ORE DEPOSITS
OF BOSTON CON.
A Boston Brokerage Firm Has
Compiled Interesting Data
About Bingham Mine.
CAPACITY SHOWN.
Estimated Value on Ore Blocked Out
What Can Be Done On High
And Low Copper Markets.

Yesterdays late malls brought an
interesting report on the properties
of the Boston Consolidated Mining
company in Bingham. the data hav-
ing been compiled through the eff
forts OF special representation sent
fere by a well known eastern broker
age firm.
According to the figures submitted
the Boston Consolidated company has
developed 74i.7i6 tons of sulphide
ores. the copper contents of which
are 4l,570.000 pounds. The total tom
rage of this character of ore, in
Guiding probable tonnage amounts to
1,11G,7i6 tons containing 59,46S,00O
pounds of the red metal. The COM
pany Is producing 500 tons OF this ore
day, representing recovery of 49,
coo pounds of copper, or 10000 tons
per year, recovering 10,0S0,000 pounds
of copper. With copper at Is cents a
pound, the annual profit from the sui
phide shipments at the present rate
of output would amount to 730.0S0;
with copper at 90 cents. sl,1S7,640;
and with copper at 25 cents, s1,652,-
400.
OF the porplyry ores, the Boston
Consolidated has available so far
grand total of 5S.5SO,9to tons of ore,
the copper contents of which amount
to 1,S2S.200,100 pounds, The tonnage
of probable porphyry ores amounts to
113.405,0 900 tons, bringing the total M
to 171,9S5,910 tons. The production
OF porphyry ores will amount to 5000
tons per day. containing 62,T2S pounds
of copper; or 1850 900 tons output per
year, from which will be secured o
recovery of 22,bs2,10s pounds of cop
per. From the porphyry ores alone,
at a production of 1900 tons per day,
the company will earn with copper az
Ii cents pound. s1.4SS.240 per year;
with copper at 20 cents. s2,621,1s0;
with copper at 25 cents. s3,T54.OsO.
Including both the sulphide and the
porphyry ores. With an output of $500
tens a day. with copper at Is cents
the company will earn per year, s2,-
ElS,S2O; with copper at 90 cents
pound, S3,SnS.S00; with copper at %
cents. s5,4o6.1S0. The earning per
share under the 15-cent copper will be
$3.50; under 20-cent copper, $500;
and with copper at 25 cents pound
the earning per share will be $3.50
each wear. In explanation OF the
above figures the firm says:
There is one thing which should be
especially noted In regard to these
tables; the estimates of production and
profits given are not merely guesses,
but are based upon actual performance.
In the case of the sulphide ore, the fig
ures are taken from a full years oper-
alton, while In the case of the low
grade porphyry ore. the estimates are
based on the results obtained at the
experimental mill. These estimates
have recently been confirmed by the
actual cost OF treating the ore at the
new 6,O00-ton mill OF the Utah Copper
company. part of which has now been
In commission several months, and
which Is treating porphyry ore exactly
similar to that OF Boston Consolidated,
The total net value of all the ore act
uaily blocked out in both the mines
varies from $50. 1888 600 on 15-cent COP
per to $40, $4,000 on 25-cent copper
1T IN interesting to observe that al
though the management base their es-
Innate of production and earnings from
the sulphide mine on an output of 500
tons daily, there is now. actually being
treated $50 tons per day, and 1t is ex-
pected shortly to increase this to 900.
on account of the gold and silver val
ues in this ore. the cost OF production
is very low, and the earnings from the
treatment of its sulphide are have for
some time been more than sufficient 10
pay all the expenses Of the company,
including the development of the por-
phyry. The mill of 5000 tons capacity
to treat the ores of the latter Is ex-
pected to be completed by the first of
October and to be In full operation by
January. BY November LIST, Boston
Consolidated will have retired all of
Its outstanding bonds and viii also be
absolutely free from indebtedness. so
that its only form of capital obligation
viii be its $4,000 shares of stock.
Provided the railroad can fulfill its
contract OF transporting 5000 tons per
day, by the first of next year Boston
IA ~
the rate of S2.OoOOOO pounds annually,
at cost NJ less than cents pound,
SO that should copper in the meantime
fan to Is cents n pound. the company
would still be able to earn SO per share.
This should give the stock an invest
ment value at all times equal to the
present quotation. while the possibility
of erning as high as S. per share on
a 25-cent copper market would give
the stock a very much larger specula-
tive calue on all rising metal markets."
