| Deposit | TWO FLUOROSPAR DEPOSITS OCCUR IN THE FOOTWALL ROCKS BELOW A THRUST FAULT. IN THE UPPER, MAIN BODY, THE FLUORITE IS WHITE TO PALE GREEN AND FINE-GRAINED IN THE LOWER DEPOSIT, ADDITIONAL FLUORSPAR OCCURS AS A REPLACEMENT BODY THAT CONFORMS TO THE BEDDING BUT IS NOT DETERMINED WHETHER THE BEDDED DEPOSIT WAS CONTROLLED BY THE FAULT. THE FLUORSPAR IN THE BEDDED DEPOSIT IS MORE SILICEOUS AND LESS CALCAREOUS THAN THE MATERIAL IN THE UPPER DEPOSIT. FLUORITE OCCURS IN ZONE OF STRONGLY BRECCIATED AND SHATTERED ROCK TRENDING N5-10W. NUMEROUS HIGH-ANGLE STRUCTURES- EXPOSED IN PIT, LIMESTONE IS SILICIFIED AND REPLACED BY LATE--STAGE FLUORITE IN COARSELY CRYSTALLINE MASSES, WHITE, GREEN AN-D PURPLE IN COLOR. FOOTWALL OF MAIN FLUORITE ZONE IN PIT SHOWS- NUMEROUS HIGH-ANGLE STRUCTURES. ALSO, QUARTZ STOCKWORK VEININ-G AND SILICIFICATION OCCUR IN FOOTWALL BELOW WEST-DIPPING FAUL-TS. SOME GOOD JASPEROID WITH BRECCIA TEXTURE ASSOCIATED WITH F-LUORITE. |

IN 1953 A LONG ADIT WITH SEVERAL CROSSCUTS WAS DRIVEN BY KAISER ALUMINUM & CHEMICAL CORP. SOME DRILLING DONE BY ARROWHEAD SILICA CORP IN 1972. TWO FLUORSPAR DEPOSITS OCCUR IN THE FOOT WALL ROCKS A SHORT DISTANCE BELOW THE THRUST FAULT. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV |
