THE MASON VALLEY mine
Some Interesting Facts and Figures Concerning
This Magnificent Property and Reasons for
Large Profits Certain to be Realized
by Stockholders

During this exciting time, when the
financial as well as the speculative world
are breathlessly waiting the announce
ment of great merger, sure and certain
to bring about Is cent copper, the unde-
veoped sections and prospective pro-
ducers are attracting nearly as much
attention as the reliable old dividend
payers. The merger, in order to con-
troll the price of copper and keep it at
anything like the figure desired is tax
ing into consideration and keeping a
sharp lookout on the new fields from
which will come new supply.
In its search for new deposits, the
Yerington district. for which several
smelters are being planned and rail-
road building through it, will be the
first to attract its attention.
The mineralized zone is immense and
the presence of the red metal in COM
mercial quantities is proven beyond a
doubt. Several properties have sunk to
great depth and exposed enormous bod
les of rich copper ore, but the Mason
Valley company is the one concern
which has progressed sufficiently with
extensive and systematized exploration
to understand perfectly the peculiar
characteristics of the copper deposits
and remove all doubt as to the perman-
ency and richness of the camp.
The Mason Valley company is incor-
porated for / 900, 900 shares of the par
value of 81 each. Work has been s,ead-
lily going on for the past four years with
an average force OF 40 men, and there
has been expended in development and
equipment nearly $500, 600. Up to the
FIRST of the year there has been done a
fraction more than FIVE miles of under
ground work, and in performing it four
enormous columns of high grade ore
have been found to exist in huge bodies
of lime desirable for fux. carving an
excess of iron and one and one-half per
,ent i'll copper. Two of these columns
have only been exposed and sampled
where the main drift on each level
passes through, but give every indica-
ion of enormous tonnage and high
values, another is partially blocked out
md roughly estimated to contain above
he lowest tunnel level 700, 600 tons OF
per cent copper ore, the other is
body of ore 490 feet high. 270 feet long
md IS feet wide, blocked out from the
owest tunnel level to the surface and
thoroughly sampled. 1t contains about
500, 600 tons of ore averaging l-2 per
,ert in the red metal and trace in gold
and silver The work done includes
about 1900 feet OF drifting, 2600 feet of
,rosscuts, $50 feet of diagonal cross-cuts
On each OF four levels; 5000 feet of tun-
nels, entrances to the mines and not in
pre-, 200 feet of wines. 1000 feet of up
raises and about 1000 feet of stopping and
out. The copper bearing ledge
averages in width from IS to 800 feet.
In the drift Just south of No. 3 tun-
mel twenty chutes are being installed
through which can pass 450,0o of
this 900, 900 tons of l-2 per cent ore.
Several of these chutes have already
been completed and just above the cell
ing of the drift sufficient ore has been
mined and placed on the dump to leave
a chamber 270 feet long, As feet wide
and 10 feet high, the floor of which puts
one in mind of the automatic dumping
