Powering Arizona’s Future: A Bold Vision for Sustainable Mining

Arizona is no stranger to mining, producing 70% of the nation’s copper and playing a critical role in the global supply chain for minerals. But the world is demanding more: more copper, more rare earth minerals, more security in the supply chain and more sustainable practices. 

The University of Arizona’s School of Mining and Mineral Resources is responding with an ambitious proposal to the National Science Foundation (NSF) to transform the mining sector while delivering significant economic and social benefits to the state.

The Sustainable Mining Innovation Leadership Engine (SMILE) seeks to position Arizona as the epicenter of next-generation mining technology and practices. Rich in critical minerals like copper, manganese, and zinc, the region offers an ideal test bed for this groundbreaking initiative. By focusing on electrification, artificial intelligence and automation, the initiative aims to decarbonize mining operations, reduce energy consumption, increase efficiency and safety, and create a thriving workforce.

The initiative also seeks to strengthen U.S. competitiveness in the critical minerals market. By reducing reliance on foreign sources for essential materials, Arizona’s mining industry could bolster the national security of the energy pipeline.

Economic Transformation for Southern Arizona

If funded, the SMILE Engine could leverage up to $2.85 billion in multi-sector economic investment and support creating thousands of high-paying jobs. “This project is about more than mining—it’s about economic empowerment and sustainability in a region that brings unique resources to bear around mining,” said Kray Luxbacher, head of the University of Arizona Department of Mining and Geological Engineering. 

At the heart of the SMILE Engine is its commitment to workforce development. Through partnerships with Pima Community College, Komatsu, South32 and the Arizona Commerce Authority, the initiative will train the next generation of mining professionals. Programs will emphasize STEM education, hands-on experience and collaboration across sectors, ensuring graduates are prepared to meet the demands of a rapidly evolving industry.

“The mining sector is transforming, and we need a workforce that can keep up,” said Misael Cabrera, Director of the University of Arizona School of Mining & Mineral Resources. “Our goal is to not only prepare students for careers in mining but to empower them to lead the way in innovation and sustainability.”

The initiative has garnered widespread support from industry, academia, and government. The University of Arizona is actively seeking public and private investment to join in the work to bring SMILE to life. 

“Arizona has always been at the forefront of mining,” said Luxbacher. “Now, we have the chance to redefine what mining looks like in the 21st century.”
