I know bugger all about stock chart analysis but a thing or two on chemistry.
the result are only for the first step of the process call "leaching", I.e. fine crushing the ore and dissolving it in acid.
this step is critical for overall yield.
97 % is excellent, and even better is 95% after 15 minutes which means the could reduce the size of tanks by 4 times to produce same throughput as other which normally use 1 hour retention time.
Giyani achieved 93% adding a reductive agent (sucrose). E25 hasn't stated which agent they used. Peroxide and SO2 are other options, but 97% is absolutely fine.
For a PFS, they can simply used assumed %yield for the other steps (like Giyani did). And keep on researching the process to make HPMSM ready for the DFS.
below is Giyani yields
looks like our ore is very amenable indeed.
I would like E25 to send bit more money on this study which is critical and I reckon they got sufficient millions to afford a world recognized lab/university to do so....
