paradox Basin and has commenced a detailed review of the site.

The South Korean company intends to fully fund the demonstration facility, including infrastructure, operating expenses and site leasing.

Final investment decisions will follow the completion of due diligence and internal assessments, which are expected to be concluded by December 2025.

POSCO and Anson also plan to explore broader partnership opportunities, including potential joint investment in the Green River project pending the outcomes of feasibility studies.

Richardson said the partnership reflects growing global recognition of Green River’s potential.

“POSCO Holdings is a world-class chemicals producer with deep operational experience, and their interest further validates the quality and strategic potential of the project,” he said.

POSCO brings extensive expertise in lithium extraction to the collaboration, supported by years of research and development across brine and geothermal brine resources.

The demonstration plant will replicate the intended commercial operation at scale, operating continuously to produce significant product quantities and validate the industrial process.
