1. INTRODUCTION

BACKGROUND

Doral Mineral Sands Pty Ltd (Doral) propose to mine the Yalyalup Mineral Sands Deposit, located

approximately 11km east southeast of Busselton (Figure 1) on the Swan Coastal Plain (i.e. the Site). The

Yalyalup deposit has an approximate disturbance footprint of ~372.67ha within an 894.17ha

Development Envelope and encompasses an area Doral have been granted Retention Licence R70/0052,

which covers an area of approximately 2,290ha. (Figure 2). The deposit is also located ~4km southeast

of the Wonnerup Mine Site (Cristal Mining Australia), ~2.5km northwest of the Tutunup Mine site (Iluka

Resources Ltd) and ~6km northeast of the Yoongarillup Mine Site (Doral).

The deposit occurs in an area depicted on an Acid Sulfate Soil (ASS) risk map as Class II ‘moderate to low

risk of ASS occurring within 3m of natural soil surface’. Ore from the deposit will be mined progressively

via a series of open-cut pits using dry mining techniques to an expected maximum depth of ~12mbgl.

Dewatering of groundwater inflows into the mine pits will likely be required in some areas to enable dry

mining to occur.

As mining will involve the disturbance of greater than 100m3 of soil or sediment from below the natural

water table in a Class II ASS risk area and also the lowering of the water table in a Class II risk area, Doral

have undertaken a targeted ASS investigation in accordance with the Department of Water and

Environmental Regulation (DWER) guideline Investigation and identification of acid sulfate soils and acidic

landscapes (DER, 2015a) to assist in determining the potential presence and distribution of ASS, and if

present provide details of proposed management measures.

OBJECTIVES

The objective of the ASS investigation and management plan (ASSMP) was to:

• Conduct soil sampling to identify the presence or the absence of ASS in areas likely to be

disturbed;

• Assess the net acidity (comprising both existing and potential acidity) of soil at locations where

mining is likely to result in disturbance below the natural groundwater table;

• Assess the baseline quality of groundwater (from existing landowner and DWER bores) that will

require dewatering;

• Provide appropriate management measures, where required.

SCOPE OF WORK

The scope of works for the ASS investigation was developed based on Doral’s resource definition drilling

program which comprised 31 exploration drill holes to approximately 2m below the maximum

anticipated depth of disturbance. The scope of work included the following:

• Collection and logging of soil samples at 1m intervals from 31 targeted locations (i.e. deepest

areas of excavation) to approximately 2m below the proposed maximum depth of excavation;

• Field testing of all soil samples for pHF and pHFOX;

• Laboratory analysis using the Chromium Reducible Sulfur (CRS) method for samples with a pHFOX

less than three;

2

• Assessment of baseline groundwater quality from available existing groundwater monitoring

wells;

• Preparation of an ASS investigation and management plan.

2. EXISITNG ENVIRONMENT

LOCATION AND LANDUSE

The Yalyalup deposit has a total disturbance area of approximately 372.67ha within an 894.17ha

Development Envelope and is located within the City of Busselton ~11km east southeast of Busselton,

WA (Figure 1). The Site currently encompasses an area Doral have been granted Retention Licence

R70/0052, which covers an area of approximately 2,290ha. The ASS investigation was undertaken in areas

south of Princefield Road, North of Yalyalup Road and between the Wonnerup South Road (west end)

and Ludlow Hithergreen Road (eastern end) (Figure 2).

The Site is located in the Southern Perth Basin, approximately midway between the current coastline and

the base of the Whicher Scarp. The Southern Perth Basin sediments are predominately Permian to

Cretaceous aged with a thin cover of Pleistocene and Recent sediments.

All land comprising the Site is zoned ‘agricultural’ in accordance with the City of Busselton’s Local Planning

Scheme (LPS) No. 21. The deposit has been extensively cleared in the past 50-100 years for agricultural

purposes. The dominant land use at present is cattle grazing and hay production. Land has also been used

for dairy production in recent years with minor irrigation of pasture with untreated effluent water

(sourced from dairy within Lot 843). Localised excavation of farm dams has exposed minor areas of the

underlying sediments to the atmosphere.

Remnant vegetation within the Site bounds is restricted mainly to road reserves and creek lines, with

other scattered clusters of native vegetation occurring in paddocks. Several landholders have planted

tree belts that include pine trees and other non-endemic eucalyptus species.

CLIMATE

The Busselton area experiences a Mediterranean climate with warm to hot dry summers, and mild wet

winters. High pressure cells dominate climatic patterns during summer and the passage of cold fronts

and associated low pressure cells dominate during winter. Strong sea breezes occur from late November

to early March. The annual rainfall generally falls within the 800mm and 1000mm range, peaking in June

and July, as shown in Chart 1. In summer the average maximum temperature is 28°C with an average

minimum temperature of 12°C. In winter the average maximum temperature is 16°C with an average

minimum temperature of 5°C (Bureau of Meteorology, 2017).

GEOLOGY

The Southern Perth Basin in Western Australia comprises of Permian to Recent sediments. Erosion of

pre-Cambrian igneous rocks (Yilgarn Craton in the East, Leeuwin Naturaliste Block in the West) has

contributed to the deposition of sediments bearing heavy minerals in the Yalyalup Road area. Heavy

minerals have accumulated into economically viable strandlines and dunal systems due to the action of

wind and waves on coastal shoreline areas.

The well-defined strandlines in the Yalyalup Deposit are largely contained within the Pleistocene aged

Yoganup Formation. These strandlines generally run parallel to the present-day coastline of Geographe

Bay. Strandlines typically form on wavecut platforms at recognised elevations over wide areas. On the

down slope areas of these platforms, lower grade heavy mineral accumulation can also occur within the

Yoganup formation. The Cretaceous aged Leederville Formation usually forms the ‘basement’ below the

wave cut platform areas.

Dunal heavy mineral deposits are typically present above and inland from the main strandline locations.

Aeolian deposits are found in various sections on top of the Guildford Formation and/or the Leederville

basement within the two Yalyalup tenements. These are shown in Figure 3 and annotated as Ed4

(Degraded surface of Eolian origin, Bassendean Dunes). Dunal sands are often heavily altered and feature

elevated levels of leucoxene and zircon.

Groundwater movements have allowed the formation of iron rich cementation horizons in some of the

deposit. The cementation presents as pisolitic to massive iron oxide cemented sandstone. Within this

cemented layer and above it, the heavy mineral assemblage is enriched in the alteration products of

ilmenite (leucoxene and altered ilmenite). In this upper zone the ilmenite chemistry is often enriched in

Al2O3. Below the cemented layer, the heavy mineral assemblage is more typical of the Yoganup Formation

with a greater proportion of unaltered ilmenite with low Al2O3 content.

