1.0 INTRODUCTION
1.1 Background RGS Environmental Pty Ltd (RGS) was commissioned by Hansen Bailey on behalf of BHP Billiton Manganese Australia Pty Ltd to complete a geochemical assessment of ore and mine waste materials as part of the Environmental Impact Statement (EIS) for the Eastern Leases Project (the project). Thegeochemical assessment has been developed as a stand-alone document suitable for inclusion in theEIS document to support an approval application for the project.
The project proponent is the Groote Eylandt Mining Company Pty Ltd (GEMCO), which has two shareholders, namely South32 Pty Ltd (60%) and Anglo Operations (Australia) Pty Ltd (40%). BHP Billiton Manganese Australia Pty Ltd was previously a shareholder in GEMCO, however its interest is now represented by South32.
The project involves the development of a number of open cut mining areas to the east of the existing GEMCO manganese mine on Groote Eylandt in the Gulf of Carpentaria, approximately 650 km south-east of Darwin (Figure 1). The proposed additional mining areas are located on the Eastern Leases, which are two Exploration Licences in Retention (ELRs). ELR28161 is termed the Northern Eastern Lease (Northern EL) and ELR28162 is termed the Southern Eastern Lease (Southern EL).
The Eastern Leases are located 2 km east of the existing GEMCO mine at the closest point. The township of Angurugu is located approximately 6 km to the north-west of the Eastern Leases, and is the closest residential community (Figure 2). The Eastern Leases are located on Aboriginal land, scheduled under the Aboriginal Land Rights Act (Northern Territory) 1976. The land within the Eastern Leases comprises natural bushland, with the Emerald River and a small section of the Amagula River traversing the Northern EL and Southern EL respectively.
The project involves:
developing a number of open cut mining areas (termed “quarries”) within the Eastern Leases and mining manganese ore by the same mining methods that are in use at the existing GEMCO mine;
constructing mine related infrastructure in the Eastern Leases (dams, water fill points, crib hut, truck park up areas and laydown storage areas); and
transporting the ore by truck on a new haul road to be constructed between the existing GEMCO mine and the Eastern Leases.
Quarry development will involve the removal of overburden and interburden associated with the manganese ore. All overburden will be emplaced in mined quarry areas, or may be temporarily emplaced in out-of-pit emplacement areas until quarry areas are available for backfilling and rehabilitation. Interburden is found within the horizons of the manganese ore and, depending on thickness of this material, may be handled as either overburden or ore. As interburden is geologically comparable to overburden and geochemically distinct relative to manganese ore, interburden and overburden have been assessed collectively in this report. All overburden will be emplaced in mined quarry areas, or may be temporarily emplaced in out-of-pit emplacement areas until quarry areas are available for backfilling and rehabilitation.
Ore will be processed at the concentrator at the existing GEMCO mine and the concentrate would be transported to market via the existing port located at Milner Bay (Figure 2). No changes or upgrades to the existing GEMCO mine facilities are required as a result of the project. Ore mined from the Eastern Leases will supplement production from the existing GEMCO mine, but the project will not increase GEMCO’s annual production rate of approximately 5 Million tonnes per annum of product manganese.

The processing of manganese ore from the Eastern Leases will generate tailings (sands and slimes) and middlings. GEMCO has established handling and storage methods for process residues and these methods have been operating since the commencement of operations.
The project site for the purposes of this report is the Northern and Southern ELs.
1.2 Scope of Work The primary purpose of this report is to complete a geochemical assessment of overburden (i.e. overburden and interburden) to be excavated during quarry development, and identify any environmental risks associated with this material. This material was characterised through field investigations and sample analysis. Where potential environmental risks were identified, conceptual management strategies have been developed by RGS to ensure that these risks are addressed.
As noted in Section 1.1, ore from the project will be stockpiled at the existing GEMCO mine and processed at the concentrator, also located at the existing GEMCO mine. The tailings and middlings generated by this process will be managed in accordance with GEMCO’s current management strategy for tailings and middlings. In general, the EIS does not include any assessment of operations within the existing GEMCO mine, given that these operations are subject to existing environmental approvals, and will not be altered by the project. However, in accordance with the EIS Terms of Reference (TOR) that the NT Environment Protection Authority (NT EPA) has prepared for the project (NT EPA, 2014), this report includes geochemical characterisation of manganese ore, tailings and middlings. This assessment was prepared following a review of available geochemical data from the existing GEMCO mine, supplemented by targeted sampling and analysis of middlings materials from the existing operations.
The scope of this assessment is summarised as follows:
Review available geochemical data, geological data and existing exploration and groundwater drilling databases (including plans, drill hole logs and drill core photographs) relevant to the project site;
Design a geochemical assessment program including sampling and testing requirements for representative materials from the project site;
Coordinate the material sampling program and geochemical analysis programs;
Geochemically characterise representative samples of overburden, ore and middlings materials;and
Prepare a Geochemistry Report (this report) identifying any environmental risks related to the geochemistry of project materials.

2.0 PROJECT SITE SETTING
2.1 Location and Topography The land within and surrounding the project site comprises natural bushland. No farming or agriculture activities are undertaken within, or in the vicinity of the project site.
GEMCO has been undertaking manganese exploration activities across the Eastern Leases site since 2001. The geology of the Eastern Leases is discussed in Section 2.2.
The topography across the project site varies from level to undulating plains, to sandy colluvial footslopes with rugged uplands. Elevations range from approximately 10 m Australian Height Datum (AHD) to 120 m AHD.
Several drainage lines traverse the project site, including sections of the Emerald and Amagula Rivers, and their tributaries.
2.2 Geology Groote Eylandt was formed on a stable basement of Proterozoic quartzite that outcrops over the majority of the island.
The Proterozoic basement materials were eroded and redeposited under marine conditions during the early Cretaceous period.
A blanket of Cretaceous sediments was subsequently deposited over the basement and reworked basement materials in the west of the island. The distribution of Cretaceous sediments is generally confined to the western plains of the island. The upper Cretaceous sediments contain the manganese deposits.
The manganese ore is a sedimentary layer, consisting of manganese strata occurring between clay and sand beds. The ore body is essentially stratabound and strataform in character and it represents a continuous horizon up to 11 m thick. The ore body consists of pisolitic and oolitic manganese oxides.
Much of the Cretaceous sediment profile (including some of the manganese deposits) has been extensively modified by a long period of tropical weathering (or laterisation) during the Tertiary period. This has resulted in the development of thick laterite profiles up to 25m thick.
The laterite is strongly oxidised and leached and forms the iron and alumina rich layers above the manganese ore.
The typical stratigraphy of the project site is provided in Figure 3 and comprises (in reverse chronological order):
A thin veneer of Quaternary sediments;
A weathered profile of Tertiary laterite and lateritic clays;
Cretaceous marine clays including the manganese ore;
Cretaceous marine sandstone;
Cretaceous sandstone of reworked quartzite basement; and
the underlying Proterozoic quartzite basement.
The relative depth and thickness of each sedimentary unit varies across the Eastern Leases depending on the depth of the underlying Proterozoic basement.

The processing of manganese ore from the Eastern Leases will generate tailings (sands and slimes) and middlings. GEMCO has established handling and storage methods for process residues and these methods have been operating since the commencement of operations.
The project site for the purposes of this report is the Northern and Southern ELs.
1.2 Scope of Work The primary purpose of this report is to complete a geochemical assessment of overburden (i.e. overburden and interburden) to be excavated during quarry development, and identify any environmental risks associated with this material. This material was characterised through field investigations and sample analysis. Where potential environmental risks were identified, conceptual management strategies have been developed by RGS to ensure that these risks are addressed.
As noted in Section 1.1, ore from the project will be stockpiled at the existing GEMCO mine and processed at the concentrator, also located at the existing GEMCO mine. The tailings and middlings generated by this process will be managed in accordance with GEMCO’s current management strategy for tailings and middlings. In general, the EIS does not include any assessment of operations within the existing GEMCO mine, given that these operations are subject to existing environmental approvals, and will not be altered by the project. However, in accordance with the EIS Terms of Reference (TOR) that the NT Environment Protection Authority (NT EPA) has prepared for the project (NT EPA, 2014), this report includes geochemical characterisation of manganese ore, tailings and middlings. This assessment was prepared following a review of available geochemical data from the existing GEMCO mine, supplemented by targeted sampling and analysis of middlings materials from the existing operations.
The scope of this assessment is summarised as follows:
Review available geochemical data, geological data and existing exploration and groundwater drilling databases (including plans, drill hole logs and drill core photographs) relevant to the project site;

