Stock Factory Interview, page-41

Chris,

You stated that it would cost more for the extra beads than what could come in as extra profit from increased recovery rate. I just asked you how you came up with this.
Can you please share the exact cost of beads?
If you can't, your statement is just simply unsubstantiated.

Steve must know the costs, and he said that with rising lithium prices, it's something to reconsider. He also added that he is waiting for confirmation from the engineers, whether the process flow could accommodate this, so no one says at this point that it is a done deal.
