JOHANNESBURG – Back in 1987, South African President Cyril Ramaphosa – then a 34-year-old labor union leader – led 300 000 black miners in a strike that symbolized resistance to the apartheid regime. Now, striking gold workers face a less politically charged battle, but one they can’t win.

The nation’s 130-year-old gold industry – which has produced half the bullion ever mined on earth – is locked in the final stages of a decades-long death spiral. Most of South Africa’s gold mines are unprofitable at current prices.

Dwindling output has cut gold’s contribution to little more than 1% of the South African economy, down from 3.8% in 1993 – the year before Nelson Mandela’s African National Congress won the country’s first democratic elections. While the industry’s demise won’t reverberate in the way it once would have, the mines minister has criticized Gold Fields’s plan to cut jobs as the ruling ANC seeks to shore up its base before elections next year.

Operations at mines run by Gold Fields and Sibanye Gold in South Africa have been halted by strikes over job cuts and wages respectively. Both producers cut their output projections for this year.

South Africa’s gold industry now employs just over 100 000 people, less than a fifth of the number that used to power the apartheid economy. The economic and social impact of a further contraction in the industry will be magnified as every gold miner supports between five and ten dependents, while creating two jobs elsewhere, according to the country’s Minerals Council.

Higher wages and power prices, combined with the geological challenges of the world’s deepest mines, will mean more job losses and less production in the country over the next five years, said Gold Fields CEO Nick Holland.

“When you work out the math, when you keep doing that year after year, you are going to go out of business very quickly,” Holland said in an interview. “The industry will just continue to see a slow death.”

Workers at Gold Fields’ South Deep mine have been striking since November 2, protesting the producer’s plans to cut jobs as part of a restructuring to stem losses.

A strike over wages at three mines owned by Sibanye, the country’s biggest producer, is entering a third week. CEO Neal Froneman acknowledges that pressure is building on the miner to resolve its safety problems after more than 20 fatalities this year. If that can be done, he’s optimistic that South Africa’s gold mines can survive a little longer.

“It’s an industry in decline, yes, and if sunset means the sun setting in 10 years or 15 years, that’s still 10 or 15 years away,” Froneman said in an interview last month. “There is still money to be made.’’
