Aug 02, 2017 (A Wilson) - Keewatin rocks exposed at surface on the southwest part of the claim consist of pillowed andesitic lavas for the most part. Chert on the Airgiod shaft dump indicates the presence of interflow sedimentary bands as does also the presence of abundant pyrite mineralization. The thickness of the Keewatin resting on the upper contact of the Nipissing diabase is probably everywhere less than 100 feet. It is reported that the 90-foot level of the Airgiod shaft was in Keewatin rocks as well as in diabase.

Aug 02, 2017 (A Wilson) - During the Rix Athabaska option, 3466 pounds of cobalt, 1310 pounds of nickel and 1816 pounds of copper were produced. On the Peterson Lake property 240,000 pounds of cobalt are reported as having been shipped by the Silvertown mining interests. Assays from the Silver Century drilling returned values ranging from 4.7 oz../t. over 0.3 ft. to 959.9 oz./t over1.6 ft.
