ROSEMONT COPPER A Bridge to a Sustainable Future

Our plan will set high standards for environmental protection while creating an average of 2,900 jobs each year for Arizona and injecting $19 billion into Arizona’s economy. As federal, state, and local agencies continue an exhaustive study to ensure that proper environmental protections are in place prior to issuing permits, we invite you to review this fact booklet and give us your comments and ideas.


Our renewable future depends on copper, yet today 34 percent of our supply comes from abroad. That is one reason why the General Mining Act of to

that are essential for lowering our dependency on foreign copper. Located in an existing mining district, Rosemont Copper will set a high standard for sustainable mining practices, including using solar power, consuming less than half the water as traditional mines, and reclaiming the site as permanent open space by revegetating throughout the life of the mine.


Honoring a Proud History

By 1863, one in every four people in Arizona was a miner.

From the early Native Americans who dug for minerals, to the rugged pioneers who settled the state in search of a better life, to the hard working men and women today who produce more copper than every other state combined—mining has always been a part of Arizona. Rosemont Copper’s vision is to utilize the latest mining technologies to create a bridge from Arizona’s mining past to a high-tech, renewable future.

Tailings are dewatered and sent to dry stack, and the water is recycled back to flotation.

Our Water Conservation Commitment Rosemont is committed to importing water from the Central Arizona Project Canal to recharge pumped groundwater, ensuring neutral impact to local groundwater sources. Rosemont has agreed to guarantee the viability of private wells in the pumping vicinity near Sahuarita.
