Point Location Description: Transfer
Location Method: Conversion from MDI
Access Description: The Manitou Lake Property is situated in the District of Kenora, of Northwestern Ontario, approximately 45 kilometers south of the town of Dryden (Figure 1). The property is within NTS quadrangle 52F /7 and the claims are recorded on the Lower Manitou Lake claim-map (G-2683) and the Harper Lake claim map (G-2584) (Figure 2). The property lies between longitudes 93°48'W and 93°53'W and latitudes 49°20'30"N and 49°24'N. Access to the .property is via float and/or ski equipped aircraft provided by Swanair Ltd. of Dryden, Ontario. Two alternate land routes originate from Highway 512. The "Goldrock Road" is a narrow, five-mile winter road which follows along the northshore of Kabagukski (Mud) Lake and terminates at the Goldrock townsite (Upper Manitou Lake landing), approximately 9 kilometers by water, east of the property. A second land access route is provided by a 10 mile all-weather lumber road connecting the northern end of upper Manitou Lake at Jonas (Bell) Lake to Highway 512. This road has not been used in recent years and is in poor repair particularly within 1.5 miles of Jonas Lake. (Assessment File 52F/07SW U-16, St. Joe Canada Inc., Kenora Resident Geologist Office)
1904: The Queen Alexandria Mine shaft was sunk to a depth of 25 meters on a quartz vein located on the east shore of Carleton lake. Sixteen tonnes of ore grading 32.3g Au/tonne were treated. (1896-1912),(1928-1929): The Gold Rock gold camp, located at the northeast end of Manitou Lake, was developed by three mines (the Elora, (1937-38), Laurentian (1906-9) and Big Master (1902-1905) and again in (1942-1943) which produced 43,700 tonnes grading 8.6g Au/tonne. Deposit types varied from gold in quartz veins and lenses in carbnated sericite schist to quartz masses in sheared, fractured pyritized and carbonatized felsite units. 1933: Test pits were dug to evaluate three quartz veins on Frenchman Island. A chip sample from the 160 meter long "main vein" returned 4.46g Au/tonne over 0.9 meters. Minor drilling tested the middle and southeast sections of the vein without significant results reported. 1972: The whole of Frenchman Island was included in a ten (10) claim group staked by prospector James McNeil. 1980: The Ontario government sponsored a Tridem Airborne Survey over the Manitou Lake area. No significant EM anomalies were identified. Beth Canada Mining Co. carried out mapping, humus and rock sampling, magnetometer and VLF-EM surveys on frenchman Island. The humus survey outlined shear zones containing quartz-carbonate vein material. The VLF-EM and magnetics surveys also outlined several shear zones and the mag survey delineated the granodiorite porphyry intrusion. 1982: The Reliance and Frenchman Island claim groups were optioned by St. Joe Canada Inc. from M. Woitowicz of Dryden, Ontario. The following was carried out by St. Joe prior to the commencement of the period of designation for the OMEP project, line cutting, geological mapping, prospecting, magnetometer and humus geochemical surveys over the Reliance claims and Frenchman Island. Sept. 1982: Waterborne I.P. and Seismic surveys conducted by Hardy (1978) Associates Ltd. Sept., Oct., Nine diamond drill holes on Frenchman Island totalling 864m. Two diamond drill holes on the Reliance grid totalling 168m. March 1983: Detailed I. P. and magnetometer surveys on the Reliance grid completed by Claridge-LaRose Geophysics Ltd. October 1983: the initial stages of a diamond drill program on the Reliance, grid. Three holes were completed totalling 398m. Eight diamond drill holes on the Reliance Grid totalling 866 meters (2,841 ft.). One diamond drill hole on Frenchman Island "A" Zone totaling 102 meters. The diamond drilling was part of the St. Joe Canada Inc./Geddes Resources Joint Venture Agreement.

Feb 23, 2010 (D Scholtz) - The Manitou Lake Property is located in the Manitou-Stormy Lakes portion of the Archean Wabigoon Greenstone Belt of Northwestern Ontario. The property is underlain by the mafic metavolcanic sequence of the Blanchard Lake Group and intermediate pyroclastic volcanics of the overlying Upper Manitou Lake Group. The contact strikes roughly northeast, extending from the Carleton Lake quartz-monzonite stock to Reliance Bay, where the contact is offset by a north-south striking fault with left-lateral displacement in the order of 550 to 650 meters (?). On the east side of this fault, the contact between these groups cuts through the northern part of Reliance Bay towards eastern Swede Boys Island. Where the contact occurs on land, near the Carleton Lake Stock, the volcanic beds on either side appear conformable although an intervening valley may be evidence of a fault contact. The metavolcanics of the Blanchard Lake and upper Manitou Lake Groups strike roughly north-south on the southern Reliance grid but gradually change to a northeastward strike (45-65°) over much of the property. Dips are fairly consistently 60-85° southeast over the claim group. Variability is most prominent in the pillowed units. Pillowed units indicate that the top of the stratigraphic column is to the southeast. The Blanchard Lake Group underlies all of the Reliance Grid area. It is characterized by interbedded and interfingered tholeiitic and gabbroic basalt to andesitic pillowed flows and coarse-grained often porphyritic, "gabbroic" basal t flows. The pillowed flow units are commonly associated with flow breccia units, increasing in abundance to the northeast. The pillowed units and flow breccia units have been exposed to varying degrees of selective epidotization and silicification. Altered pillow cores is particularly characteristic of the pillowed mafic flow units in the Reliance North Shore area. Stratigraphic relationships between the coarse-grained (porphyritic) "gabbroic" basalt flow units and the interbedded and interfingered flow units, suggests some metamorphic overprint which may have altered some primary textural characteristics. This is further supported by the occurrence of the coarse “gabbroic” texture in some pillow cores. The upper Manitou Lake Group is characterized by dominantly fragmental pyroclastic rocks, often crystal-rich, intermediate in composition. The coarseness of the pyroclastics supports the long accepted model of a proximal vent. Rare mafic flow units, interbedded with the intermediate pyroclastics of the Upper Manitou Lake Group, are compositionally and texturally similar to mafic flows of the earlier Blanchard Lake Group, and may be derived from a more distant semi-dormant vent. The Carleton lake Stock is exposed in the southern part of the claim block. This quartz monzonitic pluton intrudes both the Blanchard Lake and upper Manitou Lake metavolcanics. The quartz monzonite is flanked by an unaltered, coarse-grained, porphyritic “gabbroic" basalt flow, of the Blanchard Lake Group, on the west. To the north, the felsic stock intrudes intermediate pyroclastics of the upper Manitou Lake Group, with many small monzonitic offshoots, quartz veining (minor pyrite, minor chalcopyrite and sphalerite locally) and minor alteration. The other significant intrusive rock on the property is the dioritic to quartz dioritic hypabyssal core, exposed on Frenchman Island and the west sides of North and South Islands.
