The woolly mammoth's extinction is a complex and multifaceted topic that has been studied extensively by scientists and researchers.

According to various sources, climate change played a significant role in the extinction of the woolly mammoth.

Climate change wiped out woolly mammoths and Arctic megafauna, suggesting that the changing environmental conditions had a devastating impact on these species.

The warming climate reduced the woolly mammoth's habitats, and their population became restricted to Arctic islands.

The reduction in habitat and the loss of food sources due to climate change made it difficult for the woolly mammoths to survive.

The sharp climate change led to changes in vegetation, and the mammoths could not adapt quickly to the landscape changes.

The glaciers retreated and formed rivers, lakes, and marshes, replacing the mammoth pastures with trees and swamp plants.

This reduction in food sources and habitat loss ultimately led to the extinction of the woolly mammoths.

Climate change also reduced the genetic diversity and populations of the woolly mammoths, making them more vulnerable to extinction.

The woolly mammoths became extinct around 2000 BC, after living for roughly half a million years.

The woolly mammoths were similar in size to African elephants and thrived in grassland habitats.

However, the climate warming reduced their habitats, and human activity led to the loss of their habitat.

Human hunting also played a role in the extinction of the woolly mammoths, adding pressure to their already vulnerable population.

Humans hunted mammoths, and this hunting pressure, combined with the effects of climate change, ultimately led to their extinction.

The human activities reduced element transport by 90% through extinction, highlighting the significant impact of human activities on the environment.

The human-induced warming delayed the next ice age by 100,000 years, demonstrating the profound effects of human activities on the climate.

The humans raised the global average temperature by 1.8 degrees Fahrenheit, which had a significant impact on the environment and the woolly mammoths.

Some sources suggest that human activity was not the primary cause of the woolly mammoth's extinction.

However, other sources argue that humans played a key role in the disappearance of large mammals, including the woolly mammoths.

Without humans, the Earth would have more diverse large mammals, suggesting that human activities had a significant impact on the extinction of these species.

The woolly mammoths survived several ice ages previously, but the rapid climate change led to food scarcity, and they could not adapt to the changing landscape.

The isolated populations of woolly mammoths caused low genetic diversity, making them more vulnerable to extinction.

The climate change destroyed the mammoths and megafauna, highlighting the significant impact of climate change on the environment.

The extinction of the woolly mammoths occurred at the end of the Pleistocene, a period of significant climate change.

In conclusion, the extinction of the woolly mammoths was a complex and multifaceted process that was influenced by both climate change and human activities.

The effects of climate change, including the reduction in habitats and food sources, combined with the pressure of human hunting, ultimately led to the extinction of the woolly mammoths.

The study of the woolly mammoth's extinction provides valuable insights into the impact of human activities on the environment and the importance of preserving biodiversity.

The woolly mammoth's extinction is a complex and multifaceted topic that has been studied extensively by scientists and researchers.

