ONTARIO – Canada Cobalt Works, based in Coquitlam, B.C., is setting up a Re-2OX pilot plant at the Castle cobalt-silver mine in the historic Cobalt mining camp. The plant will produce bulk gravity concentrates for immediate processing into cobalt sulphate.

The pilot plant will operate at a rate of 500 t/d, with concentrate production beginning in Q3 2018.

SGS Lakefield is already precipitating metals from Castle mine concentrate and crystallizing cobalt sulphate in its lab. The metals are being tested for their suitability for the manufacture of batteries. With a higher volume of concentrate, SGS can scale up their testing.

Canada Cobalt continues drilling at the mine. Visible cobalt, nickel sulphides and native silver were seen in the cores from the first three underground holes on the first level.
