Gran Colombia GOLD Announces Multiple High Grade Drill Results from Its 2017 Infill Drilling Program at Its Providencia MINE IN Segovia
NEWS RELEASE
GRAN COLOMBIA GOLD ANNOUNCES MULTIPLE HIGH GRADE DRILL RESULTS FROM ITS 2017
INFILL DRILLING PROGRAM AT ITS PROVIDENCIA MINE IN SEGOVIA
TORONTO, CANADA, Monday, September 18, 2017 – Gran Colombia Gold Corp. (TSX: GCM) announced
today the assay results from the ongoing 2017 diamond infill drilling program at its Providencia underground
gold mine at its Segovia Operations.
Infill drilling at Providencia was aimed to further delineate one of the main high-grade orebodies on which
sparse previous surface drilling had intersected high gold grades. Multiple high gold grades generated from
19 drill holes (1,119 metres) drilled from underground in the 2017 drilling program were intersected on the
main vein system with maximum grades of 649.1 g/t Au over 0.39 metres and 249.3g/t Ag over 0.95 metres.
Serafino Iacono, Executive Co -Chairman of Gran Colombia , commented: "We are pleased to report that
the assay results returned from the ongoing Providencia infill drilling program represent some of the highest
grades seen at Providencia so far, which further increases our confidence in the potential for adding new
resources to the mine and extending its mine life . The underground mine at Providencia is one of the
highest-grade mines in Colombia and it continues to contribute to our production growth and free cash flow
generation from our Segovia Operations."
Segovia Drilling Highlights and Key Intercepts
Drilling results from the Providencia m ine confirm the previously modelled high -grade nature, strong
down-plunge continuity of gold mineralization and the thickness of one of the main orebodies currently
in production on Level 14.
This orebody remains open at depth and we believe it offers the potential for additional resource growth.
The high-grade gold mineralized intercepts associated to this main orebody confirm the higher grade
mineralization at depth, which could have a positive impact on the increase of the mining production at
Providencia.
The Providencia drill program continues to increase the confidence in the geological model of the
orebodies through increased drill density.
The drilling program focused on providing increased definition and confidence in the near -term mine
operation and includes the following key intercepts:

intersection lengths do not represent true widths. Sample grades over 8.0 g/t Au reported. Grades are for quartz vein
intersections and are length-weighted composites. The length is the sample length and is not necessarily the true width of
the vein. All gold and silver grades are uncut and are not diluted to a minimum mining width. Abbreviations: HW: hanging

Quality Assurance and Quality Control
The samples were prepared and assayed by SGS Laboratories Ltd (ISO 9001:2008) at their laboratory in
Medellin, Colombia. Gold was assayed by fire assay with atomic absorption spectrophotometer (“ AAS”)
finish. Samples over 10 g/t gold were re-assayed by fire assay with gravimetric finish. Silver was assayed
by aqua regia digestion and AAS finish. Blank , standard and duplicate samples were routinely inserted for
quality assurance and quality control.
