Information leading to the delineation of this focus area

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.
Authors Albert H. Hofstra, John L. Muntean.
New data needs Geologic mapping, geophysics.
Geologic mapping and modeling needs Updated geologic mapping.
Geophysical survey and modeling needs High resolution aeromagnetic and aeroradiometric coverage.
Digital elevation data needs Lidar variable across a large, multipart focus area.
