Trading (and announcement, if any) will be open tomorrow morning only. Read the announcement again:
The Company requests that the trading halt end on the earlier of the commencement of normal trading on Tuesday, 15 September 2015 or when the anticipated announcement referred to above is released to the market.
So wait till tomorrow. No need to panic. Everything is in order.
