CONSERVATIVE REPORT OF ]. A.
SNEDAKER ON THE PROPERTIES.
PREDICTS A LIFE OF FIFTY
YEARS FOR THE MINES
Rec the Treatment of
Ores by a Smelter.

The following Is summary OF the re-
port recently made upon the properties
OF the Mckinley Mining & Smeting Co.
OF this place by James Angus Snedaker
mem ber of the American Institute Min
ing Engineers, and American Associa-
tion Advancement OF Science, who ia
well known here aud has large interests
in the Giroux Consolidated Mines at
Pilot Knob. Being thoroughly familiar
with the district. Mr.. Snedaker knows
whereof he speaks:
I'm summing up the merits of your
property the vital facts will be entered
into simply and concisely
First, the vein as covered by the
Saxton Group and Jupiter Group, cQv-
ers $50 acres of ground and the out.
crop of this great vein 5.200 feet in
length, o. 80 feet less than one mile .
Throughout the entire length OF
| this territory, there Is exposed on the
surface mineral bearing vein from POO
| feet Ia width TO an extreme width OF
4I2 feet between walls, having a lime
stone hanging wall and a foot wall
| (Which Is heavily mineralized) it posi-
| bly being hornhlendic andesite and
| quartz porphyry, which is the ore pre-.
ducer and is noted throughout the pre-
cious metal mines OF the world as rock
| that in connection with limestone in
particular has created some of the
| greatest ore bodies In existence.
"The geological conditions existing
| upon this property are such that tax

| great mines of Mexico, Arizona, Utah,
| as well as the State of Nevada aud also
| the Lead vile district OF Colorado, where
| the same conditions occur, have formed
| the wonderful ore bodies that exist IN
| those camps and countries, exist upon
| this property and the ore occurrences
| are similar ia their nature.
"From the ores that have been ex-
| tracted from the surface, containing the
| precious metals, the quantities OF the
| same aud the mineral conditions and
| the enormous Masses and cliffs OF min
eral as exposed particularly upon the
| Jupiter group, there is no other reason

what when the development work has
| been so far ad vanced there. this prop.
erty will be one OF the great producers
| of this whole region, or in other words,
| when the State OF Nevada gives TO the
| people Il mine, it is generally one OF the
| greatest.
''In your property, particularly the
Saxton shaft development there is some
% feet of ore in width in the PIP foot
level and the intermediate level between
the 120 and 2l2.
| "Taking the amount of ore that is In
sight In these two different levels, esti-
mating that there Is, at least, 25 feet
thick OF ore that will average 8 to l0
dollars in gold that Is favorable to
treatment by the cyanide process, there
Is enough ore in sight tn justify the op.
Grafton of teaching plant upon this
particular ore, but would advise your
Company not to extract these ores and
treat them by that process at present,
out TO hold these ore reserves until
such time that the copper sulphlde
ores in your property are sufficiently
developed; then the Company can utll.
ize the ores lying uearer the surface in
their smelling plant, as that will be the
future process OF treating all the ores oil
your Company. | would not advise
the erection of smelling plant until
further development.
'As to the probable future of these
mines and the life OF them, there is nG
reason that | can see, but what these
mines should last, at least, for nifty
years and they should he profitable fCr
that length of time, as they are contact
assures of such great size and strengths
and as the lime stone and other sedi'
mentary rocks which form the hanging
wall OF this vein are in the neighbor
hood of 4, 900 feet thick. as near as car
be ascertaiued. and your vein should
extend In depth, at least, that tar and
be profitable.
"You have an ore shoot several hun
dred feet long upon the Saxton ground
aud the ore exposures upon the Jupiter
group is nearly 2, 900 feet long; and tn,
vein, which varying in width of 200 tt
over 400 feet between walls, 1t is simply
question of proper development being
carried out on a scale commensurate tC
the size OF the vein TO make these mine:
producers of, at least, 1000 tons OF orr
per day, and to make the property VI
, to that point OF its development, vii
require more time. Then your Com
pany can safely figure upon such a siz,
reduction plant, namely a 1,000-toI
plant.
I'm my judgment your Company ha
without doubt one of the future grea
mines OF the State of Nevada.
Respectfully submitted,
JAMES ANGUS SNEDAKER.
