Jun 14, 2019 (Therese Pettigrew) - Immediately south of Shy Lake, the metasediments are pelitic in composition with mineral assemblages of biotite, garnet, and staurolite. A magnetite slate consisting of beds of massive magnetite intercalated with quartz-rich beds is found within the pelitic sequence. Laterally extensive conductive zones occur commonly at the base of any one particular sedimentary unit. Where seen, these conductors are due to sulphide-facies (py-po) iron formation (Assessment report 42E03SE0007).

Jun 14, 2019 (Therese Pettigrew) - Magnetite is present in the gneiss in some places. One highly magnetic band, at the southeast end of East Shy Lake, has been traced from this point to the south end of Burslem Lake, a distance of over 2 miles. It was tested by two diamond-drillholes, near its east extremity at East Shy Lake, by Canabel Syndicate. According to James O. Stewart, who logged the core from these holes, the magnetite occurs as grains disseminated sparsely throughout garnetiferous gneiss and as aggregates of grains forming distinct layers up to 1 inch in thickness. Analyses indicated that the iron content of the rock is as much as 19 percent (weight). The thickness of this iron formation was found, in one diamond-drillhole, to be about 125 feet (Pye, 1964).
