Pretty sure it's ironstone based. That region and further north at Wave Hill this ironstone forms Staurolites, which have a glazed surface formed from intrusion of either manganese, zinc or aluminium oxide. They're mainly associated with the abundant schist ranges in that region. If he has them close by, tell him to keep a look out for "Maltese Crosses", which are a much sought after stone in that region.

Cheers Wal.
