Ann: Investor Presentation - Resources Rising Stars, page-49

I think stage 4 testing was extended to encompass further tests (I could be wrong but that springs to mind w/out going back over recent ann's). maybe they are still ongoing (??). I also think that the updated MRE due to be announced prior to PFS would be based on the results so either way they are coming out sometime in the next weeks/month.

Totally agree with you @andrew1401 the waiting & delays have been incredibly frustrating..... but GRV are paving the way here with these resources so I imagine there has been much learning through trial & error only. Initial pyrolysis method obviously not profitable enough so they went back to the drawing board. the next few months should be very revealing and yes my fingers (and toes) are crossed that there is no further delay into Q3 or Q4..... but who knows.
