METAL OUTPUT Of
MONTANA MINES
Lead and Zinc Production
Last Year Greater Than
Year Before.
OTHER ORES DECREASE
Output Valued at Over Forty
Eight Millions of
Dollars.

The value OF the mine output OF goic
silver. copper. lead and zinc IN Montaha
in 1910. according TO v c. Heikes OF the
United states geological survey. Was $is,-
s5s. a53. against s5l, f2o,69i In 1909, de
crease of SOL $40, occasioned almost en-
Iircly by the Iessened output Of copper
ores. The value OF the gold. silver and
copper combined was s4.S26,Sss less than
IN 1909. while the value of the lead and
zinc yield was S1.255.427 moro than In
1909. The value OF the production OF Sill
yer Bow county. which includes the Butte
district, was et per cent OF the total value
of the metals from Montana. The de-
crease in value in this county was ~,
16s.Ss1 so that tho combined production
OF the other counties in Montana was
slightly greater in 1910 than In 1909,
The production OF gold In 1910 was only
s1.o24 less than in 1909. The greater
part or the gold. 115 .o6l 0s fine ounces or
81 per cent of the total. was from silceous
ores: and 3t,44i.95 ounces: or J! per cent;
came from copper ores. The placer gold
In 1910 amounted 10 sSI5,al7. OF which
s473ss6 was obtained by dredging. The
gold won from plscers was Sa2,0ib greater
than in 1908. but that taken from lode
mines was s95.56e less.
The production Of silver in Montana
In 1910 was l2.l62.s37 fine ounces. against
1c.37S.71l ounces in 1909. Nevada now

held in the years 1909 and 1908. OF
Moutana's 1910 output Of silver, 9,la5,5?0
ounces, or 80 per cent. came from copper
ores, and 2.l5s f65 ounces. or lI6 per
cent, from siliceous ores. Bullion al sold
and silver mills produced only 10000
ounces. while concentrates produced g
2os.s .s4i~ounces and crude ore shipped to
smelters contained 3.1s6.575 ounces. Sill
yer Bow county produced 10. 400 $50 ounces

The number OF deep mines producing
metals in Montana in 1910 was 49,
against AS IN 500 and the number Of
producing placer mines vas l51 against
10. The average total recoverable value
