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.

Comment (Geology): THE PROPERTY IS UNDERLAIN BY THE POGONIP ANTELOPE VALLEY LIMESTONE, THE EUREKA QUARTZITE, AND THE HANSEN CREEK DOLOMITE. ALL THREE ORDORICIAN UNITS ARE MINERALIZED AND THE AREA IS CUT BY NUMEROUS HIGH ANGLE FAULTS AND HAS BEEN OVERTHRUST FROM THE WEST. THE FLUORITE & BERYL GENERALLY OCCURS IN QUARTZ VEINS WITH SERICITE, HOWEVER ORE ALSO OCCURS AT THE QUARTZITE-CARBONATE CONTACT AND AS DISSEMINATIONS. (PAPKE, 1979)
