Ann: Investor Presentation, page-3

I thought this was an excellent presentation. Clarifies a lot of questions in my mind. Management view seems extremely upbeat and I've been around a long time investing ( 40 years) and by now I've honed my skills at sifting out whether things pass the "pub test" and I give this a big tick. The presentation itself is well constructed, and so straightforward. The one thing that caught my eye and I dont recall any earlier comment is that one of the slides indicated some limited de-pressurization testing has been done and it was successful for releasing Helium from the water/fluid. That took me by surprise. Or have I misinterpreted this ?
