Description Kennecott Minerals Company, a subsidiary of the Rio Tinto Group, develops, manages, and operates gold and silver mining and milling businesses throughout North America. The Denton-Rawhide Mine is 51% owned by Kennecott Minerals (with Pacific Rim Mining owning the rest). Kennecott's wholly owned Ridgeway Mine is an open pit gold mine located in South Carolina. And its Eagle Project, also wholly owned, is a nickel and copper deposit undergoing evaulation to determine its potential as a mining property. In 2007 Rio Tinto announced it would embark on a major program of divestment, in part to help pay for its acquisition of Alcan. In the process, Kennecott Minerals sold a couple of its major properties.
