These guys have a master plan for Queensland CSG brine repurposing and it's quite concrete and well documented. In his Strawman interview, I think the CEO hinted that a milestone would be announced around the AGM. Nothing yesterday, but it still seemed very much in play.

It is apparently a legislated requirement that Qld CSG operators look for a way to create products from their brine wastestream and Parkway have a solution to create critical industrial chemicals. They have been working on it for a long while with major players who ultimately do not want to run a treatment plant, they want someone else to do it for them.
