Security – Chain of Custody and Quality Control
Two metre lengths of HQ core samples were halved with a diamond saw and bagged at the field facility. The bags were tied with plastic color-coded security ties. Sample bags were then placed in shipping boxes and couriered by company vehicle to the Acme Analytical Laboratories S.A. prep lab in Mendoza, Argentina. Samples are prepped and fire assayed at Acme facilities in Mendoza, Argentina. Part of the pulps is shipped by Acme to their lab in Santiago, Chile for further assaying. The Company employs a Quality Control program consisting of re-assaying in two different Assay Laboratories randomly selected coarse reject samples and pulps samples, and also insertion of a pulp standard samples, a coarse blank and a duplicate each 20 samples in the field.
