Hi sally,
I saw in your previous message you said something about AirScience not having any news releases, I would like to kindly provide for you this link https://www.airscience.ca/blank where they release their news. I dont know if I am correct, but if it is a private company, they wont be releasing press releases like you would see through a broker news feed.
Also, dont be so absolute on your opinion regarding AirScience. "no way" they are operating out of the address listed? Well its probably a management office and not manufacturing facility. I will admit I havent done enough DD to speak with authority, perhaps you know things that I dont. What I do know is that although their website looks like it was made in "10 minutes" as you say, the content of the science and their process is solid. PYR wants the technology, not their office.
Godbless.
PS: My condolences Peter.
