108 MINERALS YEARBOOK

producer in the United States in 1932. The 500-ton flotation plant was worked
regularly and the company paid four quarterly dividends aggregating $150,000.
Large increases in the output of silver were also made from the Crescent
on the west side of Big Creek and the Golconda Mines east of Wallace, but
unusually large decreases were reported from the Morning, Hecla, Bunker Hifi
& Sullivan, HallInterstate, Page, Blackhawk, Dayrock, and Sherman Mines.
 Gopper.—The output of copper decreased about 4 percent in 1932, and
the value decreased from $104,187 to $66,917 as the average price of the
metal ' decreased 3 cents a pound.
 About half the copper produced in Idaho in 1932 came from the Suflshin~
(Yankee Boy) property, as the chief mineral in the ore of this' important
producer is a variety of tetrahedrite carrying con~ siderable silver as well
as copper. It was followed by the Bunker Hill & Sullivan and Ilecla properties,
where a small quantity of copper is associ~ted with lead ore. The regular
copper producers in Idaho, such as the Mackay Metals Co., operating property
in Custer County, and the Winder-Stiiman Con, operating property in Lemhi
Couhty, have been closed since the drop in the price of copper in 1930.
 Lead.—The' output of lead in 1,932 decreased about 28 percent from
that in 1931, and the value of the output decreased from $7,352,981 to about
$3,976,000 as a result of general curtailment of produetion caused by a continued
drop in the average prices of lead and iinc.
 Idaho suffered particularly from the extremely low price of lead, as the
State produces about 25 percent of the lead produced in the United States.
The State, however, maintained its position as the second largest producer
of lead in the United States, after Missouri.
 The Bunker Hill & Sullivan, Hecla, and Morning Mines were as usual the
three largest producers, but the total output of these mines was 26 percent
less than that in 1931; the output from the Morning Mine alone decreased
more than 20,000,000 pounds, as the property was closed 5 months of the year.
Other large producers of lead in 1932 were the Page, Golconda, Sidney, and
Whitedeif properties. According to the annual report of the Blinker Hill
& Sullivan Mining & Concentrating Co. for 1932 the company mined
and treated 429,880 tons of ore compared with 460,366 tons in 1931. The Bunker
Hill smelter and refinery were operated on a 1-furnace basis and produced
60,283 tons of lead, 8,528,772 ounces of silver, and 34,760 ounces of gold
compared with a production of 77,687 tons of lead, 10,049,526 ounces of silver,
and 44,841 ounces of gold in 1931. The sharp decreases indicate a marked
reduction in both company and custom materials received at the plant. Dividends
paid in 1932 amounted to only $61,637 compared with $553,246 in 1931 and
$2,109,690 in 1930. Ore reserves at the end of the year were 2,118,273 tons,
and mine development was limited to the new Flood-PikeStanly area where important
new reserves of ore were opened. The electrolytic zinc plant of the Sullivan
Mining Co., which is worked under the control of the Bunker Hill & Sullivan
Mining & Concentrating Co., operated continuously during 1932 at about
29 percent of capacity. Although virtually all the important producers of
lead in Idaho decreased their output decidedly the Golconda Lead Mines increased
its output nearly 1,000,000 pounds.
 Zinc .—T he zinc recovered from ore and concentrates in 1932 decreased
about 47 percent from that in 1931, and the value de
