JORC

The Australasian Code for Reporting of ExplorationResults, Mineral Resources and Ore Reserves sets out minimum standards, recommendations and guidelines for Public Reportingin Australasia of Exploration Results, Mineral Resources and Ore Reserves.

Main principles governing the operationandapplication of the JORC Code are:
* Transparency: clear and unambiguous information to understand the report.
* Materiality:all the relevant information which investors and theirprofessional advisers would reasonably require, andreasonably expect to find in the report.
* Competence: Public Report basedon work that is the responsibility of qualifiedand experienced persons.

The Code isapplicable to all solid minerals, including diamonds, other gemstones, industrial minerals and coal,for which Public Reporting of Exploration Results, Mineral Resources and Ore Reserves is required by theAustralian and New Zealand Stock Exchanges

‘Competent Person’:
* Is a Member of The Australasian Institute of Mining and Metallurgy,or of the Australian Institute of Geoscientists, or of a‘Recognised Overseas Professional Organisation’ (‘ROPO’).
* Must have a minimum of 5 years of experience which is relevant to the mineralization and type of deposit under consideration and to the activity which that person is undertaking. (Ex. Exploration, estimation and evaluation of mineral resources, estimation and evaluation of ore reserves).

The Exploration Results may or may not be part of aformal declaration of Mineral Resources or Ore Reserves.The reporting of such information is common in the early stages of exploration when the quantity of data available is generally not sufficient to allow any reasonableestimates of Mineral Resources.

A Mineral Resource is a concentration or occurrence of material of intrinsic economic interest in theEarth’s crust in such form, quality andquantity that there are reasonable prospects for eventual economicextraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resourceare known, estimated or interpreted from specificgeological evidence and knowledge.A Mineral Resource is a realistic inventory ofmineralisation which, under assumed and justifiabletechnical and economic conditions, might becomeeconomically extractable.
* InferredMineralResource: part of a Mineral Resource for which tonnage, grade and mineral contentcan be estimated with a low level of confidence. It is inferred from geological evidence and assumed but notverified geological and/or grade continuity. It is based on information gathered through appropriatetechniques from locations such as outcrops, trenches, pits,workings and drill holes which may be limited or of uncertain quality and reliability.
* Indicated Mineral Resource: part of a MineralResource for which tonnage, densities, shape, physicalcharacteristics, grade and mineral content can beestimated with a reasonable level of confidence. It isbased on exploration, sampling and testing information gathered through appropriate techniques fromlocationssuch as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriatelyspaced to confirm geological and/or grade continuity butare spaced closely enough for continuity to be assumed
* Measured Mineral Resource: part of a MineralResource for which tonnage, densities, shape, physicalcharacteristics, grade and mineral content can be estimated with a high levelof confidence. It is basedon detailed and reliable exploration, sampling and testing information gathered through appropriate techniquesfrom locations such as outcrops, trenches, pits, workings and drill holes. The locations are spaced closely enough to confirm geological and grade continuity.

Reports and statements shouldcontinue to refer to the appropriate category of Mineral Resources...
