Dec 07, 2005 (B Nelson) - Walters Township is underlain by east-trending, isoclinally folded, and faulted mafic to felsic metavolcanics and metasediments. Mafic metavolcanics include andesite and basalt, typically pillowed or amygdaloidal, and minor tuffs. Discontinuous chert, oxide iron formation and sulphide iron formation layers are interbedded with the metavolcanics. Diabase dykes intrude all rock types. Quartz +/- carbonate veins are hosted in sheared mafic metavolcanics and are observable on or near an overgrown baseline in a series of trenches. Veins have various attitudes and appear to represent a stockwork system. Mackasey (1976) described a cribbed trench, now partially sloughed in: A 12-15 cm wide vein strikes N75 degrees E and dips 80 degrees S. Wallrocks are altered to sericite and carbonate. Veins are laminated (crack-seal texture) or brecciated. Quartz is typically medium to coarse-grained. Up to 15% combined asp and py, with minor cp, occurs in the vein. Asp occurs as a 'fine-grained', dark grey, sugary disseminations and as silver striated prismatic crystals up to 5 mm long. The most westerly pits of claim TB302466 were sunk in quartz-feldspar porphyry hosting disseminated sulphides.

Dec 07, 2005 (B Nelson) - Flow rocks are fine-grained and dark green to greyish green in color. Metamorphic grade is greenschist facies.

Dec 07, 2005 (B Nelson) - Diamond drilling in 1972 (DDH 1) intersected spectacular visible gold, some coarse, in one quartz vein intersection of 2.0 m. Possible tetrahedrite was noted in the drilling. Conwest intersected gold values up to 2.54 oz/ton Au over 0.21 m in their 1973 drill program (Hole 1063-73-2, Sample No. 1729). Mackasey (1976) reported the following: vein chip sample over 12-15 cm assayed 0.05 oz/ton Au; host chip sample over 30 cm assayed 0.10 oz/ton Au; selected grab sample assayed 0.38 oz/ton Au.
