Point Location Description: Transfer

Location Method: Conversion from MDI

Access Description: The area of the Snake Bay - Fringe Zone Project and is located some 55 km southeast of Dryden, Ontario. Access to the Snake Bay property claim group is via the Snake Bay Road, an all weather gravel road which leads south from Highway 17. This road runs through the middle of the claim group, and a number of logging roads lead off this road providing additional access to the region. The area contains numerous lakes interconnected by short portages or creeks. Virtually all the map area is within a kilometre of a road or navigable lake which greatly facilitates exploration work.

Mineralization Comments

Jul 06, 2022 (Q Unknown) - Best assay: 7.0 g/t Au. The most significant gold mineralization on the Snake property is hosted by shear zones cutting oxide-bearing gabbro. The shear zones are part of a conjugate set trending 180°/90°and 120° /40° S respectively throughout the property. To date seven main mineralized zones have been discovered by EMC, of which five have been drilled. The shear zones range from 1.0 to 15.0 metres in width and are marked by an intense foliation developed parallel to the trend of the zones. These zones are the focal point for hydrothermal alteration and associated veining, generally consisting of an early carbonate (Fe-carbonate + minor pyrite) generation overprinted by a quartz stockwork vein set. The early carbonate veins are typically colliform textured, up to 5.0 metres in width, and have formed parallel to, and in the centre of, the shear zones. Consanguineous with the carbonate veining, carbonatized haloes in the wallrock developed up to 15.0 metres away from the zones. In the wider shear zones, thin (2m), lamprophyre dykes are found intruded along the centre of the veins. No significant Au values (i.e. 2.0 g/t) are associated with this period of veining. Sporadically developed zones of quartz-stockwork veining and associated silicification overprint the carbonate veining. These zones are typically small (2m) and anastomosing and are formed at the widest portions or bends in the shear zones. Sulphide mineralization (py, aspy), locally present in amounts up to 40% is found within the silicified zones. Significant gold values (i.e. 2 to 10 g/t) are intimately associated with this sulphide mineralization. Three Au-bearing zones were cleared, sampled and mapped during the 1984 field season. Two of these zones occur in the upper gabbro sill and the third in the lower gabbro sill. The Old Timer and Twilight Zones (Maps 3 and 5) occur within and adjacent to the "East Fault Zone”. Fringe Zone: Only one gold-bearing zone was discovered in the lower gabbro sill body. A thin, 3 wide north easterly trending tectonized zone is located near the southeastern corner of the claim group (claim #731140). The zone is composed of a weakly to moderately sericitized/carbonatized and foliated core (0.5 m wide) with 1 to 2 metre wide pyritized haloes (pyrite replacing magnetite) formed in a weakly foliated gabbro (in hangingwall and footwall). Grab and channel samples from this zone contain from nil to 7.0 g/t Au. No further exploration of this zone is recommended due to the absence of significant assays over mineable widths. A possible strike extension of this zone is found on claim #732088. This zone has a strike length of 200 m and attitude of 130°/80° (identical to the Fringe Zone). The zone is composed of a 0.5 to 2.0 metre wide silicified zone, containing locally abundant pyrite and fuchsite. Carbonate alteration is absent and no gold-values were found in grab samples. If this silicified zone is the northwestern strike extension of the Fringe Zone, it has been offset approximately 150 m on the left-hand fault.
