Canada-based gold producer Eldorado Gold Corp. said Tuesday it has agreed to acquire 57.9 million shares of Sino Gold Mining Ltd., an Australian company, in exchange for 27.8 million of its shares.

The amended agreement provides for filing a prospectus for the Gold Fields Transaction and extends the closing date before the end of July, subject to certain conditions.

Sino Gold focuses on exploring and mining gold in China with two operating mines.

Shares of Eldorado, based in Vancouver, British Columbia, rose 26 cents, or 3 percent, to $8.73 in afternoon trading.
