MINING.COM’s ranking of world’s 50 most valuable miners enjoyed a combined market capitalization of $1.51 trillion at the end of Q3, up by single digits since the start of the year compared to rip-roaring broader US and world markets.
Much of the drag on the index comes from the top – the mining industry’s traditional Big 5 – BHP, Rio Tinto, Glencore, Vale and Anglo American. With the exception of Anglo, which received a fillip from BHP’s approach, the stocks are deep in the red for 2024.

The humble bird, which was employed until 1986, represents an important part of mining history
Never mind the gas—it was automation that got them in the end. Throughout much of the 20th century, chirping canaries were staples of the coal mining industry. As coal miners descended into the earth—entering a harsh environment often home to poisonous gases like carbon monoxide—they would bring the yellow birds along as safety mechanisms.
Because carbon monoxide is clear and odorless, miners needed a method for detecting a leak before it killed them. In the mine, a canary’s collapse let workers know there was poisonous gas in the air and gave them some warning time to evacuate.
One of the greatest imperialists of the British Empire, Cecil John Rhodes’ legacy is today considered highly problematic.
Cecil John Rhodes is a historical figure who has generated huge amounts of debate, not just in South Africa, where he lived much of his life, but across much of the Anglosphere, where his name continues to bear considerable weight and influence.
He was indeed a powerful man who advanced and industrialized parts of the world, bringing colonial progress, wealth, and success to lands under his influence. However, his legacy in the English-speaking world has come under intense scrutiny as those whose ancestors benefitted from his imperialism are made aware of the dark side of his methods.
What the chain of diamonds trickling from the marketplaces of Golconda tells us about the dynasties that branded and traded, and won and lost them
When it comes to diamonds, they say, nothing surpasses Golconda. Before the current problematic era of Blood diamonds, Golconda’s rocks shone the brightest. The only known source of the stone till the early 18th century, the mines of Golconda produced diamonds unparalleled in their ability to spawn legends and bewitch the beholder.
These mines put the gem on the world map and marked India as the original home of the adamas, the Greek root word for this indestructible jewel. For this reason, Golconda’s ancient mines, pre-dating dynasties of the last two millennia, were a source of wealth and influence for the powers that controlled them through the ages.
Commentary: Here’s how the experts buy gold rings and bracelets for less than the scrap price
There was lots of humming and huffing in our household this week after gold prices hit a record high recently. Not that I can afford even the smallest memorial coin. But my wife is a jeweller, so we have skin in the game. I rarely comment on gold. When journalists do, insane end-of-worlders leap from their bunkers to scream abuse. Fiat money is a sham. Governments can’t be trusted. Zombies are coming.
And the yellow metal isn’t the most expensive ever. After adjusting for inflation, its peak was July 2020, with real prices on a downward path since. But loads of readers suddenly want to know more about gold — so here goes.
Sitting at an altitude of 2,700 metres, Real del Monte is a pretty town in the Mexican state of Hidalgo. But with its architecture, heritage of silver mining and meat pasties, it is also a little slice of Cornwall, a region in the southwest of England.
The silver mines surrounding Real del Monte were the source of more than half the silver produced during the 300 years that Spain rule Mexico (1521–1821). By 1824, however, they were in bad condition, and were bought by a group of English investors.
A decade after the Spanish Conquistadores toppled the Inca Empire (1532-34), an indigenous Andean prospector, Diego Gualpa, in 1545, stumbled onto the richest silver deposit in the world on a high mountain of 4,800 meters (15,750 feet) in the eastern cordillera of the Bolivian Andes.
Here in the shadow of what the Spaniards called the “Cerro Rico” (“Rich Mountain”) at 4,000 meters (13,200 feet) a mining boom town quickly developed. By the end of the sixteenth century, it had become one of the largest and the highest cities in the world, and in 1561, Philip ll of Spain, decreed that it should be known as the “Villa Imperial de Potosí.”
When 19-year-old Ann Bowcot from Dowlais was interviewed for the 1842 Children’s Employment report, she told the investigators that when she started work at the mines she was so small she had to be carried on her father’s shoulders to work.
She was not alone. It was common to see men carrying small children in the dark hours before dawn to the mine, where they would descend and remain most of the day. Society was appalled, and demanded something be done. The 1833 Factory Act had restricted the employment of children but why, people were asking, had this Act not been applied to other industries such as mining – so the government ordered an investigation.
Brief Overview of the Brazilian Gold Rush
In 1693, a significant event unfolded in Brazil, then a Portuguese colony – the Brazilian Gold Rush. This period was more than just a discovery of gold; it was a transformative era that shaped the nation’s destiny.
Ten Facts about the Brazilian Gold Rush
The Discoverer of Gold: It’s believed that the Brazilian Gold Rush began in 1693 when a group of bandeirantes, Portuguese colonial scouts, found gold in a tributary of the Rio Doce. Bartolomeu Bueno de Siqueira is often credited as the initial discoverer.
The scars left behind by the collieries of Wales’ Rhondda Valley are beginning to heal, but some things never change.
Scarcely an hour’s drive west of the pristine villages, prosperous cottage gardens, and sylvan landscapes of the Cotswolds lies the southern Welsh county of mid-Glamorgan. Throngs of touring coaches, camera-wielding photojournalists, and well-heeled tourists don’t come here. These are the valleys of the Rhondda.
In the Valleys
Fanning out above the Welsh capital of Cardiff, these valleys are the coalfields of South Wales, narrow glens snaking their way south to north, from the Bristol Channel coast toward the Brecon Beacons. Every few miles up and down the hills lie the skeletal remains of a pit head, rusting silently, majestic.

