Mining Act 1978

For the purposes of this Division, the surface of the Earth shall be deemed to be divided —

by the meridian of Greenwich and by meridians that are at a distance from that meridian of 1, or a multiple of 1, minute of longitude; and

by the equator and by parallels of latitude that are at a distance from the equator of 1, or a multiple of 1, minute of latitude,

by portions of 2 of those meridians that are at a distance from each other of 1 minute of longitude; and

by portions of 2 of those parallels of latitude that are at a distance from each other of 1 minute of latitude.

For the purposes of this Division —

a graticular section that is wholly within the State constitutes a block; and

if part of a graticular section is within the State that part of the graticular section constitutes a block.

In this Division —

a reference to a graticular section that constitutes a block includes a reference to a graticular section part of which constitutes a block;

a reference to a part of a block includes a reference to 2 or more parts of the block;

a reference to a part of a graticular section includes a reference to 2 or more parts of the graticular section.

For the purposes of this Division each block shall be identified by reference to the number of the block on a plan held at the Department.

Without limiting section 9B(1A), a datum must be prescribed by the regulations for the purposes of the determination of the position on the surface of the Earth of a graticular section or a block.

Despite subsection (1), the meridians of longitude defining the eastern and western boundaries of a graticular section, and the parallels of latitude defining the northern and southern boundaries of a graticular section, are taken to be at a distance from each other that is other than 1 minute if required as a result of the prescription of a datum under subsection (4A).

In subsection (2) —
