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 agoLayers of volcanic ash soil settles on top of Pukewa.This slowy erodes until 1878 when an outcropping or quartz rock is spotted and starts mining for the next 70 odd years.

10

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.

11

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.

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.

VWT developing economic diversity for ongoing industry in Waihi

Independent authorities monitoring mining activities and environmental effects.

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….

22

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.

23

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.

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
