To ensure the reliability of the analyses, in addition to the quality control specific to the SGS BAMAKO laboratory, a quality control protocol has been put in place by the geology team at the NLMC project level. It consists of the random insertion of 6% standard samples, duplicate samples and blank control samples, during sample taking, with all samples sent to the laboratory (on each 47 sample we insert 3 QAQC samples).
