As part of its critical and strategic minerals program, the Bureau of Mines is conducting a study of the gallium and germanium potential in Alaska. Gallium and germanium are produced as byproducts from the processing aluminum, zinc, coal, phosphate, and copper ores. Through literature research and geochemical analyses of selected mineral samples, 22 properties were identified as having high gallium or germanium concentrations. The potential for gallium and/or germanium in Alaska is currently unknown because of insufficient data. The study indicates that the most likely sources are from Alaska's large massive sulfide and coal deposits, but more sampling of all possible sources is needed.
