| Deposit | THE HOST ROCK ON THE LETA LYNN PROSPECT IS ARGILLIZED PURPLE ANDESITE PORPHYRY. A MINERALIZED FAULT ZONE ABOUT 16 FT WIDE, STRIKING N 20 W AND DIPPING 80 SW, CUTS ACROSS THE PROSPECT. ROCK AND VEIN MATERIAL IN THE FAULT ZONE ARE STRONGLY SILICIFIED. FLUORSPAR OCCURS IN IRREGULAR VEINS (8 TO 10 IN WIDE) AND PODS ALONG THE NW TRENDING FAULT. THE PODS AND VEINS CONTAIN COARSELY CRYSTALLINE FLUORITE, WITH MILKY QUARTZ, AND MINOR AMOUNTS OF PYRITE AND MN-OXIDES. ANDESITE BRECCIA IN THE FAULT ZONE IS PARTIALLY REPLACED BY FINELY CRYSTALLINE FLUORITE. THE FLUORITE IS PREDOMINANTLY WHITE AND GREEN WITH A SMALL AMOUNT OF BLUE. |
