Probabilistic estimates of the amounts of undiscovered gold, silver, copper, lead, and zinc in conventional types of mineral deposits in the United States.
General explanation of the processes that affect the availability, transport, and fixation of metals and the generation of acidic waters from mineral deposits
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.
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.
These regional reports are designed to inform the non-earth scientist about the regional locations and general geologic setting of known deposits of major nonfuel mineral commodities.
Includes deposits, occurrences, and prospects; drill core logs and measured sections; and spatial databases for geologic maps, untested exploration areas, and permissive tracts for undiscovered mineral deposits.
The Barite Hill deposit was mined from 1990 to 1994, and, during this time, approximately 1,835,000 grams of gold and 3,390,280 grams of silver were produced.
