2.0 INTRODUCTION

2.1 Project Background

ANI is proposing to redevelop the CNO consisting of the Cosmos Pit, underground (UG) mining operations and Ore

Processing Facility (OPF) (the Project), located approximately 40km north of the Leinster township (Figure 1).

Jubilee Mines NL operated the Project from October 1999 to 2007 developing the Cosmos open pit and UG

operations. Xstrata (a subsidiary of Glencore) purchased the Project in 2007 continuing operation and then placed it

on Care and Maintenance in February 2012 due to the exhaustion of the Prospero ore body. ANI purchased the

Project in September 2015 with the aim to recommence mining operations.

ANI obtained approval to construct two additional water management ponds (WMP08 and WMP09) to support

dewatering of the Cosmos open pit and UG workings. The water management ponds were completed in November

and December 2018. Dewatering of the open pit commenced in November 2017 and has progressed to the UG

workings. Refurbishment of the decline commenced in December 2018 and surface earthworks are planned to

commence January 2020.

2.2 Scope of Application

To support the refurbishment of the decline and surface earthworks of the Project, screening and crushing is

required to produce suitable sized material for UG road base and surface hardstand areas. The current license

requires an amendment in order to undertake crushing and screening of the proposed 70,000t per annual period

under the EP Act.

2.3 Estimated Cost of Works

The cost of works is estimated at AUD $250,000.00.

3.0 DESCRIPTION OF THE ENVIRONMENT

3.1 Climate

The Project is located within the Murchison bioregion, classified as semi-arid with hot, dry summers and cool to mild

winters. The nearest Bureau of Metrology (BoM) weather station is located at Leinster (Leinster Aero Station

Number 012314). The mean annual temperature is 28.2°C and the mean annual minimum temperature is 14.7°C.

Daily maxima greater than 30°C are common between October and March (Bureau of Metrology, 2019).

The mean annual rainfall is 264.5mm with 80% occurring between December and July. Rainfalls >1mm occurs on

average 32.4 days per year (Bureau of Metrology, 2019).

Dominant wind direction is easterly in the mornings increasing to northerlies in winter. The average wind speeds

vary from 16.0 to 21.4km/hr in the morning and 15.6 to 19.4km/hr in the afternoon. Annual evaporation rates are

between 3000 to 3200mm, exceeding the annual rainfall (Bureau of Metrology, 2019).

Graph 1 Leinster Aerodrome Weather Station Climate Averages

3.2 Landforms and Soils

3.2.1 Land Systems

The prescribed premises boundary is located within the Salinaland Plains Zone described as:

Sandplains (with hardpan wash plains and some mesas, stony plains and salt lakes) on granitic rocks of the

Yilgarn Craton with Red sandy earths, Red deep sands, Red shallow loams (sometimes with hardpans) and

Red loamy earths.

Soil landscape mapping identifies several land systems intersecting the prescribed premises boundary (Table 3).



Table 3: Prescribed Premises Land Systems

Land System Description

Jundee System Hardpan plains with variable gravelly mantles and minor sandy banks supporting weakly groved mulga shrublands.

Laverton System Greenstone hills and ridges with acacia shrublands.

Violet System Gently undulating gravelly plains on greenstone, laterite and hardpan, with low stony rises and minor saline plains; supporting groved mulga and bowgada shrublands and occasionally chenopod shrublands.

Duketon System Stony wash plains and sandy banks supporting mulga shrublands and wanderrie grasses.

Ararak System Broad plains with mantles of ironstone gravel supporting mulga shrublands with wanderrie grasses.

Mileura System Saline and non-saline calcreted river plains with flood plains and calcrete platforms supporting variable tall shrublands, mixed halophytic shrublands and shrubby grasslands.

Carnegie System Salt lakes with fringing saline alluvial plains, kopi dunes and sandy banks, supporting halophytic shrublands and acacia tall shrublands.

3.2.2 Soils

Soils typically consist of shallow earthy loam overlying red-brown hardpan; shallow stony loams on hills and red

earthy sands on plains (Beard, 1990). Soil mapping shows majority of the prescribed premises boundary within the

red shallow loam soil type (Table 4 and Figure 2).

Figure 2: Soil Landscape Units



3.3 Geology

The prescribed premises boundary lies within the Agnew-Wiluna portion of the Norseman-Wiluna Greenstone belt.

