Risk Assessment - Considerations
• Objectives of project and opportunities
• Tolerability of risks to others
• Whether a risk needs treatment
• Deciding whether risk can be
accepted
• Whether an activity should be
undertaken
• Priorities for treatment

Mining Management Plans Summary
• MMP’s are required as part of and application for an
Authorisation.
• The MMP need to be updated every 12 months for
ongoing operational activities.
• The MMP must include a security cost estimate.
• The MMP is auditable and stand alone document.
• The MMP is a planning document and needs to be
comprehensive enough to be read by anyone on site
giving them an understanding of the activities,
obligations and commitments of the project.
