Technical Report for the Maricunga Gold Mine - Kinross Gold

Kinross Gold CorporationMaricunga Mine Technical Report16.0 MINERAL PROCESSING AND METALLURGICAL TESTINGThe 2002-2003 Exploration Program included the following metallurgical and physicalproperty test work for both Verde and Pancho:• cyanide soluble gold analyses• cyanide soluble copper analyses• direct agitated cyanidation tests (bottle roll)• column leach tests• Bond work index tests• specific gravity determinations• Acid Based Accounting (ABA) testsThe 2006 drill program on Pancho also provided representative material to performadditional metallurgical testing. Cyanide soluble gold and copper analyses weresystematically completed for all samples. Recent test work included bottle roll and 14column leach tests. The results based on the 2006 data collection are summarizedseparately in this section.Finally, during 2007 the SART process was considered for the Pancho ore as uneconomicconcentrations of copper are present in ore. Some of the copper minerals are soluble incyanide solutions and these minerals consume cyanide reagent and contaminate the leachsolution with copper metal. A feasibility study and pilot testing program were completed in2007. The study considers plant design, performance metrics, operating and capital costsand implementation strategy. The reserves defined at Pancho consider the application of theSART process.59
