In theory, very fine sediment sampling (<53 microns) has the potential to improve the usefulness of stream sediment data for gold. The key theoretical advantages over traditional techniques are less local sample site variation, improved reproducibility, and the potential to preferentially define anomalies associated with significant bedrock mineralization. An orientation survey is required to test the actual effectiveness of these techniques and to establish practical sampling and processing procedures.
