VIRGINIA CITY, Aug. 22.-The following
official reports were placed on file here TO-
day;
Coz. CAL. & VIRGINIA 100 leyel-The south
drift has been extended during the week 55 feet,
total length from the shaft station Ole feet. The
connection OF this level with the drift coming
north from the Best 6 Belcher mine Will probably
he made this afternoon. Have continued 10 ex-
tract ore from the various openings on the 1900.
1900 and 1000 levels. 1850 leyel-HaVe con-
tuued TO obtain ore OF fair quality from the drift
west from the Top OF the upraise carried up 50
feet above The southwest drift. Ore OF fair quail
ily has been extracted through the drift run east
from Wine down 73 feet In working up-
waId from thai point. 1850 level-In working out
and upward from the bottom of winZe 2,
sunk from the 1850 level, we continue TO extract
ore OF fail quality. The east drift from No.
Wine, at a point 90 feet down. has been ad-
Varced % feet, total length lib feet, passing
through fair grade ore for the first Is feet and
for the last 10 feet Ii vein pOTphyry, carrying
strelks OF quartz; the east wall has not yet been
reached. There mas been extracted from all
parts OF the mine during the we 1865 62020o0
tons OF ore of which 933 100000 tons were
shipped TO the Morgan mill and 1872 250-2o00