Content: How would the earth be different if modern man did not exist?
The Libyan Observatory Newspaper
LATEST NEWS
The human footprint can be seen across the planet today, from the towering skyscrapers that define our modern capitals to the pyramids and other ancient relics from our past.
Human activity also represents the sprawling open fields of agriculture, the roads that connect everything together.
But what would the world look like if humans didn ’ t exist before?
Some scientists paint a picture of a pure wilderness and an abundance of species, from fashionable to uncommon.
Trevor Worthy, a paleontologist and assistant professor at Flinders University in Australia, told Live Science: “I think it would be a much more vegetative place with a wealth of animals, of great size, spread across all continents except Antarctica. ”
A world without modern humans may also mean that our extinct human relatives, such as Neanderthals, will still exist.
And, of course, they would have changed the scene as well.
Humans shaped the world at the expense of many species, from the dodo (Raphus cucullatus) to the Tasmanian tiger (Thylacinus cynocephalus), which pushed us to extinction through activities such as hunting and habitat destruction.
The rate of extinction on Earth today is more than 100 times what it would have been without humans, according to the most conservative estimates, and has not been higher since the Cretaceous and Paleogene (K-Pg) extinction event that wiped out about 80% of animal species, including non-floating dinosaurs, 66 million years ago.
In other words, humans collided with the planet like an asteroid, and the dust continues to settle as wildlife continues to deteriorate.
“My great-grandfather was able to see herds of thousands of parrots in the landscape, my grandfather saw a hundred flocks, my father saw little and I ’ m lucky if I could see two in the woods, ” said Worthy.
The human-driven decline of nature suggests that Earth would be a more wild place without us, with some lost giants, such as moas, standing out the most.
This group of ostrich-like birds, some of which extend up to 11.8 feet (3.6 m) in New Zealand, evolved over millions of years.
Within 200 years of humans reaching their land 750 years ago, all nine species of moa have disappeared, along with at least 25 other vertebrate species, including the giant Haast eagles (Hieraaetus moorei) that hunted moa, according to Worthy.
The giant moa and the Haast vultures are recent examples of large animals whose eventual extinction is linked to human activities, such as unsustainable hunting and the introduction of invasive species into new habitats.
They are also indicators of what our relationship with large animals might be like elsewhere.
The survival of large animals is crucial to speculate on the existence of a land without humans, as these monsters have a significant impact on the landscape.
– Serengeti System
Soren Furby, senior lecturer in zoology at the University of Gothenburg in Sweden, believes that humans played a key role in the disappearance of many large mammals thousands of years ago.
He led a 2015 study, published in the journal Diversity and Distributions, which suggested that without humans, the Earth would be much like the contemporary Serengeti system, an African ecosystem teeming with life.
In this scenario, extinct animals similar to those found in Serengeti today – including elephants, rhinos and lions – would live across Europe.
For example, instead of African lions (Panthera leo), there are still cave lions (Panthera spelaea), a slightly larger species that lived in Europe until about 12,000 years ago.
Meanwhile, the Americas will be home to relatives of huge elephants and bears, along with unique species, according to Forby.
"In a world without humans, there will be much more diversity than large mammals, and if you see a greater diversity than large mammals, you tend to see a more open habitat," Forby said.
Elephants and other large animals are well identified when finding food, and will not tolerate unnecessary obstacles.
“If you ’ re old enough, it might be easier to knock on a tree and eat fresh leaves on top of it, ” Forby said.
But also, if there are a large number of large mammals, there is a tendency to have fewer wooded plants in the first place, he said.
Large animals, such as elephants, are known as megafauna.
During the last ice age (2.6 million to 11,700 years ago), the world was rich in megafauna, but most of them died at the end of the ice age, or in the thousands of years since.
For example, about 38 genera of large animals went extinct in North America at the end of the last ice age, according to a 2020 study published in the journal Proceedings of the National Academy of Sciences.
Over the past century, scientists have debated whether natural climate changes or human activities, such as overfishing, are the main reason for the decline of these large animals.
A 2021 study published in Nature concluded that climate change ultimately wiped out the woolly mammoths (Mammuthus primigenius) and other Arctic megafauna that survived the end of the ice age.
However, humans hunted mammoths.
Scientists who believe humans may have been the main factor in their extinction, such as Forby, argue that mammoths survived climate change before humans appeared and would probably survive to this day had it not been for the added pressure humans placed on them.
Christopher Dottie, an associate professor and ecologist at Northern Arizona University, is modeling how past and present large animals transport seeds and nutrients through eating and defecating.
His work indicates that the transport of elements such as phosphorus, calcium and magnesium, which are important for life, was reduced by more than 90% through the extinction of large animals.
Dotti hypothesizes that without humans, elements would be evenly distributed across the landscape.
This means more fertile soil, which makes ecosystems more productive.
Humans tend to group elements together through practices such as farming and creating fenced areas, so that these areas become less fertile over time compared to terrestrial systems, according to Dauty.
Greater fertility means that plants can devote their resources to more fruit and flowers, so that the world looks more vibrant and feeds more animals.
While it is difficult to determine how humans and megafauna have influenced climate change for thousands of years with evidence obscured over time, it is much easier to judge our impact on Earth ’ s climate today.
Through global warming, caused by activities such as burning fossil fuels, humans have raised the global average temperature by about 1.8 degrees Fahrenheit (1 degrees Celsius) since the beginning of the 20th century.
Therefore, the Earth would have been at least colder without us.
A 2016 study published in the journal Nature concluded that human-induced warming would delay the next ice age by at least 100,000 years.
And it wasn't due for another 50,000 years, though, even without human delay, so it's unlikely that Earth would be in the middle of another ice age today if we didn't exist.
Humans are inevitable.
Scientists aren ’ t sure why Neanderthals went extinct about 40,000 years ago, but because they mate with Homo sapiens, parts of their DNA are found in some of us.
There were probably multiple causes of Neanderthal death, but we're a prime suspect.
Chris Stringer, a professor and research leader in human origins at the Natural History Museum in London, believes competition for resources was a factor in the disappearance of Neanderthals.
“If we weren ’ t around, if we hadn ’ t come to Europe 45,000 or 50,000 years ago, I think they ’ d probably stay here, ” he told Live Science.
According to Stringer, Neanderthals lived a complex life in Europe, similar to modern humans, but they had difficulty adapting to climate change and were relatively few in number, with low genetic diversity.
This is bad news for any species, as it is a sign of inbreeding and ill health.
Stringer said Neanderthals were probably “already in trouble, and when modern humans got there too, I think that ’ s probably what pushed them to the edge. ”
Scientists are still learning about at least one human lineage that lived around the same time as modern humans and Neanderthals: Denisovans.
This lineage appears to be closer to Neanderthals than modern humans in genes and appearance, but it can be distinguished from Neanderthals with very large molars.
There is evidence of DNA in current humans living in places like New Guinea in Oceania — a finding that suggests Denisovans were in Southeast Asia interacting with ancestors of modern humans who later settled in the East, according to a 2012 study published in the journal Science.
These Denisovan interactions, along with fossil evidence, suggest that they had a larger geographic range than Neanderthals, encompassing a variety of environments and, therefore, arguably, were more adaptive than Neanderthals.
DNA evidence also suggests that Denisovans may have had greater genetic diversity than Neanderthals, according to Stringer.
Stringer said: “There ’ s no reason why Neanderthals or Denisovans shouldn ’ t do it eventually, given enough time. ”
He added that they may have overcome any potential intellectual deficiency, which is not clear to them, through evolution.
So maybe the world won ’ t look completely different after all.
Likewise, they could have made the same mistakes we have made since then.
So, global warming could have been here, but with Neanderthals or Denisovans leading it, not us.

Content: Woolly mammoth (Mammuthus primigenius)

The most famous of the 10 mammoth species known to have existed is undoubtedly the woolly mammoth. Standing at around the same size as today’s African elephants, this magnificent animal roamed the northern hemisphere for roughly half a million years, becoming extinct by around 2000 BC.

The reasons for the woolly mammoth’s demise are multifaceted. As the climate warmed at the end of the last Ice Age, and forests spread across the northern hemisphere, the grassland habitats in which the animal thrived were drastically reduced. This, combined with hunting pressures from humans, meant the woolly mammoth population ended up being restricted to just a couple of islands in the Arctic Ocean near Siberia and Alaska.

Some scientists hope to bring the woolly mammoth back from extinction, but with African and Asian elephant populations still facing a huge range of threats, many believe that our focus should be on preserving those animals instead.

Dodo (Raphus cucullatus)

For a large bird species that only became extinct relatively recently, we know surprisingly little about the dodo and its behaviours. In fact, there is just one near- complete dodo skeleton with bones from one bird, and there is only one specimen that contains soft tissue.

