Eldorado Gold Provides Lamaque Exploration and Development Update

TSX: ELD   NYSE: EGO

VANCOUVER, June 20, 2018 /PRNewswire/ - Eldorado Gold Corporation ("Eldorado" or the "Company") is pleased to provide an update on its exploration programs and construction progress at the Lamaque project in Quebec. Mill refurbishment and underground mine development are ahead of schedule and production from the refurbished mill remains on track for 2019.  Exploration results include over 12,000 metres of resource expansion drilling received since the 2017 year-end resource update.

Exploration Highlights 

Drilling subsequent to year-end focused on the lower part of the Triangle deposit as well as targets along strike and down dip from the Parallel deposit.  Highlights include:

• Delineation of new mineralized zones C8, C9, and C10 at Triangle, with intercepts as high as 2.8 metres at 125.45 g/t Au (C6 secondary splay) and 1.8 metres at 873.96 g/t Au (C8 secondary splay).  These new zones are not included in the 2017 resource estimate.
• Intercepts of 3.4 metres at 7.47 g/t Au and 4.3 metres at 7.68 g/t Au at C7 at Triangle, representing stepouts of 100 metres and 150 metres, respectively, from nearest previous intercepts.
• A stepout intercept of 3.5 metres at 27.62 g/t Au at the Parallel deposit, 125 metres downdip from nearest previous intercepts.  Stepout drilling has linked the mineralized shear zones with historically mined zones at nearby Lamaque and Plug 5 deposits.

"Results from this year's exploration drilling continue to demonstrate the outstanding resource upside potential of the Lamaque project," said
Peter Lewis, Eldorado's Vice President, Exploration.

"Our new drilling at Triangle confirms that the shear-hosted vein systems and steeply plunging intrusions that control mineralization in the upper deposit persist to at least 1,800 metres depth, with high grades reported in several newly-identified shear zones and in related secondary shear zones and extension vein systems.  At the Parallel deposit, step-out drilling has linked the mineralized shear zones with historically mined zones at the nearby Lamaque and Plug 5 deposits.

"We have approximately 10,000 additional metres of drilling planned for this year focused on resource expansion in the lower Triangle deposit, and further testing and definition of new targets.  An additional 10,000-12,000 metres of underground resource conversion drilling will target the 686,000 inferred ounces defined in the C4 and C5 zones.  Drilling access will also be available from the newly constructed and dedicated drilling platforms on the 166 and 184 levels of the Triangle underground." (See Figure 1).

Development Highlights

The Lamaque project remains on schedule to enter commercial production in early 2019. There are currently over 250 workers on site with headcount expected to grow by 20% over the next six months.  Progress to-date underground includes:

• Approximately 8,500 metres of total development, which is ahead of plan
• Development rates averaging over 20 metres per day
• Main ramp now at a depth of ~240 metres below surface
• Ore processed through a nearby toll mill, with recovery and reconciliation consistent with our internal life of mine model

Refurbishment work on the Sigma Mill continues to ramp up, including:  

• Replacement and refurbishment of the CIP tanks
• Refurbishment of the main mill motors
• Procurement of new electrical switchgear
• Installation of the process control system has commenced in anticipation of a staged start up

The projected 2,200 tonnes per day capacity of the refurbished Sigma process plant provides excess milling capacity over what is required for the initial production from the Triangle deposit. The focus is to increase mill production from other sources within and nearby the project area. Mill capacity can be further increased (up to 5,000 tonnes per day) through the installation of an additional grinding mill. 

Recent Exploration Results

Lower Triangle Deposit

The 2017 resource for the Triangle deposit included 1.06 million ounces of gold in the Measured and Indicated categories in the C1, C2, and upper part of the C4 mineralized zones, and 1.11 million ounces of gold in the Inferred category mainly in the lower C4, C5, and C7 mineralized zones, based on a 2.5 g/t Au cutoff grade.  Drilling completed since the 2017 resource estimate has targeted the lower Triangle Deposit below the C4 zone. 

The drilling has defined new mineralized shear zones referred to as C8, C9, and C10, as well as secondary shears related to these zones and to the structurally higher C6 and C7 zones.  To date, C7 and C10 are the most strongly developed zones in terms of deformation intensity and displacement magnitude, and display the best continuity of mineralization.  Zones C6, C8 and C9, as well as secondary shear zones associated with them, also contain high gold grades, with best intercepts concentrated peripheral to intersections of the shear zones with dyke contacts (Figure 2). 

C7 Zone

Current Inferred Resources for the C7 Zone total 116,000 ounces at an average grade of 6.7 g/t, based on drillholes that tested an area measuring approximately 400 metres by 400 metres.  Recent stepout drilling included intercepts of:

• TM-18-321A: 3.4 metres at 7.47 g/t Au at a distance of over 150 metres outside of the Inferred Resource
• TM-15-038W02: 4.3 metres at 7.68 g/t Au

The limited drilling completed to date on C7 suggests that best grades and thicknesses are aligned in two nearly orthogonal shoot orientations, similar to the pattern of grade distribution in the upper zones of the Triangle deposit.  These shoots are open in multiple directions, defining priority targets to further expand resources.

