MAS/MILS sequence number 0020930009 (Bureau of Mines, 1995). Site is in Lake Clark National Park and Preserve.
Location: 6.4 km W-NW of Portage Lake, in Sec. 15, T. 5 N., R. 27 W., of the Seward Meridian. Accurate within 500 meters.
Geology: The only information is that the U.S. Bureau of Mines (1995) reported as a lode gold and silver deposit. The bedrock in the vicinity of the occurrence is Tertiary volcanic rocks. The rocks of this unit include: rhyolitic breccia, ash-flow tuff, flows, and intrusive rocks and subordinate mafic to intermediate flows (Nelson and others, 1983, unit Tv). Potassium-argon ages for this unit (Tv) range from 56.2 to 62.7 m.y. indicating a Tertiary age for these rocks (Eakins and others, 1978).
Workings: Unknown
Age: Potassium-argon ages for unit Tv range from 56.2 to 62.7 m.y. (Eakins and others, 1978) indicating a Tertiary age for the host rocks to the mineralization.
Alteration: Unknown
Production: No production
Reserves: No reserves

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