NMG released the results of a preliminary economic assessment for a new project covering Mason Graphite's Lac Gueret graphite deposit: the Uatnan Mining Project. The study demonstrates attractive economics for a targeted production of approximately 500,000 tonnes of graphite concentrate per annum over a 24-year life of mine, making it one of the World's largest graphite projects in development.

NMG's Management Team hosted an Investor Briefing for shareholders and analysts to review the details of the announcement.
