• 09 July 2026The 400-Million-Year-Old Volcanic Arcs That Built a Continent's EdgeThe Lachlan Fold Belt is the largest accretionary orogen on Earth, a 400-million-year-old jumble of volcanic arcs and seafloor sediments that built the eastern third of Australia.
• 27 June 2026The 2.7-Billion-Year-Old Fissure That Still Bleeds GoldHow 2.7-billion-year-old volcanic fissures in Western Australia's Yilgarn Craton created the Golden Mile—the richest square mile of gold on Earth.
• 25 June 2026The 1.7-Billion-Year-Old Lava That Froze a Lake of GoldHow 1.7-billion-year-old volcanic eruptions in Western Australia's Duketon greenstone belt created a gold deposit where metal concentrated in a caldera lake, preserved by ancient weathering
• 20 June 2026The Lava That Froze a 260-Million-Year-Old River of Gold: New South Wales' Hill End GoldfieldHow a 260-million-year-old volcanic event in New South Wales' Hill End goldfield created a gold deposit so rich—and so strange—that it formed in a river of molten lava, not in the surrounding rock.
• 19 June 2026The Lava That Built a 270-Million-Year-Old Reef of Gold: Queensland's Charters TowersHow 270-million-year-old volcanic vents in Queensland's Charters Towers created a gold reef that yielded over 7 million ounces—a mineral system driven by boiling seawater, not magma.
• 19 June 2026The Mud That Turned to Gold Under a 400-Million-Year-Old Volcano: Queensland's Mount Morgan DepositHow volcanic heat and acidic fluids transformed a Devonian mud volcano in central Queensland into one of the world's richest gold-copper deposits—a mineral system that still puzzles geologists.
• 17 June 2026The Ice That Ground a Continent into Gold Dust: Western Australia's Yilgarn PaleoplacersHow 2.7-billion-year-old river systems in Western Australia's Yilgarn Craton concentrated gold into paleoplacer deposits, later buried beneath ancient glacial till and preserved as a record of Earth's
• 24 May 2026The Magma That Bled Gold: Victoria's Deep Leads and the Birth of the Golden TriangleHow 400-million-year-old quartz reefs in Victoria's Bendigo Zone, buried by younger basalt flows, created one of Earth's richest goldfields and an invisible landscape beneath the plains.
• 21 May 2026The Lava That Bled Gold: Queensland's Mount Morgan CalderaHow a 270-million-year-old volcanic caldera in central Queensland concentrated gold and copper into one of Australia's richest ore deposits, a single crater that yielded 260 tonnes of gold.
• 20 May 2026The Magma That Spawned a Goldfield: Victoria's Stawell ZoneHow 450-million-year-old volcanic rocks and deep-crustal faults in western Victoria generated one of Australia's richest gold deposits, where quartz veins still yield nuggets today.
• 18 May 2026The Lava That Became Australia's Largest Gold Mine: Kalgoorlie's Golden MileHow 2.7-billion-year-old volcanic eruptions and ancient fault systems concentrated gold into Western Australia's Golden Mile, one of the richest gold deposits on Earth.
• 18 May 2026The Volcano That Gave Birth to Gold: Victoria's Mount Baw BawHow 380-million-year-old Devonian volcanic activity in eastern Victoria created a unique gold system where magma, limestone, and fault lines conspired to concentrate gold into rich quartz veins.
• 16 May 2026The Gold That Rode a River: Victoria's Deep LeadsBeneath Victoria's basalt plains, ancient river channels buried by lava flows preserve some of the richest alluvial gold deposits ever found.
• 09 May 2026The Gold That Walked: The Witwatersrand Clues of the PilbaraIn Western Australia's Pilbara, 3.4-billion-year-old conglomerates preserve the earliest known placer gold deposits—river sediments that predate all life on land.
• 09 May 2026The Gold That Rained From Space: The Witwatersrand Conglomerates and the Bendigo ConnectionHow the Witwatersrand-style gold deposits of Western Australia's Yilgarn Craton preserve a 2.7-billion-year record of ancient rivers, meteorite bombardment, and the richest gold province on Earth.
