Murchison United NL: Uranium Drilling to Commence in Mauritania West Africa

- Initial 4,000m RC drilling program to commence in Bir En Nar region of Mauritania.

- Drilling scheduled to commence in the first half of November 2007.

- Drilling to follow up previously reported sampling results of up to 9,500ppm Uranium.

PERTH, WESTERN AUSTRALIA--(Marketwire - Oct. 15, 2007) - Murchison United NL (ASX:MUR)(AIM:MUU) is pleased to
announce that it is preparing to commence its second uranium drilling program in West Africa, focusing on one
of its key Exploration Licences in the Bir En Nar region of the Republic of Mauritania.

The forthcoming drilling represents the first drilling program to be conducted by Murchison United within the
extensive portfolio of uranium interests it has secured in Mauritania. It follows the successful completion of
its maiden drilling program earlier this year at the Firawa prospect in Guinea, which returned encouraging
initial results.

The drilling program at Bir En Nar is scheduled to commence in the first half of November 2007, and will
comprise 40 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 Bir En Nar region, where episyenite
samples collected during previous field reconnaissance visits have returned assays of up to 9,500ppm U.

The Company's original intention was to conduct a program of diamond drilling at Bir En Nar, however this was
changed due to difficulties in obtaining adequate water supplies.

Samples will be taken every metre for multi-element analysis in Canada and the Company will release the results
of the drilling 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. 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 Bir En Nar 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.
