The Caprock deposit is a lead and zinc mine located in Jackson county, Colorado at an elevation of 8,635 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Deposit): Workings consist of three trenches
Comment (General): Long's list of Significant Deposits OFR-98-206.
Comment (Geology): Classed as a sedimentary exhalative Zn-Pb-Ag deposit (USGS OFR 98-206), and as a stratabound sulfide deposit (USGS Map I-1971).
Comment (Production): Unknown, but probably none or very small.
Comment (Reserve-Resource): Exploration drilling from 1988 to 1991 defined a resource of 330,000 tons averaging 12.3% zinc plus lead, and an additional 440,000 tons averaging 4.7% zinc plus lead. (USBM MLA Report 13-94) Another source (Minerals Yearbook, 1991) says 783,000 tons of 7% zinc plus copper, lead, and silver, in addition to 328,000 tons of 12.3% zinc and lead.
