The Ruby–Poorman mining district in the U.S. state of Alaska produced nearly a half million ounces of gold, all from placer mines. Some of the largest gold nuggets found in Alaska are from the district, which lies along the Yukon River.

The mine is located in Alaska's Northwest Arctic Borough, in the DeLong Mountains of the western Brooks Range, 90 miles north of Kotzebue and 55 miles from the Chukchi Sea. At the end of 2007, the site's proven and probable reserves plus indicated resources amounted to 77.5 million tons, containing 17.5 percent zinc and 4.8 percent lead, as ...
