Lithology Comments

Nov 02, 2017 (A Wilson) - WKT Cobalt Occurrence, Best Township The WKT cobalt occurrence is in Best township south of the southeast end of Rib Lake. The occurrence consists of a vein, less than one inch wide, striking N70°W., and dipping 78°N. that intersects Nipissing diabase. In the vein galena and pyrite are present in carbonate gangue; in the wall rock at the margin of the vein is disseminated cobalt arsenide. A pink aplite dike up to 5 inches wide is near the vein. At the time of the writer's visit exploration of the vein was only started; a preliminary sample showed silver present to less than an ounce per ton.

Nov 02, 2017 (A Wilson) - The WKT Cobalt occurrence is in Best township south of the southeast end of Rib Lake. The occurrence consists of a vein, less than one inch wide, striking N70°W., and dipping 78°N., that intersects Nipissing diabase. In the vein, galena and pyrite are present in carbonate gangue; in the wall rock at the margin of the vein is disseminated cobalt arsenide. A pink aplite dike up to 5 inches wide is near the vein. At the time of the writer's visit (1965) exploration of the vein was only started; a preliminary sample showed silver present to less than an ounce per ton. A pit less than 10 feet deep and trenches had been put down on the vein many years previously. In 1965 prospecting and exploration were being done by the WKT Mining and Exploration Co. Presumably the vein had been discovered about 1910; the claim on which it occurred then was designated HR.1446. The numerous, and in places deep, trenches in the vicinity showed that at that time the surface had been carefully prospected.
