A major mine proposal near Granisle has been rejected by the provincial government.

Environment Minister Terry Lake and Mines Minister Rich Coleman are following the advice of the province's Environmental Assessment Office.

It found the potential long-term risks of the the Morrison copper and gold mine project outweigh the potential benefits.

The proposed mine was to be located next to Morrison Lake, at the headwaters of the Skeena River, which the province recognizes as the second-largest producer of sockeye salmon in B.C.

Pacific Booker Minerals wanted to extract ore from an open pit there for at least 21 years.

The federal and provincial environmental assessment agencies invited public comment on a revised plan for the mine last year, after raising concerns about the company's original plan for dealing with waste rock storage, drainage and the protection of water quality.
