Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Geology): Age = Mississippian to Permian.
Comment (Reference): Primary Reference = This description
Comment (Geology): Geologic Description = The Surprise prospect consists of barite and sulfide mineralization in a Mississippian to Permian black shale horizon (J. Britton, oral communication, 1998). Sedimentary exhalative Pb-Zn type mineralization was intersected in 3 drill holes. Grades of approximately 3% combined lead and zinc occurred over intervals ranging from 10 to 24 feet.
Comment (Workings): Workings / Exploration = Three core holes were drilled on the prospect by GCO.
Comment (Deposit): Model Name = Sedimentary exhalative Zn-Pb (Cox and Singer, 1986; model 31a).
Comment (Exploration): Status = Inactive
