At the Inspiration mine the sink

churn drill work for over year has
Indicated that s2,OOO.0CO tons IL no ex-

ore contained In the great mineralized
schist area which extends I'm an east

property Meanwhile the churn drill
work goes on steadily setting the
boundaries Of the ore farther and far

says "a report from ARIZONA.
Today the churu drill charts and assay
maps taken In connection with the
underground works FIX the length
OF the proven ore body at approx
matelY 3,lN0 feet and It's maximum
width at 500 feet. The vertical extent
OF the ore varies widely. on the edges
Of the ore body the thickness is in some
places not over 1j feet. while along

At the Joe Bush shaft five drifts are
being driven on the 40O-foot level and
on the tunnel level is7 feet above the
fourth, work Is being done in eight
faces thus making a total Of 10.
Nearly all of these faces are In ore OF
average grade and are proving weekly

fercnt directions So far. drifting has
been extended outward from the
shaft 325 feet north. 625 feet east and
700 feet west The east drift now
being driven on the 400-foot level Is
nearing the Miami boundary
At tho scorpion shaft, located

O. drift is being driven southwark to
connect with the extraction tunnel
being driven to the Joe Bush shaft
from Keystone Gulch. This drift from
the Scorpion Is already $50 feet long.
