Australia’s Remote Billion-Dollar Gold Mine: The Tanami Gold Mine

Australia’s Remote Billion-Dollar Gold Mine: The Tanami Gold Mine

The Tanami Gold Mine is one of Australia’s most significant and remote gold producers. Located deep in the Northern Territory desert, it has delivered more than twelve million ounces of gold since the 1980s and continues to generate billions in revenue each year. Its unique geology, long mine life and ambitious expansion projects make it a cornerstone of the Northern Territory’s mining industry and one of Newmont’s flagship global assets.

Queensland Was Once Connected To Canada: The Georgetown Inlier

Queensland Was Once Connected To Canada: The Georgetown Inlier

Beneath the quiet town of Georgetown in north Queensland lies a geological secret: a fragment of Canada. Known as the Georgetown Inlier, this ancient block of crust began its life as part of Laurentia, the heart of North America, before drifting away and colliding with Australia 1.6 billion years ago. Its rocks preserve the isotopic fingerprints of Canada’s Wernecke Supergroup, offering a rare glimpse into the assembly of Earth’s early supercontinents.

Australia’s Most Important Mineral Deposit: Mount Weld

Australia’s Most Important Mineral Deposit: Mount Weld

Mount Weld in Western Australia is one of the world’s richest rare earth deposits. Its unique geology and immense strategic value make it Australia’s most important mineral treasure.

One of the Richest Gold Copper Discoveries in Australian History: Ernest Henry

One of the Richest Gold Copper Discoveries in Australian History: Ernest Henry

The Ernest Henry Mine in Queensland is one of Australia’s richest copper-gold discoveries. Hidden beneath barren ground until 1991, this world-class deposit has since produced billions of dollars in copper and gold, shaping both local communities and the nation’s mining legacy.

The Devastating 2025 Afghanistan Earthquake: A Geological Analysis

The Devastating 2025 Afghanistan Earthquake: A Geological Analysis

A magnitude 6.0 earthquake struck eastern Afghanistan late on August 31, 2025, tearing through narrow valleys in Kunar Province and leaving more than 1,400 people dead and over 3,000 injured. Entire villages built of adobe and field stone collapsed within seconds, while rain-loosened slopes gave way in chains of landslides that severed roads and isolated survivors. What turned a moderate-sized quake into a national disaster was not just where it hit, but how the crust moved beneath it.

Australian Pink Salt Versus Himalayan Mountain Salt

Australian Pink Salt Versus Himalayan Mountain Salt

Australia is home to its own remarkable pink salt, harvested each year from the Murray–Darling Basin. While Himalayan salt gets most of the attention, Murray River Salt tells a very different story. Drawn from ancient saline aquifers and crystallised under the hot Australian sun, these delicate pink flakes are not only prized in kitchens for their light texture and balanced flavour, but also play a vital role in tackling salinity across the Murray River system.

The Bizarre Lake That Disappears Overnight: Loughareema

The Bizarre Lake That Disappears Overnight: Loughareema

Loughareema, the vanishing lake of Northern Ireland, is one of nature’s most puzzling spectacles. This shallow basin in County Antrim can transform dramatically within hours. After heavy rains, streams pour into the hollow, filling it with dark, peaty water and creating a striking upland lake. Yet the waters are fleeting. Hidden beneath the lakebed is a natural sinkhole that acts like a giant plug, draining the lake away into subterranean channels that feed the nearby Carey River.

A Colossal Cave System lurking Beneath Australia’s Desert: The Nullarbor Caves

A Colossal Cave System lurking Beneath Australia’s Desert: The Nullarbor Caves

Beneath the flat, treeless expanse of the Nullarbor Plain lies one of Australia’s most astonishing hidden worlds. This vast limestone platform conceals an immense system of caves, tunnels and sinkholes formed over millions of years. From colossal chambers decorated with stalactites to crystal-clear underground lakes, the Nullarbor’s caves reveal a story of ancient seas, extinct megafauna and the remarkable power of water to carve stone.

Why Victoria's New Machete Ban Makes No Sense

Why Victoria's New Machete Ban Makes No Sense

Victoria’s machete ban has been sold as a bold move against knife crime, but in reality it criminalizes ordinary people while doing little to stop violent offenders. From September 1st, 2025, owning or using a machete could land you with a $47,000 fine or two years in prison. The government has spent $13 million on disposal bins to enforce the ban, yet critics argue this is political theatre rather than practical safety.

Why Criminal Gangs Are Killing for Sand: The Sand Mafia

Why Criminal Gangs Are Killing for Sand: The Sand Mafia

Sand may seem like an endless resource, but the truth is far more troubling. The construction industry depends on sharp, angular river sand — not the smooth grains of desert dunes. As global demand surges, this vital resource is being stripped from rivers and coasts faster than nature can replace it. In countries like India, Morocco, and Kenya, this shortage has fueled a violent black market, controlled by cartels known as sand mafias. These groups will stop at nothing — intimidation, corruption, and even murder — to secure control over sand supplies. What looks like a humble grain has become the foundation of a billion-dollar criminal empire.

A 500 Metre Tall Mega Tsunami Just Struck Alaska - New Photos Released

A 500 Metre Tall Mega Tsunami Just Struck Alaska - New Photos Released

On August 10, 2025, a colossal landslide in Tracy Arm fjord unleashed a half-kilometer high mega-tsunami. Newly released photos reveal the scale of destruction and the science behind one of the largest landslide-generated waves in modern history.

Largest Earthquake In 50 Years Hits Queensland: Here’s What Happened

Largest Earthquake In 50 Years Hits Queensland: Here’s What Happened

Queensland has been shaken by its strongest earthquake in half a century. The magnitude 5.6 tremor struck near Kilkivan, west of Gympie, and was felt across Brisbane, Bundaberg, the Gold Coast and even into northern New South Wales. It is a rare reminder that even Australia’s most stable state is not immune to powerful geological forces.
