Can't help specifically but in the PFS the nickel price adopted was $7/lb + $2/lb premium for sulphate. The price for cobalt was $25/lb with no premium specified.

I think it is reasonable to assume that the sulphate premium for cobalt would be similar to nickel, thus not impacting cobalt nearly as much as the nickel percentage wise. I assume this is why no premium was adopted in the PFS.

Further, at current prices cobalt only accounts for about 15% of revenue compared to about 50% for nickel, so I'm not to concerned about the cobalt price.