What we do know is that the dodo was restricted to Mauritius, an island in the Indian Ocean off the eastern coast of Madagascar and part of the Mascarene Archipelago, and was a relative to doves and pigeons. It’s thought that natural selection caused the animal to evolve into a flightless bird, with the species no longer needing to fly on an island with no predators.

However, when humans – and the animals they brought with them – first came to Mauritius in the 16th century, the dodo became extremely vulnerable. As well as being hunted for meat, it suffered from habitat loss and the predation of its eggs, resulting in its extinction by c1680.

Thylacine (Thylacinus cynocephalus)

Also known as the Tasmanian tiger or Tasmanian wolf, the thylacine was a carnivorous mammal originally found in Australia and New Guinea. Despite being similar in appearance to the domestic dog, it was actually a marsupial – a group of mammals that also includes kangaroos, koalas, wombats and opossums – and had a pouch.

Once widespread, the thylacine became extinct on the Australian mainland no less than 2,000 years ago, although the reasons for this are unknown. The species then became restricted to the island of Tasmania, off the south coast of Victoria, with between 2,000–4,000 individuals remaining when the British arrived in the early 19th century.

Eventually, the thylacine was persecuted as it was deemed a threat to livestock. The last known captive individual died from exposure at a zoo in Hobart in 1936 after being accidentally left out overnight. It’s thought that the last wild thylacines died in the 1960s, but that hasn’t stopped persistent rumours over the species’ continued survival.

Great auk (Pinguinus impennis)

Despite being similar in colouration and shape and bearing the genus name Pinguinus, the great auk wasn’t a relative of penguins, but was instead a member of the same family as puffins and guillemots.

Once a relatively common species in the North Atlantic, it bred on remote rocky islands such as Funk Island off the coast of Newfoundland, which was described by one 18th- century sailor as being “entirely covered with those fowls, so close that a man could not put his foot between them.”

However, exploration of the North Atlantic seas by European sailors spelled danger for the flightless seabird, with overharvesting of its eggs and adults for meat, feathers and body parts dramatically reducing the population. Attempts were made to protect the great auk, but that only increased its worth to collectors.

Sadly, the last breeding pair were killed and their single egg accidentally crushed by fishermen on Eldey Island, Iceland, on 3 July 1844.

Xerces butterfly (Glaucopsyche xerces)

Named after the Persian kings Xerxes I and Xerxes II (whose names are sometimes spelled ‘Xerces’ in France), this diminutive blue butterfly species lived among the coastal sand dunes of the San Francisco Peninsula, where its caterpillar preferred to feed on a single plant species.

However, urban development resulted in the loss of the plant, which could not survive in disturbed soil, and thus the loss of the Xerces blue in the 1940s – the first example of a butterfly becoming extinct due to human activity in North America.

Later, the Xerces Society, a non-profit conservation organisation established in 1971, was named in memory of the lost invertebrate.

For a while, there was uncertainty as to whether the Xerces blue was a distinct species or a subspecies of another blue butterfly. However, a scientific paper published in 2021 examined the DNA of a museum specimen collected in 1928 and proved that it was indeed a distinct species.

Passenger pigeon (Ectopistes migratorius)

The passenger pigeon was one of the most abundant pigeon species on the planet. Native to North America, it was called jahgowa by the Seneca Tribe, which translates to “big bread”, as it was a source of food by the Seneca and the rest of the Haudenosaunee people. Despite this, the hunting of the species was carefully regulated by rules set by each tribe.

However, after colonisation by the Europeans, hunting of the passenger pigeon increased and gradually became more industrial and commercialised. As the population declined, the species then became vulnerable to further pressures such as habitat loss and predation by other animals.

The last living passenger pigeon was a female named Martha, who was kept at Cincinnati Zoo in Ohio. She died on 1 September 1914 – one of the few times we have known the absolute date of a species’ extinction. Her death contributed to the creation of the US Migratory Bird Treaty Act, which requires permits to hunt some migratory bird species.

Golden toad (Incilius periglenes)

So-named for the brilliant yellow-orange colouration of the male (the female was black with yellow and red patterning), the golden toad has become a poster child for extinctions connected to the climate crisis.

Found in the Monteverde Cloud Forest of Costa Rica, the amphibian spent most of the year underground. It only emerged for a few days each April, with males fighting with each other around pools of rainwater in order to mate with females.

In 1987, roughly 1,500 golden toads were observed. However, the following year, only 10 toads were found, and in 1989, just one male. That one male was the last golden
toad ever seen, and the species was officially declared extinct in 2004.

While the exact cause of extinction is unknown, the climate crisis – combined with habitat loss and an infectious disease called chytridiomycosis – are all thought to have played a part.

Baiji (Lipotes vexillifer)

The baiji was a freshwater dolphin that lived in the Yangtze River in China, the third-longest river in the world. Although still listed as ‘Critically Endangered’ on the International Union for the Conservation of Nature’s Red List, having last been assessed in 2017, the species is considered extinct by conservationists. In fact, both the last confirmed sighting of a wild individual and the death of the last captive individual occurred in 2002.

The Yangtze River is also home to the Yangtze finless porpoise, the only freshwater porpoise in the world. Like the baiji, its existence is currently threatened by overfishing, shipping traffic and noise pollution.

However, the 2017 suspension of sand mining in Dongting Lake – a flood basin of the Yangtze in China’s Hunan province – has seen the finless porpoise return to areas that it had previously been avoiding.

Pinta Island giant tortoise (Chelonoidis nigra abingdonii or Chelonoidis abingdonii)

While there is debate about whether the giant tortoises of the Galápagos Islands are subspecies of the same species or a completely different species altogether, one thing is certain: Lonesome George was the last of his kind.

George was a Pinta Island tortoise, a species (or subspecies) that was already thought to have been extinct until he was discovered alone on the island that gave George and his former companions their collective name.

