          Release of Information on Mauritania Relevant to the Company



ROC Oil Company Limited a partner in the Mauritania PSC A and B Joint Ventures,
released the following information summarising the results of drilling offshore
Mauritania to the Australian Stock Exchange earlier today:



'The four wells drilled offshore Mauritania during the last 16 months have
yielded very encouraging results. All four wells have had a large exploration
element and three of them were, in fact, pure exploration wells, two of which
discovered potentially commercial hydrocarbons. All four wells encountered
measurable hydrocarbons, proving separate gross hydrocarbon columns of 9 metres,
90 metres, 94 metres and 133 metres. These drilling results are quite remarkable
for a previously undrilled, frontier area and they certainly highlight the
petroleum potential of the region. However, more time and many more wells will
be required before the total regional potential can be quantified reliably.

The results from the Chinguetti-4-2 well, the step-out exploration well on the
northern side of the Chinguetti structure, are still being interpreted. Current
interpretation suggests that the well drilled through two main channel sands
within the previously reported 94 metre gross oil column. The majority of the
net pay in the well, mainly in the lower of the two channel sequences, is
interpreted as having excellent reservoir quality.

Separately, in the lower part of the Chinguetti-4-2 well, below the oil-bearing
interval, additional channel sands with a combined net thickness in the order of
25 metres were encountered. These sands also have good to excellent reservoir
qualities and, although water-wet in Chinguetti-4-2, they are expected to be
oil-bearing higher up the structure.

The depositional environment of channel sands is such that individual sand
packages will typically thicken or thin away from any single data point. Because
of this, the individual net pay intervals in such wells should always be viewed
within the context of the overall extent of the channel sand sequence, which is
largely reflected by the gross hydrocarbon column and the connectivity of the
sands within that system. When considering net reservoir thicknesses, it should
also be borne in mind that sand bodies associated with salt domes, such as those
encountered offshore Mauritania, may thicken down dip from the high points of
the structure.

The three wells, which have encountered substantial gross hydrocarbon columns
(90 metres to 133 metres) offshore Mauritania, collectively demonstrate net
reservoir pay sands which represent between 25% and to 40% of the respective
gross hydrocarbon columns.

In general terms, the thickness of the net reservoir sand in the Chinguetti-1
discovery well is the same order of magnitude as that in the Chinguetti-4-2
well, although the 3D seismic suggests that the sand thickens down dip from the
discovery well.

Evaluation of the most recent well, the Chinguetti-4-3 exploration well, drilled
on the Banda Prospect is continuing. Preliminary indications suggest that the
percentage of gross hydrocarbon column which is represented as net reservoir
sand in the well is at the high end of the 25% to 40% range quoted above.

There is no obvious oil-water contact in the Chinguetti-4-3 (Banda) well, where
there is almost 60 metres of, essentially, non-reservoir rock between the
highest known water and lowest known oil. Therefore, it is the extrapolation of
pressure data obtained while logging which implies that the gross oil column in
the well is in the order of 23 metres, as reported to ASX earlier this week.
Until additional subsurface information is acquired, this represents the most
accurate available estimate of the thickness of the oil leg at the Banda
location, but this estimate may change as and when more information becomes
available.'

The Chinguetti-4-4 appraisal well is due to spud today.  Fusion will continue to
make routine weekly progress reports and will provide a summary of the results
of the drilling campaign to date once operations have been completed.

Fusion has a 3% interest in PSC A and a 6% interest in PSC B.

Alan Stein, Managing Director, comments:

'It will take some time to fully evaluate information from the current drilling
campaign, however preliminary results from the exploration wells provide clear
encouragement regarding the commercial value of this project.  In addition, the
forthcoming appraisal well (Chinguetti-4-4) to the original Chinguetti-1
discovery will provide critical information for continuing development studies.'
