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. Flow rocks are fine-grained and dark green to greyish green. Discontinuous chert, oxide iron formation and sulphide layers are interbedded with the metavolcanics. The Ledger Occurrence is described by Burr (1982) as a number of pits and trenches over what appears to be a mineralized breccia fault. Stringer and massive sulphide mineralization occurs throughout, consisting mainly of pyrite with lesser amounts of chalcopyrite. An old trench some 152 m to the west of the same anomaly is described as containing heavy to massive sulphides, mainly pyrrhotite. A small exposure of tuffaceous chert with abundant pyrite stringers near the south boundary of the claim group. The pyrite stringers follow fractures that parallel the foliation. The chert is terminated to the east by a diabase dyke.

Dec 07, 2005 (B Nelson) - One grab sample from a trench assayed 0.50 oz/ton Au. A grab sample of heavy to massive sulphides assayed 'slightly better than 0.01 oz/ton Au.' A grab sample of the mineralized chert was found to contain 0.28% Ni and traces of gold and silver.
