From 2002 to 2005, Delta Junction experienced an economic boom similar to the pipeline days as Fort Greely became fully operational again and the missile test bed was constructed. National firms such as Boeing, Bechtel, and Brown and Root, as well as regional firms including Chugach opened up offices on the installation, under contract to the government. Construction of the Pogo Gold Mine just north of Delta Junction, near the Goodpaster River, also contributed significantly to the economic fortune of the city. Mineral deposits near Tangle Lakes, south of Delta Junction, will likely result in additional development of mining in the area.
