Comments

Comment (Deposit): DIMENSIONS ARE FOR STILLWATER COMPLEX. MINERAL DEPOSITS ARE THIN BUT LATERALLY EXTENSIVE. LARGE SIZE REFERS TO MINERALIZATION OF STILLWATER COMPLEX AS A WHOLE

Comment (Geology): IGNEOUS BEDROCK. PLACER GOLD LIKELY DERIVED FROM GOLD-QUARTZ VEINS IN AREA

Comment (Location): PLACERS ON PAYETTE RIVER ARE MOSTLY IN ADJACENT BOISE COUNTY. LOCATION GIVEN IS MOUTH OF PETERSON GULCH ABOUT 2.5 MI EAST OF MONTOUR

Comment (Development): EXCEPT FOR PRODUCTION FROM THE STILLWATER MINE, THERE HAS BEEN LITTLE PROFITABLE PRODUCTION

Comment (Workings): MOST MAJOR WORKINGS ARE UNDERGROUND, BUT EXTENSIVE TRENCHING HAS ALSO BEEN UNDERTAKEN. NUMEROUS DIAMOND DRILL HOLES HAVE BEEN DRIVEN, PARTICULARLY WITHIN THE JM REEF AND BANDED SERIES

Comment (Geology): AGE OF STILLWATER COMPLEX IS 2,705 +/- 4 MA BASED ON U-PB SYSTEMATICS ON ZIRCON-BADDELEYITE (PREMO AND OTHERS, 1990)

Comment (Deposit): SEE PAGE AND NOKLEBERG (1974) MAPS; PAGE, HAFFTY, RILEY (1972) ANALYSIS. ALSO SEE INDIVIDUAL RECORDS ; INFO.SRC : 1 PUB LIT

Comment (Reserve-Resource): 1 = MOD IS 2-10 TIMES RESERVES; 3 = SUBECONOMIC RESOURCES ALL ZONES, 4 = HYPOTHETICAL RESOURCES

Comment (Location): MOST OF AREA IS UNSURVEYED. LOCATION GIVEN IS APPROXIMATE FOR CENTER OF COMPLEX.

Comment (Production): ONLY PRODUCER OF PGE AS A PRIMARY COMMODITY IN THE CONTERMINOUS U.S.

Comment (Deposit): Discovery Year: 1860'S
