Australia makes £4.5 trillion find that could change entire world’s economy

Australia has made a £4.5 trillion discovery of the world's largest iron deposit in the Hamersley region, significantly impacting the global economy and mining practices. The deposit, estimated at 55 billion metric tonnes with iron concentrations above 60%, could solidify Australia's position as the leading iron ore exporter. New imaging technology revealed the deposit's age to be 1.4 billion years, rather than the previously estimated 2.2 billion years, offering new insights into Earth's crust evolution and ancient geological processes.