There were attempts to find other Pinta Island tortoises, and to mate him with closely related females, but to no avail. He died in 2012 of natural causes when he was around 100 years old.

Curiously, scientists believe it might be possible to bring back the Pinta Island tortoise, or at least a closely related version. Researchers have discovered hybrid tortoises with Pinta Island tortoise genes on nearby Isabela Island, with their Pinta Island ancestors having been moved there by whalers and pirates.

The cause of the extinction of mammoths
Scientists have found that mammoths died out due to climate change

An international team of researchers found that the cause of the extinction of mammoths in Siberia was primarily a sharp climate change, not human activity.
The article is published in the journal Nature.
Woolly mammoths became extinct only about four thousand years ago.
They were not only the main source of meat of ancient people – the latter made from their bones the basis for dwellings, from their tusks made harpoons and even musical instruments.
Therefore, there is a widespread theory that the main cause of extinction was humans.
Researchers from the Institute of Earth Sciences of St. Petersburg State University together with colleagues from the UK, Denmark, China, Norway and the United States decided to restore the appearance of the tundrosteppe, which was inhabited by mammoths.
To do this, they using the shotgun method — obtaining from a random massive sample of cloned fragments of the original sequence — analyzed the DNA of ancient plants and animals collected from 535 different places in the Arctic, where the mammoth lived, over 20 years.
They also analyzed the DNA of more than 1,500 modern plants and animals.
Researchers were able to map the distribution of populations of mammoths and other representatives of the megafauna of the tundrosteppe.
They saw that over time their populations and genetic diversity became smaller and smaller — making survival increasingly difficult.
With the end of the Pleistocene about 12 thousand years ago and the accompanying retreat of glaciers and the formation of rivers, lakes and marshes, vegetation has decreased in volume, and it has become insufficient to maintain the previous level of populations.
As the climate warms, trees and swamp plants have taken the place of former mammoth pastures.
“We have shown that climate change, in particular rainfall, has directly led to changes in vegetation.
According to our models, people did not have any influence on them [mammoths], ” said the first author of the work, a researcher at the University of Cambridge Yuchen Wang.
However, the extinction of mammoths was influenced not only by the warming of the climate itself.
“His speed was the last nail in the lid of the coffin – they (megafauna tundrosteppe – approx.
“Tape.ru ”) could not adapt quickly enough, when the landscape radically changed and food was not enough, ” said the head of the scientific group, Professor of Copenhagen and Cambridge universities Eske Willerslev.

The Hungry Death of Great Animals
It would seem that mammoths existed for millions of years and survived several ice ages.
That is, climate change did not affect them critically.
But as soon as they encountered humans, they began to die out.
Finally, we were able to prove that the problem was not only climate change, but also the speed of these changes.
This was the last nail in the coffin – the mammoths could not adapt quickly enough when the landscape changed dramatically and food became scarce.
- says the author of the study Eske Willerslev, a professor at the University of Cambridge and director of the Center for Geogenetics of the Lundbeck Foundation at the University of Copenhagen.
The team, led by Prof. Willerslev, sequenced the DNA of plant, animal, and their fossilized excrement, coprolites.
The selection of these samples lasted about 20 years and allowed us to fully understand why the majestic animals died out.
After the end of the last cooling, the glaciers began to melt.
The environment quickly became quite humid, leading to a chain change in flora.
Typical mamut habitats and pastures became increasingly swampy and vegetation changed accordingly.
As a result, there is simply no food left typical for animals.
From birth to death: scientists have fully investigated the life path of the mammoth
Giants did not have time to adapt to rapid changes, so the total number of mammoths was constantly declining.
Because of this, isolated and partially isolated animal populations arose, which already caused little genetic diversity.
It is clear that all this did not positively affect the chances of survival.
Scientists say climate change is critical.
When such changes destroyed mammoths and probably another megafauna.
Today, we live in a time when the average temperature on the planet is rising again, so we need to take this “harsh lesson ” seriously.

Greenland has rare earth minerals with potential to power clean energy transitions, and the estimated location of deposits is Disco Island and Noswak Peninsula.

The country is rich in minerals, including rare earth minerals, and has been identified as a potential hot spot for coal, copper, gold, and zinc.

The Geological Survey of Denmark and Greenland has conducted assessments of the mineral deposits, and ice melting due to the climate crisis is creating new extraction opportunities.

The Tanbreez mine, for example, contains 19 million tons of rare earth oxides, with 30% being heavy rare earth elements.

Several countries and corporations have expressed interest in extracting and exploiting these minerals, including billionaires like Bezos, Bloomberg, and Gates, who are funding mineral searches.

Kobold Metals and Bluejay Mining are partnering for extraction, and China has expressed interest in Greenland's iron ore and rare earth minerals [1].

The Canadian company, New Performance Materials, has been granted a license to mine rare metals in Greenland, and AEX Gold has exploration licenses in South Greenland for gold mining [4].

The Greenland government is supportive of mining projects and has a favorable legal framework and robust infrastructure in place.

However, mining rare earths can be difficult and harmful to the environment, and a factory is needed to separate the rare earths from rocks, with equipment costs estimated at $40 million.

Despite these challenges, several companies are moving forward with extraction plans, including NEO, which aims to build a permanent magnet manufacturing plant in Estonia.

Greenland has rare earth minerals with potential to power clean energy transitions, and the estimated location of deposits is Disco Island and Noswak Peninsula.

CNN reports that some of the world ’ s wealthiest people are funding large treasure hunts using helicopters and signal transmitters on Greenland ’ s west coast.
The climate crisis is causing Greenland ’ s ice to melt at unprecedented rates, ironically creating an opportunity for investors and mining companies looking for a treasure trove of important minerals capable of powering clean energy transitions.

