| Basis for focus area |
Carlin-type gold districts in Nevada. |
| Identified resources |
Identified resources for gold; historical production of antimony and gold. |
| Production |
Unknown. |
| Status |
Past and active mining and exploration for gold. |
| Estimated resources |
Enormous resources for gold, none defined for antimony. |
| Geologic maps |
Crafford (2010), scale 1:500,000; Stewart and Carlson (1978), scale 1:500,000. |
| Geophysical data |
Inadequate aeromagnetic and aeroradiometric coverage. |
| Favorable rocks and structures |
Paleozoic limey siltstones and silty limestones. |
| Deposits |
Many examples in MRDS with Au and Sn; for example, Dee Gold mine (MRDS dep_id: 10047016), Morning Glory prospect (MRDS dep_id: 10044099), White Caps mine, Blue Eagle Group (MRDS dep_id: 10045385). |
| Evidence from mineral occurrences |
MRDS. |
| Geochemical evidence |
Antimony is present in Au-bearing pyrite and in paragenetically late stibnite. |
| Geophysical evidence |
Unknown. |
| Evidence from other sources |
Berger and others (2014); Goldfarb and others (2017). |
| Cover thickness and description |
Surface and underground gold mining, exploration to depths of 2 km for gold. |
