See also Mineral Creek (CY020). This site lies within the Yukon-Charley Rivers National Preserve.
Location: Alice Gulch is located on a northeast-flowing tributary that joins Mineral Creek about one mile southeast of Woodchopper Creek. It is location 4 of Cobb (1972; MF-390). Alice Gulch is about half a mile long; the location is arbitrarily placed at the approximate midpoint of the stream, in section 2, T. 5 N., R. 21 E., of the Fairbanks Meridian. The location is accurate within a quarter of a mile.
Geology: Alice Gulch is a tributary of Mineral Creek (CY020), where some productive mining prior to 1912 has been reported (Prindle and Mertie, 1912). Alice Gulch is underlain by Cretaceous to Tertiary sedimentary rocks (Dover and Miyaoka, 1988). As at Fourth of July Creek (CY015), Coal Creek (CY006), and Woodchopper Creek (CY038), the source of gold is probably gravels derived from Tertiary conglomerate (Cobb, 1976 [OFR 76-632]).
Workings: Surface exploration and prospecting has taken place, and there was some small production prior to 1912. More recent activity is not known.
Age: Quaternary.
Production: The only reported production was prior to 1912.

Commodities (Major) - Au
Development Status: Yes; small
Deposit Model: Placer Au (Cox and Singer, 1986; model 39a).
