The Tanjianshan Mine is located in Qinghai Province in Western China. The property covers 338 km2 comprising of four exploration licenses and two mining licenses. The mine consists of two separate deposits - Qinlongtan ("QLT") and Jinlonggou ("JLG"). The mine and mill were commissioned in late 2006 and commercial production was declared in February, 2007. 2007 total production was 138,162 ounces of gold at a cash operating cost of US$288/oz. Production in 2008 is forecast at 109,000 ounces of gold at a cash operating cost of US$289/oz.

The Tanjianshan Mine is a significant achievement for Eldorado Gold. We are the first North American gold producer in China, and intend to use this advantage to continue building our business in China.

Geology

At QLT, gold mineralization is confined to 50 - 60° east dipping shear zone which cuts across a sequence of phyllites and marbles. The shear zone is typically 5 to 10 meters wide, and is open at depth.

At JLG, surface mineralization is dominantly controlled by steeply dipping, north-east trending shear zones within carbonaceous phyllites. At depth and in the eastern part of the deposit, mineralization is associated with sub-horizontal diorite porphyry sills.

At QLT, the gold occurs mainly as fine grained free gold and associated with pyrite and is non-refractory. At JLG, gold is associated with pyrite and to a lesser extend arsenopyrite and is mainly refractory.

Mining and Processing

QLT and JLG is mined by conventional open pit methods using a combination of owner operated and contract equipment. The licensed production rate is 800,000 tonnes per annum. The mine life is approximately 10 years.

The metallurgical plant will be set up to handle both refractory and non-refractory ore. Non-refractory ore will be subjected to whole ore CIL, while refractory ore goes through a floatation circuit followed by roasting of the floatation concentrate.
