Technical Report for the Maricunga Gold Mine - Kinross Gold

Kinross Gold CorporationMaricunga Mine Technical Report9.0 MINERALIZATION9.1 VerdeGold 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. Approximately 80% of the stockwork veins aregenerally dark grey in color, finely banded, with magnetite. The remaining 20% areprincipally white quartz veins. Gold mineralization is postulated to have resulted from at least2 phases of mineralization, the first is a lower grade phase associated with copper andprobably the porphyry emplacement event. The second phase is a higher-grade gold onlyevent possibly associated with the structurally emplaced veinlet swarms and northwesttrending sheeted veinlet zones more evident in Verde East. Verde East and Verde Westcover an area of 1.4 km in length by 700 km in width. Drilling has identified goldmineralization to a depth of a 600 m.9.2 PanchoThe porphyritic diorite intrusives and intrusive breccias are the main hosts for mineralizedveins. Mineralization is also hosted by the volcanic rocks. The mineralization is commonlyrelated to the various geologic features listed below:• directly associated with the presence of B, A and T veinlets• in silicified zones, normally micro-granular and a dark grey color, with or without thepresence of magnetite• associated with intrusive breccias• in contact zones such as the contact between the intrusive breccia with the volcanicbreccia or the contact between the intrusive breccia and the diorite porphyryIn the porphyry the veins are present in stockwork or sheeted veins. They are generallysubvertical and have a strong, preferred north-westerly strike. The northwest structuralcontrol is evident not only at outcrop scale but is also reflected in the northwest alignment ofintrusives and the three centers of mineralization in the district, Verde, Pancho and38
