Comment (Deposit): DEPTH TO BOTTOM AND MAXIMUM THICKNESS GIVEN AS DIMENSIONS OF MODOC AND LONGFELLOW SEQUENCES IN WHICH ALL DEPOSITS ARE CONTAINED; MAXIMUM LENGTH ESTIMATED FROM SHANNON MINE VERTICAL SECTION (LINDGREN 1905) STRIKE AND DIP GIVEN FOR ONE OF FIVE ORE BODIES (BLACK HAWK ORE BODY); 34 CLAIMS TOTALLING 562 ACRES.

Comment (Commodity): NOT LISTED IN PRODUCTION STATISTICS: ZN, MN, FE.

Comment (Location): RISES 1200 FT ABOVE EAST SIDE OF CHASE CREEK AT METCALF; CLAIMS ARE CONTIGUOUS AND COVER SOUTHERN SLOPES OF SHANNON MOUNTAIN. ; INFO FROM LAND.ST :(1973)

Comment (Development): OPERATORS INCLUDED SHANNON COPPER CO, ARIZONA COPPER CO.

Comment (Workings): DIMENSIONS MEASURED ON UNDERGROUND WORKINGS MAP AND VERTICAL SECTION OF SHANNON MINE (LINDGREN 1905)

Comment (Geology): COPPER ORES FOUND IN GRANITE PORPHYRY AND SEDIMENTARY SERIES BUT RARELY IN GRANITE COUNTRY ROCK; LARGE ORE BODIES USUALLY SEPARATED INDEFINITELY AND IRREGULARLY FROM SURROUNDING ROCKS; REPLACEMENT OF LIMESTONE THROUGH METASOMATIC ACTIVITY MOST EVIDENT IN MODOC LIMESTONE WHERE LARGEST ORE BODY OCCURS. SOME OF THE LIMESTONE HAS BEEN PARTIALLY ALTERED.
