Regional locations and general geologic setting of known deposits of major nonfuel mineral commodities. Originally compiled in five parts by diverse authors, combined here for convenience despite likely inconsistencies among the regional reports.

Approximate locations and short descriptions of mines, deposits, and districts where critical minerals are found. The critical minerals are discussed in USGS Professional Paper 1802 many of these locations are described in further detail in that report.

Information on porphyry copper deposits from around the world with grade and tonnage models, a general classification based on geologic setting, mineralogy, with data allowing locations of these deposits to be plotted using GIS.

Mineral facilities and operations outside the United States compiled by the National Minerals Information Center of the USGS.
