(Image: First Cobalt Corp.)[/caption] ONTARIO – Toronto-headquartered First Cobalt Corp. has begun metallurgical testing of high grade refinery residue and crushed waste at its mill in Cobalt. This study could provide the company with an early source of cash flow. Testing will be done on three piles totaling 6,500 tonnes with a historic estimate. The grades range from 0.65% to 1.55% cobalt, but they are not 43-101 compliant. One of the piles consists of broken rock from the old Kerr mines and mill. Another pile consists of previously processed high grade refinery residue. The third pile is a mix of both materials. The testing is aimed at creating a flowsheet based on the characterization of the samples, gravity concentration, hydrometallurgical recovery of cobalt and silver as well as arsenic removal and stabilization. Success could lead to treating historical mine material from First Cobalt’s many properties at its mill and refinery.
