Very little change has been
made in the surface equipment of
your property during the past fis-
cal year.
Installation of Laidlaw-Dunn
Gordon company compressor of $50
cubic feet free air capacity was
completed. This compressor is
fitted on both air cylinders with
Rix automatic unloading device.
"A 500 horse power motor was
placed on the Mizpah hoist, and the
$50 horse power motor originally
with that hoist was transferred to
the Silver Top hoist.
"A small building was erected
for the drill sharpener, in order to
separate this class of work from the
general blacksmithing, and to pro
vide each shop with needed room.
1.-TWO sinking pumps were addet
to the pumping equipment durin,
the past year. A Smith-Vaile 20'
gallon and a Cameron 100 gallol
capacity. This purchase became ne
cessary as the flow of water en-
countered in the Mizpah shaft in
creased at times to IS gallons pc
minute, and exceeded the capacit
of the SO gallon Smith-Vaile frs
purchased, reserve sinking pun
being a necessity in such opera
tiCns.
Practically no change has bee
made in the mining methods dul
ing the year. The blasting Gre
method is still in effect, and bring
good results as to costs.
During the year 231, 1856 wet tor
of ore and waste were hoisted frOl
the Mizpah, Silver Top and Re
Plume shafts, of which 166,07S dr.
tons of ore, of an average value {
5000 per ton, were shipped
the Desert Power and Mill compan,
5,997 dry tons of low grade OF
placed near the railway spurs on tt
surface, 53,423 dry tons of wast
rock sent to the surface dump
Waste rock from development VOL
was also used to fill abandone
,topes.
1.-THE average mining costs fl
the year were:
Per dry ton shipped to the mi
$4.172.
Per dry ton ore and waste hois
ed. $2.9S7.
Per dry ton ore shipped to mi
including cost of shaft sinking, co
drilling and extra excavations, s.
$50.
These costs, taken per dry ton
ore shipped to the mill are 80
cents lower as to direct costs, al
434 cents lower as to total co
excluding extraordinary develo
ment, were reduced 23.1 cents. Tn
there was not a proportionate
duetion is due to the fact tn
there were 1885 feet more sh'
sinking and 1104 feet more &C
drilling done this fiscal year tn
the previous year, and that be
classes of work performed unt
difficult and expensive conditions
to water flow and rock formati'
II is noted that 1913 feet mt
development was done this ifs
year than during the previous "
and at a reduction in the total c
of ss.sSi.0s. The increased TO
age in wines and raises, a class
development that Is more expens
than drifts and crosscuts.
