RE:Revised Timeline? I don't think it is a new revision.
In May, Lewis presented at the IIF and shared Almonty's current investor presentation. The timeline in that presentation shows Q2 2024 as construction complete and mining activities starting. The official timelines can be reviewed on slide 15 of investor presentation.
I believe Lewis has suggested construction could be complete before then with an earlier start to mining activities; however, in the presentation they have been conservative with their estimates.
I think when the current presentation was complete Almonty was still waiting on the final piece of the mill or some other long lead time equipment to arrive on site. The equipment is now on site so this could speed up construction a bit.
