Ann: Brine Extraction Achieves Name Plate Flow Rate, page-28

I am only invested in SO4 but watching KLL and could tip some $$ into them. just not certain they have washed out all their bad news just yet. when SO4 are up and running I think KLL SP will get dragged up. love the sector and would like to place the chips on both these companies, when time is right. your question on trench height; question is one for a Hydrogelogist (which I am not, but our friend Brain Fart has a shoulder tapping, bed side relationship with one), full trench is just a big body of brine acting as a hydraulic plug. from all my reading you need to be pumping out of the trench, drawing the level down as much as possible, to promote the flow into the trench from the aquifer. lots of big words I don't understand but basically creating a flow pathway into the trench. if it's full nothing can flow in
