RE:RE:NASDAQ LISTINGThe 3 iron pelletization Clients (A, B, C) are all at different stages, the most advanced being the Client A with whom they are already in advanced discussion regarding the final terms of the contract.
So just this first iron pelletization client will set the tone.
Then, their upcoming Silicon EV battery one with a major car manufacturer due in December will show hw diversified its technology can be.
And we're not even talking about the tunneling contract (*1) that has been in the news since April 2020.
So PYR's CEO is not planning this NASDAQ uplisting without knowing where he's at.
And by the way, this Drossrite picture shows the Nevada or California environment. And that's from
from a North American Automobile Parts Manufacturer (as per the original news release of July 26, 2018).

But fr the moment, that's not what matters. What matters is the signing of these contracts, as they are all major industrial players.
