Comments

Comment (Deposit): Discovery Year: EARLY1900'S?

Comment (Location): ABOUT 1 MILE SOUTH OF THE ROSEBUD MINE WHERE THE ROAD TO THE ROSEBUD MINE FORKS OFF ROSEBUD CANYON ROAD. ; INFO FROM LAND.ST :(1972)

Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1984

Comment (Deposit): VEIN FAULT IN MAIN ADIT BEARS ALMOST EW, SUNK IN RHYOLITE. SAMPLE 1800 WAS TAKEN FROM VEIN WITHIN LARGE LOWER ADIT ABOUT 50 FT FROM THE ENTRANCE. VEIN VARIES IN WIDTH AND STRIKE, BUT IS CLOSE TO VERTICAL. IT IS VERY PUNKY EXCEPT FOR AREAS OF SILICIFICATION, WITH OTHER AREAS VUGGY AND BRECCIATED.

Comment (Workings): ADITS AND SHAFTS ON WEST SIDE OF MOUTH OF ROSEBUD CANYON. SURFACE BUILDINGS ARE FALLING DOWN.
