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): UTM IS TO SAMPLE SITE 2838. UTM OF SITE 2839 IS N 4484230, E379200 . INFO FROM LAND.ST :(1972)

Comment (Development): INACTIVE IN 1984

Comment (Deposit): A SERIES OF PROSPECTS ALONG A N-TRENDING VEIN SYSTEM IN SILTSTONE THAT BEARS N45E AND DIPS IRREGULARLY. SAMPLE 2838 WAS A BRECCIATED AND SILICIFIED PORTION OF A VEIN WITH PYRITE, ANTIMONY, AND POSSIBLY AG. SAMPLE 2839 WAS TO THE NORTH OF THE FIRST ONE BY ABOUT 300 YDS AND CONTAINED VISIBLE PYRITE AND OTHER SULFIDES IN A QUARTZ VEIN AND IN THE ADJACENT SILTSTONE HOST ROCK.
