Alaska has a long mining historyAlaska has a long mining historyHISTORICAL DATES
1880 - Joe Juneau and Richard Harris discover gold at Juneau1886 - Treadwell Mines in Juneau are the largest underground gold mines in the world1896 - Klondike Gold Rush begins in Yukon Territory1898 – Gold discovered at Nome1900 – Copper discovered at Kennicott
1911 – 1938 Kennicott copper mine in operation1902 – Gold discovered on Pedro Creek near Fairbanks

Alaska Mining Industry Defined by Three Major Periods
1. From late 1800s until 1940s - mining was the largest industry in Alaska and provided the most jobs.
2. From 1940s until 1989 - effectively no hardrock mining in Alaska.
3. From 1989 to Present – Red Dog & Greens Creek began operation in 1989 and there’s been continued growth of minerals development ever since.
