To aid the U.S. Army Corps of Engineers in their resource development navigation study of 10 existing or proposed port sites in Alaska, the U.S. Bureau of Mines examined the potential for mineral development around three Alaska port sites: Iliamna Bay, Kotzebue, and Nome. The mineral deposits near Iliamna Bay include gold, copper, and iron. Development of minerals in this area will require the discovery of new deposits or the definition of additional ore reserves at known deposits. The mineral deposits near Kotzebue are primarily gold, copper, coal, lead, and uranium. Based on the character of these deposits, it appears that development of a small-scale mine supplying coal for regional use is the most likely scenario in the near term. The mineral deposits near Nome are primarily gold and copper. Development of small underground gold mines is possible; however, it appears that expanded offshore gold dredging will have the greatest impact on the flow of freight and goods through the Nome port in the near term.
