Waste<br />

Our mine sites operate within the framework of a comprehensive waste management system which involves<br />

handling and management of all kinds of day-to-day and industrial waste streams. In 2015, the total amount of<br />

solid waste generated from the mine site activities was reduced by 44.7% compared to 2014.<br />

Solid waste, m 3 12,261 6,768.7<br />

Proportion recycled, % 68 60<br />

The Company continues to operate a small scale waste recycling facility established in 2013 where scrap<br />

materials are used in making products such as garbage bins, metal fences, sliding doors, wooden benches,<br />

blocks, insect protection nets and horse rugs.<br />

Hazardous non-mineral waste is delivered back to the suppliers for re-use or appropriate disposal. Plastic waste,<br />

waste metal and waste paper are sent to designated recycling facilities in other provinces. Printer cartridges<br />

are sent back to suppliers for refill and reuse. Collecting and recycling used oil is crucial for preventing oil<br />

contamination to soil and groundwater. Used oil is collected in a dedicated tank, prior to be being sent to a<br />

recycling facility which produces fuel and other raw materials.<br />

Air quality and noise<br />

Dust and air quality are significant issues for our neighbouring communities, and minimising the effects of these<br />

impacts from our operations will remain a key focus for us. For the reporting period, the Company continued to<br />

take appropriate measures to reduce the amount of dust generated in the vicinity of the mine site and the coal<br />

haul road in accordance with the dust management plan of the project environmental and social management<br />

plan. These measures include:<br />

• Regular spraying of the haulage roads at the mine site with treated waste water;<br />

• Improved construction methodology of mine haulage roads, in particular using carefully selected materials,<br />

to reduce propensity for dust generation;<br />

• Trial usage of two types of dust suppressing substances on the surface of the TSF;<br />

• Usage of various substances for dust suppression on the ROM coal haul roads;<br />

• Building and maintenance of dedicated facilities for dust reduction, such as a 10-metre high special wire<br />

fence which surrounds our coal stockpile at TKH. These and other similar facilities reduce wind speed and<br />

dust dispersion in the area;<br />

• Better management of vehicle speeds; and<br />

• Covering of truck loads.<br />
