Frontier is pleased to announce a definitive agreement with Mitsubishi Corporation (“Mitsubishi”) (Tokyo Stock Exchange: 8058:JP) to establish a joint venture partnership (“JV”) for the PAK Lithium Project mine and planned lithium chemicals conversion facility (collectively the “Project”). This JV partnership delivers immediate and near-term financing to aggressively advance the first fully integrated lithium mining and processing operation in Ontario.
Under the terms of the agreement, signed on March 2, 2024, Mitsubishi will acquire an initial 7.5% interest in the Project for C$25 million. Upon completion of the definitive feasibility study (“DFS”), Mitsubishi will have the right to increase its interest in the JV to 25% through the purchase of additional shares at a price based on the net value of the Project as shown in the DFS. Additionally, Frontier and Mitsubishi will work closely together to pursue project financing to fund the development capital costs of the Project.
