Cypress Advancement to begin pilot plant program for Clayton Valley Lithium Task, Nevada

Cypress Development Corp. ( TSXV: CYP) ( OTCQB: CYDVF) ( Frankfurt: C1Z1) (” Cypress” or “the Company”) is delighted to report that the assembly of the pilot plant for the Company’s 100%- owned Clayton Valley Lithium Project in Nevada is total. The pilot plant lies at a metallurgical center roughly 100 miles south of the task. Getting of products for the pilot plant started in March and work advanced through the summer season. With assembly and functional screening of part devices completed, test extraction of lithium from the job’s sample product will start next week. The pilot plant will use chloride-based seeping integrated with the Chemionex– Lionex procedure for direct lithium extraction (DLE), as explained in previous statements.

” The conclusion of the pilot plant represents a substantial turning point and marks the conclusion of months of work by Cypress, our experts, and specialists” mentioned Bill Willoughby, President and CEO of Cypress. “This work, under the instructions of Continental Metallurgical Services and supported by the management and workers of del Sol Refining, Inc., has actually led to a pilot plant that embodies the research study that entered into our procedure flowsheet. The screening ahead will be among the bigger piloting efforts to draw out lithium from clay worldwide, and the just one based upon a chloride technique to seeping. While the supreme objective is to show the production of lithium hydroxide from our claystone resource on a bigger scale, the arise from the different locations within the plant, from seeping and tailings managing, to service treatment and recycling, chemical use and water balance, will offer the information needed to bring the task forward to the expediency level.”

The Company’s pilot plant is set up to utilize chloride-based seeping to free the lithium from the task’s claystone. This was based upon arise from an internal scoping research study finished in January 2021, which identified fringe benefits in the locations of economics, procedure, and the environment when utilizing a chloride-based instead of a sulphate-based leaching procedure. The sulphate-based procedure stays a practical option as detailed in the job’s Pre-Feasibility Study(PFS, reliable Date August 5, 2020 and modified March 15, 2021).

Pilot Plant Program Objectives

The pilot plant is planned to validate the extraction of lithium from the Company’s Clayton Valley Lithium Project, in following the suggestions detailed in the Company’s PFS.

There are 4 primary areas in the pilot plant: seeping, tailings dealing with, pregnant leach service (PLS) treatment and the Chemionex– Lionex DLE procedure location. 2 extra processing actions will be performed off-site at NORAM Engineering and Construction, Ltd’s B.C. Research Laboratory in Richmond, Canada; these actions will take the focused lithium option and a part of the diminished option following DLE for the production of lithium hydroxide and the generation of hydrochloric acid and salt hydroxide.

Each area in the pilot plant has particular goals. The seeping area will work to enhance leach conditions and validate lithium extraction into PLS. Checking of different feed size and grade of the claystone, reagent mixes, and water balance will assist in optimization at scale.

The tailings managing area will use a counter existing decantation plan of thickener inhabitants and flocculant blending, with the goal of figuring out products dealing with, wetness material and water usage. Evaluating in this phase will supply essential info for water requirements and style of tailings centers.

The PLS treatment area will get rid of pollutants prior to intro into the DLE procedure through two-stage neutralization and filtering, a tertiary phase will follow the DLE procedure prior to recycling of service back to seeping.

The DLE area includes Chemionex’s– Lionex DLE innovation and will evaluate compatibility of the PLS to be additional focused with this procedure. Cypress was given an alternative, upon conclusion of the pilot plant program, to accredit this procedure for business usage at its job.

The last 2 actions will be performed by NORAM Engineering, these will deal with the focused lithium option from the DLE part of the pilot plant to produce lithium hydroxide and test the removed leach service for compatibility for recycling to the seeping area of the plant.

About Cypress Development Corp

Cypress Development Corp. is a Canadian sophisticated phase lithium expedition business, concentrated on establishing its 100%- owned Clayton Valley Lithium Project in Nevada, USA. Work finished by Cypress resulted in the discovery of a first-rate resource of lithium-bearing claystone nearby to the Albemarle Silver Peak mine, North America’s only lithium salt water operation. The outcomes of a favorable Pre-Feasibility Study for the Clayton Valley Lithium Project were revealed by Cypress Development in August2020 Cypress Development trades on the TSX Venture Exchange under the sign CYP, and on the OTCQB under the sign CYDVF.