HYDROGEOLOGY

Groundwater is present in the area within a multi-layered aquifer system. The superficial deposits contain

an unconfined aquifer with saturated thicknesses of generally less than 10m, whereas the Leederville and

Yarragadee Formations contain multiple regional-scale confined and semi-confined aquifers.

Superficial Aquifer

Unconfined groundwater in the superficial formations occurs at approximately 1-3mBGL, with a

consequent saturated thickness of approximately 10-14 m, based on water levels obtained from local

bores by Doral during initial groundwater monitoring in May-June 2017 and ongoing monitoring. Seasonal

variation in the water table, derived from existing DWER hydrographs in the area, is in the range of

approximately 1-2m. A water table based on Doral measurements for the Superficial Aquifer is shown on

Figure 4, although this is a preliminary estimate, pending re-surveying of these bores. Given the age and

usage history of many of these private bores, their construction, current condition and the reliability of

their elevation information may render them insufficient for monitoring purposes.

Regional groundwater flow is expected to occur to the northwest in the Site vicinity, as shown in Figure

4, which also indicates a hydraulic gradient within the superficial aquifer of approximately 0.0037

(HydroSolutions, 2017). The ultimate discharge point is likely to be Geographe Bay and the Vasse –

Wonnerup RAMSAR wetland, ~4.6km to the northwest. Recharge occurs by rainfall, although a large

proportion of this infiltration is likely to be lost due to evapotranspiration due to the shallow water table.

The superficial formations are variable across the region and hydraulic conductivities are site-specific.

However, in general, hydraulic conductivities have been estimated to be in the range of 0.5-50m/d

(Davidson, 1995) (Hirschberg, 1989), with an average of 15m/d, partially dependent on the percentage

sand content. HydroSolutions (2014) pumping tests within the Bassendean Sand and sandy facies of the

Guildford Formation in the Bunbury area indicated transmissivities of 483-731 m2/d and corresponding

hydraulic conductivities in the range of 23.3-32.5m/d. The superficial aquifer is underlain by a clay-

dominated aquitard unit, which also forms a confining layer for the underlying Leederville aquifer; the

two aquifers are not expected to be in hydraulic continuity with each other in the Site vicinity.

Leederville Aquifer

The Leederville aquifer is a multi-layered confined aquifer system comprising discontinuous interbedded

sequences of sandstone and clay. The various sub-aquifers within the Leederville Formation are generally

in hydrogeological continuity with each other. Its average thickness regionally is between 150 and 200m

over most of the Hirschberg (1987) study area. The horizontal hydraulic conductivity of sandstone beds

in the Leederville aquifer, derived from pumping tests (Davidson, 1995), is about 10m/d, and that of the

siltstone and shale beds is assumed to be about 1 x 10-6 m/d. If the interbedded sandstones, siltstones

and shales are laterally extensive, the average horizontal hydraulic conductivity of the aquifer will

approach 5m/d (as the sandstones constitute approximately half the aquifer thickness). Sandy beds that

comprise the Vasse Member constitute the main aquifer. The sandy beds underlie the Mowen Member

which comprises an aquitard. Hirschberg (1989) reports that upward leakage occurs into the superficial

aquifer from the confined aquifers in the vicinity of the Site, although later studies suggest that downward

flows have also been occurring since that time, potentially due to ongoing regional abstraction from the

Leederville Aquifer (Schafer, Johnson, & Kern, 2008). The Leederville aquifer extensively outcrops

throughout the Blackwood Plateau (Schafer, Johnson, & Kern, 2008). The seasonal fluctuation of the

potentiometric heads in the Leederville aquifer is generally in the range of 1 to 2m (Hirschberg, 1989).

Discharge occurs offshore and, over an area of upward hydraulic gradient that extends several km inland,

6

by upward leakage into the superficial aquifers (Hirschberg, 1989). Hirschberg (1987) notes that salinity

in the upper 100m of the Leederville aquifer is generally less than 500 mg/L TDS and is again dominated

by sodium and chloride ions. Silica is also noted as being generally greater than normal background

concentrations, with a maximum of 50mg/L recorded by Hirschberg (1987) during his study. Water from

the Leederville aquifer is used extensively for private and municipal water supplies.

Based on the measured groundwater levels for the Superficial and Leederville Aquifers shown on Figure

4 and Figure 5, there is generally a 2m or greater difference in equipotentials between the groundwater

systems at the Site, with lower elevations recorded within the Leederville Aquifer. There are also some

instances of upward hydraulic heads and artesian flows in the vicinity of the Site, including reportedly in

one bore to the south of the Site (bore Lot 667_WM1).

Yarragadee Aquifer

The Yarragadee aquifer is composed primarily of non-marine fluvial feldspathic, poorly sorted sandstones

which are porous and poorly cemented and, hence, allow for considerable groundwater reserves. It

grades from a shale-siltstone dominated base to a cleaner sandstone in the upper portions of the

Formation, probably representing increased subsidence or filling of the basin during the late Jurassic

(Varma, 2009). Individual sandstone sections are typically 20m or more thick, and are separated by shale

beds generally up to 10m thick (Hirschberg, 1989). The Yarragadee Formation is divided into four units.

Unit 3, which underlays the Vasse Member in the proposed mining area is reported to be the most

transmissive unit (Baddock, Vine, & Leathersich, 2005). However, isotopic dating of groundwater

indicates an average hydraulic conductivity of 8m/d. Salinity in the Yarragadee aquifer is in the range of

230 to 900mg/L TDS and percentages of the major ions are similar to those in the Leederville aquifer,

suggesting a close relationship between the two aquifers. Water from the Yarragadee aquifer is primarily

for use in town drinking water and for heavy mineral sand processing in the area.

The Superficial and Leederville aquifers are located in close proximity to the proposed disturbances at

the Yalyalup deposit. The Yarragadee aquifer is located several hundred metres below the proposed

maximum depth of mining/dewatering (i.e.~12mbgl).

SURFACE WATER

Local Rivers

The Site is within the Wonnerup (Busselton Coast) Surface Water Management subarea and is not within

a proclaimed area for surface water management (DoW, 2009).

The Sabina and Abba Rivers are located within 1km of the Site to the southwest and northeast,

respectively. The Sabina River has been heavily modified, with flow from the upper reaches of the Sabina

River (i.e. Upper Sabina River) being diverted to the Sabina River Diversion Drain, approximately 1.5km

west of the Site. The Sabina River Diversion drain joins the Vasse Diversion drain to the northwest of the

Site, which was constructed in 1927 to divert ~65% of flow from the Sabina River and 90% of flow from

the Vasse River away from the Lower Vasse River and the Vasse Wonnerup wetlands.

