Incredulous smiles are provoked
when the statement is made that the
values in an ore body can be figured
as closely as a bank balance.
Derisive smiles were accorded
Morse when he first called the atten-
ton of people to his electrical tele-
graph. .s.3 az
& Scornful smiles will be given the
man who makes statement Of abso-
lutte fact, but with which the hearer
does not happen to be acquainted.
All Of which only goes to show that
in most people there is a tendency
to incredulity; but facts are stubborn
things, and home men. Just like facts,
are stubborn; some are even worse,
they are stupid, because they will de-
ny or dispute the incontestab1e.
In one OF our advertisements, en-
titled Arithmetic. we undertook to
demonstrate how closely the values In
several OF our large ore bodies could
be figured, and we repeat the demon
stration today, but combining ourselves
to only two Of the nine lode claims
owned by our company.
These two are known as the Whip
perwill and Cornucopia. The former
Is 1900 feet in length. and the latter
800. One is an extension OF the other,
but for all practical purposes, It is
simply one continuous claim 2 900 feet
long.
This 1000 feet takes in just that
much Of an exceedingly strong vein,
which out crops on The sdffaee, and
averages about six feet IN width. This
vein can be traced many thousands
OF feet both east and west 81 our To-
cation, showing conclusively that II 10
true assure, even II we consider
nothing but the surface indications.
This property Is located on the
ridge Of the gulch in which our other
properties are situated. The grade of
this ridge Is less than one loot IL 20
so that for our purposes 1t may be re-.
garded as substantially level.
Our crosscut tunnel was started at
point down in the gulch, and after
being driven 100 feet 1t intersected.
this vein at depth Of 480 feet under
the surface. subsequently q winze or
shaft was sunk an additional 50 feet,
and in the meantime an upraise was
made through the ore body to the
surface.
Levels, or tunnels, were driven on
the course Of the vein, both east and
west, from the main tunnel intersec--
tion, with the result that the ore body
was opened up on three sides, and
found tobe Of the same relatively uni
form width and value, thus rendering
easy the computation Of the number
OF cubic feet In the vein. ss5l
This simple little question In Arith-
metic, which cannot be dignif1ed by
the appelation OF Problem, IS thus ex.
pressed: 2,OOox5s0x6 equals 6.s60. 900.
Dividing this by 13. which is the mum
Der Of cubic fet OF our ore required
TO make ton, we find that the total
weight Of this ore body is 4s9. 231 tons
Now It becomes necessary to get al
4 the value Of that ore. We have never
figured better than SO per ton. al
though we have known from the be
ginning that 1t was from s. 10 8 times
that much. but, accepting The S1t
value, there Is no escape from wha1
the figures tell yon. VIZ: 1850, $40
And this is in one property, opened Il
q depth Of $50 feet onlyl
But, let US got little closer to tho
facts, because they are interesting
from more than one standpoint. This
ore body was opened at this depth Il
the early ninties by the then holding
company. an English syndicate. i
was hoped the ore would be desirable
for free milling purposes. but much tx
the disappointment Of the Nnglish
men, It was discovered that NOT owe
20 per cent Of the values could be re
covered BY the stamp mill. Or amalga
nation process. which at that tim.
was the only one Of consequence.
Maps Of the underground working
show that about $4,000 tons of Till
ore was mined. and therefore, presum
