Leagold Mining Corporation announced an increase of the Proven and Probable mineral reserves (P&P reserves) at the Los Filos open pit to 40.5 million tonnes grading 0.60 g/t containing 780 thousand ounces (koz) of gold as of October 31, 2018. This represents a 122% increase over the December 31, 2017 estimate of 351 koz. After accounting for mining depletion of 99 koz from January 1 to October 31, 2018, the total addition to the Los Filos open pit P&P reserves is 528 koz. This reserve update does not reflect changes to the Bermejal open pit or Los Filos underground mining areas, or potential additions from the Bermejal underground deposit. The additional contribution from the Bermejal underground expansion project cannot yet be reported as a mineral reserve until feasibility level studies are completed and an integrated site- wide mine plan is finalized. A site-wide independent technical report which will now be required is under way and will be available by year-end. The report will incorporate this Los Filos open pit mineral reserve update within a new site-wide production plan, including contributions from the Bermejal underground, Bermejal open pit, and Los Filos underground mine. Technical Disclosure: The technical disclosure included in this news release was reviewed and approved by Rodolfo Balderrama Neder, Mine Operations Manager of Administración Los Filos, S.A.P.I de C.V., a wholly owned subsidiary of the Company. Mr. Balderrama Neder is a Qualified Person as defined in NI 43-101. For a description of the key assumptions, parameters and methods used to estimate mineral reserves and resources at Los Filos, as well as data verification procedures and a general discussion of the extent to which the estimates of scientific and technical information may be affected by any known legal, political or other relevant factors relating to the potential development of the mineral resources or mineral reserves.
