Agglomerate of the Jurassic Hazelton Group is cut by east striking diorite dykes. The agglomerate is very hard and contains fragments of andesite in a matrix of feldspar and amphibole. Patches of chalcopyrite and bornite occur over 4.3 metres within the agglomerate and a sample over this length assayed 0.05 per cent copper and 3.4 grams per tonne silver (Assessment Report 2394).
