1998 Assessment of undiscovered deposits of gold, silver, copper, lead, and zinc in the United States
Estimates of the tonnages and amounts of contained metal in undiscovered deposits, mineral deposit types.
Geochemical and mineralogical characterization of the abandoned Valzinco (lead-zinc) and Mitchell (gold) mine sites prior to reclamation, Spotsylvania County, Virginia
Geochemical data for all solid sample media, along with mineralogical data, and results of weathering experiments on Valzinco tailings and field experiments on sediment accumulation in Knights Branch.
Geochemical and stable isotopic data on barren and mineralized drill core in the Devonian Popovich Formation, Screamer sector of the Betze-Post gold deposit, northern Carlin trend, Nevada
Detailed chemical and isotopic analysis of host and associated rocks within an area that is currently the largest producer of gold in the US. Part of a study of the hydrothermal activity leading to the formation of these gold deposits.
Quantitative mineral resource assessment of copper, molybdenum, gold, and silver in undiscovered porphyry copper deposits in the Andes Mountains of South America
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.
Case study of the environmental signature of a recently abandoned, carbonate-hosted replacement deposit: The Clayton Mine, Idaho
Multi-element geochemical analysis of host rock, ore, mine waste, flotation-mill tailings, slag, stream sediments, creek and adit waters, and leachates of mine waste and mill tailings.
Data base for undiscovered deposits of base and precious metals
Probabilistic estimates of the amounts of undiscovered gold, silver, copper, lead, and zinc in conventional types of mineral deposits in the United States.
Descriptive and grade-tonnage models and database for iron oxide Cu-Au deposits
Geological characteristics and resource estimates for 36 known deposits of this type worldwide.
Geochemical data for samples collected in 2008 near the concealed Pebble porphyry Cu-Au-Mo deposit, southwest Alaska
Chemical analysis of surface samples taken over a well known but concealed deposit to understand metal migration into the surface materials and to assess the power of surface sampling for detecting concealed deposits of this type.
Geology and nonfuel mineral deposits of Asia and the Pacific
Report on known and undiscovered nonfuel mineral deposits and resources of the Asia and Pacific region. Includes the age and type of rocks that contain the deposits, and regional exploration history.
Geology and resource assessment of Costa Rica
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.
