Cypress Development Files for Permit with BLM

for Phase 2 Drill Program at Dean Lithium Project in Nevada

Vancouver, BC - Cypress Development C orp. (TSX-V: CYP) (OTCBB: CYDVF)

(Frankfurt: C1Z1) (“Cypress” or the “Company”) is pleased to announce it has

initiated an application to the Bureau of Land Management (BLM), Nevada, for an

area of disturbance permit to allow the Company access for a second series of

diamond drill ho les on the Dean Lithium project in Clayton Valley, Nevada. The

Company anticipates approval of the application shortly and looks to mobilize a drill

crew into the Clayton Valley beginning of September. The Phase 2 program will

consist of 8 -10 diamond drill holes totaling approximately 3000 feet.

Cypress’ Dean Lithium Project is located immediately adjacent to decades of lithium

production belonging to the Albemarle Silver Peak Mine on its west boundary, Pure

Energy's recently released lithium resource estima tion on its southwest boundary

and Cypress's Glory Lithium Project, under an option agreement with Pure Energy

Minerals, on its southern boundary.

Cypress's exploration and core drilling results received to date from its Dean Project

have been very encouraging. A large amount of data has been gathered and is being

analyzed. A 2017 Phase 2 drilling program on the Dean property is being proposed

for the third and fourth quarters to provide further infill data.

Cypress recently announced (News Release June 6, 2017) an extensive 80 to 100

metre-thick blanket of consistent lithium mineralization underlying a large majority of

its 2,700 acre Dean Property. The mineralization covers an area of approximately

two kilometers by four kilometers. The lithium mineralized volume evident on the

explored portion of the Dean property averages in excess of 1,000 ppm lithium (Li).

Cypress is continuing with laboratory studies to explore the highly reactive and

soluble nature of the large volume of lithium-enriched rock seen on the Dean Project,

so as to further understand a method of extraction and ultimately production.

Donald Huston, President of Cypress Development, stated: "This newly discovered

lithium mineralization at the Dean Project is ideally located within a basin that hosts

the only significant lithium pr oduction in the United States. Cypress' Clayton Valley,

Nevada Lithium project is in close proximity to essential mining infrastructure.

Cypress Development believes this discovery has the scale to significantly impact

the future production of lithium in t he Clayton Valley. Cypress also believes this

developing zone could very well represent a long -term, reliable supply of lithium

given the known size, chemistry and geometry of the discovery. The consistent

nature of the currently known lithium mineralization at Dean is highly encouraging for

both the potential size and potential resource extraction methodologies. The drill data

to date, which outlines an area of roughly two kilometers by four kilometers, presents

a strong starting point for planning a resou rce estimation process. This second

phase of diamond drilling should allow the Company to contemplate a sizable

maiden lithium resource calculation on the Dean Project.”

Cypress maintains this large claim block known as the Dean lithium project as a 100

per-cent owned asset.

company that continues to acquire and develop potentially viable mineral projects in

the State of Nevada, U.S.A.

Cypress is very active in Clayton Valley, Nevada with its team committed to

systematically exploring its Dean and Glory properties for both a lithiu m-brine

resource and expanding exploration relating to a lithium resource that exists within

the large area of non-hectorite “claystone” discovered at surface that has seen

recent high lithium assays recovered from these same “outcropping claystone”.

Cypress Development Corp. has approx. 35.0 million shares issued and outstanding.
