• Cypress Development (CYP) achieves a significant milestone with the production of 99.94 per cent lithium carbonate (Li₂CO₃) made from lithium-bearing claystone from Clayton Valley Lithium Project in Nevada, USA
• Saltworks Technologies completes the processing system design and pilot work to make the Li₂CO₃
• Cypress Development (CYP) is a Canadian based advanced stage lithium company focused on developing its 100%-owned Clayton Valley Lithium Project in Nevada, USA
• Cypress Development (CYP) is up today, trading at C$1.40 as of Sep 19, 4:28 pm ET

Cypress Development (CYP) has produced 99.94 per cent lithium carbonate (Li₂CO₃) made from lithium-bearing claystone from Clayton Valley Lithium Project in Nevada.

The Li₂CO₃ 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 completes the processing system design and pilot work to make the Li₂CO_3.

Pilot operations show production of ‘three nines’ Li₂CO₃ that exceed 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, with the results showing greater than 99.9 weight-percent (wt%) purity in a scalable representative process.

The final product surpasses industry requirements for standard battery grade Li₂CO₃ and has achieved industry requirements for enhanced battery grade Li₂CO₃ for xEV use. It is common practice for lithium battery manufacturers to have specific requirements for Li2CO3 used in their products depending on the application.

Daniel Kalmbach, CPG, is the qualified person as defined by National Instrument 43-101 and has approved the technical information in this release.

Cypress Development (CYP) is a Canadian-based advanced-stage lithium company focused on developing its 100%-owned Clayton Valley Lithium Project in Nevada, USA.

Cypress Development (CYP) is up today, trading at C$1.40 as of Sep 19, 4:28 pm ET.
