ARIANNE PHOSPHATE REPORTS CORPORATE AND FINANCIAL RESULTS FOR FIRST QUARTER 2018

Arianne Phosphate Inc. has released its financial results for the three-month period ended March 31, 2018. All amounts are in Canadian dollars unless noted.

"The first quarter of the year has been a very busy one for our company," said Brian Ostroff, chief executive officer of Arianne Phosphate. "Year to date, Arianne has made steady progress working with potential funders and partners for our project. As well, we are also seeing the recovery in phosphate prices from multiyear lows driving interest from potential offtakers. Ultimately, we believe that with so few new projects coming on stream, our strong economics and our safe geopolitical jurisdiction will all be very supportive in our mission to get the Lac a Paul project developed and unlock tremendous value for our investors and stakeholders."

Q1 2018 financial and operational highlights:

• In March, 2018, the company announced that it has received an investment from the government of Quebec by way of private placement of $1,407,000 into the common shares of Arianne. Under the terms of the offering, the company issued 2,333,333 units at a price of 63 cents per unit. Each unit comprised one common share and one-half of one common share purchase warrant. Each warrant entitles its holder to purchase one common share at a price of 85 cents per share until March 14, 2021.
• In March, 2018, the company announced the start of research and development work to integrate aluminum in the design of the trailer that will transport the phosphate concentrate from the Lac a Paul mine to the deepwater port that will be located in Sainte-Rose-du-Nord. The work will be done by the National Research Council of Canada (NRC) and Alcoa Innovation. In order to carry out this major work, Arianne will be able to rely on confirmed financial support from the Centre quebecois de recherche et de developpement de l'aluminium (CQRDA) and the Societe de la vallee de l'aluminium (SVA).
• In January, 2018, the company announced the extension on the term of 1,217,500 common share purchase warrants issued as part of a private placement which closed on July 29, 2013, for gross proceeds of $2,678,500. Each of the warrants, which were part of the units being issued, entitles its holder to purchase one common share of Arianne at an exercise price of $1.45 per common share until Jan. 27, 2018. Arianne has elected to extend the expiry date of the warrants to July 27, 2018. No other warrant terms were amended.

Highlights subsequent to quarter-end

In April, 2018, the company announced that it received a grant of $1.5-million from the Ministry of Energy and Natural Resources of Quebec. This funding has been provided as part of the government's plan to help advance the Quebec phosphate (apatite) sector. Arianne will be using this funding in support of its previously announced program to produce additional high-purity phosphate concentrate to fulfill demand from potential customers and to conduct further pilot-scale tests. The tests will be conducted at COREM (Research Consortium for the Treatment and Processing of Mineral Substances) in Quebec City, where the company conducted its previous pilot-scale tests, and materials will be sent to parties that have expressed a strong interest in pursuing some form of offtake and/or a strategic partnership with Arianne.

Financial summary

Arianne is a development-stage company and, as such, did not generate revenue or positive cash flow in Q1 2018. In the first quarter ended March 31, 2018, the company incurred net losses of $700,000 for the three-month period. This compares with a net loss of $800,000 for the three-month period of 2017.

Liquidity

At March 31, 2018, the company had $1.17-million cash on hand. These funds will be allocated toward general working capital and advancing development of Lac a Paul in 2018. Based on current spending estimates for future project development, Arianne will need additional financing in 2018.

Outlook

Through the rest of 2018, Arianne will be focused on the continuing advancement and development of its Lac a Paul project. Expected milestones include:

• Secure financing for construction and development of the Lac a Paul project;
• Continue optimization of the Lac a Paul project, including reducing cash operating production costs and capital expenses;
• Sign an impact and benefit agreement (IBA) with the first nations;
• Assist the Port of Saguenay in securing its environmental permitting from CEEA.

Arianne's management discussion and analysis (MD&A) and condensed consolidated interim financial statements for the three-month period ended March 31, 2018, are available on the company's website and on SEDAR.
