Point Location Description: Point

Location Method: Conversion from MDI

Access Description: Along the south shore of St. Paul Bay, accessible by boat in summer and snowmobile during winter. ATV and foot access is difficult but achievable from Red Lake by traveling west on HW618 turning north and traveling 2.7 km on the St Paul Bay Road, then traveling westward for approximately 1.7 km after crossing a small stream.

Exploration History

1971: Cochenour Willans hypothesized the idea of a copper-gold deposit. 1972: Cochenour Willians Gold Mines carried out ground magnetometer and HEM surveys, and drilled 2 DDH totalling 195.4 m. 1973: A. Kostynuk carried out sampling and drilled 1 DDH totalling 32 m. 1981: Selco Mining Corp. drilled 1 DDH totalling 122.8 m. 1990: Aur Resources optioned the property from D. Meunier. 1991: Aur Resources carried out linecutting, ground magnetometer and HEM surveys, and drilled 3 DDH totalling 677.6 m. 2000: D. Meunier carried out trenching, mapping, and a VLF-EM survey. 2002: Wolfden Resources Inc. optioned the property from D. Meunier and Freewest Resources Canada and carried out a detailed mag survey and soil sampling. 2002: Teck optioned the property from Wolfden Resources and drilled 5 holes totalling 1125.3 m after acquiring 51% interest in the property. Teck identified hydrothermal alteration zones defined by magnetite destruction cross-cutting mafic-ultramafic volcanic contact. 2009: Rainbow Resources Inc. optioned the property. 2010: Rainbow Resources carried out magnetic, pole-dipole IP and resistivity, bathymetry, and moving loop TDEM surveys. 2011: Rainbow Resources drilled 9 DDH totalling 2001 m.

Lithology

Lithology Comments

Apr 14, 2020 (Samuel Lewis) - Mapping by Riley, R.A. in 1975 identified this MDI location as intermediate volcanics characterised by tuff, lapilli-tuff, tuff-breccia and breccia, slivered between metamorphosed mafic to ultramafic intrusive rocks characterised by serpentinite, serpentinite pyroxenite and peridotite. Reviewing diamond drill logs and assessment files within this area suggests the intermediate volcanic rocks are a minor component to the more ubiquitous mafic to ultramafic rocks. The St. Paul Bay was identified as a deformation corridor by Aur Resources where hydrothermal alteration via magnetite destruction and silicification, to some extent may have precipitated the Ni, Cu, Au, Ag, As, mineralization seen in drill core. This MDI located on a southeast northwest striking high magnetic linear structure that extends from the Killala-Baird Batholith, 8.8 km northwest.

Mineralization

Mineralization Comments

Apr 14, 2020 (Therese Pettigrew) - Aur Resources encountered a 55 foot wide (16.76 m) talc-chlorite schist deformation zone including an 8 foot (2.43 m) silicified section averaging 0.024 oz/t Au (0.82 g/t Au), including 0.044 oz/t Au over 3 feet (1.5 g/t Au over 0.91 m) (Assessment report 52N04SW0007). DDH SPR10-3A returned 1.3 g/t Au over 2.1 m from the contact between a mafic volcanic and a peridotite. DDH SPR10-06 returned 1.14 g/t Au over 0.5 m from an interval of silica alteration within a mafic metavolcanic. DDH SPR10-08 returned 1.15 g/t Au over 1 m from mineralized quartz-carbonate stringers within a granodiorite (Assessment report 20000008946). DDH SPB-03-1 returned up to 9.198 ppm Au and 1529 ppm Cu over 0.3 m from a gabbro with disseminated pyrite, chalcopyrite, and molybdenum. DDH SPB-03-3 returned 0.915 g/t Au and 204 ppm Zn over 0.2 m a zone of disseminated and stringer fine arsenopyrite in a mafic metavolcanics, 4.845 g/t Au over 0.4 m a quartz vein with arsenopyrite in a felsic tuff, up to 11,420 ppm Zn over 0.3 m from a sphalerite vein with arsenopyrite in a felsic metavolcanics, 7659 ppm Zn over 1.2 m from a felsic tuff containing 5-7% pyrite and pyrrhotite, and 3.179 g/t Au over 0.7 m from a massive silicified mafic metavolcanic (Assessment report 52N04SW2069).

Apr 14, 2020 (Samuel Lewis) - Mineralization containing 20% pyrrhotite, and minor pyrite and chalcopyrite, returning assay results of 0.41% Cu with trace Au, Ag, were collected by Mr. Riley. Diamond drill holes by Teck discovered 9.2 g/t Au over 0.3 m and other anomalous gold enrichments of 1.1 g/t Au over 3.1 m with elevated As within sheared mafic volcanic rocks at the contact of the mafic-ultramafic rocks.
