usa trip, page-3

That is very good news.
In the quarterly they stated that:
"The previously reported visit from Alcoa USA has been postponed until the completion of the technology upgrade, though Managing Director Frank Rogers and Executive Director Ben Mead will be visiting the USA during November"

So it looks like this visit is to see Alcoa and it's great to see it happening so early in the month.

I can't see any reason for them to physically go to the US except to try to finalise deals. Standard negotiations don't need people to be in the same country. I don't think the SSC agreement involved anyone coming to Australia, or going to the US

So they'll be there now, with discussions taking place over the next day or two. Hopefully a trading halt Monday.

None of this will happen though if they are just going for a weekend in Vegas.