2.0 PROJECT SITE SETTING
2.1 Location and Topography The land within and surrounding the project site comprises natural bushland. No farming or agriculture activities are undertaken within, or in the vicinity of the project site.
GEMCO has been undertaking manganese exploration activities across the Eastern Leases site since 2001. The geology of the Eastern Leases is discussed in Section 2.2.
The topography across the project site varies from level to undulating plains, to sandy colluvial footslopes with rugged uplands. Elevations range from approximately 10 m Australian Height Datum (AHD) to 120 m AHD.
Several drainage lines traverse the project site, including sections of the Emerald and Amagula Rivers, and their tributaries.
2.2 Geology Groote Eylandt was formed on a stable basement of Proterozoic quartzite that outcrops over the majority of the island.
The Proterozoic basement materials were eroded and redeposited under marine conditions during the early Cretaceous period.
A blanket of Cretaceous sediments was subsequently deposited over the basement and reworked basement materials in the west of the island. The distribution of Cretaceous sediments is generally confined to the western plains of the island. The upper Cretaceous sediments contain the manganese deposits.
The manganese ore is a sedimentary layer, consisting of manganese strata occurring between clay and sand beds. The ore body is essentially stratabound and strataform in character and it represents a continuous horizon up to 11 m thick. The ore body consists of pisolitic and oolitic manganese oxides.
Much of the Cretaceous sediment profile (including some of the manganese deposits) has been extensively modified by a long period of tropical weathering (or laterisation) during the Tertiary period. This has resulted in the development of thick laterite profiles up to 25m thick.
The laterite is strongly oxidised and leached and forms the iron and alumina rich layers above the manganese ore.
The typical stratigraphy of the project site is provided in Figure 3 and comprises (in reverse chronological order):
A thin veneer of Quaternary sediments;
A weathered profile of Tertiary laterite and lateritic clays;
Cretaceous marine clays including the manganese ore;
Cretaceous marine sandstone;
Cretaceous sandstone of reworked quartzite basement; and
the underlying Proterozoic quartzite basement.
The relative depth and thickness of each sedimentary unit varies across the Eastern Leases depending on the depth of the underlying Proterozoic basement.

3.0 METHODOLOGY The geochemical assessment of the project materials was guided by the requirements of the NT EPA Environmental Assessment Guideline on Acid and Metalliferous Drainage (AMD) (NT EPA, 2013). The geochemical assessment strategy was developed taking into account the key information sources, legislative requirements and methodology described in the Guideline.
3.1 Investigation Strategy RGS developed a site-specific investigation strategy to characterise the geochemistry of materials to be mined and processed as part of the project (RGS, 2013). The strategy was developed taking into account Australian (TEAM NT, 2004; DME, 1995; and DITR, 2006a,b; 2007a,b; 2008) and international (INAP, 2009) technical guidelines for the geochemical assessment of mine waste materials (NT EPA, 2013).
The strategy took into account the availability of detailed site-specific exploration and geological data,to allow the targeted collection of representative samples of ore and overburden from the lithological profile at the project site. In addition, the investigation layout was designed to provide sample distribution across the proposed mining areas. This combined approach allowed RGS to accurately characterise materials likely to be generated by the project.
The investigation strategy also involved review of existing geochemical data on slime and sand tailings materials and collection of middlings samples from the existing GEMCO operation to allow comparison with the results of the site-specific investigations.
3.2 Field Investigation and Sampling Program Based upon the available site-specific exploration and geological data, field investigations undertaken at the project site included:
Rotary coring and full core logging of six geochemistry bores; and
Open hole drilling and logging of drill chips from 19 groundwater monitoring bores and 4 groundwater production bores (located at a total of 10 sites).
All drill holes were logged and sampled by a suitably qualified geologist or hydrogeologist to ensure the collection of representative samples.
Following review of the drilling logs, samples were selected for detailed geochemical analysis. Samples were preferentially selected from geochemistry bores due to the high quality of the cored material. Additional samples of drill chip materials were collected from representative monitoring bores.
A total of 112 ore and overburden samples were selected, comprising 54 drill core samples and 58 drill chip samples. Four supplementary middlings samples were collected from the existing middlings storage at GEMCO operation on 6 June 2014.
The distribution of samples collected is shown on Figure 4. Table 1 provides the number of samples of each type of material collected and used in the geochemical assessment.
Drill chip and middlings samples typically comprised 1 to 2 kg of material stored in plastic sample bags. Drill core samples typically comprised full core taken from targeted drill core depth intervals no greater than 0.5 m. All samples were stored in a cool dry location until dispatch to Australian Laboratory Services in Brisbane (ALS Brisbane) for geochemical testing.

3.3 Geochemical Test Program The GEMCO samples received by ALS Brisbane were prepared by crushing (where necessary) and pulverising to ≤ 75 µm particle size. This standard laboratory procedure provides a homogenous sample but also generates a large sample surface area in contact with the resultant assay solution, thereby providing greater potential for dissolution and reaction, and represents an assumed initial ‘worst case’ scenario for these materials.
A series of static and kinetic geochemical tests were completed on the GEMCO samples. The geochemical test program was designed to assess the degree of risk from the presence and potential oxidation of sulfides, acid generation and the presence/leaching of soluble metals/metalloids and salts. The assessment also included characterisation of standard soil parameters including salinity, dispersion, cation exchange capacity, exchangeable sodium percentage, and major metal concentrations.
A summary of the parameters involved in geochemical assessment of ore and mine waste materials is provided in Attachment A.
3.3.1 Static Geochemical Tests
Static geochemical tests provide a ‘snapshot’ of the geochemical characteristics of a sample material at a single point in time. These tests were staged to screen a large number of samples before selecting either individual and/or composite samples for more detailed static test work.
The Acid Base Account (ABA) was used as a screening procedure whereby the acid-neutralising and acid-generating characteristics of a material are assessed. All 116 samples were screened using ABA. The ABA screening included static geochemical testing for the following parameters:
pH (1:5 w:v, sample:deionised water);
Electrical conductivity (EC) (1:5 w:v, sample:deionised water);
Total sulfur [Leco method]; and
Acid neutralising capacity (ANC) [AMIRA, 2002 method].
The results of the ABA screening assessment are discussed in Section 4.1. Where initial ABA screening results indicated that total sulfur content was greater than average crustal abundance (0.1%) (INAP, 2009), samples were selected for further sulfur speciation testing. A total of four samples were tested for chromium reducible sulfur (Scr) [AS 4969.7-2008 method].
From the total sulfur (or Scr where available) and ANC results, the maximum potential acidity (MPA) and net acid producing potential (NAPP) values of the sample materials were calculated. Where

A total of four samples were tested for chromium reducible sulfur (Scr) [AS 4969.7-2008 method].
From the total sulfur (or Scr where available) and ANC results, the maximum potential acidity (MPA) and net acid producing potential (NAPP) values of the sample materials were calculated. Where
Appendix A | Geochemistry Report

Page 6
available, the MPA and NAPP values were calculated using Scr data instead of total sulfur data. Scr data (for fresh samples) generally provides a more accurate representation of the MPA that could theoretically be generated, as acid generation primarily occurs from oxidation of reactive sulfides(eg. pyrite), whereas total sulfur includes other forms of sulfur such as sulfate and organic sulfur,which produce negligible acidity.
After the results of the ABA screening tests were received and interpreted, 18 drill core samples and four middlings samples were selected, prepared and subjected to multi-element analysis. The samples were selected based on material type, location, lithology and geochemical characteristics. All selected samples underwent multi-element testing on both the solid and soluble fractions. The 22selected samples were tested for: Total alkalinity and acidity (automatic titrator measured as CaCO3);
Total metals/metalloids (Al, Ag, As, B, Ba, Be, Cd, Cr, Co, Cu, Fe, Hg, Pb, Mn, Mo, Ni, Sb, Se, Th, U, V and Zn) in solids [HCl and HNO3 acid digest followed by FIMS and/or ICP-AES/MS];
Total cations (Ca, Mg, Na and K) [HCl and HNO3 acid digest followed by ICP-AES/MS];
Soluble metals/metalloids (Al, Ag, As, B, Ba, Be, Cd, Cr, Co, Cu, Fe, Hg, Pb, Mn, Mo, Ni, Sb, Se, Th, U, V and Zn) [ICP-AES/MS and FIMS (1:5 w:v water extracts)];
Major cations (Ca, Mg, Na and K) [ICP-AES/MS (1:5 w:v water extracts)]; and
Major anions (Cl, F and SO4) [ICP-AES/MS and PC Titrator (1:5 w:v water extracts)].
A total of six samples were logged as containing a visual abundance of the clay minerals smectite and kaolinite. These samples included one sample from EL-N-GC02 (4.5-4.85m); three samples from EL-N-GC03 (8.6-9.0 m, 21.0-21.5 m and 22.65-22.8 m) and two samples from EL-S-GC04 (8.4-8.7 m and9.5 to 9.8 m). As these samples were located in overburden (two samples) and interburden (four samples), and were visually distinct, these six samples were subjected to additional detailed testing to confirm the likely behaviour of these clays if disturbed by mining, including:
Exchangable Cations (Ca, Mg, Na, K) [by ICP-AES/MS];
Effective Cation Exchange Capacity (eCEC) and Exchangeable Sodium Percentage (ESP);
Particle Size Distribution (PSD) [hydrometer - AS1289.3.6.3]; and
Emerson Aggregate test.
The ALS test results for the static geochemical test program are provided in Attachment B. Summary results tables are provided in Attachment C and discussed in Sections 4 to 6.
3.3.2 Kinetic Geochemical Tests
Following receipt and interpretation of the static geochemical test results, six Kinetic Leach Column (KLC) tests were set up at the RGS in-house laboratory using crushed or ‘as received’ samples. The KLC tests comprised the most representative composite samples of overburden (four samples), ore (one sample) and middlings (one sample). The KLC tests commenced in August 2014 and operated under a monthly watering and leaching cycle for six months until February 2015. The KLC tests followed standard mining industry guidelines for such tests (AMIRA, 2002).
Approximately 1-2 kg of each selected sample was used in the KLC tests with the weight varying according to sample bulk density. Heat lamps were used on a daily basis to simulate sunshine and ensure that the KLC test materials were unsaturated and subject to oxidising conditions between leaching events. This method essentially represents the worst case or maximum potential for sulfide oxidation and potential acid/salt generation.

