Location and accuracy Kapon Creek is an east tributary to the Eek River. The mouth of Kapon Creek is 9.5 miles downstream of the mouth of Rainy Creek (BH002) on the Eek River. This placer mine was referred to under the name 'Kapon Ck.' by Hoare and Cobb (1977). The map site is in the SE1/4 of section 6, T. 1 S., R. 63 W., of the Seward Meridian. It is approximately located, perhaps within miles, as the headwaters of this creek are about 4 miles further upstream from the map site.

Geologic setting

Geologic description

Placer gold mining along Kapon Creek is reported to have taken place in 1914 and 1915 (Hoare and Cobb, 1977, p. 18). The lower part of the creek is in a glaciated area of outwash deposits. The upper reaches do not appear to have been occupied by glaciers but some outwash deposits may be present. The extreme headwaters of Kapon Creek are across a narrow saddle from the headwaters of Rainy Creek (BH002), where lode cinnabar mineralization has been identified (BH001). Coarse gravels in Kapon Creek were ground-sluiced in 1914 and found to be of low grade (Maddren, 1915, p. 357). The gold was dark and flaky and accompanied by magnetite, arsenopyrite, and small cinnabar pebbles. Bedrock in the Kapon Creek drainage is clastic sedimentary rocks of the mid-Cretaceous Kuskokwim Group locally cut by felsic and mafic dikes (Hoare and Cobb, 1977; Box and others, 1993).
