Comments

Comment (Location): UTM IS FOR SAMPLE SITE 2929, ADIT; UTM FOR SAMPLE SITE 2928 IS N4515870, E331020; UTM FOR SAMPLE SITE 2930 IS N4515670, E330590. . INFO FROM LAND.ST :(1972)

Comment (Development): LOTS OF RECENT LOCAL PROSPECTING ACTIVITY, STAKING, BUT NO ACTIVITY AT TIME OF EXAMINATION IN 1985. MANY GENERATIONS OF CLAIM POSTS. ROAD IS VERY OLD AND BUILT BY HAND.

Comment (Deposit): METAVOLCANICS ON EAST AND GRANODIORITE ON WEST. EXTENSIVE QUARTZ VEIN SYSTEM WITH MOST WORKINGS IN THE GRANODIORITE, ON N-TRENDING VEINS. SMALL ADIT FOLLOWS A N10W VEIN DIPPING 10 W; THIS VEIN WAS OPEN-STOPED ALONG E SIDE OF HILL FOR 200 FT (SAMPLE 2928). ADIT AND INCLINE NEAR MILLSITE EXPLORED SEVERAL VEINS (N10W) IN GRANODIORITE (SAMPLE 2929). LOCALLY, THERE ARE PODS OF BLACK TOURMALINE ADJACENT TO OR NEAR CONTACT ZONES. VEIN MATERIAL HAS BEEN SORTED AND STACKED IN PILES. ONLY VISIBLE MINERALIZATION IN VEINS IS PYRITE AND FE OXIDES.

Comment (Workings): ADITS, OPEN STOPES, MINOR TRENCHING, PROSPECTS, LOADING FACILITY, REMNANTS OF A CRUSHING AND SORTING MILL.
