The British Columbia government says a proposed copper and gold mine on a First Nation's territory will not be given an environmental assessment certificate, citing potential risks to water quality and fish. In a news release, the government said Monday it has rejected the open-pit copper, gold and molybdenum Morrison mine located about 65 kilometres northeast of Smithers, B.C., which was expected to produce 30,000 tonnes of ore per day over a 21-year period.
