/CNW/ –

Cypress Development Corp.

(TSXV: CYP) (OTCQX: CYDVF) (Frankfurt: C1Z1) (Cypress or Company) is pleased to report it has achieved a significant milestone with the production of 99.94% lithium carbonate (Li

2

CO

3

) made from lithium-bearing claystone from the Company’s 100%-owned Clayton Valley Lithium Project in

Nevada, USA

(Project). The Li

2

CO

3

was derived from the intermediate concentrated lithium solution produced at Cypress’ Lithium Extraction Facility in

Amargosa Valley, Nevada

(Pilot Plant). Following direct lithium extraction (DLE) at the Plant, Saltworks Technologies Inc. (Saltworks) completed the processing system design and pilot work to make the Li

2

CO

3.

“These are excellent results for the initial iteration of testing and will be incorporated into our on-going Feasibility Study on the Project” stated

Bill Willoughby

, Cypress President, and CEO. “We are pleased to receive comprehensive assays validating the extraction process we have designed for our Project. Exceeding the standard for battery grade lithium carbonate checks-off an important goal for the Company and its further development of the Project.”

Cypress executed pilot operations through to production of ‘three nines’ Li

2

CO

3

that exceeds the standard battery grade specifications below. All processing was completed with material from the Company’s Project in an end-to-end automated pilot plant that represents full scale production. Independent analyses of product samples were completed by SGS Canada Inc., with the results showing greater than 99.9 weight-percent (wt%) purity in a scalable representative process.

“Our team is pleased with the outcome at Saltworks, and their support of our Project,” stated

Bill Willoughby

. “Cypress has engaged Saltworks to integrate their designs into our pilot plant program and look forward to their continued work on the Project.”

The final product surpasses industry requirements for standard battery grade Li

and has achieved industry requirements for enhanced battery grade Li
