Access Description: The area of the Snake Bay - Fiji Zone Project 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.

Jul 06, 2022 (Q Unknown) - The claim group is underlain by two stratigraphic groups of supracrustal rocks: the Wapageisi Lake group, and the Stormy Lake group. The metavolcanics of the Wapageisi Lake group comprise a thick sequence of pillowed, mafic volcanics of tholeiitic affinity with thin intercalated horizons of intermediate to felsic calc-alkaline flows and associated interflow sediments (chert/argillite). The sequence is capped by a thick (1 km) sequence of mafic to felsic pyroclastic breccia. Unconformably overlying the Wapageisi Lake group is the Stormy Lake group which consists of a thick (3000 m) succession of coarse polymictic and volcanic conglomerates with thin intercalated rhyolite and basaltic flow horizons. A stratigraphic column showing the age relationships of the above lithologies is found in Figure 3.

Jul 06, 2022 (Q Unknown) - Best assay: 0.06 opt Au over 42 m in ddh. 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.
