Very interesting..... Nov. 2020 @ 32 min mark.
Goal to extract addtl materials like potash & magnesium, etc..
From the pilot news:
"Throughout pilot operations, E3 Lithium will be testing its technology along with two third party technologies."
I'm 90/10 this is the "bolt-on" from the video. You're not going to wait to test for addtl materials, after you've designed the commercial plant.
Especially when like the CEO says in the video, the cost to extract those is covered in the Li extraction costs.
You test, design & co-produce them to lower the commercial capx & opx, even further.
