· Drilling commenced on Saturday 8 December 2007 at Bir En Nar in the
Zednes region of Mauritania, with downhole logging and assay results to
be released to the market as they become available.
· Initial RC drilling program aims to drill 40 holes of approximately 100m

Murchison United NL (ASX: MUR, AIM: MUU) is pleased to announce that drilling has
commenced on its second uranium drilling program in West Africa, focusing on one of its
key Exploration Licences at Bir En Nar in the Zednes region of the Republic of
Mauritania.
The current drilling program is the first drilling undertaken by Murchison United within
its extensive portfolio of uranium interests in Mauritania. It follows the successful
completion of the Company’s maiden drilling program earlier this year at the Firawa
prospect in Guinea, which returned encouraging initial results.
The drilling program at the Company’s prospect in the Bir En Nar area will comprise of
40 Reverse Circulation (RC) drill holes to an average depth of 100m per hole, for a total
of 4,000 metres of drilling. The drilling will focus on one of the Company’s southernmost
licences in the Zednes region, where episyenite samples collected during previous field
reconnaissance visits have returned assays of up to 9,500ppm U.
Samples will be taken every metre for multi-element analysis in Canada. The Company
will release downhole logging and assay results to the market as they become available.
Figure 1 overleaf shows the planned drill-hole locations in relation to historical
exploration work undertaken in the region by Minatome Pty Ltd in the 1980’s. The map
also indicates locations where samples of greater than 2,000ppm U were collected
during previous field visits conducted by Murchison United.

Murchison currently holds six uranium exploration permits in Mauritania covering a total
area of 8,200km2, with additional permits under application. The permit areas are in
the north of the country near the town of Bir Moghrein and in the Zednes region. They
are contained within the Reguibat Shield, part of the West African Craton.
This significant uranium exploration opportunity was originally identified by the
Company's Technical Director, Mr Bosse Gustafsson, from a study commissioned by the
World Bank, and further refined from aeroradiometric data highlighting the areas’
prospectivity for uranium occurrences and follow up field reconnaissance visits.
