Project Location

Project Area – 1675 hectares

Overall Process

5

Mining method

6 Pasture Re-seeding Topsoil Placement Fines Consolidation using amphiroles Sand Stacking Tailings Free flowing sand dozer Overburden Removal by Excavator Topsoil stripping by scraper Soil Conditioning

800m

• Conventional dry mining operation
• Ore slurried to processing plant
• Progressive mining sequence
• Two mining units and pits will be used after year 1
• Capacity of 1500 tph of ore treatment

Processing method

7

• Conventional wet gravity separation to concentrate the product
• Only uses water for mineral separation
• Percent solids of fine tailings increased in a thickener
• Sand tailings returned to mine void
• Fine tailings sent to tailings storage facility (the temporary TSF)

Rehabilitation and Restoration

Rehabilitation and Restoration

Mining Layout – first years

Water

11

• Water is required for:
• Processing of the ore (~ 2.5 GL per year)
• Dust management – spraying haul roads using water carts (370 ML per year)
• Site ablutions
• Offices and workshops
• Project will require approximately 3 GL of water per year
• Most water lost to:
• Seepage from sand tailings
• Evaporation from tailings

Water Management

12

How will water be managed by Kalbar? Kalbar’s water management plan aims to achieve the following:

• Minimise the amount of new water used by:

– Maximising water recovered from tailings – Capturing and using rain water falling in mine dams and mine void – Use “mine contact” rain water as process water – If required, managed discharge of treated mine contact water

• Minimise the impact on environmental flows to the Mitchell and Perry Rivers

– Controlled release of rain water falling on non-mining areas within project area – Prevent uncontrolled release of water from site by using water catchment management dams

• Have a positive impact on Mitchell River flow during summer months

– Release stored water from site in a controlled manner during summer months

Surface Water

13

• Water sourced from the Mitchell River as winterfill take and use licence
• Two options considered for off-take locations from the Mitchell River
• Water will be stored in a 2.2 GL fresh water dam within the project area
• Rain water falling away from mining activities will flow naturally from project area
• Rain water falling in catchment that doesn’t come into contact with disturbed land

will be released in a controlled manner to the river system

• Rain water falling on area disturbed by mining activity will be captured in dams
• This water will be re-used as process water
• Use of this water will be off-set with fresh water
• Areas within the catchment dam footprint is considered as disturbed land

Water Management

14

Groundwater - Monitoring

15

Groundwater - Sourcing

16

• Ground water will be used to supplement water

requirements

• Sourced from the Lower Aquifer (Latrobe Group)
• Impact of extraction has been modelled for 15 years

at 3 GL per annum

• Assessed a large area in the EES for bore field
• Cultural Heritage
• Biodiversity
• Boreholes will disturb a small area of land
• Groundwater from bore will be piped to process

Logistics

Rail Sidings - Fernbank

21

• Siding located close to project area on private land
• Will utilise a private haulage road from project area
• Haulage road aligned with power and water services corridor
• Option included in the EES assessments
• Traffic
• Cultural heritage
• Biodiversity
• Noise and vibration
• Visual
• Air quality
• Socioeconomic

Rail Siding - Bairnsdale

22

• An alternative option is to use the existing siding in Bairnsdale
• Concentrate will still be loaded into containers at the mine site
• Containers will be trucked to Bairnsdale via Lindenow South (see map below)
• Proposed route will avoid traffic along main road in Bairnsdale
• Intersection on Princes Highway will be upgraded
• Trucks directed around race course to siding
• Siding located near Fennings yard will need to be upgraded
• Option included in the EES assessments
• e.g. traffic, cultural heritage, biodiversity and socioeconomic
