Where will you be working
The Resolution Copper project is a proposed underground mine 60 miles east of Phoenix, Arizona, near the town of Superior. Resolution Copper Mining LLC (RCML) is a limited liability Company owned by Rio Tinto (55%) and BHP (45%), with Rio Tinto (RT) as manager of the project. Resolution is located in an active mining district 100 kilometers east of Phoenix, Arizona, and is one of the best-undeveloped copper deposits in the world containing over 27 million tons of copper in high-grade indicated and inferred resources.
The ore deposit lies nearly 7,000 feet below the earth’s surface. It represents one of the most significant untapped copper deposits today, with an estimated copper resource of 1.787 billion metric tonnes at an average grade of 1.5% copper. The mine has the potential to supply nearly 25% of US copper demand.
The mine will create several thousand direct and indirect jobs, with an economic value of several billion dollars over the estimated mine life. Resolution will also serve as an engine for economic growth, and use best practices to create a safe, sustainable, and environmentally friendly operation. The copper from the mine will be used to produce vital products that modern society depends upon, such as electric vehicles, smartphones, and MRI scanners.Permitting is well-underway, and the public plays a significant role in planning and approving the project.
