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 (Location): S 1/2 OF S 1/2 OF SEC 6; E SLOPE PUEBLO MTS.
Comment (Development): NO ACTIVITY IN 1984.
Comment (Deposit): MR. JACK DAVIS WHO LIVES AT THE MINE (1984) REPORTED THAT THE ORE WAS IN NARROW SEAMS OPENING INTO POCKETS OR VUGS CONTAINING GOLD. MANY OF THE SEAMS ARE FRACTURE-FILLING OR VEINLETS, BUT OTHERS ARE CLEARLY FAULT CONTROLLED AND PROBABLY GENETICALLY RELATED TO THE GRANITES. SAMPLE 2981 WAS FROM A NEWER EXPOSED PORTION OF THE MINE IN WHAT MUST BE A MINOR VEIN SYSTEM.
Comment (Workings): 7 ADITS (UP TO 490 FEET LONG) AND OTHER WORKINGS.
Comment (Geology): VEINS ARE 2 TO 6 FEET WIDE; VEIN FILLING IS ALTERED ANDESITE AND QUARTZ
