(TSXV: CYP) (OTCQX: CYDVF) (Frankfurt: C1Z1) ("Cypress" or "the Company") is pleased to announce that, together with its wholly owned subsidiary Cypress Holdings (Nevada) LTD, it has entered into a Definitive Purchase and Sale Agreement with Enertopia Corporation ("Enertopia") (OTCQB: ENRT) pursuant to which Cypress will acquire Enertopia's Clayton Valley Lithium Claystone Project ("Enertopia's Project") located immediately adjacent to Cypress' Clayton Valley Lithium Project in Nevada.

"We are excited to consolidate Enertopia's Project with our Project, as it will add upside, and can easily be integrated into our mine plan," stated Bill Willoughby, President and CEO of Cypress Development. "This is a strategic acquisition, and it will potentially aid in optimization, and production schedule development for our upcoming Feasibility Study."

Under the transaction, Cypress will pay US$1.1 million in cash and issue 3,000,000 common shares in the capital of Cypress ("Share Considerations") to Enertopia to purchase 100% ownership interest in Enertopia's Project. Closing is expected to be completed in April 2022 and is subject to customary approvals and closing conditions for a transaction of this nature, including approval of the Share Consideration by the TSX Venture Exchange.

Enertopia's Project is 100% owned by Enertopia and comprises 17 unpatented mining claims totaling 160 contiguous acres. A March 2020 NI 43-101 compliant technical report on Enertopia's Project states the property has an Indicated resource of 82 million tonnes (mt) of 1,121 parts per million (ppm) Li and an Inferred resource of 18 mt of 1,131 ppm Li using a cutoff grade of 400 ppm Li. The resource was calculated using assay data from four core holes drilled on the property in 2018.
