1 Current Mining Status

1.1 Longwall

Longwall 19 completed extraction on 24 May 2016. The longwall equipment is currently being moved to Longwall 20, which is due to commence extraction in mid-June. Figure 1 shows the completed Longwall 19, the start position of Longwall 20 and the proposed development roadways for Longwalls 21 to 24A which are limited to the north-west by the thickness igneous sill shown by the hatch pattern.

Figure 1 - Mine Plan up to LW24A and showing the extent of the igneous sill.

1.2 Development

Maingate 20 advanced approximately 550m into the area intruded by the igneous sill, terminating approximately 500m short of its planned length, at a position where the minimum available seam thickness and coal quality has been reached. Maingate 21 has developed over half its planned length and will finish in a similar position to Maingate 20. Maingate 22 recently commenced development.

The Main Headings have continued to advance south of Chapman Rd and development within the Mandalong South Mining Lease (ML1722) as shown in Figure 1 above.

2 Exploration Surface exploration drilling primarily targeted at defining the extent of the igneous sill for the proposed Longwalls 22 to 24A recommenced at the end of May. The three borehole sites are located off Little Valley Road and along the edge of the proposed Longwall 24A.

3 Environmental Monitoring Environmental monitoring has continued at Mandalong, Cooranbong and Delta as required by the Environmental Protection Licence (EPL 365) and Development Consents DA 97/800 (MOD10), SSD-5144 and SSD-5145. A summary and review of the monitoring results will be presented at the CCC meeting.

3.1 Air Quality Monitoring

3.2 Surface Water Quality Monitoring Update

The following parameters, pH, Total Suspended Solids (TSS mg/L), Electrical Conductivity (EC µs/cm) and Oil and Grease (mg/L) are monitored at Licenced Discharge Point LDP001 and LDP002 daily during discharge in accordance with the requirements of Environmental Protection Licence 365. Table 2 and Table 3 show a summary of these results, whilst Figure 3 to Figure 5 are graphical representations. Additional pollutants are required to be monitored monthly during discharge; these results can be found in Table 4.

4 Planning Approvals

4.1 Mandalong Southern Extension Project

The proposed intersection on Mandalong Road with the Access Road has been relocated approximately 80 m north due to LMCC requiring the crest to be removed on the existing section of road at the original location. This would have required extensive additional construction work and the removal of additional trees in front of a resident’s property. As such a new design has been submitted to LMCC for a Construction Certificate. The project team has been assisting with updating and developing environmental management plans as required by the Development Consent SSD-5144. Sub-surface heritage works was undertaken in line with commitments made in the EIS and Schedule 3 Condition 21 of SSD-5144. No artefacts were found in the three target areas.

4.2 TransGrid TL24 Relocation

The Statement of Environmental Effects and supporting technical specialist assessments were placed on public exhibition by the Department of Planning and Environment from 22 April 2016 to 6 May 2016. Five government agency submissions and two public submissions were received. A formal response to matters raised was requested by the Department of Planning and Environment (DP&E) in correspondence dated 12 May 2016. Additional matters requiring clarification were raised by DP&E in the same correspondence. On 24 May 2016 a Response to Submissions Letter Report was submitted to DP&E which provided Centennial Mandalong’s response to submission matters in addition to the additional DP&E matters requiring clarification. It is expected that TransGrid will start work on the powerline in the second quarter of 2017.

4.3 Production Tonnage Increase

Centennial Mandalong is seeking to modify its existing development consent for the Mandalong Production Tonnage Project. The Project is seeking an increase in the annual production limit from 6 million tonnes per annum to 6.5 million tonnes per annum of ROM coal. This increase is required due to the mine optimising the production process, both in terms of mechanical improvements and through the continuing development and training of underground operators. Thermal coal will continue to be extracted from the West Wallarah and Wallarah Great Northern Seams in accordance with the mine layout and extraction methods approved under SSD-5144 within the current mining lease areas.

Schedule 2, Condition 7 of SSD-5144 currently permits the following: In any calendar year, the Applicant shall not: a) Extract more than 6 million tonnes of ROM coal from the site; b) Deliver more than 6 million tonnes of ROM coal to the Cooranbong Entry Site; and/or c) Deliver more than 6 million tonnes of ROM coal to the Mandalong Coal Delivery System. The increase will not affect the delivery limits associated with the Cooranbong Entry Site and the Mandalong Coal Delivery System. No physical changes to the mine’s infrastructure or the surface footprint as currently approved under SSD-5144 are proposed.

5 Community Contacts

5.1 Mandalong

5.1.1 Mining Notifications

One month mining notifications for Longwall 19 and Longwall 20 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 was ongoing with landowners and infrastructure owners affected by current operations for and for the development of the Extraction Plan for LW22-24 and individual Property Subsidence Management Plans. Mandalong Mine received two requests for mining information from prospective purchasers of private property in Mandalong. This included information on current and proposed mining status, subsidence and flooding.

5.2 Mandalong South

The draft Construction Traffic Management Sub-plan was placed on the Centennial Coal website in March and residents that receive the Mandalong Mailbox were offered the opportunity to make comment on the plan. During the four week consultation period 5 community submissions were received. An additional 6 were received after the period, but have all been considered in the revision of the management plan. Many valid points have been made by the community to improve the document. The revised plan was forwarded to the DP&E and they have asked Centennial to address some additional points. This is currently in progress.

5.3 Complaints

There were no community complaints received since the February 2016 meeting.

5.4 Sponsorship

1. Cooranbong Community Preschool; 2. Cooranbong Public School – Annual Family Fun Afternoon – December 2016; and 3. Avondale School Family Festival – September 2016.

6 Land Management

6.1 Mandalong Properties

An update of the Summary of Proposed Land Management Activities for period ending April 2016 is included in Appendix 1. The Activities table has been configured so properties will be displayed consecutively in street address order. Note that work that has been commenced or completed appears in blue text. Also, works to eradicate tobacco bush adjacent to Morans Creek have continued over the last few months.

6.2 Property Sale

Centennial recently sold a property in Walls Lane and are currently finalising preparations for the sale of another property at Mandalong. The recent property review for Mandalong means sales in this locality will continue over the coming years.