Search for minerals in Greenland
Many billionaires, including Jeff Bezos, Michael Bloomberg and Bill Gates, are betting that what lies beneath the surface of the hills and valleys of Disco Island and Greenland ’ s Noswak Peninsula are important enough minerals to power millions of electric vehicles.
Speaking to CNN, Kobold Metals CEO Kurt House said: “We are looking for a deposition that will be the largest or second largest nickel and cobalt deposition in the world. ”
The disappearance of Arctic ice – both on land and in the ocean – highlights a unique dichotomy: Greenland is the zero point for the effects of climate change, but it could also be the zero point for the search for the minerals needed to provide solutions to this crisis.
For their part, representatives of Kobold Metals, a California-based mineral exploration company, said the billionaires ’ club is supporting the company financially.
Bezos, Gates and Bloomberg did not respond to requests from CNN for comment on the news, and Kobold Metals is partnering with Bluejay Mining to find precious and rare metals in Greenland, which are essential for building the electric vehicles and huge batteries needed to store renewable energy.
The Geological Survey of Denmark and Greenland said Greenland could be a hot spot for coal, copper, gold, rare earth elements and zinc.
The Greenland government has conducted several assessments on ice-free land and is aware of the country ’ s “ability to diversify the national economy through mineral extraction, ” the agency said.

The country is rich in minerals, including rare earth minerals, and has been identified as a potential hot spot for coal, copper, gold, and zinc.

The Geological Survey of Denmark and Greenland has conducted assessments of the mineral deposits, and ice melting due to the climate crisis is creating new extraction opportunities.

The Tanbreez mine, for example, contains 19 million tons of rare earth oxides, with 30% being heavy rare earth elements.

Greenland to mine rare earths in 2024
According to the German "Economic Weekly" reported that a mining company has obtained permission from the Greenland government to mine rare earths on the island.
The company said production could begin next year.
Tanbreez Mining, a mining company, plans to mine rare earths in Greenland next year, according to the Economic Weekly.
“We can start production next year, ” said Greg Barnes, a geologist and owner of the company. Greenland ’ s deputy minister for minerals confirmed to the journal that a mining licence had been issued.
Barnes said the Tanbreez mine "contains more than half of the world's rare earth resources" and has 19 million tons of rare earth oxides.
Of these, 30% are highly favored heavy rare earth elements.
Rare earth contains a total of 17 kinds of metal elements, the properties of each metal are different.
Each metal has a unique industrial value.
Some of them are irreplaceable.
They are used, for example, in the manufacture of electric vehicles or wind turbines.
Last year, about two-thirds of Germany ’ s rare earths came from China. Mining such as rare earths is difficult and often harmful to the environment, as rare earths are often associated with iron ore, and the chemical process of refining often requires the use of acidic substances.
What is Rare Earth?
Barnes, owner of Tanbreez Mining, told Economic Weekly that to start mining for rare earths in Greenland, a factory would be needed to separate rare earths from heterosexual rocks.
Currently there are only such factories in Russia and China.
But one such plant will be built in the United States in the coming months.
There are also plans to build a factory in Europe.
Thanks to technological advances, the equipment that separates rare earths currently costs only $40 million.
According to Barnes, China paid 1.7 billion U.S. dollars for the equipment 13 years ago.
In January, Swedish state-owned mining company LKAB announced the discovery of Europe ’ s largest rare earth deposit to date.
But the company said it would take 10-15 years for the rare earth mine, located in Kiruna in northern Sweden, to be available to the market.

What does Greenland's Tanbreez mine contain?

30% of oxides are highly sought after heavy rare earth metals

Several countries and corporations have expressed interest in extracting and exploiting these minerals, including billionaires like Bezos, Bloomberg, and Gates, who are funding mineral searches.

Kobold Metals and Bluejay Mining are partnering for extraction, and China has expressed interest in Greenland's iron ore and rare earth minerals [1].

Title:

Content: The government of Greenland, which is located in the Arctic, said on Monday it had revoked the license of a Chinese mining company to mine an iron ore deposit near the capital, Nuuk.
The move has dealt a blow to efforts by Chinese companies to gain a foothold in the resource-rich Arctic region.
China ’ s General Nice took control of the Isua mine in 2015, replacing bankrupt London Mining.
Junan became the first Chinese company to acquire mining rights in Greenland.
Greenland is an autonomous region of Denmark and is rich in minerals.
As a result of the warming climate, waterways have been opened, allowing the resources of the Arctic Island to be developed and utilized.
The Greenland government pointed out that the mine was idle and Junan did not pay the agreed guarantee and therefore withdrew its license.
Once Junan returns the license, Greenland will re-offer it to interested companies.
At present, the government of Greenland has asked Junan to return all the geological data, pay the remaining 1.5 million Danish kroner (about $226,000) of the deposit, and clean up the mine.
The London mine, which was granted mining rights in 2013, initially planned to employ 2,000 Chinese workers to mine, with a goal of supplying about 15 million tonnes of iron ore to China each year.
Greenland banned uranium mining this year, blocking mining in the Kuannersuit region, one of the world ’ s largest rare earth mines and partly owned by a Chinese company.
Junan tried to buy an abandoned naval base in Greenland from Denmark in 2016, but sources told Reuters at the time that the Danish authorities had rejected the proposal for security reasons.

What countries are invested in Greenland Minerals corp?

The Canadian company, New Performance Materials, has been granted a license to mine rare metals in Greenland, and AEX Gold has exploration licenses in South Greenland for gold mining [4].

Title:

Content: AEX Gold aims to invest in Greenland through its new gold mining project

Traditionally known for its fishing and hunting industries, Greenland is fast becoming the next significant area of exploration for mining businesses. The largest island in the world, Greenland remains one of the least populated areas worldwide with 56,000 citizens, and it has sought to attract local and foreign investment across a number of new projects.

The island’s current position remains complex. A sovereign government, it is positioned under the Danish kingdom who provide grants to support its local economy. To further its independence and bolster its economy to create increased tax revenue, Greenland has embraced the exploration of new mining projects as well as utilising all the renewable and local resources it has to offer.

