The Erie No. 33 Prospect is a uranium mine located in Saguache county, Colorado at an elevation of 10,761 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.

Comments
Comment (Workings): APPROX. 300 FT OF BULLDOZED TRENCHES
Comment (Deposit): HOST ROCK IS INTERPRETED AS JASPEROID FORMED BY METASOMATIC REPLACEMENT OF LIMESTONE (BELDEN FM AS INTERPRETED BY RANSPOT, MISSISSIPPIAN LEADVILLE LIMESTONE AS INTERPRETED BY OLSON). AROUND IRON-RICH CORE IS ZONE OF SILICIFIED LIMESTONE GRADING INTO UNALTERED LIMESTONE. JASPEROID CORE TRUNCATED ON EAST BY CHESTER FAULT AND BOUNDED ON NORTH AND SW BY BRANCH FAULTS. URANIUM MINERALIZATION PROBABLY INTRODUCED BY SILICA-RICH SOLUTIONS ALONG SMALL FRACTURES AFTER REPLACEMENT OF LIMESTONE. SIMILARITY WITH OTHER JASPEROIDS SUGGESTS PRESENCE OF BASE-METAL SULFIDE BODY AT DEPTH
Comment (Location): ON SOUTH SIDE OF LIME RIDGE APPROX. 2500 FT NORTH OF PITCH MINE AND 3.1 MILES NW OF MARSHALL PASS ; INFO FROM LAND.ST :1976
