Southern Copper — Jul 28, 2025 release

​ Mexican Projects ​ We are currently expecting to obtain permits and licenses that had been put on hold by the previous government in Mexico. We are conducting talks with the current administration to continue rolling out SCC ’ s Mexican investments for $10.2 billion. ​ Minera Mexico is planning to invest more than $600 million in 2025 at both its open pit and underground mines. Half of this investment will be used to guarantee the viability of long-term operations by actively modernizing and updating assets. The remaining funds will target improvements in water usage and tailings management to ensure that our operations are safe and efficient. In addition, we will invest in efforts to bolster optimization and growth. ​ El Arco - Baja California: This is a world-class copper deposit located in the central part of the Baja California peninsula with sulfide ore reserves of over 1,230 million tonnes and an average ore grade of 0.40%, and 141 million tonnes of leach material with an average ore grade of 0.27%. The project includes an open-pit mine with a combined 120 ktpd concentrator and 28 ktpy SX-EW operations. ​ Detailed engineering is still underway for the concentrator, SX-EW plant, water desalination, logistics infrastructure and power delivery. ​ El Pilar - Sonora: This low-capital intensity copper greenfield project is strategically located in Sonora, Mexico, approximately 45 kilometers from our Buenavista mine. Its copper oxide mineralization contains estimated proven and probable reserves of 317 m
