Comments

Comment (Geology): Age = Quaternary.

Comment (Exploration): Status = Not determined

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)

Comment (Workings): Workings / Exploration = Surface and underground workings. Mostly small-scale drift mining in the old channels. Gold was discovered on Little Squaw Creek in 1905, and mining was reported in most years through 1940, with further activity noted as late as the mid-1980s. In 1983, bulk sampling indicated average grades of $11 to $16 per cubic yard (gold at $400 per ounce) (Alaska Construction and Oil, 1984). Average fineness of the gold was reported as 848 (Mertie, 1925, p. 258).

Comment (Reference): Primary Reference = Mertie, 1925

Comment (Reserve-Resource): Reserves = Alaska Construction and Oil (1984) reported that Canadian Barranca Ltd., Inc., the operator in 1984, considered placer reserves in Tobin Creek, Little Squaw Creek, and two additional unnamed creeks in the area to be at least 100,000 ounces with potential for as much as 500,000 ounces.

Comment (Deposit): Other Comments = See also: Big Creek (CH043), Tobin Creek (CH048), Mikado Mine (CH045), Little Squaw Mine (CH040). Placer concentrates contain 0.002 to 0.003 percent eU (White, 1952).

Comment (Production): Production Notes = Significant production but exact figures are unavailable.

Comment (Geology): Geologic Description = Little Squaw Creek drains an area of auriferous quartz veins of the Chandalar district (CH040 through CH042) that are the presumed source of the placer gold. Mertie (1925, p. 254-259, 263) described the complex glacial history for the creek. The creek was dammed by ice in the North Fork Chandalar River valley during part of Pleistocene, and this damming resulted in both pre- and post-glacial channel and bench deposits along Little Squaw Creek. The creek and bench gravels are mixed, with no distinct boundaries. The upper part of the drainage is described as having gold on bedrock, while farther downstream the pay streak runs onto false bedrock in glacial gravels (Mertie, 1925). Post-glacial deposits, mainly along the lower course of the stream, are composed of 25 to 50 ft of glacial till overlain by 55 to 100 ft of gravel. The pre-glacial deposits, mainly along the upper stream course, are about 35 ft deep, with coarse gold in the upper 2 to 3 ft of bedrock. The placer concentrates contain, in addition to gold, a variety of other minerals, including pyrite, hematite, arsenopyrite, scheelite, galena, and monazite.
