next mmr trading halt get into pep11 via gba ?

Anyone remember the MMR trading halt commencing 2 June 2008 until 4 June 2008.
Anyone remember that during this time when MMR shares in trading halt mode that it was business as usual for trading in GBA shares.

I note that the MMR price sensitive Advent Energy PEP11 Update ASX announcement of 1 February 2010 also that day filtered through to become a BPH ASX announcement. (non price sensitive) But interestingly silence on the GBA scene in this matter.

Very interesting bearing in mind that :-
(a) MMRs primary beneficial assets are beneficial direct & indirect interests in Advent Energy & its PEP11 permit
(b) BPHs primary beneficial assets are beneficial direct & indirect interests in Advent Energy & its PEP11 permit
(c) GBAs primary beneficial assets are beneficial direct & indirect interests in Advent Energy & its PEP11 permit
In a nut-shell what is difference ?

If same practice (of Advent Energy PEP11 related announcements to the ASX being an MMR ASX announcements & a BPH ASX announcement by not a GBA ASX announcement) is to apply in future then Id suggest the next time there is a trading halt in MMR shares & perhaps BPH shares that then may be an opportune time to come under the radar to acquire some GBA shares

Perhaps someone knows the rationale as to why silence on the GBA front when MMR & BPH getting the Advent Energy PEP11 Update ASX announcements

Interesting ramifications. heh ?
