8. Our Journey to Automation:
First trial in SW quadrant of Lift 1 mine
Design of compliant barrier systems
Second production trial at Lift 2 mine
E48 Project commences construction
E48 Project scope varied to
include autonomous LHDs
Full implementation of autonomous loaders on
E48 Production level commenced
100% automated LHD Production on E48
Extraction level commenced October 2015

Are we there yet?
23.2Mt in 4 years!

9. LHD Automation:
1999 2005 2011 2015
Mobile Fleet Automation (MFA) at Northparkes has been driven by people who are
passionate about;
1. Increasing Operator Safety
2. Increasing the Efficiency of our Production Operations
3. Lowering the Costs of our Production Operations
4. Providing NPM with a Long Term Solution to deliver Value as our ore grades
become Lower and Harder to Extract.

10. LHD Automation:
1999 2005 2011 2015
Normalised Auto Production 101% Of Hourly Manual Rate
Auto LHDs have higher hourly production rates
Auto LHD Production 123% Of Daily Manual Tonnes Per LHD
Higher daily production
Auto LHD Production 76% of Manual Cost Per Tonne
At Lower Cost

11. LHD Automation:
1999 2005 2011 2015
1. Significant change must have a process
2. The vision was set, the teams were well informed and an integral part of the future
3. The journey had been significant before and the prize was within reach
4. All risk assessments and actions checked and closed out
5. Systems checked and double checked
6. Testing and staged approach through each commissioning phase
7. Full execution and integration across the Block cave footprint
8. At every stage people were engaged and actively involved not threatened

12. LHD Automation:
1999 2005 2011 2015
Level of System Maturity
• Length of time system has been in use
• Number of sites system has been in use
• Availability of staff with depth of
experience with the system
• Built in redundancy (additional capacity)
• Diagnostic Tools
• Support capacity of OEM
• Coverage
• Skill level
• Availability of parts
• Level of documentation
• Compliance to standards / regulator

13. Projects “Ventilation Shafts”
• Automation allowed for the
compliance to a 195 Prohibition Notice
• Automation enabled successful
bogging of the 2 shafts
• Automation separated people from the
Raise Bore hazards

14. Our Future Innovation:
Working with Orica to optimise wireless detonation systems and products for the SLC and
“High Lift Drawbells” in the Block Cave.
Working with LDO to implement technology and systems for Dust reduction in return airways
for safer working environments.
Working with Mining OEM’s and watching the Battery space for Underground Load Haul
Machines and other vehicles . We are taking a wait and see approach because we have not
set our roadmap on battery technology.
Always evaluating the next application of technology into mining, how does it work for your
operation.
What is the next “Burning Platform”.
