Name of the Project
Green River project.

Utah, in the US.

Project Owner/s
Anson Resources.

Project Description
Anson plans to extract lithium and bromine from brine to produce high-purity products using direct lithium extraction technology and conventional flowsheets for all other processing.

Phase 1 is expected to produce about 13 074 t/y of lithium carbonate over a 23-year mine life.

The proposed Phase 2 expansion will target substantial expansion in the production of lithium carbonate and bromine, and will expand the project resources through the re-entry and sampling of historic wells, including Mineral Canyon; Sunburst; and high-grade, large Mississippian formations.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
Phase 1 has a pretax net present value, at a 7% discount rate, of $1.31-billion and internal rate of return of 47%, with a payback of two years.

Capital Expenditure
Capital expenditure in Phase 1 is estimated at $495-million.

Planned Start/End Date
First production of battery-grade lithium carbonate in 2025.

Latest Developments
Anson has started construction of the sample demonstration plant at its Green River lithium project – another major step in Anson's planned accelerated development of the project.

This comes after it completed a detailed geotechnical engineering study on the project area and confirmed the site of the proposed processing plant in October 2023.

The demonstration plant is located at Anson’s previously acquired industrial-use land holding at Green River, and when complete will continuously produce lithium carbonate for use by original-equipment manufacturers and other potential offtake partners in their qualification process.

Anson has received the necessary approvals for the demonstration plant site, and groundwork has started. It has also been successful in applying for a mains power connection to the site and has reached an agreement for the supply of water. It is expected that the Green River demonstration plant will start production in January 2024.

Key Contracts, Suppliers and Consultants
None stated.
