Aug 14, 2017 (A Wilson) - Steeply dipping Keewatin pillowed andesitic lavas and tuffs with interflow sedimentary chert beds occur. The flows strike ESE and face NNE. The Keewatin rocks are overlain by Cobalt Series conglomerate from 0’ to 100’ thick which, in turn, is overlain by gently east dipping Nipissing diabase in the east part of the claim.

Aug 14, 2017 (A Wilson) - Four silver- and cobalt-bearing veins, designated W-1 to 4 on Map P.96, were discovered on claim A 23, These traverse Keewatin rocks. W-1 is closely associated with an interflow chert band. In claim A 37 at about 130 feet S. and 250 feet E. of the northwest claim corner a calcite vein1 with cobalt mineralization is contained in Cobalt Series conglomerate. The vein is less than one inch wide and has a northwest strike. Spotted chlorite alteration has been observed in several drill holes on this group. In drill holes S-6 and 8(on claim A 23) it is strongly developed in Keewatin rocks;in drill holes S-9 and 10 (on claim A 26) it is present in Keewatin as well as Cobalt series; in drill holes 1961-6 to 9 (on claims A 37 and 39) its presence in the Cobalt series is recorded by Benner. At about 450 feet westward of the southeast corner of claim A 39 alteration of Cobalt Series greywacke is so intense that identification of the original rock is somewhat uncertain.
