The Forgotten Beach Gold Rush in New South Wales

The Forgotten Beach Gold Rush in New South Wales

Australia is known for its legendary goldfields, but few people realise New South Wales once hosted a genuine beach gold rush. Hidden behind the dunes near Evans Head, a fossilised ancient shoreline produced thousands of ounces of ultra-fine gold during the 1890s. This rare coastal placer formed when heavy minerals and gold from the New England highlands were reworked by shifting sea levels and storm-driven waves into a narrow, cemented strandline now buried beneath metres of sand. Forgotten for more than a century, this lost auriferous beach reveals one of the most unusual geological and mining stories in Australian history.

The Massive Australian Cave System You Never Hear About

The Massive Australian Cave System You Never Hear About

Hidden beneath the remote landscapes of the Northern Territory lies Bullita Cave, Australia’s longest and least-known cave system. This enormous 123-kilometre underground labyrinth stretches through ancient Proterozoic dolostone in the Judbarra and Gregory Karst region. Its maze-like passages, shallow depth and astonishing density make it one of the most unusual cave networks on Earth. Bullita formed through the combined power of monsoonal flooding, rapid vertical infiltration and the erosion of a critical shale layer, producing a sprawling subterranean world that most people have never even heard of. This article explores the geology, hydrology and evolutionary history of Australia’s largest cave system and reveals why this hidden underworld is unlike anything else in the country.

The Only Place on Earth You Can Find This Rock

The Only Place on Earth You Can Find This Rock

Hidden in the remote Kennedy Range region of Western Australia lies one of Earth’s rarest gemstone materials: Mookaite. This striking, multicoloured silicified radiolarite formed on the floor of an ancient Cretaceous sea and occurs only in a tiny area near Mooka Creek. In this article, we explore how microscopic marine fossils were transformed into one of Australia’s most distinctive gemstones, why it formed in only one locality, and what makes Mookaite a geological outlier unlike anything found anywhere else on the planet.

World Shocked As “Extinct” Volcano Reawakens: Hayli Gubbi

World Shocked As “Extinct” Volcano Reawakens: Hayli Gubbi

A volcano in Ethiopia has erupted for the first time in twelve thousand years, sending shockwaves through the scientific community and drawing global attention to one of the most active tectonic regions on Earth. This rare eruption of Hayli Gubbi in the Afar Depression reveals the immense geological forces tearing Africa apart and offers a dramatic glimpse into the formation of a future ocean basin. Explore how a supposedly extinct volcano reawakened, why it erupted so violently and what this event means for the East African Rift System.

Everything We Knew About The Giant's Causeway Was WRONG

Everything We Knew About The Giant's Causeway Was WRONG

For decades, the Giant’s Causeway was explained as a simple case of lava cooling in a river-carved valley — but new geological evidence rewrites that story entirely. Beneath the iconic basalt columns lies a hidden record of magma chamber collapse, rapid subsidence, and a volcanic event far more dramatic than the traditional explanation ever suggested. This article breaks down the new science behind the Causeway’s formation, the clues geologists uncovered in the laterite layer, and why everything we thought we knew about this landscape has now changed.

One of The Strangest Places on Earth: The Chocolate Hills in The Philippines

One of The Strangest Places on Earth: The Chocolate Hills in The Philippines

The Chocolate Hills of Bohol are one of the strangest and most visually striking geological landscapes on Earth. Beneath their calm, symmetrical beauty lies the story of an ancient coral reef uplifted from the sea and sculpted into nearly two thousand perfect domes by millions of years of tropical rainfall, chemical weathering and karstification. This blog post explores the real science behind the Chocolate Hills, their Pliocene limestone origins, their hidden cave systems and underground rivers, and the delicate balance that keeps this rare tropical karst environment alive.

The Huge Super Volcano in Victoria Australia

The Huge Super Volcano in Victoria Australia

Hidden beneath the tranquil forests of Victoria lies one of Australia’s most extraordinary geological secrets: the Cerberean supervolcano. This massive 27-kilometre-wide caldera, preserved in the high country near Marysville and Lake Mountain, marks the site of one of the largest explosive eruptions in Australia’s deep-time history. With nearly nine hundred cubic kilometres of ignimbrite packed inside the caldera, the Cerberean eruption rivals the great supervolcanoes of the world and showcases the incredible power of ancient Australian volcanism. This blog post explores how the eruption unfolded, how the enormous magma chamber formed beneath the Selwyn Block, and how the collision of the VanDieland microcontinent set the stage for one of the most violent geological events ever recorded on the continent.

The Unsolved Mystery of The Gold & Silver Rich Hera Deposit

The Unsolved Mystery of The Gold & Silver Rich Hera Deposit

Hidden beneath the quiet landscape of central New South Wales lies one of Australia’s most mysterious and valuable mineral discoveries: the Hera gold and silver deposit. Long believed to be a region dominated by traditional Cobar-style ore systems, the Cobar Basin was turned on its head when Hera revealed extreme heat signatures, exotic skarn minerals and a suspected but still undiscovered magmatic heat source. This extraordinary deposit produced hundreds of thousands of ounces of gold and silver while exposing a geological puzzle that continues to challenge experts. In this deep-dive exploration, we unravel the formation of the Hera skarn, the billion-dollar metals it hosted, and the unanswered questions that make it one of Australia’s most compelling geological mysteries.

The Secret Every Gold Prospector Needs To Know

The Secret Every Gold Prospector Needs To Know

Gold prospecting has long been dominated by the belief that quartz veins are the primary source of gold, but this outdated idea keeps countless prospectors blind to the richest auriferous systems on Earth. The truth is that some of the most productive gold deposits have little to no quartz at all. Weathered sulfide lodes, ironstone gossans, silicified zones, fault gouge, carbonaceous slates, volcanic alteration and deep-weathered regolith can all shed visible gold, fine gold and coarse nuggets into the landscape without leaving a single classic quartz vein behind. In this article, we explore these hidden geological gold sources in detail and show how understanding them can completely transform your prospecting success. If you want to find the gold everyone else walks over, this is the knowledge that makes the difference.

The Supervolcano in Central Australia That Rewrote Geology

The Supervolcano in Central Australia That Rewrote Geology

Deep beneath the deserts of central Australia lies a billion-year-old supervolcano that changed everything we know about how Earth works. The Talbot Sub-basin in the Musgrave Province produced colossal eruptions that rivaled Yellowstone and Toba — but unlike them, it wasn’t powered by a deep mantle plume. This was a supervolcano born from crustal heat, rewriting the rules of geology and proving that continents themselves can generate planet-shaping eruptions.

Inside The Largest Zircon Mine in the World

Inside The Largest Zircon Mine in the World

Beneath the South Australian outback lies one of the world’s richest hidden resources — the Jacinth–Ambrosia zircon mine. Valued at over A$15 billion, this world-class mineral sands deposit produces a quarter of global zircon supply. Formed on Eocene beaches 40 million years ago, these ancient dunes conceal a geological and economic marvel. Learn how billion-year-old zircons from the Musgrave Province ended up buried in the Eucla Basin, how Iluka Resources turned that discovery into a global powerhouse, and why this remote desert is now home to the planet’s most valuable zircon deposit.
