Africa's third biggest miner of the precious metal behind South Africa and Ghana produced about 43.5 tonnes of gold ore, versus just over 46 tonnes in 2010, he said over state television.
"The outlook for 2012 is even better, with strong prices for gold but mostly because of the start-up of new mines," Toure said, without giving any forecasts.
The price of gold rose 10 percent in 2011, its 11th consecutive year of gains, as investors sought refuge from tumbling equities and bonds markets.
Toure has been in power in the West African state since 2002 and has said he does not plan to stand in elections set for later this year.
He said the two mines that would begin production this year were Randgold's Gounkoto mine and Wassoul'Or's Kodieran mine, part owned by German-listed Pearl Gold.
