Definitely very possible the excitement recently is via ARK ETF...PYR is definitely on the radar with very big players.  Extremely exciting for PYR...and this is just 1 division 3D Powders. 

DROSITE, TUNNELING, PUREVAP NANO, TORCHES, US MILITARY WASTE ETC....each on it's own can morph into something unimaginable....soon!

ARK holdings 
As of Jan 20.2021 (PYR is noted at #39 recently bought 89,000 shares...NOW today at 98,300 at close today...surely more is to come):
