Rock Creek Mine Biological Opinion

On May 13, 2003 the U.S. Fish and Wildlife Service issued a non-jeopardy biological opinion on Sterling Corporation’s proposed Rock Creek Mine in the Cabinet Mountains of Montana. The non-jeopardy opinion concludes that the proposed silver and copper mine would not jeopardize the continued existence of grizzly bears or bull trout in this area. In addition, lynx are not likely to be adversely affected by the proposed mine.
