Cypress Development (CYP) has made further strides in its scoping-level study of chloride-based leaching to recover lithium from claystone.
The work is taking place at the company’s Clayton Valley Lithium Project in Nevada.
Last year, Cypress Development announced it was investigating hloride-based leaching and the potential economic and environmental benefits over sulfide-based leaching.
The company says progress to date indicates a positive alternative to a sulfate-based approach and merits consideration for the its upcoming pilot plant program.
Tests were initially done on 200-to-400-gram samples of claystone, using hydrochloric acid and sodium chloride brine as the leach solution.
Data from test results from that work was used to conduct a test on a 33-kilogram sample of claystone which yielded greater than 81 per cent extraction of the lithium into solution.
The company identified this as a starting point for the pilot plant program to expand upon these results and demonstrate that they are sustainably-operational on a larger scale.
“The company is pleased with the results from our scoping study,” said Cypress CEO Bill Willoughby.
“Chloride-based leaching represents an alternative to sulfuric acid and could be impactful in the areas of economy, process and the environment. There are still important trade-offs to consider with respect to power and acid supply, as well as some remaining analyses, but this is an alternative that will most likely become the focus of the pilot plant program. This work is critical to our goal of advancing the Clayton Valley Lithium Project towards a feasibility study later this year.”
Cypress Development is based in Vancouver and focused on developing the Company’s 100-per-cent-owned Clayton Valley Lithium Project in Nevada.
Shares of Cypress Development are up 1.25 per cent on the day, trading at C$1.62 12:50 p.m. EST.
