Kennecott Employees: 250
(70.3% Kennecott owned and operated;
Partner: Hecla Mining Company 29.7%)
|Located on Admiralty Island, near
Juneau, Alaska, the Greens Creek Mine, with 250 employees, is a joint venture
between Kennecott Greens Creek Mining Company (70.3 percent) and Hecla Mining
Company (29.7 percent).
The Greens Creek silver, gold, zinc and lead underground mine and concentrator facility began operation in 1989, but was placed on standby in 1993, followed by a $114 million modernization and redevelopment investment over a three-year period. Operations resumed in 1996.
With a projected 17-year mine life, Greens Creek is one of the nation's largest silver producers. The operation has a designed mining and processing rate of 1,320 tons per day. In 1997, the operation produced approximately 9 million ounces of silver, 46,000 ounces of gold, 34,000 tons of zinc and 15,000 tons of lead in concentrate and doré bars.
Current ore reserves contain recoverable metals (Kennecott's 70.3 percent share) estimated at 82 million ounces of silver, 628,000 ounces of gold, 675,000 tons of zinc and 225,000 tons of lead.
In 1996, Congress passed and President Clinton signed into law, a land exchange with the U.S. Forest Service that provides Greens Creek with access and mineral rights to an additional 7,500 acres surrounding the property. This land, which was previously closed to exploration, has excellent mineral potential and may extend Greens Creek's reserves and mine life substantially.
