Eldorado Gold Provides an Exploration Update on the Lower Triangle Deposit

VANCOUVER, Sept. 05, 2019 - Eldorado Gold Corp. ("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:
  • 3.85m at 19.33 g/t Au; 32.53 g/t Au uncapped (C7; TM-16-191M01)
  • 9.30m at 10.72g/t Au (C7; TM-18-327W02)
  • 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:
  • 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 expanding 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 interval, the 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.

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 represent 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 offsets 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 2018 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.

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. https://www.globenewswire.com/NewsRoom/AttachmentNg/0610e7aa-0719-49ce-a524-e890c3a8f26c

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 principal 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 shallowly east-plunging axis (Figures 3 and 4), parallel to the intersection of the shear zones and the Triangle diorite.

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. https://www.globenewswire.com/NewsRoom/AttachmentNg/a035a63e-375a-40dd-89f4-a36ac8260ea0

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.

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 deeper 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 hosted 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 (Figure 5). They are similar in structural and mineralization 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. https://www.globenewswire.com/NewsRoom/AttachmentNg/b84055cc-47a9-438f-a0e5-3f229e3a73e6

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.
