The northeastern region has substantial reserves of metallic mineral deposits, including chromium, copper, and iron-nickel. Large deposits of lignite (soft coal) are found near Tiranë, and natural asphalt is mined near Selenicë.
Albania is also rich in rivers and streams with significant hydroelectric potential. These have been exploited quite effectively, making the country an energy exporter. A number of huge hydroelectric power plants have been built, mainly on the Drin River, and more than half of the country's arable land is irrigated, largely from the artificial reservoirs created upstream of the dams.