The belt is attenuated and characterized by major wrench faults traceable over tens of kilometres with at least two

phases of complex folding and generally steep dips. The greenstones are dominated by a sequence of NNW striking

tholeiitic pillow basalts intercalated with a package of felsic to intermediate volcanoclastic-metasedimentary rocks

and ultramafic spinifex textured and cumulate komatiite units.

The local area comprises a package of felsic to intermediate volcanoclastic rocks, with minor interflow sedimentary

rocks and the polymictic Jones Creek Conglomerates. These units inter-connect with a sequence of tholeiitic basalts

(Mt Goode Basalt) and two ultramafic komatiite flows, the Western and Central Ultramafic (Mt Goode Dunite) (EGI,

2018).

3.4 Hydrology and Hydrogeology

3.4.1 Surface Water

The surface water catchment is 42.1km2 with the upper catchment being hilly and rugged with elevations ranging

between 500 and 520mAHD. The downstream catchment, where the Project is situated, comprises an open, flat

valley with elevations ranging between 470 and 490mAHD. Numerous smaller tributaries flow into a main north to

south drainage line known as Freshwater Creek and towards Lake Miranda.

Minor drainage lines are defined and well vegetated in the steeper hill slopes to the west and north of the Project,

becoming less defined towards the south. A series of small drainage lines trend east and south-east from rocky hills

to the west, joining Freshwater Creek, located east of the WMP’s and TSF. Freshwater Creek becomes less distinct

towards the south where surface water floods across a wider plain. Surface runoff flows within these ephemeral

drainage lines following heavy rainfall associated with thunderstorms or cyclonic activity.

The Project is not located within a Surface Water Proclamation Area.

3.4.2 Groundwater

Mine dewatering is managed via a series of water storage receptors comprising dis-used pits and Water

Management Ponds (WMPs). The hydrogeological conditions beneath the WMPs comprise low permeability alluvial

deposits and saprolitic clays forming the facilities natural base. Weathering depths are known to be highly variable

across the Project area, the minimum saprolite thickness is approximately 20m. Secondary ferricrete development is

also extensive underneath the ponds, providing a barrier to vertical groundwater flows.

Regional palaeochannels transport large quantities of hypersaline water via underground streams running north to

south. The hydrogeology is characterised by fractured rock aquifers holding variable pockets of brackish to

hypersaline groundwater, and zones of near surface high permeability where coarser aggregates and channel sands

alternate between clay and felsic layers (Landloch, 2010).

3.5 Flora and Vegetation

The project is situated within the Murchison (MUR) Bioregion within the Eastern Murchison (MUR1) subregion

totalling +7.8 million hectares (CALM, 2002). This subregion is characterised by its internal drainage, and extensive

areas of elevated red desert sandplains with minimal dune development. Salt lake systems associated with the

occluded palaeodrainage system, broad plains of red-brown soils and breakaway complexes as well as red

sandplains. Vegetation is dominated by Mulga Woodlands often rich in ephemerals; hummock grasslands, saltbush

shrublands and Halosarcia shrublands (CALM, 2002). Several flora surveys have been undertaken recording 89

species from 40 genera and 19 families (PEK Enviro, 2017).

3.5.1 Conservation Significant Flora

There are six conservation significant flora species that potentially may occur in the regional area (Table 5). Flora

surveys undertaken have not recorded these species within the prescribed premises boundary.

3.5.2 Conservation Significant Ecological Communities

No Threatened Ecological Community (TEC) pursuant to Commonwealth or State legislation is located within the

prescribed premises boundary. None of the vegetation communities within the survey area were found to have

National Environmental Significance as defined by the Environment Protection and Biodiversity Conservation Act

1999 (EPBC Act 1999).

The Project is situated within the buffer zone of a Priority Ecological Community (PEC); the ‘Violet Range

(Perseverance Greenstone) vegetation complexes (banded ironstone formation - BIF).’ This Priority 1 PEC has a

known extent over 14,000 hectares. PEK (2017) identified that the four vegetation communities comprising this PEC

are unlikely to be found within the prescribed premises boundary, as the survey area is located on colluvial sheet

wash plains, sheet wash deposits and alluvial floodplains and is situated to the east of the Violet Range. In addition,

no areas of BIF have been mapped within the Project area.

3.5.3 Weeds

Several weeds have been recorded at the Project area:

Paddy melon (Citrillus lanatus)

Prickly paddy melon (Cucumis myriocarpus).

