 Although world mine production of copper fell in~1978, demand increased
significantly, reducing the large excess of copper stocks built up in the
preceding 3 years. In 1979, world copper production improved slightly, demand
continued to increase and world stocks were further reduced. A number of
new mines came onstream in 1979 and excess capacity at some operations began
to be utilized. The United States 
continued to lead the world in mine output with about 19% of the total in
1979, followed by Chile, the U.S.S.R., Canada, Zambia, Peru Zaire Poland
the Philippines Aus tralia and the Republic of South Africa Labor strikes
adversely affected Canadian copper production from late 1978 to mid1979 and
production in central Africa was curtailed during both years owing to politi
cal economic and transportation problems
