PEAVery attractive after-tax NPV and IRR + VERY LOW operating costs at $3,656 vs. $4,300 for SLL.
Keep in mind that this is only the PEA - as R&D continues, costs and capex commonly come down, improving the economics. Plus, as we all know, a lot of room to increase resource size, which would improve economics if they increase annual production with it.
A very strong starting point (and even ending point if that was the case) in my opinion.
