Mineral resource occurrences
A developing national-scale geospatial database that will be an authoritative source of information on the most important mines, mineral deposits, and mineral districts of the United States.
MRDS describes metallic and nonmetallic mineral resources throughout the world. Included are deposit name, location, commodity, and references. Some records include deposit description, geologic characteristics, production, reserves, and resources. It includes the original MRDS and MAS/MILS data.
Descriptions of mines, prospects, and mineral occurrences in Alaska.
Regional locations and general geologic setting of known deposits of major nonfuel mineral commodities.
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, and many of these locations are described in further detail in that report.
Mineral resource assessments
Estimates of the number and size of undiscovered mineral deposits in the US containing gold, silver copper, lead, and zinc.
Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.
Geologic map at 1:500,000 scale, digitized from USGS I-1865. Includes mines, prospects, and occurrences, permissive tracts for several mineral deposit types, and gravity anomaly contours.
