Resolution Copper history
Resolution Copper company history timeline
By January 2003, this exploration effort had established continuity of mineralization over an area measuring at least 3,300 feet in diameter.
In March 2004, Rio Tinto earned its 55% interest in the Superior property and officially took over as its operator in May 2004.
2004 – Rio and BHP form the Resolution Copper Co to explore the deposit.
2005 – The San Carlos Apache tribe and others voice opposition to the project on religious and cultural grounds.
10 shaft, underground work was initiated to rehabilitate and extend the Never Sweat Tunnel in September 2006.
9 shaft at the East Plant site, began in February 2007 with the construction of the collar set up.
The actual sinking of this 28-foot diameter shaft commenced in January 2009.
That is less than half the amount it was spending in 2012, when the investing companies grew weary of the slow progress in Congress.

It was completed to a depth of 6,943 feet on November 18, 2014, making it the deepest single-lift shaft in the United States.
As of December 31, 2014, it was reported to contain an inferred resource of 1.947 billion short tons, averaging 1.51% copper and 0.035% molybdenum, based on classification criteria published by the Australian Joint Ore Reserves Committee (JORC).
2014 – US President Barack Obama signs a Pentagon funding bill approved by Congress that includes a clause – added at the last minute by then-Senator John McCain, of Arizona – to give Rio the campground and surrounding acreage in exchange for land it owns nearby.
Meanwhile, US Representative Raul Grijalva, an Arizona Democrat, introduces a bill to overturn the part of the 2014 bill that allowed the land swap – considered by Native American leaders the best hope for blocking the mine.
2017 – A Rio Tinto executive tells Congress the company would smelt copper mined from Resolution in Utah, addressing fears that the Arizona copper could be shipped to China for processing.
2019 – The San Carlos Apache Tribal Council votes unanimously to oppose Resolution.
March 2021 – President Biden blocks the land swap by rescinding Trump’s publication of the environmental study.
