Certain statements contained in this document, other than statements of historical fact, including, without limitation, those concerning
the economic outlook for the gold mining industry, expectations regarding gold prices, production, cash costs and other operating
results, return on equity, productivity improvements, growth prospects and outlook of AngloGold Ashantis operations, individually or in the aggregate, including the achievement of project milestones, commencement and completion of commercial operations of certain
of AngloGold Ashantis exploration and production projects and the completion of acquisitions and dispositions, AngloGold Ashantis liquidity and capital resources and capital expenditures and the outcome and consequence of any potential or pending litigation or
regulatory proceedings or environmental issues, are forward-looking statements regarding AngloGold Ashantis operations, economic performance and financial condition. These forward-looking statements or forecasts involve known and unknown risks, uncertainties
and other factors that may cause AngloGold Ashantis actual results, performance or achievements to differ materially from the anticipated results, performance or achievements expressed or implied in these forward-looking statements. Although AngloGold
Ashanti believes that the expectations reflected in such forward-looking statements and forecasts are reasonable, no assurance can
be given that such expectations will prove to have been correct. Accordingly, results could differ materially from those set out in the
forward-looking statements as a result of, among other factors, changes in economic, social and political and market conditions, the
success of business and operating initiatives, changes in the regulatory environment and other government actions, including
environmental approvals, fluctuations in gold prices and exchange rates, the outcome of pending or future litigation proceedings, and
business and operational risk management. For a discussion of such risk factors, refer to the document entitled Risk factors related to AngloGold Ashantis suite of 2012 reports on the AngloGold Ashanti online corporate report website at www.aga-reports.com. These factors are not necessarily all of the important factors that could cause AngloGold Ashantis actual results to differ materially from those expressed in any forward-looking statements. Other unknown or unpredictable factors could also have material adverse
effects on future results. Consequently, readers are cautioned not to place undue reliance on forward-looking statements. AngloGold
Ashanti undertakes no obligation to update publicly or release any revisions to these forward-looking statements to reflect events or
circumstances after the date hereof or to reflect the occurrence of unanticipated events, except to the extent required by applicable
law. All subsequent written or oral forward-looking statements attributable to AngloGold Ashanti or any person acting on its behalf are
qualified by the cautionary statements herein. This communication may contain certain Non-GAAP financial measures. AngloGold Ashanti utilises certain Non-GAAP performance measures and ratios in managing its business. Non-GAAP financial measures should
be viewed in addition to, and not as an alternative for, the reported operating results or cash flow from operations or any other
measures of performance prepared in accordance with IFRS. In addition, the presentation of these measures may not be comparable
to similarly titled measures other companies may use. AngloGold Ashanti posts information that is important to investors on the main

This is a potential game changer for South African mining
and is progressing towards commercial application.
Developing prototype of key technologies to
potentially automate parts of AngloGold Ashantis deep-level underground mining operations
This technology has the potential to improve
productivity by reducing mining of waste and
extracting mainly gold-bearing reef
Could lead to opportunities to produce gold from
high-grade shaft pillars where development is
largely done
Four additional 30m holes completed during Q1,
2013
Design of first production machine underway
Two long holes successfully filled with Ultra High
Strength Backfill show viability of technology
Focus is now on linking the technologies into a
commercially viable, integrated production system

Technology initiative Sunrise Dam underground RC drilling
Intensive development of GQ started in 2012.
Success of RC drilling for grade control in the open pit
applied to underground
Underground RC trials in October 2012 gave excellent
preliminary results
3-4 times faster than diamond drilling
Increased sample volume and density
High quality assay data for robust grade control modelling
Moved to full RC Grade Control in November 2012
...converting resource into reserve quickly.

New grade control approach suits bulk mining .
...leading to potential significant savings in underground development costs.
Infill with production holes after sampling
Conditional simulation with stope optimisation enables a lower cost, bulk mining approach
115mm RC holes have the ability to drill 60m, removing the need for intermediate levels
