Mineral Resource <strong>and</strong> Mineral ReservedefinitionsSAMREC Code – The South African Code for Reportingof Mineral Resources <strong>and</strong> Mineral Reserves sets outminimum st<strong>and</strong>ards, recommendations <strong>and</strong> guidelines forpublic reporting of exploration results, Mineral Resources<strong>and</strong> Mineral Reserves in South Africa. SAMREC wasestablished in 1998 <strong>and</strong> is modelled on the AustralasianCode for Reporting of Mineral Resources <strong>and</strong> OreReserves (JORC Code). An updated version of SAMRECwas published in 2007.In terms of SAMREC, a Competent Person is one whois registered with the South African Council for NationalScientific Professions (SACNASP), the EngineeringCouncil of South Africa (ECSA) or the South AfricanCouncil for Professional L<strong>and</strong> Surveyors <strong>and</strong> TechnicalSurveyors (PLATO), or is a member of or Fellow of theSAIMM, the GSSA or a recognised overseas professionalorganisation (ROPO). A complete list of such recognisedorganisations is promulgated by the SSC from time totime. The Competent Person must comply with theprovisions of the relevant promulgated acts. A CompetentPerson must have a minimum of five years’ experiencerelevant to the style of <strong>mineral</strong>isation <strong>and</strong> type of depositor class of deposit under consideration <strong>and</strong> to the activitythey undertake. If the Competent Person is estimatingor supervising the estimation of Mineral Resources,the relevant experience must be in the estimation,assessment <strong>and</strong> evaluation of Mineral Resources. Ifthe Competent Person is estimating or supervising theestimation of Mineral Reserves, the relevant experiencemust be in the estimation, assessment <strong>and</strong> evaluationof Mineral Reserves. Persons called upon to sign as aCompetent Person must be clearly satisfied in theirown minds that they are able to face their peers <strong>and</strong>demonstrate competence in the commodity, type ofdeposit <strong>and</strong> situation under consideration.A Mineral Resource is a concentration (or occurrence)of material of economic interest in or on the earth’scrust in such form, quality <strong>and</strong> quantity that there arereasonable <strong>and</strong> realistic prospects for eventual economicextraction. The location, quantity, grade, continuity <strong>and</strong>other geological characteristics of a Mineral Resourceare known, estimated from specific geological evidence<strong>and</strong> knowledge, or interpreted from a well-constrained<strong>and</strong> portrayed geological model. Mineral Resources aresubdivided, in order of increasing confidence in respectof geoscientific evidence, into Inferred, Indicated <strong>and</strong>Measured categories.An Inferred Mineral Resource is that part of a MineralResource for which tonnage, grade <strong>and</strong> <strong>mineral</strong> content canbe estimated with a low level of confidence. It is inferred fromgeological evidence <strong>and</strong> assumed but not verified geological<strong>and</strong>/or grade continuity. It is based on information gatheredthrough appropriate techniques from locations such asoutcrops, trenches, pits, workings <strong>and</strong> drill holes that maybe limited or of uncertain quality <strong>and</strong> reliability.An Indicated Mineral Resource is that part of aMineral Resource for which tonnage, densities, shape,physical characteristics, grade <strong>and</strong> <strong>mineral</strong> content canbe estimated with a reasonable level of confidence. It isbased on exploration, sampling <strong>and</strong> testing informationgathered through appropriate techniques from locationssuch as outcrops, trenches, pits, workings <strong>and</strong> drill holes.The locations are too widely or inappropriately spaced toconfirm geological <strong>and</strong>/or grade continuity but are spacedclosely enough for continuity to be assumed.A Measured Mineral Resource is that part of a MineralResource for which tonnage, densities, shape, physicalcharacteristics, grade <strong>and</strong> <strong>mineral</strong> content can beestimated with a high level of confidence. It is based ondetailed <strong>and</strong> reliable exploration, sampling <strong>and</strong> testinginformation gathered through appropriate techniques fromlocations such as outcrops, trenches, pits, workings <strong>and</strong>drill holes. The locations are spaced closely enough toconfirm geological <strong>and</strong> grade continuity.A Mineral Reserve is the economically mineable materialderived from a Measured <strong>and</strong>/or Indicated MineralResource. It is inclusive of diluting materials <strong>and</strong> allowsfor losses that may occur when the material is mined.Appropriate assessments, which may include feasibilitystudies, have been carried out, including considerationof, <strong>and</strong> modification by, realistically assumed mining,metallurgical, economic, marketing, legal, environmental,social <strong>and</strong> government factors. These assessmentsdemonstrate at the time of reporting that extraction isreasonably justified. Mineral Reserves are subdividedin order of increasing confidence into Probable MineralReserves <strong>and</strong> Proved Mineral Reserves.A Probable Mineral Reserve is the economically mineablematerial derived from a Measured <strong>and</strong>/or Indicated MineralResource. It is estimated with a lower level of confidencethan a Proved Mineral Reserve. It is inclusive of dilutingmaterials <strong>and</strong> allows for losses that may occur when thematerial is mined. Appropriate assessments, which mayinclude feasibility studies, have been carried out, includingconsideration of, <strong>and</strong> modification by, realistically assumedmining, metallurgical, economic, marketing, legal,environmental, social <strong>and</strong> governmental factors. Theseassessments demonstrate at the time of reporting thatextraction is reasonably justified.A Proved Mineral Reserve is the economically mineablematerial derived from a Measured Mineral Resource. It isestimated with a high level of confidence. It is inclusiveof diluting materials <strong>and</strong> allows for losses that may occurwhen the material is mined.
