“This transaction not only monetizes Castle’s 60% interest in Elmtree, but positions our shareholders to receive future development and exploration upside at Elmtree,” stated Mr. Mike Sylvestre, President & CEO of Castle Resources. “Given Castle’s 100% focus on the exploration and development of the Granduc Copper Project in Northwest B.C., we are pleased with CNRP’s strategy to further explore and optimize the economics of the Elmtree deposit.”

The Letter of Intent (the “Letter of Intent”) defines the essential terms under which the parties would enter into a definitive binding agreement (the “Definitive Agreement”) whereby CNRP Mining Inc. (“CNRP”) would acquire from Castle: (i) Castle’s 60% interest in the Elmtree Gold Project, and (ii) all rights, title and interest to that certain option agreement (the “Option Agreement”) executed between Castle and Stratabound Minerals Corp. (“Stratabound”) whereby Castle can acquire from Stratabound a further 10% interest in the Elmtree Gold Project all in accordance with and on the terms set out in the Option Agreement.

Simultaneous with the transactions contemplated by the Definitive Agreement and as set out in the Letter of Intent, CNRP has agreed to be acquired by Gorilla Resources Corp., a public company listed on the Canadian National Stock Exchange (“Gorilla”), in a reverse take over (“RTO”), through the issuance by Gorilla of 38,800,000 common shares of Gorilla. At closing of the RTO, the CNRP shares that Castle will receive, will result in Castle holding 18,000,000 shares of Gorilla valued at $4.5 million representing 33.43% of the share capital of Gorilla following completion of the RTO closing. Please see press release of Gorilla of today’s date for more information on the RTO transaction. The shares issuable to Castle will be subject to a lock-up in favour of Danny Wettreich, President and CEO of CNRP, for a period of 24 months following closing unless Castle distributes such shares to its shareholders in which case the lock-up will no longer apply. Under the terms of the Letter of Intent, Castle is also provided with the ability to nominate one director to the board of the newly formed company public junior resource company.

Castle’s obligations under the Letter of Intent are subject to, among other things, completion by Castle of satisfactory due diligence on CNRP and the properties which it holds or which it will hold upon completion of the RTO, all required third party consents and receipt of all required regulatory approvals.
