Cypress Expands Lithium Trend by Over 2 Kilometers at Clayton Valley Project, Nevada

February 7, 2018

Vancouver, BC - Cypress Development Corp. (TSX-V: CYP) (OTCBB: CYDVF) (Frankfurt: C1Z1) ("Cypress" or the "Company") is pleased to report results from the first four core holes on the Glory claims at the Company’s 100% held  project in Clayton Valley, Nevada. The drilling extends the trend of lithium mineralization by more than 2 kilometers south and west from the Dean claims, where, as previously reported, 14 drill holes in 2017 encountered lithium-bearing claystone over an area averaging 4 kilometers by 2 kilometers and averaging 78 meters in depth.  The four holes reported today represent the first drilling on the Glory claims. All four holes encountered lithium values averaging from 600 to 900 ppm Li from surface to depths up to 60 meters.

New Technical Report and Upcoming Drill Program at Clayton Valley Project:

In related activity, the Company has engaged Global Resource Engineers, of Denver, Colorado, to prepare a resource estimate for the Dean property. A NI 43-101 Technical Report on the geology and drilling of Dean has been completed and will be filed on SEDAR. Metallurgical testing, as reported in a previous press release on January 9th, has shown the lithium in Dean core is soluble in a solution of sulfuric acid. Testing is continuing at two independent labs, using Dean core from holes DCH-2 and DCH-5. Further results are expected to be reported this month.

Given the success of this recently completed drill program, the Company will recommence drilling shortly on Dean. Further details of this upcoming drill program are forthcoming.

Robert Marvin, B.Sc., PGeo, VP of Exploration and Director of Cypress Development Corp., is the qualified person as defined by National Instrument 43-101 and has approved of the technical information in this release.
