Geology Comments

Dec 07, 2005 (R Tuomi) - The area is underlain by rocks of the Squaw Lake cycle of the Northeast Arm Assemblage (Trowell,1983). The rocks exposed in the area of the Belmore Bay no. 2 occurrence would correspond to the F2 formation. Trowell defines the F2 formation as a mafic metavolcanic sequence containing massive to pillowed flows and thin layers of hyaloclastic pillow breccia. As presently defined in Geology of Ontario,(Thurston et al. 1991), these rocks are included in the Handy Lake Assemblage, a mixed group of basaltic flows and calc-alkaline pyroclastic rocks. In the trenched areas, the exposed rocks are mainly massive to foliated dark green metabasalts with few, if any, intrusive rocks other than narrow quartz veins. Trenches have been excavated to a depth of 1 to 2 m over a strike length of 300 m. Few pillow structures are obvious, and the rocks have a schistosity which varies from north to 330 and dips steeply west. The trenches, which vary from 1 to 2 m in width, expose narrow (25 to 50 cm) rusty white quartz veins which trend 020 and have variable steep dips. Figure 4.5 shows the location and layout of the trenches. The veins pinch out and cross trenches were excavated to locate en echelon vein extensions, which are usually located within 3 to 10 m away from the original strike extension. The offsets appear to be to the east of the strike of the first vein. Two shafts were located on the vein structure. The shaft reported by Moore (1911) to be 22 feet deep is largely fallen in and the vein is not exposed. The second pit to the south, reported to be 73 feet deep, is lined by logs and has samples of quartz from the shaft on site. The grey to white quartz with pyrite and chalcopyrite mentioned in Moore (1911), was sampled and returned 1.356 ounce gold per ton (DAJ92-30), the best assay obtained in the examination. From the assays obtained (Table 4.4), the area around this shaft and the vein extensions to the south gave the best results on the property.

Mineralization Comments

Dec 07, 2005 (R Tuomi) - There is a concentration of quartz veins on this lake and a numberof reports have been written about the area. There may be some confusion of reports where data has been attributed to the wrong site.


Apr 15, 2020 (Therese Pettigrew) - Samples collected by prospector A. Best in 1991 returned 0.04 and 0.14 oz/t Au (1.37 and 4.80 g/t Au) (Assessment report 52J02NE0002).



Alteration Comments

Dec 07, 2005 (R Tuomi) - Shearing.
