Satelite View

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

Comments
Comment (Location): SE 1/4 SEC. 9, UTM EST.
Comment (Deposit): TACTITE 200 FT. BY 70 FT.
Comment (Workings): SEVERAL SMALL PITS AND 2 SHORT ADITS
Comment (Geology): GEOL.DESC: MICA SCHIST EXPOSED IN WORKINGS NOT AT SURFACE
Comment (Workings): (1) THIS DESCRIPTION APPLIES TO VEINS AND NOT TO PLACERS. (2) PRODUCTIVE BELT EXTENDS 2 MILES EW ALONG STRIKE OF VEINS. OCCURRENCE OF SCHEELITE RANGES 3 MILES NS.
Comment (Reserve-Resource): THESE ARE PLACER RESERVES AND MIGHT BE MORE PROPERLY CONSIDERED AS RESOURCES. HOWEVER THERE IS MUCH ALLUVIUM WITH 1-1.5 LB. SCHEELITE/CUBIC YARD
Comment (Development): ECON.COM: SHORTAGE OF WATER FOR WORKING PLACERS
Comment (Geology): ROSAMOND SERIES CONGLOMERATE AND SANDSTONE (MIOCENE) PRESENT. ATOLIA QUARTZ MONZONITE (JURASSIC) CONTAINS MONZONITE AND DIORITE. UPPER MIOCENE DIABASE DIKES ARE PRESENT.
Comment (Deposit): ABOUT 8% OF THE PRODUCTION HAS COME FROM PLACER MINING IN THE ALLUVIUM - THE "SPUD PATCH" IS MOST FAMOUS AREA. MANY ATTEMPTS - MOSTLY UNSUCCESSFUL - TO RECOVER THIS SCHEELITE PLUS MINOR GOLD IN PLACERS.