The Lower Sabina River (i.e. below the diversion) and Abba River flow generally to the northwest of the

Site and discharge into the Vasse-Wonnerup wetlands, ~4.6km to the north-northwest of the Site (Figure

1). The Lower Sabina River has a total catchment area of 49km2, while the Abba River has a total

catchment area of 261km2.

The major drainage features and catchment areas relevant to the Site are shown on Figure 6. These show

that the Site is likely to be located wholly within the Sabina River catchment area, however, available

7

regional mapping indicates that the north-eastern corner may straddle the catchment divide with the

Abba River, although no evidence of surface water flows draining towards the Abba River were observed

during the HydroSolutions (2017) site visit. Furthermore, the Princefield Road drain diverts runoff

towards the Woddidup Creek and eventually to the Lower Sabina River. Previous high rainfall had led to

surface water run-off observed within the shallow field drains on the western and northern Site

boundaries, with flow observed to be occurring to the north and west respectively towards the tributary

of the Lower Sabina River.

On-Site Drainage

Numerous farm/field drains exist on Site, with three main drains identified in June 2017 to assist with

background surface water sampling. These include one drain extending along the western boundary of

the Site (‘Wonnerup Road South Drain’) and a further two located in the western-central parts of the Site

(Woddidup Creek/Drain), which are adapted from ephemeral creeks (Figure 6). These flow generally

towards the north and northwest, and join the Lower Sabina River approximately 2km downstream at

Wonnerup South Road. A discontinuous road-side drain is located along the northern boundary of the

Site following Princefield Road, which flows to the west to join the Woddidup Creek/Drain draining to the

north towards the Lower Sabina River.

Inspection of the Site by HydroSolutions (2017) confirmed that these drains have maximum depths of <1

m across the Site. Given that some static groundwater levels on Site have been reported to be very

shallow (i.e. eight wells in the area contained water levels at <2mBGL), it is possible that these drains are

connected to groundwater periodically. However, it should be noted that groundwater levels in the

vicinity of the drains are generally >2mBGL except in the far southeast corner of the Site, and that any

groundwater baseflow discharge to surface water flow in the drains would therefore be expected to be

limited (or periodically absent).

WETLANDS

Approximately 808ha (~90%) of the Site is mapped as a wetland in the Geomorphic Wetlands of the Swan

Coastal Plain dataset (DEC, 2008), all of which has been assessed as being in the ‘Multiple Use’

management category, which is described as wetlands with few ecological attributes and functions

remaining (Figure 7). The majority of the wetland area within the Site (~624ha or 77%) is mapped as

Palusplain (seasonally waterlogged flat), with small areas of Sumpland (seasonally inundated basin, ~30ha

or 3%) and floodplain (seasonally inundated flats, ~155ha or 17%). No wetlands of environmental

significance are present within the Site bounds.

The Yalyalup deposit is located ~4.6km southeast of the Vasse-Wonnerup Wetland system which is

recognised as a wetland of international importance under the RAMSAR Convention. Given the likely

northwest groundwater flow direction, the Site is generally up hydraulic-gradient from the wetland area.

Consequently, any impacts to the superficial groundwater that may occur as a result of operations at the

Site, have potential to reach the wetland.

ACID SULFATE SOIL RISK MAPPING

The Site occurs in an area depicted on DWER’s online ASS risk map as Class II ‘moderate to low risk of ASS

occurring within 3m of natural soil surface’ (www2.landgate.wa.gov.au) (Figure 8).

3. ACID SULFATE SOIL INVESTIGATION

SOIL SAMPLING METHODOLOGY

Doral undertook a targeted soil investigation in conjunction with resource definition drilling at the Site in

mid-December 2014 to assist in determining the presence and distribution of ASS at the Site and also to

characterise the various geological/geomorphological units. Drilling was undertaken using an air core drill

rig, with soil samples collected and logged by Doral at 1m intervals from 31 locations (Figure 9). The

drilling locations were spaced approximately 320m along the strike of the two deeper strandlines and

drill holes were located at 80-120m spacing’s across the widths of the anticipated deeper ore zones. The

depth of drilling at each location was targeted to approximately 2m deeper than the anticipated

maximum depth of disturbance, with a maximum drilling depth of 13mBGL.

Following logging of the soil profile, soil samples were collected for initial screening via field testing (pHF

and pHFOX). Samples were placed in clearly labelled snaplock bags with air excluded and placed in a 12V

vehicle freezer whilst on site, allowing the samples to be stored below 0°C. Engraved sample tag labels

were also included with all soil samples in the event sample names rubbed off the ziplock bags in transit.

The samples were initially analysed for pHF at Doral’s laboratory, prior to being stored in Doral’s chest

freezer (due to Christmas closure of the laboratory). All samples were then transported to the Australian

Government National Measurement Institute laboratory for analysis of pHFOX before being placed on cold

storage at the laboratory pending decisions about further analytical analysis.

SOIL SAMPLE ANALYSIS

Soil samples were recovered at 1m intervals and field tests were performed on all 302 primary samples

(pHF in the field, and pHFOX in the laboratory). The procedure used for field testing is discussed in detail in

Hey et al. (2000) and DER (2015a). Following field testing, 75 of the 302 primary samples (approximately

25%) were selected for laboratory analysis using the Chromium Reducible Sulfur (CRS) suite method.

Detailed analysis by CRS suite is used to determine whether soils are likely to generate net acidity, and if

so, to quantify this acidity for comparison with action criteria used to determine management

requirements. The CRS method is considered very reliable, and is less subject to interference from

sulfides in organic matter or sulfate minerals. This method was selected primarily due to the site lithology

which was observed to be clayey in nature.

SOIL ASSESSMENT CRITERIA

The ASS characteristics at the site were compared with guidance criteria provided in DER (2015a).

3.3.1 FIELD TEST CRITERIA

The results of field tests are considered to give an indication of which samples may represent ASS

material. The DER recommend that soils which have low pH values (pHF of <4, or pHFOX of <3), or which

exhibit a significant change in pH (ΔpH, as pHf – pHfox) may indicate a soil with ASS characteristics (DER,

2015a).

As such field test results were compared with the following criteria to identify potential ASS horizons:

• A pHF of 4 or less;

• A pHFOX of 3 or less;

• A change in pH value (ΔpH) of at least 3 units.

