No, i just asked the following question by email and got this answer:
Q - "Are you able to advise of an approximate timeframe for the listing of SAML (congo Copper) on the AIM exchange?"
A - "It is still anticipated for Mid October 2007"
i dont really know what they have to announce to the ASX but i assume as soon as they have more official confirmation/dates/details they will announce.
Cheers,
