This Mine Shouldn’t Exist… But It’s Worth Billions: The Costerfield Mine
Discover the Costerfield Mine in Victoria, Australia—a high-grade underground gold antimony deposit worth billions. Learn how narrow quartz-stibnite veins formed and why antimony is now a critical mineral in global supply chains.
The Devastating 100 Metre Tall MEGA TSUNAMI of 1888
In 1888, Ritter Island collapsed into the ocean, triggering a devastating mega tsunami. This video explores how volcanic landslides create tsunamis, the science behind extreme wave heights, and why this forgotten disaster may have produced waves over 100 metres tall. Learn how landslide-generated tsunamis differ from earthquake tsunamis, why the ocean receded before impact, and what this event reveals about future coastal hazards.
One of the World’s Most Critical (Yet Overlooked) Resources: Bauxite
Bauxite is one of the world’s most critical yet overlooked resources, forming the foundation of global aluminium production. This video explores the massive Weipa bauxite deposit in Queensland, Australia, and explains how lateritic weathering creates aluminium-rich ore over millions of years. Discover how pisolitic bauxite forms, why the deposit is still evolving today, and how this quiet resource powers modern infrastructure, renewable energy, and global industry.
One of The Strangest Lakes on Earth: Lake Natron
Discover the shocking truth about Lake Natron, the lake that appears to turn animals to stone. This video explains the real science behind its extreme alkalinity, how it preserves dead animals, and why flamingos thrive in one of the harshest environments on Earth.
They Just Found BILLIONS in Gold & Silver in New Zealand
A massive high-grade gold and silver discovery in New Zealand is revealing a rare, free-milling epithermal system worth billions. This article breaks down how gold and electrum formed in volcanic rocks, why the grades are so high, and what makes this deposit one of the most exciting modern gold discoveries.
The Recent South Australia Earthquake Explained
A recent earthquake in South Australia has revealed something extraordinary beneath the surface. This video explores how a magnitude 5.5 earthquake in the APY Lands is linked to ancient faults formed over 500 million years ago during the Petermann Orogeny. Learn how intraplate earthquakes occur in Australia, why seismic activity can happen far from plate boundaries, and how deep crustal structures still control movement today.
An Entire Town Built Beneath the Australian Desert
Discover the incredible geology behind Coober Pedy, the world’s largest opal field and one of the strangest towns on Earth. In this episode, we uncover how an ancient inland sea within the Great Artesian Basin created the perfect conditions for opal formation, and why this barren desert is filled with hidden treasure. Learn how silica-rich groundwater formed opal over millions of years, why deposits are so unpredictable, and how this unique geology led to one of Australia’s most fascinating mining towns.
The Most Extreme Place on Earth: A True Geological Oddity
Discover why the Danakil Depression in Ethiopia is one of the most extreme and geologically insane places on Earth. Located in the Afar region, this alien landscape sits along an active continental rift where the African Plate is tearing apart. In this video, we explore mantle plumes, tectonic plate movement, volcanic activity, hydrothermal systems, and how this region represents the early stages of ocean formation. From the acid pools of Dallol to the lava lake at Erta Ale, this is Earth in its rawest and most violent state.
A Newly Discovered Massive Gold, Silver, Copper Deposit
Discover one of the biggest gold discoveries in 30 years at Filo del Sol. Learn how this massive gold, copper and silver deposit formed and why it’s so unique.
A Hidden Buried River Full of Gold in Western Australia
A hidden buried river full of gold in Western Australia—this video explores the Higginsville palaeochannel, a deep lead missed by early miners and only discovered through modern geology. Learn how ancient rivers concentrated gold, how these deposits became buried under tens of metres of sediment, and why they remain some of the most overlooked gold systems in Australia. From formation to discovery and mining, this is a complete breakdown of one of the most fascinating hidden gold deposits in the Yilgarn.
The $30 Billion Discovery Hidden in Australia: The Ranger Uranium Gold Deposit
Discover the $30 billion mining discovery hidden in Northern Australia and uncover the geology behind one of the most unusual mineral deposits on Earth. This video explores how gold and uranium formed together in the Ranger deposit, why it’s so rare, and how it changed Australian mining forever.
