Location and accuracy This alluvial gold placer mine is on Tripple Creek, a west tributary to lower Nome River. The map location is at the approximate midpoint of placer mine tailings that extend at least 5,000 feet along the creek starting about 1 mile upstream from the mouth. The map location is at an elevation of about 100 feet in the NW1/4 section 22, T. 11 S., R. 33 W., Kateel River Meridian. The mined part of Tripple Creek is mostly on the older part of the Nome coastal plain at surface elevations are 100 to 200 feet. The mine location is accurate to within a quarter mile.

Geologic setting

Geologic description

Tripple Creek heads in bedrock on the southeast side of Newton Peak, but it mostly flows across older parts of the Nome coastal plain and the Nome River flood plain. The part of the creek on the Nome coastal plain, between surface elevations of 50 and 150 feet, has been placer mined for gold. Records of the State and Territory of Alaska show three patented claims on Tripple Creek: Kardex site Kx 167 patented to U.S. Smelting and Refining Company; Kardex site Kx 258, U.S. Mineral Survey No. 1346 (Alaska Division of Geological and Geophysical Surveys, 1982; Heiner and Porter, 1972); Kardex site Kx 305, a bedrock claim in upper Tripple Creek, reportedly located for antimony (Heiner and Porter, 1972).
Bedrock including marble and light-colored, possibly metavolcanic schist is exposed in the mine. The mine was active at least through 1997 (Swainbank and others, 1997) and is assumed still to be active in 2000.

Age of mineralization Quaternary.

Production and reserves

Workings or exploration Placer mine tailings are present along Tripple Creek between surface elevations of 50 and 150 feet. The mine was active through 1997 (Swainbank and others, 1997). In addition to placer gold, construction products have also been produced during the recent operations. The mine was assumed to be active in 2000.
Indication of production Yes; small
