Mason Graphite Files an Amended Technical Report for its Lac Gueret Project

236 Days ago

MONTREAL, QUEBEC--(Marketwired - Feb 29, 2016) - Mason Graphite Inc. ("Mason Graphite" or the "Company") (TSX VENTURE:LLG)(OTCQX:MGPHF) reports that it has filed an amended technical report entitled "NI 43-101 Technical Report: Resources Update and Feasibility Study, Lac Guéret Graphite Project, Québec, Canada" which has been prepared pursuant to Canadian Securities Administrators' National Instrument 43-101; this updated version replaces the technical report filed by the Company on November 9th 2015.

Sections 1.9 and 15.3.6 have been modified to reflect the updated classification of the incremental tonnages contained within the pit design beyond the initial 25 years mine life of the Lac Guéret Graphite Project as "In-Pit Mineral Resources beyond Project Life of 25 years" instead of Mineral Reserves. These "In-Pit" Mineral Resources were included in the pit optimization study and are similar in quality and metallurgical response to the Mineral Reserves included in the 25 years pit design, but they have not been included in the economic analysis presented in the Feasibility Study as such analysis could not be reliably conducted for an extended period of time and because the cash flows generated beyond 25 years have little impact on the economic results of the Feasibility Study; therefore those "in-Pit" Mineral Resources cannot be classified as Mineral Reserves. However, no further drilling will be necessary to conduct the economic evaluation required to eventually classify In-Pit Mineral Resources as Mineral Reserves. Moreover, the overall In-Situ graphite tonnage, the tonnage and grade of the Mineral Resources, the economic analysis included in the Feasibility Study (including the IRR, the NPV and the other Feasibility Study Results Highlights included in the Press Release dated September 25, 2015) and the effective date of the technical report all remain unchanged.

The updated Mineral Reserves, the In-Pit Mineral Resources beyond the Project Life of 25 years and the Mineral Reserves as presented in the original technical report dated November 9, 2015 are presented below (totals may not add-up due to rounding).

In addition to the above noted changes, a new section entitled "Risks Specific to the Project" has been added, which summarizes the risks factors disclosed in the various sections of the technical report and provides an overview of the risk factors associated with the project related to health & safety, to environment, to technical and operational elements, to commercial, competition and demand, to social aspects as well as financial and legal elements.

The preparation of the technical report was directed by Mr. Jean L'Heureux, Eng., M. Eng., Executive Vice-President, Process Development. For further details, please access the Technical Report having an effective date of September 25th, 2015 and a re-issue date of February 29th, 2016 available on www.sedar.com under Mason Graphite's profile and on the Company's corporate website at www.masongraphite.com.

Cautionary Statements Regarding Mineral Reserves and Mineral Resource Estimates

The Mineral Reserves are the basis of the 25-year Mine Life of the Feasibility Study published on September 25th, 2015 and are not included in the "In-Pit" Measured and Indicated Mineral Resources of 58.1 Mt grading 16.3% Cg (which have an equivalent drilling definition). The Mineral Reserves and the "In-Pit" Mineral Resources are included in the total Measured and Indicated Mineral Resources of 65.7 Mt grading 17.2% Cg (19.1 Mt of Measured Resources grading 17.9% Cg and 46.6 Mt of Indicated Resources grading 16.9% Cg) that were reported in the Company's press release dated December 15th, 2014. The reference point for the Mineral Reserves estimate is the mill feed. Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability and were not included in the mine life or the economics of the Feasibility Study. Environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues may materially affect the estimate of Mineral Resources. The same issues would need to be considered when conducting an eventual economic evaluation in order to classify the In-Pit Mineral Resources as Mineral Reserves. In addition, there can be no assurance that Mineral Resources in a lower category may be converted to a higher category, or that Mineral Resources may be converted to Mineral Reserves.
