ment at the tailings plant. Owing to
the conditions existing at the beginning
of this half year, our available supply Of
ore was practically exhausted, and it
was again necessary to stop the mills. for
a time and push the development work
at every promising point. The mills We're.
therefore. only employed during Is days
of July and discontinued entirely during
the last half OF July, the whole of Aug
ust and September. and half OF October.
The August and September expenses,
with no milling to bear any part of work
ing and development. were respectively
SASS and $l2 795, or AN average expendl
ture of $13.SO0 per month. You will, there
fore, observe that by operating the mill
when any ling ore could be found. this
last mentioned expenditure has been re
duced to an average cost of $500 per
month or a gross saving of $4,000 dur
ing the ha.f-yeay. With this explanation
you viii see how very Inconsistent it
would be to make comparisons with the
tonnage produced. You will, however.
notice a very decided reduction in the
working expenses, principally due to the
work done for Mr.. Cruise. In addition to
our regular output, we have received
from the so stamp mill IS. 10000 produced
from the plates, and have returned to
stores quicksilver to the value OF $4,000.
The plate amalgam was melted with our
mi bullion and was realized upon
through that source
At present 80 stamps of the 60-stamp
mill are employed The supply of ore for
this number of stamps is not in such
shape as to be accurately estimated ev
cry part of the mine furnishing por-
ton. This may continue for several
months but it is impos sible to say how
long this grade of ore may last.
Dam Tailings Plant.
This plant was operated practically
during the entire half year. and 72,51S dry
tons of tailings We're treated during this
period, resulting in profit of 500, 269.26 or
s1.S3 per ton. nearly so per cent Of the
rea ized value of the tailings treated.
The entire cost Of this plant has now
been repaid to capital, as will be seen
from the accounts. Hereafter there Will
be a reduction in the royalty paid for the
use of the process, which will be reflected
in the working expenses during the next
season.
BY comparison with the corresponding
half-year of 1899, it will be seen that the
realized values were about the same for
both years: the working expenses some
What less, and the net profit trifle
more per ton for last lalf-year. This
condition may be accounted for by the
absence Of the redemption charge practi-
cally during the last two months: this is
party offset by the charges for treatment
and transport which are trifle higher.
owing to the change of operations from
Dam No. 4. to Dam No. 5. it being
greater distance to haul the sand from
No. Of thereby increasing the cost of
transport.
Owing to the shortage of water last
winter and early in the spring, we We're
unable to sluice the necessary tonnage
from the upper dams to the Dam; and
were therefore obliged to change our OPP
erations to No. during the working sea-
son. This we did without any loss of
time or treatment.
The Mines. .
The development of the mine consisted
of 2.736 lineal feet of shafts drifts, cross
cuts, up' aises. and wines. at a cost !, Of
s51, 1852 % or $3.50 per ton of ore extracted.
While prosecuting this work we dis
covered and treated 1SO1 tons of ore the
