Geologic information

Identification information

Deposit ID 10307271
Record type Site
Current site name Unnamed (near headwaters of Humbolt Creek)

Geographic coordinates

Geographic coordinates: -164.48342, 65.80934 (WGS84)
Relative position This occurrence is on the north side of the central headwater tributary to Humbolt Creek. Humbolt Creek is a northeast-flowing tributary to Goodhope River. The occurrence is 3,500 to 4,000 feet north of the continental divide and about 500 feet north of the the Humbolt Creek headwater. The locality is plotted separately by Sainsbury and others (1970, sample locality 23, Plate 1).

Comments on the geologic information

  • Geologic Description = Sainsbury and others (1970, Table 2) give analytical data for several rock and pan concentrate samples from this locality. It is in an area of extensive tundra cover (Till and others, 1986) and only 2,500 feet southeast of another galena-bearing locality (BN052). The possibility exists that the samples reported from here are actually from the unnamed galena-bearing occurrence closer to Humbolt Creek (BN052). However, this occurrence is described separtely in keeping with the location given by Sainsbury and others (1970). Samples from this locality are described as galena in schist, stained float below galena prospect, quartz and galena, and cemented fault breccia (Sainsbury and others, 1970, Table 2). These samples contained up to 0.2 ppm Au, 150 ppm Ag, 500 ppm As, greater than 20,000 ppm Pb, 300 ppm Sb, 300 ppm Sn, and 1,500 ppm Zn. Epigenetic mineralization in this area is interpreted to have introduced into low grade, Lower Paleozoic metasedimentary rocks over buried parts of the Oonatut Granite Complex. The Oonatut Granite is part of the western Seward Peninsula tin granite suite (Hudson and Arth, 1983) and the polymetallic character of this mineralization may be reflective of the lead-zinc zone in tin deposit systems (Hudson, 1979).
  • Age = Probably Late Cretaceous; this occurrence may be related to emplacement and crystallization of the Oonatut Granite Complex. K/Ar ages for the Oonatut Granite Complex are about 70 my (Hudson, 1979).
