KOO - I can't answer your query about why Agoracom doesn't post ZHCLF like they do RVXCF on the RVX board. I can only surmise it is because OTC isn't recognized as a real exchange and yet the do for RVX because it is also on the TSX so gets some cred there. Not sure!
Also, I queried IR about the Prommissory Note details like rate and maturity date but just got a reply refusing to give that info.
