mineralogy changes their stance

As previously announced to ASX, Mineralogy Pty Ltd (“Mineralogy�) has requisitioned
a general meeting of ARC Energy Limited (“Company�). In accordance with its
obligations under the Corporations Act and the Company’s constitution, the Company
called a general meeting for 12 December 2007 (“General Meeting�). A notice of
meeting was sent to all shareholders on 12 November 2007.
Following discussions between the Company and Mineralogy it was resolved that the
meeting was no longer necessary. The Corporations Act and the Company’s
constitution prevent the Company from cancelling the General Meeting and it must
still proceed as advised.
Given these circumstances, Mineralogy has irrevocably agreed that it will:
• Abstain from voting at the General Meeting (whether in person, by proxy or by
corporate representative); and
• Not attempt to provide a proxy form in respect of the General Meeting.
The Directors of Mineralogy have agreed to the content of this statement and
consented to its release to the ASX.
