4E (equivalent to 3PGE+Au)

Refers to the sum of platinum, palladium, rhodium and gold, as determined by a fire assay method (typically by a lead collection procedure); notably there are various methods in operation at different laboratories and companies; these are not directly comparable. These fire assay methods typically under-measure the actual total platinum, palladium, rhodium and gold content

6E (equivalent to 5PGE+Au)

Refers to the sum of platinum, palladium, rhodium, ruthenium, iridium and gold as determined by a nickel sulphide collection fire assay procedure; this is considered to be the most accurate assay procedure, and results can usually be compared between laboratories

Resource and Reserve definitions

SAMREC Code

The South African Code for Reporting of Mineral Resources and Mineral Reserves sets out minimum standards, recommendations and guidelines for Public Reporting of Exploration Results, Mineral Resources and Mineral Reserves in South Africa. SAMREC was established in 1998 and modelled its Code on the Australasian Code for Reporting of Mineral Resources ore Reserves (JORC Code). An updated version of SAMREC was published in 2007.

In terms of SAMREC, a Competent Person is one who is registered with the South African Council for Natural Scientific Professions (SACNASP), the Engineering Council of South Africa (ECSA) or the South African Council for Professional and Technical Surveyors (PLATO), or is a member of or Fellow of the SAIMM, the GSSA or a Recognised Overseas Professional Organisation (ROPO). A complete list of such recognised organisations is promulgated by the SSC from time to time. The competent Person must comply with the provisions of the relevant promulgated Acts. A Competent Person must have a minimum of five years’ experience relevant to the style of mineralisation and type of deposit or class of deposit under consideration and to the activity they undertake. If the Competent Person is estimating or supervising the estimation of Mineral Resources, the relevant experience must be in the estimation, assessment and evaluation of Mineral Resources. If the Competent Person is estimating or supervising the estimation of Mineral Reserves, the relevant experience must be in the estimation, assessment and evaluation of Mineral Reserves. Persons called upon to sign as a Competent Person must be clearly satisfied in their own minds that they are able to face their peers and demonstrate competence in the commodity, type of deposit and situation under consideration.

Mineral Resource

A Mineral Resource is a concentration (or occurrence) of material of economic interest in or on the Earth’s crust in such form, quality and quantity that there are reasonable and realistic prospects for eventual economic extraction. The location, quantity, grade, continuity and other geological characteristics of a Mineral Resource are known, estimated from specific geological evidence and knowledge, or interpreted from a well constrained and portrayed geological model. Mineral Resources are subdivided, in order of increasing confidence in respect of geoscientific evidence, into Inferred, Indicated and Measured categories.

Inferred Mineral Resource

An Inferred Mineral Resource is that 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 that may be limited or of uncertain quality and reliability.

Indicated Mineral Resource

An Indicated Mineral Resource is that 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.

Measured Mineral Resource

A Measured Mineral Resource is 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. Working and drill holes. The locations are spaced closely enough to confirm geological and grade continuity.

Mineral Reserve

A Mineral Reserve is the economically mineable material derived from a Measured and/or Indicated Mineral resource, it is inclusive of diluting materials and allows for losses that may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out, including consideration of, and modification by, realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and government factors. These assessments demonstrate at the time of reporting that extraction is reasonably justified. Mineral Reserves are sub-divided in order of increasing confidence into Probable Mineral Reserves and Proved Mineral Reserves.

Probable Mineral Reserve

A Probable mineral Reserve is the economically mineable material derived from a measured and/or Indicated Mineral Resource. It is estimated with a lower level of confidence than a Proved Mineral Reserve. It is inclusive of diluting materials and allows for losses that may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out, including 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 is reasonably justified.

Proved Mineral Reserve

A Proved Mineral Reserve is the economically mineable material derived from a measured Mineral Resource. It is estimated with a high level of confidence. It is inclusive of diluting material and allows for losses that may occur when the material is mined. Appropriate assessments, which may include feasibility studies, have been carried out, including consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time reporting that extraction is reasonably justified.
