/ TIME VALUE of the gold, silver,
copper, lead and zinc mined in
Idaho in 1920, according to the
estimate of c. n. Gerry of the
United States geological survey, de-
partment of the interior, was about
$32, 144OOO an increase of $13,77O,OOO
from that in 1919. The shipments of
ore and concentrate showed marked
increase over those in 1919, when the
Occur d'Alene district suffered on ac-
count of a labor strike Though the
output of gold and copper decreased,
the output of silver, lead and zinc in
ci eased greatly. Production was not
normal, but the large mines were ac-
tive and the prices for lead and zinc
We're somewhat higher. The Bunker
Hin smelter at Bradley, was active
throughout the year, and the produc-
ton of silver and lead was an encour-
aging feature of the mining industry
The lead plant at Northport, Wash.
was again in operation and treated
material from the Hercules and Tam
arack & Custer mines, near Wallace.
Gold.
The mine output of gold in Idaho in
1920 was valued at about S469OOO,
large decrease from that in 1919,
which was valued at $71S,2sS. The
largest output of gold was made by
the Gold Hill & Iowa property at
Quartzburg. The dredge of the Yukon
Gold company at Murray, in Sho-
shone county produced considerable
gold, but was idle for a time on ac-
count of the sinking of the dredge
The Holte mine, in Idaho county, was
not productive, and the Mullen dredge
IN Lemhi county, could not be operat-
ed on account of high costs.
Silver.
The mine output of silver increased
from 5,579,O56 ounces in 1919 to about
I545,O 900 ounces in 1920, or more than
So per cent, and the value increased
from S6.24S,543 to about 1927, 900.
The largest silver producers in the
state We're the Hercules, at Burke;
the Bunker Hill & Sullivan, at Kel-
Iogg; the Hecla mine, at Burke; and
the Morning mine, near Mullan. 9th
en- large producers of silver were the
Gold Hunter Tamarack e Custer
Interstate, and Caledonia
mines. The mines in the Occur
rAlene district produced about g.
100000 ounces of silver, or about SO
Der cent of the total for the state.
Copper.
The mine output of copper decreas-
I'd from 3,122,763 pounds in 1919 to
bout 2,2OS,OOO pounds in 1920 The
'alue of the output decreased from
$50, SS4 to about $4,000. The EN-
ire Copper company. at MaclSay, was
he largest producer of copper. but its
utput was low as compared with
,ast years. The National Copper mine
,ear Mullan and the Richmond mine
ear Adair, were idle. Several hun
red tons of copper ore and concen-
rate was shipped from the Harmony
nd other mines in Lemhi county
Lead.
The mine output of lead, which is
he most abundant metal in Idaho.
increased from 1S2.3l1S9S pounds in
SO to about 25A662,O 900 pounds in
900. The average price of lead was
igher, and the value of the output
lcreased from $9,664,121 to about
90 777OOO Though the total produc-
on shows a great improvement over
hat Of 1919. the mines have not gen
rally returned to a normal output In
900 as in past years. the Bunker
Till mine produced much more lead
han any other property. Five other
lines each produced more than TO-
10000 pounds of lead-the Hercules
Ieela, Morning, Consolidated Inter-
tate Tamarack & Custer and Gold
Iunter mines The Occur d'AIene
istritc alone produced about 242,OOO,-
DO pounds of lead. Large quantities
lead ore and concentrate were also
lipped from the Tdaho-C Continental.
