Point Location Description: Assessment report 52E10SW8557

Location Method: Data Compilation

Access Description: Access to the property is via the Trans Canada Highway west from Kenora, 37.5 km to Rush Lake Road which is followed south 5.9 km to Clytie Bay road which is then followed for 13.2 km to the north shore of Shoal Lake. From here the property is reached by a 4 km boat trip across Shoal Lake in the summer. A winter road that winds around the east shore of Shoal lake can be used after freeze up.



Exploration History

1974: Imperial Oil Ltd. conducted EM and magnetometer surveys. 1985: Kenora Prospectors and Miners (KPM) carried out trenching and sampling. 1985: St. Joe Canada Inc. optioned the property. 1987-88: Bond Gold Canada Ltd. (formerly St. Joe Canada) carried out geological mapping, sampling, geophysical surveys, and drilled 127 DDH totaling 27,288 m. 2003: Amador drilled 11 DDH totaling 3205 m. 2004: Amador drilled 35 DDH totaling 10,011 m. 2008: Hays Lake Gold Inc. optioned the property from KPM. 2009: Everton Resources acquired Hays Lake Gold. 2012: Everton’s option agreement lapsed. 2013: Cougar Metals optioned the property from Kenora Prospectors & Miners. 2015: Cougar Metals commenced legal action against KPM with regard to alleged breaches of certain representations and warranties made by KPM under the option agreement. 2016: arbitrator awarded costs to Cougar.

Mineralization Comments

Jan 13, 2020 (Therese Pettigrew) - In 1985, Kenora Prospectors and Miners encountered gold mineralization from surface trenching and sampling on the mainland east of and along strike from the Cedar Island Mine. The shear was trenched over a strike length of 350 m and returned gold values up to 20.9 g/t Au over 1.2 m along a 9.29 m strike length and 11.3 g/t Au over 2.16 m along a 7.9 m strike length. Drilling indicates that the Cedar Island Mainland shear zone is characterized by numerous quartz veins, and in stringers consisting of a continuous, predictable “vein” called the Main Vein. It is flanked up dip and down dip by a series of multiple stringers/veins defined as Hangingwall Veins 1, 2 and 3 and Footwall Veins 1 and 2. The veins are structurally controlled, recognized as fracture infill, crack and seal and breccia veins, related to the late stage emplacement of the Canoe Lake stock. The veins occupy a reactivated fault zone that has undergone multiple episodes of shearing and intrusion. The veins trend 125 to 140 degrees, dip subvertically to 65 degrees southwest; dips tend to flatten with depth and to the east with a few exceptions. The veins have been traced by drilling for approximately 1.7 km. They show a degree of sinuosity along strike and down dip and show some dextral offset. Felsic intrusives are spatially associated with the veins and are a strong component of the structural zone(s). The Main Vein and its associated Hangingwall and Footwall Veins generally have a poorly developed alteration envelope. The individual veins do not normally exceed 0.90 m in width but the zones on occasion may attain 2.5-3.0 m in width. Silicified or quartz veined sections generally contain calcite, mafic wallrock inclusions, chloritized partings and sulphides. Two generations of quartz are present: a) grey to white quartz, and b) glassy, smokey grey-blue quartz. The latter contains the strongest sulphide concentration and returns the best gold values. At least two generations of sulphide mineralization are present. The predominant sulphide is fine-grained pyrite followed to a much lesser extent by pyrrhotite with only the occasional appearance of sphalerite and chalcopyrite. The Hangingwall and Footwall Veins are secondary structures to the Main Vein and tend to be narrow, stringered quartz-calcite veins. They are separated from the Main Vein and each other from between 5 m and 25-30 m and tend to separate with depth. Massive sulphide (pyrrhotite, pyrite, chalcopyrite) horizons (up to 10 m wide) occur above and below the Main Vein and in hole K87-102 cross-cut the Main Vein. These horizons are not definitely correlatable along strike or down dip. The sulphide horizons have returned 10.97 g/t Au over 1.50 m and 13.70 g/t Au over 1.25 m in hole K87-102. The highest gold values were intersected in K88- 124 in the Main Zone, which returned 3.12 g/t Au over 1.22m at a vertical depth of 176 m. The best Hangingwall One Vein gold values were intersected in holes K87-110 and K88-114. K88-114 intersected the Hangingwall One Vein which returned 4.1 g/t Au over 1.17 m at a vertical depth of 328 m. The best mineralization encountered in the Hangingwall Two Vein was found in holes K88-116 and K88-122. K88- 122 returned 15.08 g/t Au across 0.40 m at a vertical depth of 175 m (Assessment report 52E10SW8557).
