Cypress Test Program at NORAM Engineering Completed for Clayton Valley Lithium Project in Nevada

VANCOUVER, Feb. 27, 2020 - Cypress Development Corp. (TSX-V: CYP) (OTCQB: CYDVF) (Frankfurt: C1Z1) (“Cypress” or “the Company”) is pleased to report the test program at NORAM Engineering and Constructors Ltd. (“NORAM”) is complete and initial results are positive. As reported in a November 14, 2019 press release, NORAM was contracted to examine the downstream portion of the revised extraction flowsheet for Cypress’ Clayton Valley Lithium Project in Nevada. Testing was conducted at BC Research Inc., a member of the NORAM Group of companies in Richmond, British Columbia.

The program utilized both synthetic and actual solutions generated from Cypress’ large leach tests conducted at Continental Metallurgical Services (“CMS”) in Butte, Montana. The tests simulated the purification solution and concentration steps within a portion of the NORAM-Cypress developed flowsheet. Initial results are positive and indicate the target levels of lithium concentration and rejection of impurities in solution were achieved. The pending, final report will be used to update the mass balance in the process flowsheet and complete the remining step in the Company’s ongoing Prefeasibility Study (“PFS”) on the project.

NORAM Test Results

With respect to the PFS, the Company and its consultants are actively working to complete the study. The resource model, pit design, production schedule, and site selection and infrastructure studies for the processing plant are completed.

The design is based on mining 15,000 tonnes per day of material in an effort to produce 25,000 tonnes per year of lithium carbonate equivalent (“LCE”). The mine area is designed to initially target the upper portions of the intercepts encountered in 2019 drilling (see table below). This area of drilling represents a small portion of the overall lithium resource on the property and is expected to support the design basis of production for the first 18 years of the project. The large leach tests at CMS show lithium extractions of 84-86% and confirmed values for acid consumption from the 2018 Preliminary Economic Assessment (“PEA”). Sulfuric acid remains a major consumable for the project. Quotations for an on-site sulfuric acid plant, sulfur supply and transportation were obtained. Issues related to leaching and filtration were resolved and the NORAM test program completes the remaining critical design element required for the PFS process flowsheet.

2019 Drill Intercepts

The project’s PFS is limited to the Dean and Glory mining claim-blocks totaling 4,780 acres. An additional 1,280-acre claim-block was part of the Company’s 2019 lawsuit against Centrestone Resources, LLC, and was excluded from the PFS. This contiguous claim block is located south and east of the project’s initial proposed mine area. These mining claims include the lands on which Centrestone Resources drilled two exploration holes. On December 16, 2019, the District Court entered an oral order granting summary judgment in favor of the Company on its claims against Centrestone Resources LLC. On February 6, 2020, the District Court entered its written order for summary judgment. The District Court set a hearing on April 21, 2020 in Goldfield, Nevada, to hear the Company’s damage claim.
