so , researching Zeolite , and this is my first conclusion, page-5

Zeolites are not traded like minerals - they are industrial chemicals and price will be non-transparent and negotiated through individual contracts. We've been given a likely price range for Zeotech product (in the latest ann - "...Zeotech’s strategy to produce highvalue Type A molecular sieve synthetic zeolites, which achieve prices in excess of A$2,850per tonne". Zeolites are "made to order" in terms of quality and form and some high-value uses will demand very tight specifications and correspondingly high prices. We don't yet know much about Zeotech's cost objectives or likely main markets. The key (IMO) will be getting a few profitable binding offtake agreements to fund expansion and further research. We are a fair way from that stage and can't really model economics with the info we have. For me, this is a medium term, highly speculative play. So far, so good.
