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): (LAND STATUS AND ADMINISTRATIVE AREA LOCATIONS CALCULATED USING GIS OVERLAY ANALYSIS FOR SAN JUAN N. F.). ON HILLSIDE NORTH OF SULPHUR CREEK AND ARGONAUT MINE AND WEST OF IRON CLAD MINE (UNSURVEYED SECTION). ELEV AND LAT-LONG GIVEN ARE FROM MCKNIGHT, 1974, PL. 1 (1930 BASE). ; INFO FROM LAND.ST :1975

Comment (Deposit): LOWER HERMOSA FM INTRUDED BY HORNBLENDE LATITE PORPHYRY. SCATTERED POCKETS OF NATIVE AU AND SLIGHTLY AURIFEROUS PYRITE OCCUR IN CHALE BRECCIA ABOVE BEDDING FAULT 15 FT ABOVE PORPHYRY SILL, IN FRACTURES TERMINATING ON BRECCIA, IN BEDDING SEAM AT TOP OF FRACTURES 30 FT ABOVE SHALE BRECCIA. CALCITE AND LOOSE QUARTZ ARE SPARSE. DEPOSIT IS UNIQUE IN DISTRICT IN THAT ALL VALUES ARE FREE AU, BUT DEPOSIT WAS NOT VERY PROCDUCTIVE DUE TO ERRATIC OCCURRENCE OF AU POCKETS.

Comment (Workings): TUNNEL DRIVEN GENERALLY WEST FOR 160 FT, THENCE SW FOR 335 FT.
