2. The Angas Zinc Project: Vegetation and visual impact The aim of this presentation is to provide stakeholders with a clear image of the process and outcomes of the Angas Zinc Project with respect to vegetation & visual amenity related issuesThe aim of this presentation is to provide stakeholders with a clear image of the process and outcomes of the Angas Zinc Project with respect to vegetation & visual amenity related issues –Current condition: vegetation, visual impact –Proposed development: changes to current vegetation lay out, proposed structural changes to site

3. The Angas Zinc Project: Vegetation and visual impact The construction of a mine will inevitably change the visual landscape of the site.The construction of a mine will inevitably change the visual landscape of the site. The goal is to achieve a positive visual impact during operations and on closureThe goal is to achieve a positive visual impact during operations and on closure

4. Vegetation survey Matt Rose: Natural StateMatt Rose: Natural State –Experienced native vegetation specialist, locally based –Recognised expertise in survey, cultivation, planting & maintenance of native vegetation

5. Revegetation Domains

6. Effluent ponds/Tuckers Swamp (Northern Domain) No operational impact on this DomainNo operational impact on this Domain –Effluent ponds/Tuckers Swamp –Significant remnant habitat: River Red Gums, Lignum shrub To be preserved in current conditionTo be preserved in current condition

7. Operating Domains (Central & Southern) Current quarry/proposed box cut, plant and TSF Site vegetation - severely degraded with respect to natural conditionSite vegetation - severely degraded with respect to natural condition –Broad-acre cropping – TSF area –Majority of vegetation introduced, weeds –Small remnant vegetation patches; native grasses –Only significant trees: Dryland Tea Trees

12. Revegetation Objective Objectives (short & long term)Objectives (short & long term) –Significant increase environmental benefit (SEB) –Remove feral habitat –Significantly reduce noise, dust –Improve habitat quality –Increase biodiversity –Significantly improve visual amenity

13. Revegetation Program Contouring sound barriers to mergeContouring sound barriers to merge Revegetation planningRevegetation planning –What and when to plant; Matt Rose Commence before construction startsCommence before construction starts Ongoing for life of mineOngoing for life of mine Included in closure planningIncluded in closure planning Total of 6,615 new plantsTotal of 6,615 new plants

14. Revegetation program Highlighted areas are the domain based plans for the revegetation plan

15. Vegetation outcome OutcomeOutcome –Avoid loss of biodiversity through clearance of native vegetation. Significant environmental benefit (SEB) will be provided to increase biodiversity CriteriaCriteria –Periodic (at least annual) photographic evidence for specified photo monitoring sites will show no clearance of native vegetation. If vegetation is cleared, SEB will be provided in accordance with approved Native Vegetation Council guidelines

22. Visual amenity Minimising impacts of proposed structuresMinimising impacts of proposed structures –Placement & design of all structures is being developed to minimise impact on visual amenity –Placement in box cut, low lying ground –Infrastructure painted in neutral (green) tones –Revegetation planning, bunding –Night lighting focused down –Topsoil stockpiles <2.5m –Waste rock stockpiles <10m

23. Visual amenity The TSF is the most difficult structure to “hide”. Revegetation begins day 1The TSF is the most difficult structure to “hide”. Revegetation begins day 1 Measures to mitigate include:Measures to mitigate include: –Use of low lying ground to reduce height relative to undisturbed ground –TSF capping trials start Year 1

25. Visual amenity: Outcome OutcomeOutcome –improve visual impact & amenity of site CriteriaCriteria –photo monitoring points to indicate visual amenity of site improved relative to initial condition; monitoring points to be determined in consultation with the CCC
