Ann: Ore Supply Agreement Executed with SMT, page-65

Thanks for your rigour @Embista,@PieChart & @OStirz.
I've added a cobalt metal v sulphate and nickel metal v sulphate table in the bottom left as a comparison.
For cobalt, PieChart's BMI chart, with two options US$10K/t - a bad case /recession scenario & a US$12K/t which seems more like the average over the past few years (note COVID would have played havoc with the average) without even considering a forward looking critical mineral supply deficit figure!
The 12K figure seemed to give equivalent-ish revenue to the PFS cobalt metal revenue.
For nickel, flying a bit blind as I don't subscribe to any price platforms, found a recent figure from FastMarkets, and plugged in a lowball US$4.5K figure, which gives an equivalent revenue to the PFS metal revenue, and then a US$6K/t which is still lower than the FM figure I found.
So on balance whichever price it seems the numbers look just as good, if not a deal better
Enjoy your weekend all, MM.
