Hecla Mining Company
A North American miner that digs silver, gold, lead, zinc, and copper from mines in Alaska, Idaho, Yukon, and Quebec, selling the metal-rich concentrates and doré it produces to smelters and refiners. Founded in 1891 in Idaho's Silver Valley, it is one of the largest primary silver producers in the United States. The company took its name from Mt. Hekla, an Icelandic volcano whose picture once hung in its payroll office.
