Cypress Development Corp. (TSX-V: CYP) (OTCQB: CYDVF) (Frankfurt: C1Z1) 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.

HQ-size drill cores from the four holes were received intact, properly boxed and in good condition. All cores were logged, split and sampled by Cypress at ALS in Reno Nevada, and analyzed by ALS in Vancouver, B.C. Company QA/QC procedures were followed.

The assay results 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.
