The WEPC is located approximately 10 km north of Bendigo. Figure 1 depicts the WEPC area and the surrounding area. 1.1 Project Background The WEPC is a purpose built water management facility, which forms part of the gold mining operations in the Bendigo region. Groundwater containing naturally occurring salts and metals is pumped to the site to evaporate as a part of mine dewatering. With active mining in the region coming to an end, DELWP is coordinating the development of options for the management of groundwater in mine voids beneath Bendigo. As part of this broader study by DELWP, and in response to community concerns about the WEPC, DELWP commissioned the sampling and analysis of water samples from domestic rainwater tanks and surface soils in the vicinity of the WEPC. The community concerns were raised over the potential for the ponds to dry out, with dust from the ponds potentially carried by the wind, deposited onto nearby land (including roofs), and entering nearby rainwater tanks used for drinking water purposes. 1.2 Objectives The objective of this assessment was to carry out a baseline investigation, assessing if off-site migration of sediments sourced from the WEPC has resulted in elevated concentrations of metals in domestic rainwater tank water and in surface soils in the vicinity of the ponds. The scope of works was to: Assess the concentrations of metals in primary domestic rainwater tanks used for drinking water supply in the vicinity of the WEPC. Establish the current baseline conditions of metal concentrations in surface soils in the vicinity of the WEPC. Domestic rainwater tanks were considered to be those tanks currently or regularly supplying drinking water for the property. 1.3 Scope of Work Undertaken The scope of work undertaken was in part specified in the request for quotation (from DELWP, 25 March 2015), and further detailed in the Senversa proposal response dated 7 April 2015. The Sampling and Analysis Plan (SAP), 17 June 2015, (Senversa, 2015) was also prepared prior to conducting field-based investigation works. In summary, the investigation scope included: Preparation of the SAP, including approximation of the number of domestic rainwater tanks within 1,000m of the WEPC, development of a soil sampling regime and development of analytical schedules for both soil and water samples. Collection of samples from domestic rain water tanks within the sampling area. A total of 53 samples were collected from around the ponds. m11135_009_rtp_rev3 1 Introduction Collection of a background domestic tank water sample located approximately 3.5 km south of the WEPC. Collection of 50 soil samples from within the sampling area. Analysis of soil and water samples for chemicals of potential concern (CoPC) by laboratories accredited by National Association of Testing Authorities Australia (NATA) for the analysis methods used. Data quality assurance and quality control (QA/QC) procedures. Preparation of individual letter reports outlining analytical results for each individual property where sampling was conducted. Preparation of this report. m11135_009_rtp_rev3 2 Background Information 2.0 Background Information A description of the site and regional environmental setting is summarised in the following sections. 2.1 Investigation Area Details The WEPC is owned by Unity Mining Ltd. The study area extended approximately 1km from the edge of the ponds in all directions. Land uses surrounding the ponds include: A rail line to the west and public roads (sealed and unsealed). Private properties. Low density residences. Grazing and cropping paddocks. Greater Bendigo National Park. Land uses beyond the investigation area continue on as listed above. Figure 1 depicts the boundary of the WEPC and the surrounding area. 2.2 Environmental Setting 2.2.1 Topography, Drainage and Nearest Surface Water Body A topographical map was obtained for the site from www.land.vic.gov.au on 23 March 2015. The information obtained from the Department of Transport, Planning and Local Infrastructure Planning Maps Online resource indicates that the southern portion of the ponds are subject to inundation. During the field works, the investigation area was observed to be relatively flat. The nearest surface water bodies in and around the investigation area were: Several dams present on farmland properties in all directions from the ponds. Myers Creek located approximately 410 m west of the ponds. Nuggety Gully (ephemeral) located approximately 180-520 m north of the ponds. Snowball Gully (ephemeral) located approximately 850 m to the south east of the ponds. 2.2.2 Regional Geology The Geological Society of Victoria 1: 50,000 Raywood Sheet indicates that the area is directly underlain by the Ordovician Castlemaine Supergroup comprised of sandstone, turbiditic, siltstone, black shale with rare limestone including coarse amalgamated beds and displaying crossbedding and grading. Mudstones (carbonaceous and fossiliferous) present are massive to finely laminated. The geologic sequence is generally a fining upward sequence. The Castlemaine Supergroup is overlain by Deep Lead sediments that outcrop in this area. These sediments typically comprise of ferruginised mature quartz gravels fining upwards to sand and clay. The Deep Lead is overlain by the Shepparton Formation, which is comprised of Quaternary aged alluvial and colluvium sediments such as clay, silt sand and gravel. The surface sediments across the investigation area are generally comprised of the Shepparton Formation. This geology of the investigation area is presented in the map below. m11135_009_rtp_rev3 3 Background Information WEPC Extract from Geological Society of Victoria – Raywood (1:50,000) Map sheet (2001) NWS = Shepparton Formation, Occ/Och/Ocb = Ordovician Basement , Qc = Quaternary Colluvial Sediments Elevated naturally occurring arsenic in soils are common in the region, particularly associated with gold bearing units (Geoscience Australia, 2003). The naturally occurring arsenic can be reported at concentrations up to several hundred milligrams per kilogram in natural soils in Bendigo, and at even higher concentrations in mine related waste rock and overburden (Hinwood et al, 1998). 2.2.3 Regional Hydrogeology Available hydrogeological mapping for the Bendigo region (1:125,000 Map of Bendigo and Part of Deniliquin, published by the Department of Industry, Technology and Resources) used in conjunction with previous groundwater investigations at the site (URS, 2014), indicates the primary aquifer is the Shepparton Formation, which consists of semi-confined to unconfined alluvial and colluvial aquifers, comprised of sand and silt (likely to be minor on a regional scale). The broader regional groundwater flow is expected to be towards the north west along the regional fold axis, prior to discharge in to the Murray Basin sediments of the Shepparton Formation. 2.3 Potential Contaminants of Concern Based on the information presented within the previous reports, the primary contaminants of potential concern (CoPC) in areas surrounding the WEPC were considered to be accumulated metals and metalloids from the water and sediments within the ponds. m11135_009_rtp_rev3 4 Regulatory Framework for Assessment 3.0 Regulatory Framework for Assessment The following sections outline the regulatory framework used in the assessment and details relevant objectives and/or investigation levels which have been adopted. 