9

3.3.2 NET ACIDITY CRITERIA

Net acidity (NA) results were calculated using the equations presented in Acid Sulfate Soils Laboratory

Methods Guidelines (Ahern et al., 2004). The NA is calculated as the sum of actual acidity and potential

acidity, as well as retained acidity (for low pH samples) and is used to characterise the current state and

acid producing potential of the soils. Acid neutralising capacity is not included in the net acidity

calculations, consistent with DER (2015a) guidance.

Actual acidity is available for release into the environment in the short term and is represented by

Titratable Actual Acidity (TAA) values, using the CRS method, while potential acidity is represented by SCR

values. The pHKCl of a sample is used to determine the net acidity equation, which varies for samples with

alkaline pH (net acidity = potential acidity), near neutral pH (net acidity = actual + potential acidity), and

acid pH (net acidity = actual + potential + retained acidity).

The NA results are compared to the DER (2015a) action criterion of 0.03%S (for projects where more than

1,000 tonnes of soil will be disturbed). If results exceed this criterion, it requires the preparation of an

ASS Management Plan (ASSMP).

SOIL RESULTS

The data obtained from soil logs, field testing and CRS analysis is presented in Appendix 1. Chain of

custody documentation and laboratory certificates are provided as Appendix 2.

3.4.1 FIELD TEST RESULTS

Field test results are summarised as follows:

• Field pH (pHF) values range between 5.14 and 7.47;

• Field pH peroxide (pHFOX) values range between 1.50 and 6.90;

• The change in pH (ΔpH) ranges between -0.23 and 5.05, with an average of 3.02.

Comparison to the DER (2015a) field test criteria for all 302 primary field tests indicates the following:

• 0 primary samples with a pHF <4 were identified;

• 120 primary samples (~40% of all samples) with a pHFOX <3 were identified;

• 142 primary samples (~47%) with ΔpH of three or greater were identified.

A significant fraction of samples would be considered to represent ASS material on the basis of the field

test indicator values.

3.4.2 LABORATORY RESULTS

A total of 75 primary samples (~25% of total samples) were analysed via the CRS suite method from

samples collected from 11 investigation locations. Samples were selected based on the field test results.

The results of the laboratory CRS analyses are summarised as follows:

• One sample contained actual acidity (as s-TAA) in excess of the 0.03%S action criterion;

• 49 samples contained potential acidity (as SCR) equal to or greater than the 0.03%S action

criterion;

• Using the standard net acidity equation, NA values range from <0.01%S to 2.535%S.

Comparison of the CRS results to the assessment criteria indicates the following:

• 49 of the 75 samples analysed contained NA in excess of the 0.03%S action criteria.

10

Based on the calculated NA values, using the appropriate NA equation on the basis of the pHKCl results,

there are a total of 49 samples (65%) which exceed the 0.03%S NA action criterion, with values ranging

from 0.03%S to 2.535%S. The maximum actual acidity (as s-TAA) is 0.035%S, and the maximum potential

acidity (as SCR) is 2.5%S. The maximum NA calculated from the CRS results is 2.535%S, with an average

NA of 0.21%S for samples exceeding the DER (2015a) NA action criterion.

INTERPRETATION

Field results indicate that Site soils are generally slightly acidic to neutral as a large proportion of pHF

results are within the pH6.0 to pH7.0 range. This indicates that there is very little actual acidity present

in the soil profile, which is confirmed by the laboratory results, which show very little acidity is present

as s-TAA. However, field results also show a high proportion of samples with pHFOX <3 and a ΔpH above

3pH units, indicating that there is additional potential acidity yet to be released into the soil profile. This

is also confirmed by the laboratory CRS results which show 49 of the 75 samples analysed, contain NA as

SCR above the action criterion (0.03%S).

Elevated NA above the action criterion was generally identified at depth (i.e. greater than ~5mBGL) from

10 of the 11 locations and at three of these locations elevated NA was also identified in surface and near

surface soils. It should be noted that 41 of the 75 samples analysed by CRS were located >1m below the

maximum depth of mine pits, of which 33 exceed the action criterion. The remaining 34 samples analysed

for NA were located from soils within the ore zone of the proposed mine pits, of which 16 exceeded the

NA action criterion.

4. GROUNDWATER ASSESSMENT

GROUNDWATER MONITORING WELL LOCATIONS

Due to the preliminary nature of the Project, Doral are yet to install site-specific groundwater monitoring

wells to commence the collection of background groundwater data (quality and levels) in either the

Superficial and Leederville aquifers. Installation of these monitoring wells is planned to occur in late 2017,

with proposed locations shown on Figure 9. A network of landowner and/or DWER bores however have

been used to collect initial samples to assist in assessing the baseline quality of groundwater and its

vulnerability to acidification.

ASSESSMENT CRITERIA

Groundwater quality at the Site is compared with guidance criteria provided in (DER, 2015b) to assess

whether ASS processes may have taken place at or in the vicinity of the Site. Criteria used for this

assessment include the following:

• A sulfate: alkalinity ratio greater than 0.2;

• A pH less than 5;

• Soluble aluminium concentration of greater than 1 mg/L.

In addition, samples are considered in light of indicative guidelines presented in DER (2015b) regarding

the buffering capacity of groundwater, based on a review of its alkalinity and pH.

The analytical results were also compared with criteria for Australian Drinking Water Guidelines (ADWG),

Non-Potable Use Groundwater (NPUG), and the Fresh Water Guidelines (FWG) in due to the presence of

the Sabina River. These criteria are summarised in DWER’s document Assessment and Management of

Contaminated Sites (DER, 2014).

ANALYTICAL RESULTS

A summary of groundwater analytical results in comparison to the relevant assessment criteria are

presented below in Table 1 for the Superficial aquifer and Table 2 for the Leederville aquifer.

4.3.2 LEEDERVILLE AQUIFER GROUNDWATER RESULTS

A comparison of the results to the ASS indicator criteria indicates the following for the Leederville aquifer

quality:

• pH values range from 5.35 to 6.47, with an average of 5.95 and do not exceed the ASS indicator

value of pH5.0;

40mgCaCO3/L, with concentrations ranging from 45-190 mgCaCO3/L;

• Total alkalinity concentrations range from 21-91mgCaCO3/L, indicating that groundwater is

• The pH of all samples is below the recommended range of 6.5-8.5;

• Nine of the 15 samples exceed the dissolved aluminum criteria of 0.0055mg/L;

• Fourteen of the 15 samples exceed the dissolved iron criteria of 0.03mg/L.

