Comments

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Chron age is for Host Rock.

Comment (Geology): Age = Tertiary or younger; potassium-argon ages for the host rock range from 56.2 to 62.7 m.y. indicating a Tertiary age for these rocks (Eakins and others, 1978).

Comment (Production): Production Notes = No production

Comment (Deposit): Reference point located near Thompson AG-PB-ZN claims. AU-MO occurrences nearby. Gleason Prospect (B542) assumed to be in the same area as the Thompson prospects.

Comment (Commodity): Ore Material = argentiferous galena

Comment (Workings): Workings / Exploration = Samples taken by Resource Associates of Alaska (1976) were anomalous in copper and silver. Grab samples contain up to 0.25 percent Cu and 0.17 percent Mo (Nokleberg and others, 1997).

Comment (Reserve-Resource): Reserves = Estimated reserves of 91 million tonnes (Nokleberg and others, 1997).

Comment (Geology): Geologic Description = Granodiorite stock and rhyolite (Nelson and others, 1983; unit Tv) cut by 0.64-2.54 cm thick N-S trending quartz-chalcopyrite and quartz-pyrite-arsenopyrite veins. Mineralization also disseminated in the rhyolite and granodiorite (Resource Associates of Alaska, 1976). Grab samples contain up to 0.25 percent Cu and 0.17 percent Mo (Nokleberg and others, 1997). Nokleberg and others (1997) describe the site as: a large area of dessiminated sulfides in, and adjacent to an early Tertiary dacite porphyry. Orange gossan covers over a 3 square kilometer area with extensive stockwork and zones of sericite and sulfides. The dacite porphyry has undergone extensive propylitic and silicic alteration. Potassium-argon ages for host rock range from 56.2 to 62.7 m.y. indicating a Tertiary age for these rocks (Eakins and others, 1978). ? Moxham and Nelson (1952) reported the 'Thompson silver-lead claims' occur near here and consist of arsenopyrite with a little galena (argentiferous?), chalcopyrite, sphalerite, and pyrite in a gangue of calcite and rhodochrosite. This mineralization was reported to occur in a 183 m wide shear zone in granitic rock (but authenticity unknown).

Comment (Deposit): Model Name = Porphyry Cu or Polymetallic vein (Cox and Singer, 1986; model 17 or 22c)

Comment (Reference): Primary Reference = Nelson and others, 1985

Comment (Deposit): Other Comments = Older descriptions are of questionable reliability. Locality 4 of Cobb (1972) probably the same as locality 3 of MacKevett and Holloway (1977), the Thompson claims. Site is in Lake Clark National Park and Preserve.
