don mining engineer, and who serves
the Utah Apex and Utah Develop
ment companies i'm Bingham, Utah, in
a consulting capacity, in a report made
recently, estimated that there are at
least 100, 900 tons-and probably twice
that amount-of smelling ore actually
proved, and adds that a most conserva-
tive estimate of the low-grade, or con-
centrating ore actually proved, is 1,000,-
900 tons. In his latest sampling of the
property. which occurred last month,
Mr. Pearse ascertained that the smelt-
ing ore will average from to per cent
copper. while the concentrating ore will
average from 2 to per cent copper. 1t
will be seen, therefore, from Mr..
Pearse's figuring-and he has the repu-
tation of being very eonservative-that
taking his lowest estimate of the smeit-
ing ore. 100000 tons: and say it aver
ages 6 per cent copper.
Worth Millions.
That means 12,OOO,OOO pounds of met
al, which, on a 2O-cent copper market,
would make it worth 81, 500, 900. Placing
the average of the 1,000.000 tons of con-
centrating ore at per cent, the result
is 60.000,000 pounds of copper, worth
ST.. 900 0GO on 20-cent FER pound basis

After going into the matter of ton
mage and values, the engineer adds:
Il have every reason to believe that
the tonnage stated will be systema teal

Treated CheapIy.
The ores of the Nevada-DougIas mine
being neutral, they can be economical
! ly treated by smelling Ores going 4
per cent copper or better will go direct
| from the mine to the furnaces, while
everything below 4 per cent copper is
claSSed as concentrating ore and must
| first undergo the process of milling. No
| decision has been reached as yet as to
what method will be employed for the
! treatment Of this lOw-grade ORE. but

whether il VIII be by mechanical or
/ electrical concentration or by lixivia-
ton.
Gets Better.
The Nevada-Douglas ore deposits re-
semble in many respects those char
acteristic of some of the big copper
/ producers of Arizona, and striking
| feature about them is the amount of
/ carbonate ores. in which. instead of be
/ ing merely superficial, has been found
TO exist to a depth of LOO feet in an
adjoining property and to $50 feet
depth in the Nevada-DOuglas ground
proper, with no indication of the de-
posits giving out at that depth or the
value of the ore diminishing. Another
feature. The ore s unusually homo
| geneous: for, on breaking a piece of

Systematic Work.
The company has carried on con-
| tinuous campaign of development fO1
the past six months. and contemplate
operating in the future upon very
I broad scale. orders have been placed
for extensive mine equipment which
will be installed soon after the begin
ming of the new year 1907. A railroad
to the mine will no doubt be construct
ed next year. by which time plans fol
the installation of treatment facllltie:
will have been matured.
Last year Mr.. Miller. the locator Of
the ground, shipped 1,500 tons Of ore
from the Douglas mine which averaged
better than 13 per cent copper. 1t j:
