Mar 24, 2015 (Therese Pettigrew) - The iron formation is reported to be interbedded with mafic volcanics in a sequence that also includes felsic volcanics and sediments. The iron formation is extremely deformed and hosts small ragged lenticular bodies of mafic volcanics. The plunge of the minor folds is consistently steep to the northwest (AFRI 52A05NW0005).

Mar 24, 2015 (Therese Pettigrew) - Assays ranged from 23.03 to 33.02% Fe (AFRI 52A05SW0021). Magnetite-quartz (jasper) iron formation with some specularite, amphibole, garnet and intercalated andesite associated with lean iron formation and quartzite within Archean metavolcanics. This occurrence has two main areas: one 2100 x 175 ft and another 700 x 70 ft, with the iron content estimated at 25% (Shklanka, 1968).
