  5. Describe How and Why people Use a particular Environment For A Particular Activity • 20 million years ago volcano's burst through landscape, made of andesite rock. This continues on for 15 million years. Between 7 -20 Million years Earthquakes rupture land. Waihi is a geothermal zone. Geysers threw mineral rich boiling water into the air, pushing these up through cracks in volcanic rock. It looked much like Rotorua does today. 5 -2 Million years ago Layers of volcanic ash soil settles on top of Pukewa. This slowy erodes until 1878 when an outcropping or quartz rock is spotted and starts a gold rush for the next 70 odd years.

  6. Describe How and Why people Use a particular Environment For A Particular Activity • The Martha lode is found and has been created along a fault line with some very particular conditions existing that makes it a very lucrative ore body 1.5 km long and 30 metres wide. • Today from that discovery we continue to explore and find further ore bodies within a similar location.

  7. Explain the consequences of use of an environment on people and places • Social • Dust • Vibration • Nosie • Water • Biological – plants and water • Economic – jobs, royalties, wages, goods and services, donations, schools, Waihi Vision Trust Environmental – 175 kms of tunnels through out hill, open cast mine, underground mine, waste rock embankments created from paddocks, water treatment, riparian planting over 500,000 natives, wildlife, NZ dotterel, ducks, gulls, wetlands Cultural – Community Marae in area. Waihi a trading route between coasts and also Hauraki Maori.

  8. What is our economic performance? • We employ 400 staff and contractors • Another 400 people indirectly employed • On average we spend around $190M a year on goods, services, rates, taxes, royalties. • 32% is spent locally (within 30km of Waihi) • 29% is spent regionally (Bay of Plenty, Waikato, Coromandel) • 21% is spent in the rest of NZ • 18% is spent overseas • In the last five years: $239m in capital expenditure and $694m in operational expenditure • 82% of this money is spent in New Zealand • Since 2006 we have spent $264m on goods and services in and around Waihi, a town of 4,500 people • Since 1987 more than 2.5 million ounces of gold and 20 million ouncesof silver have been produced

  9. What is our social & community performance? • Donations, sponsorships, partnerships • Vision Waihi Trust & Waihi Community Vision • Gold Discovery Centre • Sport’n’Action sports hub • Creative Waihi • Waihi Heritage Vision • Social Development Group • Waihi Gold Education Trust • Dotterel Watch partnership with DoC • Beach Hop Warm Up Party • Over 50 community organisations, groups or clubs assisted in 2011 • Riparian planting – almost 500,000 native trees and shrubs 9

  10. Support for mining over time Independent poll carried out by Phoenix Research Ltd

  11. What do people in Waihi perceive to be the disadvantages of mining?

  12. What do people in Waihi perceive to be the benefits of mining?

  13. Sustainability of the environment for gold mining How does Newmont minimise impacts on the environment Resource Management Act following strict licensing conditions minimising environmental and social impacts. Comprehensive rehabilitation plans in place before mining begins. Ongoing environmental plantings and development throughout mining license. WVT developing economic diversity for ongoing industry in Waihi Independent authorities monitoring mining activities and environmental effects.

  14. Before: evidence required for a RMA application • Project description (mine design, mining method, geology, etc.) • Metallurgy • Air quality • Vibration • Receiving water quality / ecology • Noise • Geochemistry • Hydrogeology / settlement • Traffic • Economic impact • Property / community investment • Consultation summary….

  15. During: monitoring of operations and reporting • Real-time monitoring of vibration • Noise monitoring • Dust / air quality monitoring • Water levels • Water quality – bores around TSF; water in discharge and overflow ponds; water treatment plant quality; upstream and downstream monitoring • Bio-monitoring • Ground settlement and tilt • Complaints Reporting on all of the above to District and Regional Councils.

  16. After: rehabilitation and monitoring • Progressive environmental rehabilitation • Economic and social sustainability • Rehabilitation and capitalisation bonds: • Martha Pit Rehabilitation Bond: $26.2m (two separate bonds - jointly overseen by HDC and WRC). • Ministry of Energy and Resources Bond: $1.25m • Water rights bond with WRC: $2m • Conservation bond: $0.057m (for DoC land) • Capitalisation bond: $10.4m (formation of Martha trust) • Martha Trust: responsible for management of sites, rehabilitation, and monitoring in perpetuity.

  17. Resource Consents • Community Relations • NWG must appoint a Company Liaison Officer to receive complaints from the community

  18. Water Management System • Restrict generation of acid drainage • Control of tailings underdrainage • Collection of water from: • Open pit • Favona • Process plant • Tailings storage facility • Stormwater via Silt and Collection ponds • Treat water to level appropriate for discharge • Discharge to the Ohinemuri River

  19. River monitoring sites a) OC2 b) OH3/A c) OH5/B d) OH1/UPD e) OH6/DPD f) RU1/R2 OH3 – u/s of upper discharge OH5 d/s of upper discharge OC2 - Upstream of site Ruahorehore confluence OH1 u/s of lower discharge OH6 – d/s of lower discharge

  20. TSF management • Pond water level monitoring • Bird monitoring • Peak recorded number of birds taking sanctuary on any day = 900

  21. Vibration Monitoring System • Compliance Requirements • Monitoring specifications comply with the criteria set down in the Hauraki District Plan • A complete record of each blast is required, including all blast design details • Any complaints are documented

  22. Dust Monitoring Ambient air trigger limit = 45 µg/m³ Trigger limits are from the National Air Quality Guidelines and not a compliance limit. The Mining Licence limit = 100 µg/m³)

  23. Rehabilitation Plans for the Future • Martha Pit filled to create recreational lake and park • Estimate 27 years to fill with rain and natural groundwater inflows • Est. 6-7 years to fill if supplemented by Ohinemuri River flood flows • Tailings Storage Facilities • Wetlands and native plantings • Grazing
