TUCSON, Ariz. (AP) — The company proposing to build an Arizona copper mine has submitted a request for a federal judge to vacate or amend a ruling that stopped work.
The Arizona Daily Star reported Wednesday that Rosemont Copper Co. has asked U.S. District Court Judge James Soto to change his July 31 ruling because it says opponents lack standing to sue.
The company says Soto ruled that Rosemont Copper lacked valid mining claims on public land where it wants to dump waste rock and tailings.
Officials say the request is the first step toward appealing the ruling concerning the $1.9 billion open-pit mine project.
Rosemont Copper is the Arizona subsidiary of Toronto-based Hudbay Minerals Inc., which holds the mining claims and owns the property 36 miles (58 kilometers) southeast of Tucson.
