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 Arizonaâ€™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 combinedâ€”mining has always been a part of Arizona. Rosemont Copperâ€™s vision is to utilize the latest mining technologies to create a bridge from Arizonaâ€™s mining past to a high-tech, renewable future.

New transmission and distribution systems for renewable energy will require millions of pounds of copper.
A single wind energy turbine contains more than 1 ton of copper.
New technologies and their copper wiring can play a key role in Arizonaâ€™s future economy.
Copper is necessary for distributing solar heated water and copper pipes remain the most energy efficient option.
New low-cost photovoltaics rely on copper.
hybrid cars Hybrid cars use twice the copper of their traditional counterparts.

Latest oxide-ore processing technology to reduce water use Electrowinning Raffinate Pond
1 Ore Pad
Lined Solution Pond
Oxide-ore placed on lined leach pad.
The ore is irrigated with weak sulfuric solution.
The solutions is pumped to a solvent extraction and electrowinning plant to produce pure copper cathodes. The water is then recycled back to the oxide ore pad.
Environmentally responsible, efficient operations The diagrams below illustrate the detailed plan of operations for the life of the mine, including reclamation that begins on Day 1.

Screening berms are put in place, and topsoil is removed and stored for later use.

Sulfide-ore is first crushed then ground into a slurry.
Flotation process produces copper concentrates.
Copper concentrates are de-watered, the water is recycled back to crushing, and the copper goes to market for further processing.
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.
