• the number of work-related fatalities;
• the company’s value added statement;
• the number of malaria cases in Ghana; and
• in respect of environmental data:
• direct raw materials processed;
• energy usage;
• greenhouse gas emissions;
• environmental incidents; and
• land owned, leased or managed.

Unless otherwise stated:

• $ refers to US dollars
• Moz refers to millions of troy ounces
• t refers to metric tonnes

Data covers operations, joint ventures and subsidiary companies which are managed by AngloGold Ashanti only and does not cover operations managed by joint venture partners.

Data relating to the Tau Lekoa mine is covered only until the finalisation of the sale of that operation effective 1 August 2010.

Data pertaining to exploration projects has not been extensively reported, but only in instances where it is deemed to be material.

Rounding may result in computational discrepancies.
