Mine Design

• Ore body situated between 2,000m and 3,800m below
  surface
• The geological structure is complex and
  highly-faulted with large fault loss areas
• It was decided to site the new shaft in Great
  Noligwas lease area. This provided the
  opportunity of extracting the shaft pillar before
  the shaft was excavated and equipped but required
  the development of long access tunnels to reef
• The main surface shaft and subvertical RV shaft
  has been sunk and will be equipped down to a
  depth of 2,300m and 3,164m respectively

Growth Moab Phase 2
In South Africa, the dramatically higher rand
gold price has contributed to a further 11
million additional ounces of gold to reserves,
resulting in the possible development of six
deep-level mining projects, currently being
studied. AngloGold quarterly results31 October,

Growth Moab Phase 2
Moab Phase 2 below 101 level means an
additional 4.6Moz of gold production should this
project go ahead. Moab Khotsong has the
potential to produce some 9Moz from the Phase 1
and 2 projects.Capex for Moab Phase 2 is
estimated at approximately R1.8bn. It will also
extend the LOM from 2015 2022. A full
feasibility study into this project is expected
to commence in 2003.
