Mr. Frank Sheridan:

On the question of substances, the Schedule to the Bill lists the minerals to be covered by the terms of the Bill in the course of prospecting or mining. There is a degree of flexibility provided for as there may well be substances there that we are just not aware of. This is, after all, an exploratory activity. The definition at the start of the Bill is to cover all minerals and the purpose of the Schedule is to itemise as many of those as possible and it is largely to do with the uncertainty as to the occurrence of those minerals in the terrain.
