As for ZHCLF shares at .16,  i think it is extremely difficult to buy shares and would be impossible to buy huge lots. I bought  4000 shares and it it took me 1 week  to  fill at the ask .

I've not found it too difficult to buy larger lots. It takes some patience and you have get a bit creative with order timing and price.  We've probably got years to go so lots more shares will likely be available.  Hopefully buying at these prices will turn out to have been a good idea.  I'm not 100% convinced.