All leachate samples collected from the KLC tests were sent to ALS Brisbane for analysis of various parameters including:
pH and EC;
Acidity and alkalinity [Automatic titrator];
Dissolved metals/metalloids (Ag, Al, As, B, Ba, Be, Cd, Cr, Co, Cu, F, Fe, Hg, Pb, Mn, Mo, Ni, Sb, Se, Th, U, V and Zn) [ICP-AES and FIMS];

4.0 OVERBURDEN GEOCHEMISTRY
4.1 Acid Base Account Results The ABA results for the 86 overburden samples are provided in Table C-1 (Attachment C). For the purposes of this discussion, the term overburden has been used to refer to both overburden and interburden samples. An explanation of the methodology used in this section, including a description of the ABA screening method, is provided at Section 3.3 and a glossary of terms and acronyms used is listed on Page IV. The ABA data trends discussed in this section are presented in Graphs 1 to 5.
pH: The natural pH of the deionised water used in the pH tests is typically in the pH range 5.0 to 6.5. The pH(1:5) of the 86 overburden samples ranges from pH 3.4 to 8.9 and has a neutral median pH value of 6.0 (Graph 1). The majority of the samples (92 %) have pH values within the range pH 5.0 to 7.0. Four overburden samples have a pH value greater than pH 7.0 indicating the presence of some alkalinity. Three overburden samples have pH values less than pH 5.0 indicating the presence of some acidity. The three samples with reduced pH values represent clay (drill chip) overburden material sampled from drill hole EL-S-MB06 (18m, 21m and 24m depth) located at the north-west of the Southern Eastern Lease. There is no other correlation between sample pH and sample location, depth, type or lithology.
Electrical Conductivity (EC): The current EC(1:5) of the 86 overburden samples ranges from 6 to 2,740 µS/cm and is typically low, (median 36 µS/cm). Two overburden samples have an EC value greater than 1,000 µS/cm (Graph 2) and represent clay (drill chip) overburden material sampled from drill hole EL-S-MB06 at 18m and 21m depth. There is no other correlation between sample EC and sample location, depth, type or lithology.
Geochemistry Report: Eastern Leases Project

Total Sulfur: The total sulfur content of the 86 overburden samples range from 0.005 percent sulfur (%S) to 0.87 %S and is typically low (median 0.02 %S) compared to average crustal abundance (0.1 %) for this element (INAP, 2009). Materials with a total sulfur content less than or equal to 0.1 %S are essentially barren of sulfur, generally represent background concentrations, and have negligible capacity to generate acidity1. Three of the 86 overburden samples tested (3.5 %) had total sulfur values greater than 0.1 %S. These samples represent overburden from bores EL-S-MBO5 (36 m) and EL-S-MB06 (18 m and 21 m).
Sulfide Sulfur: Scr analysis was undertaken on the three overburden samples with total sulfur values greater than 0.1 %S to confirm their sulfide sulfur content. One of the three samples (EL-S-MB-06 (18 m)) had a sulfide sulfur value significantly less than the total sulfur value,indicating that much of the sulfur is likely to be present as other forms of sulfur such as organic sulfur and sulfate which, in comparison to a reactive sulfur form such as pyrite, has negligible capacity to generate acidity if exposed to oxidising conditions. The remaining two samples have sulfide sulfur values similar to total sulfur values indicating that most of the sulfur is likely to be present as reactive sulfur (eg. pyrite).
Graph 3 shows the sulfur content of the overburden materials2 and illustrates that these materials typically have very low sulfide sulfur content, with 83 of the 86 samples (96.5 %) having sulfide sulfur content less than 0.1 %S.
Maximum Potential Acidity (MPA): The MPA for the overburden samples ranges from 0.2 to 19.2 kg H2SO4/t, and is typically very low with a median value of 0.6 kg H2SO4/t.
Acid Neutralising Capacity (ANC): The ANC value for the overburden samples ranges from 0.25 to 8.4 kg H2SO4/t and has a median value of 1.4 kg H2SO4/t (more than double the median MPA).
Net Acid Producing Potential (NAPP): The NAPP is the balance between the capacity of a sample to generate acidity (MPA) minus its capacity to neutralise acidity (ANC). The calculated NAPP value for the samples ranges from -7.8 to +18.6 kg H2SO4/t and has a negative median value of -0.8 kg H2SO4/t. The NAPP data for the overburden samples are presented in Graph 4and illustrate that the vast majority of overburden samples have NAPP values that are negative or close to zero.
Given the typically low sulfide sulfur content of these materials, the risk of generating any significant acidity and/or neutral mine drainage (NMD) from bulk overburden materials is
1 The average crustal abundance of sulfur is approximately 0.1 % (INAP, 2009). 2 The total sulfur content of the samples was used in the graph when no sulfide sulfur data was available.

4.0 OVERBURDEN GEOCHEMISTRY
4.1 Acid Base Account Results The ABA results for the 86 overburden samples are provided in Table C-1 (Attachment C). For the purposes of this discussion, the term overburden has been used to refer to both overburden and interburden samples. An explanation of the methodology used in this section, including a description of the ABA screening method, is provided at Section 3.3 and a glossary of terms and acronyms used is listed on Page IV. The ABA data trends discussed in this section are presented in Graphs 1 to 5.
pH: The natural pH of the deionised water used in the pH tests is typically in the pH range 5.0 to 6.5. The pH(1:5) of the 86 overburden samples ranges from pH 3.4 to 8.9 and has a neutral median pH value of 6.0 (Graph 1). The majority of the samples (92 %) have pH values within the range pH 5.0 to 7.0. Four overburden samples have a pH value greater than pH 7.0 indicating the presence of some alkalinity. Three overburden samples have pH values less than pH 5.0 indicating the presence of some acidity. The three samples with reduced pH values represent clay (drill chip) overburden material sampled from drill hole EL-S-MB06 (18m, 21m and 24m depth) located at the north-west of the Southern Eastern Lease. There is no other correlation between sample pH and sample location, depth, type or lithology.
Electrical Conductivity (EC): The current EC(1:5) of the 86 overburden samples ranges from 6 to 2,740 µS/cm and is typically low, (median 36 µS/cm). Two overburden samples have an EC value greater than 1,000 µS/cm (Graph 2) and represent clay (drill chip) overburden material sampled from drill hole EL-S-MB06 at 18m and 21m depth. There is no other correlation between sample EC and sample location, depth, type or lithology.

Sulfide Sulfur: Scr analysis was undertaken on the three overburden samples with total sulfur values greater than 0.1 %S to confirm their sulfide sulfur content. One of the three samples (EL-S-MB-06 (18 m)) had a sulfide sulfur value significantly less than the total sulfur value,indicating that much of the sulfur is likely to be present as other forms of sulfur such as organic sulfur and sulfate which, in comparison to a reactive sulfur form such as pyrite, has negligible capacity to generate acidity if exposed to oxidising conditions. The remaining two samples have sulfide sulfur values similar to total sulfur values indicating that most of the sulfur is likely to be present as reactive sulfur (eg. pyrite).
Graph 3 shows the sulfur content of the overburden materials2 and illustrates that these materials typically have very low sulfide sulfur content, with 83 of the 86 samples (96.5 %) having sulfide sulfur content less than 0.1 %S.
Maximum Potential Acidity (MPA): The MPA for the overburden samples ranges from 0.2 to 19.2 kg H2SO4/t, and is typically very low with a median value of 0.6 kg H2SO4/t.
Acid Neutralising Capacity (ANC): The ANC value for the overburden samples ranges from 0.25 to 8.4 kg H2SO4/t and has a median value of 1.4 kg H2SO4/t (more than double the median MPA).
Net Acid Producing Potential (NAPP): The NAPP is the balance between the capacity of a sample to generate acidity (MPA) minus its capacity to neutralise acidity (ANC). The calculated NAPP value for the samples ranges from -7.8 to +18.6 kg H2SO4/t and has a negative median value of -0.8 kg H2SO4/t. The NAPP data for the overburden samples are presented in Graph 4and illustrate that the vast majority of overburden samples have NAPP values that are negative or close to zero.
Given the typically low sulfide sulfur content of these materials, the risk of generating any significant acidity and/or neutral mine drainage (NMD) from bulk overburden materials is
1 The average crustal abundance of sulfur is approximately 0.1 % (INAP, 2009). 2 The total sulfur content of the samples was used in the graph when no sulfide sulfur data was available.

