Graph of critical minerals that have been found, or are suspected to be present, in Alaska. Net import reliance (imports minus exports) is expressed as a percentage of domestic consumption. Although gold and molybdenum are net exported minerals, they are important to the economies of the United States and Alaska. Figure prepared by Graham Lederer. Placer deposits form when minerals are separated by density as lighter minerals remain suspended and more dense minerals are deposited along the riverbed. Bedrock and beach sand deposits constitute the locations of the largest mines.
