QA/QC Statement—Dorado Project Drill Samples
All of Angold Resources’ drill sample assay results have been independently monitored through a quality assurance/quality control (“QA/QC”) protocol which includes the insertion of blind standard reference materials, blanks, and duplicates at regular intervals. Logging and sampling of the Dorado drill samples were completed at Angold’s core handling facilities located in Copiapo, Chile. Drill core was diamond sawn on site and half drill-core samples were securely transported to ALS Laboratories’ (“ALS”) sample preparation facility in Copiapo.
Gold content was determined by fire assay of a 50-gram charge with atomic absorption finish (ALS method Au-AA24). Thirty-three other elements were analyzed by ICP methods with four-acid digestion (ALS method ME-ICP61m). ALS Laboratories is independent of Angold Resources and its facilities are ISO 17025 accredited. ALS also performed its own internal QA/QC procedures to assure the accuracy and integrity of results. Parameters for ALS’ internal and Angold’s external blind quality control samples were acceptable for the samples analyzed. Angold is not aware of any drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of its drill results data.
