The Bureau of Mines investigated reports of mineral deposits within 10 miles of the route of the proposed pipeline from Prudhoe Bay to Valdez. No producing lode deposits or lode prospects of possible national economic significance were found. Measured placer deposits in the route are of slight value except possibly some deeply buried gold placer deposits in the Fairbanks and Livengood quadrangles. The pipeline corridor crosses five belts of minerals, having potential economic value: (1) the north slope of the Brooks Range (oil, gas, oil shale, coal, phosphate); (2) the south slope of the Brooks Range (copper, gold); (3) the Livengood area (gold); (4) the Fairbanks area (gold, lead-silver, antimony); and (5) the Wrangell Mountains-Denali copper belt (copper-gold). The Jarvis Creek coalfield, an eastern extension of the Nenana coalfield, is on the north side of this belt. Scattered along the corridor across the Chugach Mountain and in the vicinity of Valdez are a wide variety of metallic deposits that make up the eastern margin of the Chugach gold belt but do not seem to constitute a well-defined zone.