Rich in rare-earth minerals, gold, iron-ore, uranium, in addition to hydro and wind power, Greenland’s favourable legal framework and robust infrastructure, particularly in South Greenland, have factored into AEX Gold’s vision to explore through its Greenlandic subsidiary, Nalunaq Gold Mine, situated in the Nanortalik Gold belt, Southern Greenland.

Acquiring an existing Exploitation Licence in 2015, the company is at the advanced exploration stage of its Nalunaq property, including the previously operating Nalunaq Gold Mine.   It also holds Exploration Licences at the early exploration stage Vagar and Tartoq properties.

Hosting a high-grade NI 43-101 compliant gold resource estimate of 263k oz (inferred) at 18.7 g/t and a number of regional exploration targets, AEX Gold has undertaken three years of exploration at Nalunaq, developing an updated geological model and an extension of the main vein strike length up to 1km.

“The government is very supportive, so it's about having a sound exploration strategy. We are very much focused on that, as we have an asset package that we think we can grow and create a lot of value,” explains Chief Executive Officer, Eldur Olafsson.

Originating from Iceland, Olafsson has gained extensive experience of the local geography. Focusing on mining projects in Greenland since 2012, he has analysed the country’s potential against the backdrop of environmental responsibilities and associated legalities with partner SRK Exploration Services. Through this process, the business has turned its attentions solely towards gold exploration.

“The known gold deposits in Greenland are in an area where the climate is mild and, given our experience, logistics are relatively easy. Gold opportunities are easier to finance than larger base metals projects and our perception was that we could fully fund projects like these through our support here in Iceland and in the UK market,” he explains.

“We started looking for opportunities in the South Greenland Gold Province and became aware of this historically producing mine. We were attracted by the extremely high-grade potential of the resource and the fact that the project had significant infrastructure in place.  We believed there were significant opportunities to materially improve the mining operation that had been run by previous operators.”

Extensive exploration

Throughout the exploration of high-grade resources, Olafsson is proud to remain hands on and is regularly seen on site. By undertaking various technical studies, AEX has gained the ability to comprehensively analyse similar types of assets with potential.  After acquiring the Nalunaq project in 2015 the company has continued to expand its portfolio. Whilst Nalunaq encompasses the required licence to explore and recommence production at the old gold mine, they own the larger Vagar exploration licence, situated a few kilometres to the west of the mine, where AEX believes the ground is prospective for the discovery of further Nalunaq-type deposits.  In addition, they also own the early stage Tartoq Project to the North West of Nalunaq. Each licence area is at a different stage of exploration which supports AEX’s aim of having a continuous pipeline of projects being brought into production.

“We have a total of 690sqkm of licences in south Greenland and we're the only active listed gold company in Greenland. Previous operators undertook very little forward-looking exploration once the mine was in production.  It's a very under-explored region so we intend to recommence production within the next two years at Nalunaq in order to support our exploration in the larger licences in the next 5-10 years,” he says.

“Iceland is a short distance from Greenland, so logistically it’s good for us. Additionally, in Iceland you need to be really self-sufficient, and the same can be said for those in Greenland. We don't have as many people or the multitude of services that you would have in other countries which encourages you to think creatively,” he adds.

Consequently, the company has sought to maximise efficiency whilst keeping costs down, yet all the time adding increased value across its operations.

By acquiring a high-grade deposit, less material is needed to be broken down, lowering AEX Gold’s carbon footprint. Everything taken out of the mine from underground will be processed and shipped out to a different processing facility, or processed on site adhering to the current environmental guidelines. Historically, electricity has been generated through the use of traditional fossil fuels, something which is steadily changing throughout Greenland.

“We're using oil to put in generators or to power mobile mining equipment which is high cost both in monetary and environmental terms.   Greenland currently has five hydroelectric power plants and they are looking at building more in south Greenland,” says Olafsson.

Seeing huge opportunities, he explains that the use of hydropower and wind power would complement AEX Gold’s operations, not only in its existing exploration activities, but with the implementation of an electric mining fleet with electricity being obtained from local renewable resources.

Providing local opportunities

In the future, it will be essential for Greenland to gain further revenue to unlock opportunities and services for its citizens. This is something Olafsson believes that AEX Gold can help with due to its knowledge of Iceland as it has many similarities to Greenland and has been through a period of comparable change.

“Greenland is in a similar position to Iceland not so long ago. Iceland didn't have a high education rate and wasn’t wealthy compared to other European countries, with economic and cultural activities that were very insular. We are now at the highest level of all parameters in terms of education, wealth per family, etc. and this has stemmed from improving the breadth of schooling and creating opportunities for people to grow and develop outside of the traditional areas of agriculture and fisheries.

“Our aim is that the majority of employees will be Greenlandic, but it will take time. Greenland has a large number of people competing for jobs in the fisheries and tourist centres. It is important that Greenlanders are able to access programmes that will allow them to consider other career options. In Iceland we are importing a lot of people to work in different industries in our country because we don't have enough people. This might be the case for Greenlanders as well if the anticipated growth of the Mining Sector materialises but we want to ensure that, where possible, we use local people first before looking elsewhere.

“The Greenlandic Government provides good support for those who seek education.  There are an increasing number of Greenlandic students attending Danish Universities so that now, for example, we are seeing well qualified Greenlandic geologists available for employment.  There has been a Mining School at Sisimiut for the last 10 years which provides local qualified labour who can take advantage of opportunities in the Mining sector.  You need skilled labour and as we own a mine that was in production for 10 years previously, there is a fair bit of local knowledge that we have been able to use during our exploration work and which we are keen to utilise going forward,” he says.

“We are creating revenue for local communities, creating highly skilled jobs, and are providing benefits where local communities can live better lives and grow as individuals. We need to create opportunities for young people.”