3.1 Soil 3.1.1 Regulatory Framework The State Environment Protection Policy (Prevention and Management of Contamination of Land) 2002 (SEPP (PMCL)) sets out the regulatory framework for the prevention and management of contaminated land within the State of Victoria. The intent of this framework is to maintain and maximise, to the extent practicable, the quality of the land environment in Victoria, in order to protect its existing and potential beneficial uses. The SEPP (PMCL) was declared in June 2002 in accordance with Section 16 of the Environment Protection Act, 1970, and EPA Victoria is responsible for its implementation. The SEPP (PMCL) identifies a range of land use categories and relevant protected beneficial uses for each of these categories, as well as indicators (chemical or other characteristics) and objectives for these indicators to determine whether the level of an indicator may pose an unacceptable risk to (i.e. precludes) protected beneficial uses. 3.1.2 Protected Beneficial Uses of Land As discussed in Section 2.1, the investigation area contains multiple land uses including low density residences, farming paddocks and a national park. The potential future uses of the site are anticipated to remain the same. In line with the objectives of the assessment, human health and maintenance of ecosystems have been assessed as protected beneficial uses of land. Other beneficial uses protected under SEPP (PMCL) include buildings and structures, aesthetics, and the production of food, flora and fibre); these are considered generally protected by adopting human health and maintenance of ecosystems objectives as initial screening criteria. 3.1.3 Soil Quality Objectives Human Health The SEPP (PMCL) states that the level of a chemical substance or waste must not be greater than the investigation level specified for human health in the NEPM. Schedule B(1) of the current version of the NEPM (NEPC, 2013) provides a range of investigation levels for the protection of human health, referred to as Health-based Investigation Levels (HILs). HILs and are provided for four generic land use settings as follows: HIL A – Residential with garden/accessible soil (home-grown produce contributing less than 10% of vegetable and fruit intake; no poultry). This category also includes children’s day-care centres, kindergartens, preschools and primary schools. HIL B – Residential with minimal opportunities for soil access. Includes dwellings with fully and permanently paved yard space such as high-rise apartments and flats. HIL C – Public open space such as parks, playgrounds, playing fields (e.g. ovals), secondary schools and footpaths. It does not include undeveloped public open space (such as urban bushland and reserves) which should be subject to a site-specific assessment where appropriate. HIL D – Commercial/industrial such as shops, offices, factories and industrial sites. m11135_009_rtp_rev3 5 Regulatory Framework for Assessment It is emphasised within the NEPM that HILs are not intended for use as default remediation trigger criteria, but are intended to prompt an appropriate site-specific assessment of risk when they are exceeded. This is consistent with Table 2 of the SEPP (PMCL), which allows for objectives derived using a risk-based methodology to be adopted in place of HILs. Based on the current and foreseeable future land use at the investigation area, NEPM HIL A values have been used for comparison with reported soil conditions at the site. Maintenance of Ecosystems (MoE) The SEPP (PMCL) states that the level of a chemical substance or waste (indicator) must not be greater than any regional Ecological Investigation Level (EIL) developed in accordance with the National Environment Protection (Assessment of Site Contamination) Measure (“the NEPM”; NEPC, 2013), or until such time that a regional EIL applicable to the site is published, the Interim Urban EILs nominated in the NEPM. The current version of the NEPM (NEPC, 2013) specifies the following ecologically based investigation and/or screening levels: Default EILs for arsenic and lead. A methodology for derivation of site-specific EILs for nickel, chromium III, copper and zinc. The derivation process requires determination of ambient background concentrations (ABC) and added contaminant limits (ACLs) for these chemicals, and the EIL is then calculated as the ABC plus the ACL. The EILs have been developed for three generic land use settings, based on a range of species protection levels: Areas of ecological significance (99% species protection). Urban residential and public open space (80% species protection). Commercial and industrial (60% species protection). Based on the current and foreseeable future land use(s) at the site, EILs for ‘urban residential and public open space’ have been adopted for all soil samples. The guideline criteria for ‘areas of ecological significance’ have also been used for the three sampling locations within the Bendigo Greater National Park. For initial screening purposes, EILs for nickel, chromium III, copper and zinc have been derived for aged soils based on adoption of conservative screening assumptions regarding soil properties, as follows: EILs were calculated as the sum of the ABC and the ACL. ABCs were assumed to be the default (most conservative) values for aged soils with low traffic. ACLs were assumed to be the minimum (most conservative) values specified in Table 1B(1) to 1B(4) within NEPC (2013) Schedule B1. 3.2 3.2.1 Water Regulatory Framework The State Environment Protection Policy (Waters of Victoria) (SEPP (WoV)) sets out the regulatory framework for the protection of surface water in Victoria, however, tank drinking water is not specifically referenced under this guidance. SEPP WoV has therefore been consulted, but the assessment has focused on protection of human health from consumption of domestic tank water, in accordance with the objectives of this investigation. m11135_009_rtp_rev3 6 Regulatory Framework for Assessment 3.2.2 Protected Beneficial Uses of Water Given that tank water samples collected were from sources primarily used as domestic supply, the primary beneficial use is considered to be drinking water. Secondary uses for the water were considered likely to include stock watering and potential localised irrigation to nearby gardens. However, given the primary focus of the assessment is human health and the protection of drinking water supplies would generally represent the more conservative scenario, the secondary beneficial uses were not assessed separately. As the tank/domestic water was not in direct connection with protected surface waterways listed under SEPP WoV such as a creek or stream, maintenance of ecosystem guidelines were not applied for the purposes of this assessment. 3.2.1 Tank Water Quality Objectives The ANZECC (1992) drinking water guidelines were superseded by the National Health and Medical Research Council (NHMRC) Australian Drinking Water Guidelines (ADWG) in 2004. The ADWG were updated in 2011, with a further update in March 2015. These current ADWG were adopted, with the lower of the human health and/or aesthetic based values applied where relevant. For chemicals for which guidelines were not specified by NHMRC (2011), guidelines from the following alternative international sources were adopted (in order of preference): WHO (2011), Guidelines for Drinking Water Quality (and associated rolling revisions) USEPA (2015). Regional Screening Levels - Tap Water m11135_009_rtp_rev3 7 Investigation Methodology 4.0 Investigation Methodology The following sections describe the guidelines, standards and investigation methods adopted and used during the investigation. Additional information can also be found in the SAP (Senversa, 2015). 4.1 Standards and Guidance Documents The investigation, including the sampling, was performed in accordance with the following guidelines and standards: Australian Standard (AS 4482.1) - Guide to the Investigation and Sampling of Sites with Potentially Contaminated Soil, Part 2: Non-volatile and Semi-volatile compounds (2005). National Environment Protection Council (NEPC) - National Environment Protection (Assessment of Site Contamination) Measure 1999.

