History

The company was founded in 1991 by Richard Barclay, Michael Beley, Gary D. Nordin, Marco Romero and Chester Millar. In July 2008, we took over Frontier Pacific Mining and their gold deposit in the Greek Perama, in December of the same year sold to a mine in Brazil's São Bento at AngloGold Ashanti. 2009, the subsidiary Minera Frontera Pacifica was sold to the Solex Resources. Minera Frontera Pacifica explored a uranium deposit on the Macusani Plateau in Peru. In December 2011 they bought for 2.5 billion Canadian dollars European Goldfields Limited, which included a mine and deposits in Greece, Romania and Turkey. The gold mines of Eldorado in Greece have been repeatedly blocked by local residents, was created in early 2013 in an attack damage in the millions. The Greek government denounced this and wants to give more Eldorado Gold mining permits, Greece is to be according to the company from 2015, the largest gold producer in Europe. The projects are criticized because of their location in the dense forest areas of Northern Greece, is also a strong impact on the environment is concerned.

Locations

Eldorado Gold has several mines and deposits are explored.

Mining areas

Kisladag

The mine Kisladag is the largest gold mine in Turkey, located in the province of Usak, approximately 180 kilometers east of Izmir at an altitude of around 1000 meters. Kisladag is located in a relatively young Tertiary volcanic complex, which was built on the basis of the subduction of the Hellenic trench. The bulk of the gold is found in porphyry, which is located in latitischem intrusive. The ore body forms a ring around a weakly mineralized zone, the gold is often found together with tourmaline, pyrite, quartz - pyrite veins and breccias and small amounts of metals such as zinc and molybdenum. The commercial mining began in the third quarter of 2006, since the output of the mine has increased annually. 2012 were produced 289 294 ounces of gold with production costs of 312 U.S. dollars per ounce.

Efemçukuru

The mine is located near Efemçukuru Kisladag, but the gold is mined underground. The rock consists of epithermal, low sulfide -containing vein structures. The gold is found in steeply dipping quartz and Rhodonitadern, the surrounding rock consists of hornfels and phyllite. It identified three very gold-bearing zones that are open one to 27 meters wide and down. About 1100 tons of rock are promoted per day, which are then crushed. After flotation, the gold -containing liquid is taken for further processing after Kisladag. Near the mine wine terraces were created for local farmers. The mine took in December 2011 on commercial production in 2012 produced a total of 66 870 ounces of gold at production cost of 583 U.S. dollars per ounce.

Jinfeng

The Jinfeng mine is located in China's Guizhou Province, about 240 kilometers southwest of Guiyang. The landscape consists of karst hills, the climate is subtropical and relatively moist. The mine is located in Triassic clastic sedimentary rocks, above limestone from the Permian and Carboniferous. The gold is in an approximately 1300 meter long wire that runs from the surface in an east - southeasterly direction to a depth of about 1000 meters. There is another, very ore-grade, vein that runs horizontally. The gold is mined in open pit and underground. The construction of the infrastructure began in 2005, in September 2007, the commercial gold production began by Sino Gold. In December 2009, Eldorado Gold bought gold for two billion dollars Sino. The produced amount of gold was in 2012 at 107 854 troy ounces, the production costs of 817 U.S. dollars per ounce.

Tanjianshan

The mine Tanjianshan located in the province of Da Qaidam, about 260 kilometers north of Golmud in the northwest of the People 's Republic of China. The mine is located in the Saishiteng Mountains at an altitude of around 3300 meters, the landscape consists of steep mountain slopes that are no growth because of the dry climate. The gold is mined in open pit and underground. The first degraded Qinlongtan deposit consists of a gold vein which runs to the east at an angle of 50 ° to 60 ° back and cuts through phyllite and marble. The vein is about 5 to 10 meters wide. The degraded since 2012 Jinlonggou deposit is on the surface of carbonaceous phyllite, in the depths of diorite porphyry sills. The commercial gold production in Tanjianshan was recorded in early 2007, Eldorado Gold was the first North American mining company that operated a mine in the People's Republic of China. 2012 were produced 110 611 ounces of gold at production costs of U.S. $ 415 per ounce.

White Mountain

In the Chinese province of Jilin, about 230 kilometers southeast of Changchun and 7 kilometers north of Baisha, the mine is White Mountain. The gold is in silicified breccia, which is traversed by veins of pyrite and is located in proterozoischem sedimentary rocks. Accessory minerals are pyrite in addition to silica, iron oxide and barite. The mine was built in 2008 and in January 2009 began commercial gold production. In August 2009, the attack was stopped because local farmers accused the operator of the mine water pollution. In January 2010, the attack was resumed. 2012 produced 80 869 ounces of gold at production costs of U.S. $ 625 per ounce.

Vila Nova

The mine Vila Nova located in the northeastern Brazilian state of Amapá, about 175 kilometers west of Macapa. This iron ore is mined with an iron concentration of 63.9 percent. The construction of the mine began in 2009, in the third quarter of 2010 began trial operation. 2011 began with the commercial mining, in 2012 there were 584 356 tonnes of ore at a cost of 60.50 U.S. dollars per ton.

