I hope others have checked into this out as well, the big question for me is:  What does it mean?

I'll take a stab, but this is just a stab. 

I think its very possible that the quantity of 1,100,900 represents the number of shares that are still subject to TSX Buy-Ins due to delivery failures, that is to say I think its a "pending" quantity.  I will check tomorrow to see if the quantity changes and by how much. 

If we see house 100 buying 100,900 at 3PM tomorrow and then see this spreadsheet is updated and shows the quantity as 1,000,000 even...or if the numbers similarily correspond, then I'll take that as pretty much rock solid confirmation that this opinion is correct.  

I checked the other stocks on the list and didn't see any house 100 buy-ins.  Perhaps its a case where the number of delivery failures has to reach a 'critical mass' or something along those lines.  

I'm also thinking that, for anyone looking to take some cash out of RVX....that we could inflict some pain by putting limit sell orders in to push the market so to speak.  Thinking (or writing) out loud I'm wondering if I put a sell order in for a few thousand shares @ 10% above $2.20...so for $2.42....I'm wondering if MMs would move the stock up to that $2.20 level to force those who are naked short to buy my shares at that 10% premium.

Its just a thought at this stage. I'm also thinking that the shares in my margin account, that they might have already been loaned out in any case.  But the shares I hold in my RSP and TFSA accounts are supposed to be unavailable to short sellers and thus should be able to satisfy delivery failures.   

If I'm right on this, locating 1 million + shares could take a while...if shareholders have a tight grip, a very long while.
