On September 23, 2026, Mark Scott, General Manager, Pinto Valley, and Matt Kopman, Vice President, Corporate Development, attended the Unlocking U.S. Copper Production workshop in Golden, Colorado. Thank you to U.S. Department of Energy Office of Critical Minerals and Energy Innovation, Payne Institute for Public Policy, Colorado School of Mines, and National Laboratory of the Rockies for hosting an engaging session that brought together industry peers, the Department of Energy, the Department of War, and academia. The day was full of strategic discussion and debate about the growth opportunities ahead, the challenges our industry faces, and the role technology and innovation will play in unlocking domestic US copper production. One point wasn't up for debate: copper is one of the most important host minerals, with many other critical minerals recovered as by-products. As copper miners, we have a critical role to play. Enhanced cooperation between adjacent sites presents one of the best opportunities to enable near-term US copper production growth, and Pinto Valley is perfectly situated for this within the historic Globe-Miami district.

We are pleased to announce the sale of the Cozamin mine in Mexico to Luca Mining Corp. for up to $385 million in total consideration. The transaction optimizes our portfolio and further strengthens our balance sheet, enabling us to redeploy capital into our high-return projects as we advance towards transformational copper growth in Chile and the United States.

Cozamin has been an important part of our portfolio, and we extend our sincere thanks to everyone at Cozamin for their dedication to operational excellence and safety over the last 20 years. We believe Cozamin will be well positioned under Luca’s ownership, and that the workforce, local stakeholders, and surrounding communities will benefit from Luca’s operating expertise in Mexico, safety culture, and commitment to invest in Cozamin’s future.
