"Gangue" General term for minerals that are not considered to be of economic significance
"GDP" Gross Domestic Product; total value of goods produced and services provided in a country in one year
"Geochemistry" Prospecting techniques which measure the content of specified metals in soils and rocks; sampling defines anomalies for further testing
"Geological losses" Losses to account for all necessary adjustments with respect to faults, potholes, dykes etc. Incorporated into the Mineral Resource estimates

"HDPE" High Density Polyethylene
"Hydrogeology" The study of water flow and distribution underground
"Indicated Mineral Resource" The part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through
appropriate techniques from locations such as outcrops, trenches, pits, workings and drill-holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be
assumed
"Inferred Mineral Resource" The part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information
gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be limited or of uncertain quality and reliability
"IRR" Internal Rate of Return is a capital budgeting method used by firms to decide whether they should make long term investments; the IRR is defined as any discount rate that results in a net present value of zero, and is usually interpreted as the expected
return generated by the investment

"Lower Palaeozoic" The earliest of the three geological eras, from 541 to 252 million years old
"m" Metre
"Ma" million years
"Malachite" A bright green copper carbonate hydroxide found in the oxide zone of copper deposits
"Measured Mineral Resource" That part 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 appropriate techniques from locations such as outcrops, trenches, pits, workings and drillholes. The locations are spaced closely enough to confirm geological and grade continuity
"Modifying Factor" Considerations made when converting mineral resources to ore reserves. Includes mining, processing, infrastructure and environmental factors
"Metasomatism" The alteration of the chemical composition of a rock by hydrothermal or other fluids
"Micro" Prefix that divides a basic unit by 1 million or multiplies it by 106; a prefix meaning small; when modifying a rock name, it signifies fine-grained, as in microgranite
"Mill" Equipment used to grind crushed rocks to the desired size for mineral extraction
"Mineral Resource" A concentration or occurrence of material of intrinsic economic interest in or on the earth's crust in such a form that there are reasonable prospects for the 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 into Inferred Mineral Resource, Indicated Mineral Resource and Measured Mineral Resource categories
"Mineral Resource Estimation" Set of computerised processes and procedures used to derive estimates of in-situ tonnages and grades of a mineral deposit
"Mineralisation" Process of formation and concentration of elements and their chemical compounds within a mass or body of rock
"mm" Millimetre, one thousandth of a metre
"Moz" Million troy ounces
"MPa" Unit to measure rock strength, Megapascal
"Mt" Million tonnes
"NPV" Net Present Value is a standard method in finance of capital budgeting-the planning of long-term investments; using the NPV method a potential investment project should be undertaken if the present value of all cash inflows minus the present value of all
cash outflows (which equals the net present value) is greater than zero
"Open pit" A surface mine
"Orebody" Mining term to define a solid mass of mineralised rock which can be mined profitably under current or immediately foreseeable economic conditions "ore" a mineral deposit that can be extracted and marketed profitably
"Ore Reserves" An Ore Reserve is the economically mineable part of a Measured Mineral Resource and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies
at Pre-Feasibility or Feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified
"Ounce" or "oz", 1 troy ounce = 31.1035 grammes
"Oxides" Minerals that occur in predominantly oxide based compounds
"pregnant leach solution" the copper-bearing solution used in the SX process
"ppb" Parts per billion
"ppm" Parts per million
"Porphyry" A term for an intrusive igneous rock consisting of large grained crystals. Common host of copper deposits
"Probable Ore Reserves" The economically mineable part of an Indicated Mineral Resource, and in some circumstances, a Measured Mineral Resource. The confidence in the Modifying Factors applying to a Probable Ore Reserve is lower than that applying to a Proved Ore Reserve
"Proved Ore Reserves" The economically mineable part of a Measured Mineral Resource. A Proved Ore Reserve implies a high degree of confidence in the Modifying Factors

"Scoping Study" A study that includes an economic analysis of the potential viability of mineral resources taken at an early stage of the project prior to the completion of a pre-feasibility study. A Scoping Study may be based on Measured, Indicated Mineral Resource, or
Inferred Mineral Resources or a combination of any of these and include disclosure of forecast mine production rates and may contain capital costs to develop and sustain the mining operation, operating costs. A Scoping Study would have limited site
specific data in respect of key operating assumptions and would only address certain disciplines on a high level fatal flaw basis. Both the contingency (>30%) and accuracy/sensitivity (±30%) associated with key assumptions are generally higher than that
assumed for PFSs. Key deliverables of a Scoping Study would include the determination of sufficiently positive technical and economic outcomes such that advancement to PFS level is warranted. A Scoping Study is preliminary in nature, in that it may also
include Inferred Mineral Resources
"Shaft" Vertical or inclined excavation into mine workings
"Silver" or "Ag" A soft, white, precious metal with very high thermal and electrical conductivity, chemical symbol Ag
"Smelting" A high temperature pyrometallurgical operation conducted in a furnace, in which the valuable metal is collected to a molten matte phase and separated from the gangue components that accumulate in a less dense molten slag phase
