The Cleary Hill Mine is a gold and antimony mine located in Alaska.
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.

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 (Geology): VEINS ARE CRUSHED, RECEMENTED, CROSS FOLIATION OF SCHIST COUNTRY ROCK, AND ARE COMPLEXLY FAULTED, MAKING MINING DIFFICULT. VEINS CUT CREST OF LOW ANTICLINE, MUCH BROKEN BY AN INTRICATE SYSTEM OF FAULTS. FAULTS WITH THE GREATEST THROW STRIKE PARALLEL TO VEIN. ONE ZONE OF CONTORTED SCHIST AND GOUGE 30-40 FT. WIDE.
Comment (Location): USGS MF-413, LOC. 39. MINE MARKED ON LIVENGOOD (A-1) ALONG BEDROCK CREEK, A TRIBUTARY OF CLEARY CREEK. DEPOSITS EAST OF CREEK. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Development): MAJOR LODE-GOLD MINE IN DISTRICT-MINING REPORTED IN 1909-15, 1927, 1929-42, AND 1949. MILL ON PROPERTY. ELEVEN CLAIMS. MILL OPERATED ON ORE FROM OTHER MINES AT TIMES.
Comment (Deposit): LODE IS GOLD, STIBNITE, ARSENOPYRITE, PYRITE, SPHALERITE, GALENA, CHALCOPYRITE, JAMESONITE, COVELLITE, AND SCHEELITE BEARING VEINS CUTTING SCHIST IN FAULT ZONE. GOLD INTRODUCED AT TWO DIFFERENT STAGES; FIRST WITH QUARTZ AND SECOND WITH SULFIDES. GOLD IRREGULARLY DISTRIBUTED THROUGH VEIN MATERIAL IN VISIBLE PARTICLES UNCOMBINED WITH OTHER ELEMENTS. IN SOME PLACES THE VEIN IS RICHEST ADJACENT TO WALLS; IN OTHER PLACES IT IS RICHEST IN CENTER. SULPHIDE RICH PORTIONS OF VEINS ALSO CONTAIN GOLD. PRINCIPAL VEIN AVERAGES ABOUT 1 FT. IN THICKNESS; MAXIMUM THICKNESS 3 FT. SMALLER PARALLEL VEINS IN BOTH HANGING AND FOOTWALLS. AT LEAST ONE INTERSECTING VEIN IS LARGELY STIBNITE. THIN LIMESTONE BEDS IN SCHIST CONTAIN SCHEELITE. CASSITERITE IN WEATHERED VEIN MATERIAL.
Comment (Workings): OVER 3,000 FT. OF UNDERGROUND WORKINGS. MAIN TUNNEL DRIVEN ALONG VEIN FOR 1,280 FT.
