    2019-10-17  Rock chip sampling is sampling of exposed potentially mineral-bearing rocks. Chips are taken during initial mapping, and if promising results are returned, a subsequent soil sampling survey undertaken. Alternatively, in many cases, outcrops maybe either minor or non-existent, and soil sampling is a key next step for an exploration programme.
