MONTANA'S Big
MINERAL OUTPUT

uEcdI SlTIutS were nlHuc ny VIC
state of Montana in 1912 in the pro-
duction of gold, silver. copper, lead.
and zinc. according t. V. {. Heikes,
of the United States geological SUR
vey, the value of the output being
placed at SG4. .754 1913. against $46 $780,
2o7 in 1911, al increase Of SIT, ,700,3 1926,
due to the greater production and
higher value OF copper. Most OF this
increase-sl7, 79S ,60s-may be credit
ed to the production Of Silver Bow
county. which includes the Butte dis
trict. The combined production OF
the other counties in Montana was
only S62s in 1912 than in 1911. The
value of the silver, copper and lead
production combined slo, ,524, ,437 more
than in 1911, while the value of the
gold and zinc was S725, Ill less than
in 1911.
The production of gold in 1912 was
valued at $3.625, ,235. against S3,7lO,.
ISL in 1911. Over 36 per cent of the
gold, or 9S, 770.72 ounces was derived
from siliceOus ores; 39,O1O.52 ounces
or 22.2 per cent, from plactrs; and
34.2OO.S3 ounces or 1913 per cent from
copper ores. Tie placer gold pro-
duced i'll 1912 amounted to SSO6, 40,
OF which S71O,3S7 was obtained by
dredging. The gold won from placers
in 19l. was Sl21 1913 more than in 1911
Il tI,s.t tshl, l<.1.A
was S2O6, 1854 less. The gold recover
ed from ore treated at gold and silver
mills amounted 81 ,O39,47O, that from
concentrates amounted to $6H6 1854,
and that from crude ores shipped to
smelterS, 81, 1O9,255.
The production Of silver in Mon
tana in 1912 was 12,73l ,63S ounces,
valued at s7,s2o, ,O50, against 1l,Os5,-
1876 ounces in 1911. Nevada probably
led in silver output in in 1912, follow
ed by Utah and then by Montana.
or MOntana's output of silver, 10, $780,
O55 ounces, or S2.7 per cent, came
from copper ores and !, ,31s, ,5O5 ounces,
or about 10 per cent, from siliceOus
| ores. Bullion recovered at gold and
silver mills produced only S,443
ounces while concentrates produced
S,595, ,053 ounces, and crude ore ship
ped to smelters contained 4,O39 1923
ounces. Silver Bow county produced
1852, 1O8 ounces, or 80 per cent of
the states production, compared
with 10, ,25S, 122 ounces in 1911.
The production Of lead in Montana
increased from 6,43l,575 pounds in
1911 to 7,440,749 pounds valued al
$685., lob, in 1912. Nearly all the met
al-mining cOuuties in Montana made
a small yield of lead, but Cascade
Jefferson, Lincoln, ana Silver Bow
counties, with production OF 6.255
282 pounds III 1912, against 4,7s3, ,33:
pounds lr 1911, produced 81 per cen
of the output for the state in 10l:
and "A per cent in 1911.
Montana zinc output in 1912, re
ported rs spelter, aggregated 26,91s,
SS1 pounds, valued at $1.757, ,4O2
against ~, $40, 145 pounds in 1911. Tn
Summit Valley district, in Silve
Bow county, yielded all the sulphid
concentrates, containing 26, 7O5, ,55
pounds OF spelter, and Jefferson, Lin
coin, and Fergus counties produce
126,331 pounds, the content of sui
phide and carbonate ore shipped d
rect to eastern reduction works.
The number of deep mines prOdut
ing smetals in Montana in 1912 wa
451, against 43O in 1911, and til
number Of producing placer mine
1872. against 1870. The total quantit
Of ore sold or treated was 5,552, II
tons, and the total average recove
able value per ton of ore produce
increased from 50. .38 in 1911 to SILL;
in 1912.
