The Hillside PEPR is the key operational document against which Rex must demonstrate and report compliance. Annual compliance reports will be published on the DEM website. Authorised DEM officers will conduct compliance inspections to ensure operations are undertaken in accordance with the PEPR and lease and licence conditions.

Before starting operations, the Hillside mining lease conditions require Rex to establish real-time monitoring and public reporting frameworks for air quality and noise. Rex will establish an online public portal to display this real-time information.

Before starting construction or mining operations, Rex must pay a $34 million rehabilitation bond which DEM will hold as security to ensure land rehabilitation obligations can be satisfied. It is important to note the bond does not negate the requirement for a tenement holder to meet their legal obligations under the Mining Act relating to rehabilitation of disturbed land.
