Global Geochemical Database for Critical Minerals in Archived Mine Samples The Critical Minerals in Archived Mine Samples Database (CMDB) contains chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States. In addition, the database contains samples from archetypal deposits from 27 other countries in North America, South America, Asia, Africa and Europe. Samples were obtained from archived ore collections under the U.S. Geological Survey's project titled "Quick Assessment of Rare and Critical Metals in Ore Deposits: A National Assessment" (2008 to 2013) in an effort to begin an assessment of the Nations' previously mined ore deposits for critical minerals.

Alaska. 1986. The Juneau Gold Belt portion of the Juneau Mining District has historically had the greatest mining and exploration activity within the district and is the subject of this report. Between 1880 and 1983, the mines within the Juneau Gold Belt produced 6.7 million oz gold, 3.1 million oz silver, and 45 million lbs lead, all of which had a total value of about $157,000,000. Information in this report is based on an extensive literature search which included unpublished private company reports, U.S. Geological Survey, State of Alaska, and Bureau reports, personal interviews, and Bureau field work. The field work during 1985 revealed the locations of numerous adits, shafts and other old mine workings, many of which were...

As part of a cooperative project during 1986 and 1987, personnel from the U.S. Bureau of Mines and State of Alaska Division of Geological and Geophysical Surveys studied the mineral development potential of the Chilkat Peninsula and Islands, Alaska, as part of the larger Juneau Mining District study. About 4/5 of the area is within the Alaska State Chilkat and Chilkat Islands State Parks and not open to mineral entry. This study located four new (or previously unreported) gold- copper prospects. One of these, the Road Cut prospect, was examined by trenching, drilling and geophysics.

To focus the scope of this data release, we report only mined deposits and exploration prospects with past production, or resource and reserve estimates of 1,000 metric tons or more of cobalt. Cobalt has diverse uses because of its properties, which include ferromagnetism, hardness, wear-resistance, low conductivity, and high melting point. The primary uses for cobalt are in rechargeable battery electrodes, and in superalloys used to make gas turbine engines. In 2017, the United States had a net import reliance...
