Elizabeth Bay diamond mine revival: project and capex lens for coastal engineers

30 Second Briefing
Dutch private equity firm Kenzoll Capital and Namibian partner MSF Commercials plan a $50 million restart of the Elizabeth Bay diamond mine in the Sperrgebiet, targeting 10.5 million carats of combined onshore and offshore resources and funding exploration for additional minerals. The move follows a 67% collapse in Namibia’s diamond export value from NAD 5.1 billion ($306.9 million) in 2022 to NAD 1.7 billion ($102.3 million) in 2025, which the Bank of Namibia flags as a major drag on growth. For engineers and contractors, the project signals renewed capital for coastal brownfield mine infrastructure and marine-linked resource development in a previously uneconomic De Beers asset.
Technical Brief
- Kenzoll Capital has already deployed over $10 million in-country ahead of the $50 million restart.
Our Take
The 67% fall in Namibia’s diamond export value from NAD 5.1 billion in 2022 to NAD 1.7 billion in 2025 suggests that bringing Elizabeth Bay and the wider Sperrgebiet operation’s 10.5 million carats back into production is likely being timed against a very soft price and demand environment, so operators may prioritise flexible, modular mining and processing over high fixed-cost infrastructure.
With De Beers’ diamond empire reportedly valued at US$18 billion but facing a potential sale at around US$1 billion, secondary buyers like Kenzoll Capital stepping into assets such as Elizabeth Bay in Namibia are effectively positioning for distressed-style diamond valuations, which could reset cost and margin expectations across older marine and coastal deposits in our Mining project coverage.
The Bank of Namibia’s visibility in a context where diamond exports have shrunk to about US$102.3 million by 2025 implies that even relatively modest restarts can move the macro needle, giving regulators and central bankers more incentive to fast-track permitting and foreign-exchange approvals for brownfield diamond projects than for greenfield critical minerals such as graphite in the current pipeline.
