Cowal Gold Project – Addendum to the Transport of Hazardous Materials Study On 7 February 2017 the Cowal Gold Project’s (the Project) Development Consent (DA 14/98) was modified to reflect approval of the Mine Life Modification. The Mine Life Modification involves an extension of the Project’s operational mine life for an additional eight years (i.e. to end 2032) and an increase to the depth of the existing open pit (among other things). During the preparation of the Mine Life Modification, Evolution identified an alternative transport route that involves direct road transport of sulphuric acid from Port Kembla, to the Project. Accordingly, this Addendum to the Transport of Hazardous Materials Study (THMS) has been prepared to reflect the alternate transport route for sulphuric acid. This Addendum includes an updated assessment of the likelihood of a hazardous incident along the revised transport route for the delivery of sulphuric acid to the Project, and an update to the risk analysis results. COWAL GOLD PROJECT ADDENDUM TO THE TRANSPORT OF HAZARDOUS MATERIALS STUDY JULY 2018 Project No. HAL-02-07 Document No. 922533 Sulphuric Acid Road Transport Route Evaluation – Overview ADDENDUM Transport of Hazardous Materials Study 1. Given the proposed route change, hydrochloric acid and sulphuric acid are no longer following the same route and cannot be assessed together. As such, consider the attachments in this Addendum as an additional attachment (i.e. Attachment 8) to the original THMS. 2. Include the new Attachment 8A provided in this document. 3. Include the new Attachment 8B provided in this document. 4. Include the new Attachment 8C provided in this document. 5. Include the new Attachment 8D provided in this document. 6. Split Section 4.2 of the THMS into 4.2(a) and 4.2(b) and insert the text below as Section 4.2(b): Road transport of sulphuric acid within NSW begins at Port Kembla and terminates at the Project. The road transport route for sulphuric acid to the Project has been divided into four segments (Segments 1 to 4) for the purpose of route evaluation. Route evaluations for Segments 1 to 4 are attached to the THMS as Attachments 8A, 8B, 8C and 8D respectively. An overview of Segments 1 to 4 is provided below. Segment 1 Attachment 8A Transport of sulphuric acid from Port Kembla to the Hume Highway (Sydney) Segment 2 Attachment 8B Transport of sulphuric acid from the Hume Highway (Sydney) to Temora Segment 3 Attachment 8C Transport of sulphuric acid from Temora to West Wyalong Segment 4 Attachment 8D Transport of sulphuric acid from Newell Highway/Mid Western Highway (West Wyalong) to the Cowal Gold Project A summary of the outcomes of the route evaluations for Segments 1 to 4, including the identification of suitable transport routes, is provided below. The overall sulphuric acid transport route to the Project and suitable transport routes for Segments 1 to 4 are shown on Figures 9a, 9b and 9c. 00927525 1 Evolution Mining (Cowal) Pty Limited QUEENSLAND MOREE WALGETT BOURKE NARRABRI COFFS HARBOUR ARMIDALE NEW SOUTH WALES NYNGAN DUNEDOO DUBBO MUSWELLBROOK SINGLETON South For SEGMENT 4 NEWCASTLE MOLONG detail see Figure 9c PARKES COWAL BATHURST GOLD 535 PROJECT ML1 Pacific GRENFELL COWRA SYDNEY WEST WYALONG For SEGMENT 1 SEGMENT 3 detail see Figure 9b (Route 3B) MIRROOL YOUNG TEMORA WOLLONGONG Port Kembla Ocean GOULBURN SEGMENT 3 YASS NARRANDERA (Route 3A) WAGGA WAGGA SEGMENT 2 (Route(Route 2A) A.C.T.

The route is assessed as posing a minimal to acceptable level of risk to surrounding people, property and the natural environment. Therefore, Route 1A is suitable for the transport of sulphuric acid for Segment 1. Risk management measures required to be implemented by the material supplier and transport provider for the transport of sulphuric acid to the Project are set out in Attachment 8A. Table 9a Sulphuric Acid – Segment 1 – Suitable Transport Routes Route Directions 1A On exiting Foreshore Road, Port Kembla, turn right onto Old Port Road which becomes Flinders Street, turn right onto Five Islands Road then right onto M1 Princes Motorway then left onto Picton Road on left onto the Hume Highway. Route 1A is shown on Figure 9b. Segment 2 Route 2A (Table 9b) has been identified as the only potential available route for heavy vehicles for Segment 2 and is suitable for the transport of hazardous materials when tested against mandatory considerations, subjective factors, road and traffic factors, emergency response capability, operational factors and risk (including environmental and landuse factors). Route 2A is assessed as posing a minimal level of risk to surrounding people, property and the natural environment. This route has also been recommended by the RMS and transport provider for the transport of hazardous materials. Consultation with Councils regarding Route 2A will also be undertaken and Council comments will be taken into consideration by the THMS. Risk management measures required to be implemented by the material supplier and transport provider for the transport of sulphuric acid to the Project are set out in Attachment 8B. Table 9b Sulphuric Acid – Segment 2 – Suitable Transport Route Route Directions 2A From the Hume Highway (Glenfield), continue on the Highway until Bowning (west of Yass). Turn off the Hume Highway into State Route 94 (Burley Griffin Way) and continue to Temora. Route 2A is shown on Figure 9a. 00927525 5 Evolution Mining (Cowal) Pty Limited Sulphuric Acid Road Transport Route Evaluation – Overview Segment 3 Routes 3A and 3B (Table 9c) have been identified as potential available routes for heavy vehicles for Segment 3 and are suitable for the transport of hazardous materials when tested against mandatory considerations, subjective factors, road and traffic factors, emergency response capability, operational factors and risk (including environmental and landuse factors). Both routes are assessed as posing a minimal to acceptable level of risk to surrounding people, property and the natural environment. Therefore, Routes 3A and 3B are both suitable for the transport of sulphuric acid for Segment 3. Risk management measures required to be implemented by the material supplier and transport provider for the transport of sulphuric acid to the Project are set out in Attachment 8C. Table 9c Sulphuric Acid – Segment 3 – Suitable Transport Routes Route Directions 3A On entering Temora, continue along Burley Griffin Way (State Route 94) to the Newell Highway south of Mirrool. Turn right onto the Newell Highway and continue to the Newell Highway/Mid Western Highway (West Wyalong). 3B On entering Temora, turn right into Barmedman Road (State Route 85) and continue to Wyalong. At Wyalong turn left onto the Newell Highway and continue to West Wyalong. On entering West Wyalong, take the town heavy vehicle bypass route (Turn left into Copeland Street which becomes Railway Road. Take the first left off Railway Road and cross over the Temora-Lake Cargelligo Railway line. After crossing the railway line, turn immediately right and follow the railway line to the Newell Highway). Turn right onto the Newell Highway and continue to West Wyalong. Turn left into the Mid Western Highway until the junction with Ungarie Road. Routes 3A and 3B are shown on Figure 9a. Segment 4 Route 4A (Table 9d) has been identified as the only potential available route for heavy vehicles for Segment 4 and is suitable for the transport of hazardous materials when tested against mandatory considerations, subjective factors, road and traffic factors, emergency response capability, operational factors and risk (including environmental and landuse factors). Route 4A is assessed as posing a minimal level of risk to surrounding people, property and the natural environment. This route is also the approved Project Access Road.
