The planned Rosemont Copper Mine just south of Tucson isn’t the only mining controversy in Arizona. It isn’t even the biggest.
About 100 miles north of Tucson, Resolution Copper Mining wants to build a mine in Superior, a town of 2,800 people, that could yield 1 billion pounds of copper a year. That’s more than four times the projected output for Rosemont Copper’s planned mine in the Santa Rita Mountains, which would produce an estimated 243 million pounds of copper annually.
Resolution — owned by mining giants U.K.-based Rio Tinto and Australia-based BHP Billiton — says the mine would create 1,400 jobs and generate $61 billion over its 40-year lifespan, plus construction and clean-up time. It would extract enough copper to meet 25 percent of U.S. demand.
“If you can imagine five Super Bowls in Superior every year for 60 years, that’s the level of economic boost and economic activity this mine is going to generate,” said Andrew Taplin, Resolution Copper Mining’s project director since October 2012. But the project would also permanently alter an outdoor destination popular with Southern Arizonans. At the Oak Flat campground, five miles east of Superior, stone picnic tables are shaded by centuries-old oak trees.
