SAGUENAY, QUEBEC - (June 30, 2015) - Arianne Phosphate (the "Company" or "Arianne"), a development-stage phosphate mining company, advancing the Lac à Paul project in Quebec's Saguenay-Lac-Saint-Jean region, is pleased to announce that its ongoing efforts to reduce the production cost of its high-purity phosphate concentrate have led to an additional $8 per tonne reduction in the Company's operating expense.

According to the Company's Feasibility Study ("FS") filed in October 2013, Arianne initially projected an FOB Port of Saguenay cost of US$93.70 per ton for its premium quality 39% P2O5 concentrate. Following the release of the Feasibility Study, the Company has launched numerous initiatives to improve the project economics with much of that effort targeted at reducing its operating costs. To date, the Company has announced an optimized mining plan to include additional resources it had proved up, as well as savings associated with a more streamlined metallurgical process. This subsequent reduction is a continuation of the Company's efforts to move the Lac à Paul project even lower on the cost curve.

"Our latest success in reducing our anticipated production costs is very encouraging and, when looked at through its entire process, represents a considerable savings over the projected life of mine," commented Jean-Sebastien David, Arianne's COO. "From the day we released our Feasibility Study, we have set out to advance development of Lac à Paul. In less than two years, we have expanded our resource, simplified our process to make a high-purity phosphate concentrate, concluded a power deal with Hydro-Québec and received an investment from the Government of Quebec. Once the project proceeds to production, our most recent studies support a production cost of approximately $80 per tonne of concentrate."

The Company recently signed a Cooperation Agreement with the First Nations and concluded its public hearings in order to receive final permitting for its Lac à Paul project. Going forward, Arianne will continue to explore other initiatives in order to optimize its project and further reduce its costs.

Changes in the management team

Dino Fuoco, Chief Financial Officer and Corporate Secretary, announced that he will be leaving the Company on July 3rd to return to private practice. The Board of Directors of Arianne wishes to thank Mr. Fuoco for his excellent contribution to the development of the Lac à Paul project and wishes him well.

In the interim, Mr. Fuoco's role will be filled by James Cowley. Mr. Cowley, who currently sits on the Board of Arianne, is also a member of the audit committee. Mr. Cowley had previously served as President of Arianne from August of 2011 until August of 2014.
