RE:RE:RE:RE:RE:Straight From The Horse's Moutholdsalt, I look forward to watching someone build a simple cavern design that works in real time.
It is absolutely baffling to me how potash companies around the globe promote a viable horizontal selective solution cavern designs that "works" ;) yet they all default back to techniques that have been proven uneconomical in the last 65 years of trying including during cycles that have enjoyed record potash prices.
It's long overdue that someone changed that by building a proof of concept mine thinking outside the usual parameters of cavern development.
