This is a Precambrian Mississippi Valley-type massive lead zinc sulfide deposit, hosted in carbonate rock, that was subsequently reworked. Almost all the marcasite pseudomorphed to pyrite. Blades, twins and even fivelings are now pyrite. The incredibly diverse forms of pyrite are unique to this locality.
Owned by Nanisivik Mines, Ltd. until 1996 after which it was sold to Breakwater Resources Ltd. It was operated from 1976 to 2002.
