Eldorado Gold Provides an Exploration Update on the Lower Triangle Deposit
VANCOUVER, BC - Eldorado Gold Corporation ("Eldorado" or the "Company") is pleased to provide results
of its exploration activities completed since Q4 2018 at the Lamaque Project in Quebec, Canada . These
results have successfully expanded high grade mineralization beyond the 2018 resource model in the lower
portion of the deposit as well as an expanded bulk stockwork zone below 1,250 metres.
Highlights*
• Multiple high grade step-out intersections at the Triangle Deposit significantly expand the resource
potential of the C7, C9, C9b, and C10 shear zones, including intercepts of:
o 3.85m at 19.33 g/t Au; 32.53 g/t Au uncapped (C7; TM-16-191M01)
o 9.30m at 10.72g/t Au (C7; TM-18-327W02)
o 5.30m at 12.22g/t Au; 17.23 g/t Au uncapped (C9b; TM-18-327W01)
• Large vein stockwork zones potentially amenable to bulk mining further defined in the lower Triangle
Deposit area, including:
o 64.50m @ 3.00 g/t Au; 6.38 g/t Au uncapped (zone below C9, TM-15-020W03M01)
• Step-out drilling at the Plug 4 Deposit expanded the depth extent of mineralization for an additional
500 vertical metres down-plunge of the previous resource
*All assays capped at 40.0 g/t Au unless otherwise noted.
George Burns, President and CEO of Eldorado Gold said, “Over the last 12 months our surface exploration
drilling at Lamaque has focused on better defining the resource potential in the less-explored lower portion
of the Triangle Deposit with a view to expa nding mineral resources in 2020 . At the same time our
underground drilling continues to focus on conversion of existing resources to reserves in the C5 and lower
C4 mineralized zones.”
“These exciting results significantly increase the resource potential of the lower Triangle Deposit, which now
shows continuity of mineralization to similar depths as the nearby historic Sigma mine. This asset continues
to underpin our vision of building a long-term business in the eastern Abitibi and growing value for our
shareholders.”
Triangle Deposit Exploration Summary
Exploration drilling at the Triangle Deposit from Q4 2018 to date targeted the area below the C5 ore zone at
depths of 1,000-1,800 metres from surface. Results shown here are based on 35,526 metres of diamond
drilling, of which 22,650 metres targeted the lower Triangle Deposit, with the remainder testing other zones
in the Sigma-Lamaque project area. This drilling was completed from surface platforms, with most holes at
the Triangle Deposit wedged from previous exploration drillholes.
High gold grades within this interval occur in both steep shear zone-hosted veins and in irregular networks
of extensional veins peripheral to the shear zones.
Mineralized shear zones in the lower deposit include C6, C7, C8, C8b, C9, C9b, and C10 as well as numerous
secondary splays either parallel to , or branching off , these primary structures (Figure 1) . Through this
2
interval, t he main shear zones steepen gradually with depth, accompanied by an increase in density of
mineralized secondary splays and extensional vein networks. At depth, the combination of the steep shear
zones and extensional vein networks represent potential bulk mining targets, similar to areas mined at the
nearby historic Lamaque Mine. Both styles of mineralization are localized within and peripheral to diorite
plugs, the most significant of which is the Triangle diorite.

outline of the Triangle diorite, and mineralized zones referred to in this news release.
Assays have been received from 17 drillholes completed in the lower Triangle Deposit since early Q4 2018,
all of which intersected significant zones of mineralization. Table 1 (below) lists significant intercepts ,
including estimated true widths where possible and both actual assay composites and values calculated with
a 40 g/t cap applied to individual assays. References to intercepts in the text represe nt actual drillhole
lengths while those on figures 2-4 are true widths of mineralized zones.
Shear Zone Hosted Mineralization
The most continuous and consistently mineralized shear zones in the lower Triangle deposit include C7, C9,
C9b, and C10. These shear zones are similar in character to the main ore-bearing shear zones in the upper
Triangle Deposit (C1-C5), with strongly foliated wall rock margins overprinted by sericite -albite-carbonate-

pyrite alteration and enclosing variably deformed quartz-carbonate-tourmaline veins. Gold is contained
within both the vein and deformed wall rock.
C7: The C7 mineralized zone is hosted within a large ductile -brittle shear zone, which offset s the Triangle
intrusion approximately 100m. Drilling to date has delineated the C7 mineralized zone over a strike length
of approximately 600 metres and a dip extent of 500 metres. The thickness of the shear zone in this area
measures up to 20 metres.
Significant new drill intercepts from C7 include:
• 3.85m @ 19.33 g/t Au; 32.53 g/t Au uncapped (TM-16-191M01)
• 3.08m @ 10.93 g/t Au (TM-18-321AW04M02)
• 9.30m @ 10.72 g/t Au (TM-18-327W02)
• 5.60m @ 9.40 g/t Au (TM18-327W03)
All of these intercepts are from the easternmost area tested on C7, well outside of the 201 8 inferred
resource outline (Figure 2). These are some of the best grades and thicknesses obtained to date on C7, and
the zone remains open further to the east. Current drilling is testing the updip extension of the C7 Zone,
above where thick, high grade intercepts have been defined at elevations roughly equivalent to the lower
limit of the C5 zone resource.

contours, Au capped at 40 g/t.1
1 Labeled piercing points are limited to new intercepts exceeding 10.0 g/t x m. For all zones, best new results are from the eastern portion of the
zone, well outside the limits of the current inferred resource. The mineralized zones remain open to the east outside of these new intercepts.