Ruby dock (Acestosa vesicaria)

Various thistles (Sonchus sp)

Rosetted Tobacco (Nicotiana rosulate)

Buffel Grass (Cenchrus ciliaris)

These species have mostly been recorded in disturbed or rehabilitated sites. Citrullus lanatus has been recorded

within an undisturbed area along a drainage line. These species are not declared weeds under the Biosecurity and

Agriculture Management Act 2007.

3.6 Terrestrial Fauna



Several terrestrial fauna surveys have been completed over the Project area. No conservation significant fauna or

habitat types have been recorded during these surveys. Desktop analysis lists several species that may occur within

the regional area (Table 6).

Table 6: Conservation Significant Fauna

3.6.1 Feral Animals

Several feral animals that have been declared a pest under the Biosecurity and Agriculture Management Act 2007

(BAM Act) have been recorded within the Project area and include:

Red Fox (Vulpes vulpes)

Rabbit (Oryctolagus cuniculus)

Feral Cat (Felis catus)

Feral Donkey (Equus asinus)

Feral Dog/ Dingo (Canis familiaris)



4.0 CRUSHING AND SCREENING

4.1 Description

Mobile Crushing and Screening is required to generate suitable aggregate to support the CNO operation. It is

estimated that 70,000t of crushed aggregate is required. A description of the proposal is provided in Table 7.

Table 7: Mobile and Crushing Plant Description

4.2 Inputs and Outputs

The inputs and outputs of the mobile and crushing plant are described in Table 8.

Table 8: Inputs and Outputs for Crushing and Screening

Input Quantity Output Quantity

Feed material 70,000t Crushed aggregate material (max 75mm)

70,000t

Power supply Diesel (tracked usage)

Raw water 5,040L per 12 hour operation

The mobile crushing and screening plant is expected to produce approximately 60,000t worth of material for the

construction phase of the CNO. An additional 10,000t has been included to account for delays and any possible

excess material requirements making the overall production application total 70,000t.

4.2.1 Power Supply

The mobile crushing and screening plant will be powered via a tracked supply of diesel with refuelling occurring

through service trucks. Any spills of hydrocarbons will be reported via the ANI Incident Notification System and

cleaned up using spill kits. Any remaining contaminated material will be excavated and taken to the bioremediation

facility for treatment.

4.2.2 Water Supply

Water requirements are expected to be ~5,040L per 12 hour shift. Water will be sourced from the raw water bore

located at Yakabindie Borefield and trucked via water carts to the plant. Groundwater licenses and an agreement

have been obtained by ANI (see Section 2.6.1).

4.3 Location

The mobile crushing and screening plant will be located within the prescribed premises license (Figure 3). The

proposed location will be prepared by striping vegetation and topsoil and stockpiling to a designated area. The area

will be built up using blasted rock material and flattened. Surface water infrastructure such as drainage lines,

culverts or bunds will be installed where required to prevent surface water flooding of the area, or divert and

contain any surface water from the area to a designated sump.



Figure 3: Proposed Location of Mobile Crushing and Screening Plant within Prescribed Premises Boundary



4.4 Mobile Crushing and Screening Plant

The mobile crushing and screening plant will consist of one plant with a jaw crusher capacity of approximately 500-

1000t per hour. The anticipated annualised output for the facility is 70,000t. It is anticipated this material will be

produced during the construction phase of the CNO.

Raw material feeding the plant will be sourced from the Underground Waste Rock Dump (UG WRD). Material will be

hauled to the location of the crusher and fed from a stockpile, or alternatively fed directly from the UG WRD.

Material will be fed by a vibrating grizzly feeder sizing the material. Material passed will be crushed via the jaw

crusher and screened to produce a variety of sized material. Appendix 2 provides the technical specifications of the

proposed plant (yet to be confirmed).

Dust emissions from the crusher and product conveyor will be mitigated through the utilisation of sprayers which are

capable of utilising 7L per minute.

4.5 Proposed Works Schedule

The schedule for the mobile crushing and screening plant is proposed to be undertaken in the below sequence:

Ground disturbance and stockpiling of topsoil and vegetation to designated area

Earthworks and site preparation using benign overburden material

Where required, installation of surface water drainage infrastructure

Mobilisation of the plant to site for commissioning of crushing and screening

Operation of the crushing and screening plant producing crushed aggregate material 70,000t per annual

period.



