Ann: Koch Technology Solutions Pilot Unit Delivered to GreenRiver, page-54

At the end of the day both Sunresin and Koch tech is being used for testing of both brines, Green river and Paradox.
The company has never stated that the Koch tech is no good for Paradox brines, maybe it is maybe its not, and they also never have said that they wont be testing Paradox brines also, we will see.
I would rather not jump to any conclusions, but I do solely rely on my intuition for almost everything.
I suspect that Koch will be as good as Sunresin if not better for Paradox brine, so my intuition is telling me that Sunresin will end up being replaced with Koch for both projects.
It just makes logical sense, and may end up happening, even though it is not the companies current plan, but things change.
