few days. he says:
And IT is not only the ores Of tn,

custom ores--is so located geographic

one OF the biggest undeveloped ore

Virginia city. silver city, Bodie, Au-

say nothing OF Goldficld and Tonopah-

son Valley Mines company smelter at
wabuska.
But as said before. there is enough
ore Of commercial grade developed liz
busy for years.
Further, there is now on the dumps,
or blocked out ready for economical
stopping. enough ore above the No. 4
tunnel In the Mason Valley mine
owned by the same people who are
building the smelter-to furnish the
latter 500 tons a day for at least eight
years. And this ore is OF a grade that
will pay handsomely. even at the pres
ent low price of copper.
There is no doubt about the state

build the smelter they had the ore re-
serves carefully sampled and measured
up. The process OF treatment was de-
cded upon after exhaustive tests and
the cost approximately determined. The
cost of mining and development was
figured out and the cost of transporting
the ore on the railroad to Wabuska Is
definitely known.
at is true the experts fisures-on
which IL was decided To build the
snelter-have been modified, but only
where ore reserves have been added
TO. costs reduced and profits increased.
EXPERT FIGURES.
For instance. the experts figured on
n certain tonnage Of a certain aver
ase grade OF ore above the lowest level
In the mine at the time they exam
ined IL. Their figures were correct as
far as could be demonstrated then.
but the pitch and rake of the ore
shoots are very erratic, and I'm open
ing up the Slopes. Supt. Welsh has
demonstrated that there are thousands
upon thousands OF tons more ore In
the upper workings than the experts
figured on.
''As an illustrations on the third
level cross-cut was run into good
ore shoot. At regular Intervals be-
yond, other cross-cuts were run In the

mercial grade was found. Naturally
IL was figured that the ore shoot ex-
tended only short distance beyond
the first cross-cut, and that no pay
ore was above that level in that part
of the mine. But in opening up
stope at the first oross-cut IL was
found that the ore shoot waS 'wsvy'
at this point. and actually extended
over and beyond the last cross-cuts.
all tho latter being under the ore body
but a few feet In this one stope there
are thousands OF tons of ore more than
the experts included In their figures
and the grade OF ore averages much
better than where first opened.
"The cost OF mining in the Mason
valley mine will not exceed one dollar
per ton-that means the complete cost
OF mining. including development
work. II win do mining mans heart

the economical stopping Of the ore.
Parenthetically, Il may be remarked
that low wages play no part In this
eoonomy-good wages are paid TO good
men and good work secured.
LITTLE TIMBER USED.
There is scarcely stick of tim

will quickly realize what a saving in
cost that means. Then again, In stop

is left in the Slope as Is taken out.
This all tends to economy and leaves

ready to shoot into the cars almost at
a moments notice.
Here Is another thing that sounds
good: The ore at the lowest workings
is the best i'm the Mason Valley mines.

stone that can he found anywhere in
any other copper mine. Do you get
that? 1t sounds pretty big, but you can

I'm tunnel No. 4--about 500 feet
from the surface-the mineral zone Is
about 500 feet wide and diamond drills
will thoroughly prospect the ore
bodies below with the object of de-
termining just where the main work
ing shaft will be sunk. Everything
will be so arranged that this shaft will
be sunk and the lower ore bodies
opened up without In any way inter-
fering with the production of ore
from the upper levels
Not a word Is said about one ore

that will average II per cent copper.
Not a word about chunks of practical

are exceptionally rich. and the man

would probably refuse him permis-
sion to again go in the mine II he laid
too much stress upon the richest ore"
