some questions

I have a couple of questions for some of the longer term holders/watchers:
- What is the potential liquidity like in IDM? We haven't seen more than 1.3m change hands since Dec last year. How tied up is the portion not being held by mgt and the banks?
-Are they looking at a US listing, I couldn't find any reference to this?
-Ambitions beyond the current plant/mine? They seem on track to deliver a strong cash business, will they hoard and look to expand or settle in for a while and pay some dividends in the meantime?