I shed tears within 30 pages. I expect you would too and, if you’re a miner, so you should. In a recently-published novel we are taken back to a small mining town in October 1966 when our industry killed children, young children, half a school of them.
Published by Faber & Faber, ‘A Terrible Kindness’ reminds us (as Jo Browning Wroe writes in her opening sentence) of when “something dreadful happened in Wales.” In Aberfan on that dark morning, 116 children (mostly between the ages of seven and 10) went to school and didn’t come back.

If you ask the average person in the street when they think the history of mining begins in the Americas, they might pinpoint the throng of the forty-niners who migrated to California in search of gold (bequeathing a name to San Francisco’s NFL team). Or perhaps they would recall the mad dash northward to the Klondike in 1898, made famous in the fiction of Jack London, the poetry of Robert Service, the popular history of Pierre Berton, and even a classic film by Charlie Chaplin.
Some might go as far back as the large-scale precious metal mines that brought the Spanish to Central America in the 16th century. But almost nobody would acknowledge that mining in the Americas originated thousands of years ago as a critical cultural and economic activity of Indigenous People.
An international team of researchers ran chemical and isotopic analyses of copper artifacts from southern Africa and discovered new cultural connections among people living in the region between the 5th and 20th centuries.
In a paper published in the journal Plos One, the researchers explain that people in the area between northern South Africa and the Copperbelt region in central Africa were more connected to one another than scholars previously thought.
The majestic structures of ancient Rome have survived for millennia — a testament to the ingenuity of Roman engineers, who perfected the use of concrete. But how did their construction materials help keep colossal buildings like the Pantheon (which has the world’s largest unreinforced dome) and the Colosseum standing for more than 2,000 years?
Roman concrete, in many cases, has proven to be longer-lasting than its modern equivalent, which can deteriorate within decades. Now, scientists behind a new study say they have uncovered the mystery ingredient that allowed the Romans to make their construction material so durable and build elaborate structures in challenging places such as docks, sewers and earthquake zones.

The U.K. no longer springs to mind as a mining giant, but we used to have a dominant role in the global industry. The extraction of non-ferrous metals on these islands, particularly copper and tin, dates back to before 2000 BC, and surface workings for coal and iron ore were widespread after the beginning of the Iron Age around 750 BC. This mineral wealth was one of the things that attracted the attention of Rome.
The nation’s mining history comes to mind with the recent news (courtesy of the ‘North Wales Live’ website) that after 37 years of clearance work, volunteers are nearing their goal of breaking through to an unexplored section of Llandudno’s Ty Gwyn copper mine.
