Figure 2.—Mine production of copper and zinc in Montana, by months,
in terms 
of recoverable metals. 
 
Workers in the trades, services, and related sectors were on short work weeks.
Many highly paid skilled laborers, estimated at 500 from the Butte area,
had left the State to find employment in other industrial sites on the west
coast. Wages lost to the economy in the 5½-month period from July
15 to December 31 were estimated at $23.5 million. 
 
 Government Programs.—The Office of Mineral Exploration (OME) approved
three new contracts and continued three 
earlier contracts already in effect. Silver Queen Exploration received a
$51,600 contract to begin work in 1967 at a Beaverhead County silver property
(Silver Queen claims). Development Operating Corp. gained approval of a $90,000
Jefferson County silver project to begin work at the Elkhorn mine in 1967.
Work in Madison County was to be conducted by Janus Mining Co. at a gold-silver-copper
ore property (Janus Group) under an $87,600 agreement.
