Oct 21, 2014 (Mark Puumala) - The following geological description of the Bluff Showing is excerpted from Hart (2000 OFR6037). The rocks currently exposed in the trenches resemble the intensely sheared and iron carbonate altered mafic metavolcanic rocks observed in the eastern trench of the Point showing (see “Point”). The rocks are dark green to medium brown, intensely sheared and altered containing disseminated sulphides or lenses of up to 5% sulphide. The sulphide is mainly pyrite with lesser pyrrhotite (Photo 12). A number of white quartz veins containing variable amounts of iron carbonate, 1 to 2% sulphide and generally a significant amount of green mica are most prominent in the north end of the two trenches closest to the lake shore. A single sample of the quartz veining with green mica returned no detectable gold (sample 2242; Table 3). The discrepancy between the grab samples and the detailed sampling by a number of workers (e.g. Junnila, 1989; Stares, 1997a, b) indicates that the controls on gold mineralization in this area are not well understood. A detailed sampling program with short sample lengths, the use of a larger assay weight, and/or metallic separates would aid in the identification of the features control the gold mineralization.
