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 (Workings): DEVELOPED BY 2 GROUPS OF WORKINGS 800 FEET APART AND TOTALLING 1000 FEET OF CROSSCUTS AND DRIFTS AMONG FOUR ADITS. 1891 OUTPUT WAS $15,000 IN SILVER AND $3400 IN GOLD.
Comment (Geology): YOUNGER (TERT?) GRANODIORITE PORPHYRY DIKES CUT BOTH THE QUARTZ DIORITE AND INTRUDED ARGILLITE. MINERALIZATION OCCURS IN NARROW GASH FRACTURES ALONG THE FOOTWALL OF ONE OF THE PORPHYRY DIKES. ; GEOL.DESC: COUNTRY ROCKS ARE CUT BY QUARTZ - DIORITE DIKES. TWO PERIODS OF QUARTZ DEPOSITION, THE FIRST ACCOMPANYING THE MINERALIZATION. LARGE AMT. OF CALCITE AND GREEN COPPER STAIN. LIMESTONE BAND CUTS ARGILLITE A LITTLE NORTH OF PROPERTY.
Comment (Location): SW 1/4
Comment (Production): LITTLE DATA AVAILABLE; 1891 OUTPUT WAS $15,000 IN SILVER AND $3400 IN GOLD.
