OTHER SIGNIFICANT EMISSIONS
IGO completes annual National Pollutant Inventory (NPI)
reporting in accord with Australian law. The NPI is used
to track pollution across Australia, and to ensure that the
community has access to information about the emission
and transfer of toxic substances which may affect them
locally. The NPI contains data on 93 substances that have
been identified as important due to their possible effect
on human health and the environment.
In FY2015, IGO key NPI reportable pollutants were

MINE CLOSURE PLANNING
Closure planning is a complex process. The planning
horizon is typically measured in decades. Planning for
mine closure has social, economic and environmental
parameters that generally change over the life of a mine.
The difficulties associated with mine closure are often
the product of poor initial planning. Consequently closure
planning is a matter for consideration during all stages
of operation, and particularly, during a project’s feasibility
phase. Mindful of this, and in conformance with Western
Australian law, IGO has Mine Closure Plans’ for both its
Jaguar and Long Operations. These were developed in
accordance with the ‘Guidelines for Preparing Mine Closure
nt of
Western Australia’s Department of Mines and Petroleum
(DMP). Similarly, the Tropicana Operations JV has submitted
a conceptual mine closure and rehabilitation strategy.
In May 2015, the DMP issued an updated set of guidelines
n
response, IGO will commence a review of its mine closure
plans in FY2016. Further, given IGO’s intention to grow
its business, and given the likelihood that it may expand
into new jurisdictions, IGO will also work to ensure closure
plans conform with the ICMM Planning for Integrated Mine
Closure: Toolkit ).
The potential impacts of closure are an ongoing
consideration in IGO’s engagement with governments
and local communities. Potential impacts of closure are
also considered in regard to our support of community
development initiatives and local business.
Provisions are made for the estimated cost of
rehabilitation, decommissioning and restoration relating to
areas disturbed during the mine’s operation.
Mine
Estimated Cost
of Closure
Tropicana JV $60,069,861
Long Operation $1,081,700
Jaguar Operation $10,295,440
At present IGO’s mine closure plans are not subject to
independent audits nor are they readily publicly available.
Once complete, IGO will arrange for them to be audited
and made publicly available.
As a social good, IGO, like many other mining
companies, pays a Mining Rehabilitation Fund
(MRF) Levy to the Government of Western Australia
t is the State’s
position that money in the fund will be available to
rehabilitate abandoned mines across Western Australia.
Interest earned on fund contributions will be available
to spend on rehabilitating legacy abandoned mines. In
FY2015, IGO’s levy payments totalled $121,503.72
