Location Method: Data Compilation

Access Description: The area of the Snake Bay - Main Katisha 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.

Geology Comments

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.

Mineralization

Mineralization Comments

Jan 05, 2023 (Therese Pettigrew) - The most significant mineralized zones are hosted by numerous, 1 to 15 m wide, north-trending faults and northwest-trending shear zones in a magnetite-bearing, composite gabbro sill and magnetite-bearing mafic metavolcanic flows. The shear zones have been sericitized, and pervasively and intensely iron carbonatized, and host colloformed textured carbonate veins up to 5 m in width. The carbonate veins contain angular xenoliths of wallrock and minor disseminated pyrite. The carbonate alteration is postdated by pervasive silicification and quartz veining, associated with abundant disseminated pyrite, arsenopyrite and gold. The silicified zones are narrow, pod-shaped, and concentrated in flexures and wider sections of the shear zones. A second phase of silicification consisting of barren quartz veins overprints the earlier gold-bearing phase of silicification. Alteration terminates abruptly at the boundaries of the shear zones (Blackburn et al., 1989). Gold, where detected, is associated with discreet silicified lenses ranging in width from a few centimeters to 2 or 3 meters. The silicification is accompanied by ankerite, sericite, chlorite, pyrite and arsenopyrite. These lenses are localized along shear or fault zones ranging from 50 to 350 meters in length, although the actual strike length of each of the zones has not been determined due to overburden or swamp cover. The Main Katisha Zone lies within mafic to intermediate volcanic rocks near the contact with the gabbroic sill. At the eastern end of this zone, it appears to change directions from a 120 degree trend to nearly north-south, and may lie within the gabbroic sill (Assessment report 20000008225). Sampling by Ashley Gold in 2022 returned up to 1.26 g/t Au from a grab sample and 52.80 g/t Au over 0.4 m from a channel sample (Ashley Gold Nov 28, 2022 press release).

Jul 06, 2022 (Q Unknown) - Best assay: 0.25 opt Au over 1.55 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 (Figs. 4, 5) 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.
