Stantec, a global leader in sustainable design and engineering, has been selected by Resolution Copper Mining LLC (Resolution Copper) to deliver a US$16 million feasibility study providing engineering and technical services for the Resolution Copper mine in Superior, Arizona. The proposed underground mine has the potential to be one of the largest producers of copper in North America¡ªsupplying up to 25% of US copper demand each year. Copper from the mine will be used in products that are vital to the energy transition, such as electric vehicles, batteries, solar panels, wind turbines, and more.

Resolution Copper is a limited liability company that is owned by Rio Tinto (55%) and BHP (45%). Â鶹´«Ã½ has been a lead underground mining and infrastructure consultant on the project since early 2019. Â鶹´«Ã½ will assist Resolution Copper by providing engineering and execution planning services for the mine.

¡°Resolution Copper is mining a critical resource needed for the energy transition,¡± says Mario Finis, executive vice president for Â鶹´«Ã½¡¯s Energy & Resources business. ¡°We are proud to support our client in this important endeavor with a strong commitment to sustainable mining throughout the entire life cycle of the project.¡±

Stantec¡¯s engineering services on this project include power distribution, material handling, shafts and hoisting systems, dewatering/pumping, communications, and more. Additionally, Â鶹´«Ã½ is evaluating the use of battery electric vehicles to help the mine meet its goal of zero carbon emissions.

Stantec¡¯s Mining, Minerals, and Metals team is helping clients achieve net zero mining¡ªthrough its holistic service offering, Sustainable Mining by Design?, which aids companies to meet their environmental, social, and governance obligations by finding ways to reduce energy demand and utilize clean sources of energy. The mining industry must be the starting point for any discussion about our energy future. To learn more about Â鶹´«Ã½¡¯s Mining, Minerals, and Metals team, click here.
