NEWPORT BEACH, CALIFORNIA / ACCESS Newswire / December 16, 2025 / Anson Resources Limited (ASX:ASN) ("Anson" or the "Company") provides the following update on the ongoing cooperation with POSCO Holdings Inc. ("POSCO"), announced 30 June 2025, regarding the development of a DLE Demonstration Plant at its Green River Lithium Project in Utah, USA.
Anson and POSCO continue to make positive progress across all workstreams for the planned demonstration plant. Over the past several months:
Multiple POSCO engineering teams have conducted site visits to Green River, undertaking detailed technical assessments and reviewing site and local infrastructure, brine supply, and development pathways.
Anson and POSCO representatives have held constructive meetings including visits by senior management to South Korea and the U.S.A, advancing technical, commercial, and operational discussions and further aligning both parties on development objectives.
These interactions have strengthened the cooperation between the companies and have contributed meaningfully to POSCO's ongoing due diligence and internal evaluation process.
POSCO Holdings is progressing its due diligence and internal review associated with the planned demonstration plant investment. Due to the ongoing completion of basic engineering studies, the anticipated finalisation date for this review has been shifted from December 2025 to Q1 2026. Anson is continuing site preparations and to engage with local suppliers and the schedule to break ground remains on track.
The Green River demonstration plant investment is part of POSCO Group's secondary battery materials strategy, which centres on securing North American lithium resources and advancing future technological competitiveness.
Based on the successful operation of the U.S. demonstration plant, POSCO Holdings plans to bring its independently developed DLE technology to market and accelerate investment and commercialization efforts for untapped lithium brine resources across North America.
The Green River DLE demonstration plant represents a major strategic investment by POSCO Group as it works to lead in securing future-critical technologies essential to the growth of its lithium business in North America.
Anson looks forward to providing further updates as the collaboration advances.
