SAFETY

We are making progress : A reduction in fatality rate (FR) and Lost Time Injury Frequency Rate FR = 0.03 (Last year 0.04) LTIFR = 2.95 (3.75) Target 2002 =1.4 Rates compare favourably to platinum and gold industry. Behavioural based safety / continuous business Improvement. Mechanisation (quantum improvement)

RUSTENBURG SECTION

A good operational year – cost increase / Pt oz refined– 2.0% Expansion phase – despite Merensky slow depletion Exploit the shallow massive UG2 reserve Take current production from 1.123m oz (4E) to ±1.5moz (4E) Restructured management, greater focus and accountability Reduce and dilute fixed central costs and maintain a good cost performance Infrastructure investment (shafts, haulages, rolling stock etc) Mechanisation – productivity/costs (it’s working i.e. labour as total % of cost is decreasing)

WORLD CLASS SAFETY ACHIEVEMENTS

Cementation Mining:

  • 4 Star NOSA grading
  • Won competition for highest 4 star

grading mine in the Bushveld region

  • 365 injury free days (18 March 2002)

Concor/Group Five Civil Joint venture:

STRATEGY ‘95

Increasing regulatory pressure Historical role of SO2 in environmentalism Worldwide trends in smelter technology Make virtue of necessity

  • Improve technology
  • Better process
  • Lower costs
  • Solve problem
  • No “Bandages”
slide-24
SLIDE 24

STRATEGY NOW

Production expanding Regulatory pressure here External interest focus

  • Local environment
  • Regulators
  • International groups
  • Anglo American plc
slide-25
SLIDE 25

STRATEGY NOW

Decouple furnace / converting operations Creates

  • Operational flexibility
  • Siting flexibility
slide-26
SLIDE 26

PROJECT DESIGN CRITERIA - ENVIRONMENTAL

Reduce sulphur emissions

  • Current situation = 130 tpd SO2
  • DEAT requirements < 20 tpd SO

Implications

  • Acid plant downtime = Smelter downtime
  • Collection and treatment of converter and

furnace off-gas

  • New acid plant technology
  • Improved containment
  • Process robustness
slide-27
SLIDE 27

World Leader in Platinum Annual Facility Visit

PROJECT DESIGN CRITERIA - ENVIRONMENTAL

Hourly SO2 ground level concentrations (GLC) exceedences < 2 per year Implications

  • Collection of substantially all secondary
  • ff-gas sources and emit via stack(s)
  • Improved containment at source
