Probable Mineral Reserve

A ‘Probable Mineral Reserve’ is the economically mineable part of an Indicated, and in

some circumstances a Measured Mineral Resource demonstrated by at least a Preliminary

Feasibility Study. This Study must include adequate information on mining, processing,

metallurgical, economic, and other relevant factors that demonstrate, at the time of

reporting, that economic extraction can be justified.

Proven Mineral Reserve

A ‘Proven Mineral Reserve’ is the economically mineable part of a Measured Mineral

Resource demonstrated by at least a Preliminary Feasibility Study. This Study must

include adequate information on mining, processing, metallurgical, economic, and other

relevant factors that demonstrate, at the time of reporting, that economic extraction is

justified.

Application of the Proven Mineral Reserve category implies that the Qualified Person has

the highest degree of confidence in the estimate with the consequent expectation in the minds of

the readers of the report. The term should be restricted to that part of the deposit where

production planning is taking place and for which any variation in the estimate would not

significantly affect potential economic viability.
