(TSXV: CCCM) ("C3 Metals" or the "Company") is pleased to announce that the Company has entered into a royalty purchase and assignment agreement with Rodinia Resources Pty Ltd. ("Rodinia") to purchase 1.5% of a net smelter returns royalty (the "NSR") on the Company's Main Ridge and Hungry Gully properties located in Jamaica (the "NSR Purchase Agreement").

Kevin Tomlinson, C3 Metals' CEO stated, "We are pleased to be able to renegotiate the royalty arrangements as we recommence exploration over our high-grade gold and copper projects in Jamaica. Reducing the outstanding royalty on these properties will place us in a better position to advance exploration and introduce a joint venture partner should we decide to do so."
