Geology:
The Berens River Mine property is underlain by a sequence of folded metasedimentary and metavolcanic rocks that strike north-south and dip steeply to the east. The metasediments are reported to consist of laminated chert, argillite, siltstone, fine-grained tuff, marble and banded iron formation (Whittaker 1989), while the metavolcanics were mapped by Ayres (1970) as consisting largely of felsic lapilli tuff and tuff breccia. These rocks form part of the 2926 Ma Setting Net Assemblage of Thurston et al. (1991). The supracrustal rocks were subsequently intruded by a mafic intrusion that occurs immediately to the west of the mine property, while a north-northeast striking diabase dike has been mapped immediately to the east. Significant structures that have been mapped in the vicinity of the mine site include an approximately north-south-striking fault to the west, and an approximately north-northwest-striking fault located to the east.