INTERPRETATION

Groundwater results from initial groundwater monitoring undertaken by Doral, indicate that Superficial

groundwater quality beneath the Site is slightly acidic due to pH levels generally <6.0 (although above

the ASS indicator value of pH5.0), elevated total acidity concentrations of up to 110mgCaCO3/L and

moderate total alkalinity concentrations. The alkalinity/sulfate ratio indicates that groundwater is being

affected by, or has already been affected by, the oxidation of sulfides. Moderate alkalinity concentrations

coupled with a pH of <6.0 indicates groundwater is generally inadequate to maintain a stable pH in areas

vulnerable to acidification. It is also noted that the alkalinity concentrations are approximately equal to

the total acidity concentrations, indicating that some buffering capacity is present within the system to

offset some of the acidity.

Groundwater quality in the Leederville Aquifer is also considered to be acidic as evidenced by the high

total acidity concentrations (up to 190mgCaCO3/L) and pH generally <6.0. Alkalinity concentrations are in

the low to moderate range indicating that groundwater is inadequate to maintain a stable, acceptable

pH level. The alkalinity/sulfate ratio also indicates that groundwater is being affected by, or has already

been affected by, the oxidation of sulfides.

5. MINING AND DEWATERING PROCCESS

The mining activities will be scheduled to be undertaken on a campaign basis, with a portion of the ore

body being mined and processed in a discrete time period. During each campaign, ore from the targeted

area of the deposit will be mined progressively via a series of open-cut pits using dry mining techniques.

Once the topsoil and subsoil are stripped and stockpiled, overburden (if present) will be removed via

excavator and truck. Removed overburden will be stockpiled or where possible used in progressive

rehabilitation of previously mined areas (i.e. backfilled into mine pits). Exact depths of ore and

overburden will vary for each pit, but will not exceed ~12mbgl. Ore will be mined in a series of lifts, to a

maximum depth of ~12mbgl. Additional infill drilling may indicate localised areas where the Yoganup

strand ore might exceeds this indicated depth. Pits will be mined on a slight incline from the deepest

point and then mined moving up gradient in order to retain pit water within a sump at the deepest point

on the pit floor. This form of dewatering is known as ‘passive’ as no dewatering apparatus (e.g. spears)

are used to actively abstract water and groundwater drawdown below the base of the pit (i.e. below

12m) is highly unlikely to occur. Only suction pumps (no submersible pumps) are used for dewatering

and the suction pumps are set up at a level to maintain a 0.5m saturated pit floor. Mine pit dewater is

pumped from the sump to the process water pond (PWP) for reuse.

Near surface dunal sand ore will be mined from the face using a Front End Loader in a single lift, and fed

into the in-pit hopper, and screened and slurried using a mobile in-pit screening unit. The ore sourced

from the deeper Yoganup strands will be mined using excavtors and trucks to a central ROM pad (then

feed into a fixed location feed unit). Alkaline (lime sand) material may also be added into the in-pit hopper

during the excavation of ore to increase/maintain the pH (pH6.0) and buffering capacity within the wet

concentration process and outgoing sand tails. The screened slurry is then pumped to the feed

preparation plant where it will move through a trommel and scrubber for removal of material greater

than 3mm. Oversize materials (i.e. > 3mm) will be returned to the pit void or used to sheet internal mine

site roads.

From the feed preparation plant, the ore will be transported via pumps and pipelines to the wet

concentration plant where the process requires all particles >2.4mm to be removed from the ore.

Approximately 500,000 to 700,000t of HMC is expected to be produced over the life of mining. The HMC

is stockpiled onsite and the moisture content is then reduced by allowing the stockpile to drain, prior to

transportation to the Picton Dry Separation Plant.

Two waste streams are produced from the wet concentration plant; sand tails and clay slurry. Sand tails

(including the lime sand added to the in-pit hopper) are hydraulically returned as a slurry to the mine pits

as rapidly as possible to maximise rebound of groundwater levels. The clay slurry is directed to the

thickening circuit, where flocculent agglomerates clay fines, producing clay slurry.

Clay tails are either pumped into solar evaporation ponds (SEPs) to allow settlement and drying or co-

disposed with sand tails. Dried clay tails from the SEPs will be removed from the ponds (during the dry

months) and placed in-pit with sand tails. Where possible co-disposal of clay fines and sand tails will be

undertaken during mining whereby the clay tails is disposed with the sand tails into the pit voids at the

same time. This provides a more heterogeneous distribution of soil particle sizing and improves the

hydraulic conductivity and permeability of the returned soil profile. The majority of the water will be

decanted from the SEPs and pumped or gravity fed back to the PWP for use as process water.

18

6. SOIL MANAGEMENT STRATEGY

The Yalyalup deposit is mapped as Bassendean Sands in an area mapped as having a moderate to low risk

of ASS (Class II) occurring within 3m of the natural soil surface. Results derived during Doral’s ASS

investigation show that site soils proposed for excavation and dewatering contain NA in excess of the

DWER’s action criterion of 0.03%S. Therefore, soils will require management once excavation activities

begin.

The general sequence of mining and processing is as follows:

1. Removal and stockpiling of topsoil and subsoil;

2. Either overburden or mineral sands ore will be excavated:

a. For strand deposit ore, which is overlain by several metres of overburden, initial

excavation will be to remove overburden:

i. Overburden, where present, will be re-buried into a pre-existing mine void,

within 70 hours of excavation or will be stored and managed appropriately prior

to re-burial or re-use onsite;

ii. Excavation and processing of ore commences.

b. Where ore is present at surface, such as for dunal deposit materials, excavation and ore

processing will commence immediately.

3. For all ore that is excavated, processing commences when the material is fed into the in-pit

hopper, with the addition of lime sand (as necessary to maintain process materials at pH6.0), and

transported as a wet slurry to the wet concentration plant;

4. Processing of the slurried materials results in the ore materials being separated into three

process streams; HMC, sand tails and clay fines:

a. The HMC is initially stockpiled onsite prior to transport off-site for further treatment at

Doral’s Picton Dry Plant;

b. The clay fines and sand tails waste streams are managed either by co-disposed into mine

voids or managed as waste material (in SEPs) prior to being disposed on-site into mine

voids that have been created.

In addition to the general sequence of mining and processing, if necessary, unprocessed materials may

be utilised for construction of roads or infrastructure, with the material being referred to from herein as

‘’construction material’’.

The soil management strategies presented here are intended to minimise the risk of ASS impacts.

TOPOSIL AND SUBSOIL MANAGEMENT

Topsoil and subsoil will be stripped to a depth of approximately 100mm and stockpiled, prior to use in

progressive rehabilitation. In accordance with DER (2015b), topsoil will not require neutralisation if the

pH of surface soils (0-0.3m) is less than pH4.0. Should the pH of this material be less than pH4.0,

neutralisation will be undertaken using suitable alkaline material to ensure a revised validation criterion

of pH5.0 is achieved.

