An analytical laboratory is the heart of a resource delineation program. All economic parameters and production design decisions are ultimately based upon analyses from the laboratory. An external examiner who can spot laboratory shortcuts or QC deficiencies should periodically audit a laboratory and correct these before poor practices become entrenched. All publicly traded Canadian mineral exploration companies must now review and comment upon the commercial analytical laboratories used in resource assessment. Smee and Associates has thirty years of experience in operating and auditing geochemical and assay laboratories, and has audited more than 80 laboratories throughout the world in the past two years.
