Point Location Description: Centre of North Gazooma 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, 7 km 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 Gazooma Zone. 2007: East West conducted a VTEM airborne survey over the entire property and a drill program on the Gazooma Zone. 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.

Geology Comments

May 08, 2015 (Therese Pettigrew) - The Marshall Lake property area comprises of a sequence of Neo-Archean calcalkaline metamorphic-volcanic rocks and volcanogenically-derived clastic and chemically-derived metasedimentary rocks within the Marshall Lake Series, an accumulation of felsic to intermediate bimodal rocks over 9000 m thick. The property is situated on the southern limb of a regional antiformal fold at the top of the Marshall Lake Series and is a deformed acidic metavolcanic complex. It is comprised of a large dacitic volcanic pile located on the northern margin of the Onaman-Tashota greenstone belt within the eastern portion of the Wabigoon Subprovince. The geology of the area is dated at 2739 Ma (Nielsen et al., 2010).
