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 (Workings): SOUTH TUNNEL DRIVEN GENERALLY EASTWARD FOR 200 FT, WITH 50 FT OF CROSSCUT AND 40 FT OF DRIFT. NORTH TUNNEL IS 200 FT TO NORTH, DRIVEN GENERALLY EASTWARD ALONG ESPERANZA FAULT ZONE FOR 370 FT. FIRST CROSSCUT DRIFT IS 56 FT LONG, DRIVEN AT RIGHT ANGLE TO TUNNEL 200 FT FROM PORTAL. SECOND CROSSCUT DRIFT IS 100 FT LONG, DRIVEN AT RIGHT ANGLE TO TUNNEL 300 FT FROM PORTAL. EVIDENCE OF OPEN PIT OPERATION.
Comment (Location): ON CRYSTAL HILL BETWEEN SANDERSON GULCH AND BIEDELL CREEK 8 MILES NW OF LA GARITA. PRINCIPAL MINE OPENING IS IN S2 SE NE SEC. 28 ; INFO FROM LAND.ST :1977
Comment (Deposit): BIEDELL STOCK IS PORPHYRITIC QUARTZ LATITE INTRUSIVE BOUNDED ON SE BY BIEDELL-KLONDIKE FAULT AND CUT BY SMALLER NORMAL FAULTS ON SW AND ON NORTH BY EAST-WEST-TRENDING ESPERANZA FAULT ZONE. OXIDIZED MANGANIFEROUS ORES FILL VOID SPACES IN BRECCIA PIPE; SOME VEIN-TYPE OCCURRENCE MAY BE PRESENT IN ESPERANZA FAULT ZONE. MINERALIZING FLUIDS PROBABLY ORIGINATED FROM BIEDELL-KLONDIKE FAULT. ADVANCED HYDROTHERMAL ALTERATION AROUND BRECCIA PIPE. SILVER HALOID AND FREE GOLD IN MANGANESE IS CONSIDERED TO BE A COCKADE ORE IN THE OXIDIZED AND LEACHED ZONE. PRESENCE OF CU CARBONATES (AT ESPERANZA MINE) SUGGESTS SULFIDE ZONE AND ENRICHMENT MAY LIE AT DEPTH.
