Material Changes Versus Prior Period
Compared to December 31, 2010, the following material changes occurred:
- Mineral Reserves: Increased by 5% (post-depletion) to 80.6 million ounces from 76.7 million ounces.
- Mineral Resources: Decreased by 4% to 217.0 million ounces from 225.4 million ounces.
- West Africa Region: Resources increased 46% (to 25.2 Moz) and Reserves increased 21% (to 13.7 Moz), driven by higher gold prices and discoveries at the Greater Damang Project.
- South Africa Region: Resources declined 8% (to 160.2 Moz) due to geological model changes, while Reserves increased 2% (to 60.2 Moz) due to additions at South Deep and the West Wits Tailings Treatment Project (WWTTP).
- South America Region: Cerro Corona Reserves improved 15% (to 6.1 Moz) due to increased Tailings Storage Facility capacity.
- Ownership Changes: Attributable portions for Tarkwa and Damang increased from 71.1% to 90% following the IAMGold buyout. Attributable portion for Cerro Corona increased from 80.7% to 98.5%.

Investor Verification Checklist
- Verify the impact of the 30% increase in gold price assumptions (from $1,000 to $1,300/oz) on the reported reserve increases.
- Confirm the timeline and capital requirements for the four major growth projects mentioned (APP, Chucapaca, Woodjam, Yanfolila).
- Review the upcoming Technical Short-form reports (expected April 2012) for detailed geological data supporting the reserve upgrades.
- Assess the financial implications of the increased attributable ownership in Tarkwa, Damang, and Cerro Corona on future cash flows.
- Monitor the West Wits Tailings Treatment Project (WWTTP) for its contribution to reserves and potential operational challenges.
