| Deposit | THE BEDS AND THE VEINS AT THE HOPE MINE STRIKE N 10-60 E AND DIP ABOUT 30 NW BUT BOTH ARE VARIABLE. SOME OF THE LARGEST ORE BODIES OCCUR ON THE CREST OF SMALL ANTICLINES OR IN THE SADDLES OF SMALL SYNCLINES. VEINS OCCUR AT SEVERAL HORIZONS AND SOME ARE CONNECTED BY THIN STRINGERS THAT PARALLEL THE W-STRIKING DEEPLY DIPPING VEINS TO THE S. THE MAJOR VEINS ARE DIVIDED INTO TWO GROUPS THAT ARE SEPARATED BY A 400-FT INTERVAL OF BARREN ROCK. |
