Iris Lake Regional Geology
The Iris Lake Property is located near the west end of the Archean Shebandowan Greenstone Belt (SGB) of the Wawa Subprovince (Figure 4). The Subprovince is an aggregation of Archean greenstone belts and granitoid plutons, which hosts several world-class gold, base metal and iron deposits in diverse geological settings. It is home to some of the largest shear-hosted lode gold (e.g., Hemlo gold mines), volcanogenic massive sulphide (e.g., former Geco and Winston Lake zinc mines) and mafic intrusion hosted Ni-Cu-PGM (e.g., former Shebandowan mine) deposits in Canada. The Wawa Subprovince extends for approximately 850 km from the Kapuskasing Structural Zone in northeastern Ontario to west-southwest into the Minnesota River Valley area in North Dakota, where the Subprovince truncated by the Proterozoic Trans-Hudson Orogen.

1. It is not known if these drill hole intervals represent true widths and are therefore being treated as core length intersections.
2. A Qualified Person has not done sufficient work to verify the historical drill core sampling and reported drill core intercepts reported herein.

Iris Lake Zone (Alteration)
The Iris Zone is hosted in a broad southwest striking and steeply dipping deformation zone. This zone is comprised of variably schistose to sheared alternating felsic to mafic metavolcanics commonly displaying silica, chlorite, sericite, albite, iron-carbonate, magnetite, potassium and hematite alteration. From an economic point of view, the most important rocks in this area are the sheared mafic metavolcanics with strong silica, chlorite, hematite and carbonate alteration with trace to up to 5% disseminated and stringer pyrite (+ chalcopyrite).
