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 (Deposit): WORKINGS ARE ALONG CONTACT OF OLDER SEDIMENTS AND GRANITE. THERE APPEARS TO BE ORE PILED NEXT TO THE SHAFT. MATERIAL CONSISTS OF CALCITE RICH, MN-STAINED ORE WITH SOOTY PYROLUSITE, WAD. MOST OF THE MINERALS ARE HIGHLY OXIDIZED WITH COPPER, HEMIMORPHITE?, TETRAMEDRITE AND WHAT APPEARS TO BE YELLOW-GREEN LEAD OXIDES.
