Looks like someone knows that ASX announcement is about to happen regarding proposed sale of Indophil's interests in Sagittarius Mining (which owns Tampakan).
You can do this anonomously if you wish.
It traded all day between 92.5c and 94c until 3.55 pm when trades were at 96c then large bids and closed in aftermarket at $1.03.
Almost 700,000 traded after 3.55pm of a total volume of 1.055 million for the day (i.e. almost 70% of volume occurred in last 5 minutes and in the after market and these were mostly large bids)
