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.

Comments

Comment (Geology): PROSPECT LIES JUST NORTH OF AN EAST-WEST FAULT JUXTAPOSING THE LEACH CANYON TUFF TO THE SOUTH AND THE CALLVILLE LIMESTONE TO THE NORTH. THE NORTH SIDE OF THE FAULT IS BROADLY SILICIFIED IN AN EAST-WEST BELT

Comment (Location): INFO FROM LAND.ST :(1975)

Comment (Development): OWNERSHIP OF THE PROPERTY CHANGED IN 1914 FROM THE BULL VALLEY GOLD MINES COMPANY TO JOHN Z. ALGER. THE AREA HAS BEEN EXPLORED IN RECENT YEARS FOR PRECIOUS METALS, ESPECIALLY SINCE 1978.

Comment (Deposit): THE DEPOSIT CONSISTS OF A FAULT ZONE, STRIKING N 23 W AND DIPPING 88 DEGREES TO THE NE, ALONG WHICH OCCURS STRONG BRECCIATION, SILICIFICATION, AND IRON OXIDE STAINING. THE SILICIFIED BRECCIA ZONE HAS BEEN CALLED A VEIN OR A FISSURE VEIN IN PREVIOUS REPORTS. THE SILICIFIED BRECCIA ZONE IS EXPOSED IN THE CUT AND RANGES FROM 4 FEET TO 1 FOOT IN WIDTH. IT COMPRISES THE HANGING WALL OF THE HASSAYAMPA FAULT. SILICIFIED BRECCIA IS DARK BROWN WITH STRONG LIMONITE STAINING AND JAROSITE. THE FOOTWALL CONSISTS OF A 10-FOOT WIDE ZONE OF ARGILLIZED FAULT GOUGE. A SMALL CROSS-FAULT IS PRESENT AT N 72 W, 55 SW WITH MINOR DISPLACEMENT.

Comment (Workings): WORKINGS CONSIST OF A SHAFT AND AN ADJACENT CUT. THE SHAFT HAS BEEN FILLED BY THE CONSTRUCTION OF A ROAD. THE SHAFT WAS 110 FEET DEEP WITH A 16-FOOT LONG CROSSCUT AT THE BOTTOM. THE CUT IS 50 FEET IN LENGTH
