current economic climate
Current Economic Climate

Northern Territory’s economy is growing at 6-7% p.a.

Mining and Petroleum sectors are major economic drivers accounting for > 50% of NT growth.

Mining and Petroleum sectors comprise 26% of economy.

Australian commodity export earnings are expected to rise by 4 per cent to almost $145 billion this financial year.

6 new mines in last 18 months

4-5 more projects expected to

commence operations in next 12-18 months.

The 5 major existing mines have expansions

or extensions underway or proposed.

27 new Authorisations for exploration activities issued in the 2006\2007 financial year.

mining legislation
Mining Legislation

The Mining Management Act 2001 (MMA):

“ provide[s] for the regulation of mining activities, the management of mining sites and the protection of the safety and health of persons and the environment on mining sites, and for related purposes”

  • Co regulatory
  • Non-prescriptive
  • Continual improvement
  • Best practice
  • Whole of life mine planning
  • Risk assessment approach
  • Environmental consequences
  • Efficient cost effective manner
  • Cover all operational aspects
mining management plans
Mining Management Plans

As a basis, the Mining Management Act requires that the Mining

Management Plan includes:

  • A description of the mining activities to be carried out
  • Safety, health and environmental issues relevant to the mining activities
  • Plan and costing of closure activities

authorisations and evaluations
Authorisations and Evaluations

The Authorisations Team of the Minerals and Energy Group is the initial coordination point for guiding the Northern Territory’s mining operators in:

  • adopting recognised best practice
  • due diligence environmental management
  • workplace safety
  • occupational health
  • radiation safety
authorisations and evaluations1
Authorisations and Evaluations
  • The Evaluations Team’s work includes:
  • development of monitoring programs
  • provision of technical advice to support regulation
  • evaluation of monitoring of aspects of the environmental performance of mine sites in the NT under the Mining Management Act
environmental monitoring unit
Environmental Monitoring Unit

The Environmental Monitoring Unit is an on the ground unit that physically samples water from selected mine sites in the Northern Territory. 

  • The analysis of this data enables:
  • monitoring of mine site environmental performance
  • verification of the mining company supplied environmental data
avoiding legacy issues
Avoiding Legacy Issues
  • The Northern Territory Government is supportive of development projects that result in net material benefit for the community.
  • However the protection of the communities interest and the prevention of environmental harm, particularly in the event of project failure, remain a high priority.
  • One method available to the Government to protect the community interest should a mining project fail to fulfill its obligations is to hold a financial guarantee or security.
