RE:Resource ???E3 has scaled up the DLE process TWICE in the lab, here is a link to NR with results from Lab Pilot Prototype completed 15 months ago. The technology works extremely well at that scale. The only de-risking step left is the Field Pilot which E3 expects to start operating in a few months (Q3/2023).

As for the rigorous Measured & Indicated reserve estimate, I suggest you do your own DD. Lots of recent NR's on this so you can do your own homework.
E3 is very well capitalized well into 2024 even before the steady stream of government grant funding that has been rolling in recently. When PFS is complete, there will be investors tripping over each other to tie-up supply by advancing the large funds needed. JMHO DYODD
