DENVER, Dec. 04, 2018 - TriMetals Mining Inc. (TSX: TMI) (OTCQX:TMIAF), (“TMI” or the “Company”), announces that the Company has executed a letter of intent (the “LOI”) with Wealth Minerals Ltd. (TSXV:WML) (“Wealth Minerals”), a Vancouver BC, Canada based mineral exploration company, with respect to the divestiture of the Company’s 100% interest in the Escalones Copper Project in Chile (the “Escalones Copper Project”) to a newly formed, copper-focused, subsidiary of Wealth Minerals (“Wealth Copper”) that Wealth Minerals is to spin-out to its shareholders (the “Spin-Out”).

Eric Edwards, President & CEO of TMI commented, “We are very pleased to be partnering with Wealth Minerals to advance exploration on the large and prospective Escalones Copper Project. Wealth has a demonstrated history and experience in discovering and advancing exploration and development projects worldwide. Their technical and financing teams have repeatedly demonstrated their unique ability to identify projects at an early stage that have the potential to become major producing projects. We look forward to the next phases of discovery and value addition at Escalones under Wealth leadership”.

In consideration for the sale of the Escalones Copper Project to Wealth Copper, Wealth Copper is to issue to TMI such number of common shares that represents 30% of its issued and outstanding common shares and will pay to TMI a total of Cdn$1.0 million in cash in installments of which Cdn$150,000 is to be paid now, and of which Cdn$350,000 is to be paid on the closing of the Wealth Copper Private Placement (as defined below), with the remaining Cdn$500,000 to be paid on the one year anniversary of closing of the Wealth Copper Private Placement. In addition, a wholly-owned Chilean subsidiary of Wealth Copper (“Wealth Copper Chile”) is to grant TMI a 2% net smelter returns royalty payable on production from the Escalones Copper Project concessions, if the copper price is greater than US$0.75 per pound, and a 1% net smelter returns royalty if the copper price is equal to or less than US$0.75 per pound, subject to a buy-back right.

Under the terms of the LOI, Wealth Minerals will have a 45 day exclusivity period to complete its technical and legal due diligence on the Escalones Copper Project and the subsidiaries of the Company that hold title to the Escalones Copper Project assets. Following successful completion of due diligence, Wealth Minerals will determine, at its sole discretion, whether Wealth Copper will acquire the Escalones Copper Project by way of the acquisition of all of the shares of the Company’s Chilean subsidiary, TriMetals Mining Chile SCM, or by way of an assignment and transfer of all rights, title, benefit and interest in the assets comprising the Escalones Copper Project and the assumption of all liabilities related to such assets.

Prior to or concurrently with completion of the Spin-Out, Wealth Copper is to raise at least Cdn$5.0 million in funding (the “Wealth Copper Private Placement”), and TMI is to hold 30% of the shares of Wealth Copper post-funding and will also be entitled to nominate one representative to Wealth Copper’s board for so long as TMI holds at least 20% of the issued and outstanding shares of Wealth Copper. TMI will also have a right to participate in future equity financings of Wealth Copper for up to two years post-closing to allow TMI to maintain its pro rata interest in Wealth Copper.

TMI’s sale of the Escalones Copper Project is subject to the parties negotiating and executing a definitive agreement no later than February 28, 2019, and is also subject to Board and regulatory approval.