Stratoni

The mine is located in Stratoni on the Greek peninsula Chalkidiki, about 100 kilometers southeast of Thessaloniki. 3.5 km from the village Stratoni lies with loading facilities at the port. The area is forested with oak, beech and pine trees. Due to the mild temperatures by about 20 degrees Celsius, the operation can be maintained all year round upright. The ore is located in sulfide- rich carbonate and aplite, in two marble horizons with Biotitgneis and shale between. In Stratoni lead, zinc and silver are mined, the accessory minerals are pyrite, galena, sphalerite, arsenopyrite and chalcopyrite. Small amounts of gold are found together with arsenopyrite. The currently mined ore body is approximately 500 meters long, 25 meters wide and 100-340 meters thick. The gold content is four to six grams per ton of rock, but has no economic value. The reserves of the area were measured in 2010 to 1.8 million tonnes at 10.8 percent zinc, 7.8 percent lead and 217 grams of silver per ton, which are a total of 200,000 tonnes of zinc, 140,000 tons of lead and 12.7 million troy ounces of silver. The concession for the mining area was sold by the Greek government to Eldorado Gold 2004. 2012 produced 50 680 tonnes of one lead-zinc concentrate for 905 U.S. dollars per ton, with production costs of 729 U.S. dollars per ton.

Deposits

Eastern Dragon

The Eastern Dragon project is located in the north of China's Heilongjiang Province, about 45 kilometers southeast of Xunke. The winters are hard, explorations can be carried out from April to October. The gold and silver is in several veins that are surrounded by volcanic rock and granite rocks. The ore grade is 16 grams of gold and 128 grams silver per ton of rock. The reduction is initially done in the open pit and the underground to reach the deeper veins later. In 2012, the tests began, from 2014, the mine produced 80,000 ounces of gold annually.

Tocantinzinho

The reservoir Tocantinzinho is located in the Brazilian state of Pará, in the north of the country. The area was purchased in 2010 and researched since 2012 were drilling carried out by the geochemical and geophysical events to explore around the proposed mine. A feasibility study should be completed in early 2014 and when the permission for the construction of the mine shall be issued in 2016 start commercial gold production. The deposit contains measured reserves of 1.975 million tonnes at a grade of 1.25 grams per tonne, the annual output is to be around 160,000 ounces of gold.

Perama Hill

The Perama Hill is located in the eastern part of the Thrace region, about 30 kilometers northwest of Alexandroupolis. The deposit is located about five kilometers from the sea in a hilly karst landscape. The rock consists of rocky sandstone underneath this, andesitic breccias and volcanic. The ore body has a north- south length of approximately 750 meters and up to 300 meters and an east-west direction. The thickness is 15 to 20 meters on the sides of the hill and up to 120 meters at the top. The very fine-grained gold is evenly distributed in the sandstone. The reduction shall be in an open pit, with an output of 1.2 million tonnes a year. The mine is supposed to be eight years in operation. The area in 2012 was investigated by the distribution of gold in the ground to better determine the commercial production of 110,000 ounces of gold per year, to begin in 2015.

Olympias

The Olympias project is located near the mine in Stratoni. The deposit is located in the Kerdilia formation, the rock is composed of gneiss and marble. Occurring minerals are pyrite, arsenopyrite, sphalerite, galena, tennantite, and chalcopyrite with secondary Boulangerite Cerussite, chalcocite and covellite. Occurring gangue consists of quartz, calcite, rhodochrosite, feldspar, kaolin, chlorite, ankerite and graphite. The ore is located in two zones, the western is about 1500 meters long, 250 meters wide and five to 15 meters thick. The eastern zone is located about 150 meters east of the western zone, it is an average of 75 meters wide and seven meters thick, the length has not yet been determined. The ore is mainly in two zones in south-north direction and falls to southeast at an angle of 25 ° to 35 °. The mine is a year to produce approximately 300,000 to 400,000 tons of rock. The measured reserves of the deposit containing 4.1 million ounces of gold, 58.8 million troy ounces of silver, 599,000 tonnes of lead and 796,000 tonnes of zinc. 2012 they produced in test mode 826 troy ounces of gold.

Skouries

The Skouries project is located southwest of Stratoni, in the same concession area. The deposit is a sub - alkaline copper porphyry deposit, which is located in an almost horizontal position and is surrounded by amphibolite and biotite schist. Mainly occurring minerals in potassic zone are Chalkopyritäderchen with small amounts of bornite. The gold is found in pure form along with gangue and as small bubbles in sulphides. There are two very ore-bearing zones, one near the surface and the other at a depth of around 350 meters. First the ore is to be promoted in an open pit, the deeper ore body is to be developed by underground mining. It is copper-gold concentrate will be produced, which is then to be shipped from the port in Stratoni or Thessaloniki. The measured reserves of the deposit are 3.6 million ounces of gold and 736,000 tonnes of copper.

Certej

The Certej project is located in Romania, near the city of Deva. The deposit is located in the southern part of the Apuseni Mountains, where in earlier times was held gold mining. The sediments containing gold are from the Cretaceous and Miocene, but there are Neogene andesite. The ore is found in a 1.5 -kilometer zone that extends in an east-west direction. The measured reserves of the deposit amount to 2.41 million ounces of gold and 17.3 million troy ounces of silver. The construction of the infrastructure of the mine should begin in 2013, the mine shall be for twelve years in operation.
