Value af mineral production in Wisconsin in 1967 established a record high
of $79.6 million, an increase of nearly 5 percent over that of 1966. Nonmetals
represented about 89 percent of the total mineral value and metals nearly
11 percent. Value of metals produced increased 10 percent, and values of
nonmetals increased 4 percent, from that of 1966. Increases in quantity and
value were recorded for lime, sand and gravel, stone, and zinc. The output
of abrasive stone, portland and masonry cement, clays, lead, and peat decreased
in quantity and value from that of 1966. Higher average unit values were

recorded for all mineral commodities except masonry cement, lead, stone,
and zinc. 
Mineral production was reported from 71 of the 72 counties in Wisconsin,
again led, in descending order of value, by Waukesha, Manitowoc, Lafayette,
Milwaukee, and Marathon. Collectively, these five counties provided 38 percent
of the State mineral value. Mineral production exceeded $1 million in 20
counties compared with 17 in 1966.
