Minerals
While the Philippines has abundant deposits of a few mineral and
energy resources, it cannot be called rich in such resources
because it lacks many of those considered essential to a modern
urban and industrial society. It must import about 90 percent of
the fuel it consumes. By the early 1990s this accounted for
nearly 15 percent of its imports.
Unlike nearby Indonesia and Malaysia, extensive exploration for
offshore oil and natural gas has not yet revealed sufficient
quantities to justify commercial exploitation. It was hoped that
large quantities of oil would be found in the area of the Sunda
Shelf surrounding Palawan Island, but this has not yet proved to
be the case. Similarly, the small amount of coal that is mined
is not enough to have a significant impact on the nation's
energy or manufacturing needs.
The coal that exists is generally of low quality. The
Philippines does have significant amounts of hydroelectric
potential. The most notable development has been built at the
Maria Cristina Falls near Iligan on northern Mindanao. There is
also hydroelectric power on Luzon. Geothermal generating plants
have been built on Luzon and on Leyte. The Philippines is the
world's second largest producer of geothermal power, after the
United States, but this source still supplies a small share of
the nation's total energy needs.
A variety of metal ores is abundant on the islands. The most
valuable are gold, copper, nickel, and chromite, which together
make up nearly all of the total mineral exports. These minerals
are, of course, subject to fluctuations in world market prices,
so their value to the Philippines is not consistent. In 1980,
for example, these metals made up approximately one fifth of
total exports, whereas in 1983 the minerals comprised less than
one tenth of total exports. A sharp drop in commodity prices
worldwide had occurred in the meantime.
The Philippines is the largest copper producer in Southeast Asia
and is among the top ten producers in the world. Most of the
copper is mined in the North Luzon Highlands and on Cebu Island,
the site of Asia's largest single copper mine. Two fifths of the
nation's total production comes from this central Visayan
Island. Gold and silver are abundant in northern Luzon, northern
Mindanao, and on several of the Visayan Islands. Benguet
Province on Luzon is the top producer. The Philippines is also
among the world's leading exporters of chromite. Large deposits
of the mineral are found in Zambales Province on Luzon. Small
amounts of zinc, manganese, iron ore, and cobalt are produced
when world prices justify it. Undeveloped deposits of iron and
nickel are located in Surigao, northeastern Mindanao.
