| Basis for focus area |
Mapped dolomites in Idaho from Horton and others (2017). |
| Identified resources |
Historical production of lead, silver, and zinc. |
| Production |
The Kimmel and Leadville (Sunset) mines produced about 13,444 tons of ore containing significant Pb and Ag, with minor Cu, Zn, and Au. |
| Status |
Past mining. |
| Estimated resources |
Unknown. |
| Geologic maps |
Evans and Green (2003), scale 1:100,000; Ruppel and Lopez (1988), scale 1:200,000. |
| Geophysical data |
Inadequate Rank 3 to 4 aeromagnetic and Rank 4 aeroradiometric coverage. |
| Favorable rocks and structures |
The principal mines in the district are Pb-Ag replacement deposits in Mississippian limestone; a few small mines explore deposits of secondary copper minerals in fractures and in thrust fault breccias (Ruppel and Lopez, 1988). |
| Deposits |
Kimmell mine (MRDS dep_id: 10011682), Sunset mine (MRDS dep_id: 10105783). |
| Evidence from mineral occurrences |
MRDS; Idaho Geological Survey polymetallic sites with Mg. |
| Geochemical evidence |
One 43-ton test shipment from the Kimmel No. 2 level assayed 5.2% Pb and 3 oz/ton Ag. |
| Geophysical evidence |
Unknown. |
| Evidence from other sources |
Unknown. |
| Cover thickness and description |
Exposed at the surface. |
