lana mill aggregated 9S3 tons. of
which $50 tons came from the Men
Ana workings and 233 tons from the
uocNamara property. The per cen
If extraction was 1914. In the
mine developments work for the week
totaled 22S feet.
S96-foot level-The raise on the
Macdonald vein at a point about 800
feet west of the shaft has advanced
seventeen feet. The vein averages
from three to four feet in width, but
the quantity of the ore is too low
Grade to mill. The stope is begin
ming to show some spots of good ore
and is looking considerable better
since last weeks report. The east
drift on the Triangle vein along the
fault has advanced twenty feet, the
first half OF which is in low grade
oxidized milling ore. The face
shows about two and one-half feet OF
fair grade ore During the week a
considerable amount of ore was
broken from the central part OF the
stope where the vein averages about
five feet in width of a good milling
grade. No further work was done
during the week on either end Of the
sope.
462-Foot Level-The west drift on
the South vein has advanced thirteen
feet. The vein which is Of good mill
ing ore Is of an average width of
eighteen inches. The face of the vein
is cut OFF by a fault which has appar-
eltly thrown it to the north in which
direction they are now prosecuting
The East drift has advanced twenty.
five feet along the fault recently en-
countered. The face shows small
streaks of ore which as a whole i
too low grade to mill. The work o.
cutting out a stope on the Martha
vein is further extended and is nov
about 100 feet long. The vein for
this distance averages about two ant
one-half feet of milling ore. Stop
ing continues on the Macdonald veil
1000 feet west Of the shaft an,
which shows no change.
515-foot leveI-The east and ives
flft on the Martha vein have ad
garced forty feet. The vein in tn
vest drift shows about two feet O
high grade milling ore while the cas-
drift vein is OF a corresponding widt
hut OF low grade. During the wee
tho Workings of this level to reac
the limits OF the ore bodies contir
ued for a length of fifty feet. In
gll aoor will now average owe
twenty feet in width. The VIM
on the South vein twenty feet west {
the shaft was sunk an additions
twelve feet. The vein in the bottol
Is very much mixed and broken an
a small drift has been started mort
to prospect.
565-foot intermediary level
The west drift on the South strea
has advanced twenty-five feet ar
shows good ore. During the week
small afount of good ore was broke
from the slopes on the south bran'
Of the Martha vein. No deyelo
ments are being done on the nor
branch of the vein or this level.
615-foot level-The crosscut sou
Of the shaft advanced thirty-fo
feet with no change in the formati'
and the work has been suspend
temporarily. The raise on the ne
vein encountered near the Midw
line, and about ESQ feet west OF {
shaft, has advanced twelve feet. 7
top shows two streaks which
gether produce about three feet
good grade milling ore. Stopping
being continued on this level on
Martha vein east of the shaft and
the A b X vein east and west of
shaft and in two points below I
level west of the shaft on the Nj
donald vein. These slopes show
change.
