Given a maximum (overestimate) contamination from clays of 5% (from Sr mass balance calculations), the potential deviation of clay-sourced Nd (NdTD) on the weak leach is estimated. In all cases, the value is less than the 2 sigma measurement error of 0.5, thus the potential for clay contamination can be ignored. |
