The East dyke is an ultramafic body located 150m southeast of Eagle’s Nest. It straddles Noront’s lease boundary with claims held by Fancamp Exploration (figure 1). The dyke forms part of the Double Eagle Intrusive complex (DEIC) and is believed to be co-eval with Eagle’s Nest. The East dyke strikes north-south for ~800m before it is truncated against the Triple-J fault (aka Frank’s fault) along the south. At its widest the dyke measures 300m and has been modelled to >1km depth. Towards the north, the dyke pinches to <40m width. It is in the northern section of the East Dyke that anomalous to low-grade Ni-Cu-PGEs have been intersected. A highlight of these intersections is presented in the table below.
In 2011, Noront released a preliminary resource estimate for the East Zone, which is situated in the northern portion of the East dyke. The East Zone contains an Inferred resource of 1.6Mt at 0.31% Ni, 0.09% Cu, 0.12g/t Pt, 0.45g/t Pd and 0.04g/t Au1.

Although Ni-Cu mineralization intersected in the East dyke to date is low grade the area contains several wide intervals of low to moderate PGE grades. Further work at depth is warranted given the proximity to Eagle’s Nest, similarity of magma type and presence of high tenor Ni-Cu-PGE mineralization.
