  485The Mineral Industry of Montana 
 
 
This chapter has been prepared under a cooperative agreement between the
Bureau of Mines, U.S. Department of the Interior, and the Montana Bureau
of Mines and Geology for collecting information on all minerals except fuels.

 
 
By Fred V. Carrillo,1 Ronald P. Collins,2 and William N. Hale' 
 
 
 In 1967 Montana mineral production was valued at $186.5 million, a decline
of $58.7 million from the prior year resulting mainly from a nationwide labor
dispute that idled the copper industry at midyear. Chiefly as a consequence
of the strike-caused curtailment of operations at The Anaconda Company, copper
production value was down $42.6 million; silver production value decreased
$3.7 million; and lead and zinc values declined $1.1 and $7.5 million, respectively.
The lead and zinc values also were affected by termination of mining at the
Badger State mine 
and cessation of operations at the Anaconda zinc smelter. 
 The value Of peti~oleum production amounted to a record-setting $87.5 million;
petroleum was also the State's dominant mineral commodity in terms of value.
The combined value of petroleum and copper production continued to grow when
considered as a percentage of total value— 70.7 percent in 1965, 72.9
percent in 1966, and 73.8 percent in 1967.
