3. Background Dion Hurn, Haulage Supervisor, Mining, August 22, 2011 Slide 3 Underground Teleremote Operation  Previously in place at Cannington Mine.  Operator was 200 – 300 metres from operating machinery.  Operator was still underground and exposed to hazards.

4. The Initiative Dion Hurn, Haulage Supervisor, Mining, August 22, 2011 Slide 4 The Projects Team began discussing the possibility of building on the existing site Teleremote Capabilities. Major step in protecting employee health and increasing safety.

5. The Solution Dion Hurn, Haulage Supervisor, Mining, August 22, 2011 Slide 5 Initial investigations  An external organisation was consulted.  The vendor was provided with concerns and requirements for development of a Surface Teleremote Operation.

6. The Solution Dion Hurn, Haulage Supervisor, Mining, August 22, 2011 Slide 6 Implementation  Phase 1 - underground loaders were operated from the surface mining administration building.  Phase 2 - introduction of a guidance system.

7. The Solution Dion Hurn, Haulage Supervisor, Mining, August 22, 2011 Slide 7 The Surface Teleremote Operator was developed with:  a wireless control system  distributed antenna infrastructure. The system includes a power supply health monitoring circuit with a battery back up.
