BUSINESS OVERVIEW – QUICK FACTS

• Mine started in 1999. Full Investment Proposal (IP)

production was reached in 2003 at 220ktpm.

• Life of Mine at current mining rates is until 2028.

• The mine applies a fully mechanised bord and pillar mining

method.

• Consists of two decline shafts namely East and Central

shafts.

• Low Profile mining between 195cm and 220cm stope width

delivers 90% of total tonnage.

• Extra Low Profile mining at 120cm stope width delivers the

remaining 10% of tonnage.

• Ultra Low Profile mining at 100cm stope width currently in

project phase.

• Approximately 31% and 22% of total Rustenburg tonnage

and platinum ounce production respectively are produced by

Bathopele.

LAMP ROOM MANAGEMENT

12

INNOVATION BUSINESS IMPROVEMENT

Detail – Cap lamp warning system

Lamp room management

• Ensures every U/G employee is

issued with a lamp, and assists with

shift clearance

• Messaging function

• Automatic Download of data

• Tracking function.

• Enhanced light & sound warning

function

13

PHASE I – LAMP ROOM MANAGEMENT

Required safety equipment will be

allocated to the person at the Auto

Allocation Bay

Safety Equipment Allocated?

No

Yes

CAS Test Unit

Lamp has LCD screen enabling PTC messaging (both directions) as well as distress call

Frames will block underground access if person not carrying all required allocated

safety equipment

ASSET TRACKING

15

PHASE II – IM INFRASTRUCTURE

Underground network: − Central and East Shafts − Declines and all active

strikes − Redundancy link

Underground network: − network enclosures installed every 200m in all

active strikes – hosts Schauenburg controllers which provide approximately 100m radius line-of-sight RFI coverage

− will be monitored 24/7 by IIT − will host all systems requiring underground

network connectivity − is “expansion ready” for any future requirements

16

PHASE I – PEOPLE TRACKING

Surface and

Underground

Antennas

and

Controllers

use RFI to

track assets

Surface Asset Tracking

Underground Asset Tracking

PTC Messaging (both directions) and Distress Call

COLLISION WARNING SYSTEM

LEGAL ASPECTS TMM • Implementation drive from DMR– Regulation

• 8.10.1.2 All underground diesel powered trackless mobile machines must be provided with means:

• 8.10.1.2(a) to automatically detect the presence of any pedestrian within its vicinity. Upon detecting the presence of a pedestrian, the operator of the diesel powered trackless mobile machine and the pedestrian shall be warned of each other’s presence by means of an effective warning; and

• 8.10.1.2(b) in the event where no action is taken to prevent potential collision, further means shall be provided to retard the diesel powered trackless mobile machine to a safe speed where after the brakes of the diesel powered trackless mobile machine are automatically applied. The system on the diesel powered trackless mobile machine must fail to safe without human intervention.

The regulations, except sub-regulations 8.10.1.2(b) and 8.10.2.1(b), will come into force 3 months after the date of publication;

A further notice will be published at some time in the future to indicate when sub-regulations 8.10.1.2(b) and 8.10.2.1(b) will come into force;

The requirement to have PDS systems applies only in respect of: (i) mines where there is a significant risk of pedestrians being injured as a result of collisions between TMMs and pedestrians and (ii) opencast and open pit mines where there is a significant risk of injury as a result of collisions between diesel TMMs. It will therefore be important for mines to do proper risk assessments and have copies of them available at the mine to substantiate any decision as to whether or not PDS systems are required at the mine in terms of the regulations.

PDS/VDS/CAS

• Persons U/G are warned of

approaching vehicles.

• Vehicle operators are warned

of pedestrians.

• Vehicles are warned of other

vehicles.

• Vehicles are slowed down

and/or stopped automatically

within certain zones.

25


PDS / CAS JOURNEY

• URS were drafted during 2012 and final approval of the project was in Nov 2013

• 2014 Development/Testing of technology

• During integration tests interference issues were picked up

• The mine requested vendors to conduct extensive independent tests at ITC and GEROTEK

• Vendor solutions was also piloted underground to verify the outcome of the independent tests

• The pilot results supported the independent test results
