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.

Orebody
Form: THE DEPOSIT CONSISTS OF TWO OREBODIES-ONE IS A LARGE IRREGULAR, ROUGHLY CIRCULAR MASS AND THE OTHER A LONG, NARROW POD THAT TRENDS SOUTHEASTWARD. A LARGE, 100-FT CYLINDRICAL COLLAPSE STRUCTURE OCCURS IN THE SOUTHERN EDGE OF THE MAIN OREBODY: ORE IN THE COLLAPSE STRUCTURE IS DISPLACED ABOUT 20 FEET. THE ORE IS GENERALLY THICKER AND HIGHER GRADE THAN IN ADJACENT WALLS BUT SAME STRATIGRAPHIC ZONE
