Kinross Gold CorporationMaricunga Mine Technical Report23.0 ADDITIONAL REQUIREMENTS FOR OPERATINGPROPERTIES23.1 Mining OperationsThe Maricunga Mine is an operating mine with significant infrastructure in place. The reserveestimates presented in this document are sufficient to support the operation for 16 yearsbased on daily production of 45,000 tpd.Maricunga production re-opened in October 2005 and achieved its targeted production rateof 14 million tonnes per year (40,000 tonnes per day) in late 2005. The mine operates two12-hour shifts per day for 352 days annually allowing for inclement weather interruptions.Final pit design for Verde and Pancho assumed 10 meter bench heights, bench face anglesof 65° to 70°, berm widths of 8 to 11 meters, berm interval of 20 meters, inter-ramp angles of38° to 52.5° and haul road gradient at 10% with a 25 meter road width.The Maricunga gold recovery process consists of a single line primary crushing, finescrushing (secondary and tertiary), heap leach and adsorption and regeneration (“ADR”) plantoperation. The process treats 45,000 tonnes per day of dry Maricunga ore using primarycrushing followed by a secondary and tertiary crushing plant. The crushing plant product isapproximately 80% passing 10.5 millimetres. A pad type heap leach and an ADR plant areused for gold recovery.A comprehensive program of metallurgical testing incorporating bottle roll tests and columnleach tests of samples obtained from drilling was established to determine gold recovery andreagent consumption data for the remaining Verde resources and the Pancho resource.Based on the recovery estimates by ore type, process recovery over the mine life averaged69% of contained gold in the plant feed. Life of mine annual gold production is expected torange from 230,000 to 305,000 ounces on a 100% basis.The increase in reserve as of December 31, 2007 will require an expansion of the heapleach facility. This report considered the findings of a pre-feasibility study level completed byDave Prins of PrinZ Mining Services based in Santiago, Chile. The increased reserves will105