C10 Zone

The newly-defined C10 zone forms a shear zone system consisting of multiple anastomosing splays within a broader deformation zone up to 30 metres  wide.  It dips approximately 65°- 75° to the south, slightly steeper than the upper shear zones of the Triangle Deposit.  High gold grades have been identified within the C10 zone over an area measuring approximately 400 metres along strike by 200 metres vertically, and define a mineralized trend that remains open downdip and along strike to the east (Figure 3 and Appendix 1).  Significant gold intercepts within C10 include:

• TM-15-032W04: 2.7 metres at 16.17 g/t Au
• TM-18-321AW01M01: 5.5 metres at 8.16 g/t Au
• TM-15-008W01M01: 8.1 metres at 7.70 g/t Au
• TM-15-032W03: 6.1 metres at 3.60 g/t Au
• TM-15-006: 4.8 metres at 8.05 g/t Au

Other Lower Zones at Triangle

New high-grade drillhole intercepts from the C6, C8, and C9 zones and their associated secondary splays are mainly localized within an area near where these shear zones cut a southern branch of the Triangle intrusive system (Figure 2).  Together, these define a steeply-dipping zone prospective for high-grade mineralization that is similar to overall controls in the upper Triangle deposit.  Examples of significant intercepts from this zone include:

• TM-15-032-W03: 9.30 metres at 8.99 g/t Au (C6)
• TM-15-038-W02: 2.8 metres at 125.45 g/t Au (C6 secondary splay)
• TM-15-032-W03: 18.2 metres at 8.05 g/t Au (C8)
• TM-15-006-W01M01: 4.5 meters at 29.28 g/t Au (C8 secondary splay)
• TM-15-032-W04: 1.8 metres at 873.96 g/t Au (C8 secondary splay)

Parallel - Plug 5 Corridor

The Parallel Deposit contains Indicated Resources of 70,000 ounces at a grade of 9.92 g/t Au and additional Inferred Resources of 57,000 ounces at a grade of 8.7 g/t Au.  Approximately 80% of these resources occur within a series of four stacked south-dipping shear veins, which together define a tabular mineralized zone with a strike length of at least 300 metres and a dip extent of 250 metres.  These shear zones project westward along strike and are correlated with historically mined veins at the Lamaque mine.  The 400 metre gap between these deposits has only been sparsely drill-tested.  To the east, the same shear vein system correlates with mineralized shear zones in the upper part of the Plug 5 deposit.  Together, these systems define a south-dipping mineralized corridor that extends over at least two kilometres strike length but remains open and mostly untested to the east (Figure 4).

New drilling along this mineralized trend includes 11 drillholes targeting potential down-dip extensions to the Parallel Deposit, and untested areas to the south of the Plug 5 deposit.  Notable results include:

• Intersections of 0.7 metres at 38.39 g/t Au and 0.8 metres at 86.5 g/t Au in drillhole PV-18-27, from the down-dip continuation of the uppermost shear vein at the Parallel deposit.  This intersection is a 125 metre stepout from the nearest drillhole, and highlights the potential for additional high grade resources at the Parallel deposit.
• An intersection of 4.3 metres at 5.25 g/t Au in drillhole PV-18-029, located to the south of Plug 5 and 200 metres along strike to the east of the Parallel deposit.  This intersection is hosted by a shear zone that was mined historically updip in the Plug 5 deposit, and also correlates with a lower shear zone defined at the Parallel deposit.

Cautionary Note to US Investors Concerning Estimates of Measured, Indicated and Inferred Resources
The terms "mineral resource", "measured mineral resource", "indicated mineral resource", "inferred mineral resource" used herein are Canadian mining terms used in accordance with NI 43-101 under the guidelines set out in the Canadian Institute of Mining and Metallurgy and Petroleum (the "CIM") Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as may be amended from time to time. These definitions differ from the definitions in the United States Securities & Exchange Commission ("SEC") Industry Guide 7. In the United States, a mineral reserve is defined as a part of a mineral deposit which could be economically and legally extracted or produced at the time the mineral reserve determination is made.

While the terms "mineral resource", "measured mineral resource," "indicated mineral resource", and "inferred mineral resource" are recognized and required by Canadian regulations, they are not defined terms under standards in the United States and normally are not permitted to be used in reports and registration statements filed with the SEC. As such, information contained herein concerning descriptions of mineralization and resources under Canadian standards may not be comparable to similar information made public by U.S. companies in SEC filings.

Accordingly, information herein containing descriptions of our mineral deposits may not be comparable to similar information made public by US companies subject to the reporting and disclosure requirements under US federal securities laws and the rules and regulations thereunder.
