Kinross Gold CorporationMaricunga Mine Technical Report1.0 SUMMARYThis Technical Report for the Maricunga Mine has been prepared to support the 2007Kinross Gold Corporation (Kinross) Annual Mineral Resources and Reserves Statement andhas been prepared under the direct supervision of the qualified person, Maryse Bélanger, P.Geo., Director Technical Services, Kinross Americas with contributions from CMM technicalstaff.The Maricunga Gold Mine is located in the Maricunga Gold Belt in Region III of northernChile. The property is located 120 km due east of the city of Copiapó at elevations between4,200 and 4,500 meters above mean sea level. The mine operated from 1996 to 2001,producing more than 920,000 ounces of gold from 46.0 million tonnes of ore. The mine wasplaced on care and maintenance in 2001, due to a downturn in gold prices. The MaricungaMine complex comprises two open-pits, Verde East and Verde West and a neardevelopmentproject called Pancho.The Maricunga heap leach mine is owned and operated by Compañía Minera Maricunga(CMM), a Chilean company that is wholly-owned by Kinross since its acquisition of BemaGold Corporation effective at the end of February 2007.The Verde and Pancho gold deposits at Maricunga occur in the Maricunga Gold Belt of thehigh Andes in northern Chile. Since 1980, a total of 40 million ounces of gold have beendefined in the belt, (Muntean and Einaudi, 2000). Gold mineralization at Maricunga hasbeen interpreted as porphyry style gold systems and is hosted in the Maricunga volcanicintrusivecomplex of Early Miocene age. The porphyries occur within a sequence ofintermediate tuffs, porphyries and breccias that are the host rocks to the gold mineralization.Gold mineralization at Verde is interpreted to be the result of the fracturing and concentrationof fluids in the carapace of an intrusive plug or stock. Gold is closely associated with quartz,magnetite, calcite, and garnet stockworks. Gold mineralization at Pancho is characterized asporphyry hosted stockwork and sheeted veins. The veins are subvertical and have a strong,preferred north-westerly strike. The northwest structural control is evident not only at outcropscale but is also reflected in the northwest alignment of intrusives and the three centers ofmineralization in the district, Verde, Pancho and Guanaco.11
