IMO predicting when this will happen is meaningless. WE have no idea! The PRs and the ‘World’ direction, we do know.
Demo trial likely will tell us the speed at which it is operational because processing onsite is HUGE. Nothing to do with what is underground, which really feels like right stuff, right time, right location. Big time.
I admit I’m am clueless on competing underground similar material, regardless location or how far from getting it to surface.
