| Deposit | ORE IS PRESENT AS VEIN, STOCKWORK, AND REPLACEMENT OCCURRENCES. HOST QUARTZITE IS SILICIFIED AND CONTAINS LOCAL PATCHES OF FINE-GRAINED, DISSEMINATED SULFIDE REPLACEMENT. HOST IS ALSO CUT BY NUMEROUS VEINS AND STOCKWORK VEINLETS OF OF QUARTZ. MOST VEIN QUARTZ IS FINE GRAINED, BUT LOCAL COARSE COCKSCOMB QUARTZ IS PRESENT. MOST ORE APPEARS TO BE THE OXIDE REMAINS OF PRIMARY SULFIDES. PRIMARY SULFIDES ARE TETRAHEDRITE-TENNANTITE, GALENA, CHALCOPYRITE, AND PYRITE. |