The three samples were all sourced from two drill holes (EL-S-MB05 and EL-S-MB06) located at the north-west end of the Southern Eastern Lease and correspond to the 3 samples which had sulfide sulfur values >0.1%.
ANC:MPA ratio: The ANC:MPA ratio of the overburden samples ranges from 0.03 to 26.1 and is typically elevated (median 2.5). In simplistic terms, this means that the ANC is greater than double the small amount of MPA that could theoretically be generated from the overburden samples.
Graph 5 shows a plot of ANC versus MPA for the overburden samples. ANC:MPA ratio lines have been plotted on the graph to illustrate the factor of safety associated with the samples, in terms of potential for generation of AMD. Generally those samples with an ANC:MPA ratio of greater than 2 and a sulfide sulfur content of <0.1% are considered to represent material with a low to negligible risk of acid generation and a high factor of safety in terms of potential for AMD (DITR, 2007; INAP, 2009).The majority of the samples fall within the negligible and low risk domains in the graph and therefore have a high factor of safety and very low risk of acid generation.

Three of the overburden samples fall in the ‘increased risk’ domain and represent clay overburden materials sampled from two drill holes (EL-S-MB05-D and EL-S-MB06-D) located at the north-west end of the Southern Eastern Lease. These samples correspond to those samples that reported sulfide sulfur >0.1% and elevated NAPP.
The ABA test data presented in Table C-1 (Attachment C) and discussed in this section has been used to classify the acid forming nature of the overburden materials. These classification criteria generally reflect Australian (DITR, 2007) and international (INAP, 2009) guideline criteria for classification of mine waste materials. Table 2 provides a summary of the criteria used by RGS to classify the acid forming nature of the samples and a breakdown of the number of samples in each classification category by material type.
The data presented in Table 2 illustrate that 83 of the 86 overburden samples (96.5%) are classified as Non-Acid Forming-Barren (NAF-Barren) and only 3.5 % are classified as Potentially Acid Forming (PAF). The three samples classified as PAF were all sourced from below 18 m depth at two drill holes (EL-S-MB05 and EL-S-MB06) located at the north-west end of the Southern Eastern Lease.

Samples that fall outside the stated NAF-Barren/PAF classification categories based on the criteria provided are classified as Uncertain.
4.2 Multi-Element Concentration in Solids Multi-element scans were carried out on 16 selected samples of overburden to identify any elements (metals/metalloids) present in these materials at concentrations that may be of environmental concern with respect to materials handling, storage, and water quality. The results were compared to potentially relevant guideline criteria to determine any concerns related to mine operation and final rehabilitation. To provide relevant context, RGS has compared the total metal/metalloid concentration in samples to National Environmental Protection Council (NEPC) Health-based Investigation Levels (HIL(C)) for soils in public open spaces (NEPC, 2013).
The 16 samples of overburden materials used in the multi-element test work are described in Table C-2 (Attachment C). The results from multi-element testing (total metals/metalloids) of the samples are presented in Table C-3 (Attachment C). The results indicate that the overburden materials typically have low total metal and metalloid concentrations in solids, many below the laboratory limit of reporting (LoR) and all below the applied NEPC (HIL(C)) guideline for soils. The only exception is the elevated concentration of manganese, which exceeds the NEPC (HIL(C)) guideline in 11 of 16 samples. This is expected given that these samples were taken from in and around a manganese deposit.

4.3 Dispersion and Erosion 4.3.1 Sodicity
The exchangeable sodium percentage (ESP) results for 16 overburden samples described in Section 4.2 are presented in Table C-3 (Attachment C).
The ESP results for the composite overburden samples range from <0.1 to 3.5 % and have a median value of 1.8 %. Generally samples with ESP values less than 6 are considered non-sodic and unlikely to be susceptible to dispersion and erosion (Isbell, 2002; and Northcote and Skene, 1972).
Overall, the results of the eCEC and ESP tests indicate that the overburden materials are likely to be non-sodic, and are consequently unlikely to be susceptible to dispersion and erosion.
4.3.2 Ultrafine Clays
As described in Section 3.3.1, smectite and kaolinite clay minerals occur within some of the overburden and interburden materials at the Eastern Leases and are generally ultrafine-grained (normally considered to be less than 2 µm in size in standard particle size classification systems).
The results of Particle Size Distribution (PSD) and Emerson Aggregate (EA) tests on these materials are summarised in Table C-4 (Attachment C).
The PSD results indicate that the composition of the six overburden samples selected for testing is between 9 % and 45 % clay minerals, with the remainder comprising silt, sand and gravel.
The EA test results indicate that the six overburden samples are characterised as either slaking but non-dispersive (Class 4) or non-slaking and non-dispersive (Class 8).
Overall, the PSD and EA results suggest that materials represented by the six overburden samples generally contain a smaller proportion of clay minerals compared to their combined silt, sand and gravel fraction and are classified as non-dispersive.
4.4 Water Quality Static Leach Tests RGS has compared the multi-element results in water extracts from the 16 overburden samples described in Section 4.2 with ANZECC & ARMCANZ (2000) guideline values. These guidelines are provided for context only and are not intended to be interpreted as “maximum permissible levels” for site water storage or discharge. Site-specific water quality criteria are described in detail in the EIS Surface Water Section.
It should also be recognised that direct comparison of geochemical data with guideline values can bemisleading. For the purpose of this study, guideline values are only provided for broad context and should not be interpreted as arbitrary ‘maximum’ values or ‘trigger’ values. Using sample pulps (ground to passing 75 µm) provides a very high surface area to solution ratio, which encourages mineral reaction and dissolution of the solid phase. As such, the results of screening tests on water extract solutions are assumed to represent an assumed ‘worst case’ scenario for initial surface runoff and seepage from overburden materials.
The results from multi-element testing of water extracts (1:5 solid:water) from the 16 overburden samples are presented in Table C-5 (Attachment C).
The pH of the water extracts ranges from pH 4.9 to 6.2 (median 5.7) and is typically within the pH range of the deionised water used in the water extract tests (ie. pH 5.0 to 6.5). This indicates that these materials are unlikely to contribute any acidity to initial surface runoff and seepage.
This is further supported by the typically low acidity of the water extracts, which ranges from 3 to 14 mg/L (median 5 mg/L). The alkalinity of the water extracts spans the same range (3 to 14 mg/L) (median 6 mg/L), and is typically equivalent to the measured acidity.
Geochemistry Report: Eastern Leases Project
Page 13
The EC in the water extracts is typically very low, ranging from 8 to 36 µS/cm (median 17 µS/cm).This confirms that these materials exhibit low salinity and low concentrations of dissolved solids when in contact with water. The concentrations of the major cations and anions in the water extracts are typically very low and below the LoR.
The concentration of all trace metals/metalloids tested in the water extracts is below the laboratory LoR in all samples. The only exception is manganese, which is above the LoR in most samples. However, the maximum and median values of 0.254 mg/L and 0.007 mg/L are well below the guideline value of 1.90 mg/L for protection of freshwater ecosystems.
The results indicate that dissolved metal/metalloid concentrations in initial surface runoff and seepage from permanent overburden emplacements are unlikely to impact upon the quality of surface and groundwater resources at relevant storage facilities.
4.5 Water Quality Kinetic Leach Tests As described in Section 3.3.2 and Attachment A, KLC tests were undertaken for four composite samples of overburden from the project site (i.e. KLC 1 to KLC 4). The composite KLC samples comprised three samples (KLC2, KLC3 and KLC4) that are representative of the NAF materials that comprise the vast majority of the overburden that will be generated by the project. A composite KLC sample (KLC1) was also selected to further investigate the characteristics of the small proportion of the potential overburden material that was identified as PAF from static testing.
The KLC test results are presented in Attachment D and interpreted in this section. The compositions of the four composite samples used in the KLC tests are provided in Table C-9 (Attachment C). The static ABA test results for the individual samples used to make up the four composite KLC samples are detailed in Table C-10 (Attachment C).
The KLC leachate concentrations are presented alongside ANZECC & ARMCANZ (2000) guideline values. These guidelines are provided for context only and are not intended to be interpreted as “maximum permissible levels” for site water storage or discharge. It should be noted that the ratio of sample to water in most of the KLC tests is typically 2:1 (w/v) (i.e. concentrated), whereas the ratio of sample to water generally used in tests where results can (arbitrarily) be compared against guideline concentrations to provide relevant context is an order of magnitude more dilute at 1:5 (w/v). Whilst arbitrary comparisons against guideline concentrations can be useful in some situations and help to provide relevant context, such comparisons cannot be directly extrapolated to the field situation at the project.
5.4.1 Bulk Overburden Leachate
The KLC leachate pH trends show that the leachate pH from the three NAF overburden samples is fairly consistent over the six month test period and remains within the pH range 5.3 to 7.3. Dynamic contact with overburden typically adds very little acidity or alkalinity to the deionised water used in the KLC tests (the typical pH of the deionised water used in the tests is in the pH range 5 to 6.5).
The EC value of KLC leachate from the overburden samples is typically low and ranges from 12 to 99 µS/cm. The EC generally shows a steady or decreasing trend over the test period. After the initial leaching event, the EC of KLC leachate remains below 50 µS/cm, even under ideal oxidising (wetting and drying) conditions.
The concentration of sulfate in leachate from the KLC tests has been used to calculate the residual sulfur content of the overburden materials. The results show that at least 97.8 % of the total sulfur content remains in the NAF samples. For these samples, the sulfate concentration in KLC leachate is generally two orders of magnitude lower than the applied guideline value (ANZECC & ARMCANZ, 2000).
The concentrations of dissolved calcium and magnesium in leachate from the KLC tests have been used to calculate the residual ANC remaining in the overburden materials. The results indicate that for

