Comment (Deposit): THIS RECORD HAS BEEN REVISED TO INCLUDE INFORMATION FROM RECORD NUMBER W700405, WHICH HAS BEEN DELETED.

Comment (Development): SEVERAL ROTARY DRILL HOLES ARE ON LOCATION IN 1982. MINING BEGAN A FEW YEARS LATER. MULTIPLE BENCH; CONSTRUCTION.

Comment (Deposit): ENTIRE OUTCROP AT PROPERTY IS 40 METERS DIA. AND CONSISTS OF BLACK CHERTAND ARGILLITE, CUT BY STOCKWORK OF QUARTZ, VEIN, BRECCIA FILLING AND VEINLETS. VEINS CONTAIN SUGARY QUARTZ WITH SMALL DRUSY OPENINGS. REPLACEMENT TEXTURE OF QUARTZ AFTER LAMELLAR CALCITE IS QUITE COMMON, AS IS A CRUSTIFORM BILATERALLY SYMMETRICAL BANDING ACROSS THE VEINS. VEIN MATERIAL IS COMMONLY IRON-STAINED. IN BETWEEN VEINS, HOST ROCK IS CUT BY 3 MM- ICM VEINLETS OF QUARTZ. SOME BRECCIA ZONES ADJACENT TO VEINS WITH OPEN-SPACE TEXTURE MAY BE FAULT BRECCIAS. BARIET OCCURS AS SMALL ROSETTES IN CAVITIES IN SOME SAMPLES.

Comment (Workings): SURFACE - OPEN PIT ; OLDER WORKINGS CONSIST OF 5-6 M SHAFT AND PITS

Comment (Geology): A REPLACEMENT TEXTURE OF QUARTZ AFTER LAMENAR CALCITE IS QUITE COMMON FE OXIDE STAIN OF VEIN COMMON. WALL ROCK IS CUT BYQUARTZ VEINLETS COMMONLY CONTAINING CHUNKS OF WALL ROCK FROM HYDROTHERMAL BRECCIATION. BARITE ROSES OCCUR IN SOME VUGS.

Comment (Location): MINE NORTH OF HIGHWAY 95; DISCOVERY OUTCROP-BLACK ROCK PROSPECT IS JUST SOUTH OF HIGHWAY. UTM IS TO MINE AREA. ; INFO FROM LAND.ST :(1972)
