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 (Deposit): SIX MAJOR VEINS 1-24 INCHES THICK AND CONSIST PRINCIPALLY OF BRECCIATED WALL ROCK AND VARYING AMOUNTS OF QUARTZ JAMESONITE OCCURS AS BLEBS AND SMALL PODS, EXCEPT IN THE DEEPER WORKINGS WHERE IT HAS BEEN CONVERTED TO BINDHEIMITE AND OTHER SB OXIDES. SMALL ADITS IN THE WEST GROUP ARE ALONG N20E PARALLEL STRUCTURES. MANY OF THE VEIN SYSTEMS ARE EXPOSED AT THE SUR-FACE ALONG OPEN PROSPECTS AND STOPES
