Anson Resources Ltd (ASX: ASN) and POSCO Holdings Inc. (KRX: 005490, NYSE: PKX) have approved the terms for a definitive Demonstration Plant Agreement relating to the construction and operation of a Direct Lithium Extraction (DLE) demonstration facility at Anson's Green River Lithium Project in the Paradox Basin, Utah, USA. Under the agreement, POSCO will be responsible for engineering, construction, operation, and maintenance of the DLE demonstration plant, while Anson will provide access to property, infrastructure, and brine supply. POSCO will pay Anson a facilitation fee of approximately AUD $7.2 million (USD $5.2 million). The agreement marks a significant progression from the previously announced Memorandum of Understanding, establishing a framework under which POSCO will operate its own non-commercial DLE demonstration plant designed to validate lithium extraction at continuous industrial scale. The definitive agreement is expected to be signed before the end of Q2 2026, with POSCO commencing operation of the demonstration plant in 2027 and completing the work in 2028.The two companies will continue to explore potential business cooperation opportunities, including joint investment in the Green River Lithium Project, during the operation of the demonstration plant.

The demonstration plant operation is expected to validate the commercialization of POSCO's proprietary DLE technology for the Green River Lithium Project. During the operation of the demonstration plant, the parties will discuss further commercial collaboration opportunities.
