MAURITANIA – Kinross Gold Corp. of Toronto has a pre-feasibility study in hand for its Tasiast gold project, and the company is going forward with a full feasibility study for a 38,000 t/d mill at the project. A new mill will replace the 8,000-t/d facility now in use.

The PFS looked at the economics of a 30,000-t/d mill, using the existing 8,000-t/d mill as well as the 30,000-t/d plant, and building a single, new 38,000-t/d facility. The third option was the most attractive, and Kinross will begin work on the feasibility study immediately with completion expected in Q1 2014. The construction of a standard carbon-in-leach (CIL) circuit with a primary crusher and SAG mill will be assessed in addition to the existing dump leach facilities. A series of pushbacks that would allow the open pit to reach expected higher grade ore early in the mine life. A variable cut-off grade strategy is expected to be applied to bring gold production forward and stockpile lower grade material for processing later in the mine life. The use of natural gas rather than heavy fuel oil for power generation will also be studied.

Kinross became owner of the Tasiast mine in September 2012 when it acquired Red Back Mining. Visit Kinross.com for detailed information about the mine.
