With out a doubt, the board members on ARL are indeed industry veterans, remember they all talk with one another, all the big boys and players, most all friends. Ian and Mick used to work together from the early days.. from the history I have gathered.

The implications, well if you are adding further refinement steps in the process it adds to the CAPEX figures of course, Ion exchange can have its draw backs and downsides in full scale processing, teething issues..

I am going to only deduct my opinion and assume they went down the SGS laboratory conditions for final Sulphate testing to I'm only guessing identifying the issues precedent with processing and using the Neautralizer, in the process flow, and how it reacted in the process philosophy, again maybe thats why IX had to be used. (IMO) as normally you can go MSP -> POX -> SX -> then use steam to produce the Nickel/Cobalt sulphate crystalization

Test work is good, it's good to determine base line and work out acid consumption, lime, reagents etc. Residence time through HPAL, leaching times, etc.
