Business Context and Reporting Period
Company: Gold Fields Limited
Filing Type: Form 6-K (Report of Foreign Private Issuer)
Date: October 24, 2016
Subject: Announcement of the Damang Gold Mine Reinvestment Plan in Ghana.
Gold Fields has approved a strategic reinvestment plan for its Damang mine to extend the Life of Mine (LOM) by eight years, from 2017 to 2024. This decision follows a strategic review initiated in 2015 due to declining production from lower-grade satellite deposits. The plan leverages a Development Agreement signed with the Government of Ghana in March 2016.
Key Financial Metrics and Project Economics
The Reinvestment Plan involves a total investment of US$1.4 billion in operating and capital expenditure over the LOM. Key operational and financial metrics for the 2017–2024 period include:
- Total Gold Production: 1.56 million ounces (Moz).
- Total Material Mined: 165 million tonnes (Mt).
- Total Material Processed: 32 Mt at an average grade of 1.65g/t.
- Average Mining Cost: US$3.60 per tonne.
- Average Processing Cost: US$16.25 per tonne.
- Average All-In Costs (AIC): US$950 per ounce.
- Reserves Increase: Proven and Probable Reserves increase by 72% to 1.68 Moz (31.5Mt @ 1.65g/t) compared to December 2015.
Material Changes and Strategic Shifts
The filing details a significant operational pivot from mining lower-grade satellite deposits to returning to the high-grade core of the main Damang orebody via a major cutback of the Damang Pit Cutback (DPCB). Key changes include:
- Operational Scope: A 341m deep cutback (265m pre-strip + 76m deepening) to access the Tarkwa Phyllite lithology.
- Production Profile: Production is forecast to ramp up significantly, peaking at 265,000 ounces in 2021 and 2023, compared to lower levels in the initial years (110,000 ounces in 2017).
- Cost Trajectory: AIC is projected to decline from US$2,265/oz in 2017 to US$605/oz in 2023 as higher-grade ore is accessed.
- Infrastructure: Construction of a new Far East Tailings Storage Facility (FETSF) is required as the existing facility approaches capacity.
Guidance, Outlook, and Risks
Management Commentary and Outlook: The plan is designed to enhance the Group's presence in Ghana and secure long-term production. Management retains optionality to expand operations further if the gold price sustains above US$1,400/oz. The project is expected to create and preserve 1,850 direct jobs, with significant local community engagement.
Capital Expenditure Profile: Major capital requirements include waste stripping, pre-development costs, and the construction of the FETSF. Stage 1 of the FETSF is planned for completion by end-2017. Minor capital work is required for the processing plant, primarily for SAG Mill shell replacement in 2018.
Risks and Contingencies: The filing notes that the decline in production since 2013 was exacerbated by grade variations. The success of the plan relies on the execution of the cutback and the mobilization of two mining contractors, expected early in 2017. The filing does not provide specific group-wide revenue, profit, or cash flow figures for the reporting period, focusing solely on the Damang project economics.
Investor Verification Checklist
- Verify the mobilization timeline of the two mining contractors scheduled for early 2017.
- Monitor the construction progress and capacity of the Far East Tailings Storage Facility (FETSF).
- Track the actual head grade achieved during the initial pre-strip phase (2017–2018) against the forecast of 0.90g/t and 1.25g/t.
- Assess the impact of the US$1.4 billion investment on the company's overall liquidity and debt profile, as group-wide financial statements are not included in this filing.
- Confirm the status of the Development Agreement with the Government of Ghana and any potential fiscal changes.
