Gold Fields Modernisation

Digital Mine Operations Overview

Michael Place | June 2024

Gold Fields Modernisation Vision

Our focus is to modernise our operations & how we work

Address one of Gold Fields' key Strategy

initiatives: prioritise fit for purpose modernisation & innovation opportunities, adding value across the business

Commitment to lock in the next 3 - 5-year roadmap modernisation of our operations

Value Proposition: why is this important to GFA?

SAFETY: Removing our people from high-risk environments

UTILISATION: Real-time visibility of our mining operations Increasing productivity, reducing variability & operating costs

DECARBONISATION: Emission reduction & zero emission material movement

Gold Fields Modernisation Roadmap

3 Horizon approach

Horizon 1 - Modernise & Visualise

Enabling technologies to modernise GFA assets and provide the building blocks for future Horizon 2 & 3 systems

• Surface & underground digital wireless communication
• Location tracking
• Machine sensors & telemetry
• Digital tablet applications

H1H2

H3

Horizon 2 - Integrate & Optimise

Integrated operating systems providing visualisation on operations and equipment

• Integrated mine operation systems
• Fleet Management Systems
• Mobile equipment remote control & semi- automation programs

Horizon 3 - Autonomous and Zero Emissions

Technologies and systems to deliver automated operational decision making across the mine value

Modernisation aims to:

-	improve safety	-	support asset optimisation
-	enable future workforce	-	create a culture of innovation
-	drive productivity efficiencies	-	collaborate with key stakeholders
-	reduce variability	-	standardise systems and processes

chain

• Automated equipment operation mine - mill
• Zero emission production
• Digital twin and machine learning
• Data analytics & optimisation

Gold Fields Mine Operating System Horizons

Horizon 1: Connect

Network Backbone

Communication Backbone providing

wireless connectivity throughout the mine to all mobile and fixed equipment enabling location tracking of mobile equipment in surface and underground

Horizon 2: Integrate

Mine Operating System

Mine Operating Centre with full

visualisation of the mine, enabling Short Interval Control of the mine using short term & daily shift scheduling integrated with fleet dispatch, operational data capture and material management systems

Horizon 3: Optimise

Mine Control

Automated operational data capture,

fleet dispatch and Short Interval Control.

Data Analytics running simulations and optimising the Mine Operating Systems

Automated Data Recording and Visibility

• Very High % of automated recording of data by FMS
• Time saved can spent more optimally controlling fleet.
• Very limited exposure of manual entry errors
• No double handling of data

2	Automated Data Communication

Controller

ABB OMS

• Automated communication of data - less reliance on voice comms
• Less prone to data errors
• Less prone to missing data

1	Automated Data Capture

• Alignment of how actuals are captured across fleet.
• Accurate time stamped data
• High % of automated data capture
• Richer data sets captured and in context to vehicles activity
