 Mineral exports in 1978 increased both in tonnage and value and, with a
value of $970 million, represented 50% of all exports. 
Copper ranked No. 1 in export value, and silver ranked No. 2. They accounted
for 42% and 21%, respectively, of the value of mineral exports. In 1979 mineral
exports were valued at $1,548 million or 45% of total exports. The bulk of
Peru's mineral exports is in the form .of metal. However, 
the country still exports lead and zinc concentrates and will continue to
do so even with the completion of the Cajamarquilla refinery.

agency in charge of marketing all Peruvian minerals, were as shown in the