United States Environmental Protection Agency - Guidance on Systematic Planning Using the Data Quality Objectives Process EPA QA/G-4. United States Environmental Protection Agency - Guidance on Environmental Data Verification and Data Validation EPA QA/G-8. 4.2 Investigation Strategy The sampling program was designed to investigate the area most likely to be affected by wind-borne dust. As the greatest impacts from dust would be expected to occur closest to the ponds, rainwater tank and surface soil sampling was focused on properties within approximately 1,000 metres of the ponds. For rainwater tank samples, the preferred primary sampling location was the internal house tap where water is most commonly taken for drinking. Alternately, where the kitchen tap could not be accessed, samples were collected directly from the tank(s). Where tanks were sampled directly, the preference was to sample from a tap point on the tank. If a tap point was not available, then a disposable bailer was lowered into the tank. A background water sample was also collected approximately 3.5 km south of the WEPC. Soil samples were collected in a grid pattern across the wider study area. Sample locations ranged from 100 m to 1,000 m away from the WEPC. The location of a soil sample was as close to the preferred grid location as possible, however the actual location considered local site accessibility. Soil samples were collected from the surface (0.0-0.1 m below ground level (bgl)) at all locations and at one in ten locations, a soil bore was advanced deeper (to 0.3-0.5 m bgl) for use as a background comparison sample. Figure 2 presents the soil sampling locations, with the shaded areas representing properties where tank water samples were collected. m11135_009_rtp_rev3 8 Investigation Methodology 4.2.1 Additional Works In order to provide context to the soil and water results surrounding the ponds against the potential sources within the ponds, one water sample was collected from the New Moon discharge (Sample ID: NM). The water sampled is pumped from the New Moon mine shaft directly to the ponds. The sampling locations are shown on Figure 2. Sediment samples from Pond 7 of the WEPC were collected in early 2015 as part of a previous environmental investigation. The average, median, maximum and minimum concentrations are provided in Table 7. This information was used to characterise the potential dust source from the WEPC, and to assist in assessment of the analytical water tank results and soil samples results against the mine water and surface sediments in the WEPC. 4.3 Investigation Program The following table describes the methodology undertaken during the fieldworks program: Activity Item Description Tank Water Sample Collection Date 2-18 June 2015 Method Sampling was undertaken with reference to EPA668 and EPA669, and consisted of: Collecting sample from main kitchen sink or tap in the first instance. Running the water for approximately 30 seconds prior to filling sample bottles to flush out stagnant water within the pipe lines. If kitchen tap could not be accessed, the sample was collected directly from the nearest tap or water outlet supplied by the tank. If a water sample was collected directly from within the tank, a disposable bailer was used and the sample was collected from approximately mid-way through the tank water column, minimising sediment collection. Excess water was poured down the sink, into accessible drains, or the ground surface, as approved by the resident. Fresh disposable nitrile gloves were used prior to sample collection. The remainder of sampling equipment (disposable bailers) were single use only. Collection of quality control samples as defined in the SAP (Senversa, 2015), including field duplicate and secondary duplicates. Water samples were collected into clean, appropriately preserved laboratorysupplied bottles. Samples were stored and transported in chilled containers to the laboratories under standard CoC protocols in accordance with EPA669 and NEPM B2. All water samples were collected without filtering and assessed for total metal concentrations. Interviews were conducted with the current residents of the properties by Senversa field staff during water tank and/or soil sampling. A standard questionnaire developed in consultation with DELWP and DHHS was used for the assessment. A summary of questionnaire responses is provided in Table 2. Surface Soil Sample Collection Dates 2-12 June 2015 Method Sampling was undertaken with reference to IWRG701, A4482.1 and AS4482.2, and included the following: Surface samples (0-0.1 m bgl) were collected from a total of 40 locations. Soil sampling was undertaken using a stainless steel trowel and/or a hand auger. Soil samples was collected directly from the trowel or hand auger using disposable nitrile gloves and placed in a laboratory supplied glass jar for sample analytical purposes. A deeper sample (approximately 0.5 m bgl) was collected from one in four bore holes. The actual depth of sampling varied at some locations due to refusal of the hand auger, with the actual depth sampled recorded. Collection of quality control samples as defined in the SAP (Senversa, 2015), m11135_009_rtp_rev3 9 Investigation Methodology Activity Item Description included field duplicate and secondary duplicates. Where re-useable sampling equipment was used, such as hand augers and trowels, this equipment was decontaminated to minimise gross crosscontamination prior to collection of another sample. GPS coordinates for each soil bore location were recorded after sampling. Fresh disposable nitrile gloves were used prior to sample collection and soil sampling equipment (i.e. hand auger and trowel) was decontaminated after each use. Soil samples were collected into clean laboratory-supplied jars to zero headspace. Samples were stored and transported in chilled containers to the laboratories under standard Chain of Custody (CoC) protocols in accordance with relevant guidelines. A summary of the lithology encountered for shallow and deep soil bores is provided in Appendix A. Date New Moon Discharge Water Sample Methods Collection 4.3.1 5 June 2015 A Unity Mining Ltd representative accompanied Senversa field staff to the location of the New Moon Mine discharge point and a sample was collected directly into a clean, appropriately-preserved laboratory-supplied sample bottle and immediately stored in a chilled container. A dedicated pair of disposable nitrile gloves were worn during sampling. Water Quality Parameters For all water samples collected in this assessment, field water quality parameters were measured for pH, temperature, total dissolved solids (TDS) (as Electrical Conductivity (EC)), redox potential and dissolved oxygen using a supplier-calibrated field water quality meter. Field water quality parameters are summarised within Table 1 and the water quality meter calibration certificates are provided in Appendix B. 4.4 Laboratory Analysis The primary laboratory used for conducting the soil and water analyses was Eurofins/mgt Australia Pty Ltd (Eurofins). Australian Laboratory Services Pty Ltd (ALS) was engaged as the secondary laboratory. Soil and water samples collected were analysed by the primary laboratory for the following. Matrix Soil No. of Samples 50 Analytes Selected metals and metalloids – As, Ba, Be, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, Sn, Se, V and Zn. Electrical conductivity and pH.

