Anson and POSCO partner for Utah lithium plant

Anson Resources (ASX:ASN) and South Korean industrial titan POSCO Holdings have formalised plans to develop a direct lithium extraction demonstration facility at the Green River lithium project in Utah.

The collaboration, sanctioned by the boards of both companies, establishes a binding framework for POSCO to engineer, construct, and operate the plant, utilising brine supplied from Anson’s Bosydaba #1 well.

Under the agreement, POSCO will pay a $7.2 million facilitation fee, while Anson provides the requisite infrastructure and property access.

Scheduled for commissioning in 2027, the facility aims to validate POSCO’s proprietary DLE technology at a continuous industrial scale.

The partnership follows extensive due diligence, including a 2025 bulk brine shipment to South Korea for efficiency testing and Anson’s recent "polishing" programmes designed to eliminate contaminants from its lithium chloride eluate.

Anson CEO Bruce Richardson described the venture as a "transformational step", noting that POSCO’s involvement underscores the strategic value of domestic US lithium supplies.

For Anson, the deal provides a high-level industry endorsement of Green River’s low-cost potential, while POSCO secures a critical foothold in the North American supply chain.

A definitive agreement is expected by mid-year.

At the time of reporting, Anson Resources’ share price was $0.080.
