In the May 04 NR Link here they said that their attempt to do a pour failed but they were starting the next series of tests ( series #2 / Yield and series #3 / Purity). During these series of tests they will have other attemps to do a pour, they do need to do tests solely to achieve the pour.  A few days later Bernard, in interview, said that for them the pour is a non issue, they know they will do it successfully, that the pour and the video of it was more for public relation "i.e. it is nice for the share holders to see it".  Since that NR they have not released the results of tests series #2 and #3.

A while back, Bernard said that improving the yield will have the effect of also increasing the purity.  We can understand that this is why they are working on yield before testing to achieve better purity.  Although 3N is what the battery industry needs, Bernard is convinced that QRR will produce 4N and possibly 5N.  Again, the next NR related to QRR could be explosive.