Selected Ionic species – F, K, Ca, Mg, Na, SO4 and Cl. Rinsate 6 Selected metals – As, Cd, Cr, Cu, Ni, Pb and Zn. m11135_009_rtp_rev3 10 Investigation Methodology The laboratory certificates of analysis have been provided in Appendix C. 4.5 Quality Assurance / Quality Control The QA/QC procedures adopted by Senversa provide a consistent approach to evaluation of whether the data quality objectives (DQO’s) required by the project have been achieved. The process focuses on assessment of the useability of the data in terms of accuracy and reliability in forming conclusions on the condition of the element of the environment being investigated. The approach is based on the guidance listed in Section 4.1. The limit of reporting for antimony was higher than the drinking water guideline in five of the 54 primary drinking water samples (with 53 samples collected in the investigation area and one background sample collected approximately 2.5 km away). However, antimony was not considered a metal of concern associated with the WEPC, based on the available sampling data from the wider area. The raised detection limit was not considered to affect the outcome of the assessment. Based on the results of the data validation, the data is considered suitable for use in forming conclusions relating to the contamination status at the site. Further discussion on the quality and validity of data is included in Appendix D. m11135_009_rtp_rev3 11 Water Results 5.0 Water Results The results of the sampling provide data on the quality of domestic tank water in the area surrounding the WEPC. Additionally, data was obtained to characterise the discharge water which enters the WEPC and the Bendigo Creek. 5.1 Water Quality Parameters The following table presents a comparison of the water quality parameters collected from the domestic tank water samples (presented as a range) and water quality from other sources. All water quality parameters for drinking water samples are presented as Table 1, attached. The properties from which samples were collected are shown on Figure 2. Water Quality Parameter Unit Domestic Tank Water New Moon Discharge (Range) pH unit 4.6-9.2 6.66 µS/cm 19.2-810 7084 mg/L 2.5-20.9 6.88 Temperature °C 6.7-16.9 21.3 Redox Potential mV -39.1-349.9 -206.7 Electrical Conductivity Dissolved Oxygen A strong hydrogen sulphide odour was noted from the New Moon sample. In comparison to the tank water samples, the New Moon sample recorded a lower DO, higher temperature and lower redox, indicating the groundwater being pumped to the surface was representative of underground conditions. 5.2 Tank Water Laboratory Results The water laboratory analytical reports have been provided within Appendix C and all tank water results summarised against the ADWG in Table 3. The results of this investigation indicate that a number of metals within the tank drinking water samples were present at concentrations exceeding the potable water quality objectives. The analytical data for the compounds reported above the drinking water guidelines and arsenic (a central contaminant of interest) are presented below. Note that only the 53 tank water samples from the investigation area (i.e. excluding the single background sample) are presented in the following charts. m11135_009_rtp_rev3 12 Water Results 5.2.1 Arsenic There were no tank water samples which reported arsenic concentrations above the potable water guideline of 0.01 mg/L. The New Moon sample reported an arsenic concentration of 3.01 mg/L, which is two orders of magnitude above the potable water guideline.

It is noted that six of the samples reported antimony results which had raised detection limits; this was not considered to affect the outcome of the assessment and is further discussed in Appendix D. The New Moon sample reported an antimony concentration below the limit of detection, at <0.003 mg/L. 50 45 Antimony Concentrations in Tank Water Samples 45 40 35 30 25 20 15 10 6 5 0 1 Below limit of detection (<0.003 mg/L) Below limit of detection (<0.005 mg/L) 1 Equal to the limit of detection Above drinking water guideline (0.003 mg/L) (>0.003 mg/L) m11135_009_rtp_rev3 13 Water Results 5.2.3 Cadmium There was one tank water sample that reported a cadmium concentration above the potable water guideline of 0.002 mg/L, with a concentration of 0.0026 mg/L.

The New Moon sample reported a lead concentration of <0.001 mg/L. The background sample did report a concentration above the potable water guideline limit, however, as these charts present the investigation area results when considered with the New Moon sample, it is not presented here. The background sample is further discussed in the table in Section 5.2.7.

