Leagold Increases Bermejal Underground Measured and Indicated Mineral Resources by 94% to 1.97 Million Ounces
Vancouver, October 16, 2017 – Leagold Mining Corporation (TSX:LMC; OTCQX:LMCNF) ("Leagold" or the "Company") reports an update of the Bermejal Underground mineral resource estimate containing Measured and Indicated resources of 9.9 million tonnes at a grade of 6.2 grams per tonne ("gpt") for 1.97 million ounces, plus Inferred resources of 4.8 million tonnes at a grade of 5.4 gpt for 0.82 million ounces (Table 1). The database used for the updated estimate includes an additional 62 drill holes (16 drilled in 2016 and 46 from the 2017 drill program), as compared to the mineral resource estimates as of December 31, 2016. The majority of the remaining 67 holes planned for the 2017 drill program are infill and will focus on upgrading additional Inferred resources to Indicated classification.
Neil Woodyer, CEO stated: "This updated resource estimate includes a 94% increase in the Measured and Indicated resources and underscores the magnitude of the oxide mineralization of the Bermejal Underground deposit. In addition to converting the previously estimated Inferred resources of 678 koz to mostly Indicated resources, the program has also added 820 koz to the new Inferred resource estimate (Figure 1). The exploration success at Bermejal Underground, which drives this resource update, also supports our development plan to expand Los Filos’ gold production rate. The ramp to access the Bermejal Underground deposit recently commenced and has advanced 27 metres as of October 13, 2017."

|Au Grade |
|Au Contained |
|Ag Grade |
|Measured and Indicated||9,939||6.15||1,966||22.13||7,072|
1 Effective date is August 31, 2017.
2 Mineral Resources are reported using a cut-off grade of 3.0 gpt and do not include recovery or dilution factors.
3 Tonnages are rounded to the nearest 1 kt, grades are rounded to two decimal places; rounding, as required by reporting guidelines, may result in apparent summation differences.

Available data for the resource estimate includes 505 drill holes totalling 195,261 metres. Drill hole spacing is roughly 35 metres for Indicated resources and less than 25 metres for Measured resources. The mineral resource was prepared in Datamine using dynamic anisotropy and ordinary kriging and interpolated into 3 metre x 3 metre x 3 metre blocks and reported at a 3 gpt Au cut-off. The mineral resource was prepared by Leagold and reviewed and validated by SRK (Gilles Arseneau, P.Geo.) as the Independent Qualified Person.
Resources were classified as Measured, if they were within 25 metres of three drill holes. Blocks were classified as Indicated, if they were within 50 metres of two drill holes. All other blocks within 100 metres of two drill holes were classified as Inferred.
The Bermejal Underground deposit has a central portion with a grade of 7.2 gpt and containing approximately 60% of the Measured and Indicated resources. This high-grade zone ranges from 20 to 60 metres wide. The eastern and western flanks of Bermejal Underground provide extensive areas of mineralization along the contact of the Bermejal intrusive with surrounding carbonate rocks. These areas have more moderate grades ranging from 4.1 to 5.3 gpt and widths that are from 3 to 25 metres.
The mineralization has been drill tested along approximately 1,600 metres along the strike of the intrusive contact and has a vertical depth extent of over 800 metres (Figures 2 and 3).
Bermejal Underground Expansion Project Update
Development of an exploration portal and ramp recently commenced (see news release dated September 25, 2017) and the ramp has advanced 27 metres as of October 13, 2017. The ramp will provide access to the eastern and central portions of the deposit and will enable additional exploration, allow collection of material for confirmatory metallurgical testwork for heap leaching, demonstrate the minability of Bermejal Underground, and advance the project towards declaration of reserves.
The Bermejal Underground drilling program is now over 67% complete with 37,672 metres drilled of the planned 56,000 metres (as of October 13, 2017). A total of 70 of the planned 113 holes have been drilled. The drilling program is expected to be completed within 2017 and the additional drill hole results will be incorporated in an updated resource estimate.
The Measured and Indicated mineral resources are part of the engineering and mine design work being conducted for Bermejal Underground and will form the basis of the mineral reserves which will be reported in Q1 2018. An updated site wide technical report by SRK will be submitted in Q2 2018.

Los Filos Mine employs industry standard drilling and sampling procedures. All exploration samples are sent to an ALS Global facility in Guadalajara for preparation and Vancouver for analyses by fire assay and ICP. A full quality control and assurance program and protocols are in place and are aligned with best practices including regular insertion of certified reference standards, blanks, and duplicates.
