Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Commodity): ALTHOUGH THE CLAIM IS IN A MINERALIZED AREA, IT SHOWS LITTLE VALUE
Comment (Location): INFO FROM LAND.ST :(1968)
Comment (Workings): PROSPECT HOLE 5 FEET WIDE BY 30 FEET LONG TO A 6 FOOT FACE. NO VEIN WAS EXPOSED
Comment (Geology): AN APLITE DIKE CUTS THRU THE CLAIM AND IS PROBABLY A POST-MAGMATIC OCCURENCE FROM THE BOULDER BATHOLITH
