 A decline in lead and zinc prices resulted in decreased output of lead and
zinc concentrates produced from ore mined in the Tn-State District. Lead
was priced at 14 cents per pound throughout the year and zinc at 13.5 cents
per pound after June 20, and thus were below the 14.5 cent price at which
payment is made to qualified producers of lead and zinc under the small mines
stabilization pro- 
gram. Public Law 89—238, as emended October 5, 1965, made the producers
eligible to receive payment. 
 Prices quoted in Metals Week on 60 percent zinc concentrates at Joplin,
Mo., declined from $92 per ton to $86 per ton on May 15, to $84 per ton on
July 3, and remained at that level for the remainder of the year.
