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.

Comment (Workings): MAP OF MINE AVAILABLE IN CALLAGHAN, 1936, P. 19. DEVELOPED BY 2 LEVELS . TWO ADITS AND SEVERAL PITS. MOST OF THE ORE WAS REMOVED FROM THE UPPER ADIT STOPE WHICH EXTENDS FROM UPPER LEVEL 45 FT TO SURFACE. 2 WINZES. IN 1983, SEVERAL OPEN SSW-TRENDING ADITS ON N-FACING SLOPE, ONE SHAFT AND SEVERAL LARGE DUMPS. . TWO ADITS AND SEVERAL PITS.

AT UPPER ADIT, HOST ROCK IS ORANGE WEATHERED QUARTZITE OR SILTY SANDSTONE WHICH FORMS 0.5-2 FT THICK BEDS STRIKING N10W, DIP 35 NE. THE ROCK ON THE DUMP IS SLIGHTLY LAMINATED VITREOUS GREY (FRESH) QUARTZITE WHICH SHOWS SOME CALCITE AND QUARTZITE VEINING. THE ROCKS ARE SILICIFIED, RECRYSTALLIZED, WITH SOME SERICITE IN MATRIX. IN GENERAL, THE QUARTZITES ARE COVERED WITH ABUNDANT IRON OXIDES AND YELLOW AND GREEN OXIDES OF PERHAPS AS, PB, FE, OR OTHER. SOME OF THE ALTERED QUARTZITES CONTAIN IRON-STAINED QUARTZ- AND CALCITE-FILLED VUGS. ADITS LINE UP ALONG N- TO NE-TRENDING VEIN SYSTEMS, WHICH APPARENTLY FOLLOW THE BEDDING OF THE HOST ROCKS.
