Cypress Development to Collaborate on Lithium Research Projects

Vancouver, BC - Cypress Development Corp. (TSX-V: CYP) (OTCQB: CYDVF)

(Frankfurt: C1Z1) (“Cypress” or “the Company”) , developer of a world class lithium

claystone deposit in Nevada, announced today, the Company, as an industrial partner

with several high tech research entities, has been encouraged along with its partners

in full project proposal submissions to the Department of Energy (DOE), Office of

Energy Efficiency and Renewable Energy (EERE). This has culminated in the recent

formal submittal of two lithium project proposals for research to be conducted over the

next three years.

The first project is in collaboration with the University of Utah, Colorado School of

Mines, and Cornell University, and is titled "Highly Selective Resource Independent

Lithium Extraction Processes ." This technology will demonstrate the use of Next

Generation Lithium Ion Sieve Technology (NGLIST) as an innovative and low-impact

processing method for recovering lithium including lithium contained in clay minerals.

The second project will be done in partnership with the University of Utah, Pacific

Northwest National Laboratory (PNNL), and Cornell University, and is titled "Novel and

Adaptive Amino Acid Looping Strategy for Directing Lithium Carbonate Synthesis by

Using CO2 (NASCENT)."

"We are pleased to have the EERE encourage these two research efforts in

partnership with the University of Utah, Colorado School of Mines, PNNL, and Cornell

University" said Todd S Fayram, Chief Metallurgist for Cypress . "Successful

completion of either project will allow for more efficient utilization and lower cost

recovery of lithium including from the claystone resource s in Cypress’ depos it in

Clayton Valley, Nevada”.

On May 19, 2020, Cypress announced positive results of a Prefeasibility Study for the

Clayton Valley Lithium Project in Nevada (May 2020 Prefeasibility Study) prepared by

Continental Metallurgical Services (CMS) of Butte, Montana and Global Resource

Engineering (GRE) of Denver, Colorado. On August 11, 2020, Cypress announced a

55% increase in the Measured and Indicated Mineral Resources at the Clayton Valley

Project to 929.6 million tonnes averaging 1,062 ppm Li (5.2 Mt LCE) based on a cut -

off grade of 900 ppm Li, utilizing the same economic and mining parameters found in

the Company's May 2020 Prefeasibility Study.

Exploration and development by Cypress discovered a world-class resource of lithium-

bearing claystone adjacent to the Albemarle Silver Peak mine, North America's only

lithium brine operation. The size of the resource makes the Clayton Valley Project a

premier source that has the potential to impact the supply of lithium for the fast-growing

global energy storage battery market.
