Eldorado Gold increased the gold production from 64,298 ounces in 2005 to 632,539 ounces in 2010, despite the closure of the São Bento in 2007, by bringing Kişladağ into production in 2006, acquiring the Toronto Stock Exchange-listed Afcan Mining Corporation for its Tanjianshan Mine which it had 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.
