Bogota – At the cost of 25 years of their lifespan, workers toil 60 hours a week for $9 a day in the bowels of a mine that once funded an empire.
When the Spanish came to Cerro Rico (Rich Mountain) in the 16th Century, they hoped to find gold. But the cone-shaped mountain looming over the city of Potosi and now riddled with makeshift tunnels and unstable shaft systems produced silver.
“You could build a silver bridge from the mountain to Madrid from what was mined here,” said Freddy Suarez, a guide who takes visitors to see Cerro Rico.
“For 20 years I worked in the mine after starting at 10. My father was a miner here too. There is still as much silver in there as has been taken out, but it is getting harder to get to and more dangerous. Tunnel collapses are common and the dangers our ancestors faced are still present.”
A century after the Spanish arrived, Potosi was one of the biggest cities in Latin America and the wealthiest in the world. The busy extraction of silver and other minerals also made it the largest site of physical exploitation in the world, right through the 17th Century.
The phrase “Vale un Potosi” – It is worth a Potosi – became a commonly used expression to describe vast wealth after Don Quixote blurted it out in Miguel de Cervantes’ great work of that name.
But the apparent wealth of Potosi, the highest city in the world at 4,050 meters (13,290 feet), overlooked the human sacrifice that made it possible. Countless natives were taken into forced servitude to toil in the mines alongside African and Indian slaves, working in squalid and extremely dangerous conditions.
While records of fatalities were not kept, historians and geologists estimate that about 8,000,000 miners perished in this way in South America during the Spanish colonial period, from 1546 to 1825.
“Miners believe that their ghosts are still in the mines,” Mr. Suarez said, adding that Cerro Rico’s nickname – The Mountain That Eats Men” – is still used today.
After coming out of Potosi’s cobbled, narrow streets, the road up to the mine is dotted with stalls selling cigarettes, dynamite, ammonia and soft drinks to tourists, all meant to be given as presents to the miners.
Small treats, perhaps, given the lives these men lead.
Working conditions in the mine are primitive: the air is unbearably hot and stuffy due to a lack of ventilation and is thick with flammable dust generated from the blasting of rock. The tunnels are poorly lit and narrow, restricting the workers’ movement. The only signs of modernity are the pneumatic drills that have replaced pickaxes.
Lung disease, mercury poisoning and exhaustion cause sickness and death among the miners, whose life expectancy is less than 40 years. And accidents, especially with dynamite and falls from unstable ladders, are still common.
“Hear that?” said Mr. Suarez, as a tapping sound rang out on the ventilation pipes. “It means there are going to be explosions; the number of taps indicates the number of blasts. Four taps, four blasts.”
Mr. Suarez took the tour group down two levels for shelter from the explosions. “We will wait here until we get the all clear,” he said, before a series of blasts shook the mine and dust rained down through the tunnels.
“Before the dust settles, the rocks are carried up in bags to different levels, and then loaded on to containers, and then pushed out in ore carts – where other miners sift through for silver deposits.”
In the lower levels, where adults cannot squeeze through, children wriggle in to extract rocks that may have silver or the less precious zinc.
Working for 10 hours a day, the miners chew coca leaves to suppress hunger and fear. A firm, golf ball-sized wodge is formed in the mouth and typically lasts for a whole shift. No food is eaten in the mine as miners believe this would make them less alert. Women are prohibited except in tour groups.
“There are 250 miners who work officially in here, but 8,200 people work around the mine in analyzing the output,” Mr. Suarez said.
“Miners get 65 Bolivianos a day ($9.27) and work six days a week. However, there is nothing to stop miners from freelancing, and they get paid according to what they can carry out themselves in their own hands.
“This is often very little, say a couple of bolivianos a day, but they all dream of finding a lump of silver.”
Juan, Enriqué and Miguel spend their shifts on Level 5, deep in the bowels of the mountain. They drill the holes, then stuff them with dynamite.
“I have been working here for five years,” said Juan, 18. “We try to keep track of the silver seam but with the dust it can be hard to see.
“Also there are other minerals down here, like zinc, not as valuable as silver. We try to avoid a zinc seam. There is no money in it.”
Working deep inside Cerro Rico has given rise to a dark sense of humor among those who spend their days there.
“We are underground like those in the cemetery,” said Enriqué, 19, caked in dust and struggling for breath, with red eyes and a mouth full of coca leaves. “Except they are better looked after.”
