Nov 21, 2014 (Mark Puumala) - Blanchflower (2007) describes the Murray-Stewart showing as an epigenetic replacement-type vein of argentiferous galena with attendant sphalerite, pyrite and minor chalcopyrite. The vein occurs in a shear zone that is hosted within rock described as porphyritic feldspar tuff.The principal vein was traced for approximately 35 feet. It consists of several lenses, which swell to a maximum width of 8-10 inches, and within a length of 3 feet, pinch out to faint stringers. Blanchflower (2007) reported that the shear zone is oriented 297/73. The mineralized vein has been traced over a strike length of 125 m and varies in thickness between 20 and 25 cm. Blanchflower (2007) has also noted this occurrence is located along a major northwest-trending geophysical lineament that covers a strike length of at least 5 km between Wilkens Lake and the northern arm of Favourable Lake. The most notable structural feature in the vicinity of this occurrence is the approximately 300-striking Bear Head fault zone, which is located immediately to the south (as shown on ODM Map 2262). Geological information compiled by Blanchflower (2007) also indicates that foliations in the area generally trend 300 with steep northerly dips, and that this fabric is axial planar to commonly-observed tight/isoclinal folds. North-trending and northeast-trending faults are also reported to occur in the area.

Nov 21, 2014 (Mark Puumala) - Blanchflower (2007) reported assays of 2720 g/t Ag, 28.6% Pb, 1.39% Zn and 2930 ppm Cu from a 40 cm chip sample collected across the vein. A similar silver assay of 89 oz/ton (2523 g/ton) was reported from this occurrence by Hurst (1929). Although this showing was diamond drilled in the 1960s by North Rock Explorations (AFRI# 53D16NE0015), no assay data are provided in the assessment files.
