First Cobalt examines mineralogies of historical mines
from Canadian Mining Journal
Toronto-based First Cobalt Corp. has examined the mineralogies of samples from several historic mines it owns in the Cobalt camp 400 km north of Toronto. The company found high grade values and various styles. The highest grade vein style mineralization was found in muck piles throughout the camp. Containing up to 9.22 per cent cobalt and >5,300 g/t silver, First Cobalt considers them to be representative of historical ore production. The fact that the veins contain similar mineralization points toward using a consistent flowsheet for milling that ore.
