Deposit SEVERAL NORTHEAST STRIKING FRACTURES APPEAR TO HAVE SUPPLIED SOLUTIONS WHICH CAUSED REPLACEMENT-TYPE MINERALIZATION IN CALCAREOUS BEDS NEXT TO FRACTURES. DOMINANT TYPE OF MINERALIZATION IS REPLACEMENT-TYPE. THIS AREA IS SOMEWHAT UNIQUE IN THAT THE DOMINANT ORES ARE CU AND AU AND ALTERATION AT THE SURFACE CONSISTS OF SILICIFIED, IRON-STAINED BRECCIAS.
Deposit Discovery Year: 1870'S
