Jun 02, 2017 (A Wilson) - The deposit is interpreted to be a mantle-derived ultramafic intrusion emplaced along the margin of a granodiorite pluton. The deposit is overlain by approximately 8 m of dolomitic limestone and sandstone. The deposit is a sub-vertically dipping body of massive magmatic sulphide in a pipe-like form approximately 200 m long, up to several tens of metres thick and at least 1200 m deep. It strikes northeast and occupies the northwestern margin of a vertically inclined serpentinized peridotite dyke that is present in subcrop. The present plunge of the keel of the dyke at the level of the deposit is about 70° along an azimuth of N180° from surface to a depth of 300 m.

Jun 02, 2017 (A Wilson) - Two styles of mineralization have been found in the deposit: massive and net-textured. Significant assays from discovery drill hole DDH NOT-07-01 are 1.84% Ni, 1.53% Cu, 1.14 g/t Pt, 3.49 g/t Pd, 0.13 g/t Au, and 4.80 g/t Ag over 36 m (from 56.0 to 92.0 m). A 4.1 m section of core from NOT-07-05 averaged 3.2% Cu, 3.62% Ni, 30.2 g/t Pt, 15.95 g/t Pd, 3.3 g/t Au, 8.1 g/t Ag, 0.84 g/t Rh, 0.15 g/t Os, 0.21g/t Ir and 0.42 g/t Ru. The massive sulphides tend to be coarse-grained with grain sizes up to 1 cm. Sometimes the pentlandite is aligned along microfractures. Medium- to very fine-grained massive sulphide veins are commonly found. These veins are often rich in silicate inclusions. The sulphides are described as massive, net-textured and disseminated. In 2009 two lenses of mixed disseminated to massive sulphides were intersected below the Eagle One Deposit in drill hole NOT-09-49. These lenses are located vertically below the deposit.
Jun 02, 2017 (Therese Pettigrew) - Other significant assays from NOT-07-05 are 4.10% Ni, 2.2% Cu, 2.09 g/t Pt, 7.13 g/t Pd, 0.42 g/t Au, and 6.30 g/t Ag over a 117.4 m length from 7.0 to 124.4 m, including 8.65% Ni, 10.90% Cu, 40.79 g/t Pt, 14.57 g/t Pd, 9.39 g/t Au, and 8.70 g/t Ag over a 3 m interval from 112.6-115.6 m (Burgess et al., 2012). Eagle’s Nest is a sub-vertically dipping body of massive magmatic sulphides (MMS) in the form of a flattened pipe approximately 200 m long and 60 m thick, and currently defined vertically to 1,650 m. The deposit remains open along strike and occupies the northwestern margin of a vertically-inclined serpentinized peridotite dyke that is present in subcrop over a north-south strike length of about 500 m with a maximum width of about 75 m. The massive sulphides within the top 250 m are confined to a volume occupying the northwestern tip of this body, and are bordered to the southeast by a thicker zone of net-textured sulphide hosted by serpentinized peridotitic cumulates. Below 250 m, the massive sulphides can be found throughout the mineralization and, in some cases, into the surrounding granodiorite. The dyke is open at the north and south ends, and plunges very steeply to the south or vertically. The exact attitude of the sulphide-filled keel at the northern tip of the dyke is impossible to state because of the irregularity of the contact. Although a considerable amount of local deformation is evident around the contacts, particularly where they are occupied by massive sulphide, the body appears to be essentially still in place and not significantly deformed. The host rock of the Eagle’s Nest ultramafic dyke is granodiorite that apparently post-dates the overlying ROF iron formation but clearly predates the intrusion of the peridotite. Because the host rocks are magnetically inert felsic rocks with little or no structural fabric and relatively low density, the intrusion is easy to recognize on magnetometer or gravimetric survey data. Inspection of the magnetometer survey results indicates that there is a second dyke parallel to and east of the Eagle’s Nest dyke, but offset en echelon to the southeast. This has been called the Eastern dyke. A third, the Southern dyke, occurs south of both of these, along strike with the Eagle’s Nest dyke (Burgess et al., 2012).
