1.0 INTRODUCTION
1.1 BACKGROUND
GWR Group Limited (GWR) own the Wiluna West Project which comprises eight iron ore deposits
over the two Banded Iron Formation (BIF) ridges (Ridges B and C as classified by GWR). Gold
deposits are known to occur in the swales between the BIF ridges and there are numerous Gold
Deposits that have been identified (13 in resource category).
Due to known occurrences of both minerals within the tenement package and depending on which
commodity was being put forward the Project has been referred to as both the Wiluna West Gold
Project (WWGP) and the Wiluna West Iron Ore Project (WWIOP).
There is a large iron ore resource (130Mt @ 60% Fe) with an associated reserve of 69.2Mt @
60.3% Fe and there has been extensive work completed over the last 10 years in developing the
WWIOP with various studies performed with two distinct options:
• Stage 1 – 1 -2 Mtpa operation looking at high grade deposits with low set up costs, utilizing a
mobile crushing and screening plant and road transport to either establish rail platforms or direct
to the Geraldton or Esperance ports.
• Stage 2 – 5-7 Mtpa operation looking at 10 Year mine Life and full reserve extraction, fixed
infrastructure on site but very dependent on major upgrade of rail and port facilities (Oakajee).
GWR has approval for:
• a 10 Mtpa development involving mining of the Bowerbird, C3 and C4 iron ore deposits (Reg
ID 55179); and
• a 1.5Mtpa development of the C4 deposits high grade iron ore (referred to as Stage 1) which
includes a 18.6 km haul road, a crushing /screening plant and associated infrastructure (Reg
ID 86015)
• the construction of a crushing/screening plant (W6444/2020/1).
Construction works of the crushing/screening were completed in December 2020 with
commissioning being completed in January 2021. GWR intend on operating the crushing/screening
plant under a Part V operating licence.
1.2 OBJECTIVE
As part of the C4 (Stage 1) iron ore deposit development, GWR intends to operate the following
prescribed premises:
• Category 5 - Processing or beneficiation of metallic or non-metallic ore (Modular crushing and
screening plant)
This document has been prepared to support the Licence application. Subject to approval, the
expected commencement date is scheduled for Q1 2021.
1.3 LOCATION
The Project is located approximately 700 kilometres northeast of Perth and 40 kilometres
southwest of Wiluna in the north-eastern Goldfields of Western Australia (Figure 1).
1.4 OWNERSHIP & LAND TENURE
The Project is located within M53/1087 which is 100% owned by GWR Group Limited (Table 1,

5.2 PRESCRIBED PREMISES
As part of the C4 development, GWR intends to operate the following prescribed premises:
• Mobile crushing and screening plant (Category 5) – 1.5 Mtpa (maximum).
The prescribed premises boundary and discharge points are shown in Figure 3.
5.3 KEY INFRASTRUCTURE AND EQUIPMENT
The key infrastructure and equipment is summarised in Table 3, with further detail specific to
the plant provided in the following sections.
GWR has constructed a stormwater catchment trench at the western end of the
crusher/stockpile area which slopes down towards. This will prevent potentially contaminated
stormwater from the plant/ROM area flowing into the surrounds.
After a rain event the stormwater will be pumped out and transported to the turkey’s nest.
GWR will ensure a pump with sufficient pumping capacity is maintained to ensure the trench
does not overflow.
Table 3: Key Equipment and Infrastructure to be installed
Category Equipment and Infrastructure to be installed
5 Crushing/Screening Plant
A mobile crushing and screening plant to provide two-stage crushing and screening
and a combination of diesel/electric powered modular mounted crushers, screens
and portable conveyors.
5.4 CRUSHING AND SCREENING PLANT
The plant will process the ore at rate of just under 1Mtpa (dry tonnes) (maximum 1.5 Mtpa).
Ore will be hauled to the ROM via a 1 km two-way haul-road from the open pit by the mining
fleet and stockpiles as directed.
All ore will be transported from the pit to various ROM stockpiles which may demarcate
different ROM grades and ore characteristics (e.g. high grade/low grade). The ROM will be
under the control of the ROM loader operator and traffic management will ensure positive
communication prior to entry. Ore will be processed through a mobile crushing and screening
circuit to produce two distinct ore products, Coarse Ore (Lump) and Fines stockpiles, with a
process flowsheet shown in Figure 6. Based on information available for stage 1 the crushing
and screening process is deemed fit for purpose.
The product will be stacked in separate stockpiles (Lump and Fines) and selectively removed
offsite via road trains to Geraldton.
The ROM stockpiles will have a total capacity of approximately 150,000 tonnes of ore and are
anticipated to be relatively dry. Dust suppression at the ROM will be achieved via the
installation of water sprays and the mobile water truck with expect moisture of between 5-8%
to minimise dust generation. Additional stockpile capacity of 50,000 tonnes will be in the DSO
products stockpiles to the west of the plant. Water sprays will be installed around the product
area to minimise dust generation.
