Cumulative effects assessment

1. Cumulative effects assessment

2. Cumulative effects assessment Approach Scoping: focus on VECs and VSECs where potential for cumulative effects existed - regardless of whether the effect was significant identified past, present and potential future projects identified residual effects for other projects identified the “zone of influence” for effects confirmed potential cumulative effects scope did not include a study of the cumulative effects of accidents and malfunctions

11. Cumulative effects assessment Approach Mitigation: appropriate mitigation identified, as required Significance compare effects against known or derived thresholds and land use plan expectations Follow-up program designed as needed

12. Cumulative effects assessment Potential cumulative effects

13. Cumulative effects assessment Potential for other projects to use infrastructure Analysis 1 in 1000 exploration projects result in a mine 2% chance that the construction of a road will spawn the development of a mine in the north within a 300 km radius Result maximum 5% chance that a mine will result because of Zinifex infrastructure i.e., 1 or 2 mines

14. Cumulative effects assessment Results no significant adverse cumulative effects identified identified cumulative effects can be managed through project-specific mitigation and adjusted through monitoring
