tonnages at this great Bingham mine:

feel somewhat skeptiea about helicv-
ing the correctness OF them But three
OF the tunnels being run in the mon
aonlte porphyry zone according to
statement made by Manager Louis S.
Gates o few DAYS ago. win expose all
OF 100000 tons of ore.
This almost seems incredible. vet the
manager is IN position to back no this
assertion By actual measurements I'm a
zone known to be 1900 feet long coo
feet deep aud 500 feet Wide.
The Boston consol dated contains. as
the mining public is quite well aware,
two mines within itself II has ono

while in the porphyrlcs. which have
made the Utah Copper so well known
IN the mining world. Is another. OF stu
pendous proDortions--one that win
take considerably more than an ordn-
airy lifetime to exhaust.
Shipment of sulphldc Orc.
From tho sulphide mine. shipments
have been made during the past sew
eral months at the rate of 300 tons a
day and preparations are under way
TO supply the shelters with $50 tons. or
more beginning on May / next
The development campaign that has
been carried on during the past three
months has resulted In some startling
developments In this portion of the
mine. Three large and new ore bodies
have been opened I'm new territory.
One OF these bodies. as far as devel-
oped. shows an average Of per cent
copper and It has been opened TO the
extent of ito feet IN length so feet in
width. with a raise run for i5 feet No
stopping has been done from this body
as yet.
Peabody Tunnels Importance.
On the Peabody tunnel level, the
management claims, has been devel-
oped the largest single sulphide ore
body In the camp of Bingham This
body, which has been developed TO the
length OF go feet, shows q width OF 1870
feet and has been raised on for so feet
In preparation for the greater pro-
duction to be undertaken during the
coming wear. the mine equipment is be-
Ing doubled and in three or four
months the probabilities are that new
compressor plant will be installed. The
ore bin capacity at the mine IS also
being doubled.
lngcrsoli and Phoenix Veins.
A long cross-cut is now being run to
connect the Peabody level with two
other isolated. but important. veins
the Ingersol and Phoenix The OPEN
Ing of these ore bodies will double the
available tonnage for mining. II is ex-
pected that the cross-cut will be COM
pleted within the next three or four
months. The last named bodies VIII

Wealth of the Porphyries
The surprising success of the Utah
Copper company in the mining OF the
p0rphyry ores Of the camp made IL APP
parent that III this zone the Boston
Consolidated had a valuable asset. So
the development of this portion of the
mountain within Boston Con. territory
was commenced In March last through
the driving OF what is known as the
Tech tunnel The result OF this work
proved to be so encouraging that IL
others were started and. since then.
one and Il half miles of underground
workings have been started. Three of
these new tunnels--the Ben Hur Nos.
and 2, and the Metropolitan, have
shown phenomenal values in copper.
with which is associated quite sur
prisng showing of gold. The daily as
says taken during the past three
months on ore from these adits have
averaged 3 per cent copper; while from
the Metropolitan. during the last three
weeks of November, copper averages
have run from 3 to ) per cent The
most encouraging part of the develop
ment of the porphyres so far shows
that the best values are near the top
OF the mountain, which gives from GOO
TO 700 feet elevation for mining above
the Greek level.
VIII Use Steam Shovels,
II Is In this vicinity that mining by
the use OF steam shovcs win come in
TO play and the management is now
laying out some work for them. Min

placed an order for three cotton shoV-
els one of them will be delivered soon
after the first Of the year. while the
other two are to be delivered by Aug l.

these machines that II railway facili-
ties were available one Of the shovels

ores as the Bingham porphyries per

loading and dumping of a shovelful Of

of the management OF the company 10

mountain, one for mining purposes,
while the third will be kept In reserve
