Location: Several miles of placer claims were staked in 1889 along Chunilna Creek and a north fork of it. The claims extend more or less continuously from sec. 23, T. 30 N., R. 2 W. to sec. 21, T. 29 N., R. 2 W., Seward Meridian. The coordinates are near the center of these claims in the SE1/4 sec. 35, T.30N., R. 2W., Seward Meridian. The location is accurate to within 1/2 mile.
Geology: Gold occurs in alluvial gravel deposits along Chunilna Creek and a north fork of it (Paige and Knopf, 1907; Carnes, 1976). The rocks along the creek are tightly folded Lower Cretaceous(?) argillite and lithic graywacke intruded by Tertiary biotite granodiorite (Csejtey and others, 1978). Several miles of placer claims were staked in 1889 (Paige and Knopf, 1907). This is the only placer mine in the Talkeetna Mountains quadrangle that operated during 1975 (Carnes, 1976). As of January 1, 2000, the mine was inactive but still covered by placer claims (Northern Associates, Inc., written commun., 2001). Minor production reported in 1975 (Carnes, 1976).
