Dec 07, 2005 (K R Kettles) - The Follansbee property is underlain by felsic volcanics, mafic volcanics and sediments. Mafic volcanics occur in the northern portion of the property, and consists of pillowed flows. The felsic volcanics outcrop in the central portion of the property. Clastic and chemical sedimentary rocks underlie the southern portion of the property. All of the units strike approximately east-west and dip nearly vertically.

Mar 15, 2012 (K R Kettles) - A thick unit of iron formation is reported to contain gold. 2009:The better gold grades tended to be associated with concentrations of Fe-sulphides including pyrrhotite, pyrite, and +/- arsenopryrite particularly within brecciated sulphide/oxide facies iron formations (B1 zone) and sulphide fragments within the conglomerates (F1 zone) to the north. Assays ranged up to and including 5.4 g/t Au over 5 m, 21.8 g/t over 3m.
Aug 31, 2022 (Q Unknown) - 1946: 2 DDHs in if, best section at 15 ft, assays 0.04 opt Au/6.5 ft (#F-4). 1978: new drilling, all assays nil (4 DDHs). 2003: DDH of 5.4 g/t over 2.8 m from 815.6 m. 2005: Of the 37 cuts totals ranged from 1.1 g/t Au to 6.38 g/t Au.
Dec 07, 2005 (K R Kettles) - The country rocks have been silicified and carbonatized.
