Gold mining was once the foundation of South Africa’s economic growth, powering national development for much of the 20th century. Over the last several decades, however, the industry has experienced a significant collapse, resulting in the loss of over 440,000 jobs since the late 1980s. This long-term decline is reflected in historical data sourced from the Department of Mineral Resources and Energy, which highlighted the scale and progression of these job losses. The figures expose not just a shrinking sector, but a slow erosion of livelihoods in mining communities across the country.
Key Takeaways
- Massive Job Losses Over Decades: South Africa’s gold mining sector has lost over 440,000 jobs since the late 1980s, with employment falling from more than 536,000 in 1988 to just 94,000 in 2023.
- High Operating Costs Threaten Viability: Deep-level mining in South Africa is becoming increasingly expensive due to rising electricity and water costs, with energy now consuming up to 20 percent of operational budgets.
- Reserves Remain, but Extraction Is Uneconomical: Despite an estimated 68 million troy ounces of gold remaining underground, much of it is too costly to extract under current economic and infrastructure conditions.

A Historic Industry That Shaped a Nation
South Africa’s gold mining history began in 1886 following the discovery of gold on the Witwatersrand. This event ignited a frenzied gold rush, laying the groundwork for the birth of Johannesburg and the growth of a mining sector that would become globally dominant. The Witwatersrand’s exceptionally rich gold deposits positioned South Africa as the world’s foremost gold producer. British financial backing and a labour force composed largely of underpaid black migrant workers, underpinned by apartheid-era policies, enabled the industry to expand rapidly throughout the 20th century. Entire townships and industrial hubs grew around this industry, and for many, gold mining symbolised prosperity, power, and national pride.
Technological advances in deep-level mining techniques and surging international demand further accelerated growth. By the 1970s, South Africa was responsible for more than two-thirds of the world’s gold production, with annual output exceeding 1,000 tonnes. During this period, gold became a pillar of the national economy, helping to fund large-scale infrastructure development and industrial expansion. Rail networks, power stations, and schools were all indirectly financed by the revenues generated from the gold sector.
The Decline Begins: Economic and Operational Challenges
However, the upward trajectory came to a halt by the 1980s. Diminishing ore grades and escalating operational costs began to erode profitability and production levels. Gold mining’s share of the country’s GDP dropped sharply from roughly 20 percent in the early 1980s to just 6.3 percent by 2023. This economic downturn also hit employment hard. In 1988, the industry supported just over 536,000 jobs. That number had plummeted to 217,000 by the year 2000 and further down to 94,000 by 2023. The sector has therefore shed 442,000 jobs over a span of 35 years, averaging more than 12,000 job losses annually or approximately 35 per day. This relentless decline has hollowed out mining towns, left families without income, and deepened poverty in regions that once thrived on mining wages.
Untapped Potential Still Underground
Despite widespread mine closures, the country’s gold reserves have not been exhausted. A 2023 report by PwC indicated that South Africa still holds an estimated 68 million troy ounces in gold reserves. This quantity could theoretically sustain production for another 27 years. However, reaching these remaining deposits is financially burdensome. The depth of the reserves requires miners to excavate several kilometres below the surface, which significantly raises the cost of extraction. This challenge is further worsened by South Africa’s soaring electricity and water tariffs. It is not a lack of resources that threatens the industry’s survival, but the unsustainable economics of accessing them.
High Costs Undermining the Sector
The Minerals Council South Africa (MCSA) has emphasised that the country’s gold sector is heavily reliant on deep-level, labour-intensive underground mining. To access the remaining gold, companies must dig deeper than ever before, often into shafts where extreme temperatures and high humidity are common. These working conditions not only make it difficult to maintain safe environments but also reduce workforce efficiency and push up costs significantly.
Miners are forced to endure heat levels that would be intolerable in most industries, with ventilation systems working overtime just to keep operations marginally bearable.
Electricity is particularly crucial in such deep-level operations, being used for functions such as pumping water, maintaining air circulation, and cooling. The MCSA has repeatedly pointed out that the escalating price of electricity has placed immense pressure on mining operations. Eskom’s history of seeking large tariff increases, whether approved in full or partially, has only compounded the financial strain. Electricity bills in some mines now outstrip labour costs, creating a grim financial imbalance.
Wider Impact of Rising Energy Costs
The MCSA has outlined three main consequences of increased energy costs. Firstly, they reduce overall profitability, prompting mining companies to invest more in energy-saving measures and to shift towards renewable energy sources such as solar and wind. Secondly, the rising costs lead to shorter operational lifespans for mines. As electricity costs make it financially impractical to process low-grade ore, companies are forced to focus solely on high-grade areas, hastening mine closures even though viable reserves still exist. This strategic retreat from marginal areas sacrifices jobs, reduces community investment, and speeds up the collapse of associated industries.
Lastly, electricity represents a fixed overhead in mining operations, especially in deep-level mines that require constant ventilation, cooling, and water pumping, regardless of whether any ore is being extracted. The MCSA has estimated that electricity now consumes up to 20 percent of total operational expenditure. Combined with high water costs and declining ore quality, these financial burdens have pushed many companies to close down their mines rather than continue running at a loss. The equation has become brutally simple for many mine operators: continue bleeding money or cut their losses and walk away.
Collapse in Output and Uncertain Future
Gold production in South Africa has declined drastically from 620 tonnes in 1988 to only 97 tonnes in 2023. While gold continues to lie deep beneath the surface, the economics of modern mining have rendered much of it financially inaccessible. The future of South Africa’s once world-leading gold mining industry remains uncertain, weighed down by structural challenges that show little sign of easing. Unless there is a radical shift in energy policy, mining technology, or global gold prices, the industry risks becoming little more than a chapter in South Africa’s economic history.
Conclusion
Once the backbone of South Africa’s economy, the gold mining industry now faces a crisis rooted in deep operational challenges, mounting costs, and a shrinking workforce. While vast gold reserves remain untapped beneath the earth’s surface, the harsh financial realities of extraction—driven by rising electricity prices, water expenses, and declining ore grades—have turned a historically thriving sector into one of survival rather than growth. Without significant reform or innovation, the future of gold mining in South Africa looks increasingly uncertain.
