• 10 July 2026The 2.5-Billion-Year-Old Volcano That Still Holds 3,000 Tonnes of CopperIn South Australia's Olympic Dam, a 2.5-billion-year-old volcanic-hydrothermal system created the largest uranium deposit on Earth and a copper resource so vast it reshaped an industry.
• 05 July 2026The 1.6-Billion-Year-Old Seafloor That Was Turned Inside OutHow 1.6-billion-year-old volcanic islands on South Australia's Yorke Peninsula were folded, thrust upward, and turned into a copper district that built a colony.
• 27 June 2026The 3.5-Billion-Year-Old Spring That Stole the Ocean's CopperHow 3.5-billion-year-old volcanic hot springs in Western Australia's Pilbara Craton created the world's oldest known copper deposit—metal concentrated not by magma, but by Archaean seawater boiling th
• 26 June 2026The 640-Million-Year-Old Volcano That Melted a Mountain of CopperHow a 640-million-year-old submarine volcanic arc in western Tasmania became the Mount Lyell copper-gold deposit—born from black smokers, hardened by metamorphism, and exposed by 100 million years of
• 20 June 2026The Copper That Rained from a 1.6-Billion-Year-Old Sky: South Australia's Mount Gunson CopperHow 1.6-billion-year-old sediments in South Australia's Mount Gunson region trapped copper from hydrothermal fluids, creating a deposit where the metal is concentrated in ancient stromatolite reefs.
• 19 June 2026The Copper That Boiled Out of a 1.6-Billion-Year-Old Sea: South Australia's Olympic DamHow a 1.6-billion-year-old volcanic cauldron beneath South Australia's arid plains created the world's largest uranium deposit and one of its richest copper provinces, a mineral system unlike any othe
• 17 June 2026The Ash That Buried a Garden of Giants: Tasmania's Mount Read Volcanic BeltHow 500-million-year-old submarine volcanoes in western Tasmania built a massive deposit of copper, lead, zinc, gold, and silver—one of Earth's richest volcanic-hosted massive sulphide systems.
• 24 May 2026The Ash That Painted a Desert in Gold and Rust: South Australia's Arkaroola Hydrothermal SystemHow 1.6-billion-year-old hydrothermal veins in South Australia's Arkaroola region deposited copper, gold, and uranium, creating a mineralised landscape that still leaks hot water today.
• 21 May 2026The Lava That Bled Copper: South Australia's Olympic DamHow a 1.6-billion-year-old volcanic-hydrothermal system beneath South Australia's Gawler Craton created the world's largest uranium deposit and fourth-largest copper deposit, all hidden under 300 metr
• 18 May 2026The Volcano That Raised a Mountain of Copper: Tasmania's Mount LyellHow 360-million-year-old volcanic activity on Tasmania's west coast created the Mount Lyell copper deposit, where ancient seafloor vents built a mountain of ore later mined for a century.
• 17 May 2026The Volcano That Gave Birth to Australia's Largest Copper Mine: South Australia's Olympic DamHow a 1.6-billion-year-old volcanic caldera in South Australia's Gawler Craton concentrated copper, uranium, gold, and silver into the world's largest known uranium deposit and fourth-largest copper d
