Verification of a consignment typically includes the confirmation of the source or origin, the legitimacy and ownership.
The Assay and sample selection devised are done comprising of the following criteria:
- The sample selection methodologies we formulated produce a sample with a predictive mathematical probability of 99.975% and being representative of the consignment. This method of statistical sampling table derived from the application of the MILITARY STANDARD 105E (ANSI/ASQC Z1.4, ISO 2859) to establish the random sampling plan for a particular survey Lot of a Tranche which results in an Accepted Quality Level (AQL) of 0.025% (99.975% probability of detecting any anomalies).
- To obtain a very high degree of accuracy with regards to the purity level of samples, the assaying techniques of the selected samples include, but not limited to, XRF (X Ray Spectrometry), Sonic and Thermal technologies, Fire Assay as well as Specific gravity methods. Depending on source format, the Dancor Process™ could also be utilized. Combinations of assay techniques could also be used.
