Geology: Tatalina Creek which has its headwaters near VABM Tatalina, flows about 2 miles north-northwest to Carl Creek. Unpublished U.S. Mint records indicate prospecting in Tatalina Creek in 1917 and 1918 and the production of about 18 ounces of placer gold. However, the location of this production is uncertain (Wimmler, 1927). Heavy-mineral-concentrate samples were collected by Bundtzen, Cox and Veach (1987) in Tatalina Creek at an elevation of about 1,200 feet. The samples contained anomalous values of lead, silver, arsenic, and gold; the heavy minerals in the samples include magnetite, galena, ilmenite, crossite, and fluorapatite (Bundtzen and others, 1987). The base-metal deposit in tourmaline hornfels upstream near VABM Tatalina (ID044) is the possible source of the anomalous samples in Tatalina Creek.
Workings: There are old placer tailings in Tatalina Creek. Panned-concentrate samples were collected by the Alaska Division of Geological and Geophysical Surveys in 1978 and by the U.S. Geological Survey in 1985 (Bundtzen and Laird, 1983; McGimsey and others, 1988; Bennett and others, 1988). Anaconda Minerals Company took stream-sediment samples in Carl and other tributary creeks in 1981; they reportedly contained five to ten times above background values for lead, zinc, and silver (D.B. Obolewicz, written communication, 1981).
Age: Probably Quaternary.
Production: Unpublished U.S. Mint records show that Tatalina Creek was prospected in 1917 and 1918 and about 18 ounces of placer gold were recovered (Wimmler, 1927).
