The total consideration will be subject to maximum aggregate cash consideration of approximately C$183 million (representing 30% of the aggregate consideration). Any cash payments on Josemaria Resources Shares traded on Nasdaq Stockholm will be paid in Swedish kronor in accordance with Euroclear Sweden principles.

On closing of the Transaction, Josemaria shareholders are expected to own approximately 5% of Lundin Mining, on a fully diluted basis.

Adam Lundin, President and CEO of Josemaria said: “I am very happy to announce this transaction today, which delivers compelling value and an immediate uplift for all Josemaria Resources shareholders. We have been exploring different financing options for the advancement and development of the Josemaria Project and we believe this is the best opportunity to develop the project without direct dilution or financing risk for Josemaria shareholders, while fairly compensating them for their interest in this world-class copper/gold deposit. Josemaria shareholders will also have the opportunity to continue to participate in the development of the project through their post-closing ownership in Lundin Mining, which has the financial strength, technical expertise, project development experience, and commitment to the highest ESG practices to advance the Josemaria project at the pace and scale this project deserves.”

Peter Rockandel, President and CEO, Lundin Mining said: “The acquisition of the Josemaria project complements Lundin Mining’s existing portfolio of high-quality mines and highlights our focus on disciplined copper-focused growth to create long-term shareholder value. Josemaria is a world-class copper project that has many characteristics which make it the ideal project for Lundin Mining to advance in the next phase of our growth. Leveraging our technical expertise, financial strength, and drawing on the Josemaria team’s in-country knowledge, we believe this opportunity will create meaningful value for all stakeholders. The addition of Josemaria will elevate Lundin Mining’s position to a major base metals producer with high-quality, low-cost copper exposure."
