If Alcoa are watching and assisting with the changes to the flow...

If Alcoa are watching and assisting with the changes to the flow in that recent run - and I think why wouldnt they be, at least they have engineers on site to assist and sign off on any changes made to the purposed plant and trial plant. So yeah I wouldnt expect news straight away until after they have digested all the information and written it up, had a chat about feasibility and future of any more improvements etc - that includes the quality of the HPA, as the HPA was a by product of this run really. The next pilot runs will be solely focused on HPA with Alcoa.

Its only been a week.
