Technical Report for the Maricunga Gold Mine - Kinross Gold

Kinross Gold CorporationMaricunga Mine Technical Report14.2 Pre-2002 Data Verification14.2.1 Collar DataVerification of the historic collar data identified one error of note. Collar coordinates of drillholes completed between 1986 and 1987 did not match the coordinates recorded on originalsurvey sheets. This error was also corrected.14.2.2 Survey DataMuch of the historical downhole survey data could not be located. The limited downholesurvey data that was located was used to verify the data in the IDB. No significant errorswere noted.14.2.3 Lithology, Alteration, Oxidation, Vein and Mineralization Data:Ten percent of all lithology, alteration, oxidation, vein description and mineralization data forthe 1997 – 1998 drill campaign was verified as this data was collected using field practicesand logging formats consistent with the 2002-2003 effort.14.2.4 Analytical DataTen percent of the historical analytical results in the IDB were verified against original assaycertificates. Rare errors were detected during the verification process but these were almostexclusively related to the recording of results below the detection limit for successiveprograms.14.3 2002-2003 Data Verification14.3.1 Collar DataPrior to entering collar data into the database, collar locations were visually checked forobvious errors such as transposed northings and eastings. Once entered, collar coordinatesand hole lengths were extracted and printed for direct comparison to the original surveycertificates. The collar coordinates were compared against the signed surveyors’ certificateand the hole length were checked against the geologists’ logs. Three independent checks of54
