Deposit Discovery Year: EARLY 1920'S
Deposit A LARGE DIKELIKE VEIN OF JASPEROID OCCUPIES THE EAST CAMP FAULT ZONE, WHICH STRIKES N 60 W AND DIPS NEAR VERTICAL. FLUORSPAR VEINS PARALLEL THE OUTSIDE WALLS AND ALSO WIND THROUGH THE JASPEROID. FLUORSPAR CROPS OUT IRREGULARLY IN A PERSISTENT VEIN PARALLEL TO THE JASPEROID DIKE FOR A DISTANCE OF 2500 FT. THE WIDTH OF THE VEIN RANGES FROM 12 TO 15 FT. THE VEIN MATERIAL IS COMPOSED OF FINE TO MEDIUM GRAINED QUARTZ, JASPEROID BRECCIA, FINE-GRAINED TO COARSE-GRAINED FLUORITE, AND MINOR AMOUNTS OF ARGENTITE, GOLD, HEMATITE, LIMONITE, AND MN-OXIDES. THE FLUORITE IS CLEAR, WHITE AND GREEN, AND HAS SOME HEMATITE STAINING.
