General comments

Subject category Comment text
Deposit QUARTZ VEINS IN GRANODIORITE WERE MINED VIA A SMALL ADIT, AND MATERIAL WAS MILLED BY A GRINDING AND CRUSHING FACILITY AND WASHED IN A NEARBY STREAM. VERY SMALL CRUDE ONE-MAN OPERATION, BUT RESEMBLES A MINE- PROBABLY HAD SOME SMALL UNREPORTED PRODUCTION.