Additionally, by working with local businesses as well as those who have been operating in Greenland for some time, AEX has made a conscious effort to hire companies which can support its growth. AEX have therefore acquired a longstanding relationship with Cartwright Drilling, due to the company’s extensive experience in Greenland and subsequent knowledge of the island’s government systems, processes and practices.

Planning to mine high-grade resources using significant infrastructure already in place, AEX Gold holds extensive licences managed by an experienced team. Previous operations produced between 50,000 to 100,000 ounces a year at 15.4 grams/ton produced and this has provided a benchmark for the company, who will utilise this cash flow to explore the wider region in the long-term.

“We have a five-year plan where we want to get into production at Nalunaq and use the cash generated to fund exploration in the wider district.   We envisage investing a significant amount in exploration assets to provide a portfolio of different deposits that we can bring into production. We are creating a company that has a long-term mission in Greenland to build up local know how to support our aim of ramping up to very profitable production across a number of projects,” notes Olafsson.

“It will create a dramatic effect on the local community and hopefully be a springboard for unlocking much larger potential in Greenland. There are plenty of deposits that have been found, but you have to be able to develop them. You can only do that that with support and cooperation from the local people who believe in your vision.”

Greenland is rich in rare earth minerals, with an estimated 19 million tons of rare earth oxides, making it a significant player in the global market.

The country's rare earth deposits are primarily located in the Kuannersuit region, which is home to one of the world's largest rare earth mines.

According to recent reports, Tanbreez Mining is set to mine rare earths in Greenland in 2024, with the Tanbreez mine containing over half of the world's rare earth resources.

The extraction of rare earths is a complex and challenging process, often harmful to the environment, which may pose significant difficulties for mining companies operating in the region.

Despite these challenges, several countries and corporations have expressed interest in extracting and exploiting Greenland's rare earth minerals, including China, which has been actively seeking to acquire mining rights in the country.

In 2015, China's General Nice controlled the Isua mine in Greenland, and Junan acquired mining rights in the country, although Denmark rejected Junan's proposal to buy a naval base in 2016.

Greenland has since revoked Chinese mining company licenses near Nuuk, and the government has asked Junan to return geological data, indicating a shift in the country's approach to foreign investment in the mining sector.

The Canadian company, NEO, has been granted a license to mine rare metals in Greenland, and Toronto's New Performance Materials has obtained an exploration license in the country.

NEO plans to explore and develop the Surfertog project in Greenland, which contains neodymium and praseodymium mineral deposits, essential for the production of electric vehicles and renewable energy technologies.

The company aims to build a permanent magnet plant in Estonia to supply European manufacturers, highlighting the growing demand for rare earth minerals in the region.

Other companies, such as Kobold Metals, are searching for nickel and cobalt deposits in Greenland, partnering with Bluejay Mining for mineral extraction.

The Geological Survey of Denmark and Greenland has identified potential hotspots for mineral deposits, and the government is assessing ice-free land for mineral extraction, which could diversify Greenland's national economy.

The country's favourable legal framework and robust infrastructure, including five hydroelectric power plants, make it an attractive destination for mining companies.

AEX Gold has exploration licenses in South Greenland, covering an area of 690 square kilometers, and the company aims to use hydropower and wind power for its operations.

The Greenlandic Government provides support for education and local employment, which could help to mitigate the social and environmental impacts of mining activities.

The estimated value of Greenland's rare earth minerals is not publicly available, but the country's significant deposits and growing demand for these minerals make it an important player in the global market.

The ease of extraction is a significant challenge, with equipment costs for separating rare earths from rocks currently estimated at $40 million.

Despite these challenges, the potential rewards of extracting Greenland's rare earth minerals make it an attractive opportunity for companies and countries seeking to secure a stable supply of these critical minerals.

China's interest in Greenland's iron ore and rare earth minerals is likely to continue, given the country's significant deposits and strategic location.

The development of rare earth mining in Greenland is expected to have significant economic and environmental implications, and the government will need to carefully balance the benefits of mining with the need to protect the country's unique and fragile environment.

Overall, Greenland's rare earth minerals represent a significant opportunity for companies and countries seeking to secure a stable supply of these critical minerals, but the challenges of extraction and the need to protect the environment must be carefully considered.

Greenland is rich in rare earth minerals, with an estimated 19 million tons of rare earth oxides, making it a significant player in the global market.

“The government is very supportive, so it's about having a sound exploration strategy. We are very much focused on that, as we have an asset package that we think we can grow and create a lot of value,” explains Chief Executive Officer, Eldur Olafsson.

Originating from Iceland, Olafsson has gained extensive experience of the local geography. Focusing on mining projects in Greenland since 2012, he has analysed the country’s potential against the backdrop of environmental responsibilities and associated legalities with partner SRK Exploration Services. Through this process, the business has turned its attentions solely towards gold exploration.

“The known gold deposits in Greenland are in an area where the climate is mild and, given our experience, logistics are relatively easy. Gold opportunities are easier to finance than larger base metals projects and our perception was that we could fully fund projects like these through our support here in Iceland and in the UK market,” he explains.

“We started looking for opportunities in the South Greenland Gold Province and became aware of this historically producing mine. We were attracted by the extremely high-grade potential of the resource and the fact that the project had significant infrastructure in place.  We believed there were significant opportunities to materially improve the mining operation that had been run by previous operators.”

Extensive exploration

Throughout the exploration of high-grade resources, Olafsson is proud to remain hands on and is regularly seen on site. By undertaking various technical studies, AEX has gained the ability to comprehensively analyse similar types of assets with potential.  After acquiring the Nalunaq project in 2015 the company has continued to expand its portfolio. Whilst Nalunaq encompasses the required licence to explore and recommence production at the old gold mine, they own the larger Vagar exploration licence, situated a few kilometres to the west of the mine, where AEX believes the ground is prospective for the discovery of further Nalunaq-type deposits.  In addition, they also own the early stage Tartoq Project to the North West of Nalunaq. Each licence area is at a different stage of exploration which supports AEX’s aim of having a continuous pipeline of projects being brought into production.

