Eldorado Gold Announces Maiden Inferred Mineral Resource of 803,000 Ounces at 9.5 g/t Gold at the Ormaque Deposit in Quebec

VANCOUVER, British Columbia, Feb. 22, 2021 (GLOBE NEWSWIRE) — Eldorado Gold Corporation, (“Eldorado” or the “Company”) is pleased to announce a maiden resource estimate for the recently-discovered Ormaque deposit near its Lamaque operations (Figure 1) in Quebec. Inferred Mineral Resources total 2,620,000 tonnes at a grade of 9.53 grams per tonne gold, for 803,000 ounces of contained gold.
“This early exploration success at Ormaque highlights the outstanding growth potential at Lamaque,” said George Burns, President and CEO. “The short time frame from initial discovery to maiden inferred resource is a testament to the drive of our team and the strong exploration potential within our land package in the Abitibi Greenstone Belt. The strike continuity, vein orientation and dimensions of the Ormaque deposit exhibit important similarities to parts of the nearby historically mined Sigma deposit and Mine #2. It is ideally positioned along the ore haulage decline now under construction connecting the Lamaque-Triangle Mine with the Sigma Mill. Our focus in 2021 is on in-fill and expansion drilling as the deposit remains open in multiple directions. We are encouraged by these positive results and look forward to further work to determine the ultimate scale of this exciting early stage project.“Taken together with our recently-announced friendly transaction to acquire QMX, Eldorado is well-positioned in Quebec to create additional value for our stakeholders.”Ormaque Deposit Geology and Inferred Mineral ResourceThe Ormaque deposit is located approximately midway between the Lamaque-Triangle Mine and the Sigma Processing Facility. It is immediately adjacent to the ore haulage decline currently under construction linking the two, with the upper part of the deposit at the same elevation as the decline (Figure 2). At current development rates the decline will reach a position adjacent to the Ormaque deposit in Q3 of 2021.High grade gold at Ormaque occurs within subhorizontal to gently south-dipping lenses consisting of quartz+carbonate+tourmaline extension veins and vein arrays and tourmaline-altered wallrock, similar in style to those historically mined in parts of the nearby Sigma Deposit (historical production of 4.5M ounces gold) and Mine #2 Deposit (over 237,000 ounces gold produced between 1950 and 1955). The extension veins are concentrated along an east-west corridor defined by a series of steeply north-dipping brittle-ductile shear zones. Nearly all of the deposit outlined to date occurs within an irregular diorite intrusion known locally as the “C-Porphyry”, which is also the dominant host rock at Sigma and Mine #2.Inferred Mineral Resources are based on results of 37 diamond drillholes totalling 22,602 meters, most of which were completed since May 2018. This drilling has outlined a volume of mineralization measuring approximately 550 metres east-west, 300 metres north-south, and extending from 150 to 600 metres depth from surface. The geological model of the mineralized lenses was generated by 1) converting individual assays to composites of drill core intervals averaging > 0.5 g/t Au and a minimum length of 0.5m; 2) creating form interpolants using vein orientations of the dominant mineralized vein sets measured from oriented drill core; and 3) employing the form interpolants to correlate composites between drillholes. This process generated 23 gently-dipping mineralized lenses, with individual lenses measuring up to 15 metres thick and up to 400 metres in lateral extent (Figure 3). Individual lenses were then trimmed to exclude volumes more than 50 metres from drillhole intercepts.A grade estimation block model was generated using ordinary kriging of drillhole assays composited into 1m lengths and capped at 70 g/t Au to limit the influence of high-grade outliers. A 3.5 g/t cut-off grade was applied to incorporate areas of mineralization with reasonable prospects of eventual economic extraction. The cut-off grade was derived from actual cost and metallurgical performance of the Triangle deposit and includes the following forward-looking assumptions:Gold price = $US 1800/oz$CAD / $US exchange rate = 1.3Minimum mining height = 3 metresMining recovery = 95%Mining dilution = 20% with no contained gold valueMetallurgical recovery = 96%Mineralized domains were edited to excluded volumes that did not meet or exceed a diluted cut-off grade of 3.5 g/t Au over the minimum mining height of 3 metres. Isolated cells above cut-off were also discarded.The resulting inferred resource totals 2,620,000 tonnes at a grade of 9.53 g/t Au, for 803,000 contained ounces of gold. Over 60% of the resource is in the upper part of the deposit within 400 metres of surface.Exploration OutlookMost of the mineralized lenses are open laterally in one or more directions, and the deposit itself is open to the east, west, and at depth. Drilling for the first half of 2021 will include infill holes within several of the upper lenses to confirm continuity of grade and thickness of the inferred resource, step-out holes targeting open extensions to these lenses, and wider step-out holes testing for longer extensions and new lenses in areas adjacent to the deposit. Some of the more prospective targets for the latter include 1) the untested area below the Fortune Zone immediately east of Ormaque, where shallow drillholes have intersected similar vein styles to those found at Ormaque, and 2) gaps in previous drilling between the Ormaque deposit and the Parallel deposit to the west (Figure 4).Lamaque Operations Background and Regional StrategyThe Lamaque Operations is home to a number of large prolific gold mines, including the historic Sigma and Lamaque mines that together produced almost 10 million ounces of gold. Today, it hosts Proven and Probable gold reserves of over 1 million ounces, Measured and Indicated Mineral Resources of 1.8 million ounces of gold, and Inferred Mineral Resources of 2.8 million ounces of gold at the Triangle, Plug #4, Parallel, and Ormaque deposits.Our strategy in the region is designed to add a pipeline of organic opportunities within and proximal to the Lamaque-Triangle Mine, which can be exploited by leveraging existing infrastructure and Eldorado’s strong operational, exploration and stakeholder expertise. We aim to achieve this by increasing our footprint in the Abitibi Greenstone Belt and through providing additional ore sources to optimize the Sigma Mill, which has a permitted capacity of 5,000 tonnes per day, far exceeding current usage of 2,200 tonnes per day.Figure 1: Location map showing Lamaque Operations.
