Cypress Development Enters into License Agreement with Chemionex

for their DLE Technology & Equipment for 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 announce that it has

entered into a shar e purchase and license agreement (the “Agreement”) with

Chemionex Inc. (“Chemionex”), an Ontario based company, and an arm’s length third

party (collectively, the “Sellers”). The Agreement formalizes the terms of acquisition of

a license to use Chemionex’s proprietary technology for Direct Lithium Extraction

(“DLE”) (“the Lionex Process”) at Cypress’ Clayton Valley Project . The acquisition

includes pilot plant equipment designed and constructed by Chemionex, for Cypress,

which uses the Lionex Process (“Pilot Plant Equipment”).

Terms of the Agreement

Under the terms of the Agreement, Cypress shall acquire a 100% ownership in a

numbered private company (“NewCo”), incorporated in Ontario and held 100% by the

Sellers. NewCo owns the Pilot Plant Equipment and a license to use the Lionex

Process for Cypress’ Clayton Valley Lithium Project. The purchase price for NewCo,

payable at closing , comprises CAN$100,000 cash pa yment to the Sellers,

CAN$250,000 cash payable into escrow (“Escrow Cash”) and one million Cypress

shares to be transferred into escrow (“Consideration Shares”) (together the “Purchase

Price”).

The Escrow Cash will be released on delivery of the Pilot Plant Equipment to Cypress’

testing site in Am argosa Valley, Nevada. Cypress will have 12 months following

installation of the Pilot Plant Equipment to determine whether to release the

Consideration Shares to the Sellers. In the event Cypress determines not to release

the Consideration Shares, NewCo will revert back to the Sellers.

The Purchase Price grants full ownership of NewCo to Cypress with no further

payment or royalty obligations for the use of the Lionex Process.

The Agreement includes other terms and closing conditions customary for a

transaction of this nature, including TSXV approval of the Consideration Shares.

Bill Willoughby, Cypress CEO, commented: “We are very pleased to have access to

the Lionex Process in our pilot plant. The equipment and technology, along with the

consulting services of Chemionex and owner Craig Brown, will be an integral part of

our testing program. The Clayton Valley Lithium Project is unique in its setting and

physical characteristics of the clay, and this is an excellent opportunity for us to apply

and adapt Chemionex’s DLE technology to our processing solution. If successful,

Lionex will become a valuable asset for Cypress and the project.”
