Closure or Salvage? Rethinking the Future of South Africa’s Old Mines
Loading player...
Andrew van Zyl on rehabilitation, mine closure, and hidden value.
Mine closure is usually treated as the final chapter in a mining asset’s life. But what if closure is the wrong question?
In this episode of #BelowTheSurface, Kevin Lester and Lily Nupen are joined by Andrew van Zyl, Managing Director of SRK South Africa, together with logistics strategist Evert de Ruiter, to explore one of the mining industry’s most overlooked challenges: what happens after mining ends.
South Africa has thousands of legacy mining sites, billions of rand in environmental liabilities and only a handful of formal closure certificates. At the same time, changing technology, evolving commodity markets and new geological understanding are creating opportunities in places once considered exhausted.
The conversation begins with a simple but uncomfortable observation. More than twenty years after the MPRDA came into force, South Africa has issued remarkably few closure certificates, despite substantial rehabilitation obligations and financial provisions held across the industry. That reality raises a deeper question: are we thinking about closure in the right way?
The discussion explores:
• Why mine closure remains so difficult in practice
• The role of rehabilitation funds and financial provision
• Whether rehabilitation can become a specialised business model
• The concept of “salvage” as an alternative to permanent closure
• Why old mines sometimes become valuable again decades later
• The lessons of Steenkampskraal, O’Kiep and other revived mining assets
• The importance of transparency, data and a modern cadastral system
• How policy can encourage innovation while protecting environmental outcomes
• The relationship between rehabilitation, exploration and future economic opportunity
• Why regulatory frameworks need continual iteration rather than periodic overhaul
Along the way, the conversation touches on engineering capability, institutional trust, commodity cycles, hidden mineral value and the unintended consequences that can arise when policy focuses too narrowly on today’s economic reality.
For mining executives, regulators, investors, lawyers, consultants and environmental specialists, this episode offers a thoughtful examination of what responsible closure should mean in a resource-rich country where yesterday’s waste can become tomorrow’s opportunity.
The discussion ultimately lands on a provocative idea: perhaps the choice is not between mining and closure. Perhaps the real challenge is creating a pathway between them that preserves future possibilities while meeting present obligations.
