Nov 07, 2014 (K R Kettles) - The stratigraphic succession in the vicinity of the prospect is comprised of mafic flows at the base, overlain by thin units of black carbonaceous sediments, which are in turn overlain by argillaceous sedimentary rocks. The sedimentary rocks are overlain by a thin unit of mafic flow breccia and oxide facies iron formation. The uppermost unit is comprised of mafic flows. Rock units strike NW-SE and dip to the NE. Stratigraphic tops are to the NE. The volcanic and sedimentary rocks have been intruded by several differentiated gabbro sills. Metamorphic grade in the area has attained amphibolite facies. Mineralization is hosted in a sheared and altered ultramafic sill in iron formation. DEPOSIT DESRIPTION: Mineralization occurs as disseminated sulphide blebs near and along the basal portion of a medium to coarse grained metagabbro sill. The sulphides form 5% to 10% of the rock. Pentlandite has exsolved from pyrrhotite and with chalcopyrite it commonly rims pyrrhotite. Mineralization occurs intermittently over thicknesses up to 3 m for a distance of over 600 m.

Nov 07, 2014 (K R Kettles) - Ni assay values given by Kuryliw (1963) range from trace to 0.60% Cu and from 0.22% to 0.55% Ni. Mineralization is hosted in a sheared and altered ultramafic sill in iron formation. Mineralization occurs as disseminated sulphide blebs near and along the basal portion of a medium to coarse grained metagabbro sill. The sulphides form 5% to 10% of the rock. Pentlandite has exsolved from pyrrhotite and with chalcopyrite it commonly rims pyrrhotite. Mineralization occurs intermittently over thicknesses up to 3 m for a distance of over 600 m.
Nov 07, 2014 (A McKee) - Grab and trench samples, various samples taken around this area with assays returning at a range of 1-3 ppm Ag, and 1380-2520 ppm Ni. Medium to coarse grained 4mm-18mm 10-25% plag, no mag, Trout Bay no 1 Ni Zone.
Jul 14, 2020 (Therese Pettigrew) - Grab samples collected in 2000 returned 332-606 ppb Pd, 1710-3390 ppm Cu, 1380-2160 ppm Ni from a gabbro (Assessment report 52M01SE2013).
Dec 07, 2005 (K R Kettles) - In the vicinity of the prospect rocks have been carbonatized, silicified and contain abundant dissminated pyrite.
