Ann: First 4N HPA Produced from Demonstration Plant, page-24

Great announcement today, which has greater import than many may appreciate.
The TECH Project's flowsheet shows the aluminium precipitation step occurs before the main solvent extraction to produce our headline nickel and cobalt sulphate, so it must influence the design of those critical units:

Now Lava Blue's demo plant's finalisation and commissioning delays have been overcome, IMO we can expect SG will be driving quick progress on this workstream to get 60 of those kilogram batches cooked, to complete the design of the commercial scale plant and offtake marketing efforts.

This will be possible as shown by this snippet: "...tested for purity in the QUT laboratory that is dedicated to the Lava Blue HPA project"
From the June 15 production of the composite sample till today's announcement is a mere 5 days, or 3 business days!

The team expect the new kiln impurities to burn off and reduce the contaminants on future batches, which should also assist in speeding up the process, and truncate customer qualification.
It may also be what K-SURE have been waiting on perhaps?

BTW, Lava Blue's QUT team get a photo mention in the 2023 Critical Minerals Strategy released today:
