Cypress Files Notice with BLM for Four Drill Holes Targeting Lithium Brines at Clayton Valley Project, Nevada

April 21, 2016

Vancouver, BC - Cypress Development Corp. (TSX-V: CYP) (OTCBB: CYDVF) (Frankfurt: C1Z1) ("Cypress" or the "Company") is pleased to announce the Company has filed a Notice of Intent permit with the BLM, Nevada covering a planned four hole drill program targeting lithium brines at the Company's 1320 acre Clayton Valley Lithium Project located in Esmeralda County, State of Nevada, USA.

Cypress' Clayton Valley Project is located on the south flank of "Angel Island" and immediately southeast of the Albemarle Silver Peak lithium mine. Cypress' Clayton Valley claims share their western boundary with placer claims controlled by Pure Energy Minerals. Pure Energy has identified a lithium resource at its northern resource area (see Pure Energy's news release July 28, 2015), that is located to the immediate west of Cypress' established boundary.

Cypress' planned Clayton Valley subsurface exploration program is expected to be initiated in either late Q2 or early in Q3, 2016.

The permit application contains four proposed reverse circulation ("R-C") drill holes targeting lithium brines within the main ash aquifer projected to underlie the west and west-central portion of Cypress' Clayton Valley project. The main ash aquifer is the primary target of all four R-C holes. Cypress expects to intersect this zone at approximately 500 feet below surface. Additional deeper targets will also be tested including the potential presence of a coarse gravel aquifer near the base of the basin fill evaporite sequence.

  1. R-C hole CYP-1 will target the main ash aquifer immediately east of Pure Energy Minerals hole CV-1 and Rodina hole SPD-9.
  2. R-C hole CYP-2 will target the main ash aquifer within a strong NNE trending structural zone which appears to be the major bounding fault along the southeast flank of Angel Island.
  3. R-C hole CYP-3 will target the main ash aquifer east of Pure Energy Minerals hole CV-2.
  4. R-C hole CYP-4 will target the main ash aquifer in the southwestern portion of the property.

The permit also contains proposed locations for 25 shallow auger holes targeted to provide initial subsurface data and assays under areas of strongly lithium mineralized salty claystone outcrops. The auger holes are planned to be approximately 30 feet in depth and will be sampled on composite 5 foot intervals.

A Phase 2 surface sampling program is currently underway at Cypress' Clayton Valley project which will better define the extent of the high-grade surface lithium mineralization identified in the Phase 1 January 2016 sampling program. The first sample group has been submitted to ALS Chemex in Reno, Nevada and Cypress is awaiting the assay results.

The surface sampling and reconnaissance geologic results received by Cypress to date are viewed as being highly encouraging for the presence of lithium rich brines within the subsurface aquifers below the mineralized claystone.

Clayton Valley is located within the Basin and Range Province in southern Nevada and is an internally drained, fault bounded and closed basin. Basin-filling strata compose the aquifer system which hosts and produces the lithium-rich brines.
