Classification of Reserves

Question 1

What are Inferred resources?

Answer 1

defined where tonnage, grade and mineral
content can be estimated with a low level of confidence and when
there are insufficient data to confirm continuity of the resource

Question 2

What are indicated resources

Answer 2

Indicated resources are defined where tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence and when there are insufficient
data to confirm continuity of the resource, but sufficient where the mineralisation’s continuity can be assumed.

Question 3

what are measured resources?

Answer 3

Measured resources are defined where tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a high level of
confidence and sufficient data are available to confirm continuity of the mineralisation.

Question 4

what is an ore reserve?

Answer 4

An ore reserve is defined as the economically mineable part of a measured or indicated mineral resource. It includes diluting materials and allowances for losses, which may occur when the material is
mined.
