| Deposit | DEPOSIT CONSISTS OF PB- AND AG-BEARING JASPEROID PODS REPLACING LIMESTONE ALONG HIGH-ANGLE FAULTS. INDIVIDUAL PODS RANGE IN SIZE FROM 5 TO 30 FEET IN LENGTH AND 2 TO 10 FEET IN WIDTH. TEXTURES REVEAL SEVERAL PEROIDS OF ALTERATION AND BRECCIATION. LARGEST JASPERIODS OCCUR AT THE INTERSECTIONS BETWEEN SEVERAL MINOR NORTH-SOUTH-STRIKING FAULTS AND A PROMINENT EAST-WEST-STRIKING FAULT. DOMINANT SULFIDES ARE PYRITE AND GALENA. GEOCHEMICAL ANALYSES SHOW A CONSISTENT ENRICHMENT IN AU, ZN, AND MO IN ADDITION TO PB AND AG. PROSPECT LIES NEAR THE MARGIN OF A 36.2 +/- 1.4 M.Y. OLD GRANODIORITE STOCK. |
