Copper mining

A federal judge has rejected a request by opponents to stop Toronto-based Hudbay Minerals Inc. from preparing a planned new copper mine’s site in the Santa Rita Mountains near Tucson.

Hudbay Minerals Inc. says it may appeal a court ruling against its planned use of forest land to store waste rock from a proposed new copper mine but that it also will continue planning for a nearby related project that would include using private land.

An appeals court Thursday upheld a judge’s ruling overturning a federal agency’s approval of a Toronto-based company’s plan for a new open-pit copper mine in southeastern Arizona.

A Hudbay Minerals Inc. subsidiary plans to begin clearing and grading this month on the southern Arizona site for a planned new mine with five open pits.

A reclamation plan for a proposed new copper open-pit mine’s site on the western slope of the Santa Rita Mountains south of Tucson has received state approval over opponents’ objections that Hudbay Minerals Inc. didn’t address major issues.