Ore processing will consist of crushing and screening of the ore through a modular constructed
two-stage crushing and screening plant to produce lump and fines using an electric powered
modular mounted crushers, screens and portable conveyors. The plant will produce two
products: a lump product which is between 31.5mm and 6.3 mm product and a fine product (-
6.3 mm).
16GWR Group Limited Part V Licence Supporting Document
The ore will be fed into the hopper of the primary crusher using a front-end loader. The crushed
material from the primary crusher will then fed directly to a screen, set for a 32mm split size.
The undersize material will report to the secondary screen while the oversize material will
report to the secondary crusher. The undersize material from the secondary screens will report
to the fine’s product stockpile and the oversize material will report to the lump product
stockpiles.
Key design features of the plant design include plant operation is based on a single 12-hour
shift, 7 days per week roster. There is ample capacity in the circuit to increase production to a
24-hour, 7 day a week basis.
The ROM pad will cover an area (100m x 200m) with a 6 m high steel retaining wall located at
the northern end of the ROM pad. This will allow the ore bin apron feeder module to abut
against a 40 m long, 15 m wide ramp inclined at 10% grade to be feed by frontend loader.
Two stacker conveyors will transfer ore from the crushing and screening plant onto the Fines
and Lump stockpiles in one direction. The stacker conveyors will operate a 600mm wide belt
which will be equipped with dust suppression sprays.
Front end loaders will be fitted with bucket load cells to control loading operations for main
road compliance. An additional weigh bridge is located at the Rosslyn office area for secondary
and spot checks (outside of the Project area).
Table 5 summarises the crushing/screening plant design and operation requirements.

5.5 DIESEL & HYDROCARBON STORAGE
All hydrocarbons and chemicals will be located within bunded areas or on drip trays to contain
any potential spills. Bulk fuel storage will be within a self-contained, double-skinned storage
tank. They will be two Diesel Storage facilities onsite, one located near the power pack for the
Crushing and Screening facilities and the second for the mobile equipment for mining.
18GWR Group Limited Part V Licence Supporting Document
Waste oil will be stored in a tank and removed from site for recycling by a licensed collection
service. Oil filters and hydrocarbon-contaminated rags will be collected in approved
receptacles and removed from site to an appropriate facility at Rosslyn Hill.
Two self-bunded diesel storage facilities are to be installed at the C4 site. One of the diesel
storage facilities will be located adjacent to the power-pack for the crushing and screen plant.
The other 110kl storage tank will be location near the go-bay to facilitate the mining fleet and
miscellaneous mine vehicles requirements.
Self-bunded day tanks will be installed to provide fuel to stand-alone diesel generators (e.g.
producing water bores) at their respective locations where required.
All chemical and reagents classed as dangerous goods will be stored in accordance with the
requirements of the Dangerous Goods Safety Act 2004 and the Dangerous Goods Safety
(Storage and Handling of Non-explosives) Regulations 2007. Spill kits will be made available
for use to contain hydrocarbon spills.

7 ATTACHMENT 6A – EMISSIONS, DISCHARGES AND WASTE
7.1 POTENTIAL EMISSIONS
Potential emissions arising from the operation of the prescribed premises are:
• noise;
• dust; and
• contaminated stormwater resulting from plant/ore stockpile area to the surrounds.
The management measures and controls to be implemented are summarised in the risk
assessment presented in Table 7.
7.2 RISK ASSESSMENT AND MANAGEMENT SUMMARY
A summary of the potential environmental risks relevant to the Licence application and the
associated environmental management measures to be implemented to reduce these risks to
an acceptable level, are summarised in Table 7.
Based on GWR’s assessment of the Project siting (Attachment 7), it is considered that
vegetation, fauna, soil and groundwater are the only receptors. The closest residence dwelling
(pastoralist) is >20km away and the closest town is Wiluna (approximately 25 km away) from
the prescribed premises.
The residual risk assessment ratings are consistent with the risk assessment matrix used by
DWER as shown in (Table 8).

8.3 CLIMATE
The Project area is located within the Murchison region which exhibits an arid climate
characterised by hot dry summers and mild dry winters (CALM, 2002).
The nearest official meteorological station is located at Wiluna, approximately 40 km
northeast of the project area (Wiluna Station 013012). Recordings of the local climatic
conditions commenced at Wiluna in 1898 (Bureau of Meteorology, 2020). Relevant
temperature, rainfall, wind, evaporation and humidity data for Wiluna are summarised
below.
Mean annual maximum temperature is 29.2ºC and mean annual minimum 14.3ºC. Daily
maxima above 35ºC are usual from December to February. Diurnal temperature variations
are commonly high throughout the year.
