Location and accuracy 1,000 ft north of the unnamed lake that is the headwater of Reed Creek, a tributary of Archangel Creek. Accurate within 2,500 ft. Locality 33 of Cobb (1972) and locality 24 of MacKevett and Holloway (1977).

Geologic setting

Geologic description

Low-grade molybdenum-copper mineralization, probably in a pegmatite dike that cuts Tertiary to Late Cretaceous tonalite (Jasper, 1967). Downstream, samples (locality 85 of Cobb, 1972) in stream gravels contain scheelite (Jasper, 1967).
Geologic map unit (-149.152204731311, 61.8494735684933)
Age of mineralization Late Cretaceous or younger; mineralization is hosted by a Tertiary to Late Cretaceous tonalite.

Production and reserves

Workings or exploration Explored by adit driven in 1917, which is now largely covered by talus (Jasper, 1967). Data on prospect is limited.
Indication of production None

Additional comments

Information on deposit is very non-specific. Mackevett and Holloway (1977), assumed deposit to be a pegmatite carrying molybdenite and chalcopyrite probably on the basis of regional geology. Other references mention only low-grade molybdenite-copper mineralization.
