Geographic coordinates

Geographic coordinates: -165.46909, 64.68908 (WGS84)
Relative position Bangor Creek is an east-flowing tributary to Snake River; their confluence is about 1.2 miles due west of the Snake River road. About 1.4 miles of Bangor Creek have been placer mined, from an elevation of about 175 feet at the edge of the Snake River flood plain upstream to an elevation of about 300 feet. The map location is at the approximate midpoint of the mined part of Bangor Creek in the southwest corner of section 22, T. 9 S., R. 34 W., Kateel River Meridian. It is included in locality 92 of Cobb (1972 [MF 463], 1978 [OFR 78-93]).

Comments on the geologic information

  • Geologic Description = Bangor Creek was placer mined for about 1,500 feet above its confluence with Butterfield Creek and for more than a mile below the confluence. Mining probably began in Bangor Creek as early as 1906 (Brooks, 1911) and continued to 1914 when a 3.5 foot bucket line dredge was built (Eakin, 1915 [B 622-I, p. 367]). The dredge had a design capacity of 2,000 cubic yards of material per day and reportedly dug down for about 18 feet. Dredge tailings on Bangor Creek contain abundant large cobbles and small boulders of quartz. Before the dredge was constructed, most of the mining was near the confluence of Butterfield Creek. In this area, the grade of the placer was reported to be about 0.12 ounce of gold per cubic yard in a deposit about 14 feet deep. Most of the gold reportedly was fine-grained but some nuggets weighed about 0.75 ounce. Hematite and scheelite were present; some scheelite occurred in pieces weighing one-half pound (Moffit, 1913). Scheelite was also reported by Coats (1944) and Thorne and others (1948). Potential lode sources for the gold and scheelite in Bangor Creek include the mineralized zone on the southeast flank of Butterfield Creek (NM191), possibly the Twin Mountain zone (NM186), and the Jarosa Ridge prospect (NM193). Bangor Creek cuts through rocks tentatively correlated with the Solomon Schist which forms the core of the Twin Mountain anticline (Bundtzen and others, 1994).

Comments on the workings information

  • Workings / Exploration = Bangor Creek was worked by surface or by shallow underground methods from at least 1910 until 1914, when a bucketline dredge was erected on the creek. The grade of the placer reported in Moffit (1913) was 0.12 ounce of gold per cubic yard. The main period of mining apparently was from 1914 until 1918 (Mertie, 1918 [B 622-I, p. 425-449]); Cathcart, 1920). The dredge made at least two parallel passes. The lower limit of pay was just above the point where Bangor Creek enters the Snake River plain.
