VANCOUVER — Cypress Development Corp. has completed a seven-day continuous run at the company’s pilot plant.

The company stated that during this period, the pilot plant operated at its designed feed rate of one ton per day of lithium claystone from the company’s Clayton Valley Lithium Project.

“From an operating perspective, we are very pleased with how the pilot plant has performed to date,” said Bill Willoughby, President and CEO in a company statement.

“Most plant components ran throughout the seven days with only minor operating issues, achieving expected targets in materials handling, reagents, and water balance. Over 400 samples of leach solutions and solids were collected and shipped to ALS Global for analysis during the testing period. We look forward to seeing the analytical results and to resume testing in the new year.”

Lease Agreement Extended

In addition, Cypress reports that the lease with del Sol Refining Inc. was amended. This extended the term through 2025 and allowed Cypress the option to expand its use of the facility, including all of the 12,000 square-foot processing building at the site.

“The last year has shown us just how important it is to have access to a permitted testing facility, and the flexibility to be able to use it as we advance our lithium project,” said Willoughby in a statement.

Cypress’ pilot plant is located at a metallurgical facility in Amargosa Valley, Nevada, at a site owned and operated by del Sol, 100 miles southeast of the Cypress’ Clayton Valley Lithium Project. Cypress stated that it leased a portion of the facility earlier this year for the construction of its lithium extraction pilot plant.
