OZ Minerals organisational and management structure

OZ Minerals sustainability governance

Board and committees

Responsibility for our strategic approach to sustainability lies with the OZ Minerals Board. The Board strives to ensure that it is comprised of strongly performing individuals of utmost integrity whose complementary skills, experience, qualifications and personal characteristics are suited to OZ Minerals’ needs.

OZ Minerals’ Constitution provides for a minimum of three and a maximum of fifteen directors. The Board has determined that currently the appropriate number of directors is eight, including the CEO and seven independent non-executive directors.

To facilitate the execution of its responsibilities, the Board’s Committees provide a forum for a more detailed analysis of key issues. The current Board committees are the Audit Committee, Sustainability Committee and the Nomination and Remuneration Committee.

The Sustainability Committee’s role is to assist the Board in the effective discharge of its responsibilities in relation to safety, health, environmental and community issues across the company and the oversight of risks relating to these issues and other non-financial risks.

A profile of each director, including their skills, experience, relevant expertise and special responsibilities is available in our Annual Report.

Senior management

Responsibility for OZ Minerals business processes and sustainability performance lies with the CEO, Andrew Michelmore, supported by the executive management team. The CEO’s performance is measured against detailed key performance indicators (KPIs) relating to values and governance, economic, social and environmental performance. This forms the basis of remuneration and short-term incentives (STIs).

These KPIs cascade through to all of the CEO’s direct reports, whose performance is measured against KPIs relating to economic, social and environmental performance within their particular area of responsibility. This cascade of KPIs from manager to direct report flows throughout the company.

Special responsibilities lie with the Executive Sustainability Committee, including the Chief Operating Officer, Company Secretary and General Counsel, the Executive General Manager (EGM) Business Support, EGM Projects and Technical Services, EGM Exploration and the General Manager (GM) Sustainability. All OZ Minerals general managers are accountable for values and governance, economic, social and environmental performance within their particular area of responsibility.

A component of the review of the OZ Minerals performance management system that is currently underway is to review existing KPIs and ensure specific sustainability KPIs cascade consistently throughout all levels of the company.
