ldCe Oh the CTOSSCut IL SnOulu reach
it's objective within a short time.
When it's purpose shall have been
accomplished the crosscut will have
traversed the entire width of the
Blackboard claim. a distance of 800
feet. in a section of the mine
which has not been thoroughlyex-
Ilored.
TOnopah Extension
The Tonopah Extension Mining
company shipped to the Selby smell
ter at Fan Francisco on Wednes-
day of this week a number of bars
of bullion weighing in the aggre-
gate $4,000 ounces which according
to the estimate placed upon this
and previous shipments, has a val
uation of S6O,S4
Since the earnings of February
were published there has been an
increase of nearly 10 cents per n
in the price of silver and the earn
ings of the Extension will be in
creased to a corresponding extent.
And as it is we'll known that the
Extension company receives one
half cent per ounce extra for It's
bullion over the New York QUOTA
tions the treasury of the company
is benefited to a like degree.
The main vein of the mine, that
is the Murray vein, was first in
spected and from the $50 level down
to the 1910 level on its dip the
extensive development work proved
the continuity of the vein to this
depth and for several hundred feet
along its strike. All the ore in this
section is of very good milling
grade and where extraction has
been carried on for some time a
good idea of the size of the vein
can be grasped by sizing up the
big Slopes, which at some places
are 80 feet wide and over
On the bottom level where the
drifts and crosscuts have blocked
out the vein area, the width has
been demonstrated to be 35 feet
wide. How much deeper the vein
will descend is a matter of con
lecture; but the fact that 1t has
not only maintained but greatly
increased in strength as it was de.
velored at deeper levels is suffi-
cient indication hal mining opera
tions will be conducted at still
greater depths than the present bot
tom workings.
On he 1850 level the North Mer-
ger and the O. K. veins were also
examined. Enormous tonnages have
been proved up in these veins, which
have consistently maintained their
splendid values, while in the o. x.
vein it is stated that ore of ex-
~ceptionally high grade is contain
ed. The Slopes on these two veins
al this level have proved a con-
sistent width OF ten feet of vein
and in the case of the North Mer-
ger vein this width is also shown
on the level above. but the o. X.
vein is not so wide on the 1860
level as it has been shown to be on
the level below.
Halifax TOnopah
The connection between the Hal
flax and the Buckeye crosscuts was
made on Friday and the opening is
now of full drift size. Immediate
ly upon the completion of the con-
nection. there was a decided drop
in the temperature of the workings,
and since the first big drop there
has been a more gradual decline
in the temperature. This gradual
decline will undoubtedly continue
for some time as the heated rock
is cooled by the passing air.
The raise from the 1900 level
also holed through last week into
the bottom of the Wine. The last
portion of the raise work was only
a small hole and was done purpose
ly in this name in order to make
the lest footage upward to the con-
nect'on, as the temperature in the
raise was almost unbearable. Now
that air is circulating through the
workings this raise will immediate
ly be enlarged to full three-com-
partment size to conform to the
size of the Wine with chutes for
ore and waste and q manway.
1t is planned to move all the
ore Fellow the 1900 level, which was
blocked out through "a of the
Wine and the 1900 intermediate
level workings, to the shaft on the
400 level.
West End Con.
The West End Consolidated Min
ing company on April IS shipped to
the smelter a lot of 40 bars of bull
lion weighing 67,S53 ounces. At
the price quoted for silver a fair
estimate to place upon the bullion
would be at least Is cents per
ounce; on such basis the shipment
