First pour, recorded January 31, was made on schedule and ahead of budget. Officials said the "initial conviction and perseverance" of its exploration team milestone, as Öksüt first began as a greenfield exploration venture in 2009.
The Öksüt operation, which Centerra owns wholly, is the company's third operating mine and source of gold production.
According to president and CEO Scott Perry, Öksüt also met a second milestone during the week: two million work hours lost-time injury free.
"Reaching the first gold pour is a testament to the dedication and hard work that our Öksüt team has put in to reach this goal safely," he added.
Perry told MM sister publication Mining Journal last September that Öksüt would be its "distinguishing" asset, adding 110,000 ounces per year to its production profile over eight years.
Mid-tier Centerra Gold's two other flagship assets include the Kumtor mine in Kyrgyzstan and the Mount Milligan mine in British Columbia, Canada.