The New Moon sample reported a manganese concentration of 0.98 mg/L, which is above the potable water guideline for protection of aesthetic values and the protection of health (0.5 mg/L). Manganese Concentrations in Tank Water Samples 30 27 25 25 20 15 10 5 1 0 Below limit of detection (<0.001 mg/L) 5.2.6 Above limit of detection and below drinking water guideline (0.001 - 0.1 mg/L) 0 Above drinking water guideline - Aesthetic (0.1 mg/L) Above drinking water guideline - Health (0.5 mg/L) Zinc There were eight tank water samples which reported zinc concentrations above the potable water guideline of 3 mg/L, with a concentration range of 3.2-13 mg/L. The New Moon sample reported a zinc concentration of 0.017 mg/L, which is below the potable water guideline. Zinc Concentrations in Tank Water Samples 50 45 45 40 35 30 25 20 15 8 10 5 0 0 Below limit of detection (<0.001 mg/L) Above limit of detection and below drinking water guideline (0.001 - 3 mg/L) Above drinking water guideline (>3 mg/L) m11135_009_rtp_rev3 15 Water Results 5.2.7 Summary of Exceedences These guideline exceedences within the drinking water samples are discussed further in the following table. Metal Antimony Sample Guideline Comments Exceedences Type T30 Health The presence of antimony may be associated with a number of potential sources, such as dust deposition into the tanks from a soil source with elevated antimony or rainwater interacting with solder and plastics, which are known sources of antimony as noted in the ADWG. Antimony concentrations greater than the guideline value were not reported in other properties within the sampling area, and the source does not appear to be widespread. The household with concentrations of antimony above the ADWG have been advised to seek advice from the DHHS on how best to manage their tank system. The limit of reporting for antimony was higher than the drinking water guideline in six of the 54 primary drinking water samples. This is further discussed in Appendix D. Cadmium T44 Health The presence of cadmium may be associated with a number of potential sources, such as dust deposition into the tanks from a soil source with elevated cadmium, or, as noted in the ADWG, cadmium can be found in water as a result of impurities in the zinc of galvanised pipes or in solders used in fittings, water heaters, water coolers and taps. Cadmium concentrations greater than the guideline value were not reported in other properties within the sampling area, and the source of cadmium does not appear to be widespread. Lead T17, T53* Health The presence of lead may be associated with a number of potential sources, such as dust deposition into the tanks from a soil source, or from degradation of nearby lead paint, or due to water interacting with natural sources or household plumbing containing lead (e.g. pipes, solder), as stated in the ADWG. The lead concentration above the ADWG value was confined to a single tank on one property and was not reported in other properties within the sampling area. Lead was also reported above the ADWG value from the background property sample, collected outside the WEPC investigation area. The background sample was collected from the kitchen tap, which sourced water from three interconnected tanks. These two households with concentrations of lead above the ADWG have been advised to seek advice from the DHHS on how best to manage their tank system. Manganese T15 Aesthetic The presence of manganese may be associated with a number of potential sources, such as dust deposition into the tanks from a soil source with manganese, or through rainwater interacting with metal roofing, guttering, tanks etc. There are both health and taste based criteria for manganese, and while the manganese concentration in sample T15 was above the taste based criteria, it was below the health based criteria (0.5 mg/L). The concentration of manganese reported in the sample indicates that while a metallic taste may be present in the tank water, it is not a significant risk to human health. m11135_009_rtp_rev3 16 Water Results Metal Zinc Sample Guideline Comments Exceedences Type T09, T15, T22, T23, T26, T28, T30, T44 Aesthetic The ADWG states that the zinc criterion is based on taste only. There is no health based criterion for zinc, which is an essential element for humans. The presence of this metal may be associated with a number of potential sources, such as dust deposition into the tanks from a soil source with elevated zinc, or through rainwater interacting with metal roofing, guttering, tanks etc. The presence of zinc in rainwater tanks at concentrations exceeding the ADWG is not unusual given the prevalence of zinc within plumbing and roofing materials. The concentration of zinc reported in the sample indicates that while a metallic taste may be present in the tank water, it is not a significant risk to human health. * Background sample The detected concentrations of zinc and manganese in the tank waters were not considered to pose a significant risk to human health. The presence of lead, cadmium and antimony at concentrations exceeding the ADWG were not considered to be an acute risk to human health due to relatively minor exceedances of the drinking water criteria and based on likely / known tank usage (i.e. exposure) patterns. Concentrations of other metals and metalloids analysed (including arsenic) were below adopted drinking water guidelines in all tank water samples collected. 5.3 Comparison with New Moon Discharge Water Table 4 presents a comparison of the analytical results collected from the drinking water samples (presented as a statistical summary) and the New Moon discharge sample. Note that the limit of reporting (LOR) indicates the level below which the laboratory techniques can no longer report the compound with accuracy. A review of the analysis table indicates: Arsenic and manganese were reported in the New Moon Sample in elevated (i.e. above potable water guidelines) concentrations. The zinc average, median and maximum concentrations within the tanks samples were higher than in the New Moon sample. No antimony, beryllium, cadmium, copper, lead, mercury, molybdenum, selenium, tin or vanadium was detected above the laboratory LORs in the New Moon sample. The maximum concentrations of chromium, cobalt, nickel and zinc within the drinking water tank samples were higher than the concentrations reported in the New Moon Sample (this does not consider the compounds which were not detected in the New Moon sample, as listed above). 5.4 Directional and Distance Data Breakdown In order to assess if potential impacts from the WEPC were being influenced by wind direction or wind strength, a summary of the tank water results from the 53 samples has been presented on Figure 3 and Figure 4, based on direction and distance from the WEPC. The summary data is also presented in Table 8c and Table 8d. A review of the data distribution by distance and direction from the ponds did not reveal any significant spatial patterns. The presence of metals within potable water did not appear to be influenced by distance to or direction from the ponds. m11135_009_rtp_rev3 17 Soil and Sediment Results 6.0 Soil and Sediment Results The results of the soil investigation are summarised in the following sections. 