Location: Timber Creek is a northwest-flowing tributary of Poorman Creek. Coordinates given correspond to location 35 of Cobb (1972 [MF405]) and represent the approximate center of mining activity, in section 36, T. 16 S., R. 16 E., Kateel River Meridian. The location is accurate within a quarter mile.
Geology: The bedrock in the valley walls above Timber Creek is composed of Innoko terrane chert and slate (Puchner and others, 1998). Drilling indicates the presence of a fault at the juncture of Bonanza and Timber Creeks (Pete Haggland, oral communication, 2000). The center of mining activity was just below the mouth of Flat Creek (a tributary), and no workable deposits were located upstream from Flat Creek. Flat Creek possibly cuts a northeast-trending mineralized zone, and abundant barite was found in concentrates from near the mouth of Flat Creek (Cobb and Chapman, 1981). Intermittent mining took place along Timber Creek from 1916 until about 1992 (Eberlein and others, 1977; Swainbank and others, 1993).
Workings: Timber Creek experienced intermittent mining and exploration from 1916 to about 1992. A reverse circulation drill program was conducted along Timber Creek in 1990 by Howard Miscovitch (Swainbank and others, 1993).
Age: Quaternary.
