This study delineated permissive areas for undiscovered sandstone 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.

Discusses the physical properties of frac sand, its geologic origin and formation contributing processes, its use in industry, consumption history and a global outlook. US / Canadian producers are detailed and potential other sources delineated in a GIS

Regional locations and estimates of the probable amounts of undiscovered resources of copper, platinum-group elements, and potash in selected types of mineral deposits to depths of 1 to 3 kilometers below the surface of the earth worldwide.

This report provides a script developed in open-source statistical software, R, that aggregates undiscovered deposit estimates of a given type assuming some degree of correlation among aggregated areas, provided a user-specified correlation matrix.

This report describes key features; identifies tectonic-sedimentary environments; illustrates geochemical, geophysical, and geoenvironmental characteristics; evaluates deposit formation; presents exploration and assessment guides; and lists knowledge gaps

Rock property measurements including density, magnetic susceptibility, and radiometric concentrations to understand structural and geophysical relationships associated with rare earth element mineral deposits. Data are provided in CSV format.
