Comments
Comment (Location): NW 1/4 , BETWEEN RUBICON GULCH AND COLE CREEK
Comment (Production): ITEM 8 : YEARS ARE 1885 - 1888 AND 1891 { LARGEST PRODUCER OF PB-AG-AU IN THE CARBONATE DISTRICT
Comment (Deposit): IRON HILL VERTICAL
Comment (Workings): OLD MAPS SHOW ABOUT 6000 FEET OF LATERAL WORKINGS ON 5 LEVELS, THE DEEPEST OF WHICH IS AT 300 FEET. AN EXPLORATION DRIFT ON THE 300-FOOT LEVEL EXTENDS TO THE BOTTOM OF THE NEW TITANIC SHAFT 450 FEET TO THE WEST. A DRAINAGE TUNNEL 1300 FEET LONG EXTENDS S. 10 DEG W. FROM THE 300-FOOT LEVEL AND COMES OUT IN A GULCH TRIBUTARY TO SQUAW CREEK. NEAR THE SOUTH END OF THE CLAIM ARE THE SHALLOW HOME RUN AND BUNTZ SHAFTS.
Comment (Geology): ARGENTIFEROUS LEAD MINERALS ASSOCIATED WITH PORPHYRY INTRUSIONS AND SOFT FERRUGINOUS GOUGE CARRYING AU AND AG VALUES FILLS MAIN FISSURE. ONE POCKET OF 4-5 TONS OF VANADINITE.
