@cargoJust glanced over the new $HPQ investor deck and noticed something that I do not recall was on any of the previous decks with our fumed silica process.

"The process feedstock is Quartz not Silicon, this will make its Capex a small fraction of what is required to build a traditional Fumed Silica plant"

This will also give $PYR/$HPQ another massive advantage over the existing legacy fumed silica process due to use having the ability to use (cheap as borscht quartz feedstock) and not silicon halide which requires more processing steps with harsh chemicals adding to the Capex costs plus more toxins release into the atmosphere.

Below if interested is Cabot's patent on their fumed silica process.  "The process comprises providing a silicon halide feedstock comprising about 80% to 100% methyltrichlorosilane, combining the silicon halide feedstock with hydrogen gas and oxygen gas to form a reactant mixture, discharging the reactant mixture out of a burner, and combusting the hydrogen gas and the oxygen gas of the reactant mixture so as to hydrolyze the silicon halide feedstock to produce fumed silica"