6.1 Site Specific Geology Based on the soil investigation undertaken by Senversa, the generalised soil profile for the investigation area has been summarised as follows: 0.0-0.3 m approximately: Natural, orange-brown, silty clay with minor to trace fine-grained, rounded sand. Generally, increasing in stiffness with depth. 0.3-0.5 m approximately (maximum depth of investigation): Dark orange-brown or red-brown, hard to very stiff sandy clay / clayey sand with minor to trace silt. This compacted layer was identified at all 10 deeper investigation soil bores across the site. Bore logs and a lithological summary table for shallow bores are provided in Appendix A. 6.2 Field Observations All soils sampled are considered to be existing natural soils. No fill material was encountered. Where the soil sampling location grid fell on recently worked or sown soils, the sampling location was shifted to a less disturbed area (i.e. along a property fence line), where possible. These locations were considered more likely to be undisturbed natural soils. For the deeper investigation locations, a soil sample was collected at greater than 0.3 m bgl. This sample was considered to be representative of naturally-occurring background metals concentrations. The stiffness (i.e. extremely compacted and therefore undisturbed) of the clay prevented the hand auger from advancing further than 0.4 m bgl in several locations. Overall, there were no visual or olfactory signs of contamination (i.e. staining, organic odours, or anthropogenic material) noted during the soil investigation. 6.3 Soil Laboratory Results The soil laboratory test certificates are provided within Appendix C and are compared to relevant soil investigation levels in Table 5 and Table 6. The results present both the deeper and shallow surface samples. Metals in soils were largely below adopted screening criteria and metal concentrations at 0.3-0.5 m bgl were similar to those reported at the surface, providing limited evidence of metals accumulation at the surface. Exceedences of the adopted criteria are discussed below. 6.3.1 Maintenance of Modified Ecosystems Two samples QC17 and QC20 (quality control field duplicate samples for SB10_0.0-0.1 and SB27_0.0-0.1, respectively) reported nickel concentrations above the MoE guideline value. One sample (SB24_0.0-0.1) reported arsenic concentration above the adopted MoE guideline value. These isolated results are considered to be reflective of normal regional variability for metals levels in soil, and are not considered to be pose an ongoing risk to ecosystems that have adopted to the regional conditions, based on the average concentrations of surface soils in the area. m11135_009_rtp_rev3 18 Soil and Sediment Results 6.3.2 Human Health Of the 50 soil samples collected during the program (40 from the surface soils and ten from approximately 0.3-0.5 m below ground level), one reported an arsenic concentration of 120 mg/kg, which is above the human health (low density residential) guideline value of 100 mg/kg. The sampling location was within a paddock used for cropping. The samples surrounding SB25, including those collected closer to the ponds and closer to the nearest residence, reported lower arsenic concentrations. The isolated arsenic result is considered to be reflective of normal regional variability for arsenic levels in soil, which are reported as being up to approximately 200 mg/kg in central Victoria (Meaklim, 2004), and is not considered to be a risk to human health, based on the sample location and the average concentration of surface soils in the area. Metals in soils were largely below adopted screening criteria and metal concentrations at 0.3-0.5 m bgl were similar to those reported at the surface, providing limited evidence of metals accumulation at the surface (see Table 5 for full soil results). 6.4 Comparison with WEPC Sediment Samples Table 6 presents a comparison of the analytical results collected from the Pond 7 sediments in comparison to the surrounding surface soil sample results (presented as a statistical summary). The sampling locations are presented as Figure 5. A review of the table indicates: Arsenic was present in the pond samples at elevated concentrations. Arsenic concentrations were highly variable, ranging from 30-5,200 mg/kg in the twelve Pond 7 samples presented here. Nine of the twelve sediment samples were above the HIL A criterion of 100 mg/kg. The average surface soil concentration from the surrounding area was 15 mg/kg. No antimony, beryllium, cobalt, molybdenum or selenium was detected above the laboratory LORs in the Pond 7 samples. Manganese was present in the Pond 7 samples at elevated concentrations: Manganese concentrations were variable, ranging from 120-1,200 mg/kg in the twelve pond 7 samples. No sediment samples were above the HIL A guideline criteria of 3,800 mg/kg. The average surface soil concentration from the surrounding area was 154 mg/kg. Barium concentrations were reported as slightly elevated within Pond 7 sediments. No sediment samples were above the HIL A guideline criteria of 15,000 mg/kg. The average surface soil concentration from the surrounding area was 59 mg/kg. Concentrations were higher in the eastern part of the ponds, in the terraces closer to the discharge outlet. The analytical data for arsenic concentrations from the twelve samples collected from Pond 7 in comparison to the 50 soil samples collected from the investigation area are presented in the following chart. m11135_009_rtp_rev3 19 Soil and Sediment Results Distribution of Arsenic Concentartions in Pond Sediments and Residential Soils Number of samples 60 49 50 40 30 20 10 3 2 6 1 0 100-500 500-1000 0 <100 1 0 >1000 Arsneic concentartion ranges (mg/kg) Pond Sediments Resident Surface Soils The chart shows there was one arsenic concentration in soil samples above the low density residential guideline value of 100 mg/kg. 6.5 Directional and Distance Data Breakdown In order to assess if potential impacts from the WEPC were being influenced by wind direction or strength, a summary of the 40 surface soil results has been presented on Figures 3 and Figure 4 based on direction and distance from the WEPC. The summary data is also presented in Table 8a and Table 8b. A review of the data distribution by distance and direction from the ponds did not reveal any significant spatial patterns. The presence of metals within surface soils did not appear to be influenced by distance to or direction from the ponds. m11135_009_rtp_rev3 20 Data Trends 7.0 Data Trends The following table presents a summary of the data. The table aims to show the trend of metal concentrations across the discharge water, ponds sediments and data collected from resident’s tank water and surface soil. The table presents the trend data as a percentage based summary. This indicates the relative proportion of samples collected in each media and/or location which reported metal concentrations either above the limit of detection, or above the adopted guideline value. As there is only one sample from the New Moon discharge point, these data are not presented as a proportion/ percentage based value, but are a simple ‘yes/no’ to indicate presence or absence of metals. Where duplicate or split samples reported higher concentrations than the primary samples, these concentrations were adopted for the summary table.