The area is semi-arid and has an average annual rainfall of 260.4 mm. Most of the rain falls
from January to March but the amount varies greatly both seasonally and annually. The
highest daily rainfall recorded is 124 mm in February 1995.
The average wind speeds at Wiluna vary throughout the year from 8.1–12.9 km/h in the
morning to 8.5-13.2 km/h in the afternoon.
Evaporation is high, particularly in the summer months (December to February inclusive)
and the average mean daily evaporation rate is 6.6 mm (annual calculated rate is 2,409
mm).
Humidity levels vary considerably both daily and yearly. The mean monthly 9.00 am relative
humidity varies from a low of 30% in November and December to a high of 65% in July.
The mean monthly 3.00 pm relative humidity varies from a low of 19% in October, November
and December to a high of 42% in June.
8.4 REGIONAL SETTING
8.4.1 IBRA Region
The Interim Biogeographic Regionalisation for Australia (IBRA) divides the Australian
continent into 89 bioregions and 419 subregions (DAWE, 2020a). The proposed clearing
area is located within the Murchison bioregion and the Eastern Murchison (MUR1)
subregion of the IBRA (Thackway and Cresswell, 1995).
The East Murchison subregion lies on the Yilgarn Craton’s “Eastern Goldfields” and
“Southern Cross” Terrains.
The East Murchison bioregion is characterised by Mulga Woodlands often rich in
ephemerals, hummock grasslands, saltbush shrublands and Halosarcia shrubland (Cowan
2001). The area is characterised by:
• internal drainage;
• extensive areas of elevated red desert sandplains with minimal dune development;
34GWR Group Limited Part V Licence Supporting Document
• salt lake systems that are associated with the occluded Palaeodrainage system; and
• broad plains of red-brown soils and breakaway complexes as well as red sandplains
(Cowan 2001).
8.4.2 Soil-Landscape Zone
The project is located within the Salinaland Plains soil-landscape zone of the Murchison
Province (Tille 2006).
This zone which encompasses 132,450 km2, comprises sandplains (with hardpan wash
plains and some mesas, stony plains and salt lakes) on granitic rocks (and some
greenstone) of the Yilgarn Craton and comprises red sandy earths, red deep sands, red
shallow loams and red loamy earths with some red-brown hardpan shallow loams; salt lake
soils and red shallow sandy duplexes.
8.4.3 Land Systems
The Wiluna-Meekatharra area, covering 25,000 square miles, has been mapped and
described in 48 land systems, based on recurring patterns of topography, soils and
vegetation (Mabbut et al., 1963).
The prescribed premise is located on five Land Systems listed below (Mabbut et al., 1963):
• Glengarry – Sandstone plateaux, summits and hillslopes supporting mainly dense
mulga and other acacia shrublands, spinifex, and numerous low shrubs.
• Yanganoo – Almost flat hardplan wash plains, with or without small wanderrie banks
and weak grooving; supporting mulga shrublands and wanderrie grasses on banks.
• Bullimore – Gently undulating sandplain with occasional linear dunes and stripped
surfaces supporting spinifex grasslands with mallees and acacia shrubs.
• Sherwood - Breakaways, kaolinised footslopes and extensive gently sloping plains
on granite supporting mulga shrublands and minor halophytic shrublands.
• Dural – Strongly undulating terrain on weathered mudstone and basalt supporting
open mulga shrublands with mallee and spinifex.
The plant area is located within the Glengary land system.
8.5 GEOLOGY
The Wiluna West project covers a 25 km strike length over the Joyners Find Greenstone
Belt, near the northern margin of the Yilgarn Craton. The Joyners Find Greenstone Belt is
a narrow (5 km to 10 km) north-south striking greenstone belt comprising low ridges of BIF
(in the central and eastern portion) intercalated with mafic and ultramafic schists with minor
chert and clastic sediment horizons. The Joyners Find Greenstone Belt strikes north and
dips steeply to the west. Folds developed during the D2 deformation event are observed in
the BIF ridges as tight to isoclinal folds oriented north-south with west dipping axial planes.
The BIF ridges are variably deformed and intensely folded.
Two regional dextral shear zones are recognised: the Joyner’s Find Shear Zone (JFSZ)
strikes to the north through the centre of the belt and is parallel to the lithological strike; and
the Brilliant Shear Zone (BSZ) which is oriented north-northwest.
There are three main Banded Iron Formation (BIF) units which form ridges within the project
area (Units A, B and C). High grade DSO hematite mineralisation occurs within units B and
C with grade occurrences of up to 69% Fe. Iron mineralisation occurs within BIFs
surrounded by inter-bedded mafic and ultramafic schist units. The two main ridges show
distinctive mineralisation styles with B ridge showing a much lower proportion of remnant
bedding and generally a significantly higher portion of haematite especially in the top 20 m.
Mineralisation of the B ridge is also much more continuous along strike occurring semi-
continuously for over 15 km. The mineralisation on the C ridge typically occurs in a series
