Keith Marshall, former general manager of the Greens Creek Mine, has relocated to London to serve as the mining executive for the Diamonds & Gold Product Group of Rio Tinto. Marshall, who joined Rio Tinto in 1991, spent four years as a temporary employee of Kennecott Mineral.
Marshall was replaced at Greens Creek on Oct. 1 by Rich Heig, former general manager of Rio Tinto Technical Services North America in Salt Lake City. Heig joined Kennecott in 1987 and has subsequently held a number of technical and management operations roles including vice president of operations at Utah Copper.
"Rich's familiarity with Kennecott Minerals and the Greens Creek operation will be a great asset toward the continuing successes of Kennecott Minerals and the Greens Creek Mine," said Kennecott Minerals President and CEO William Orchow.
