Africa’s mining wealth remains among the most concentrated globally, with a small group of billionaires controlling vast mineral fortunes.

From diamonds and gold to platinum group metals and copper, these tycoons dominate a sector critical to global supply chains.

As of 2026, South Africa continues to lead Africa’s mining wealth landscape, supported by deep capital markets, established operators and decades of industry development.

Despite the continent’s vast mineral reserves, only a handful of individuals have scaled to billionaire status, reflecting the high capital intensity and global exposure required in mining.

Africa’s mining wealth remains highly concentrated with only two figures, Nicky Oppenheimer and Ivan Glasenberg, commanding fortunes above $10 billion, highlighting how scale and global market access shape mining wealth.

Beyond them lies a fragmented group of investors, operators and dealmakers navigating regulatory risks, energy constraints and rising ESG pressures.

Commodity price gains through 2025, particularly in gold and platinum group metals, boosted fortunes unevenly. The next phase of growth, driven by lithium, cobalt and copper, may determine whether Africa produces a broader base of mining billionaires.

In this report, Shore Africa profiles the 10 wealthiest figures in Africa’s mining landscape, examining their business empires, investment strategies, and the evolving role of mining in shaping the country’s economic future.

5. Christo Wiese
Net Worth: $1.9 billion
Christo Wiese, a South African 84-year-old billionaire and retail magnate, is reigniting his early ties to diamond mining through Trans Hex Group. Best known for his stake in Shoprite Holdings, Africa’s largest retailer, Wiese first entered the diamond industry in 1976 but exited to finance the acquisition of Pepkor, a pivotal move in his retail empire. Now, his mining unit is exploring the Kaapvaal Craton, a diamond-rich region which geologists believe has shaped South Africa’s mining legacy for over 2.5 billion years. Co-owned by his son-in-law, Trans Hex aims to diversify into phosphate, lithium, gold, and platinum using advanced technology. Despite his net worth plunging from $7 billion to $1.9 billion after the 2017 Steinhoff crisis, Wiese remains undeterred, citing employment creation and foreign currency generation as key benefits of his mining resurgence.
