Extension Mining Company. which en-
brace a total OF 4s4 acres.
All these properties are situated on
the western course of the Tonopah vein
system. and have a total extreme length
north and south across the vein system
of 1900 feet or nearly one and a nalf
miles, and continuous length on the
course of the Mizpah vein system Of 800
feet or over one and half miles through
the ground OF the Tonopah Extension and
Mckane Mining Company's claims All
OF the properties are being actively de-
veloped, the most prominent being the
Tonopah Extension nine. which adjoins
the Blackboard claim Of the Tonopah Min
Ing Company on the west, the MacNa-
mara on the north and the Sandgrass
claim of the Tonopah Mining Company
on the south
This was the first property purchased
oy Mr.. McKane and work was COM
menced in May, 1903 a shaft being start

or the Mizpah vein, which happily proved
correct AT a depth of 30 feet the shaft
entered vein in which IL continued for
% feet, dipping out of the shaft at about
20 feet. This vein, known as No l, has
been explored to a depth of 500 feet and
opened I'D on its western course for 500
feet on the 400-foot level, while the east
ern drift is now within a few feet of the
TonOpah Mining Company's boundary
having proved that it is the extension OF
Mizpah vein, and the sinking of the main
shaft has now been resumed.

level a parable. vein was found which

nigh grade shipping ore. and have also
produced specimen ore OF great value. The
total amount of underground work in
this mine amounts to about 1000 feet. ex-

On October 20 the mine commenced
shipments and from that date to April

to 500 tons per week The MANAGEMENT
of this company are not yet at liberty to
give the exact returns for the total
amount of ore shipped. which is graded
to an average value. although some con-
siderable quantity OF very high grade ore
has been marketed. As an instance of this

$500 per ton net.
The mine is sDlendidIy equipped with
a powerful hosting plant a twelve drill

McKANE MINING COMPANY.
The western extension OF this ground
Is owned by the Mckane Mining Com
pany Of Tonopah. having ten patented
claims, which are so located that they
give a length Of 1900 feet on the course
OF the two veins In the Tonopah Exten-
sion mine. The main shaft OF this prop
erty Is located $50 feet west OF the Ton
opah Extension shaft, and has now
reached depth OF 1860 feet, but has not
yet entered the lode porphyry. This Is
a most remarkable instance OF blind
sinking" Inere being no Indications of
mineral on the surface. 1t is probable
that prosecuting for the vein Will COM

Adjoining the Tonopah Extension mine
on the south are three patented claims

Mining Company, where the main shaft
is now down 265 feet A so horsepower
steam hoist has recently been installed at
the mine and the shaft win be pushed
to the 800 level before c-osscutting This

doubtedly be opened up at depth.
Adjoining the Midway mine on the west
are two patented claims and one fraction
owned By the Golden Anchor Mining Com
pany. The shaft on this property reached
depth OF $50 feet. and crosscut north
from this level has recently cut a vein
over twenty feet wide OF milling value.

$40 and $500 per ton. This vein is now
being opened UP and the main shaft is
also being sunk TO the 900-fOot level.
from which point another crosscut Will
be run to the vein.
Ii Is quite impossible to overstate the
value OF this discovery, not only to the
owners of the mine, but also to the Mid
way and Montana Tonopah companies.

general appearance, naturalization and
character OF the ore bears A rernarkabls
resemblance to that of the Macdonald
vein in the Montana mine. but whatever
vein it may be, 1t adds considerably to
the value Of the Midway and Montana

it Increases considerably the known pro-
ductive area OF the camp. Adjoining this
property on the north Is the Bobtau
claim and others comprising the property
OF the
MIDWAY EXTENSION COMPANY.
These claims run north and south and
cover the extension Of any veins running
east and west from Mount eddie which
may be found north of the present work
