"That leaves the other 80%, and, to gain an outright majority, more than 62.5% of that 80% need to vote in favour."

I think your math is off. From all I have read we need a majority of VOTING shares. Which means that neither absentees, abstentions nor Glencore (5%) will count.

So, if there were 100 shares outstanding, and 20 shares controlled by YTG were voting against, all we would need is 21 of shares voting FOR the proposals.

In other words: A mere 21% of capital could suffice, assuming no one but YTG votes against the proposal.
