acquired two years previous from Sino Gold Mining, and then acquiring Australian Securities Exchange-listed Sino Gold Mining, in a 2009 $1.6 billion all-stock deal, for their new Jinfeg and White Mountain mines. During this period of growth, Eldorado and Centerra Gold considered merging their operations but were unable to find sufficient advantages. Eldorado went on to be added to the S&P/TSX 60 in 2009 as one of the largest companies listed on the Toronto Stock Exchange. In 2010 Eldorado acquired, in an all-stock deal worth $122 million, TSX Venture Exchange-listed Brazauro Resources for their share of the Brazilian Tocantinzinho exploration project. Later that year, Eldorado offered a $3.4-billion all-stock deal to acquire ASX-listed Andean Resources for their Cerro Negro project but were out-bid by Goldcorp who offered $3.6-billion in cash and stocks. Instead, Eldorado went on to acquire TSX-listed European Goldfields for $2.5-billion in stocks for its projects in Greece, as well as exploration properties in Romania. Eldorado's gold production peaked at 789,224 ounces in 2014 from its three mines in China, the Kişladağ mine in Turkey, supplemented by its second Turkish mine (Efemcukuru) which came online in 2012 and the old Olympias mine in Greece which the company was able to begin retreatment of leftover tailings. Eldorado Gold began a years long decline as it committed to selling its mines in China in favour of developing its properties in Greece. At the time, during its economic crisis, Greece was actively seeking foreign investment and its Skouries project had the potential to be a high producing, long-lived (over 20 years) gold and copper mine. Other companies had previously attempted to develop the Skouries mine but the government had deemed it as not being in the national interest but the need for foreign investment reversed that decision. However, Eldorado's projects in the Chalkidiki region had long been controversial as other mining projects left locals with little confidence in the government's ability to effectively regulate mining and manage economic development. The company spent US$1 billion by 2017, mostly on the Skouries project, without completing a mine and experiencing protests against the project, due to land clearing in a popular forest and anticipated impacts to environmental values, tourism and agriculture, as well as protests in favour citing the number of jobs the mining project represented. Eldorado Gold's assets in China were sold to China National Gold Group Corporation and the Shenzhen-listed Yintai Resources
