Dec 07, 2005 (A Wilson) - The mapped limits of the iron formation indicate a number of discontinuous horizons. The best known sulphide mineralization within the chert-iron formation occurs where the iron formation is cut by a diabase dike.

Jun 13, 2013 (A Wilson) - The trench exposes a thinly bedded iron formation. The various phases present in the formation are sulphide-facies, pyritic-chert, pyritic-graphite shale. The surrounding unit consists of a highly strained conglomerate. To the west in a number of stripped areas, there are schistose conglomerates exposed with rusty pyritic patches. These rusty patches are also characterized by the dominance of chert clasts in the conglomerate. Similar to, though not as well developed as the chert conglomerates at the Shunsby Deposit.

Jun 28, 2016 (A Wilson) - Locally rich sulphide beds occur in the banded iron formation with trace amounts of chalcopyrite, sphalerite and arsenopyrite. These beds are up to 5 cm thick and consist of medium to coarse grained pyrite and intercalated with thin chert beds and pyritic graphitic shale. A ferricrete cap occurs over the iron formation which binds the overlying till. In the 20's up to 45% iron was obtained from some samples. Grab samples collected by the OGS in 1994 returned values of 0.11 g/t Au, 4.3 g/t Ag; 0.05 g/t Au, 3.2 g/t Ag, 0.06 g/t Au, 0.9 g/t Ag.