The static ABA test results for the individual samples used to make up the four composite KLC samples are detailed in Table C-10 (Attachment C).
The KLC leachate concentrations are presented alongside ANZECC & ARMCANZ (2000) guideline values. These guidelines are provided for context only and are not intended to be interpreted as “maximum permissible levels” for site water storage or discharge. It should be noted that the ratio of sample to water in most of the KLC tests is typically 2:1 (w/v) (i.e. concentrated), whereas the ratio of sample to water generally used in tests where results can (arbitrarily) be compared against guideline concentrations to provide relevant context is an order of magnitude more dilute at 1:5 (w/v). Whilst arbitrary comparisons against guideline concentrations can be useful in some situations and help to provide relevant context, such comparisons cannot be directly extrapolated to the field situation at the project.
5.4.1 Bulk Overburden Leachate
The KLC leachate pH trends show that the leachate pH from the three NAF overburden samples is fairly consistent over the six month test period and remains within the pH range 5.3 to 7.3. Dynamic contact with overburden typically adds very little acidity or alkalinity to the deionised water used in the KLC tests (the typical pH of the deionised water used in the tests is in the pH range 5 to 6.5).
The EC value of KLC leachate from the overburden samples is typically low and ranges from 12 to 99 µS/cm. The EC generally shows a steady or decreasing trend over the test period. After the initial leaching event, the EC of KLC leachate remains below 50 µS/cm, even under ideal oxidising (wetting and drying) conditions.
The concentration of sulfate in leachate from the KLC tests has been used to calculate the residual sulfur content of the overburden materials. The results show that at least 97.8 % of the total sulfur content remains in the NAF samples. For these samples, the sulfate concentration in KLC leachate is generally two orders of magnitude lower than the applied guideline value (ANZECC & ARMCANZ, 2000).
The concentrations of dissolved calcium and magnesium in leachate from the KLC tests have been used to calculate the residual ANC remaining in the overburden materials. The results indicate that for
Appendix A | Geochemistry Report

Page 14
the NAF samples, at least 99.2 % of the measured ANC remains in the samples at the end of the test period.
The sulfate generation rate results obtained for the four KLC tests on overburden have been used to determine the rate of sulfide oxidation in these materials. Most sulfate salts generated from sulfide reaction involving materials with a relatively low sulfide sulfur concentration are highly soluble, and therefore will be collected in column leachate. The dissolved sulfate (and calcium) concentrations in the KLC leachate are typically less than the solubility limit of gypsum (CaSO4), which indicates that sulfate generation is not controlled by gypsum dissolution in the KLC test materials. Therefore, the sulfate concentrations and oxidation rate calculations provide reasonable estimates of these parameters and the results align well with existing static and dynamic geochemical data derived from a wide range of mine waste materials (AMIRA, 1995). The sulfate generation rate and associated sulfide oxidation rate for the four KLC tests are shown in Table 3.
Table 3: Sulfate Generation and Sulfide Oxidation Rates for KLC Tests on Overburden
KLC Sample No. Sample Description Sulfate Generation Rate
(mg/kg/week)Oxidation Rate
(kg O2/m3/s)
KLC 1 PAF Overburden 302.3 1.2 x 10-7
KLC 2 NAF Overburden 0.3 1.3 x 10-10
KLC 3 NAF Overburden 0.1 4.1 x 10-11
KLC 4 NAF Overburden 0.2 7.3 x 10-11
The concentration of dissolved sulfate in leachate from the NAF samples is relatively consistent and tends towards a long term equilibrium value. The sulfate generation rate from the NAF overburden KLC samples ranges from 0.1 to 0.3 mg/kg/week indicating that the rate of sulfide oxidation is low in these materials (equivalent to an oxidation rate ranging from 4.1 x 10-11 to 1.3 x 10-10 kg O2/m3/s). Mine materials with an oxidation rate in this range have an increased factor of safety, and are likely to generate leachate that is pH neutral and/or has low levels of acidity (AMIRA, 1995; Bennett et al., 2000). Hence, all of the NAF overburden samples fall into this category and the KLC results reflect the NAF material characteristics predicted from static geochemical test results presented in Section 4.1.
The concentration of dissolved trace metals/metalloids in leachate from the four KLC tests on NAF overburden materials is typically very low, below the laboratory LoR, and within applied water quality guidelines. The only exception is manganese, which is above the LoR in the leachate samples with maximum and median values of 0.157 mg/L and 0.014 mg/L, respectively. These values are below the default water quality guideline value of 1.9 mg/L for protection of freshwater ecosystems.
Overall, these results indicate that dissolved metal/metalloid concentrations in ongoing surface runoff and seepage from the bulk overburden materials at emplacement areas are unlikely to significantly impact upon the quality of surface and groundwater resources.

As expected, the KLC leachate from the single PAF overburden sample (KLC1) has an acidic pH value, which remains within the range pH 4.9 to 2.3 and shows a decreasing trend from week 13 of the test period. This sample initially generates low EC leachate (109 µS/cm), but shows an increasing trend over the test period towards a final EC of approximately 7,000 µS/cm.
Approximately 60 % of the total sulfur content remains in the PAF sample at the end of the six month test period and the sulfate concentration in this leachate is also elevated towards the end of the test

period, as the ANC is consumed. However, the high residual ANC (99%) of the bulk overburden materials is likely to offset the depleted ANC exhibited by localised PAF material.
Nonetheless, the rates of sulfate generation and sulfide oxidation (Table 4) are greater than the bulk overburden and indicate that the localised PAF overburden material has a reduced factor of safety (AMIRA, 1995; Bennett et al., 2000). Management measures for handling and placing the small amount of PAF materials at overburden emplacement areas are provided at Section 4.6.
The concentration of dissolved trace metals/metalloids in this leachate shows a slight increase in metal concentrations (for aluminium, cobalt, copper, nickel and selenium) over the test period. While this indicates that localised PAF overburden materials have some potential to leach trace metals/metalloids into contact water with prolonged exposure to ideal oxidising (wetting and drying) conditions, management measures are proposed for handling and placing the small amount of PAF materials to ensure that these conditions are mitigated (Section 4.6).
4.6 Management Measures The interburden materials were found to be geochemically stable and no specific management measures are required to manage dispersion or erosion.
The bulk overburden materials were also geochemically stable, with no special management measures are required for the handling or storage of the majority of these materials.
However, there will be specific management measures for the handling and placing of overburden from the small area in the Southern Eastern Lease, which has been identified as containing PAF material. Management measures for this area include:
Undertaking geochemical sampling ahead of mining in areas located within 500 m of EL-S-MB06 and EL-S-MB05 in order to identify any PAF material;
Selectively handling and burying any PAF material within the centre of overburden emplacement areas away from final outer surfaces. PAF material will be placed directly within in-pit overburden emplacements, and will not be stored within temporary overburden emplacements.
In addition, samples will be collected at random from overburden emplacements and analysed on-site using net acid generation (NAG) tests as a rapid screening tool.
Surface water and seepage from overburden emplacement areas will be monitored to ensure that key water quality parameters remain within appropriate criteria. The proponent will:
Monitor surface run-off and seepage from the proposed overburden emplacement areas for pH, EC, total suspended solids (TSS) and the range of dissolved trace metals/metalloids and major ions including manganese on a quarterly basis; and
Undertake groundwater monitoring in accordance with the program described in the EIS Groundwater Report.