C9/C9b/C10: The C9, C9b, and C10 shear zones collectively define a tabular, steeply south dipping to
subvertical corridor ranging from 70 metres to over 120 metres wide. The C10 shear zone is a ductile-brittle
fault zone similar to the C7 zone, and displaces the Triangle diorite by at least 100m. This corridor is steeper
than the shear zones above, and contains numerous splay structures and extension vein arrays defining large
zones of veining and alteration. High gold grades in this corridor occur within the principa l shear zones, as
well as in secondary splays and extensional vein arrays flanking shear-hosted zones, and are concentrated
near the contacts of and within diorite intrusions. Drilling to date has tested this structural corridor over a
strike length of approximately 600 metres and a vertical extent of 500 metres . Within the drilled area, C9b
and C10 show best continuity and grade of shear-hosted mineralization.
Significant new drill intercepts from C9, C9b, and C10 include:
• 6.00m @ 10.11 g/t Au (C9; TM-15-020W01)
• 3.40m @ 13.47 g/t Au (C9, TM-18-321AW05)
• 4.80m @ 5.06 g/t Au (C9, TM-18-327W01)
• 5.30m @ 17.23 g/t Au (C9b, TM-18-327W01)
• 3.40m @ 10.32 g/t Au (C9b, TM-18-327W03)
• 6.60m @ 4.89 g/t Au (C10, TM-15-020W02)
• 4.00m @ 10.17 g/t Au (C10, TM-16-220W05)
Similar to C7, most of the best grades and thicknesses were obtained from the easternmost drillholes testing
the system, outside of the current inferred resource . The mineralized shear zones remain open updip and
to the east along a shallow ly east-plunging axis (Figures 3 and 4), parallel to the intersection of the shear
zones and the Triangle diorite.

C6, C8, and associated splays: The C6 and C8 shear zones have both been defined through drilling over a
vertical extent of approximately 500m. Although both have local wide, high grade intercepts, drilling
completed to date has not established the level of grade continuity found in the C7, C9, C9b, C10, and upper
Triangle shear zones. However, numerous high grade intervals occur within secondary splays associated
with C6, C8, and the deep er shear zones. Where their orientation is constrained, these secondary splays
tend to have shallower dips than the main shear zones. The splays are most abundant near contacts of the
Triangle diorite and other intrusions. Significant new intercepts from C6, C8, and these splays include:
• 4.30m @ 16.63 g/t Au; 20.62 g/t Au uncapped (splay between C8 and C9, TM-15-020W01)
• 2.40m @ 23.76 g/t Au; 78.62 g/t Au uncapped (splay between C9b and C10, TM15-020W03M01)
• 1.70m @ 14.75 g/t Au; 1,038.70 g/t Au uncapped (splay below C10, TM15-020W03M01)
• 4.70m @ 9.57 g/t Au (splay between C9b and C10, TM15-020W04)
• 5.25m @ 9.96 g/t Au; 13.14 g/t Au uncapped (C8, TM-15-053)
• 4.30m @ 21.24 g/t Au; 37.74 g/t Au uncapped (splay between C9b and C10, TM-18-321AW05)
• 3.50m @ 17.26 g/t Au; 22.03 g/t Au uncapped (splay between C9 and C9b, TM-18-327W01)
• 2.30m @ 17.07 g/t Au; 22.19 g/t Au uncapped (splay between C9 and C9b, TM-18-327W02)
Ongoing drilling of the lower Triangle Deposit will better define continuity of mineralized zones h osted by
these shear zones and splays.
Stockwork zones: Stockwork zones in the Triangle Deposit represent vein networks composed of shear-
hosted and extensional veins with associated alteration and mineralization , which combine to form over
10% of the rock volume. These zones vary in size and shape, but can have longest dimensions of over 100m
6
(Figure 5) . They are similar in structural and minera lization style to the stockwork zones mined at the
historical Lamaque Mine, located 2.5km to the northwest of the Triangle Deposit. Recent stockwork zone
intercepts include:
• 54.00m @ 3.98 g/t Au; 4.78 g/t Au uncapped (zone between C9 and C9B, TM-18-327W01 )
• 64.50m @ 3.00 g/t Au; 6.38 g/t Au uncapped (zone below C9, TM-15-020W03M01)
• 52.80m @ 2.67 g/t Au; 4.94 g/t Au uncapped (zone below C10, TM-15-020W04)
• 37.5m @ 3.62 g/t Au; 4.37 g/t Au uncapped (TM-18-327W03)
Stockwork zones are best developed within and near the Triangle diorite. Extensional veins within them are
mainly subhorizontal to gently dipping, while the shear and shear-extensional veins dip steeply south.
Figure 5: Cross section through the C9/C9b/C10 structural corridor showing extent of stockwork mineralization and intercepts in
several drillholes highlighted in this news release (in red text). Stockwork vein networks, consisting of both shear-hosted veins
and extension veins, are focused within and adjacent to the lower part of the Triangle diorite, which forms a discrete body in the
footwall to the C10 shear zone. Mineralization remains open down-plunge and along strike.
Plug #4 Deposit Exploration Update
Two new drillholes were completed at the Plug 4 deposit, testing for continuity of mineralization below the
extent of the previous drilling. Both drillholes intersected wide mineralized stockwork zones featuring shear
veins flanked by extension vein arrays, similar in style and grade characteristics to those forming the main
deposit area. The host Plug 4 intrusion has now been tested to a depth of 1, 500m from surface, and
mineralization remains open down plunge.
