I think the PFS had a lower than expected level of resource incorporated, and given capex was always likely to be fairly high, relatively low IRR; hence the ST SP kick in the pants around that time.
Since then CEO stepped in with a big on market purchase, and the positive newsflow has resumed. IMO market now forward looking again re potential rather than ST re-rate of BFS which pushed the pre-release spike as those ST traders exited. "Back to work" mode now pushing through more high-grade drill hits.
As others have pointed out, lots of drilling to go yet in areas of highly prospective mineralisation; the BFS will likely make for much more interesting reading further down the track than the PFS did IMO.
