Business Context and Reporting Period
This Form 6-K filing by Gold Fields Limited (GFI) covers the month of August 2008. The primary purpose of the report is to announce the company's updated Resources and Reserves Statement as of June 30, 2008. Gold Fields is a major unhedged gold producer with operations in South Africa, Ghana, Australia, and Peru. The company operates eight mines, with a ninth mine, Cerro Corona in Peru, commencing production in August 2008.
Key Financial and Operational Metrics
- Reserves: Total attributable precious metal reserves are 83 million ounces (moz), calculated using SEC-mandated historical average commodity prices.
- Resources: Total attributable precious metal resources are 251 moz.
- Production Capacity: Annual attributable production is approximately 3.64 million ounces. The new Cerro Corona mine adds an initial rate of approximately 375,000 gold equivalent ounces per annum.
- Valuation Assumptions: Reserves were calculated using gold prices of US$650/oz (Ghana/Peru), ZAR150,000/kg (South Africa), and A$750/oz (Australia). Copper was valued at US$1.75/lb.
- Alternative Valuation: Using spot gold prices of approximately US$810/oz, reserves would be approximately 91 moz.
Material Changes Versus Prior Period
Compared to December 31, 2006, the following changes occurred net of 5.7 moz depletion and asset sales (Choco 10 Gold Mine and Essakane Project):
- Resources: Remained flat at 251 moz (down from 252 moz), representing a 4% increase after accounting for depletion.
- Reserves: Decreased by 12% to 83 moz (down from 94 moz), representing a 4% decrease after accounting for depletion.
- Safety Adjustments: A pillar and remnant mining review resulted in the removal of 600,000 oz of reserves at Driefontein (3% of total mine life reserves) and 500,000 oz at Kloof (5% of total mine life reserves).
Guidance, Outlook, and Management Commentary
CEO Nick Holland emphasized that the 83 moz reserve base remains one of the strongest in the industry, supporting an aggressive growth strategy driven by the 251 moz resource base. Management highlighted significant upside potential in the ore bodies, noting that resource prices reflect a 20-23% premium over reserve prices, aligning more closely with recent spot prices.
Production Guidance (Post-Safety Review):
- Driefontein: Projected at 6,400kg in Q1F2009, stabilizing at 6,800kg in Q2F2009 and beyond.
- Kloof: Projected at 3,900kg in Q1 and Q2F2009, stabilizing at approximately 6,000kg in Q3F2009 and beyond.
The filing states that these projections are consistent with guidance provided on August 1, 2008. The full 2008 Resources and Reserves Supplement is scheduled for publication with the F2008 Annual Report on September 29, 2008.
Investor Verification Checklist
- Verify the impact of the 1.1 million ounce reserve reduction due to safety reviews at Driefontein and Kloof on long-term production profiles.
- Confirm the actual production ramp-up rates for the new Cerro Corona mine in Peru against the initial 375,000 oz guidance.
- Monitor the divergence between SEC-mandated reserve valuations (US$650/oz) and current spot prices (approx. US$810/oz) to assess potential reserve reclassification upside.
- Review the upcoming F2008 Annual Report (September 29, 2008) for detailed financial performance data, as this 6-K focuses on resource metrics rather than financial statements.
