<strong>Kinross</strong> <strong>Gold</strong> Corporation<strong>Maricunga</strong> <strong>Mine</strong> <strong>Technical</strong> <strong>Report</strong>A 35,000 meter drill program was approved in September 2002 with <strong>the</strong> objective of adding20 million tonnes of Measured and Indicated resource at both Pancho and Verde. Thismineralization had to be recoverable through open pit mining methods. Follow-up work tofur<strong>the</strong>r delineate <strong>the</strong> mineralization, provide representative metallurgical samples anddetailed geotechnical in<strong>for</strong>mation would be contingent on <strong>the</strong> initial results of <strong>the</strong> drilling.The in<strong>for</strong>mation was collated and incorporated in new mineral resource and mineral reserveestimates <strong>for</strong> Verde and Pancho. The reserves were based on a detailed engineering studyexamining <strong>the</strong> economics of <strong>the</strong> project assuming a capital investment of $101.1 million toupgrade <strong>the</strong> existing infrastructure, allowing <strong>the</strong> plant to process 40,000 tonnes per day ofVerde ore and 35,000 tonnes per day of Pancho ore. The capital investment was based onpreliminary design and first-principle engineering. Capital cost estimates were prepared andverified by two, independent, North American engineering consultants with significantexperience in Latin America.The <strong>Maricunga</strong> <strong>Mine</strong> resumed full production in October 2005 at a rate of 40,000 tpd. Totalproduction of 233,000 ounces from 14,333,000 tonnes at 0.74 g/t Au is reported <strong>for</strong> 2007.Table 6-1 summarizes <strong>the</strong> production history of <strong>Maricunga</strong>.Table 6-1: Annual <strong>Gold</strong> Production of <strong>the</strong> <strong>Maricunga</strong> <strong>Mine</strong><strong>Mine</strong>d Grade <strong>Gold</strong>Year tonnes <strong>Mine</strong>d Production(x 1,000) (Au g/t) (ounces)1996 7,617 1.03 101,2761997 7,789 1.02 147,0851998 8,207 0.93 161,0461999 8,936 0.94 179,4652000 8,801 0.94 169,8322001 4,643 0.95 133,9472002 - - 26,0942003 - - 5,0002005 6,214 0.87 121,6702006 14,872 0.74 233,8362007 14,333 0.74 233,000TOTAL 81,412 0.88 1,512,25130
