Subject category Comment text
Deposit CUPRITE IS DISTRIBUTED IN FINE SCALES ON THE JOINTS OF ALTERED CLAY SHALES. AZURITE FORMS LARGE MASSES OF ORE. ORE BODIES OCCUR THROUGH OUT THE LONGFELLOW LIMESTONE. ORES IN THE MANGANESE BLUE MINE OCCUR ON 4 PRINCIPAL HORIZONS: ON THE FIRST HORIZON, ORE FORMS A SOLID SHEET OF HIGH-GRADE AZURITE AND MALACHITE STAINED BY MANGANESE TO THICKNESS OF 10 FT; SECOND HORIZON ORE FORMS THE SAME TO 25 FT THICKNESS; THIRD ORE HORIZON CONTAINS CUPRITE DISSEMINATED IN SHALE; FOURTH ORE HORIZON FORMS THE SAME TO 20 FT THICKNESS.
