Location: The Gold Hill lode prospect is on the north bank of the Yukon River, about half a mile west of the mouth of Lancaster Creek. The site is on the border between sections 1 and 2, T. 4 N., R. 26 W., of the Fairbanks Meridian. The location is accurate within half a mile. The site corresponds to location 2 of Cobb (1972), and roughly to the site for Gold Hill, U.S. Bureau of Land Management MAS number 0020480053.
Geology: The country rocks in the area of the Gold Hill lode prospect are upper Precambrian or lower Paleozoic schist, quartzite, phyllite, and slate, and Cretaceous granite (Chapman and others, 1982). The deposit consists of a 2- to 3-foot-wide, rusty quartz vein in talcose schist (Maddren, 1910). Maddren describes this as the first attempt in Interior Alaska to develop a lode mine. Around 1890, miners began working on this vein, tunneling 110 feet into Gold Hill before abandoning their work because the vein was narrow, low grade, and faulted (Spurr, 1898). A random sample assayed 0.05 ounce of gold and 0.3 ounce of silver per ton (Maddren, 1910).
Workings: Around 1890, miners began working on this vein, tunneling 110 feet into Gold Hill before abandoning their work because the vein was narrow, low grade, and faulted (Spurr, 1898).
Age: The deposit may be genetically related to the Cretaceous granite.
Alteration: The talcose host rock of the vein may be hydrothermal in origin (Maddren, 1910).

Commodities (Major) - Au; (Minor) - Ag
