WORLD war INJURIES
MONTANA Mine YIELD
Decrease of $14,050,799 Due to
Strife-GoId Produced in 1914
Equals $4.Il7.9ll.

Montana's mine yield Of gold, silver,
! copper. lead, and zinc in 1914 was valued
at s47Si9747, against SCI, 0o,546 in 1913,
according to Victor c. Heikes. OF the
United States Geological Survey. The
decrease, sH,O5O799, was due principally to
! the curtailment of the copper output
caused by the European war, which af-
| fected prices and the State production.
The value of gold and zinc combined was
! 81, 349, 1874 greater than in 1918, and the
value of the silver, lead. and copper was
| sl5 iO0.193 less than in 1919. Silver Bow
County produced 90.11 per cent of the
| total but the decrease in the value OF
the metallic output of this country was
| Sl4.4i6, $50
| The gold produced in Montana from
placers and from ores in 1914 was val
ued at s4,lI7.sll. against S. 493. 1872 in 1913.
OF the 1893, 2O3 81 ounces of gold produced.
~. 599. 10 ounces or 6l.Ci per cent, were
obtained from dry Siliceous ores,
against 92.749.l9 ounces in 1913. The plac-
| ers yielded 45,579 % ounces. or 22.SS per
cent of the gold. and the copper ores
yielded q. 4226 81 ounces. or le.76 per cent.
The value of the placer gold produced in
| 1914 was S9i2217. Of which $685., SIS was OBJ
tanned by the operation of five large
placers in 1914 was S1l.2l5 greater than
in 1913 and that obtained from deep or
lode mines increased S4S3. CyaniGa-
ton and amalgamation mills produced
bullion containing sSl9.4ii in gold: con-
ccntrates recovered at concentration mills
produced s5I3. 400 and crude ore shipped
to smelters produced S.S02,SN.
The production of silver in Montana in
1914 was l2.0lG 400 ounces, against 1889 POI
an in no f,ta .i..1H nf
in 1914. >.Ol5,694 ounces came from copper
! ores. AGAINST l0.3ll.SO7 ounces in 1913. and
l.2i9.JlJ ounces came from dry or sill
ccous ores. CyanidatiOn and amalgama-
ton mills yielded bullion containing $780,
col ounces of silver; concentration mills
produced concentrates containing S,356ni
ounces: and crude ore shipped TO smell
tiers contained 352s.4o7 ounces. Silver
Bow County produced 1e,5il,032 ounces, or
S.i7 per cent. OF the silver produced in
1914, against 12,2ll,725 ounces In 1918.
The production of copper in Montana
decrea sed from oS7. SOS 600 pounds in 1913
to 80, 229, 6iO pounds in 1914 Silver Bow
County contributed all the output in 1914,
except 1,O4l.0l2 pounds. Broadwater
County ranked second. contributing 1884,
977 pounds in 1914. against 39s, 79I pounds
in 1913. The copper output of mines in
jefferson County decreased from S14 1854
The lead derived from Montana ores in
1914 aggregated 9656, Dos pounds, against
0.935.S27 pounds in 1913 and 7,ii6, 749
pounds in 1912. OF the output in 1914
5"TS per cent was derived from mines in
Silver Bow County. which produced $780,
$50 pounds in 1914, aginst 4.5i2, 225 pounds
in 1913. This lead was derived largely
from lcad-Zinc sulphide ores. from which
lead is separated by concentration.
From zinc and lead-ZiDc prOdurad
in Montana. ,54 pounds of smelter
was obtained in 1914, aginst SS,6I3 OS5
pounds in 1913. This output was obtained
almost wholly from two mines at Butte,
but it includes a small production cred
:ted to jefferson County, consisting of
zinc concentrate derived from tailings
originating in Butte district. Several
shipments of ore We're made in 1914 to
zinc plants from Missoula, Meagher, and
Cascade counties.
The ore producers in Montana num-
bered 35S in 1914 against 49, in 1913 and
the number of producers Of placer gold
was 1R against l2s In 1919
