The 27 tonnes of copper slabs are securely lashed down on the back of Omar Rachidi’s tractor-trailer. Now all he has to do is drive the cargo to its destination. But that’s easier said than done.

Two thousand kilometres (1,200 miles) of road lie between southeast DR Congo’s mineral belt and the Tanzanian port of Dar es Salaam, from where the copper will be shipped to Asia.

Kinshasa is already Africa’s biggest city – could cobalt make it the richest? – by Jason Mitchell (Mining Technology – February 15, 2022)


Kinshasa has had a turbulent past but has started to prosper as the Democratic Republic of Congo’s economy expands at more than 6% a year.

Kinshasa – the capital of the Democratic Republic of Congo (DRC) and Africa’s greatest megacity – is poised to benefit from the massive copper and cobalt boom under way in the country.

In terms of population, it is the continent’s largest city with 17.1 million people living in the greater area, only slightly smaller than the Netherlands (17.7 million). It is projected to become the world’s biggest city with a whopping 35 million inhabitants by 2050, 58 million by 2075 and 83 million by the start of the next century.

Chile’s Green Dream to Reinvent Itself Is Spooking Investors – by Valentina Fuentes and Ethan Bronner (Bloomberg News – February 10, 2022)

The country’s efforts to create a new constitution could serve as a model or warning for tackling climate change and inequality.

Constanza San Juan is feeling optimistic. She sits on a committee of Chile’s constitutional convention that on Feb. 1 voted to nationalize the country’s mineral wealth—its deep veins of copper, lithium, magnesium, and silver—a notion that has mining companies and markets hyperventilating.

The idea is sufficiently radical that few believe it will be endorsed by the required two-thirds of the full convention. But San Juan, a 36-year-old historian, not only hopes it will—she wants it to go further.

Copper’s vital role in low-carbon economy – by Nolan Peterson (North of 60 Mining News – February 11, 2022)

When most people think about the metals driving the alternative energy revolution, lithium, vanadium, cobalt and rare earths spring to mind. As recently reported by EE Times Europe, “Copper is an important raw material for the electronics industry, being the most widely used conductor for PCB, wiring, and connector manufacturing.

The average person, however, might not realize this, thinking that copper is some kind of old metal on which there is no progress to be made.” There is no more omnipresent and vital metal to the low-carbon economy than copper.

Panguna mine at centre of bloody Bougainville conflict set to reopen after 30 years – by Leanne Jorari (The Guardian – February 11, 2022)

The mine at the centre of the decade-long civil war between rebels in Bougainville and Papua New Guinea security forces is set to reopen 30 years after it was forced to close, following an agreement between local landowners.

Panguna was once one of the world’s largest and most profitable copper and goldmines and still contains an estimated 5.3m tons of copper and 19.3m ounces of gold, which would make the reserves worth about $60bn at today’s prices.

Two decades and $30 million later, a B.C. mine proposal is officially dead – by Matt Simmons (The Narwhal – February 9, 2022)

The Narwhal

They say that history repeats itself because nobody was listening the first time. B.C. rejected a proposed open-pit copper, gold and molybdenum mine for the second time Monday, spelling the likely end of a saga that lasted nearly 20 years, cost tens of millions of dollars and exposed flaws in B.C.’s environmental assessment process along the way.

Plans for the Morrison mine, proposed for the shores of Morrison Lake, known as T’akh Tl’ah Bin, about 65 kilometres from Smithers on Lake Babine Nation territory, go back to the ‘90s — although miners have been eyeing the area for its gold and copper since as far back as the ‘60s.

MMG (HKG: 1208) said on Monday that it will have to halt production at its Las Bambas copper mine in Peru by February 20, following a new and ongoing blockade of the road used by the company, which has already forced the Chinese miner to curtail operations.

Residents of the Chumbivilcas province have been blocking the main access to Las Bambas on and off since November 20. They demand jobs and economic contributions from the company, a unit of state-owned China Minmetals, which they say has failed to benefit residents despite its great wealth.

ELY, Minn. — This northwoods town is quiet and closed up for the winter — no throngs of tourists, the snowy streets largely empty. But there’s a range of emotions running among residents from hope and excitement to angry defiance.

The Biden administration’s decision last week to cancel the leases for the Twin Metals copper-nickel mine marked another dramatic turn in a dispute that has roiled this Iron Range community for decades: Does mining play a role in its future or is it firmly in the past?

Politics turning against copper mining – Freeport’s Adkerson – by Staff ( – January 26, 2022)

The copper market has cooled since touching record levels above $10,000 a tonne in May, but longer-term fundamentals for the bellwether metal remain bullish thanks to a global effort to electrify transport and shift to renewable power generation.

While there is consensus on demand growth, the supply side outlook is murky. Some 40% of the world’s copper production is controlled by just two countries – Chile and Peru – and political developments in South America are turning the tide against copper miners, Freeport-McMoRan CEO Rich Adkerson told investors in a conference call on Wednesday.

The Biden administration said Wednesday that it had canceled two mining leases that would have allowed a copper mine to be built near an area of pristine wilderness in Minnesota.

The Interior Department said it had determined that the leases, held by Twin Metals Minnesota, a subsidiary of the Chilean mining conglomerate Antofagasta, were improperly reinstated by the Trump administration in 2019.

Zambia has more than copper, and offers unexplored potential – by David Whitehouse (The Africa Report – January 19, 2022)

With billions of dollars worth of African gas, gold, copper and cobalt to hit the markets in 2022, industry players are focused on the next big deals. The election of a new government in Zambia in August 2021 has led to optimism that the country is the stand-out player in African minerals exploration for 2022.

“All eyes are on Zambia,” says Peter Major, director of mining at Mergence Corporate Solutions in South Africa. Major spoke in Cape Town in October as he prepared for a mining investment trip to Zambia. In the new president, Hakainde Hichilema, he says, the country has “a real businessman” in charge.

Copper Majors Are Taking Another Look at Argentina, McEwen Says – by James Attwood (Bloomberg News – January 20, 2022)

(Bloomberg) — Vast deposits and more welcoming policies have turned Argentina into a lithium hot-spot in recent years. Now the global copper industry is taking another look at the South American nation.

That’s the view of Rob McEwen, whose namesake company is drilling a property in San Juan province near the border with Chile. Called Los Azules, it’s attracted the attention of large producers such as Vale SA, Anglo American Plc and Barrick Gold Corp. as a potential acquisition, he said. All three companies declined to comment.
