MINERAL RESOURCES and ORE RESERVES

Xstrata Alloys has adopted the 2004 Australasian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves (the JORC Code) as its mandatory normal for the estimation of public reporting of Mineral Resources, Ore Reserves and Exploration Outcomes.

Mineral Ore Plant

The estimation procedure is additional based on the Xstrata Alloys procedure "HSEC-G-08-The Process for the estimation of Mineral Resources and Ore Reserves".

The Ore Reserves and Mineral Resources are declared as in the 30th of June 2008, unless stated otherwise for the certain commodity.

This statement covers four ore sorts currently being mined and beneficiated by Xstrata Alloys.

The ore forms are:

Chromitite

Vanadiferous Magnetite

Quartzite

PGE mineralized chromitite ore

The Ore Reserve and Mineral Resource data in the tables on the following pages is based on info compiled by Competent Persons (as defined by the JORC and SAMREC Codes).

The Competent Person initials have been included immediately after each mine or project for which the Competent Individual have been responsible. Every single in the Competent Persons has the suitable qualified membership and also the relevant expertise in relation for the Mineral Resources and/or Ore Reserves getting reported by them to qualify as a Competent Individual as defined in the JORC and SAMREC Codes. The Competent Persons have consented for the inclusion inside the report with the matters according to their data inside the form and context in which it appears. Copies from the consenting letter are kept using the legal department of Xstrata Alloys.

Metric units are made use of all through. All data is presented on a 100% basis. All tonnage and grade facts has been rounded to reflect the relative uncertainty inside the estimates; there may perhaps therefore be small differences inside the totals. Mineral Resources are reported inclusive of those Mineral Resources modified to create Ore Reserves.

Commodity prices and exchange rates made use of to estimate the economic viability of Ore Reserves are according to long term forecasts applied at the time the estimate was calculated.

The detail background data for the estimation in the Mineral Resources and Ore Reserves is usually requested from Xstrata Alloys.

Mineral crusher and ore crusher

In the mineral resources mining indsutry, SBM can can supply you mineral crusher or ore crusher employed for crushing mineral resources in mining plants. For example mineral jaw crusher is the most widely employed crushing equipment in primary crushing plants. The secondary crusher machinery consists of gyratory crusher or cone crusher with spring, hydraulic, hcs90 forms.

Definitions

The following definitions (as per the JORC Code 2004), have been applied in estimating the Ore Reserves and Mineral Resources position of the Xstrata Zinc disclosed inside this document.

Mineral Resource: a concentration or occurrence of material of intrinsic economic interest in or on the Earth's crust in such form, top quality and quantity that you'll find reasonable prospects for eventual economic extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are identified, estimated or interpreted from certain geological evidence and information. Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories.

Inferred Mineral Resource: that part of a Mineral Resource for which tonnage, grade and mineral content material might be estimated having a low level of confidence. It is actually inferred from geological evidence and assumed but not verified geological and/or grade continuity. It's based on details gathered by means of proper tactics from places like outcrops, trenches, pits, workings and drill holes which may possibly be limited or of uncertain quality and reliability.

Indicated Mineral Resource: that component of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content may be estimated with a reasonable degree of confidence. It really is depending on exploration, sampling and testing info gathered through proper methods from places like outcrops, trenches, pits, workings and drill holes. The places are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely adequate for continuity to be assumed.

Measured Mineral Resource: that component of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content may be estimated using a high degree of confidence. It truly is according to detailed and reliable exploration, sampling and testing data gathered by means of proper tactics from places such as outcrops, trenches, pits, workings and drill holes. The places are spaced closely enough to confirm geological and grade continuity.

Ore Reserve: the economically mineable portion of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined.

Appropriate assessments and scientific studies have been carried out, and contain consideration of and modification by realistically assumed mining, metallurgical, economic, marketing and advertising, legal, environmental, social and governmental aspects. 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.

Probable Ore Reserve: the economically mineable part of an Indicated, and in some circumstances, a Measured Mineral Resource. It consists of diluting materials and allowances for losses which might occur when the material is mined. Proper assessments and studies have been carried out, and contain consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental aspects. These assessments demonstrate in the time of reporting that extraction could reasonably be justified.

Proved Ore Reserve: the economically mineable part of a Measured Mineral Resource. It consists of diluting supplies and allowances for losses which may take place when the material is mined. Appropriate assessments and research have been carried out, and consist of consideration of and modification by realistically assumed mining, metallurgical, economic, marketing and advertising, legal, environmental, social and governmental factors. These assessments demonstrate in the time of reporting that extraction could reasonably be justified.

Mineral processing plants

Mineral processing plants are mainly consisted of crusher, grinding machines, screens, feeders, conveyors and so on. In some situations, we need mineral resources' powder for industrial usage, so we will need stone milling equipments for grinding procedure. Mineral mill or mineral grinders primarily involve ball mill , Raymond grinder machine, vertical roller mill, trapezium grinding mill and so on.
