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.
This paper reports on a methodology that is used with estimates of undiscovered copper resources to evaluate the likely contribution that the predicted resources will make to mineral supplies in the foreseeable future.
This study delineated permissive areas for undiscovered porphyry copper deposits, compiled a database of known deposits and significant prospects, estimated undiscovered deposits within those areas and made probabilistic estimates of their metal content.
The site, on the Wind River Indian Reservation, has Eastern Shoshone and Northern Arapahoe tribes concerned about groundwater and soil contamination. This effort studies geochemical soil variation and compares concentrations with levels established by EPA
