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 (Production): 7 OZ. AU, 3 OZ. AG IN 1940-41
Comment (Deposit): SAMPLE 2854 WAS CHIPPED FROM A VEIN AT THE HEAD OF THE CANYON THAT MAY HAVE BEEN ONE OF THE SOURCES OF THE GOLD IN- THE PLACERS. THE VEIN WAS A QUARTZ, IRON-STAINED BRECCIA THAT- HAD BEEN PROSPECTED HISTORICALLY BY HAND AND BY A DOZER. SAMP-LE 2855 WAS FROM 2 VERY INTERESTING- LOOKING VEIN MATERIALS WI-THIN THE PLACER MATERIAL, WHICH INCLUDED QUARTZ WITH SULFIDES -AND POSSIBLE AU, AG. SAMPLE 2856 WAS FROM AN APPARENT TUNGSTEN- PROSPECT ON A RIDGE OVERLOOKING THE PLACERS.
