| Deposit | DEPOSIT LIES IN SMALL NW-TRENDING FAULT BLOCK BOUNDED ON NE BY BONNYBELL FAULT, ON SW BY CHLORIDE FAULT, AND ON NW BY NE-TRENDING SILVER FAULT AND CUT BY MANY SMALL INTERNAL FAULTS. BELDEN SHALE AND PORPHYRY DIRECTLY OVERLIE LOWER LEADVILLE DOLOMITE MEMBER. PORPHYRY OCCURS AS LARGE CROSS-CUTTING DIKE AND SMALL INTERBEDDED SHEETS IN DOLOMITE, MARBLIZING THE DOLOMITE AROUND CONTACTS; MINE IS ONLY PLACE IN DISTRICT WHERE PORPHYRY WAS SEEN TO CUT BEDS OLDER THAN BELDEN. OXIDIZED ORE FOUND IN IRREGULAR SHOOTS PARALLEL WITH MAIN FAULTS AND HAVING NW TRENDS, DIPPING STEEPLY SW. OCCURRENCE IS SIGNIFICANT IN DISTRICT AS IT IS ONLY PLACE WHERE ALL OF HOST ROCK WAS TRANSFORMED INTO LOW-GRADE ORE. |
