RE:Market sizez I they can prove to scale that Purevap can produce 3 Nines plus, using low grade feed stock, the resulting cash stream would be magnificent , around $3/share? Now if only they had ready sources of low grade quartz at virtually no cost... oh wait, they do! Make that $5/share!!! Come on 1/1/2017 - I need more TFSA shares! In my opinion only. Thanks- Buda
