been found 100 feet south of the
Poloverda-Velvet side line in a raise
from the 932-foot level, and quite
a large tonnage will be mined dur
ing the coming year.
Crosscuts are progressing on the
932-foot level in 2 southerly direc-
ton, with the view of prospecting
the southwestern portion of this
claim.
Velvet Claim-In this claim A.
$40 feet of development work was
performed, which together with the
slopes, produced 9,O49 wet tons OF
shipping ore averaging $74.14 per
ton, and 2,545.7 wet tons Of milling
ore averaging $11.14 per ton, or Z
total value Of $~699,375.70, mine
sample.
A new shale-latite ore body va
found near the PolOverda-Velvet
side line on the SS0-foot level. The
upward extension has been proven
for 100 feet and the downward eX-
tension is exposed in the raise from
the 1017-foot level. Drifts On in
eimediate levels show this ore body
to le continuous between these two
points. 1t is practically assured that
the ore body will produce a consid-
cradle tonnage during the coming
year..
The shale ore body has been
proven from the 952-foot level 10
the 1O17-foOt level. 1t has been
stopped between the 964-foot level
and the 952-foot level. Stopping is
now in progress between the 975
foot level and the 964-foot level
Both the contact vein and the sha!9
vein lie very flat, having an aver
age dip of 81 degrees from the hO-
%riZontal. This fact explains tha
short vertical distance between lev
els.
1t was decided during the year TO
enlarge the Velvet shaft to three
compartments and sink it to 1000 :
foot level. This will facilitate pros
p~ecting and developing in depth the
nOrtherly section of the Velvet claim
and will allow of greater develop
easterly portions of the Poloverda
and Velvet claims. This shaft, now
designated at shaft No. 2, is located
$50 feet north, so degrees east from
the PolOverda shaft. Enlarging and
retimbering started May 23, and
continued from the collar to the
2S0-fOot depth, at which point the
bottom was found. Sinking was then
started and on June 80 a depth of
312 feet had been attained. 1t is ,s-
timated, barring unforeseen delays,
that the 10O0-foot level will be
reached Jan, 1, 1916.
Mill Operations-Your leased mill
at Bonnie Glare, New, was shut down
field Consolidated Milling and
Transportation company's mill start
ed operations on your ore June 6.
1914, and continued until Sept. 10,
1914. On account of a change in
the character of our low grade ores.
which now only carries q small per-
centage of copper, they are not now
susceptible to the treatment used
in the Consolidated mill.
Mill Tailings-Your mill tailings
have been impOunded at the Bonnie
Glare mill since the starting of OPP
Grafton. These tailings represent an
asset, and experiments have been
conducted during the II months
with a view to re~treating them AZ
a profit, but so far without success
However. experimenting will con-
tinue in the future.
Milling Ore-Bodies of low grade
ore are exposed in various parts of
the mine. We are now mining the
ore as it comes, so long as each ore
body mined yields a margin of prof
it, The workings expose large
quantities of mill ore, the gross CON
tents of which per ton are below our
present working and shipping costs
per ton. Experiments have been
made during the past yea for the
purpose of finding some milling
process by which this low grade ma
terial can be made a valuable asset,
but thus far without success. How
ever, the available tonnage is suf-
~ficiently large to continue expert
menting along these lines.
Ore Reserves-It has not been
considered advisable in the past 10
attempt an accurate estimate of to-
tai ore reserves, on account of the
irregularity in both shape and value
and other peculiar features of the
ore bodies; however the present ex-
