No significant gold is reported, but it is not clear how many samples were analyzed for gold.
Workings: This occurrence has only had limited surface sampling.
Age: Devonian or younger, on the basis of the age of the host rock, which is in the Jarvis Creek Glacier subterrane (Nokleberg and others, 1992).
