DESCRIBES PROPERTIES

George l.. Walker the Boston copper
authority. who visited Utah last month,
has issued a letter which gives exhaust
I've data on the Bingham Consolidated s
five mines in Bingham. Mr.. Walker
estimates that $4,000 tons OF ore is
blocked out.
II personally went through and in
spected the underground workings of
all the company's mines when l was in
Utah last month" says MI Walker,
Il visited its smelter, and endeavOred in
every way possible to form an intelli-
gent opinion Of the value and future
prospect of the enterprise. The charac-
ter and extent of the underground de-
Velopments and the amount of ore in
sight were pleasant surprises, as was
also the splendid showing of lead-silver
ore of good grade. On the other hand,
the grade of the copper ores was found
lower than l had previously believed,
and the failure of the company to pay
dividends seemed TO find an explana-
ton, partly in the relatively low grade
OF its copper ores, ana also in the ire
mendously heavy expenditure which
must have been made in the extensive
development of its several properties.
Discusses Commercial.
1.-The company's Commercial mine has
between 800. 900 and $50, 900 tons of ore
in sight. which probably contains about
2 per cent copper and $3.50 per ton in
gold and silver. The ore is i'm two
bodies. and as ii is mined it carries an
excess of iron, valuable for smelling
The Brooklyn vein is about eight zen
feet wide and Of approximately the
same grade as the Commercial ore de-

ever is larger in silver and smaller in
gold. The Lead mine vein, so called,
has not been opened extensively at the
Mascot tunnel level, but it gives prom
Use of making a very big mine, perhaps
the largest in the Bingham CONSOLIDATE
ed group. The vein at one place is $50
feet wide and carries an average of
perhaps IL per cent copper and six TO
nine ounces of silver and a good excess
of iron. There is also in this property
a lead-silver deposit which at one point
is fifteen feet wide and Of excellent
grade.
The longest continuous ore body in
the mine, and probably one of the long
est in the Bingham camp, is that known
as the Dalton & Lark vein. 1t has been
opened on the tunnel level distance

of this distance the vein averages near

$3.50 in gold to the ton. The other GOO
feet so far opened carries two narrow
veins, one CT copper Sulphide and the
other lead-silver. The latter as rule,

Predicts Big Discoveries.
THE Eagle & Blue Bell mine, locat-
ed at Eureka, in the Tintic mining dis
trict. of the stock of which Bingham
owns a controlling interest, is a large
property on which as yet only a COM
Lartively email amount of development
work has been done. One of its SIX or
eight claims is opened by a tunnel from
which there is a shaft or winze 1000
feet deep, equipped with a hoist, and a
chimney of ore has been followed down
and largely mined out 10 about the
sixth or seventh level. Just about the
tenth level this vein, which has been
and extends south. A little more than
ons-half of this vein or shoot is mined
and TIE remainder is discarded The
ore shipped contains a gross average of
a bout S12 to the ton in silver and gold
with very small values in copper. This
property is splendidly located, and the
extension of exploratory work probably
will reveal other ore shoots of value
The ore of this property are very sill
cious. Some Of them are used by the
Bingham for converter Innings and 9TH
ers are treated by one operation. being
dropped raw in small quantities into
the converters with the matte AS
Bingham matte carries a considerable

ton referred 10 is successful. and at
present thirty tons or more of ore are
smelted in this manner daily.
"As stated previously Bingham Con-
solidated is now smelling from 400 to
425 tons of ore daily from its own mines
and about $50 tons OF custom ores, in
some silver ores from Tonopah.
About 200 tons come from the CONNER
cial. 175 tons come from the Dalton &
Lark group AMI forty tons from the
Eagle & Blue Bell. the amount fluctu-
ating slightly from all these sources. |
