Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Deposit): GRADE DECREASES WITH DEPTH. AT LIMIT OF WORKINGS (500-FT DEPTH), ORE PRODUCED $14.00/ST FROM COMBINED GOLD AND SILVER VALUES IN 1911. THE RATIO OF GOLD TO SILVER VALUE WAS 58:1, THE PRICE OF GOLD WAS $20.67/TR OZ, AND THE PRICE OF SILVER WAS $0.54/TR OZ. WITH THE PRECEDING INFORMATION, THE ORE GRADE AT DEPTH CAN BE ESTIMATED AT ABOUT 0.67 TR OZ/ST AU AND ABOUT 0.44 TR OZ/ST AG. AT THESE GRADES, THE "LARGE TONNAGES" REFERRED TO BY WILSON, CUNNINGHAM, AND BUTLER (AZ BUR. MINES BULL. 137, 1934) CERTAINLY CONSTITUTE A SIGNIFICANT RESOURCE.
Comment (Geology): ALTERATION ALSO INCLUDES CHLORITIZATION. LENGTH OF MINERALIZATION IS AT LEAST 1067 M (3500 FT).
