Comments

Comment (Commodity): COMPLEX ORE REQUIRES CONCENTRATION BY FLOAT TO YIELDMARKETABLE COPPER, LEAD, AND ZINC PRODUCTS.

Comment (Deposit): THE PROPERTY HAS PRODUCED FROM AN OPEN PIT OPERATION DURING 1975. UNDERGROUND WORKINGS ARE REPORTED TO BE REOPENED DURING 1976 - 1977. VEIN BANDS AVERAGE 2-5 FT IN WIDTH. THE INTERVALS MAY RUN UP TO 10 FT, QUARTZ CORE IN PEGMATITE

Comment (Workings): MINE OPENINGS ON THE CRYSTAL AND ADJACENT CLAIMS INCLUDE 2 SHAFTS AND ASSOCIATED LEVELS ON THE ST. LAWRENCE CLAIM; SEVERAL SHALLOW SHAFTS AND PITS ON THE JACK FRACTION BETWEEN THE ST. LAWRENCE AND CRYSTAL CLAIMS, AN UPPER ADIT, A LOWER ADIT AND APPENDED DRIFT, SEVERAL OLD SHAFTS ON THE CRYSTAL, AND AN ADIT ON THE SPARKLING WATER CLAIM AT THE EAST END OF THE MINERLIZED ZONE.

Comment (Geology): THE ZONE OF OXIDATION EXTENDS FROM SURFACE TO DEPTHS OF 25 TO 175 : ONE SHOOT MINED TO A DEPTH OF 400 FT.

Comment (Location): THREE ADITS - LOCATION TAKEN ON ABANDONED BUILDINGS BETWEEN NORTHERN TWO ADITS

Comment (Production): SIGNIFICANT PRODUCTION SINCE 1968 1911, 1913, 1914 PRODUCTION INCLUDED WITH COMET MINE.