19

OVERBURDEN MANAGEMENT

The strandline deposit ore at Yalyalup is overlain by approximately 2-5m of overburden which requires

excavation and management prior to excavation and processing of ore.

On the basis that overburden will not be processed, any overburden that has been identified as ASS (i.e.

NA > 0.03%S) will be reburied as soon as possible below the natural groundwater level into a mine void

that is being actively backfilled with sand tails and/or clay fines resulting from ore processing. The sand

tails and/or clay fines are hydraulically returned over the overburden, maintaining the overburden

material to anoxic conditions and providing additional buffering capacity, as a result of the addition of

lime sand during the excavation and processing of ore. The addition of this alkaline material during

backfill of overburden is a form of in situ treatment as it allows a homogenous application of additional

alkalinity to be applied to the overburden material.

Overburden identified as ASS that cannot be immediately backfilled will be excavated and temporarily

stored in-pit on a guard layer of alkaline material for less than 70 hours prior to being re-buried below

the natural groundwater level into a mine void that is being actively backfilled with sand tails and/or clay

fines (i.e. equivalent to DWER’s short-term stockpiling timeframe).

Overburden identified as ASS that is unable to be re-buried with within 70 hours will be stockpiled on a

treatment pad prior to neutralisation treatment at an appropriate rate based on the NA of the material,

and will be re-buried within 21 days (i.e. DWER’s medium-term stockpiling timeframe). The treatment

pad will be constructed of compacted crushed limestone of not less than 300mm thickness, be graded to

ensure good drainage, and all sides will be bunded with limestone or similar alkaline material to a

minimum height of approximately 150mm above the surface of the pad to prevent lateral run-off. A

leachate collection system will also be present to manage run-off from rainfall events.

It should be noted that overburden excavated from below the natural groundwater level will be

maintained in an anoxic state prior to excavation as a result of the passive dewatering method. As a

result, this overburden will be excavated in a saturated state, reducing potential for oxidation of sulfidic

acidity that may be present.

ORE MANGEMENT

Excavated ore that has been identified as ASS (i.e. NA >0.03%S) will be processed through the wet

concentration plant as soon as possible. As this material is maintained in the form of a wet slurry (i.e.

saturated), the risk of sulfide oxidation is greatly reduced and as such will not require any active soil

management if in this state. The process slurry is maintained at pH6.0 to assist with the separation

process. As such, alkaline (lime sand) material will be added into the in-pit hopper during the excavation

of ore to maintain pH6.0 and increase buffering capacity within the wet concentration process. Unused

(unreacted) lime sand becomes a portion of the outgoing sand tails, resulting in the addition of buffering

capacity to this waste stream. The rate at which lime sand is added to the in-pit hopper will be

determined through pit dewater, wet plant thickener and/or tails return water field pH monitoring.

Any ore material that is not processed immediately upon excavation will be placed on a guard layer of

alkaline material and stockpiled for a period of no more than 70 hours (i.e. short-term stockpiling

timeframes). Ore that cannot be processed within 70 hours will be stockpiled on a treatment pad

(constructed as per Section 6.2) and will be processed or neutralised within 21 days (i.e. medium-term

stockpiling timeframe).

20

PROCESSED MATERIALS MANAGEMENT

Processing of ore results in three streams of material, HMC, clay fines and sand tails. The three processed

streams are then dealt with in the following manner:

• HMC is stockpiled and stored on-site until transport to Doral’s Picton dry processing plant for

further processing;

• Sand tails are hydraulically returned into pit voids (including as co-disposal);

• Clay fines are either hydraulically co-disposed with sand tails into pit voids or directed to SEPs to

be consolidated for future disposal into mine voids.

Management of each of the process streams is detailed in the following sections.

6.4.1 HMC

The HMC resulting from processing will be stockpiled and stored on a bunded alkaline pad, as described

in Section 6.2, until it is transported offsite. Leachate emanating from the stockpiled HMC will be

captured and returned to the ore processing circuit, which is maintained at pH6.0.

6.4.2 SAND TAILS

Sand tails resulting from ore processing will be hydraulically returned to pit voids as a single waste stream

and/or co-disposed with clay fines into pit voids. This material will have been maintained in a saturated

state and with conditions maintained at pH6.0 throughout the process. Furthermore, the unused

(unreacted) lime sand that was added to the process at commencement of the ore processing sequence

(i.e. at the in-pit hopper) will form part of this process stream, resulting in the addition of buffering

capacity to the locations where this material is hydraulically returned.

Sand tails will be regularly tested to ensure that the inherent acid neutralising capacity of this waste

stream exceeds the acidity present. If necessary, additional lime sands will be incorporated during

hydraulic disposal.

6.4.3 CLAY FINES

Clay fines will be managed by either:

• Immediate co-disposal with sand tails by hydraulic return in existing mine voids; or

• Directed to a SEP for storage and future use as void backfill.

Clay fines that are immediately co-disposed with sand tails will be maintained in a saturated state prior

to disposal and will include additional buffering capacity provided by the unused (unreacted) lime sands

within the sand tails material. This material will be regularly tested to ensure that the acid neutralising

capacity exceeds the acidity present in this waste stream.

Clay fines material that are directed to the SEPs will also be regularly tested to ensure the acid neutralising

capacity exceeds acidity of the waste stream. If insufficient buffering capacity is identified, additional

neutralising material (lime sand) will be added prior to being discharged into a SEP. In addition to regular

testing during discharge, this material will be re-tested following consolidation and drying within the SEP,

prior to final disposal. The purpose of the pre-disposal testing is to ensure the pH and acid neutralising

capacity of material is adequate to mitigate post-disposal risk to the receiving environment. Leachate

from the SEP’s will be directed back towards the ore processing circuit, which is maintained at pH6.0.

21

CONSTRUCTION MATERIAL MANAGEMENT

Overburden and non-processed material identified as ASS (i.e. NA >0.03%S), that will be used for site

construction purposes (i.e. roads, pads, bunds etc) will either be:

• Neutralised for re-use within 70 hours of excavation; or

• Stockpiled on a treatment pad (as described in Section 6.2) for up to 21 days prior to

neutralisation and re-use.

Neutralisation and validation sampling of this material will be undertaken using the rates and criteria

provided in Section 6.6.

