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): SIGN ON ROAD SAYS THIS IS CALLED ELDORADO. . INFO FROM LAND.ST :(1972)

Comment (Deposit): VEIN QUARTZ OCCURS AS SPOTTY, STOCKWORK-LIKE VEINS IN QUARTZITES. THE VEINS CONTAIN LIMONITE BOXWORKS AND DRUSY LIMONITE-COATED CAVITIES. THE VEINS APPEAR TO BE TENSION-GASH FILLINGS IN BOUDINS OF QUARTZITE SURROUNDED BY PHYLLITE. SIMILAR VEINING WAS OBSERVED AT THE NEARBY GOLDEN AMETHYST MINE. THE COMPOSITIONAL LAYERING, AND FOLIATION TRENDS N60E, 30NW. THE STOCK-WORK-LIKE GASH FILLINGS OCCUR IN A QUARTZITE LAYER. DRUSY QUARTZ CAVITIES ARE COATED WITH MN OXIDE STAIN AND FE OXIDE STAIN.
