Arianne Resources Inc./Final NI 43-101 Lac-a-Paul Pre-Feasibility Study Update Filed on SEDAR

Marketwired

SAGUENAY, QUEBEC--(Marketwire - July 31, 2012) - Ressources d'Arianne Inc. (the "Company" or "Arianne") (DAN.V)(JE9N.F)(DRRSF) is pleased to announce that the final NI 43-101 compliant report on its Pre-Feasibility Study Update (PFSU) has been completed by Met-Chem Canada and posted on SEDAR as of July 16, 2012. The final report confirms the initial findings reported on May 30, that a 3 million t/yr phosphate concentrate mine production scenario will generate an NPV8% close to $1 Billion ($985 million), a 23.2% IRR and a 3.9 year capital payback on a pre-tax basis.

The Company highlights the fact that this new economic model does not include resource estimates for the additional mineralization identified by drilling programs completed since last fall (see press releases in December 2011 and March 2012). That drilling confirmed the increased strike length of Paul Zone mineralization from 1.3 km to in excess of 2.5 km. Because results from that drilling were unknown at the start of this work, only resources calculated in November 2011 were used for the final PFSU. A new resource calculation will be completed as part of the upcoming Bankable Feasibility Study.

Highlights of the Pre-Feasibility Study Update ($US)

-- Measured & Indicated resources remain at 348 million tonnes @ 6.50% P2O5

-- Additional Inferred resources of 114 million tonnes @ 5.46% P2O5 are not

included in the Study

-- Combined Paul and Manouane proven and probable Mineral Reserves remain

at 307 million tonnes, with average grade of 6.59% P2O5 and average

stripping ratio of 0.83 (Cut-off grade of 2.43% P2O5)

-- Annual production will average 3 million tonnes of 38% P2O5 apatite

concentrate with low impurities

-- 17 year mine life at 50,000 tonnes ore/day production rate with average

mill recovery of 90%

-- Average concentrate price of $175/tonne FOB rail

-- Cash operating cost $80/tonne concentrate mine site ($90/tonne FOB rail)

-- Total Direct CAPEX Cost: $583.3 million

-- Indirect CAPEX Cost: $136.1 million and Contingency: $94.5 million

-- Total Initial CAPEX: $813.9 million

-- Pre-tax IRR: 23.2%

Bernard Lapointe, CEO, commented: "We are pleased that Met-Chem has confirmed the economic viability of the 3 million mt/yr project in its final NI 43-101 compliant report. Our Bankable Feasibility Study will be based upon this production scenario, which will include a new resource calculation that we expect will support a mine life expectancy of 25 years minimum."

Forward-looking information includes, but is not limited to, statements with respect to estimated mineral resources, anticipated effect of the completed drill results on the Project, timing of a feasibility study, and timing and expectations of future work programs. Often, but not always, forward-looking information can be identified by the use of words such as "plans", "expects, "is expected", "budget", "scheduled", "estimates", forecasts", "intends", "anticipates", or "believes", or the negatives thereof or variations of such words and phrases or statements that certain actions, events or results "may", "could", "would", "might", or "will" be taken, occur or be achieved.

CAUTIONARY NOTE TO US READERS

The SEC allows mining companies, in their filings with the SEC to disclose only those mineral deposits they can economically and legally extract or produce. Accordingly, information contained in this News Release regarding our mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations of the Commission there under.

In particular, this News Release uses the term "indicated" resources. U.S. readers are cautioned that while that term is recognized and required by Canadian regulations, the SEC does not recognize it. U.S. investors are cautioned not to assume that any part or all of mineral deposits in this category will ever be converted into mineral reserves.

This News Release also uses the term "inferred" resources. U.S readers are cautioned that while this term is recognized and required by Canadian regulations, the SEC does not recognize it. "Inferred resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. U.S. readers are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
