The Blitz area is largely underlain by andesitic tuffs of the Middle Jurassic Hazelton Group (Smithers Formation) and by felsic volcanic rock of the Eocene Ootsa Lake Group.

The Blitz North is hosted within a prominent east northeast trending shear zone in a creek (Blitz Creek), draining into Troitsa Creek, pods, lenses and breccia fillings of arsenopyrite, pyrite and a grey sulphide have been noted. This mineralized zone is traceable for in excess of three kilometers on strike and has been sampled in three localities. Mineralized zones are in excess of 2 metres wide. Gold values tend to be consistently anomalous in the 0.5 to 1.5 grams per tonne range, with values up to 10.28 grams per tonne noted (Assessment Report 17654). Silver values are low. The Blitz Knob showing comprises a zone of silicification of lapilli tuff within a north northeast trending fault zone. Silicification zones measure up to 3 metres wide, and contain disseminated to massive stibnite and marcasite.

The Blitz Knob-Blitz North zones defines a 1900 metre long, 015 degrees trending zone of silica-sulphide breccia with strong arsenic and antimony values. The north-eastern end contains locally strong pyrite and silica altered Hazelton Group(?) volcanic rocks associated with more widespread disseminated pyrite and late quartz veins. The alteration and mineralization in this area is similar to the Wolverine zone.

In 2005, samples from the Blitz Knob zone yielded up to 0.976 per cent antimony (McRoberts, S.S. (2009-05-01): Summary Report on the Troitsa Property).
