| 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 descriptionLow-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). | |

|---|---|
| Age of mineralization | Late Cretaceous or younger; mineralization is hosted by a Tertiary to Late Cretaceous tonalite. |
| 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 commentsInformation 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. | |
