Dec 17, 2018 (Therese Pettigrew) - The stratigraphy consists of mafic metavolcanics and metasediments to the south, followed by a quartz-feldspar sill (3 m wide) with lenses of graphitic schist, followed by the barite unit. This is overlain by a sericitic schist (with abundant green mica), graphitic schists, and metasiltstone. Further to the north (1 km), metapelites containing garnet, staurolite, and andalusite are exposed (Patterson, 1984).

Dec 17, 2018 (Therese Pettigrew) - The occurrence has been trenched, exposing a unit of massive barite 1 to 2 m thick, with a strike of 110 degrees, and dipping 80 degrees S, for 60 m. The massive barite is pale grey-white in colour with poorly developed bedding of carbonate- and pyrite-rich layers, 1 to 2 mm thick, that make up <10% of the rock. Gold assays are generally <400 ppb Au (Patterson, 1984). Barite forms the major constituent of the zone and assay results greatly exceeded visual estimates. Barite grades calculated across all the trenches were estimated between 25.23% Ba over 3.75 m to 10.86% Ba over 6.1 m. A series of grab samples taken prior to the trenching returned assay values of up to 37.74% barite and 0.016 oz/t Au. A grab sample taken by George Patterson. Regional Geologist (O.M.N.R.), Thunder Bay yielded a value of 0.12 oz/t Au but this was not repeated in the systematic trench sampling by Northern Eagle (Assessment file 42D09NE0184).
