pared with that of 1978. The value of iron production also decreased for
1978-79, compared with that of 1977. 
 Silver.—The principal source of silver, accounting for approximately
78% of the State's total output in 1978 and 80% in 1979, was silver that
was produced as a byproduct from Anaconda's Berkley Pit in Silver Bow County.
In 1978 and 1979, production of silver outside the Butte area amounted to
637,000 and 646,000 troy 
ounces, respectively. Production in 1979 was from 31 mines in 14 counties;
in 1978, silver production was from 25 mines in 9 counties; and in 1977,
production was from 29 mines in 12 counties. Montana ranked fourth among
the producing States in the production of silver in 1978 and third in 1979.
About 7% of the newly mined silver production in the United States during
1978 came from Montana mines; in 1979, Montana's share was approximately
9%.
