General comments

Subject category Comment text
Deposit Model Name = Cinnabar-quartz vein.
Deposit Other Comments = This site was referred to as the 'Hudson Cinnabar' prospect in Nokleberg and others (1987), but it is in a different location than the Hudson cinnabar mine on Olive Creek (ARDF no. LG015).
