Exploration and Mining History

2000-2006: Aurora Platinum Corporation completed several geophysical surveys, mapping, and sampling. 2003-2010: Northern Superior Resources (then Northern Superior Diamonds) became involved with the TPK project while conducting till sampling on behalf of Aurora Platinum and while prospecting for kimberlite indicator minerals. The till sampling program produced gold grain-in-till anomalies particularly around Canopener Lake. 2005: Aurora was purchased by FNX Mining Company Inc. and Aurora’s interest in the remaining Rowlandson Lake and Canopener Lake claims were sold to Lake Shore Gold. Northern Superior and Lake Shore then formed a 50:50 joint venture agreement. 2007-2008: A total of 1028 till samples were collected to investigate the emerging gold-grains-in-till anomaly. The TPK property was expanded to cover both the 7 x 7 km head of the main anomaly. 64 diamond drill holes were completed over three separate programs. 2009: Northern Superior conducted a series of airborne electromagnetic and magnetic surveys. 2010: NSR conducted two separate phases of reconnaissance-scale reverse circulation drilling program. Entered into a JV with Rainy River Resources. 2011: RRR became the operator and completed 23 drill holes. RRR terminated the JV.

Mineral Deposit Lithology

Lithology Comments

09/12/2019 (T Pettigrew) - This area is underlain by fine-grained dark green mafic volcanics cut by folded grey siliceous dacite dykes and salmon pink weathering quartz-feldspar porphyry (contains 1-2% 2-3 mm glassy quartz eyes, likely dacite). The mafic volcanics are locally foliated and cut by <1 cm wide foliation parallel quartz-sulphide veinlets trending 079/90. Late quartz-filled tension gashes cut the volcanics at 162/80W. The feldspar porphyry is locally sheared and weakly iron oxide stained on weathered surfaces. On fresh surfaces, the iron oxide stained quartz-feldspar porphyry was found to contain trace to 15% sulphides. Iron oxide stained quartz-feldspar porphyry with 10% well formed, medium-grained pyrite cubes and 5% fine-grained arsenopyrite needles yielded 615 ppb Au, with elevated concentrations of As, Cd, Pb, Sb and Zn (sample 174599). Samples of east-west (260/90) trending quartz-sulphide veinlets and actinolite altered mafic volcanics with 2-3% pyrite-chalcopyrite from this zone were also found to contain anomalous concentrations of Au and other elements (samples 173525 and 173524, 155 and 160 ppb Au, respectively) (Assessment report 53J08NW2001).

Mineralization

Mineralization Comments

08/04/2016 (A Tims) - Mineralization was emplaced principally within or proximal to an originally sub vertical to steeply S-dipping series of high-angle reverse faults, with subordinate shallower- (S-) dipping shears (R-style linking shears). Deformation was dominantly N-S compression, related to significant transpressive NW- to E-W shear along the regional-scale Stull FZ to the west and south.

08/03/2010 (N Bennett) - From 83.8m to 84.28m = 1.335 g/t Au associated with shear containing qtz, biotite alteration. From 162.10m to 163.49m = 0.511 g/t Au. Associated next to ironstone in an intermediate schist. From 163.49m to 164.88m = 0.812 g/t Au. Associated next to ironstone in an intermediate schist. From 164.88m to 165.28m = 0.626 g/t Au. Associated next to ironstone in an intermediate schist.

08/16/2018 (T Pettigrew) - An approximately 50 by 100 m zone of intermittent outcrop some 1.2 km north of Canopener Lake returned elevated concentrations of As (618 ppm), Co (290 ppm), Mo (35 ppm), Pb (60 ppm) and Zn (738 ppm) from dacitic volcanics (sample 166874). Mapping during 2001 located chalcopyrite in quartz veins and arsenopyrite needles in a narrow shear which returned 0.6 g/t Au Assessment report 53J08NW2001). DDH CAN-07-03: Sample 263231 from 89.33 to 89.45 m assayed 2062 ppb Au. Sample 263238 from 127.20 to 128.00 m assayed 641 ppb Au. Four holes were drilled in 2008 by Lakeshore Gold to follow up on the 2007 drill program. A number of anomalous intervals were intersected generally hosted by intrusive rock. DDH CAN08-027 intersected 3 gold mineralized intervals: a sheared, fine-grained, quartz flooded, biotite- and sericite-altered diorite dyke hosting trace fine-grained pyrite that returned 0.64 gpt Au over 1.34 m; a sheared, intensely chloritized and biotite-altered gabbro to hornblende diorite that returned an average of 0.68 gpt Au over 2.73 m including 3.44 gpt Au over 0.34 m; a sample of weakly sheared gabbro containing trace fine-grained pyrite and arsenopyrite returned 0.51 gpt Au over 0.5 m. Collared 200 m to the north, CAN08-028 intersected several intervals of anomalous mineralization hosted by silicified, biotite-altered intervals of sheared granite containing trace to 1% fine-grained disseminated to fracture-filling pyrite. The best intervals are an averaged interval of 0.44 gpt Au over 1.95 m, including 0.55 gpt Au over 0.95 m and 1.11 gpt Au over 1.5 m. The averaged interval is hosted by a granite containing 3-5% disseminated fine-grained magnetite and occasional 20 cm bands of 5-10% magnetite. Hole CAN08-031 intersected a sheared and intensely sericitized, chloritized, and silicified plagioclase porphyritic diorite that returned 1.34 gpt Au over 0.48 m. A similar sheared and altered interval of plagioclase porphyritic diorite to granodiorite containing trace to 1% disseminated arsenopyrite averaged 0.66 gpt Au over 3.18 m. This second interval is located between two of three closely spaced horizons containing up to 60% magnetite, with up to 10% fine-grained, disseminated pyrite and trace to 1% fine-grained arsenopyrite that returned only anomalous gold values. The anomalous gold intersection in CAN07-003 was hosted by a gabbro containing disseminated sulphide and magnetite, and also returned 8,695 ppm Cu. About 350 m to the north, drillhole CAN07-027 intersected an interval that returned 8,650 ppm Cu over 0.37 m, Drill hole CAN09-029, collared about 380 m east of CAN08-027, intersected 37,900 ppm Cu over 0.30 m (3.79 % Cu). These intersections are associated with gabbro intrusions that can be trace by the airborne magnetic response east to the area of the Copper Point showing in the TPK area, a distance of about 10 km (Hart and Boucher, 2010).
