MONTREAL, QUEBEC--(Marketwired - June 6, 2017) - Mason Graphite Inc. ("Mason Graphite" or the "Company") (TSX VENTURE:LLG)(OTCQX:MGPHF) is pleased to announce material progress in its permitting process related to the Lac Guéret project with the acceptance (la "recevabilité") of its Environmental Impact Study (''EIS") by the Minister of Sustainable Development, Environment, and the Fight against Climate Change ("MDDELCC"). The EIS, originally filed in November 2015, will now be rendered public in its complete form. A summary was presented to the hosting populations and made publicly available in June 2016, summary on which they provided questions and comments which were taken into consideration in the final version of the EIS. 

From a process standpoint, the file now progresses towards the Bureau d'audiences publiques sur l'environnement ("BAPE") (public hearing office on the environment). This government body will make available to the hosting populations the EIS in its entirety for a prescribed period of 45 days, at the end of which the Minister will receive a factual report on the conduct of the information and consultation period. The Minister will then determine whether a formal public hearing process is required prior to the determination of the project's eligibility to receive its final general certificate of authorization.

Mason Graphite has already conducted, in the last 4 years and more actively in the last 18 months, several general and focused information meetings with the active participation of the communities of Baie-Comeau and Pessamit. Based on those interactions, Mason Graphite indicates that the local support seems to be positive. Therefore, the timeline triggered by this milestone should allow Mason Graphite to achieve its goal of commencing construction later this year. The 45-day information period will commence on June 13th.

Benoît Gascon, President and CEO of Mason Graphite, commented: "On behalf of everyone at the Company, I would like to thank everyone involved at the MDDELCC for their work and continued assistance throughout this process. The Company would also like to thank the communities of Baie-Comeau and Pessamit for their engaged and active participation which makes possible the social engagement necessary to sustainable development. The Company also recognizes the support provided by the Société du Plan Nord and the RMBMU (Réserve mondiale de la biosphère de Manicouagan-Uapishka)."

UPDATE ON THE CONSTRUCTION OF A ROAD SEGMENT TO MASON GRAPHITE'S SITE IN BAIE-COMEAU

In a prior communication, Mason Graphite indicated that a contract had been awarded by the City of Baie-Comeau for the construction of a 1.2 km road segment, along with all related services, linking the Company's plant site, in the Industrial Park Jean-Noël-Tessier, to the neighboring highway. The Company is pleased to report that significant progress has been made such that access to the plant site should be completed before Mason Graphite begins construction. This road segment is Government funded and its construction has been specifically advanced for Mason Graphite.
