CENTURY LITHIUM FILES TECHNICAL REPORT ON THE FEASIBILITY STUDY OF THE CLAYTON VALLEY LITHIUM PROJECT, NEVADA
Century Lithium has filed the NI 43-101 Technical Report for its Clayton Valley Lithium Project in Nevada, effective April 29, 2024. Prepared by Wood Canada , Global Resource Engineering, and WSP USA, the study supports the company's April 29, 2024 news release. The project boasts a 17.2% Internal Rate of Return (IRR) and a $3.16 billion Net Present Value (NPV) at a base case lithium carbonate price of $24,000/tonne. The resource estimates include 1,138.59 million tonnes of measured and indicated resources with an average grade of 966 ppm lithium, and proven and probable reserves of 287.65 million tonnes with an average grade of 1,149 ppm lithium. The project, which has a 40-year mine life, uses innovative chloride leaching and direct lithium extraction processes.
- Filed NI 43-101 Technical Report validates the Clayton Valley Lithium Project.
- 17.2% Internal Rate of Return (IRR) is economically attractive.
- $3.16 billion Net Present Value (NPV) indicates strong future cash flows.
- Proven and probable reserves of 287.65 Mt with 1,149 ppm lithium.
- Mine life of 40 years ensures long-term operations.
- Innovative extraction methods may enhance lithium recovery.
- No significant changes in economic analysis despite report updates.
- High operating costs with $40.9/t for processing.
- Mining cut-off grade of 900 ppm is substantially higher than break-even cut-off.
- Dependence on a $24,000/tonne lithium carbonate price for favorable projections.
"Century Lithium is pleased to file the report on the Feasibility Study of our Clayton Valley Lithium Project," said Bill Willoughby, President, and CEO. "The Report is the culmination of the dedicated work of our team of employees and consultants and highlights the economic benefits of the Project made possible by Century's unique use of chlor-alkali and direct lithium extraction processing. The filing of the report now marks another major milestone for the Company."
During the preparation of the Report, minor changes were made to the parameters used to determine the Mineral Resource and Reserve Estimates. The resulting economic analysis is effectively unchanged. Using a base case price of
The Mineral Resource and Reserve Estimates for the Project were updated for the Report and built using geologic data and 1,318 lithium assays from 45 core holes drilled between 2017 and 2022 and have an effective date of April 29, 2024. The constrained Measured and Indicated Resource Estimate is 1,138.59 million tonnes (Mt) with an average grade of 966 parts per million (ppm) lithium and contains 1.099 Mt of lithium or 5.852 Mt of lithium carbonate equivalent (LCE). The Proven and Probable Mineral Reserve Estimate was derived from the constrained Mineral Resources and contains 287.65 Mt with an average grade of 1,149 ppm lithium and contains 0.330 Mt of lithium or 1.759 Mt of LCE.

Century's Project centers on the mining and processing of a large, flat-lying lithium claystone deposit. Mineral Reserves are sufficient to support a mine life of approximately 40 years.
Mining is by mechanized surface excavation of claystone at production rates of 7,500 to 22,500 tonnes/day of mill feed, and 13,000 to 39,000 tonnes/year of lithium carbonate. Lithium recovery is through Century's patent-pending process that combines chloride leaching with direct lithium extraction to produce a marketable battery-quality product at the Project site.
The Report is available on SEDAR+ and on the Company's website.
