The answer to my own question:
The Schemes will be implemented on Friday, 18 February 2011 and the dispatch of holding statements for Alacer Gold CDIs and certificates for Alacer Gold shares will commence on this date.
Alacer Gold CDIs will commence trading on ASX on a normal settlement basis, and new Alacer Gold shares will commence trading on TSX, on Monday, 21 February 2011.
Monday 21st is the day. Statements being sent from today...
