You might forward that definition to the folks at ASPA, they did not seem to know the difference in that "report". They talk about dumps and tailings interchangeably as though it is the same material. Those con-men (Lowenthal, Blom, and Lumb) have put their names to some pretty ridiculous statements over the years, hard to believe they have any legitimate mining backgrounds at all.
Ooops, never mind, ASPA has gone dark - nobody home.
