Oct 30, 2020 (Sheree Hinz) - The claim, except for a small area in the southeastern corner, is underlain by Keewatin volcanics, which consist for the most part of andesitic pillow lavas. In the western part is a tongue of felsic volcanics which includes a large amount of breccia. In the vicinity of shaft No. 2 the geological relationships are complicated; several bands of sediments, in part carbonaceous, occur in association with intermediate and felsic volcanics.

Oct 30, 2020 (Sheree Hinz) - A vein in the Buffalo North shaft carried small amounts of silver and cobalt but was too small to work. This vein pinched out when it reached the underlying Keewatin. At No. 2 shaft a vein occurs in a Keewatin sediment. On the dump plentiful gangue material, both quartz and calcite may be seen, as well as cobalt arsenides and arsenopyrite; chalcopyrite is unusually abundant.
