1905-Silver-bearing veins were discovered in1905; extensive exploration and development began about 1909 and were extended until 1918. Work discontinued at mine; surface was well prospected by trenching (9800 ft. trenched up to Jan 1 1911). A considerable part of the total shaft sinking done on the claim had been accomplished by the same date. 1920: All work discontinued in 1920 but resumed on a small scale about 1925. Operations continued until 1927. 1942: Cobalt Products Limited: carried on underground operations to a modest extent. 1944: Silanco Mining and Smelting Corporation Ltd. – extracted ore from provincial shaft No. 2 1946: Ausic Mining and Reduction Company Ltd. – new headframe constructed; shaft rehabilitated, and underground operations and diamond drilling continued until 1949

Jul 26, 2017 (A Wilson) - The presence of pieces of bedded cherty Keewatin sediments on the dump of No.2 shaft indicates that cherty bands occur in the Keewatin below the Cobalt series in the vicinity of the shaft. Disseminated base metal sulphides occur in minor amount in the dump pieces. The thickness of the Cobalt Series sediments ranges from about 300 feet in the northwestern part of the claim to less than 100 feet in the eastern part. Most of the claim lies on the southeasterly flank of the Cart Lake trough using this expression to mean the trough-like depression in Keewatin rocks presently occupied by Cobalt Series sediments; the axis of the trough, in direction N20ºE, passes in the vicinity of the northwest corner of the claim. The Cobalt series is made up of an upper conglomerate, a well-bedded greywacke member and a lower conglomerate. The upper conglomerate member occurs over much of the rock surface of the claim; its nature varies greatly from place to place; in some places the pebbles are in quite minor amount and the rock might be called a greywacke or arkose. The well-bedded greywacke is exposed near the east side of the claim at the Meteor No.2 adit (about 50 feet west and 150 feet south of the northeast corner of the Savage) as well as at the inclined shaft 120 feet W. and 700 feet S. of the same corner. The dip of the well-bedded greywacke member appears to be considerably flatter than that of the underlying Cobalt series - Keewatin contact, entailing marked differences in thickness of the lower conglomerate member from place to place.
