- Anson Resources and POSCO Holdings have received board approval for a binding agreement to develop POSCO’s Direct Lithium Extraction (“DLE”) Demonstration Plant at the Green River Lithium Project in Utah.
- POSCO to lead the project at its own expense including the design, construction and operation of its proprietary Direct Lithium Extraction (“DLE”) Demonstration Plant
- POSCO to pay ~AUD $7.2 million (USD $5.2 million) non-dilutive facilitation fee to Anson.
- The collaboration positions Green River as a potential cornerstone asset in the emerging U.S. critical minerals and battery supply chain.
- During operation of the demonstration plant, the parties will evaluate broader commercial opportunities, including potential future joint investment and strategic cooperation.
Anson Resources Limited (ASX:ASN) (Anson or the Company) is pleased to announce that both POSCO Holdings Inc. (POSCO)’s board and the Company’s board have approved the terms for a definitive Demonstration Plant Agreement (Agreement) relating to the construction and operation of a Direct Lithium Extraction (DLE) demonstration facility at the Green River Lithium Project in the Paradox Basin, Utah, USA.
The board approvals mark a significant progression from the previously announced Memorandum of Understanding (see ASX Announcement 30 June 2025), establishing a framework under which POSCO will operate its own non-commercial DLE demonstration plant designed to validate lithium extraction at continuous industrial scale.
Under the agreement POSCO committed to setting up its DLE demo-plant to extract lithium from brines produced from the Bosydaba #1 well owned by Anson at the Green River Lithium Project. POSCO will be responsible for engineering, construction, operation and maintenance of the facility, while Anson will provide access to property, infrastructure and brine supply. POSCO will pay Anson a non-dilutive facilitation fee of AUD ~$7.2 million (USD $5.2 million).
The definitive agreement is expected to be signed before the end of Q2 2026. POSCO is expected to commence operation of the demonstration plant in 2027 and complete the work in 2028.
The two companies will continue to explore potential business cooperation opportunities, including joint investment in the Project, during the operation of the demonstration plant, as outlined in the MoU Agreement, see ASX Announcement 30 June 2025.
Strategic Importance
- Demonstrates strong industry validation of Green River’s low-cost lithium potential.
- Accelerates technical de-risking through continuous demonstration-scale testing.
- Positions Green River as a key participant in the emerging U.S. domestic battery materials supply chain.