The specific metals reported are considered to be reflective of the types of naturally occurring metals present within regional geological profiles and the associated groundwater. Many of the metals reported in the New Moon mine discharge water and sediments were therefore expected to be present in local soils. The table indicates that the distribution trend of metals within tank water differs from that reported in sediments, soils or mine water, with metals present in the mine water and pond sediments not necessarily present in the off-site tank water samples. For example, copper and antimony were reported in tank water but not in sediment or soils, whereas widespread vanadium and chromium in sediment and soils were not widely detected in tank water. The concentrations of metals within surface and deeper soils were considered to be reflective of normal regional variability. The concentrations of metals in water from storage tanks were considered reflective of normal conditions within domestic rain tank supplies, where interaction between metal materials (used in water storage tanks, roofing, plumbing etc.) and rain water may occur. m11135_009_rtp_rev3 22 Conclusions 8.0 Conclusions A summary of the investigation program of the soil and water sampling program around the Woodvale Evaporation Pond Complex can be summarised as follows: The WEPC is currently owned and operated by Unity Mining Ltd for management of groundwater associated with mine dewatering at nearby gold mining operations. The objectives of the sampling program were to assess the concentrations of metals in primary domestic rainwater tanks and surface soils in the vicinity of the WEPC. The sampling area included land within approximately 1 km of the ponds edges, in all directions. Sampling consisted of: Collection of 53 water samples from within the sampling area, as well as one background sample approximately 3.5 km from the ponds. Collection of 50 soil samples from within the sampling area, including both surface and deeper (0.5 m bgl) samples. Collection of a water sample from the New Moon mine shaft discharge. The results of the soil sampling considered together with sediment sampling previously conducted at the WEPC indicate: Arsenic concentrations were reported in one soil sample outside the WEPC above the human health (residential) guideline value. This isolated arsenic result is considered to be reflective of normal regional variability for arsenic levels in soil, and is not considered to be a risk to human health. The elevated concentrations of metals (predominately arsenic) encountered within the WEPC were not reproduced in soil sampling conducted outside the WEPC during this assessment. The results of the tank water sampling program (including comparison with the New Moon discharge sample) indicates: Zinc, lead, manganese, antimony and cadmium concentrations were reported in one or more water tank samples at concentrations above the drinking water guidelines. Zinc and manganese concentrations were above the aesthetic criteria but below health based criteria, and were therefore not considered to be a significant human health risk. Lead, antimony and cadmium concentrations exceeded drinking water guidelines. The presence of these metals in tank water above the adopted guidelines is commonly associated with plumbing, roofing and guttering materials. Concentrations of other metals and metalloids analysed (including arsenic) were below adopted drinking water guidelines in all tank water samples collected. The results and findings of the investigation and sampling program herein indicate that elevated metals (including manganese and arsenic) occur in mine discharge water and WEPC sediments. To date, metals have been concentrated in sediments at the surface of the WEPC through evaporation activities. Based on the information presented within this assessment, there is no definitive evidence that the WEPC complex is significantly impacting surrounding soils or residential tank water quality via off-site dust migration. m11135_009_rtp_rev3 23 Limitations and Uncertainty 9.0 Limitations and Uncertainty 9.1 Inherent Uncertainties and Limitations The investigation works herein are intended to develop and present sound, scientifically valid data concerning actual site conditions. Senversa does not seek or purport to provide legal or business advice. The following principles are an integral part of site contamination assessment practices and are intended to be referred to in resolving any ambiguity or exercising such discretion as is accorded the user or site assessor. Area Field Observations and Analytical Results Elimination of Uncertainty Some uncertainty is inherent in all site investigations. Furthermore, any sample, either surface or subsurface, taken for chemical testing may or may not be representative of a larger population or area. Professional judgment and interpretation are inherent in the process, and even when exercised in accordance with objective scientific principles, uncertainty is inevitable. Additional assessment beyond that which was reasonably undertaken may reduce the uncertainty. Failure to Detect Even when site investigation work is executed competently and in accordance with the appropriate Australian guidance, such as the National Environmental Protection (Assessment of Site Contamination) Amendment Measure (‘the NEPM’), it must be recognised that certain conditions present especially difficult target analyte detection problems. Such conditions may include, but are not limited to, complex geological settings, unusual or generally poorly understood behaviour and fate characteristics of certain substances, complex, discontinuous, random, or heterogeneous distributions of existing target analytes, physical impediments to investigation imposed by the location of services, structures and other man-made objects, and the inherent limitations of assessment technologies. Limitations of Information The effectiveness of any site investigation may be compromised by limitations or defects in the information used to define the objectives and scope of the investigation, including inability to obtain information concerning historic site uses or prior site assessment activities despite the efforts of the user and assessor to obtain such information.. Chemical Analysis Error Chemical testing methods have inherent uncertainties and limitations. Senversa routinely seeks to require the laboratory to report any potential or actual problems experienced, or non-routine events which may have occurred during the testing, so that such problems can be considered in evaluating the data. Level of Assessment The investigation herein should not be considered to be an exhaustive assessment of environmental conditions on a property. There is a point at which the effort of information obtained and the time required to obtain it outweigh the benefit of the information gained and, in the context of private transactions and contractual responsibilities, may become a material detriment to the orderly conduct of business. If the presence of target analytes is confirmed on a property, the extent of further assessment is a function of the degree of confidence required and the degree of uncertainty acceptable in relation to the objectives of the assessment. Comparison with The justification and adequacy of the investigation findings in light of the findings of a subsequent inquiry Subsequent should be evaluated based on the reasonableness of judgments made at the time and under the Inquiry circumstances in which they were made. Data Useability Investigation data generally only represent the site conditions at the time the data were generated. Therefore, the usability of data collected as part of this investigation may have a finite lifetime depending on the application and use being made of the data. In all respects, a future reader of this report should evaluate whether previously generated data are appropriate for any subsequent use beyond the original purpose for which they were collected, or are otherwise subject to lifetime limits imposed by other laws, regulations or regulatory policies. Nature of Advice The investigation works herein are intended to develop and present sound, scientifically valid data concerning actual site conditions. Senversa does not seek or purport to provide legal or business advice. m11135_009_rtp_rev3 24 Limitations and Uncertainty 9.2 Project Specific Uncertainties Specific uncertainties and limitations noted for this investigation are as follows: The assessment is based on a review of the condition of the site at the time of assessment. Senversa’s conclusions presented in this report are therefore based on the information available during the assessment. There is inherent uncertainty associated with environmental sampling, due to the nature of the environmental media, and temporal and spatial variability. While the soil and sediment data presented here is considered representative, results from these data are by necessity extrapolated across the wider area and may not capture all environmental variability. m11135_009_rtp_rev3 25 References 10.0 References EPA, 2009c.

