Twyman, geological consultant, has been on site to start the programme and reports finding several areas of artesanal gold mining of eluvial/colluvial material (eluvial material is surface material that is derived from the weathering (rotting) of bedrock and colluvial material is eluvium that has moved down-slope but is probably not very distant from its source).
However, some also were probably found in loose eluvium just above a pipe or in colluvial ground adjacent to it.
