Slide 5: Overview of Barberton Mines ('BML')
OVERVIEW OF BARBERTON MINES (‘BML’) • Mining started in 1886 at Sheba Mines – oldest operating mine • Currently BML have three operations i.e. Sheba, New Consort and Fairview • BML treat about 24 000 ore tons per month at about 11g/t • BML also have a Tailings Retreatment Plant (90,000t/m) • Combine

Slide 20: Current Mining Methods
CURRENT MINING METHODS
Slide 21: Current Mining Methods
CURRENT MINING METHODS • Mechanised Mining – Cut and fill (90%) Breast & Updip • Open Stoping – Conventional Mining (10%) • Shrinkage Mining (0%) 21
Slide 22: Current Mining Method
CURRENT MINING METHOD • Mechanised Mining – Cut and fill (90%) Waste from your infrastructure development is hauled back into stope for fill (Ramp system and Access cross cut which is then fan lifted) 55% of reef tons removed equates to waste tonnage requirement for waste fill (Development meter

Slide 33: Fall of Ground Measures
FALL OF GROUND MEASURES • Mechanised Mining – Cut and fill (90%) Because the back areas are filled with waste the overall stability of the stopes are good At Fairview we are mining at about 1800m below surface and have not seen any seismic related activities Only the current stope face area is
Slide 34: MRC Ore Body and Exploration Potential
MRC ORE BODY AND EXPLORATION POTENTIAL
Slide 35: Barberton Mines - Fairview
BARBERTON MINES - FAIRVIEW • The MRC is the second richest orebody in the world • Current life of orebody is 26 years, which greatly exceeds the BML life of mine • There is a realistic potential for MRC to continue at depth 35

Slide 41: Metamorphic Devolatilisation
BARBERTON MINES Metamorphic devolatilisation Transition from greenschist to amphibolite facies triggers process of devolatilisation H2O-CO2-H2S fluids are released from mineral crystal structures and these fluids can transport gold to favourable depositional sites Adequate amounts of gold can
Slide 42: Metamorphic Devolatilisation
BARBERTON MINES Metamorphic devolatilisation At higher pressure (and T) gold solubility is higher When pressure is released, H2S (the ligand that makes gold soluble) is driven off, resulting in gold precipitation Pressure shadows, which can form during faulting and folding, create spaces effec
