Laminae

comprising of layers of minerals;

Lenticular

resembling in shape the cross section of a lens;

MDM

Metallurgical Design and Management;

Measured resource

that portion of a mineral resource for which tonnage, densities, shape, physical characteristics,

grade and mineral content can be estimated with a high level of confidence. It is based

on detailed and reliable exploration, sampling and testing information gathered through

workings and drill holes. The locations are spaced closely enough to confirm geological

and/or grade continuity;

Metamorphism

alteration of rocks and minerals by a combination of heat, pressure and chemical processes

over a long time period;

Metasediment

a sedimentary rock that has undergone metamorphism;

Metavolcanic

a volcanic rock that has undergone metamorphism;

Mineral resource

a concentration or occurrence of material of intrinsic economic interest in or on the earth's

crust in such a form and quantity that there are reasonable prospects for eventual economic

extraction. The location, quantity, grade, geological characteristics and continuity of a

mineral resource are known, estimated or interpreted from specific geological evidence

and knowledge. Mineral resources are sub-divided, in order of increasing geological

confidence, into inferred, indicated and measured categories;

Moz

million troy ounces;

Mt

million metric tonnes;

Ore reserve

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.

Appropriate assessments, which may include feasibility studies, have been carried out

and include consideration of and modification by realistically assumed, mining, metallurgical,

economic, marketing, legal, environmental, social and governmental factors. These

assessments demonstrate at the time of reporting that extraction could reasonably be

justified. Ore reserves are sub-divided in order of increasing confidence into probable

ore reserves and proved ore reserves;

Pegmatites

very coarse grained igneous rock usually granitic in composition;

PL

Prospecting licence;

PLR

Prospecting licence (reconnaissance);

Porphyry

a rock with conspicuous crystals in a fine-grained groundmass;

Probable ore reserve

the economically mineable part of an Indicated, and in some circumstances measured

mineral resource, it includes diluting materials and allowances for losses which may occur

when the material is mined. Appropriate assessments, which may include feasibility studies,

have been carried out and include consideration of and modification by realistically

assumed, mining, metallurgical, economic, marketing, legal, environmental, social and

governmental factors. These assessments demonstrate at the time of reporting that

extraction could reasonably be justified;

Proved ore reserve

the economically mineable part of a measured mineraI resource. It includes diluting

materials and allowances for losses which may occur when the material is mined.

Appropriate assessments, which may include feasibility studies, have been carried out

and include consideration of and modification by realistically assumed, mining, metallurgical,

economic, marketing, legal, environmental, social and governmental factors. These

assessments

demonstrate at the time of reporting that extraction could reasonably be justified;

Lower Proterozoic

era of geological time between 2.5 x 109 and 1.8 x 109 years before the present;

Regolith

fragmental and unconsolidated rock material overlying bedrock;

Resistivity

electrical property of rock;

ROM

Run of Mine - equivalent to normal feed ore from mining operations;

RP

Reconnaissance Permit;

Sedimentary

sourced from erosion of other rocks;

Shale

fine grained sedimentary rock;

Stripping ratio

ratio of waste material to ore material needed to be moved in an open pit mine;

Tailings

finely ground waste rock from which valuable minerals or metals have been extracted;

Tectonic

deformation within the earth’s crust;

tpm

metric tonnes per month;

US$

United States dollar;

US$m

million United States dollars;

US$/oz

United States dollar per ounce;

Weathered

rock broken down by erosion;

Whittle 4D

an optimisation computer programme used for open pit mine design.
