Regional tracts of land where the geology is permissive for the occurrence of undiscovered porphyry copper deposits, with probabilistic estimates of undiscovered resources, along with tables of discovered deposits and prospects.
Includes deposits, occurrences, and prospects; drill core logs and measured sections; and spatial databases for geologic maps, untested exploration areas, and permissive tracts for undiscovered mineral deposits.
Multi-element geochemical analysis of host rock, ore, mine waste, flotation-mill tailings, slag, stream sediments, creek and adit waters, and leachates of mine waste and mill tailings.
Probabilistic estimates of the amounts of undiscovered gold, silver, copper, lead, and zinc in conventional types of mineral deposits in the United States.
Initial results of a petrographic, geochemical, and isotopic study of Mesozoic intrusive rocks and spatially associated Zn-Pb-Ag-Cu-Au prospects in the area.
This report presents geochemical analyses for 220 mostly altered and mineralized rock samples from the Red Dog Zn-Pb-Ag district in the western Brooks Range of northern Alaska.