5.0 DEWATERING STANDPIPE

5.1 Description

A standpipe from the dewatering pipeline is required to be installed to provide suitable quantities of water for dust

suppression activities on roads and hardstand areas. The standpipe is proposed to be installed where adequate

water pressure can be obtained for optimal and ongoing use. A description of the standpipe is included in Table 9.

Table 9: Standpipe Description

Feature Description

Location The proposed standpipe will be located within the current prescribed premises boundary (Figure 3). There are two options for instalment with Option 1 being preferred.

Inputs and outputs Mine dewater, power supply

Outputs Mine dewater for dust suppression

Equipment Water Cart, standpipe, generator

Environmental emissions Surface water run-off

5.2 Inputs and Outputs

The inputs and outputs of the standpipe for dust suppression are described in Table 10.

Table 10: Inputs and Outputs for Dewatering Standpipe

Input Quantity Output Quantity

Mine dewater 1,796,115t Mine dewater for dust suppression

1,796,115t

Power supply Diesel (tracked usage)

The standpipe is expected to utilise up to 1,796,115t of the mine dewater per annual period. Maximum water

abstraction for underground mine dewatering is expected at 150L/s equating to 4,849,511t per annual period. There

will be no required change to the current premises production or design capacity being 3,000,000,000 tonnes per

annual period.

5.2.1 Power Supply

The standpipe can be powered via a tracked supply of diesel with refuelling occurring through service trucks. Any

spills of hydrocarbons will be reported via the ANI Incident Notification System and cleaned up using spill kits. Any

remaining contaminated material will be excavated and taken to the bioremediation facility for treatment.

5.2.2 Water Supply

Water requirements are expected to be 1,796,115t of the mine dewater per annual period. Water will be sourced

from the underground mine dewater pumped to surface.

5.3 Location

The standpipe will be installed on already disturbed land (Figure 4). The area will be built up using rock material and

flattened to a hardstand area. Surface water infrastructure such as drainage lines, culverts or bunds will be installed

where required to prevent surface water flooding of the area. Any surface water run-off from the standpipe when

utilised will be diverted and contained using a sump or similar.



Figure 4: Proposed standpipe locations



6.0 ENVIRONMENTAL MANAGEMENT

6.1 Surface Water

ANI will install surface water infrastructure where required to control and direct surface water flows to minimise

flooding and contact with work areas. This may include bunding, culverts, drainage lines or collection sumps. ANI will

also grade areas as required to ensure any contaminated stormwater or runoff from work activity areas is directed

to a designated collection area and treated accordingly if reused or disposed.

6.2 Groundwater

ANI will manage groundwater in accordance with the Groundwater Resource Management Plan (Groundwater

Resource Management, 2016). This will include the utilisation of the existing groundwater recovery bore network,

rotation of discharge points within the water management ponds and implementation of a trigger depth value of 6m

to identify any unacceptable impacts when action is required.

6.3 Chemicals and Hydrocarbons

Chemicals and hydrocarbons utilised during the CNO will be managed to ensure:

Storage of hydrocarbons and chemicals in accordance with AS 1940-2004

Utilisation of spill pallets and other containment facilities during maintenance works

Positioning of spill kits in areas where the potential of spills is likely to occur such as mechanical or

maintenance workshops

6.4 Biodiversity

ANI will protect conservation significant values by implementing the Ground Disturbance Permit system during

clearing operations. This will ensure identified high value conservation areas will be protected during clearing

operations through avoidance. ANI will also undertake annual vegetation health monitoring to determine the

effectiveness of ANI’s groundwater management plan.

6.5 Dust

Dust will be managed through suppression activities such as:

Dust suppression utilising water carts along roads (main roads and haulage routes) and on hardstand

areas

Utilisation of sprayers or sprinklers where required to minimise dust emissions

Enforce speed limits along roads to mitigate dust emissions.

6.6 Noise

The proposed location of crushing and screening is located at least 4.5km from the nearest homestead (Yakabindie

Station). The nearest regional town site is Leinster at 32km south of the prescribed premises boundary. Noise will be

managed in accordance with the Occupational Noise Management Standard AS/NZS 1269 and the Management of

Noise in Western Australian Mining Operations Guideline. Noise buffering distances of 1km will be implemented

from identified sensitive receptors. Accordingly, no impacts to human health or amenity at residential receptors are

anticipated as a result of noise.
