The trick is to ask questions, smart questions that even a Yes or No or Can't commnet answer still gives you the needed response. And yes we should avoid obvious questions that won't provide any additional information.

For example, last time I spoke to AE, I asked 'Has any of the testing to date been disappointing or considered even a slight setback?" He said NO so that helps to validate the questions that some on other forums had raised about the delays in testing (swhere some thought it was because they were having trouble scaling up the process).

So, the questions have to be smart ones in my opinion.

Here are a few to ponder:

1. Of the NDA's signed, how many are research facilities/projects, how many are miners, how many are end users?

2. How will the sales price(s) in the PEA be supported? Will any of the supporting documentation be public or will it be protected by NDA's? (I assume the PEA will have several price scenarios but the market may once again yawn at the PEA IF there is no publically released sales price confirmation).
