Ann: Blackstone's Piloting Success, page-12

I think your circuit 2 is off.

"In addition, the mixed hydroxide precipitate (“MHP”) re-leach process has been
piloted with third-party MHP (with a piloting run time of 635 hours) to produce
battery grade nickel and cobalt sulphates suitable for battery precursor cathode
active material (“pCAM”) as verified by ALS."

"In the coming month, the MHP produced from the TKR feed blend will be processed to complete the pilot campaign."

"Battery grade nickel and cobalt sulphates have been committed to potential partners for pCAM processing and performance testing."

I think the material flow chart is as follows, with the pCAM pilot testing still outstanding.

Ni Conc -> MHP -> Sulphates -> pCAM
