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 report describes compilation and evaluation results of data from the USGS global mineral assessment including new descriptive mineral-deposit and grade and tonnage models and spatial databases for deposits and occurrences, ore bodies and open pits.
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.
For each deposit group, a map indicates relative density and certainty of favorable data. Tables list datasets used in analysis, parameters queried, their contribution to mineral estimates and allow further user analysis. GIS files enable spatial query.