“We have a total of 690sqkm of licences in south Greenland and we're the only active listed gold company in Greenland. Previous operators undertook very little forward-looking exploration once the mine was in production.  It's a very under-explored region so we intend to recommence production within the next two years at Nalunaq in order to support our exploration in the larger licences in the next 5-10 years,” he says.

“Iceland is a short distance from Greenland, so logistically it’s good for us. Additionally, in Iceland you need to be really self-sufficient, and the same can be said for those in Greenland. We don't have as many people or the multitude of services that you would have in other countries which encourages you to think creatively,” he adds.

Consequently, the company has sought to maximise efficiency whilst keeping costs down, yet all the time adding increased value across its operations.

By acquiring a high-grade deposit, less material is needed to be broken down, lowering AEX Gold’s carbon footprint. Everything taken out of the mine from underground will be processed and shipped out to a different processing facility, or processed on site adhering to the current environmental guidelines. Historically, electricity has been generated through the use of traditional fossil fuels, something which is steadily changing throughout Greenland.

“We're using oil to put in generators or to power mobile mining equipment which is high cost both in monetary and environmental terms.   Greenland currently has five hydroelectric power plants and they are looking at building more in south Greenland,” says Olafsson.

Seeing huge opportunities, he explains that the use of hydropower and wind power would complement AEX Gold’s operations, not only in its existing exploration activities, but with the implementation of an electric mining fleet with electricity being obtained from local renewable resources.

Providing local opportunities

In the future, it will be essential for Greenland to gain further revenue to unlock opportunities and services for its citizens. This is something Olafsson believes that AEX Gold can help with due to its knowledge of Iceland as it has many similarities to Greenland and has been through a period of comparable change.

“Greenland is in a similar position to Iceland not so long ago. Iceland didn't have a high education rate and wasn’t wealthy compared to other European countries, with economic and cultural activities that were very insular. We are now at the highest level of all parameters in terms of education, wealth per family, etc. and this has stemmed from improving the breadth of schooling and creating opportunities for people to grow and develop outside of the traditional areas of agriculture and fisheries.

“Our aim is that the majority of employees will be Greenlandic, but it will take time. Greenland has a large number of people competing for jobs in the fisheries and tourist centres. It is important that Greenlanders are able to access programmes that will allow them to consider other career options. In Iceland we are importing a lot of people to work in different industries in our country because we don't have enough people. This might be the case for Greenlanders as well if the anticipated growth of the Mining Sector materialises but we want to ensure that, where possible, we use local people first before looking elsewhere.

“The Greenlandic Government provides good support for those who seek education.  There are an increasing number of Greenlandic students attending Danish Universities so that now, for example, we are seeing well qualified Greenlandic geologists available for employment.  There has been a Mining School at Sisimiut for the last 10 years which provides local qualified labour who can take advantage of opportunities in the Mining sector.  You need skilled labour and as we own a mine that was in production for 10 years previously, there is a fair bit of local knowledge that we have been able to use during our exploration work and which we are keen to utilise going forward,” he says.

“We are creating revenue for local communities, creating highly skilled jobs, and are providing benefits where local communities can live better lives and grow as individuals. We need to create opportunities for young people.”

Additionally, by working with local businesses as well as those who have been operating in Greenland for some time, AEX has made a conscious effort to hire companies which can support its growth. AEX have therefore acquired a longstanding relationship with Cartwright Drilling, due to the company’s extensive experience in Greenland and subsequent knowledge of the island’s government systems, processes and practices.

Planning to mine high-grade resources using significant infrastructure already in place, AEX Gold holds extensive licences managed by an experienced team. Previous operations produced between 50,000 to 100,000 ounces a year at 15.4 grams/ton produced and this has provided a benchmark for the company, who will utilise this cash flow to explore the wider region in the long-term.

“We have a five-year plan where we want to get into production at Nalunaq and use the cash generated to fund exploration in the wider district.   We envisage investing a significant amount in exploration assets to provide a portfolio of different deposits that we can bring into production. We are creating a company that has a long-term mission in Greenland to build up local know how to support our aim of ramping up to very profitable production across a number of projects,” notes Olafsson.

“It will create a dramatic effect on the local community and hopefully be a springboard for unlocking much larger potential in Greenland. There are plenty of deposits that have been found, but you have to be able to develop them. You can only do that that with support and cooperation from the local people who believe in your vision.”

Why AEX consider Greenland a favorable mining location?

favorable legal framework
robust infrastructure

AEX Gold has exploration licenses in South Greenland, covering an area of 690 square kilometers, and the company aims to use hydropower and wind power for its operations.

The Greenlandic Government provides support for education and local employment, which could help to mitigate the social and environmental impacts of mining activities.

The estimated value of Greenland's rare earth minerals is not publicly available, but the country's significant deposits and growing demand for these minerals make it an important player in the global market.

The ease of extraction is a significant challenge, with equipment costs for separating rare earths from rocks currently estimated at $40 million.

How much will it cost to build a facility to separate and extract rare earth minerals?

Despite these challenges, the potential rewards of extracting Greenland's rare earth minerals make it an attractive opportunity for companies and countries seeking to secure a stable supply of these critical minerals.

China's interest in Greenland's iron ore and rare earth minerals is likely to continue, given the country's significant deposits and strategic location.

What countries are invested in Greenland Minerals corp?

The development of rare earth mining in Greenland is expected to have significant economic and environmental implications, and the government will need to carefully balance the benefits of mining with the need to protect the country's unique and fragile environment.

Overall, Greenland's rare earth minerals represent a significant opportunity for companies and countries seeking to secure a stable supply of these critical minerals, but the challenges of extraction and the need to protect the environment must be carefully considered.
