| Deposit | THE PROPERTY WAS EXPLORED PRIOR TO 1955, BUT NO MINING WAS DONE UNTIL ROAD HAD BEEN BUILT TO IT FROM THE GRANITE CREEK MINE IN 1955, WHEN OPEN-PIT MINING BEGAN. IT CONSISTS OF FIVE UNPATENTED CLAIMS. WORKINGS INCLUDE 2 SHORT ADITS, TRENCHES, AND OPEN CUTS. 300-350 TONS OF 1.7% WO3 ORE AND 1000 TO 1300 TON S OF 0.5% WO3 ORE WERE ESTIMATED TO BE PRESENT IN 1946, AS WELL AS 6000 TO 12,000 TONS OF 0.3% WO3 OR LESS ORE POSSIBLE ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT |
| Deposit | THE DEPOSIT IS ON THE WEST SIDE OF THE SOUTH PART OF THE GRANODIORITE STOCK NEAR THE CREST OF THE RANGE. THE CONTA-CT ZONE BETWEEN THE STOCK AND THE SEDIMENTARY ROCKS IS HIGHLY -IRREGULAR. SLIDE ROCK COVERS MUCH OF THE SURFACE IN THE VICINI-TY OF THE MINE AND EXPOSURES ARE POOR. SMALL AND DISCONTINUOUS- TACTITE BODIES OCCUR WHERE THE THIN LIMESTONE BEDS, IN ARGILL-ITE AND HORNFELS, ARE TRUNCATED BY THE GRANODIORITE STOCK OR B-Y IRREGULAR APOPHYSES. THE TACTITE BODIES MINED WERE FROM A FE-W FEET TO 25 FEET WIDE AND PROBABLY AVERAGED ABOUT 20 FT. THE -TUNGSTEN CONTENT RANGED FROM 0.1 % WO3 TO 3.34 % BUT PROBABLY -AVERAGED ABOUT 0.5 % WO3. WORKINGS EXTEND ALONG 1200 FT STRIKE |
