MONTRÉAL, QUÉBEC--(Marketwired - Nov. 8, 2016) - Mason Graphite Inc. ("Mason Graphite" or the "Company") (TSX VENTURE:LLG)(OTCQX:MGPHF) is pleased to announce that, as originally mentioned in its press releases issued on September 6^th and 27^th, 2016, the Company has completed an additional equity investment of $1,000,000 in Group NanoXplore Inc. (''NanoXplore").

After its initial investment in February 2014 and after giving effect to this investment, Mason Graphite's equity interest in NanoXplore now stands at 32.5% of the new total amount of shares outstanding. Mason Graphite remains NanoXplore's sole graphite supplier and acts as commercialisation agent.

Benoît Gascon, President and CEO of Mason Graphite, commented: "We have been very happy with the business progression of NanoXplore and its industrialization strategy which focuses on markets with large potential like all the polymers applications among others. All current users of graphite being potential users of graphene, this partnership aligns perfectly with our commercial strategy."

More information about this financing is available in a press release issued by NanoXplore in which Soroush Nazarpour, President and CEO of NanoXplore, commented: "NanoXplore will use the funds raised to scale production of graphene from 4 to 64 metric tonnes per year, and to help its customers develop new and innovative products using graphene-enhanced polymers." NanoXplore recently increased the footprint of its manufacturing facility, which was commissioned in 2015, from 8,500 sq. foot to 24,000 sq. foot.

Further to the closing of the bought deal private placement offering announced on September 27^th, 2016, Mason Graphite reports that insiders of Mason Graphite purchased an aggregate of 17,590,909 common shares. Accordingly, the private placement is a "related party transaction" within the meaning of Regulation 61-101 respecting Protection of Minority Security Holders in Special Transactions ("Regulation 61-101"). Since the fair market value of the consideration for the common shares issued to insiders did not exceed 25% of Mason Graphite's market capitalization, Mason Graphite relied on the exemptions from the valuation and minority shareholder approval requirements of Regulation 61-101 contained in Sections 5.5(a) and 5.7(1)(a) of Regulation 61-101.
