Point Location Description: Center of Cherry Hill trench from NI 43-101 report

Location Method: Conversion from MDI

Access Description: The property is accessed by following Highway 11/17 west of the City of Thunder Bay to Highway 11 at Nipigon, Ontario. One then travels north on Highway 11 for approximately 120 km turning north onto the Kinghorn Road, 7km east of Jellicoe. One then travels approximately 125 km north where the Kinghorn Road intersects the southern portion of the Marshall Lake property. Further access from this point is by ATV or on foot. The property is about 45 km from Aroland First Nations Reserve. Access from the reserve is down the Ogoki road about 55 km (45 km by air) and then by boat on Marshall Lake.



Exploration History

1954: Teck Corp. discovered a high-grade Cu/Zn showing to the south of Gripp Lake. 1955: Teck Corp. carried out mag & EM surveys followed by a 20-hole DDH program. Claims were allowed to lapse because the demand for base metals had declined. 1960-2: Jacobus Mining Corp. Ltd. staked claims. 1961: Teck Corp. carried out a 12-hole DDH program. 1962: Jacobus carried out a 64 DDH program totalling 3306 m and conducted EM and mag surveys. Min-Ore Mines Ltd. carried out an 8-hole DDH program totalling 382 m. 1965: Marshall Lake Mines Ltd. acquired the property from Jacobus and Min-Ore and carried out a 5-hole DDH program. 1968: Kendon Copper Mines carried out a DDH program and an IP survey. 1969: NWT Copper Mines Ltd. acquired the property from Kendon Copper and carried out a 13-hole DDH program, EM, IP and magnetometer surveys, trenching and prospecting, and a property report. 1970: feasibility study by A. S. Bayne. 1971: Teck Corp. did EM, mag and self-potential surveys. 1974: Giant Gripp Mines Inc. carried out an EM survey. 1976: St. Josephs Exploration completed a mapping program as well as a magnetic survey and soil sampling. 1978: Imperial Oil completed a DDH program. 1981: Corporation Falconbridge Copper carried out a ground mag survey, VLF-EM and soil geochemistry. 1983: Corporation Falconbridge Copper carried out a 3-hole DDH. 1992: Giant Gripp Mines Inc. did a DDH program. 1994: Challenger Minerals carried out an EM survey and a DDH program. 1995: Consolidated Abitibi did airborne EM & mag surveys and a 5-hole DDH program. 1996: NWT Copper Mines Ltd. did a DDH program. 2000: geological mapping was done over the area by G. Stott for the OGS. 2006-9: East West Resources and Eyeconomy acquired the Marshall Lake property from NWT Copper and began mapping, prospecting, trenching, 58-hole DDH program, IP, Mag and VTEM surveys. 2006-7: East West conducted trenching on the Teck Hill showing. 2007: East West conducted a VTEM airborne survey over the entire property. 2007-8: East West conducted ground IP surveys. 2008: 10 DDH were drilled to test the depth extension of the Gazooma (3 DDH), Teck Hill (4 DDH) and North Gazooma (3 DDH) areas. Eyeconony changed their name to Marshall Lake Mining. 2009: Rainy Mountain Capital Corp. purchased East West. 2010: Rainy Mountain changed its name to Rainy Mountain Royalty Corp. White Tiger Mining Corp. took an option to earn up to 50% of the interest in the Marshall Lake property from Rainy Mountain and drilled on the Gazooma Zone. 2014: White Tiger changed its name to Copper Lake Resources Ltd. and holds 25% interest in the project.

Mineralization Comments

May 08, 2015 (Therese Pettigrew) - A sericitized shear zone runs to the NW from the SE end of the trench and contains samples JL-07-001, -004 to -007. Mineralization is in the form of disseminated to patches of fine grained pyrite sulphides and minor chalcopyrite. Within the sericitized shear zone, samples JL-07-005, -006 and -007 contain 5690 ppm Cu, 0.591 ppm Au and 51.7 ppm Ag in -005; 8040 ppm Cu, 0.576 ppm Au and 26.7 ppm Ag in -006 and 4830 ppm Cu and 0.235 ppm Au in -007. Sample JL-07-006 along with mineralization contains 167 ppm As. Sample JL-07-002 at the south part of the zone contains 1850 ppm Cu along with 3050 ppm Zn. Sample JL-07-006 also contains 11.35% Fe and 9.52% S. Along with the 4830 ppm Cu, sample JL-007 contains 7240 ppm Zn, 917 ppm Pb and 9.52% S. Sample JL-07-008 in another zone contains 8520 ppm Cu, 755 ppm Zn, 0.310 ppm Au and 27.5 ppm Ag. In a quartz and carbonate-rich shear zone to the north, sample JL-07-010 contains 6100 ppm Cu and 0.183 ppm Au. Other samples in sheared volcanics with assays are JL-07-012, -013 and -016 with 2110 ppm Cu in -012; 3740 ppm Cu and 0.139 ppm Au in -013; and 3280 ppm Cu, 0.184 ppm Au and 50.1 ppm Ag in -016. RSM-06-020 is another mineralized sample in the trench with 4.47% Cu and 92.4 ppm Ag. Another mineralized sample in the trench, NP-07-028, taken near JL-07-001; contains 3.61% Cu, 4810 ppm Zn, 1.31 ppm Au and 123 ppm Ag. DDH NWT-07-01 assays reported include a zone of average 2527 ppm copper over 28.7 m from 20-48.7 m including an intercept of 1.08% Cu at 26 m and an intercept of 1.21% Cu at 47.1 m; a zone of average 4133 ppm Cu over 8.5 m from 79.5-88 m; and an intercept of 1.56% Cu and 35.4 g/t Ag at 121.2 m (Neilsen et al., 2010).
