Mar 20, 2007 (A Wilson) - The stratigraphic section consists of Archean-aged, steeply dipping, mafic to felsic volcanic rocks with minor amounts of interflow sediments intruded by sills and small stocks of gabbro and granites. The volcanic units have been isoclinally folded to produce a weak to very strong foliation.

Mar 20, 2007 (A Wilson) - Minor (1-5%) pyrite and pyrrhotite is present as disseminations and in fractures throughout a gabbro unit. The gabbro is weakly to moderately foliated and variably chlorite altered suggesting that it may be a subvolcanic intrusion rather than a post volcanic intrusion. The highest grade of mineralization occurs in a strongly foliated rhyolite tuff containing minor carbonate veinlets. The rhyolite becomes garnetiferous with depth.
