General comments

Subject category Comment text
Deposit LEADVILLE LIMESTONE BEDS STRIKE NE AND DIP STEEPLY NW. SILVER FAULT SHOWS THICK BRECCIA OF PORPHYRY, SHALE, LIMESTONE, AND OPEN FISSURES AND WATER COURSES IN LIMESTONE. MOST OF WORKINGS RUN ON CONTACT FAULT. LATER PARALLEL CROSS-FRACTURES AND SLIGHT-DISPLACEMENT FAULTS STRIKE NW, HAVE STEEP SW DIP, AND OFFSET SILVER AND CONTACT FAULTS. EFFECT OF THESE LATER FAULTS ON MINERALIZATION IS UNKNOWN.
