Hecla Mining Co was established in 1891 in northern Idaho's Silver Valley. The Company produces lead, zinc and bulk concentrates, which it sells to custom smelters, and unrefined bullion bars containing gold and silver, which are further refined before sale to precious metals traders. It operates in three segments, namely the Greens Creek, Lucky Friday, and Casa Berardi units. The Greens Creek unit is located on Admiralty Island, near Juneau, Alaska. Greens Creek is 100% owned and has been in production since 1989, with a temporary care and maintenance period from April 1993 through July 1996. The Lucky Friday unit is located in northern Idaho. Lucky Friday is 100%-owned and has been a producing mine for the Company since 1958. Production at the Lucky Friday unit began ramping up during February 2013. The Casa Berardi unit is located in the Abitibi region of north-western Quebec, Canada. Casa Berardi is 100% owned and was acquired on June 1, 2013. The Company competes with other mining companies for the services of skilled personnel and contractors and their specialized equipment, components and supplies, such as drill rigs, necessary for exploration and development.
