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 (Location): NEAR THE HEAD OF EDDY CREEK

Comment (Development): 11 PATENTED CLAIMS, 6 UNPATENTED CLAIMS. DURING 1961 DEVELOPMENT WAS RENEWED AND SEVERAL CAVED ADITS WERE REOPENED; DIAMOND DRILL HOLES WERE ALSO MADE.

Comment (Deposit): MINERALIZATION OCCURS IN NW STRIKING QUARTZ VEINS THAT RANGE IN WIDTH FROM A FEW INCHES TO 8 FEET. MANY OF THE VEINS DIP NE, BUT A FEW TEND TO BE VERTICAL. THE VEINS OCCUR IN BOTH THE DIORITE AND THE ARGILLITE. MINERALIZATION IS VERY MINOR IN THE QUARTZ MASSES, CONSISTING MOSTLY OF IRON OXIDE AND A FEW SMALL GRAINS OF GALENA.

Comment (Workings): WORKINGS CONSIST OF SEVERAL CAVED ADITS AND DISCOVERY PITS.

Comment (Geology): ARGILLITE WEATHERS A DEEP BROWN AND HAS A BANDED APPEARANCE. ARGILLITE GENERALLY STRIKES N 30 TO 40 DEG W AND DIPS 29 DEG TO 85 DEG SW.
