AOANOA Al |
The Montana mill treated 1880
of ore during the week with the
usual percentage of extraction. OF
the ore 646 tons came from the Mon
property and 3S4 tons from the
MacNamara. The development work
for the week totaled 2O4 feet.
396-foot level-The east drift on
the Triangle vein along the fault,
advanced twenty-three feet and aver
ages three feet of good milling ore
over the distance traversed. Stop
ing was continued on the Triangle
vein during the week, where most
of the work was confined to the west
end of the stope as the work of fill
ing in the central portion continues.
The vein at the west end averages
about two feet in width of milling
ore and the last work done shows
there is more ore coming in on the
footwall side where it is separated
from the main ledge by about two
feet of waste. The raise on the Mac
donald vein has advanced about fif-
teen feet, and is now up seventy
nine feet from the track. The top of
the raise shows three feet of quartz
of a grade too low to work.
462-foot lever-The drift east on
the Martha vein advanced thirteen
feet and the face shows about two
feet of low grade vein stuff. The
west drift on the same vein advanc-
ed twenty-one feet. The face shows
about two feet of fairly good milling
ore where the vein Is cut off by a
fault. The stope on the Martha vein
is being timbered and the work of
cutting out a new stope on the South
vein has been started. Stopping con-
tinues on the Macdonald vein 1000
feet west of the shaft where the vein
averages about four feet in width
and carries good milling ore. The
raise on this vein, about 500 feet
west of the shaft has advanced six
teen feet, where the top shows
stringers of quartz carrying low val,
ues.
515-foot level-The west drift OF
the Macdonald vein has advanced
eleven feet and the vein averages
about three feet of good milling ore
The east drift has been extended
eighteen feet and shows two feet O
milling + in the face. The VIM,
on this vein was sunk twenty-ont
feet during the week and is nov
down thirty-five feet from the level
The bottom shows about two feet o.
milling ore on the hanging wall, but
the greater part of the ore body Ii
on the footwall, it being separated
by a body of waste. C%rosscuttins
will be started later on this ledge tC
determine its exteny.
615-foot level-The crosscut thal
was driven for the purpose of reach.
ing a desired point underneath the
winze from the third level, which
was sunk on the South vein, is il
thirty-three feet and a place is nov
being cut out for a switch. The worl
will be started Immediately to con
meet with the Wine. This raise will
go up on an angle of about SO de
grees. Stopping is continued on tn,
Martha vein about 200 feet east o
the shaft, where the ledge average
about two feet wide and carries al
oxidized iron stained milling ore
~Timbering is being done in the rails
on the new vein encountered nea
the Midway side line and a chute will
soon be put in so the ore can b
stopped out to an advantage. Stopin
is progressing on the Macdonald vel
t in two places underneath this leveI
where the vein averages about fou
feet in width. The slopes on the !
b. X. vein above the level, both cas-
S and west of the c~rosscut, averag
/, about fifteen inches of good grad
!, ore.
{ 765-foot level-Work has bee.
started again in cleaning out tn
sump and retimbering the shaft TO
t the purpose of driving the crosscu
e ahead once more. This crosscut
t now out 1900 feet from the shaft.