CONSTRUCTION MATERIAL NEUTRALISATION RATE AND VALIDATION

Table 3 presents the uncorrected neutralisation rate calculated using the following equation:

Lime required (kg CaCO3/m3) = Soil density (t/m3) x NA (%S x 30.59) x 1.02 x safety factor (1.5) x 100/ENV

It should be noted that this liming rate is provided as a guide only, as it is based on samples analysed for

CRS at depth (i.e. greater than ~5mBGL) and not of the actual overburden material. Doral intends to

characterise the NA of overburden material during infill drilling in late 2017 to provide a more accurate

liming rate.

TABLE 3: LIMING RATE CALCAULATION

A: Soil Density (tonne/m3) 1.65

B: NA (%S) 0.66

C: Conversion Factor (%S to kg lime/tonne soil, including 1.5 x safety factor) 46.80

A*B*C: Uncorrected Liming Rate (kg CaCO3/m3 soil) 51.0

The liming rate presented in Table 3 has been calculated using an assumed bulk density of 1.65 t/m3 and

the average plus one standard deviation NA values for soils exceeding the action criterion at the Site

(0.66%S); it is uncorrected for effective neutralising value (ENV). That is, uncorrected liming rates assume

that the treatment will be undertaken using pure calcium carbonate which can all be directly utilised. As

aglime (also known as lime sands), the most common agent, is not 100 % calcium carbonate and has

particle size variations leading to a reduction in its chemical availability, the values presented in Table 3

will need to be corrected for ENV. A lime certificate providing information about the neutralising value

and particle size distribution of the neutralising agent will be required. This is to be provided by the

supplier. As an indication, the effective neutralising value of commonly available aglime/limesand may

be in the order of 70%, which would yield a corrected liming rate of approximately 87kgCaCO3/m3 soil.

Treated material will be subject to validation sampling at a rate consistent with (DEC, 1996) guidance in

Landfill Waste Classification and Waste Definitions 1996 (As amended). Samples are to be undertaken to

represent ‘batches’ of treatment.

All samples are to be assessed for pHF and pHFOX. The accuracy of the field testing program should be

initially ‘calibrated’ by sending approximately 25% of samples for additional laboratory analysis by

SPOCAS suite or CRS suite with inclusion of TPA analysis from SPOCAS suite.

Samples meeting the following criteria (DER, 2015b) will be deemed to be effectively neutralised:

22

1. Visually, the neutralising material must be well-blended with the soil.

2. Samples require a pHF of between 6.0 and 8.5.

3. Samples require a pHFOX of at least 5, to indicate that there is neutralising capacity greater than

the existing plus potential acidity of the soil.

4. Laboratory results need to indicate that excess acid neutralising capacity is present, as evidence

that acidity released in the future can be neutralised.

SAND TAILS NEUTRALISATION AND VERIFICATION

Sand tails will include unused (unreacted) lime sands resulting from the addition of lime sands to the

excavated ore material at the in-pit hopper. The sand tails will also be co-disposed with clay fines. The

incorporation of this material into the sand tails will result in the addition of acid neutralising capacity to

the receiving environment of the sand tails.

Testing of the sand tails waste stream will be undertaken to ensure the material has been effectively

neutralised, as per the following criteria:

1. Co-disposed materials must be well mixed prior to hydraulic reburial.

2. Samples require a pHF of between 6.0 and 8.5.

3. Samples require a pHFOX of at least 5, to indicate that there is neutralising capacity greater than

the existing plus potential acidity of the soil.

4. Laboratory results need to indicate that excess acid neutralising capacity is present, as evidence

that acidity released in the future can be neutralised.

CLAY FINES NEUTRALISATION AND VERIFICATION

Clay fines will be either co-disposed with sand tails into the mine voids or directed to a SEP for

consolidation prior to final disposal into a mine void.

Clay fines sent to a SEP will be managed by addition of sufficient alkaline material to ensure that the acid

neutralising capacity exceeds the acidity present within this material. Clay fines that are co-disposed will

be treated by mixing with sand tails and/or by addition of appropriate alkaline material (lime sand) to

ensure the material has been neutralised. Testing of the clay fines waste stream will be undertaken prior

to either co-disposal in mine voids or storage in SEPS to ensure the following criteria are met:

1. Visually, the neutralising material must be well-blended with the soil.

2. Samples require a pHF of between 6.0 and 8.5.

3. Samples require a pHFOX of at least 5, to indicate that there is neutralising capacity greater than

the existing plus potential acidity of the soil.

4. Laboratory results need to indicate that excess acid neutralising capacity is present, as evidence

that acidity released in the future can be neutralised.

Clay fines that are contained within the SEPs will also be tested prior to disposal into mine voids and if

necessary be treated by addition of alkaline material (lime sand), to ensure that sufficient acid

neutralising capacity is present in to overcome future oxidation of sulfidic material. The aforementioned

criteria must be met prior to removal or disposal of consolidated material from the SEPs.

23

DOCUMENTATION OF SOIL MANAGEMENT

Documentation of soil management will be maintained as follows:

• Source and volume of ASS material requiring neutralization;

• Source and volume of neutralising material used;

• Verification sampling undertaken;

• Final location of treated material.

24

7. DEWATERING MANAGEMENT STRATEGY

DEWATERING PROCESS AND EXTENT

Dewatering to the required depth of excavation will occur passively as groundwater enters the mining

excavation. The water will be pumped out using a suction pump set at a level to maintain a 0.5m

saturated pit floor and sent through to a sump prior to reaching the unlined process water pond where

it mixes with other water from other mine processes. The use of passive dewatering reduces the extent

of groundwater drawdown as far as practical.

The extent of groundwater drawdown is also reduced by recharge resulting from the hydraulic backfill of

the pit voids with sand tails and clay fines. The pit backfilling acts to recharge groundwater levels rapidly,

compared to unassisted rebound by aquifer hydraulic head pressures only. The expedited recharge,

thereby reduces the extent of dewatering influence and returns the soil profile to anoxic conditions.

Unreacted lime sand that was added to the ore slurry at the in-pit hopper (to ensure the process stream

pH is maintained at pH6.0) also ends up in the sand tails waste stream, assisting to buffer the pH of the

groundwater system as rebound occurs.

DEWATERING MONITORING

One sample point will be established to monitor the dewatering effluent quality at a location prior to the

water reaching the process water pond (pit dewatering sump) and a second sample point will be

established at the process water pond.

The following monitoring program will be conducted for the pit dewatering sump (pre-treatment) and

process water dam (post-treatment):

• Field testing for pH, electrical conductivity (EC), total titratable acidity (TTA) and Total Alkalinity

will occur three times a week (Monday, Wednesday and Friday);

• Monthly laboratory analysis for pH, EC, TDS, total acidity, total alkalinity, dissolved aluminium,

dissolved iron and dissolved manganese.

o If total aluminium is above 1mg/L then additional laboratory analysis will be required for

the following total metals; arsenic, cadmium, chromium, copper, lead, mercury, nickel,

selenium and zinc.

