Technical Report for the Maricunga Gold Mine - Kinross Gold

Kinross Gold CorporationMaricunga Mine Technical Report12.2 Core DrillingDrill core was received and laid out for logging and sampling at the core logging facility. Thefirst sample of each core hole was marked from the start of core recovery to the end of thefirst even meter. From that point, samples were laid out every 2.0 meters downhole. Samplenumbers were marked on the core box edges, accounting for number gaps for QA/QCsample insertion. Logged and marked boxes of whole core were transferred to the ALSChemex sample preparation facility where chain of custody was transferred from CMM toALS Chemex.CMM received the sawn core, in the original labelled boxes, from ALS Chemex aftersplitting. The half-cores were stored shipping containers at the Maricunga site. In all, tencontainers were used to store the half-core library.Core sample rejects are bagged in plastic, labelled and received from the ALS Chemexsample preparation facility. These bags are placed in cubic meter wooden bins. The binsare labelled according to hole number and sample range. The bins are stored beside thecore containers and are locked in a covered storage compound.The samples are representative of the mineralization intercepted at Pancho. The authorvisited the drill sites at a minimum once a month during the 2006 exploration. The author issatisfied that all established procedures were properly followed by the field staff.12.3 LoggingExperienced geologists logged the reverse circulation chips and drill core at Maricunga.Reverse circulation chips were typically logged at the drill while core was typically logged atthe core logging facility. All logging utilized standardized logging forms and a geologicallegend developed for the Verde and Pancho deposits. The legend has evolved from historicobservation and is consistent with both the regional and local geology. The legend andlogging records lithology, alteration, structure, geology, mineralization and oxidation (ofpyrite) for each two meter sample interval, reducing the geological descriptions to numeric oralphanumeric codes. Unique features not accounted for in the legend are noted in writtencomments. The legend stresses oxidation conditions of pyrite, veinlet mineralization,location and amount of magnetite and occurrence of typical porphyry alteration minerals.46
