Apr 19, 2017 (C Ravnaas) - The Bag Lake claims are underlain by Snake Bay volcanics that consist heavily of pillowed basalts with irregular bodies of gabbro to pyroxenite that appear intrusive in origin. The pillows are locally sheared with associated carbonate alteration and weak quartz veining. The pillows generally show good preservation over most of the claim group. Felsic intrusive dikes commonly cut the volcanics in a north-northwest fashion carrying anomalous gold values. Gold occurrences on the claim group are hosted within different environments: Knapp occurrence within sheared felsic intrusives, the Jenson- Johnson within a silicified gabbro, Bag South occurrence is quartz vein hosted within a diorite plug and the Cliff Zone is shear quartz/carbonate hosted. The mineralization to date on the claims tend to have orientations ranging from 120 to 140 degrees which tends to follow the regional fabric of the area (Kenora AF 52F05SW, QQQQ-17, 2.57190, Metals Creek Resources, pg.5)

Sep 18, 2017 (C Ravnaas) - Trench JJTR3 was not channeled but had 8 grab samples taken from it averaging 3.67 g/t gold. The actual mineralized horizon yielded 5.94 g/t gold over 1.2 m in trench JJTR2. Including the wallrock sampling, trench JJTR2 returned 3.79 g/t gold over 2.0 m. Trench JJTR1 returned 0.13 g/t gold over 2.0 m and 0.42 g/t gold over 3.25 m (Kenora AF 52F05SW, QQQQ-17, 2.57190, Metals Creek Resources, pg.16). Grab sample SAS16-15 described as ‘mineralized zone, highly siliceous, 5-7% pyrite with quartz veining’ ran 10.6 g/t Au (Kenora AF 52F05SW, QQQQ-17, 2.57190, Metals Creek Resources, Appendix I). Speculative Tonnage: 22,500 T @ 0.25 opt Au (Neilson and Bray, 1981).
Sep 18, 2017 (Therese Pettigrew) - Grab samples taken before the 1961 drill program assayed from trace to 0.5 opt Au (15.6 gpt Au), and the highest assay from the drill program was 0.23 opt Au over 2.5 ft (7.2 gpt Au over 0.76 m) (AFRI 2.57095). The best assays from the 1988 drill program include 19.55 g/t Au from 14.69-14.90 m and 34.90 g/t Au from 57.03-57.28 m in DDH BAG-10 (AFRI 52F05SE0003). Metals Creek Resources obtained assays up to 28.66 gpt Au during their 2016 sampling program along the historic trench. The surface expression of the zone has been traced for approximately 87 m (AFRI 2.57095). The showing is described as gold-bearing pyrite in a shear zone 4-8 ft (1.2-2.4 m) wide in mafic metavolcanics (Beard and Garratt, 1976).
