The H 9 occurrence is located northwest of Clesklagh Creek on the north shore of Holberg Inlet.

The area is underlain by andesitic volcanics of the Lower Jurassic Bonanza Group and minor sediments of the Lower Cretaceous Queen Charlotte Group, Longarm Formation.

Pyrite and minor chalcopyrite are present in silicified tuff of the Bonanza Group on the H 9 claim in a small creek. Further up the creek, andesite flows and agglomerate contain up to 20 per cent disseminated pyrite. This zone is observed over an area of 120 by 180 metres and up to 15 metres thick, striking 290 degrees and dipping to the southwest with the slope of the hill.

Siltstone and sandstone of the Longarm Formation are located nearby, along the shore of Holberg Inlet.