the NAF samples, at least 99.2 % of the measured ANC remains in the samples at the end of the test period.
The sulfate generation rate results obtained for the four KLC tests on overburden have been used to determine the rate of sulfide oxidation in these materials. Most sulfate salts generated from sulfide reaction involving materials with a relatively low sulfide sulfur concentration are highly soluble, and therefore will be collected in column leachate. The dissolved sulfate (and calcium) concentrations in the KLC leachate are typically less than the solubility limit of gypsum (CaSO4), which indicates that sulfate generation is not controlled by gypsum dissolution in the KLC test materials. Therefore, the sulfate concentrations and oxidation rate calculations provide reasonable estimates of these parameters and the results align well with existing static and dynamic geochemical data derived from a wide range of mine waste materials (AMIRA, 1995). The sulfate generation rate and associated sulfide oxidation rate for the four KLC tests are shown in Table 3.
Table 3: Sulfate Generation and Sulfide Oxidation Rates for KLC Tests on Overburden
KLC Sample No. Sample Description Sulfate Generation Rate
(mg/kg/week)Oxidation Rate
(kg O2/m3/s)
KLC 1 PAF Overburden 302.3 1.2 x 10-7
KLC 2 NAF Overburden 0.3 1.3 x 10-10
KLC 3 NAF Overburden 0.1 4.1 x 10-11
KLC 4 NAF Overburden 0.2 7.3 x 10-11
The concentration of dissolved sulfate in leachate from the NAF samples is relatively consistent and tends towards a long term equilibrium value. The sulfate generation rate from the NAF overburden KLC samples ranges from 0.1 to 0.3 mg/kg/week indicating that the rate of sulfide oxidation is low in these materials (equivalent to an oxidation rate ranging from 4.1 x 10-11 to 1.3 x 10-10 kg O2/m3/s). Mine materials with an oxidation rate in this range have an increased factor of safety, and are likely to generate leachate that is pH neutral and/or has low levels of acidity (AMIRA, 1995; Bennett et al., 2000). Hence, all of the NAF overburden samples fall into this category and the KLC results reflect the NAF material characteristics predicted from static geochemical test results presented in Section 4.1.
The concentration of dissolved trace metals/metalloids in leachate from the four KLC tests on NAF overburden materials is typically very low, below the laboratory LoR, and within applied water quality guidelines. The only exception is manganese, which is above the LoR in the leachate samples with maximum and median values of 0.157 mg/L and 0.014 mg/L, respectively. These values are below the default water quality guideline value of 1.9 mg/L for protection of freshwater ecosystems.
Overall, these results indicate that dissolved metal/metalloid concentrations in ongoing surface runoff and seepage from the bulk overburden materials at emplacement areas are unlikely to significantly impact upon the quality of surface and groundwater resources.

5.0 ORE GEOCHEMISTRY
5.1 Acid Base Account Results The ABA results for the 26 ore samples are provided in Table C-1 (Attachment C). The ABA data trends for ore are discussed in this section and presented in Graphs 6 to 10.
pH: The natural pH of the deionised water used in the pH tests is typically in the pH range 5.0 to 6.5. The pH(1:5) of the 26 ore samples ranges from pH 5.2 to 7.2 and has a neutral median pH value of 6.1 (Graph 6).
EC: The current EC(1:5) of the 26 ore samples ranges from 8 to 209 µS/cm and is typically low, (median 26 µS/cm) (Graph 7).
Total Sulfur: The total sulfur content of the 26 ore samples ranges from 0.005 %S to 0.31 %S and is typically low (median 0.02 %S) compared to background levels (0.1 %) for this element (INAP, 2009).
Sulfide Sulfur: Scr analysis was undertaken on the single ore sample (EL-S-MB05 (39 m))with a total sulfur value greater than 0.1 %S to confirm its sulfide sulfur content. The ore sample had a sulfide sulfur value of <0.1%. This is significantly less than the total sulfur value,indicating that much of the sulfur is likely to be present as other forms of sulfur such as organic sulfur and sulfate which, in comparison to a reactive sulfur form such as pyrite, has negligible capacity to generate acidity if exposed to oxidising conditions.

Graph 8 shows the sulfide sulfur content of the ore samples and illustrates that these materials typically have very low sulfide sulfur content, and all samples have a sulfide sulfur content less than or equal to 0.1 %S.
Maximum Potential Acidity (MPA): The MPA for the ore samples ranges from 0.2 to 2.9 kg H2SO4/t, and is typically very low with a median value of 0.6 kg H2SO4/t.
Acid Neutralising Capacity (ANC): The ANC value for the ore samples ranges from 0.25 to 7.6 kg H2SO4/t and has a median value of 2 kg H2SO4/t (i.e. more than three times the median MPA).
Net Acid Producing Potential (NAPP): The calculated NAPP value for the ore samples ranges from -6.7 to +0.4 kg H2SO4/t and has a negative median value of -1.4 kg H2SO4/t. The NAPP data for the ore samples are presented in Graph 9 and illustrate that all ore samples have NAPP values that are negative or close to zero.
Given the uniformly low sulfide sulfur content of these samples, the risk of generating any significant acidity and/or neutral mine drainage (NMD) from bulk ore materials is negligible.
ANC:MPA ratio: The ANC:MPA ratio of the ore samples ranges from 0.4 to 31.3 and is typically elevated (median 3.2). In simplistic terms, this means that the ANC is more than three times the small amount of MPA that could theoretically be generated from the ore samples.

The pH of the water extracts from the two ore samples is pH 5.0 and 5.8 and is therefore within the pH range of the deionised water used in the water extract tests (ie. pH 5.0 to 6.5). This indicates that these materials are unlikely to contribute any acidity to initial surface runoff and seepage.
This is further supported by the typically low acidity of the water extracts from the two samples (ie. 6 and 8 mg/L. The alkalinity of the water extracts from the two samples has a similar low value (3 and 7 mg/L), which is essentially equivalent to the measured acidity.
The EC in the water extracts from the two ore samples is very low (11 and 15 µS/cm). This confirms that these materials exhibit low salinity and low concentrations of dissolved solids when in contact with water. The concentrations of the major cations and anions in the two water extracts are typically very low and below the LoR.
The concentration of all trace metals/metalloids tested in the water extracts is below the laboratory LoR in all samples. The only exception is manganese, which is above the LoR in most samples. However, the maximum value of 0.014 mg/L is well below the guideline value of 1.90 mg/L for protection of freshwater ecosystems.
The results indicate that dissolved metal/metalloid concentrations in initial surface runoff and seepage from stockpiled run-of-mine ore materials are unlikely to impact upon the quality of surface and groundwater resources at relevant storage facilities.
5.4 Water Quality Kinetic Leach Tests As described in Section 3.2.2 and Attachment A, a KLC test was undertaken on a representative composite sample of ore from the project site. The composition of the composite sample used in the KLC test is listed in Table C-9 (Attachment C). The static ABA test results for the individual samples used to make up the composite KLC ore sample are detailed in Table C-10 (Attachment C). The KLC results are presented in Attachment D and interpreted in this section.
The KLC leachate pH trends for the ore sample in Attachment D show that the leachate pH from the sample (KLC5) is fairly consistent over the six month test period and trends from a pH of 6.7 towards a pH of 4.9. Dynamic contact with NAF ore typically adds very little acidity or alkalinity to the deionised water used in the KLC tests.
The EC value of KCL leachate from the ore sample is low and ranges from 17 to 31 µS/cm. The EC generally shows a slight decreasing trend over the test period.
The concentration of dissolved sulfate in leachate shows that at least 99 % of the total sulfur content remains in the ore at the end of the test period. The sulfate concentration in ore leachate is three orders of magnitude lower than the applied guideline value. At least 99 % of the measured ANC remains in the sample material at the end of the test period.
The concentration of dissolved sulfate in ore leachate is very low, relatively consistent, and tends towards a long term equilibrium value. The sulfate generation rate and associated sulfide oxidation rate for the KLC test on ore are shown in Table 4.

Graph 10 shows a plot of ANC versus MPA for the ore samples. ANC:MPA ratio lines have been plotted on the graph to illustrate the factor of safety associated with the samples, in terms of potential for generation of AMD. All of the samples fall within the negligible and low risk domains in the graph or have a negligible MPA content; and therefore have a high factor of safety and very low risk of acid generation.
The geochemical classification criteria previously presented in Table 2 highlights that all of the ore samples are classified as NAF-Barren.
5.2 Multi-Element Concentration in Solids Multi-element scans were carried out on two selected samples of ore to identify any elements (metals/metalloids) present in these materials at concentrations that may be of environmental concern with respect to materials handling, storage, and water quality. The ore samples used in the multi-element test work are described in Table C-2 (Attachment C). The results from multi-element testing (total metals/metalloids) of the samples are presented in Table C-3 (Attachment C).
The results indicate that the ore materials typically have low total metal and metalloid concentrations in solids, many below the LoR and all below the applied NEPC (HIL(C)) guideline for soils. The only exception is the elevated concentration of manganese, which exceeds the NEPC (HIL(C)) guideline in both samples. This is expected given that these samples were taken from within a manganese deposit.

leachate that is pH neutral and/or has a low level of acidity. Hence, the kinetic ore leachate results reflect the characteristics predicted from static geochemical test results presented in Section 5.1.
The concentration of dissolved trace metals/metalloids in leachate from the KLC test on the ore sample is typically very low, below the laboratory LoR, and within applied water quality guidelines. The only exception is naturally occurring manganese, which is above the LoR in the leachate samples,but with maximum and median values of 0.297 mg/L and 0.227 mg/L remains well below the guideline value of 1.9 mg/L for protection of freshwater ecosystems.
Overall, these results indicate that ongoing surface runoff and seepage from ore materials are unlikely to significantly impact upon the quality of surface water and groundwater. In addition, these materials are only stockpiled for a relatively short period of time and have limited interaction with contact water.
5.5 Management MeasuresThe geochemistry of the material does not indicate the need for any special management measures for the handling or stockpiling of the ore.

