In my opinion, MNM would not be chasing up all the brown coal deposits that they can before the bulk sample results if they think it wouldn't work... Also, exergen might be a small company, but they have huge backers, with deep pockets... They would not be investing in a small company if they think they couldn't hit the big time...

Also all the testing prior to this has come up positive, they have spend alot of years refining this process, i would be very surprised if the bulk sample testing does not meet expectations...
