Sediment hosted gold deposits in Nevada were first mined in the 1960s from open pit mines with large tonnage and low grade resources. Since that time, continuing exploration and discovery have identified extraordinary resources, and together these deposits now form the second-largest gold endowment on Earth, surpassed only by the Witwatersrand Gold Fields of South Africa. The data herein are part of a larger U.S. Geological Survey (USGS) project to develop an updated geospatial database of mines, mineral deposits and mineral regions in the United States. The point and polygon layers within this database represent locations of mines, mineral occurrences (which includes deposits and prospects), and mining...

The USMIN Project is multi-year project of the USGS Mineral Resource Program (MRP) whose objective is to develop a comprehensive geospatial database of the mines, mineral deposits and mineral districts of the United States. This database builds upon MRP projects which date back to the late 1960’s and will provide data that will be of value to other parts of the USGS, other federal and state agencies and the general public. Mine Features, which are defined as “a single human-made object or disturbance associated with mining, such as a shaft or adit (vertical or horizontal opening), tailings, machinery and facilities, etc. A mine can be comprised of one or more features.” are a major component of the database....
