Total commitments amount to $4.5 billion, with the Company initially having access to $2.25 billion.

Teitur Poulsen, Chief Financial Officer, commented «The upsizing of our Credit Facility to $4.5 billion is one of the cornerstones to advancing the Vicuña Project and keeps us on track of our goal to become a top-ten global copper producer with annual production of over 500,000 tonnes of copper once Vicuña is in full operation. We are very pleased with the commitments we have received from 12 of our existing lenders in addition to the 5 new lenders joining our Credit Facility.

«As we continue to work with our partner BHP to optimize the funding strategy for the Vicuña Project, the extension and upsizing of the Credit Facility further strengthens our financial flexibility and underscores the confidence of our lending partners in the quality of the Vicuña Project and our broader operating portfolio. Combined with our strong balance sheet and consistent operating performance, the Credit Facility positions us to fund our share of the Vicuña Project while continuing annual shareholder distributions of $220 million, creating long-term value for shareholders.»
