Big Financial Journals Give Much
Space to Western Me-
vada Camp.
PEARSE ON DOUGLAS COPPER.
London Mining Engineer Gives Fig
nrcs to Show Il Il Big
Bonanza.

Financial papers In the east are rap
ialy waking up to the Importance OF
Yeringtop, New as copper camp ana
several Of the leading publications nave
been telling their readers that II IS the
next western copper camp to nave
l,oom. some OF them are even pre-
dieting that II will turn out bigger
mines than Ely and special stress Is
laid ON the fact that the Yerington
ores. as a rule are OF much better grade
than is characteristic of the deposits
of the white Pine county camp; me
result OF developments In the NeVaua
Douglas mine have received spevlaI
mention and this properly IS Deconilhs
quite as well known az NeVsda Noh-
solidated and some other western 0oP-
per mines. A.. .,,
known mining engineer of LONDON
England. who serves all of the COM
pnnIes operated in Bingham under the
management OF Walter G. Orem III q
consulting capacity. declares there IS no
doubt about YeringtOn becoming cop
per district of great magnitude.
Mr. pearse has returned from the
west and interviewed by member OF
the News" staff today, gave out some
interesting information about Nevada
Douglas.
~ have been on the Nevada Douglas
property" said Mr.. Pearse, three
times, and have studied IT carefully IL
is a large copper deposit In the lime
stone and. geologically. very closely re-
sembles some OF the large Arizona de-
III I'm
Nevada Douglas deposit Is the amount
of carbonate ore, which. instead OF be-
ing merely superficial. has already been
found to exist TO a depth Of l,lOo feet,
and this, in connection with other fea-
lures. leaves every reasonable ground
10 believe that the ore bodies VIII go
down.
Another striking feature about the
Nevada Douglas mine lies In the fact
that the ore is remarkably homogen-
ious. That IT, II you break almost any
piece OF ore the values are found to be
well disseminated throughout
"Actlve development work has been
carried on for the past six months ana
in every instance where work has been
performed on an ore body, the cohtin-
lllty has been established; not only nor
fzontalfy, bu In elevation NJ we'll
workings tho continuity has been
proved to over $50 feet"
But what can you say about tom
mage, Mr. Pearse ?" was asked
well. win say this replied the
engineer. since making the recent
examination | am prepared TO state
that there are over 100000 tons of
smelting ore actually proved--and a
very cor,servatlve estimate Of the
amount OF concentrating ore shown up
in the same manner Is 100000 tons.
Undoubtedly this quantity viii be sys-
tematicaily added 10 during the next
year,
Regarding Nevada Douglas ore val
mes" added Mr.. Pearse, IL have recent
vs. sampled the mine very carefully and
ind that the average OF the smelling
ore runs from TO per cent In cop
per; whereas, the low grade ore runs
from TO per cent copper. II Is very
evident, therefore. that we are practice
ally certain of both tonnage and val
ues"
After expressing himself In the fore
going manner, Mr.. Pearse took up the
metalurgical phase OF the situation
and declared that the smelling ore
that carrying per cent copper and
up--can readily be disposed OF by
smelling. Being neutral ore, 1t readi-
~ yields TO treatment by fire. But as
10 the low grade concentrating
ore said; II can't say definite
ly whether we win best be able TO
treat it by mechanical or electrical con-
centration or by lexlvlation. Tests are
being made now To determine this, but
] feel very confident that the enormous
quantity Of low grade ore In the Ne
Vada Douglas mine win be available In
one form or another and form tho
broader basis on which the commercial
end of the enterprise viii rest. The
company has recently placed large
order for equipment and electrical pow
er, and the mine is being handled In
a thoroughN up-to-date manner"
The fact that samuel Newhouse, the
Gusgenheims. Capt. Delamar and other
copper mining cnlobreties NJ more or
less prominence have secured extensive
interests IN this Yerington country. II
can be put down as a safe wager that
there Is going TO be some big things
doing In the Mason Valley district from
this time on,
