Lithology Comments

Oct 30, 2020 (Sheree Hinz) - Keewatin rocks exposed at surface consist largely of andesitic lavas; two interflow sedimentary bands are exposed. The band between Shafts 2 and 3 is bedded chert mineralized with sulphides and tuff and volcanic fragmental rock difficult to distinguish from the volcanics.

Mineralization Comments

Oct 30, 2020 (Sheree Hinz) - Mineralization of silver and cobalt occurs in narrow pink carbonate veins but copper and zinc mineralization occurs in sulphide rich volcanic interflow beds. On the dump of shaft number 2 and on the dumps of other excavations on the vein, pink carbonate vein material with chalcopyrite and cobalt mineralization is quite minor. A small sampling program (9 samples taken) done before 1960 found the highest silver assay to be 7.2 oz/ton Ag. A drill core sample taken from the mineralized interflow sediments gave an assay of: 1.95 oz/ton Ag, 5.06% Pb, 0.66% Cu, 1.95% Zn, trace Au, trace Ni, trace Co.