6.1 Acid Base Account Results As described in Section 3, ABA and multi-element tests were completed on four representative samples of process residue (middlings) material from the project site.
The ABA results are presented in Table C-6 (Attachment C) and show that the middlings have pH values within the pH range typical of the deionised water used in the tests (ie. pH 5.0 to 6.5). This indicates that the middlings are unlikely to contribute any acidity to initial surface runoff and seepage.
The salinity of water extracts from the middlings materials is very low (EC varies from 18 to23 µS/cm). This confirms that these materials exhibit low salinity and low concentrations of dissolved solids when in contact with water.
The sample materials have a very low total sulfur concentration, well below background levels for this element (ie. below 0.1%S) (INAP, 2009), resulting in a low MPA value of 0.15 kg H2SO4/t. The ANC for the samples is also relatively low, but remains at least an order of magnitude greater than the MPA, resulting in a negative NAPP and a high ANC:MPA ratio (median of 19.25). On the basis of these results, the middlings samples are classified as NAF-Barren and have a high factor of safety with respect to potential for acid generation.
6.2 Multi-Element Concentration in Solids The multi-element results (metals/metalloids in solids) for the middlings are presented in Table C-7(Attachment C). The results indicate that the middlings have low total metal/metalloid concentrations in solids within the applied HIL(C) guideline criteria (NEPC, 2013), except for manganese. The elevated manganese concentration in the middlings is expected given that these samples are derived from processing manganese ore.
6.3 Water Quality Static Leach Tests The results from multi-element testing of water extracts (1:5 solid:water) from the middlings materials are presented in Table C-8 (Attachment C). The concentration of all trace metals/metalloids tested in the water extracts is below the laboratory LoR, with the exception of manganese. However, the maximum concentration of 0.04 mg/L remains well below the guideline value of 1.9 mg/L for protection of freshwater aquatic ecosystems.
The water extract results indicate that dissolved metal/metalloid concentrations in any surface runoff from middlings materials are unlikely to impact upon the quality of surface and groundwater resources at the project site.
6.4 Water Quality Kinetic Leach Tests As described in Section 3.2.2 and Attachment A, a KLC test was undertaken on a representative composite sample of middlings from the project site. The composition of the composite sample used in the KLC test is listed in Table C-9 (Attachment C). The static ABA test results for the individual samples used to make up the composite KLC middlings sample are detailed in Table C-10(Attachment C). The KLC results are presented in Attachment D and interpreted in this section.
The KLC leachate trends for the middlings sample in Attachment D show that pH is fairly consistent over the test period and ranges from pH 6.9 to 5.2. Dynamic contact with middlings typically adds very little acidity or alkalinity to the deionised water used in the KLC tests (the typical pH of the deionised water used in the tests is in the pH range 5 to 6.5).
The EC value of KLC leachate from the middlings sample is low and ranges from 13 to 41 µS/cm, with a slight decreasing trend over the test period.

leachate that is pH neutral and/or has a low level of acidity. Hence, the kinetic ore leachate results reflect the characteristics predicted from static geochemical test results presented in Section 5.1.
The concentration of dissolved trace metals/metalloids in leachate from the KLC test on the ore sample is typically very low, below the laboratory LoR, and within applied water quality guidelines. The only exception is naturally occurring manganese, which is above the LoR in the leachate samples,but with maximum and median values of 0.297 mg/L and 0.227 mg/L remains well below the guideline value of 1.9 mg/L for protection of freshwater ecosystems.
Overall, these results indicate that ongoing surface runoff and seepage from ore materials are unlikely to significantly impact upon the quality of surface water and groundwater. In addition, these materials are only stockpiled for a relatively short period of time and have limited interaction with contact water.
5.5 Management MeasuresThe geochemistry of the material does not indicate the need for any special management measures for the handling or stockpiling of the ore.

The residual sulfur content of this material shows that at least 99% of the total sulfur content remains in the sample at the end of the six month test period. The sulfate concentration in KLC middlings leachate is three orders of magnitude lower than the applied guideline value. The concentrations of dissolved calcium and magnesium in leachate indicate that at least 99% of the measured ANC remains in the sample material at the end of the test period.
The concentration of dissolved sulfate in middlings leachate is relatively consistent and tends towards a long term equilibrium value. The sulfate generation rate and associated sulfide oxidation rate for the KLC test on middlings are shown in Table 5.

The sulfate generation rate from the KLC test on the middlings sample is 0.03 mg/kg/week indicating that the rate of sulfide oxidation is low (equivalent to an oxidation rate of 1.1 x 10-11 kg O2/m3/s), with an increased factor of safety (AMIRA, 1995, Bennett et al., 2000). These materials are likely to generate leachate that is pH neutral and/or has a low level of acidity. Hence, the KLC results reflect the characteristics predicted from static geochemical test results presented in Section 6.1.

7.0 REVIEW OF TAILINGS GEOCHEMISTRY While the EIS does not include any assessment of operations within the existing GEMCO mine, a review of geochemical data available for tailings generated and stored at the existing operations has been included for completeness.
GEMCO has established handling and storage methods for process residues and these methods have been operating since the commencement of operations.
As previously discussed in Section 2.2, the ore lithology is relatively uniform across the west of the island. It is therefore likely that the tailings samples selected and tested at the existing GEMCO mine will provide a good representation of the geochemical properties of the range of tailings materials likely to be generated from the processing of ore from the Eastern Leases.
The proponent maintains a database of geochemical data on the geochemistry of the slime and sand tailings (GEMCO, 2014). These data have been reviewed by RGS and the main findings are summarised as follows:
The slime and sand tailings are classified as NAF on the basis of having negligible sulfur content and excess buffering capacity.
The slime and sand tailings typically have relatively low total metal/metalloid concentrations in solids which are within applied Health Based (HIL(C)) guideline criteria for recreational open spaces (NEPC, 2013), except for manganese. The elevated manganese concentration in these materials is expected given that the samples are derived from processing manganese ore.
Leachate from slime and sand materials is typically towards the lower end of the pH neutral range and also has a low salinity.
The concentration of most trace metals/metalloids in leachate from slime and sand tailings is low, typically below the laboratory limit of reporting, and less than the applied ANZECC & ARMCANZ (2000) trigger values for 95 % species protection.
This information confirms that from a geochemical perspective, the slime and sand tailings are relatively benign and very similar to the middlings materials. The geochemistry of the material does not indicate the need for any special management measures for the handling or storage of the tailings material.

8.0 CONCLUSIONS RGS has completed a geochemical assessment of overburden, ore and process residue materials likely to be generated by the project. The main findings of the geochemical assessment are presented in the following sections.
8.1 Overburden The overwhelming majority of overburden show excess acid buffering capacity, and a high
factor of safety with respect to potential acid generation.
The bulk excavated overburden material generated by the project will have a significant excess buffering capacity at least double the MPA and is therefore considered to be NAF.
Smectite and kaolinite clay minerals that may be sporadically present within the excavated overburden material are non-dispersive and should not provide a significant materials handling issue.
The concentrations of metals and metalloids in excavated overburden material are within relevant health-based criteria. Only manganese was found to be elevated, reflecting the natural geological setting of the project. During the project life, these materials will be handled and stored within operational mining areas and there will be negligible potential for human health impacts through contact with these materials. Mined areas will be progressively rehabilitated,further reducing potential manganese exposure pathways.
Surface runoff and seepage from excavated overburden material is likely to exhibit low acidity with excess buffering capacity. Salinity will be low due to a general absence of dissolved solids.
Static and kinetic leach tests indicate that trace metals/metalloids and major ions will be sparingly soluble in runoff and seepage from excavated overburden material. Dissolved concentrations will remain within applied water quality guideline criteria and will not present any significant environmental risks for on-site or downstream water quality. Dilution effects from rainfall and natural attenuation are also likely to occur in the field and further reduce the concentrations of soluble metals and metalloids in runoff and seepage.
Based on the benign nature of the overburden material, no special management measures are required for the handling or storage of the majority of the overburden. There will, however, be specific management measures for the handling and placing of overburden from the small area which has been identified as containing PAF material, and these measures are described in the report (as discussed in Section 4.6).
Surface water and seepage from overburden emplacement areas will be monitored to ensure that key water quality parameters remain within appropriate criteria. Groundwater monitoring will also be undertaken.
8.2 Ore The run of mine ore generated by the project has an excess buffering capacity, which is
significantly greater than the MPA, and is therefore considered to be NAF. Storage of run of mine ore generated by the project is therefore unlikely to generate acid.
The concentrations of metals and metalloids in run of mine ore are within relevant health-based criteria. Only manganese was found to be elevated, reflecting the natural geological setting of the project. During the project life, run of mine ore will be handled and stored within operational mining areas and there will be negligible potential for human health impacts through contact with these materials. No run of mine ore materials will remain on site following mine closure and rehabilitation.

