The Forest Service has approved a Canadian firm’s plan of operations for a nearly $2 billion open-pit copper mine in the Santa Rita Mountains of southern Arizona.
Toronto-based Hudbay Minerals Inc., plans to extract 112,000 tons of copper from the mine, as well as other minerals, over a span of nearly two decades.
“Rosemont is now a fully permitted, shovel-ready copper project and we look forward to developing this world-class asset,” said Alan Hair, Hudbay’s president and chief executive officer, in a prepared statement issued last week.
Opponents of the project, which include a host of conservation groups as well as area tribes, say the mine would befoul local waterways, threaten Tucson’s water supply and result in a mile-wide pit filled with polluted water.
More than half of the proposed mine, which would cover more than 5,400 acres, would be located on the Coronado National Forest. A lawsuit challenging the project is pending, and the mine’s opponents have pledged further litigation.
