Cypress Reports 92 meters of 1136 ppm Li from Clayton Valley Lithium

Project in Nevada

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

(Frankfurt: C1Z1) (“Cypress” or “the Company”) is pleased to report newly received

assays of drill cores which the Company recently acquired . The cores are from four

holes drilled as shown in the figure below and located in an area south of the proposed

mine area in the Company’s May 2020 Prefeasibility Study (NI 43-101 Clayton Valley

Prefeasibility Study Technical Report ). The assay results are summarized in the

accompanying table.

The assay r esults are significant with three of the holes having continuous intervals

averaging greater than 1,100 ppm Li. The longest is a 92-meter interval of 1,136 ppm

Li in CM001, located 750 meters southeast of the PFS pit limits. The lithium grades

reported here are similar to those of the Probable Reserves in the PFS, estimated at

222.8 million tonnes of 1,141 ppm Li (1.353 Mt LCE) . The results demonstrate the

potential for additional resources within an area of 1,106 acres that were not included

in the PFS resource model.