The geochemistry of the Eastern Leases ore does not indicate the need for any special management measures for the handling or temporary storage of the run of mine ore materials.
8.3 Tailings and Middlings The tailings and middlings generated by the project have an excess buffering capacity, which is
significantly greater than the MPA, and are therefore considered to be NAF. Storage and reuse of tailings and middlings generated by the project is unlikely to generate acid.
The concentrations of metals and metalloids in tailings and middlings are within relevant health-based criteria. Only manganese was found to be elevated, reflecting the natural geological setting of the project. During the project life, these materials will be handled and stored within operational mining areas and there will be negligible potential for human health impacts through contact with these materials. As part of mine closure and rehabilitation activities, materials will be removed or capped, further reducing potential manganese exposure pathways.
Surface runoff and seepage from tailings and middlings are likely to exhibit low acidity with excess buffering capacity. Salinity will be low due to a general absence of dissolved solids.
Static and kinetic leach tests indicate that trace metals/metalloids and major ions are sparingly soluble in runoff and seepage from tailings and middlings.

GEOCHEMICAL ASSESSMENT OF MINE WASTE MATERIALS
ACID GENERATION AND PREDICTIONAcid generation is caused by the exposure of sulfide minerals, most commonly pyrite (FeS2), to atmospheric oxygen and water. Sulfur assay results are used to calculate the maximum amount of acid that could be generated by a material based on either direct measurement of the pyritic S content, or assuming that all sulfur not present as sulfate occurs as pyrite. Pyrite reacts under oxidising conditions to generate acid according to the following overall reaction:
FeS2 + 15/4 O2 + 7/2 H2O ---> Fe(OH)3 + 2 H2SO4
According to this reaction, the maximum potential acidity (MPA) of a sample containing 1%S as pyrite would be 30.6 kg H2SO4/t. The chemical components of the acid generation process consist of the above sulfide oxidation reaction and acid neutralization, which is mainly provided by inherent carbonates and to a lesser extent silicate materials. The amount and rate of acid generation is determined by the interaction and overall balance of the acid generation and neutralisation components.
Net Acid Producing Potential
The net acid producing potential (NAPP) is used as an indicator of materials that may be of concern with respect to acid generation. The NAPP calculation represents the balance between the maximum potential acidity (MPA) of a sample, which is derived from the sulfide sulfur content, and the acid neutralising capacity (ANC) of the material, which is determined experimentally. By convention, the NAPP result is expressed in units of kg H2SO4/t sample. If the capacity of the solids to neutralise acid (ANC) exceeds their capacity to generate acid (MPA), then the NAPP of the material is negative. Conversely, if the MPA exceeds the ANC, the NAPP of the material is positive. A NAPP assessment involves a series of analytical tests that include:
Determination of pH and EC
pH and EC measured on 1:5 w/w water extract. This gives an indication of the inherent acidity and salinity of the waste material when initially exposed in an emplacement area.
Total sulfur content and Maximum Potential Acidity (MPA)
Total sulfur content is determined by the Leco high temperature combustion method. The total sulfur content is then used to calculate the MPA, which is based on the assumption that the entire sulfur content is present as reactive pyrite. Direct determination of the pyritic sulfur content can provide a more accurate estimate of the MPA.
Acid neutralising capacity (ANC)
The ANC is determines by addition of acid to a known weight of sample, then titration with NaOH to determine the amount of residual acid. The ANC measures the capacity of a sample to react with and neutralise acid. The ANC can be further evaluated by slow acid titration to a set end-point in the Acid Buffering Characteristic Curve (ABCC) test through calculation of the amount of acid consumed and evaluation of the resultant titration curve.
Geochemistry Report: Eastern Leases Project
Page A3
Net acid producing potential (NAPP)
Calculated from the MPA and ANC results. The NAPP represents the balance between a sample’s inherent capacities to generate and neutralise acid. If the MPA is greater than the ANC then the NAPP is positive. If the MPA is less than the ANC then the NAPP is negative.
Net Acid Generation (NAG)
The net acid generation (NAG) test involves the addition of hydrogen peroxide to a sample of mine rock or process residue to oxidise reactive sulfide, then measurement of pH and titration of any net acidity produced by the acid generation and neutralisation reactions occurring in the sample. A significant NAG result (i.e. final NAGpH < 4.5) indicates that the sample is potentially acid forming (PAF) and the test provides a direct measure of the net amount of acid remaining in the sample after all acid generating and acid neutralising reactions have taken place. A NAGpH > 4.5 indicates that the sample is non-acid forming (NAF). The NAG test provides a direct assessment of the potential for a material to produce acid after a period of exposure and weathering and is used to refine the results of the theoretical NAPP predictions. The NAG test can be used as a stand-alone test, but is recommended that this only be considered after site specific calibration work is carried out.
ASSESSMENT OF ELEMENT ENRICHMENT AND SOLUBILITY In mineralised areas it is common to find a suite of enriched elements that have resulted from natural geological processes. Multi-element scans are carried out to identify any elements that are present in a material (or readily leachable from a material) at concentrations that may be of environmental concern with respect to surface water quality, revegetation and public health. The samples are generally analysed for the following elements:
Major elements Al, Ca, Fe, K, Mg, Na and S.
Minor elements As, B, Cd, Co, Cr, Cu, F, Hg, Mn, Mo, Ni, Pb, Sb, Se and Zn.
The concentration of these elements in samples can be directly compared with relevant state or national environmental and health based concentration guideline criteria to determine the level of significance. Water extracts are used to determine the immediate element solubilities under the existing sample pH conditions of the sample. The following tests are normally carried out:
Multi-element composition of solids.
Multi-element composition of solid samples determined using a combination of ICP-mass spectroscopy (ICP-MS), ICP-optical emission spectroscopy (OES), and atomic absorption spectrometry (AAS).
Multi-element composition of water extracts (1:5 sample:deionised water).
Multi-element composition of water extracts from solid samples determined using a combination of ICP-mass spectroscopy (ICP-MS), ICP-optical emission spectroscopy (OES), and atomic absorption spectrometry (AAS).
Under some conditions (e.g. low pH) the solubility and mobility of common environmentally important elements can increase significantly. If element mobility under initial pH conditions is deemed likely and/or subsequent low pH conditions may occur, kinetic leach column test work may be completed on representative samples.

KINETIC LEACH COLUMN TESTS Kinetic leach column (KLC) tests can be used to provide information on the reaction kinetics of mine waste materials. The major objectives of kinetics tests are to:
Provide time-dependent data on the kinetics and rate of acid generation and acid neutralising reactions under laboratory controlled (or onsite conditions);
Investigate metal release and drainage/seepage quality; and Assess treatment options such as addition of alkaline materials.
The KLC tests simulate the weathering process that leads to acid and base generation and reaction under laboratory controlled or site conditions. The kinetic tests allow an assessment of the acid forming characteristics and indicate the rate of acid generation, over what period it will occur, and what management controls may be required.
In KLC tests, water is added to a sample and the mixture allowed to leach products and by-products ofacid producing and consuming reactions. Samples of leachate are then collected and analysed. Intermittent water application is applied to simulate rainfall and heat lamps are used to simulate sunshine. These tests provide real-time information and may have to continue for months or years. Monitoring includes trends in pH, sulfate, acidity or alkalinity, and metals, for example. The pH of the collected leachate simulates the acid drainage process, acidity or alkalinity levels indicate the rate of acid production and acid neutralisation, and sulfate production can be related to the rate of sulfide oxidation. Metal concentration data provides an assessment of metal solubility and leaching behaviour.
Figure A1 shows the kinetic leach column set up used by RGS adapted from AMIRA, 2002. The columns are placed under heat lamps to allow the sample to dry between water additions to ensure adequate oxygen ingress into the sample material.
Approximately 2 kg of sample is accurately weighed and used in the leach columns depending on the physical nature of the material and particle size. Some materials can be used on an as-received basis (i.e. no crushing as with process residues and tailings materials), whereas others are crushed to nominal 5-10 mm particle size (as with overburden).
The sample in the column is initially leached with deionised water at a rate of about 400 ml/kg of sample and the initial leachate from the columns collected and analysed. Subsequent column leaching is carried out at a rate of about 400 ml/kg per month or quarterly, and again collected and analysed. The leaching rate can be varied to better simulate expected site conditions or satisfy test program data requirements.
The column must be exposed to drying conditions in between watering events. The residual water content and air void content in the column can be determined by comparing the wet and dry column weights. A heat lamp is generally used above the sample during daylight hours to maintain the leach column surface temperature at about 30oC.
