RE:RE:RE:the largest graphite mining project in the world The Lac Guret project is 500,000 tonnes of graphite concentrate per year. ($1500 per ton). This production is entirely intended for the anode material ($11,540 per ton). 500,000 tons x $11,540 per ton of anode material x 24 years = $138 billion. This is the gross value of the Lac Guret deposit. 50-50 LLG-NOU. Mason is made a royalty company. So the costs will be very low for Mason.
