Lake Central Project

The Lake Central Project is a gold and silver mine located in Clear Creek county, Colorado at an elevation of 7,198 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.

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.

Land Status

Land ownership: Private
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 (Reserve-Resource): Sunshine files contain reports that may have dated or optimistic resource estimates of 488,000 tons of ore, assuming 2' avg. thickness of veins from tunnel level up to previously mined stopes.

Comment (Geology): The Lake vein is a fissure vein up to 5 feet in width, that strikes NE and dips steeply NW, and contains mostly pyrite at the tunnel level. The Belman vein strikes NW and dips NNE, and contains quartz, pyrite, and chalcopyrite.

Comment (Location): Project to access Lake, Belman, and nearby veins at depth, via Big Five (Central) tunnel just west of Idaho Springs. The target area lies in NW/4 sec. 26, T 3 S, R 73 W, about 1-1/2 miles NNW of Idaho Springs.

Comment (Deposit): INFORMATION FROM OME REPORT, DOCKET NO. 6022, DATED 1959. AT TIME OF THE REPORT, THERE HAD BEEN NO PRODUCTION FROM THE MI THE FORM OF URANIUM. AN EARLY GOLD-SILVER-COPPER-LEAD PRODUC CLAIMS WERE CONTROLLED BY CLEAR CREEK MINING CO., COLO., AT TIME OF THE REPORT. THE CLAIMS ARE IN SECS. 23, 26, AND 35, R. 73 W., 6TH P.M., AND ON THE 7-1/2 MINUTE MAP, IDAHO SPRIN CLAIMS ARE WELL DEVELOPED WITH UNDERGROUND WORKINGS. INCLUDE THE OME REPORT ARE LOCATION AND MINE MAPS. THE OME REPORT CO THAT DUE TO GOOD CHANCES FOR FINDING COOPER (BUT NOT URANIUM ITS, ASSISTANCE FOR EXPLORATION BE GRANTED.

Comment (Commodity): CGS Bull.40 lists uranium here (US BuMines unpub. rept.).
