The Quarry is to be located adjacent to the Mardie Access Road and lies approximately 1 km
north-west of the Mardie Access Road - Northwest Coastal Highway intersection. The quarry
covers an area of approximately 15.5 hectares (ha) and will be mined to a depth of up to 20
metres (m). Figure 2 below shows the location of the proposed quarry in relation to surrounding
landmarks. Up to 2 Mm3 of material will be extracted during the first four years of construction
and operation. The quarry may then operate for the life of the Optimised Project at a reduced
rate with the purpose of providing rock material for the maintenance of embankments and roads.
Extraction of raw material involves blasting when required. All blasting will be undertaken by
contractors and no explosive materials will be stored on site. Excavation and blasting activities
are not considered within the scope of this works approval.
Mined material will be moved via front end loader to a mobile crushing and screening plant (the
subject of this works approval) located adjacent to the quarry pit where it will be processed and
sized dependant on the end use. Crushed material will be sorted and stacked adjacent to the
crushing and screening plant. As required, the processed material will be loaded onto haul
trucks and transported via the Mardie Access Road to its intended destination.
Product sourced from the quarry will be for use within the Mardi Project only and there are no
plans to export the product off site. Operations at the quarry are intended to be 24 hours a day
7 days a week on a ‘when required’ basis. It is expected that approximately 1.7 million tonnes
of material will be processed through the crushing and screening plant per year.
Site construction will be undertaken under the framework of a dedicated Construction
Environmental Management Plan (CEMP). The CEMP will provide an overview of
environmental controls that will be implemented for all identified environmental impacts. Based
on this overview, the Applicant has identified emission risks from construction and operation of
the crushing and screening plant and will implement a range of measures to reduce risk of
emissions.
Hydrocarbon stored on site will be limited to a 50-60kL self-bunded tank, the location shown
below in Figure 3.
Construction and operation of the crushing and screening plant at the quarry will require the
following supporting infrastructure:
• Access road from Mardie Access Road;
• Laydown;
• Office;
• Vehicle parking;
• Fuel storage 50-60kL self-bunded tank;
• Small workshop; and
• Material stockpiles.
Machinery and infrastructure associated with the proposed crushing and screening activities
will consist of:
• Mobile rock-breaker;
• 300 TPH feed grizzly;
• Finlay J-1480 screen;
• Finlay C-1550 direct feed x2;
• Finlay 893 HD screen; and
• Conveyor.
