The Grizzly area is underlain by Devonian metadsedimentary and metavolcanic rocks of the Stikine Assemblage. The Devonian Forrest Kerr Pluton is in contact the immediate west of the Stikine rock. Plutonic rocks consist primarily of Late Devonian granite and diorite.

This Grizzly showing is characterized by a 15 to 50 centimeter wide, partly brecciated quartz-carbonate vein, oriented at 054 degrees and dipping 76 degrees west, containing semi-massive to massive chalcopyrite hosted in a green-grey phyllite (altered volcanic?). Hand trenching (10 square metres) has shown the occurrence to be faulted off to the south and narrowing considerably to the north with an exposure length of 3.5 metres. Detailed sampling yielded values up to 1.0 gram per tonne gold over 1 metre. A select grab sample assayed 1.2 grams per tonne gold, 80.2 grams per tonne silver and 6.81 per cent copper (Assessment Report 24156).
