Newcrest mine rehabilitation - Environmental Services

COOE has undertaken extensive environmental monitoring and studies at several Newcrest mines.

Telfer Gold Mine

COOE (under the old name of Natural Resource Services) were initially commissioned to provide an environmental officer in 2004 to support the Environment Manager during the construction of Phase 2 and provide senior level technical support as required.  COOE continued to provide technical support until 2016, some work examples included:

  • Provide mine closure specialists team to design, supervise the construction, monitor and document the rehabilitating of waste rock dumps to Mesa Landforms, a pioneering technology at the time. This work was tested on WD10 and WD11 on small scale and on a full dump scale at WD13. A status Mesa landform demonstration trials was established on WD16. This program ran between 2005 and 2016.
  • Undertake mine closure monitoring including landform stability, erosion, vegetation establishment and succession, weeds and feral animals, soil moisture, soil chemistry and meteorological conditions.
  • Ecosystem Function Analysis methods were used to measure performance of the rehabilitation at WD13 in meeting the criteria of returning the site to that found in surrounding landscapes.
  • COOE provided environmental supervision on the 450 km optic fibre installation between Port Hedland and Telfer.
  • AMD assessment, physical and chemical characterisation of all waste rock dumps, old tailings storage facilities and heap leach sites.
  •  Review of AMD model
  • Rehabilitation monitoring for soil fertility indicators (cation exchange capacity, exchangeable cations and major nutrients) and indicators for the potential mobilisation of metals and metalloids (arsenic, cadmium, cobalt, copper, iron and manganese).
  • Stygofauna monitoring between 2004 and 2008.
  • Arsenic mobilisation in soil and vegetation around the mine site.
  • Environmental Audits
  • Numerous environmental investigations on request.

Port Hedland Loading Facilities

COOE was commissioned to undertake an bi-annual marine monitoring program to meet licence conditions. This consisted of:

  • Undertaking baseline surveys for marine impacts at the Port Hedland concentrate loading facility.
  • Identifying environmental indicators for comparative purposes.
  • Outlining a monitoring program that will allow Newcrest Mining to demonstrate to its stakeholders that its environmental management practices at the Port Hedland concentrate loading operations are working as intended.
  • Sampling and analysing for metals in marine sediment and organisms at Berth 1 in Port Hedland and reporting on the accumulation of metals that may be associated to the loading activities of Telfer concentrate in Port Headland.


COOE was commissioned to:

  • Evaluate site AMD and status of closure activities.
  • Undertake a PSI (Preliminary Site contamination Investigation)
  • Prepare site remediation and Mine Closure Plans


COOE provided environmental staff to support Newcrest in preparing their Environmental Permitting Applications including:

  • Support flora and fauna survey teams.
  • Researching options for managing surplus water from mine de-watering

Namosi (Fiji)

Newcrest commissioned COOE to help investigate the potential of making bio-fuel in Fiji using natural and available resources.
