This report is one of several Bureau of Mines reports concerning mineral development potential of the Chugach National Forest, AK. Anomalous data for selected strategic and critical minerals including antimony, chromium, cobalt, fluorspar, gallium, manganese, nickel, quartz crystals, tin, and tungsten were compiled from previously published Bureau reports and unpublished Bureau data. Deposits containing anomalous quantities of these commodities were identified and given mineral development potential ratings. Moderate mineral development potential exists for two manganese, three nickel, and one cobalt deposit. Cobalt, gallium, and nickel could be produced as byproducts should copper deposits such as those on Latouche and Knight Islands be developed. Low mineral development potential exists for antimony, chromium, fluorspar, and tungsten, and other cobalt, manganese, and nickel deposits. The mineral development potential for tin and quartz is unknown.
