Information leading to the delineation of this focus area

Basis for focus area 15 km buffer around Barite Hill mining district (MRDS dep_id: 10226420).
Identified resources Historical production of gold and silver.
Production Barite Hill deposit (1990-1994): produced about 1,835,000 grams Au and 3,390,280 grams Ag (Clark, 1999).
Status Past mining.
Estimated resources Unknown.
Geologic maps Clark (1999), scale 1:100,000.
Geophysical data Inadequate Rank 4 aeromagnetic and aeroradiometric coverage.
Favorable rocks and structures Host rocks for the VMS deposits are sericitically-altered, felsic metavolcanic and metasedimentary rocks of the Late Proterozoic Persimmon Fork Formation, which consists of the Lincolnton meta-rhyolite and overlying lower and upper pyroclastic units.
Deposits Barite Hill (MRDS dep_id: 10226420).
Evidence from mineral occurrences MRDS.
Geochemical evidence The Barite Hill deposit is in the Lincolnton-McCormick district, which includes other mines and prospects for Au, Ag, Cu, Zn, Pb, Mn, as well as kyanite (Clark, 1999).
Geophysical evidence Unknown.
Evidence from other sources Geologic mapping.
Comments Known producer but limited spatial extent. Benefit of geophysical surveys not known.
Cover thickness and description Exposed bedrock to thin cover.

New data needs Geophysical data, geologic mapping, and geochemical analyses.
Geologic mapping and modeling needs 1:24,000 scale geologic mapping.
Geophysical survey and modeling needs High resolution aeromagnetic and aeroradiometric coverage. Aeromagnetic data expected to image mafic rocks and associated structures, radiometric data can help with geologic mapping in vegetated terrane; alteration may be imaged. Electromagnetic methods may help image sulfides.
Digital elevation data needs Lidar in progress.
