NEWS RELEASE

April 23rd, 2019

Cypress Development Announces Results from Drilling at Clayton

Valley Lithium Project in Nevada

Vancouver, BC - Cypress Development Corp. (TSX-V: CYP) (OTCQB: CYDVF)

(Frankfurt: C1Z1) (“Cypress” or the “Company”) is pleased to report assay results

from its recently completed infill drilling program at the Company’s Clayton Valley

Lithium Project in Nevada. The program which commenced in March is a critical step

in the Prefeasibility Study (PFS) currently underway with Ausenco Engineering

Canada Inc., Global Resource Engineering and others.

The target area for this phase of drilling was the southwest portion of the initial pit area

as described in the October 1, 2018 Preliminary Economic Assessment NI 43-101

Technical Report (PEA). The PEA included updated mineral resources with an

Indicated Resource of 831 million tonnes at 867 ppm Li (3.835 million tonnes LCE)

and an Inferred Resource of 1.12 billion tonnes at 860 ppm Li (5.126 million tonnes

LCE), based upon a cut -off grade of 300 ppm Li. Complete assay r esults are as

provided in the following table.

Hole Top (m) Bottom (m) Interval (m) Grade Li (ppm)

GCH -07 3 142 * 140 1,032

Incl 3 91 88 1,189

GCH-08 3 112 * 109 1,127

Incl 3 87 85 1,226

GCH-09 2 118 * 116 924

Incl 2 75 74 1,115

GCH-10 3 94 * 91 948

Incl 3 54 51 1,130

GCH-11 5 124 * 119 1,004

Incl 5 87 82 1,115

GCH-12 2 114 * 112 1,127

Incl 2 81 80 1,252

* End of hole. All holes except GCH-9 and GCH-10 end in >600 ppm Li.

All drill cores from the program were geologically logged and delivered to ALS USA

Inc. in Reno for sample processing and assay. Cores from five of the six holes were

processed through sample preparation in their entirety, with coarse reject m aterial

retained for use in metallurgical tests. Intervals from three of the holes were selected

and were submitted for geotechnical testing. All samples were accompanied by

QA/QC samples of blanks, standards and duplicates.

The goal of the drilling program for the PFS was to define a n area of relative higher-

grade lithium, upgrade the categories of resources and provide the tonnage for the

PFS mine plan and production schedule. The program also provided fresh material for

geotechnical and ongoing metallurgical testing.

Cypress CEO Bill Willoughby commented, “We are pleased with the results and regard

the infill drilling program as a success. The program demonstrated consistent results

from hole to hole and achieved our goal of obtaining better -than-average grade

intervals within the target area. The results have been shared with Global Resource

Engineering who are in the process of updating the resource model from the October

2018 PEA and producing an optimized mine schedule.”

Daniel Kalmbach, CPG, is the qualified person as defined by National Instrument 43-

101 and has approved of the technical information in this release.
