Rio Tinto approves $302m investment in Resolution copper project

Rio Tinto has committed to investing a further £302m to advance its Resolution copper project in Arizona. 

The investment will fund additional drilling, ore-body studies, infrastructure improvements and permitting as Rio Tinto looks to progress the project and increase its production of the in demand red metal used in everything from tech to electric vehicles.

When fully operational, Resolution has the potential to supply nearly 25% of the United States copper demand and will create several thousand direct and indirect jobs in the Pioneer Mining District of Arizona.

Rio Tinto CEO Jean-Sébastien Jacques commented:““Resolution is one of the most significant undeveloped copper deposits in the world and this additional funding demonstrates Rio Tinto’s commitment to bring the mine into production. The comprehensive permitting process is well underway with the Environmental Impact Study on track to be completed next year according to the regulators schedule.

“The rise of electric vehicles, battery storage, new transmission technology and other green energy innovations are highly copper intensive. We need to prepare now to meet this future demand. Resolution will be well positioned to provide North American manufacturers the copper that is essential to their products.”

The Resolution project is currently in its seventh year of a comprehensive environmental review and approval process, conducted by the US Forest Service under the National Environmental Policy Act. This process has involved numerous public meetings, hundreds of government to government consultations between the Forest Service and Native American tribes and the participation of individuals, environmental groups, nearby municipalities and local businesses.

Upon this investment, project partners (Rio Tinto 55% and BHP 45%) will have invested over $2 billion to develop and permit Resolution since 2004. This includes sinking a new shaft to mining depth, rehabilitating an existing shaft, extensive drilling and ore body testing, and the permitting and public engagement process.
