Ann: Voluntary Suspension, page-69

Correct me if I'm wrong but the trading halt was put in place once they became aware of a large price sensitive announcement, which was to draw up the paperwork (this is an ASX rule that they cannot withhold sensitive information they must announce it once known else risk a fine unless certain criteria is met) so they've spent the past few days ironing the announcement out but feel they need a bit more time to do so. Its not them trying to add suspense or playing with the market its just they obviously have a major but of news to announce and need more time to do it correctly.

Sit tight this will be a rocket in no time!
