Magnetic sands are just what they suggest--i.e., any fluvial (river sediments) or glacial (tills, etc.) or lacustrine (lake) or beach sediments which contain silica (sands) and are magnetic (usually due to also containing the mineral magnetite or ilmenite).

A timely question--since Montello is drilling in areas which may have (based on public maps) over 150 meters of fluvial and till sediments.

If Montello's exploration staff does not know how to distinguish magnetic sands from kimberlite geophysical signatures, one may expect very poor drill results. Hopefully Montello's geologists aren't trying to interpret what are very subtle differences in geophysical signatures--usually an experienced mining geophysicist is required to make those types of detailed interpretations.

Good Luck, T.

P.S. FYI, Ashton's Buffalo Head kimberlite discoveries have largely been made in areas of thin or no till/fluvial sediments. Ashton's geophysicists are very good and do know how to interpret their geophysics.
