A nickel-copper ore was obtained from a North American concentrator. This ore was crushed to minus 2 mm (10 mesh), blended, and split into 1 kg lots. Table 1 shows the external reference distribution for the ore. All the relative standard distributions (RSD) were less than 5%, which means that the sample was well blended.
