What is the deal between Anson Resources (ASX:ASN) and POSCO Holdings?

Anson Resources and South Korean industrial giant POSCO have agreed to build a direct lithium extraction (DLE) demonstration plant at the Green River project in Utah.

How much is POSCO paying Anson Resources (ASX:ASN) for this partnership?

POSCO is paying Anson Resources a $7.2 million facilitation fee as part of the binding agreement. In exchange, Anson grants POSCO access to its property and brine from the Bosydaba #1 well.

What is Direct Lithium Extraction (DLE) and why does it matter for this project?

DLE is a technology used to pull lithium directly from brine water more efficiently and sustainably than traditional evaporation ponds. For the Green River project, validating POSCO’s proprietary DLE technology is crucial for proving the site's commercial viability.

When will the Green River lithium demonstration plant start operating?

The demonstration plant is scheduled for commissioning and the start of operations in 2027. This timeline follows several years of due diligence, including bulk brine shipments sent to South Korea in 2025.

Why is this deal considered "transformational" for Anson Resources (ASX:ASN)?

The partnership acts as a major industry endorsement, as a global tier-one player like POSCO is committing capital and technology to the project. It validates the technical quality of the Green River brine and shifts Anson from an explorer toward a potential producer with a world-class partner.

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.
