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

Comments
Comment (Deposit): SHALEY SEDIMENTS ARE BADLY BROKEN AND INTRUDED LOCALLY BY A RHYOLITE BRECCIA WHICH LOCALLY TRENDS N10W AND HAS MINOR CRYSTAL-RICH VEINS AND VEINLETS ASSOCIATED WITH IT. FROM A NE-TRENDING ADIT, THE WORKINGS HAVE STOPED THROUGH TO THE SURFACE ALONG THE STRIKE OF A VEIN, AT LEAST 4 TIMES OVER 300 FT. MUCH OF THE MATERIAL REMOVED FROM THESE WORKINGS ARE NOW ON THE HEAP LEACH PILE AT THE BOTTOM OF THE CANYON.
Comment (Workings): 2 GENERATIONS OF WORKINGS, HEAP LEACH FACILITY AT MOUTH OF CANYON.
