Agriculture in the Northwest Territories
is virtually impossible except for limited
cultivation south of the Mackenzie River
Trapping, the region's oldest industry,
ranks second after mining.
A thriving commercial fishing industry,
based on whitefish and lake trout, is
centered on the village of Hay River, on
Great Slave Lake.
Minerals are now the Territories' most
valuable natural resource. Oil is pumped and
refined at Tulita (formerly Fort Norman) and
Norman Wells on the Mackenzie River; copper
is extracted on the
Coppermine River; and diamonds and gold
are being produced in increasing quantities.
The region also has tungsten, silver,
cadmium, and nickel. Important hydroelectric
developments are on the Talston and Snare
