Arianne's Scoping Study Shows That an Exploitation on the Lac a Paul Deposits Would Be Very Profitable

SAGUENAY, QUEBEC--(Marketwire - Nov. 20, 2009) - Arianne Resources Inc. ("Arianne" or the "Company")(TSX VENTURE:DAN)(FRANKFURT:JE9N)(OTCBB:DRRSF) management is pleased to announce the first economic and profit estimates for the Lac a Paul phosphorus-titanium project. This property is 100 %-owned by Arianne and is located 200 km North of the town of Saguenay, Quebec, Canada.

The Scoping Study was done by IOS Services Geoscientifiques Inc. and is based on the inferred resource calculation previously provided by SGS Geostat Inc., in March 2009. The resource estimate was as follows, given a 2% P2O5 cut-off grade : (1)(2)(3)

- Paul Zone : 99.30 Million tons of inferred resources at 7.84 % P2O5 and 8.24 % TiO2

- Manouane Zone : 140.60 Million tons of inferred resources at 5.77 % P2O5 and 9.01 % TiO2

- Zone 2: 64.10 Million tons of inferred resources at 4.52 % P2O5 and 4.51 % TiO2

- Total of 3 Zones; 304 Million tons of inferred resources at 6.18 % P2O5 and 7.81 % TiO2

(1) The resource estimate can be found in the 43-101 technical report: Phosphate and Titanium resource estimation of the Lac a Paul property deposit, Saguenay-Lac-St-Jean Quebec Canada (Claude Duplessis, May 8, 2009).

(2) This resource estimate does not include the current drill holes on the Paul Zone which results will be released in early 2010.

(3) The Scoping Study mentioned herein is a preliminary evaluation. It targets inferred mineral resources that are too geologically speculative to infer economical considerations that would classify them into mineral reserves. It is therefore uncertain that this preliminary evaluation results into the expected outcome.

The following is a summary of the Scoping Study. The complete report will be filed on the Company's website (www.arianne-inc.com) and on SEDAR (www.sedar.com) in the next 45 days.

1- Base scenario

The economic study is only based on the first ten years of exploitation and therefore, only the resources of the Paul Zone were used for this preliminary evaluation. The recovery rate as well as the ore grades comes from the metallurgical tests performed by SGS Lakefield Research Ltd. An 85 % apatite recovery rate is used. An annual production of 2 million tons (Mt) of apatite concentrate is planned. Only the apatite concentrates are considered and no value is given to eventual titanium or iron concentrates.

Main characteristics of the apatite concentrate :



-----------------------------------------------
Element PAUL Zone
-----------------------------------------------
P2O5 % 39.9
-----------------------------------------------
P2O5 Recovery % 85
-----------------------------------------------
CaO % 52.5
-----------------------------------------------
SiO2 % 1.28
-----------------------------------------------
Fe2O3 % 1.98
-----------------------------------------------
TiO2 % 0.77
-----------------------------------------------
F % 1.77
-----------------------------------------------
U % less than 0.002
-----------------------------------------------
Cl g/t 1201
-----------------------------------------------
Hg g/t less than 0.3
-----------------------------------------------
Cd g/t less than 2
-----------------------------------------------
CaO/P2O5 1.32
-----------------------------------------------


2- Economic parameters

As of November 12, 2009, the sales price for phosphorus rocks grading between 65% and 75% BPL was US$90 for FOB (Free On Board) Morocco and US$116 for CFR (Cost & Freight) India. The phosphorus grade is usually expressed as tricalcic phosphorus and traditionally named BPL (Bone Phosphate Lime). The concentrate of the Paul Zone contains 39% P2O5 and grades more than 85% BPL. Since the priority target market is North America, a sales price of CAN$116 Free On Board Dolbeau (FOB Dolbeau) is viewed as realistic and conservative for the 85 % BPL Paul Zone concentrate. No premium is considered for the higher BPL grade included in the Paul Zone concentrate. It should be sold at a higher price since it contains more phosphorus. The US$/CAN$ exchange rate used is 0.93. A 1 % royalty is attached to the deposit.



3- Infrastructure and operation costs (CAN$)

Infrastructure costs of 320 M$

- Mine 51 M$
- Mining Plant 137 M$
- Preparation, tailings,
electricity, restauration 63 M$
- Transport trucks and landing stage 31 M$
- Miscellaneous and engineering (15%) 38 M$

Operation costs

- $/ton of mined ore 11.55
- $/ton of apatite concentrate (at the mine) 57.47
- $/ton of transportation of concentrate
to Dolbeau 13.60
- $/ton of apatite concentrate (at Dolbeau) 71.07

4- Economic value (CAN$)

- Sales price of the concentrate
in Dolbeau 116
- Profit per ton sold 44.93
- Discounted Net Present
Value at 3% (DNPV) 356,500,000
- Internal Rate of Return (IRR)
before taxes 19.07%


Mr. Bernard Lapointe, CEO of the Company comments : " The profitability of the project is obvious. It is mainly due to the availability of the existing roads for non standard transportation. These roads make the transportation of the apatite concentrate possible by truck to the Dolbeau-Mistassini train for less than $15/ton. The project will be presented November 25 at the QuebecExploration2009 convention at the Chateau Frontenac. The presentation will then be available on our website."
