Newstan on Care & Maintenance

Continued with care and maintenance activities, focused on maintaining the mine infrastructure and keeping the mine safe.

• Three underground employees working full time.

– Focus on underground roof support maintenance. – Repairing roads. – Maintaining and improving dewatering infrastructure. – Improving the quality of goaf seals.

Newstan Mine Extension Project

March 2019 – August 2019

Project Overview

3

• Newstan Extension Project is seeking approval for:

– Bord and pillar mining using combination of first workings, partial and total extraction – Extraction of up to 4 Mtpa over a 15 year mine life. – In-seam gas drainage with captured gas transferred to a gas flaring facility at the Awaba Colliery Surface Site – Men and materials access from the Newstan Colliery Surface site – Utilisation of ventilation shafts at the Newstan Colliery Surface Site and Awaba Colliery Surface Site – Operational workforce of up to 320 personnel – Peak construction workforce of up to 50 personnel

Note operational implementation may result in less than approved limits identified above

Project Area

14

Significant resources remain to the south and east of our proposed mining area

Mine Design

1

• Project balances optimising resource recovery and protecting sensitive

environmental features

• The combination of first workings, partial extraction, and total

extraction adopted to minimise subsidence impacts enabling adaptive management strategies to be implemented as mining progresses

• First working zones mitigate multi-seam subsidence impacts

associated with the Awaba workings in the overlying Great Northern seam

Mining Zones

16

Surface Infrastructure

1

• All new proposed surface infrastructure will be located at the Awaba

Colliery Surface Site

• Minimal vegetation clearing is required which will reduce any

biodiversity offset costs

• The Awaba Colliery Surface Site is ideally situated above the

proposed mining area and close to existing ventilation infrastructure

Environmental Assessments

6

• Baseline surveys commenced to confirm what exists across the project

area and determine the condition

• Technical Impact Assessments commenced to address:

– Subsidence – Groundwater and surface water – Terrestrial and aquatic ecology – Air quality and greenhouse gas – Noise and vibration – Traffic and transport – Aboriginal and historic heritage – Visual – Socio-economic

Environmental Impact Statement

7

• As part of the preparation of impact assessments, environmental

mitigation, management, monitoring and offset measures will be identified to enhance the project’s benefits and address any impacts

• All the findings will be documented in the EIS
• EIS submission targeting Q1 2020

Newstan Environment & Community Update

March 2019 – August 2019

Newstan Environmental Monitoring

• There was one exceedance of water quality criteria for the reporting
• period. LDP1 recorded a bicarbonate alkalinity measurement of 750mg/l

(limit of 711mg/l).

• The Average Annual results for Dust gauges at Newstan were less than

4.0 g/m2/month during the reporting period.

• The Total Particulate Matter (TSP) and PM10 results were within

Development Consent criteria during the reporting period.

• Quarterly Noise Monitoring was carried out in March and June 2019.

There were no exceedances of the Development Consent noise limit criteria.

23

Summary of Compliance

• There were no other exceedances or non-compliance since the last

meeting.

• There were no complaints received since the last meeting.
• Newstan received two Penalty Infringement Notices (PIN’s) in

relation to noise exceedances in Q2 2018.

– 1 x PIN received for exceedance of noise criteria – 1 x PIN received for the real time noise monitor not providing consistently reliable results

• Newstan is progressing the installation of the new Sentinex Noise

Unit to ensure compliance with the Development Consent requirements.

24

Southern Rejects Emplacement Area

• Recent attention locally and globally on the stability / safety of dams

holding fine rejects.

• Centennial wishes to engage proactively with community about the

facilities we operate

• The SREA is used to receive reject material from the processing of

coal from Centennial’s Mandalong mine

• Rejects can be coarse or fine and must be disposed of as part of a

reject management plan. This occurs under strict environmental conditions and subject to various planning and environmental

• approvals. Fine, wet rejects is often referred to as tailings, as is
• ften stored in a tailings dam.
• The current lifespan on the SREA is approximately between 15 – 20

years and will be capped and rehabilitated to natural landform once it reaches its maximum design capacity.

25

Southern Rejects Emplacement Area

• The previous Northern reject emplacement area is an example of the

effective management of tailings. The area is being filled and progressively shaped, capped and revegetated to a natural state.

• The SREA was designed to provide long-term stable storage for tailings

and course reject from Centennial’s Lake Macquarie operations. It was designed by external consultants who have particular expertise in the design and management of reject storage facilities.

26

Photos of SREA from Dave Baker to be included in this slide and the following slide.

SREA - Technical

• The SREA is subject to the strictest environmental and auditing processes

meeting all government requirements.

• Inspections are carried out daily along with external expert engineers who

regularly inspect the SREA to ensure the site is managed safely and all regulatory conditions are met.

• Aerial surveys of the SREA are conducted using LiDAR technology to

monitor and identify any changes to the dam wall and surrounds.

27

SREA – is safe

• The SREA was designed to provide long-term storage for

tailings and coarse reject from Centennial’s Lake Macquarie operations. Reject has been managed at the Newstan site since 1950’s, nearly 70 years ago.

• The dam is a ‘prescribed dam’ pursuant to the Dam Safety

Act (NSW), and as such, is subject to additional external scrutiny and audit by regulators.

Newstan Pumped Hydro Storage Project CCC Update

File Name: Banpu Introduction to CMPHES

15 August 2019

Why does the NSW Government want pumped hydro?

Where does Pumped Storage fit in

Source:

What is Pumped Hydro

32

• It is using water as a battery
• If water is stored in a dam at

the top of a hill it can store energy

• On releasing that water, it can

be passed through a turbine to produce electricity

• If the water is then captured in

a dam at the bottom of the hill, it can be pumped back up the hill again to create stored energy for use at a later time

• This concept is called pumped

hydro energy storage (PHES)

NSW future energy generation and transmission

Pumped Storage 9GW

What is Newstan Colliery proposing - CMPHES

34

• Coal Mine Pumped Hydro Energy Storage (CMPHES)
• Underground pumped hydro system
• Utilising existing voids in the previously mined areas
• Moving water between these voids to use / generate

electricity

What is the current status, next steps and timing Current status

• Newstan has applied to the NSW Emerging Energy

Program (NSW EEP) for funding to assist progress the concept of an 8.5 MW Coal Mine Pumped Hydro Energy Storage System (CMPHES)

• The NSW EEP aims to support renewable energy

initiatives to support an orderly transition to a clean, reliable and affordable energy future.

• In July 2019, the Newstan project advanced to Stage 2
• It was one of 21 successful submissions across 6 different

Renewable Energy technologies

• Stage 2 submissions close end of September 2019

What is the current status, next steps and timing Next Steps and timing

• The Newstan project is still at Concept Stage
• Funding success would allow detailed engineering and

financial feasibility assessment

• Environmental Assessments to support a Planning

Approval application would commence including formal consultation with relevant stakeholders

• This process will likely take 2 years
