[{"type":"text","content":" VANCOUVER, British Columbia, Feb. 27, 2020 (GLOBE NEWSWIRE) -- 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 Step Li (ppm) Mg (ppm) Ca (ppm) Fe (ppm) Al (ppm) Feed 380 3340 339 2270 1395 Purified 360 54 15 40 10 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...
