Current plant commissioning works have successfully produced primary lithium product, which is being processed through multiple stages to produce battery quality lithium carbonate product

I read this as multiple stages are still required before battery grade is produced from the primary product, which one would expect before the end of the year according to the timelines previously given. There will likely be an announcement when first BG Li is produced as it is an important milestone for the commissioning works. Lots to look forward to.
