1910: The vein upon which the main [provincial] shaft was sunk, though showing much native silver at the surface, did not prove persistent or rich in depth, and the Department had the alternative of spending a further sum, probably a large one, in the endeavour to find payable ore, or of offering the property for sale and permitting private enterprise to supply the capital for the test and reap the benefit should it be successful. 1910-1923: Cobalt Provincial Mining Company Ltd. property acquired; 1924-1925: Clifton Consolidated Mines Ltd. – extensive underground work. 1938-1968: drifting and raising; 4-DDH; small scale mining and salvage opertaions have been continued. 1941-1953: Cobalt Products Ltd. – underground workings; DD-4. 1971: Teck Corporation Limited – mag and EM surveys. 1998-2007: Cabo Mining Corp. – DD-13-1910.51 ft.; geological mapping, stripping, sampling.

Aug 02, 2017 (A Wilson) - On the dump of shaft No.2 are pieces of black carbonaceous bedded Keewatin sediments. This may indicate that the easterly extension of the band of Keewatin sediments exposed at surface in the southwest corner of Nipissing claim R.L.406 passes through the No,2 shaft workings. The Cobalt Series which is 50 ft. think in the western part of the claim thickens to 350 ft. in the east part of claim where it occupies a paleovalley trending NNE in the Keewatin surface. The Cobalt series is underlain by steeply dipping black carbonaceous Keewatin sediments in the eastern part of claim in the vicinity of shaft No. 2.

Aug 02, 2017 (A Wilson) - No.2 shaft vein and No.1 shaft vein furnished almost the entire production. Shaft No.2 vein strikes N.65ºE. and dips vertically. Gareau in charge of exploration for Cobalt Products Limited, reports that the vein carried silver only in the conglomerate above the bedded greywacke (217 to 242 feet below the shaft collar); below this was cobalt mineralization, which in places was disseminated through the sediments and difficult to recognize. In No.1shaft vein, very high grade silver occurred but the production was disappointing. Near shaft No.3 minor veins strike N.25ºW. No clear cut relationship is apparent between the position or metallic content of the veins and the well-marked trough-like depression in the Cobalt series – Keewatin contact.
