Aug 01, 2017 (A Wilson) - The claim is underlain by Keewatin volcanics, which are intruded by basic intrusives. The Keewatin consists of well bedded tuffaceous sediments, dipping steeply to the south and smaller amounts of andesitic lava. The wide basic intrusive shown on the map parallels the strike and dip of the sediments; it is regarded as a sill related to Keewatin volcanism. In the western part of the claim the rock shown as lamprophyre is thought to be part of a sill dipping westerly at low angles.

Aug 01, 2017 (A Wilson) - Veins with cobalt and minor nickel mineralization occur on the property; silver is also present but in such minor amounts as to be of little economic significance. The writer has no record of any cobalt production but possibly a few pounds might have been obtained. Veins Nos. 4 and 5 as well as the cobalt-bearing vein on the shore of Sasaginaga Lake appear clearly to be westerly extensions of Trethewey veins which were highly productive in the Cobalt Series sediments. A vein exposed in a 10-foot pit, 650 feet west and 350 feet north of the southeast corner of the claim, that is the shore of Sasaginaga Lake, is believed to be the westerly extension of vein No. 4. In the pit veinlets of calcite and quartz carry cobalt arsenides and chalcopyrite. A. E. Tyson kindly furnished the writer with the assay results of this sampling. One vein, width 0.1 feet and with 20 % metallic mineral, gave an assay return of 2.40 oz. silver per ton and 13.04 per cent cobalt. Samples, other than on this vein, gave very low returns. Western extension of Tretheway veins assays to 82g/t Ag; 13% Co.
