Dec 07, 2005 (A Wilson) - Some of the sulphides present are hosted in cross fractures and the best mineralization is located adjacent to a diabase dike. The rocks are generally schistose.

Jun 13, 2013 (A Wilson) - The host rock consists of interlayered cherts, a finely laminated white phase and a dark green phase. These are cut by some quartz veins. The chert horizon is about 3m thick and bordered by a mafic volcanic on one side and a mafic intrusion on the other. At Trail Creek, the mineralization is next to a diabase dike that cuts the iron formation.

Jun 13, 2013 (A Wilson) - At the Trail Creek prospect, heavy pyrite and arsenopyrite mineralization occurs in a quartz vein within the iron formation. Other quartz veins in the area contain low concentrations of sulphides. More typically, sulphides occur in discontinuous trails along fracture surfaces. The fine-grained magnetite in the iron formation, occurs in narrow lamellae, together with thicker chert lamellae. Low concentrations of very fine grained pyrite and trace amounts of chalcopyrite are disseminated within the banded iron formation, or occur in short aggregate streaks. Arsenopyrite also occurs in trace amounts within the chert, but tends to be coarse grained. East of the Trail prospect, low concentrations of pyrite occur in fine-grained trails parallel to bedding in the chert, as well as in coarser grained veinlets that are discordant to the bedding. These veinlets are semi-massive, and contain trace amounts of sphalerite. Further along strike, adjacent to a diabase dike, pyrite and arsenopyrite form up to 30% of the chert beds which are 2-3 cm thick. At this location, remobilized sulphide veins also occur. In 1950, Central Manitoba Mines reportedly obtained an assay of 4.4 g/t Au from the iron formation. The best assay obtained by Cominco in 1979 was 0.2 g/t Au from a diamond drill hole. Grab samples collected by the OGS in 1994 returned disappointing results.
Jun 13, 2013 (P Bousquet) - Augen Gold Corp. sample 521779 returned an anomalous assay of 1110 ppm Ni (T-5852), but no assay scored high on gold.
