Cautionary Note to US Investors – The SEC generally permits mining companies in their filings with the SEC to disclose only those mineral deposits that the company can economically and legally extract. Certain terms in this presentation, including “resource”, “measured resource”, “indicated resource”, “inferred resource” and “deposit”, would not generally be permitted in an SEC filing. The material denoted by such terms is not proven or probable Reserves as such terms are used in the SEC's Industry Guide 7, and there can be no assurance that BHP Billiton will be able to convert such material to proven or probable Reserves or extract such material economically. BHP Billiton urges investors to refer to its Annual Report on Form 20-F for the fiscal year ended June 30, 2007, for its most recent statement of mineral Reserves calculated in accordance with Industry Guide 7.

Competent Persons for Mineral Resources and Ore Reserves are named in the BHP Billiton Annual Report 2007, which can be viewed at www.bhpbilliton.com. Stuart Hayward, who is a member of AIG and a full time employee of BHP Billiton, and Shane O'Connell, who is a member of the AusIMM and a full time employee of BHP Billiton,  have the required qualifications and experience, are joint Competent Persons for the assessment of Mineral Resources at Olympic Dam, which has been reported in accordance with the Australasian Code for Reporting of Mineral Resources and Ore Reserves, December 2004 (the JORC Code).  Stuart Hayward and

Shane O'Connell verify that the 2007 Mineral Resource data included in this document is based on and fairly reflects the information in the supporting documentation relating to Olympic Dam Mineral Resource.The Mineral Resource numbers prior to 2007 have been sourced from the publicly available Annual Reports for WMC and BHPBilliton.

Hsec design principles l.jpg
HSEC Design Principles

  • No ODX contractor or employee will make decisions based solely on economic grounds.

  • Project Teams are empowered to create initiatives to continuously improve HSEC performance.

  • Designs will meet regulatory requirements and BHP Billiton Standards.

  • The principles of ALARP apply in all designs.

  • The Hierarchy of Control applies in all designs


Hse in design across the project l.jpg
HSE IN DESIGN ACROSS THE PROJECT

  • HSE is inculcated into all facets of engineering design.

  • HSE in Design activities and supporting documents have been developed for use throughout the project lifecycle.

  • HSE in Design is not exclusively about conformance with risk assessment processes (e.g. HAZOP). These processes are certainly necessary and important; however, they serve only to ensure that HSE issues have been addressed earlier in the design process.


Hse in design across the project15 l.jpg
HSE IN DESIGN ACROSS THE PROJECT

  • The Project Team's approach to HSE in Design is consistent with the "National OHS Strategy 2002 – 2012"

  • One of five National Priorities set by the ASCC (formerly NOSHC) is "Eliminate hazards at the design stage".

  • ODX activities relating to HSE in Design aim to influence the behaviours and actions of all persons involved with engineering design so they are committed to the;

    • Elimination of hazards

    • Application of Leading Practice

    • Application of FRCP requirements

    • Application of design related key learning's from Significant Incidents


Hse design criteria l.jpg
HSE DESIGN CRITERIA

  • The ODX HSE Design Criteria establishes a set of philosophies and criteria which apply to all design decisions on the ODX Project.

  • The document provides guidance to designers on the fundamental principles of HSE in Design (based on the concept of Damaging Energy) and how to manage damaging energy types through design.

  • Information is supplemented by photos of 'Leading Practice' as well as poor examples and design features to avoid.


Hse design criteria17 l.jpg
HSE Design Criteria

  • Work teams are empowered to review significant incidents and hazards and develop solutions for eliminating these from the work place.

  • Significant Incident Elimination Posters are developed.

Summary

  • Our goal is Zero Harm to our employees and contractors.

  • We will endeavour to eliminate hazards from our workplace by designing safe plant and equipment.

  • Mature organisations have a positive reporting culture of incidents and near misses that are critical for developing solutions for eliminating hazards from the work place

  • No decisions will be based solely on economic grounds.

  • The Hierarchy of Control will always apply.
