Southern Copper — Feb 11, 2025 release

We anticipate that El Pilar will operate as a conventional open-pit mine with an annual production capacity of 36,000 tonnes of copper cathodes. This operation will use highly cost efficient and environmentally friendly SX-EW technology. The budget for El Pilar is $310 million. ​ The results from experimental pads in the leaching process have confirmed adequate levels of copper recovery and we are evaluating different options for optimization. The Company is engaging in project development and on-site environmental activities. Mine life is estimated at 13 years. ​ 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. ​ The Company has completed the environmental baseline study for the mine. Currently, more detailed engineering is being conducted for concentrator, SX-EW plant as well as for water desalination, logistics infrastructure and power delivery.  ​ ​ ​ 4Q24 www.southerncoppercorp.com Page 3 of 12 ​ ​ ​ ​ ​ ​ ​ ​ ​ FOURTH QUARTER AND YEAR 2024 RESULTS SOUTHERN COPPER ​ ​ ​ ​ SCC has several projects in its Mexican pipeline that may boost organic growth if they are found to be of value for both stakeholders a
