Summary

During  the  Quarter,  Murchison continued to progress its portfolio of uranium exploration  projects  in
Guinea and Mauritania, West Africa, with the first drilling programme completed at the Firawa Prospect in
Guinea and planning well advanced for the next phase of exploration activity in Mauritania.

The Company also continued to evaluate new energy-related asset opportunities and to pursue programmes to
add value to its Australian copper project interests in Western Australia and North Queensland.
    

Republic of Guinea, West Africa

As  previously  announced, the Company completed an initial 2,050m RC drilling programme  at  its  Firawa
prospect  in  Guinea  during  May  2007.  Samples were forwarded to  Canada  for  multi-metal  analytical
processing. Assay results will be released to the market when available.

A drilling programme has been planned for the Company's Bohoduo prospect in Guinea, which is scheduled to
commence  after the end of the wet season. Subject to completion of negotiations to arrange access  to  a
drill rig, it is expected that drilling will commence during the next 2-3 months.


Republic of Mauritania, West Africa

The  Company was granted its sixth "Group 4" uranium exploration licence in Mauritania on 28  June  2007,
increasing its total ground position to 8,200km2.

There are still two applications for exploration permits pending.

During the quarter, a drilling programme was prepared for one of the Company's licences in the Bir En Nar
prospect.  Negotiations  are  in progress to arrange access to a drill rig and  it  is  anticipated  that
drilling will commence during the next 2 months.

The  Company is also in the process of establishing a permanent office in Nouakchott that will be staffed
by local geologists who will provide assistance to the Company's Technical Director.

Maroochydore Copper Project, Western Australia

During  the  quarter,  exploration budgets and work programmes were finalised with  the  Company's  Joint
Venture  partner,  Aditya Birla Minerals (ABY), for ongoing exploration activities  at  the  Maroochydore
Project.

A Reverse Circulation drilling programme comprising 13 holes for 1,500 metres commenced recently which is
designed in part to confirm the existing JORC compliant resource. All RC holes will be drilled within the
existing resource boundary.

Due  to the limited availability of the RC drill rig, it may not be possible to complete the full program
in  the  short  term.  A six-hole diamond drilling program has also been planned to further  confirm  the
resource and provide samples for metallurgical test work. The timing of this program is dependent on  rig
availability.

Maroochydore has a total estimated JORC compliant Indicated and Inferred Mineral Resource of  51  million
tonnes  at  a grade of 1% copper and 0.04% cobalt for 0.51 million tonnes of contained copper and  20,000
tonnes  contained cobalt (at a 0.5% Cu cut-off).  The Company's net attributable interest in this Mineral
Resource  is  25.5  mt  at  1% copper and 0.04% cobalt for 0.25 mt contained  copper  and  10,000  tonnes
contained cobalt.


Millenium Leases, Cloncurry - Queensland Australia.

The Company has prepared a drilling programme for the Millenium leases, which will be implemented as soon
as practicable now that funding has been secured through the Company's recent share placement.

The "Millenium" mining leases (ML's 3512, 2761, 2762, 7506 and 7507) are located some 35 kilometres north-
west  of  Cloncurry in north-west Queensland, Australia. The five adjacent leases include the  historical
"Federal"  copper mine and cover an area approximately 3.5 kilometres long and 500 metres wide  extending
in a northerly direction.


Corporate

On  7  May  2007,  a  proposed  share  placement was announced to secure  additional  funds  to  progress
Murchison's exploration activities. The first tranche of 40,819,165 shares at A$0.11 was issued on 7 June
2007.  A  general  meeting held in Perth on 13 July 2007 ratified the first tranche  and  authorised  the
Company to issue a further 19,180,835 shares.

The second tranche of the placement was completed on 17 July 2007 with the allotment of 26,852,366 shares
at  A$0.11. A total of A$7.4 million was raised, placing the company in a strong position to aggressively
pursue its exploration activities.


Other

Consistent  with  its  core focus on energy assets, Murchison continues to consider other  energy-related
resource  opportunities,  both in Australia and overseas. Discussions to date are  preliminary  and  non-
binding. If and when any proposals become binding, relevant announcements will be released.

Notes

1     The  quarterly  report provides a basis for informing the market how the entity's  activities  have
      been  financed  for  the past quarter and the effect on its cash position.  An  entity  wanting  to
      disclose  additional  information is encouraged to do so, in a  note  or  notes  attached  to  this
      report.

2     The  "Nature  of interest" (items 6.1 and 6.2) includes options in respect of interests  in  mining
      tenements acquired, exercised or lapsed during the reporting period.  If the entity is involved  in
      a  joint  venture  agreement and there are conditions precedent, which will change  its  percentage
      interest  in a mining tenement, it should disclose the change of percentage interest and conditions
      precedent in the list required for items 6.1 and 6.2.

3     Issued  and quoted securities  The issue price and amount paid up is not required in items 7.1  and
