Arianne Resources Inc./Havre Nord Project: A Pegmatite Returns Up to 0.43% U3O8

SAGUENAY, QUEBEC--(Marketwire - Oct. 24, 2007) - Arianne Resources Inc. (Arianne) (TSX VENTURE:DAR) (FRANKFURT:JE9) (OTCBB:DARUF)and Exploration Azimut (Azimut) announced on September 27, 2007 the discovery of an important uranium target on the Havre Nord uranium project on Quebec's North Shore area. Assay results from this target just returned up to 0.43% U3O8. Furthermore, grades from Rare Earth Materials (REM) are also exceptionally high. The economic value of the combined REM could even be worth double the value of the uranium from the pegmatite.

Uranium content: The pegmatite is 5 meters thick and was sampled in the most representative way possible. The combined U-Y-REM grades are concentrated in the centre of the pegmatite. A typical section from the edge to the centre of the pegmatite returned grades as shown in the table below (from #263809 on the edge to #263821 in the centre). The assay results for uranium returned grades up to 2,030, 3,160 and 3,670 ppm uranium or respectively 0.24%, 0.37% and 0.43% of U3O8 or also 5.3, 8.1 and 9.5 lbs/mt of uranium oxyde.

REM content: Two of the three samples that returned high uranium grades, returned grades superior to the detection limit for Gd, La, Nd, Pr, Sm. The dollar value of the combined Rare Earths Materials could be well over $1,000 per tonne of pegmatite. An extensive mineralogic study will be done on representative samples of the pegmatite in order to evaluate the economical potential of the REM.

The assays were performed at ALS-Chemex labs with the ICP-MS method. The code number of the assay is ME-MS81 (refer to the lab's website for additional information).

Perspectives: The pegmatite is located within a high uranium content zone according to the helicopter radiometric map. Exploration was done for only one day in this area in the summer of 2007. A team is currently on site in order to evaluate the best way to rapidly develop this discovery.

About REM: Rare Earth Materials are a group of 17 elements of which yttrium, scandium and the lanthanides series of the periodic table of elements. With their unique and various catalytic, magnetic and optic properties, REM are used in a growing number of applications, whether individually or mixed. They are critical and strategic parts of many digital technology applications as well as applications in energy efficiency and in the reduction of greenhouse gas emissions.

Currently, 97% of the REM world supply comes from China. China recently announced a reduction in the exports of rare earth materials coming out of their mines. This decision will considerably reduce the supply for buyers outside of China while world demand is in full growth. The main consumers of rare earths are in South-East Asia (Japan, Korea, Thailand, China) and in the USA. The United States used to be the largest consumer of rare earths, about 27% of the world's total. However, in recent years, China became the first world consumer, exceeding the American consumption. The United States currently imports nearly 100% of their needs in REM, and the American market for rare earths is valued at more than 1 billion US dollars per year. It becomes safe and critical to produce resources outside of China.
