Overview
This FAQ addresses common questions about the autonomous haulage trial currently underway at our Pilbara East operation. The trial, which commenced in January 2024, involves three Caterpillar 794 AC autonomous haul trucks operating on a dedicated circuit between the North Pit and the primary crusher.

General Questions
Q: What exactly is autonomous haulage?
A: Autonomous haulage uses self-driving trucks equipped with GPS, radar, LiDAR, and AI systems to transport material without human operators in the cab. Our three Cat 794s can carry 290 tonnes each and operate 24/7 with remote supervision from our upgraded control room.
Q: Why is IronVale trialling this technology?
A: Chief Operating Officer Karen Whitfield identified autonomous haulage as a key opportunity to improve safety, reduce operating costs, and maintain competitiveness. The trial allows us to evaluate the technology's performance in our specific conditions before considering broader deployment.
Q: How long will the trial run?
A: The initial trial period is 18 months, running through June 2025. Based on performance metrics and safety outcomes, we'll decide whether to expand autonomous operations or return to conventional haulage on this circuit.
Technology & Operations
Q: How do the autonomous trucks navigate?
A: Each truck uses a combination of: - High-precision GPS (accurate to within 10cm) - Multiple radar and LiDAR sensors - Real-time mapping technology - Machine-to-machine communication - Integration with our existing fleet management system
The trucks follow pre-programmed routes but can make real-time adjustments for obstacles, weather conditions, or traffic management.
Q: What happens if something goes wrong?
A: Multiple safety systems are in place: - Remote operators in the control room can take immediate control - Trucks automatically stop if they detect unexpected obstacles - All autonomous vehicles operate on a segregated circuit away from personnel - Emergency stop capabilities are distributed throughout the operation area - 24/7 monitoring by qualified operators
Q: Can the trucks operate in all weather conditions?
A: Currently, the autonomous trucks are suspended during: - Heavy rainfall (>15mm/hour) - Dust storms with visibility below 100 metres - Electrical storms within 10km radius - High winds (>45 km/h sustained)
We're working with Caterpillar to expand the operational envelope as the trial progresses.
Q: How do they interact with our conventional fleet?
A: The autonomous trucks operate on a dedicated circuit with minimal interaction with conventional equipment. When interaction is necessary, traffic management protocols ensure safe separation. All conventional operators have received briefings on autonomous truck behaviour and emergency procedures.
Safety Questions
Q: Is autonomous haulage safer than conventional trucks?
A: Preliminary data suggests autonomous trucks eliminate human error factors (fatigue, distraction, health events), which account for approximately 70% of haul truck incidents industry-wide. However, we're still evaluating long-term safety performance against our conventional fleet baseline.
Q: What safety training has been provided?
A: All Pilbara East personnel completed mandatory autonomous vehicle awareness training in December 2023. Specific training modules covered: - Recognition of autonomous vehicles - Safe interaction protocols - Emergency procedures - Communication protocols
Refresher training is scheduled quarterly, with the next session in June 2024.
Q: Who's responsible if an autonomous truck has an incident?
A: IronVale maintains full responsibility for all autonomous vehicle operations. Our insurance coverage has been updated to include autonomous technology, and incident investigation protocols have been revised accordingly. Health, Safety & Emergency Manager Brooke Lawson leads all autonomous-related safety reviews.
Q: Can people still work near the autonomous trucks?
A: The autonomous circuit is designated as a restricted area during operational hours (currently 6 AM to 10 PM). Personnel access requires prior approval from the Site Manager and adherence to specific safety protocols. Maintenance activities follow lockout/tagout procedures adapted for autonomous systems.
Workforce Impact
Q: Will autonomous trucks replace jobs at IronVale?
A: The current trial involves no job losses. Three truck operators have been redeployed to other roles within Pilbara East, including equipment maintenance and pit operations. Any future decisions about autonomous expansion will be made in consultation with our workforce and union representatives.
Q: What new jobs does autonomous haulage create?
A: New roles include: - Autonomous systems operator (control room) - Technology support specialist - Data analyst (fleet performance) - Remote systems technician
We're currently training existing employees for these positions rather than external recruitment.
Q: How does this affect FIFO schedules?
A: Current FIFO rosters remain unchanged. The control room operators follow standard 2-week on, 1-week off rotations. Some maintenance specialists may require extended swings for system updates, but this impacts fewer than 10 personnel.
Q: Will this change union agreements?
A: We're in ongoing discussions with the Australian Workers' Union regarding autonomous technology provisions. Current enterprise agreements remain in effect, and any changes will be negotiated in good faith. Head of People & Community Danielle Keenan coordinates these discussions.
Performance & Economics
Q: How much does autonomous haulage cost?
A: The trial represents a $12M investment including equipment modification, infrastructure upgrades, and training. Operating cost comparisons are preliminary, but early data suggests 15-20% reduction in cost per tonne hauled, primarily through improved utilisation and reduced maintenance.
Q: What's the productivity impact?
A: Autonomous trucks achieve approximately 85% utilisation versus 65% for conventional trucks during operational hours. However, they currently operate fewer hours due to weather restrictions. Overall circuit capacity has increased by 8% since trial commencement.
Q: How reliable has the technology been?
A: As of March 2024: - System availability: 92% - Unplanned downtime: 6% (primarily software updates) - Mean time between failures: 240 hours - Remote intervention frequency: 1.2 times per 12-hour shift
These figures are improving as the system learns our operational patterns.
Future Plans
Q: Will autonomous haulage expand to other areas?
A: Expansion depends on trial outcomes and business case development. Potential applications include the South Pit circuit and our planned lithium operation in the Goldfields. No firm decisions have been made.
Q: When will we know if the trial is successful?
A: Comprehensive evaluation occurs at 6-month intervals. The next major review is scheduled for July 2024, with final recommendations to the Board by December 2024.
Q: How does this fit with IronVale's sustainability goals?
A: Autonomous trucks support our environmental commitments through: - Optimised routing reducing fuel consumption - Improved maintenance scheduling - Potential for electric autonomous vehicles in future - Data-driven efficiency improvements
Dr. Ravi Mehta, our General Manager of Sustainability & Environment, includes autonomous haulage benefits in our annual ESG reporting.
Technical Support
Q: Who maintains the autonomous trucks?
A: Caterpillar provides Level 3 technical support under our service agreement. Our maintenance team handles routine servicing with additional training on autonomous-specific systems. Complex software issues escalate to Caterpillar's remote support centre in Illinois.
Q: What about cybersecurity?
A: All autonomous systems operate on isolated networks with multiple security layers. Regular penetration testing occurs quarterly, and we maintain cyber insurance specific to industrial control systems. IT security protocols align with mining industry best practices.
Q: How often is the software updated?
A: Major software updates occur monthly during planned maintenance windows. Critical safety updates can be deployed remotely within 4 hours if required. All updates require Site Manager approval and safety review.
For additional questions or concerns, contact Pete Drummond at ext. 2200 or submit feedback through the IronVale Connect portal. This document is updated monthly based on operational experience and stakeholder feedback.