analysis is reported. A recent review of our LIMS has resulted in the correction or clarification of some method identifications. Due to this, some of the method reference information on reports has changed. However, no substantive change has been made to our laboratory methods, and as such there is no change in the validity of current or previous results (regarding both quality and NATA accreditation). If the date and time of sampling are not provided, the Laboratory will not be responsible for compromised results should testing be performed outside the recommended holding time.

samples are submitted/analysed over several days, the last date of extraction and analysis is reported. A recent review of our LIMS has resulted in the correction or clarification of some method identifications. Due to this, some of the method reference information on reports has changed. However, no substantive change has been made to our laboratory methods, and as such there is no change in the validity of current or previous results (regarding both quality and NATA accreditation). If the date and time of sampling are not provided, the Laboratory will not be responsible for compromised results should testing be performed outside the recommended holding time.

Laboratory QC results for Method Blanks, Duplicates, Matrix Spikes, and Laboratory Control Samples are included in this QC report where applicable. Additional QC data may be available on request. 2. All soil results are reported on a dry basis, unless otherwise stated. 3. Actual LORs are matrix dependant. Quoted LORs may be raised where sample extracts are diluted due to interferences. 4. Results are uncorrected for matrix spikes or surrogate recoveries. 5. SVOC analysis on waters are performed on homogenised, unfiltered samples, unless noted otherwise. 6. Samples were analysed on an 'as received' basis. 7. This report replaces any interim results previously issued. Holding Times Please refer to 'Sample Preservation and Container Guide' for holding times (QS3001). For samples received on the last day of holding time, notification of testing requirements should have been received at least 6 hours prior to sample receipt deadlines as stated on the Sample Receipt Advice. If the Laboratory did not receive the information in the required timeframe, and regardless of any other integrity issues, suitably qualified results may still be reported. Holding times apply from the date of sampling, therefore compliance to these may be outside the laboratory's control. **NOTE: pH duplicates are reported as a range NOT as RPD UNITS mg/kg: milligrams per Kilogram mg/l: milligrams per litre ug/l: micrograms per litre ppm: Parts per million ppb: Parts per billion %: Percentage org/100ml: Organisms per 100 millilitres NTU: Nephelometric Turbidity Units MPN/100mL: Most Probable Number of organisms per 100 millilitres TERMS Dry Where a moisture has been determined on a solid sample the result is expressed on a dry basis. LOR Limit of Reporting. SPIKE Addition of the analyte to the sample and reported as percentage recovery. RPD Relative Percent Difference between two Duplicate pieces of analysis. LCS Laboratory Control Sample - reported as percent recovery CRM Certified Reference Material - reported as percent recovery Method Blank In the case of solid samples these are performed on laboratory certified clean sands. In the case of water samples these are performed on de-ionised water. Surr - Surrogate The addition of a like compound to the analyte target and reported as percentage recovery. Duplicate A second piece of analysis from the same sample and reported in the same units as the result to show comparison. Batch Duplicate A second piece of analysis from a sample outside of the clients batch of samples but run within the laboratory batch of analysis. Batch SPIKE Spike recovery reported on a sample from outside of the clients batch of samples but run within the laboratory batch of analysis. USEPA United States Environmental Protection Agency APHA American Public Health Association ASLP Australian Standard Leaching Procedure (AS4439.3) TCLP Toxicity Characteristic Leaching Procedure COC Chain of Custody SRA Sample Receipt Advice CP Client Parent - QC was performed on samples pertaining to this report NCP Non-Client Parent - QC performed on samples not pertaining to this report, QC is representative of the sequence or batch that client samples were analysed within TEQ Toxic Equivalency Quotient QC - ACCEPTANCE CRITERIA RPD Duplicates: Global RPD Duplicates Acceptance Criteria is 30% however the following acceptance guidelines are equally applicable: Results <10 times the LOR : No Limit Results between 10-20 times the LOR : RPD must lie between 0-50% Results >20 times the LOR : RPD must lie between 0-30% Surrogate Recoveries : Recoveries must lie between 50-150% - Phenols 20-130%. QC DATA GENERAL COMMENTS 1. Where a result is reported as a less than (<), higher than the nominated LOR, this is due to either matrix interference, extract dilution required due to interferences or contaminant levels within the sample, high moisture content or insufficient sample provided. 2. Duplicate data shown within this report that states the word "BATCH" is a Batch Duplicate from outside of your sample batch, but within the laboratory sample batch at a 1:10 ratio. The Parent and Duplicate data shown is not data from your samples. 3. Organochlorine Pesticide analysis - where reporting LCS data, Toxophene & Chlordane are not added to the LCS. 4. Organochlorine Pesticide analysis - where reporting Spike data, Toxophene is not added to the Spike. 5. Total Recoverable Hydrocarbons - where reporting Spike & LCS data, a single spike of commercial Hydrocarbon products in the range of C12-C30 is added and it's Total Recovery is reported in the C10-C14 cell of the Report. 6. pH and Free Chlorine analysed in the laboratory - Analysis on this test must begin within 30 minutes of sampling.Therefore laboratory analysis is unlikely to be completed within holding time. Analysis will begin as soon as possible after sample receipt. 7. Recovery Data (Spikes & Surrogates) - where chromatographic interference does not allow the determination of Recovery the term "INT" appears against that analyte. 8. Polychlorinated Biphenyls are spiked only using Arochlor 1260 in Matrix Spikes and LCS's. 9. For Matrix Spikes and LCS results a dash " -" in the report means that the specific analyte was not added to the QC sample. 10. Duplicate RPD's are calculated from raw analytical data thus it is possible to have two sets of data.
