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

Comment (Location): TOWNSHIP UNSURVEYED. UTM COORDINATES GIVEN FOR CARD ARE FOR THE PORTAL OF THE SUPRISE TUNNEL. UTM COORDINATES FOR OTHER PROMINENT TUNNELS ARE AS FOLLOWS: MORMAN TUNNEL 4488150 N, 487100 E, TREE TUNNEL-4488350 N, 487220 E, WYOMING TUNNEL-4488450 N, 487350 E, LADY ANNIE TUNNEL 4488550 N, 487350 E, MIDWEST TUNNEL 4487900 N, 487500 E ; INFO FROM LAND.ST :1983
Comment (Production): PRODUCTION FOR THE YEARS 1873 TO 1876 ARE RECORDED, BUT PRODUCTION WAS STEADY
Comment (Development): MILLER MINE WAS LARGEST IN DISTRICT, OPERATED CONTINUOUSLY FROM 1870 TO 1876
Comment (Deposit): DEPOSITS ARE OF REPLACEMENT ORIGIN. SIX TO EIGHT ORE BODIES WERE DISCOVERED. ORE BODIES ARE CONFORMABLE TO BEDDING, ELONGATE IN AN EAST WEST DIRECTION, AND PRIMARILY HOSTED BY HIGHLY SHATTERED MAXFIELD LIMESTONE. ENTIRE MINE AREA IS 1200 FT LONG BY 400 FT WIDE. MINERALIZING SOLUTIONS CAME UP ALONG EAST STRIKING FISSURES AND REPLACED LIMESTONE. OXIDATION HAS BEEN EXTREME
Comment (Workings): 13 ADITS, ONE SHAFT, AND ONE PROSPECT PIT SHOWN ON MAP. LOCATIONS OF PROMINENT TUNNELS GIVEN UNDER LOCATION COMMENTS SECTION. NAMES OF LESS PROMINENT TUNNELS ARE UPPER WYOMING, CAR, ROCK, SHAMROCK, AND SARCHFIELD. WORKINGS CONSIST OF THESE TUNNELS, INTERCONNECTED BY RAISES, SHAFTS, AND INCLINES, AND EXTENSIVE STOPES. MINE MAP PROVIDED BY CALKINS AND BUTLER, 1943, PLATE 50
Comment (Geology): HIGHLY SHATTERED MAXFIELD LIMESTONE IS MAIN HOST FOR REPLACEMENT ORE. ORE IS HIGHLY OXIDIZED
