| Deposit | VEINS (ATTITUDE ABOVE) LIE IN FISSURED ZONE 60 TO 70 FT WIDE. PRINCIPAL VEINS, EAGLE (WEST) AND EAST, VARY FROM 2.5 TO 17 FT WIDE, AVERAGING 4 TO 5 FT. AT NORTH END MINE, EAGLE AND EAST VEINS INTERSECT, PITCHING SOUTH. VEIN WIDENS AT DEPTH. INTERMEDIATE VEIN PINCHES AND SWELLS AND IS RARELY MORE THAN 6 INCHES WIDE. NUMEROUS FEEDERS AND FRACTURES BRANCH FROM MAIN VEINS AND LIE MOSTLY IN HANGING WALL. HIGH-GRADE AG ORES OCCUR AS LENSES AND CHIMNEYLIKE SHOOTS IN LATE FISSURES IN AND ALONG EARLIER LOW-GRADE VEIN MATERIAL. HIGH-GRADE AG ALSO OCCURS IN FOOTWALL VEINLETS ON LOWER MINE LEVELS. ORES COMPLETELY OXIDIZED IN UPPER 100 FT, AND OXIDATION EXTENDS 250 TO 300 FT. EAGLE IS ONLY MINE IN BONANZA DISTRICT TO HAVE PRODUCED SIGNIFICANTLY FROM FLUORITE-RHODOCHROSITE VEIN. |
