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.
Location: 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).
Geology: 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).
Workings: Explored by adit driven in 1917, which is now largely covered by talus (Jasper, 1967). Data on prospect is limited.
Age: Late Cretaceous or younger; mineralization is hosted by a Tertiary to Late Cretaceous tonalite.
