Gotta love the US buying...in the past PYRNF rarely traded more than 100k shares. Yesterday 463k and thus far today 336k. IMO it might have to do with the pending uplist to NASDAQ along with CW's followers. Some folks perhaps taking advantage of the bargian before PYR's official start of NASDAQ trading. With 40-F now filed with SEC, it's likely now a box checking exercise before final approval