DEWATERING TRIGGER VALUES AND TREATMENT

DER (2015b) guidelines require that dewatering effluent with a pH of less than pH6.0 or total acidity of

greater than 40mgCaCO3/L or total alkalinity less than 30mgCaCO3/L, be treated via addition of a

neutralising agent prior to reinfiltration (i.e. hydraulic return of sand tails and/or clay fines into mine

void).

As groundwater (from preliminary monitoring) has been shown to be slightly acidic, the following trigger

values will apply to the monitoring of dewatering effluent from the pit dewatering sump (pre-treatment)

and also within the process water pond:

• Field pH <5.5 or

• TTA >40 mgCaCO3/L; or

• Total Alkalinity <30 mgCaCO3/L.

25

Should any of these criteria be triggered, dewatering effluent will be treated via the addition of a suitable

neutralising agent. In the event that the water within the process water pond exceeds the trigger values,

active management of process water prior to reinfiltration (via clay fines and sand tails) or discharge from

the water circuit will be required.

CONTINGENCY PLAN

In the event that monitoring of the dewatering effluent reaches a trigger value listed in Section 7.3, the

initial response (apart from neutralisation) will be to increase the monitoring listed in Section 7.2 to daily

field testing and weekly laboratory testing of the affected areas.

If trigger values listed in Section 7.3 are reached at the process water pond, the initial contingency

measure will be to treat the process water through the addition of a suitable alkaline material to the

thickener until the water is above the trigger values. Whilst the process water pond is outside of the

trigger values, discharge of process water off site will cease.

Any off-site emergency discharge of water from the process water dam will be managed and monitored

through DWER licensing under Part V of the EP Act before any process water is discharged.

Monitoring of the pit dewatering sump will provide prior indication that treatment is likely to be required

at the process water dam. If the trigger values listed in Section 7.3 in the pit dewatering sump (pre-

treatment) are exceeded, the contingency action will be to add a neutralising agent to the thickener.

26

8. GROUNDWATER MANAGEMENT STRATEGY

The disturbance of ASS material can lead to the release of acid and mobilisation of metals, causing

contamination of groundwater which may cause offsite impacts to groundwater and groundwater

dependent ecosystems. Indirect disturbance via dewatering is a primary concern, as areas of the site

contain ASS material below the usual groundwater table interface which may be exposed to oxidation via

dewatering. Indirect acidification via dewatering may lead to acidic or metal-rich groundwater plumes

which may affect onsite or offsite receptors. In order to identify potential groundwater impacts,

monitoring of groundwater quality will take place, and the results will be compared against baseline

values. If required, contingency measures will be developed and implemented.

GROUNDWATER MANAGEMENT

As the ore body is mined using dry mining techniques, the ore located below the natural groundwater

table, will need to be dewatered. Although the dewatering process will be passive, reducing the radius

of influence of dewatering compared to active dewatering (i.e. such as spears), a significant area will

eventually be impacted by the passive dewatering, including areas adjacent to the Sabina River, and

wetland areas within the site. It is therefore considered appropriate to monitor groundwater to assess

possible impacts of the reduction in groundwater levels during mining.

GROUNDWATER MONITORING WELLS

At present no groundwater monitoring wells have been installed at the Site. Doral plan to install site-

specific groundwater monitoring wells up-gradient and down-gradient of mining areas towards the end

of 2017 within the Superficial Aquifer (Figure 9). These wells will be used to develop trigger criteria and

monitor changes in groundwater levels and quality.

GROUNDWATER MONITORING PROGRAM

The following monitoring program will be conducted during dewatering operations for the proposed

groundwater monitoring wells:

• Monthly monitoring of groundwater levels;

• Monthly field testing for pH, EC, TTA and temperature;

• Monthly laboratory analysis for pH, EC, TDS, total acidity, total alkalinity, chloride, sulfate,

dissolved aluminium, dissolved iron and dissolved manganese (If Al >1 mg/L then the sample will

also be analysed for As, Cd, Cr, Cu, Pb, Hb, Ni, Se, Zn).

The results will be compared to site-specific assessment criteria (yet to be developed), which will be

based on baseline monitoring results.

At the completion of dewatering operations, groundwater monitoring will continue as above for six

months (or until any adverse trends have stabilised) then on a quarterly basis for an additional 12 months.

GROUNDWATER ASSESSMENT CRITERIA

It is proposed that site-specific groundwater assessment criteria will be developed for each of the

proposed monitoring wells using background data that is to be collected in the 12-month period

preceding the commencement of mining. The assessment criteria will be set using the mean laboratory

data plus/minus two standard deviations for relevant ASS parameters.

27

TRIGGER CRITERIA

The trigger values are inherently conservative and the initial response to an exceedance by any parameter

will be to establish the context of the exceedance and determine whether the result requires re-

sampling/analysis, immediate further action, or no response at all. A key measure for the context of an

exceedance is to consider whether multiple triggers are exceeded.

Initial response to exceedance of any trigger value will be:

• Review exceedance in relation to any site wide changes or trends in key ASS risk parameter (pH,

TTA and TAlk);

• Review sample collection, handling and analysis methods and procedures to ensure appropriate

methods were used;

• Review groundwater level data, dewatering effluent quality data and current mining operations

to consider possible causal factors;

• If necessary, re-sample affected locations as soon as practical (i.e. within 2-weeks) to confirm

whether or not the groundwater quality parameter(s) exceed the trigger value;

• Increase on-going monitoring frequency of the affected monitoring well(s).

Secondary responses will be developed based upon situation specific outcomes from the initial

responses, but will include the following immediate further action responses:

• If it is confirmed that the pH and TTA exceed trigger criteria in successive sampling events, the

sampling frequency for field parameters will be increased to fortnightly; and/or

• When it is confirmed that any other groundwater quality parameters have deteriorated to levels

outside of the background based trigger levels; then

• Inform DWER that contingency monitoring is being undertaken; and

• Prepare a contingency action plan suited to the level of risk that confirmed adverse groundwater

quality poses to potential receiving environments, such as down gradient groundwater users or

environmental receptors.

REPORTING

The monthly groundwater monitoring results will be compared to trigger levels within 7 days of receipt

of analytical results. The presence or absence of results that exceed trigger values will be recorded on a

monthly groundwater log. If contingency measures are required, the initial response and or any

secondary responses will be recorded in the groundwater log within 24 hours.

The groundwater log, field results and laboratory documentation of each year will be reported in the

Annual Environmental Report (AER).
