MONTREAL, Dec. 05, 2018 (GLOBE NEWSWIRE) -- Mason Graphite Inc. (“Mason Graphite” or the “Company”) (TSX.V: LLG; OTCQX: MGPHF) presents detailed updated economics for the Lac Guéret graphite project (the “Project”).

On October 25th, 2018, Mason Graphite communicated its new construction budget for the Project in its Corporate and Project update. This new budget is part of a full update of the economics of the Project (“Project Economics”).

Benoît Gascon, President and Chief Executive Officer of Mason Graphite, commented: “As we are completing the detailed engineering, have started receiving equipment and have begun pre-construction work at mine site, we have updated the economics of the project. This update demonstrates, once again, that our project remains financially very robust and is becoming a reality at the dawn of an imminent and unique growth period for natural graphite, driven by the Li-ion batteries and electric vehicles revolution, expected for many years. Furthermore, this does not take into account the potential returns of the value-added and Li-ion battery materials program, another very strong upside potential for our shareholders.”

The technical and financial data was prepared by GoldMinds Geoservices, BBA and Soutex and validated by Qualified Persons, all independent of Mason Graphite.

Project Economics Update Highlights

  • No change to the Mineral Resources;
  • No change to the Mineral Reserves;
  • No material changes to the Project scope (production capacity and process unchanged);
  • Updated Capital Expenditures (“CAPEX”), Operating Expenditures (“OPEX”) and Natural Graphite sale prices;
  • Updated NPV, IRR and Payback period.

Using the updated operating costs and updated natural graphite sale prices, GoldMinds Geoservices (“GMG”) verified that the Mineral Resources estimated in 2014 were still valid. Using a revised cut-off grade of 5.75% Cg, the pit constrained Mineral Resources (Measured + Indicated) are now estimated at 65,540,000 tonnes, a change of -0.25% compared to 2014. The average graphite grade remains unchanged at 17.2% Cg.

Total Measured + Indicated65,540,00017.2% Cg
Inferred17,613,00017.3% Cg

Since the Mineral Reserves were constrained by the duration of the economic analysis (25 years) and not the Mineral Resources, they remain unchanged at 4,741,000 tonnes (Proven + Probable) at 27.8% Cg.

The construction budget for the Project was prepared by the Mason Graphite construction team. The budget considers the “owner’s built” construction approach and integrates equipment orders, firm and budget quotes from suppliers and technical data made available through the detailed engineering progress.
