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 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 (Location): MINE LIES ON SW SLOPE OF EMPIRE MOUNTAIN EAST OF YELLOWSTONE GULCH AND 0.5 MILE NNE OF CAPITOL CITY SITE. ALTHOUGH PROPERTY HOLDINGS AS OF 1968 INCLUDED THE CAPITOL CITY AND SILVER CHORD CLAIMS, THIS DESCRIPTION IS LIMITED TO CZAR WORKINGS. SEE RECORDS FOR CAPITOL CITY MINE AND FOR SILVER CHORD MINE FOR RESPECTIVE DESCRIPTIONS. ; INFO FROM LAND.ST :1977
Comment (Production): PARTIAL PRODUCTION RECORD. FIGURES AND EXACT YEARS OF PRODUCTION PRIOR TO 1904 UNKNOWN. PRODUCTION FOR 1953-1956 IS FROM MINERAL YEARBOOKS, WHICH CITED CZAR AS ONLY ACTIVE MINE IN GALENA DISTRICT; THUS, ABOVE FIGURES FOR CZAR MINE ARE SAME FOR DISTRICT OUTPUT IN THOSE YEARS. NO REPORTED PRODUCTION AFTER 1956.
Comment (Deposit): MINE LIES NW OF LAKE CITY CALDERA RIM IN UNCOMPAHGRE CALDERA INFILL ROCKS, CONSISTING OF EUREKA MEMBER RHYOLITE AND BURNS MEMBER QUARTZ LATITE. WEST OF MINE, THIS SEQUENCE IS INTRUDED AND ALTERED BY MONZONITE PORPHYRY AND RHYOLITE PLUGS. VEIN IN UPPER LEVEL TRENDS N 6 E, 60 TO 80 SE, AND IS COMPOSED OF TWO SMALL VEINS, NEITHER OVER 2 FT WIDE (CDM REPORTS VEIN WIDTH OF 5 FT); AVERAGE ORE COURSE IS 3 INCHES, VARYING FROM 0.5 TO 8 INCHES. GALENA THICKLY INTERSPERSED WITH SPHALERITE, BOTH FREQUENTLY CUTTING THROUGH THIN LAYER OF CHALCOPYRITE. VEIN LIES IN SLACK'S (1980) QUARTZ/BASE-METAL ASSEMBLAGE, INNER QUARTZ-CHALCOPYRITE ZONE.
Comment (Workings): MINE DEVELOPED BY TWO TUNNELS DRIVEN GENERALLY NORTH. 100-FT RAISE FROM LOWER LEVEL CONNECTS WITH SHAFT FROM SURFACE TO 120 FT BELOW FIRST LEVEL. 125-FT NEWER CROSSCUT LOCATED 1200 FT BELOW OLDER WORKINGS.
