• Anson Resources starts construction of sample demonstration plant at the Green River lithium project in Utah
  • The project is being developed in conjunction with the 1.038Mt LCE Paradox project
  • Demonstration plant will initially produce 500kg p.a. of battery grade lithium carbonate
  • Production is expected from January 2024


Special Report: Anson Resources has commenced construction of the sample demonstration plant at its Green River lithium project in Utah, USA.

The company plans to develop the Green River project in parallel with its lead asset, the nearby 1.038Mt LCE Paradox lithium project.

Kicking off construction is another major step in Anson Resources’ (ASX:ASN) planned accelerated development of the project, and comes after a detailed geotechnical engineering study over the project confirmed the site of the proposed processing plant back in October.

When complete, the demonstration plant will continuously produce lithium carbonate (Li2CO) for use by Original Equipment Manufacturers (OEM’s) and other potential offtake partners in their qualification process.

Initial capacity of 500kg per year

Lithium carbonate will be produced using Direct Lithium Extraction (DLE) technology and will replicate equipment and process used in Anson’s Lithium Innovation Centre (LIC), Florida USA, which is producing samples for OEM and cathode active material (CAM) qualification test work.

DLE tech promises to produce cheaper, higher quality, and more environmentally friendly lithium than incumbent processes and has been used in water treatment for decades – with its use to extract lithium from brines just now coming into its own.

“The data collected from the continued operation of the Sample Demonstration Plant (SDP) at the LIC has created a deep understanding of the most advantageous production conditions and processes,” the company said.

“This knowledge has been used in the design of the demonstration plant at Green River, which will produce additional samples using the same process from fresh brine.

“The equipment used to produce these samples at Anson’s LIC will be replicated and shipped to the demonstration production site.”

The demonstration plant will showcase all the processing steps required to produce battery grade lithium carbonate at an initial production capacity of 500kg p.a.

Production expected by Jan 2024

Anson advises it has received the necessary approvals for the demonstration plant site and groundwork has already commenced.

The company has also been successful in applying for a main power connection to the site and has reached agreement for the supply of water.

It is anticipated that the Green River demonstration plant will commence production in January 2024.
