Cypress Development Corporate Update

December 11, 2018

Vancouver, BC - Cypress Development Corp. (TSX-V: CYP) (OTCQB: CYDVF) (Frankfurt: C1Z1) (“Cypress” or the “Company”) is pleased to provide an update on the Company’s Clayton Valley Lithium Project in Nevada.  Cypress is making progress on the work towards the prefeasibility study (PFS) outlined in its recently completed Preliminary Economic Assessment (see news release Oct. 1st), including an infill drilling program, further metallurgical testing, and the initiation of baseline studies.

“Cypress is continuing to work on steps to de-risk the project and complete the prefeasibility study in the first quarter of 2019.  Metallurgical tests are underway and focused on optimizing conditions of the process flowsheet.” stated Bill Willoughby, CEO.  “As we enter 2019, we anticipate further progress as we complete infill drilling in the pit area outlined in the PEA and Cypress obtains additional material for larger-scale tests."

Infill Drill Program

Cypress has prepared an application to modify its existing drilling permit for its infill program. The program is planned for up to 1500 meters of drilling within the area between previous holes GCH-06 and DCH-10, which is identified as the higher-grade center of the deposit. Drilling is expected to begin in early 2019, and will provide information to upgrade resource categories, further define a production schedule for the PFS, and provide additional material for further metallurgical tests. 

Metallurgical testing for the PFS is already underway using sample material from the existing drill core. The metallurgical program is focused on optimizing leaching conditions with respect to acid concentration, residence time, and other parameters, and subsequent steps in concentrating lithium in the leach solutions leading to the production of lithium carbonate. As more material is obtained from infill drilling, tests will focus on composite samples of the individual clay units within the pit area, and on larger composites representative of the PFS production schedule.

Cypress is working on other steps related to the project and completion of the PFS, including preparation of a Plan of Operations and the initiation of environmental baseline studies.
