1 Current Mining Status

1.1 Longwall

Longwall 23 commenced in October 2017 and is planned to finish by late February this year. Longwall 24 is then planned to commence operation in mid to late March and extract coal over the next four months, completing extraction during July 2018. Longwall 24 start position is located just to north-west of Tobins Rd as shown in Figure 1. Figure 1 - Mine Plan and Surface Features.

1.2 Development

Maingate 24 has almost completed development for Longwall 24, while Maingate 24A and Tailgate 25 have progressed to approximately half their planned length. The Main Headings have advanced and recently completed the roadways for the commencement of Maingate 25 as shown in Figure 1.

2 Exploration

Surface borehole exploration is in progress within Olney State Forest and is focusing on defining the location the sill near the end of Longwalls 25 to 29. Two boreholes have been completed in this area and another three are planned.

3 Environmental Monitoring

Environmental monitoring has continued at Mandalong, Mandalong South, Cooranbong and Delta as required by the Environmental Protection Licence (EPL 365) and Development Consents DA 97/800, SSD-5144 and SSD-5145. A summary and review of the monitoring results will be presented at the CCC meeting.

4 Planning Approvals

4.1 Mandalong Southern Extension Project

The access road and pads for the ventilation shafts have been completed and Daracon has demobilised from site. The Mandalong Road pavement has continued to be monitored during the period with no reports made to LMCC since the last meeting. The tender for the ventilation shafts commenced in December 2017 and closes 14 February 2018. It is expected that site works for the shafts will commence in May 2018.

4.2 TransGrid TL24 Relocation Project

TransGrid’s Principal Contractor, Zinfra, have been working on site since November 2017 and the program is on schedule. There are eight new tower sites which are all in progress at one of the following stages:

• Excavation;
• Formwork;
• Pouring of concrete;
• Stripping of formwork;
• Tower assembly;
• Tower erection; and
• Rehabilitation of construction pad.

The construction of the new towers is scheduled to be completed in May 2018. Once the towers are constructed Zinfra will commence the stringing works which will require use of a helicopter at low

• height. Dates for the helicopter are not yet available, but it is expected that it will be on site for six
• days. Centennial Mandalong will notify nearby residents when the helicopter dates are known.

Once the new line is operational, there are twelve towers which will be decommissioned and removed and the redundant easement will be relinquished by TransGrid to the landowners. The decommissioning and removal is expected to take place from June 2018 and take approximately two months.

4.3 33 kV Powerline to MSSS

Downer Engineering is still completing its design of the power line route and associated easement and clearing required. A number of options had to be considered where the line crosses existing

• infrastructure. A final design is expected very soon.

Ecology surveys continued in November and December, as did geotechnical drilling for the pole sites. A heritage survey is planned for April and the RAPs have been informed and are reviewing the heritage methodology. All other assessments will commence as soon as the final design is confirmed.

4.4 TransGrid TL24 Mitigation Works

Mitigation works to retrofit concrete cruciform footings on TL24 Towers 45, 46 and 47 located over Longwalls 22 to 24A was completed in July 2017. Towers 47 and 46 have now been mined beneath by Longwalls 23 and 24 respectively. Subsidence monitoring has been undertaken in accordance

12 | P a g e

Mandalong Mine CCC Pre-Meeting Report – February 2018

with the approved TransGrid Tower Management Plan and has shown subsidence to be well within the predicted values, with no impact to the two towers observed.

4.5 Cooranbong Modification 1

The Centennial Northern Coal Services modification (SSD-5145 Mod 1) was approved by the Department of Planning & Environment on 25 January 2018. The modification allows Northern Coal Services to:

• Increase the number of full-time equivalent (FTE) employees based at the Cooranbong Entry

Site from 14 to 60; and

• Amend the operational noise criteria specified by Condition 2 of Schedule 3 for the privately-
• wned residences in the vicinity of the Cooranbong Entry Site.

5 Community Contacts

5.1 Mandalong 5.1.1 Mining Notifications

One month mining notifications for Longwalls 23 and 24 have been provided to landowners, Centennial tenants and infrastructure owners prior to mining beneath their property or asset as per PSMPs and Infrastructure Management Plans.

5.1.2 Consultation

Consultation is ongoing with landowners and infrastructure owners affected by current operations for LW22-23 and the recently approved Extraction Plan for LW24-24A.

5.2 Mandalong South

Various contacts with land holders regarding the commencement of the MSSS Access Road construction and quarterly noise monitoring occurred at the end of December 2017.

5.3 Complaints

There were no community complaints received since the October 2017 meeting.

5.4 Sponsorship

• 1. Wangi Fire Brigade;
• 2. MCA Christmas Party;
• 3. LMCC School Environment Awards; and
• 4. Morisset 2018 Show.
