Scientists have announced the discovery of the world’s largest iron deposit, located in Western Australia. This vast deposit is estimated to contain around 55 billion metric tons of iron ore, a staggering resource valued at approximately $5.75 billion. The find challenges previous assumptions about the planet’s iron resources and is expected to lead to significant shifts in the understanding of ore formation and geological processes.
Dr. Liman Courtney-Davis, a geologist from Curtin University, described the discovery as a breakthrough that could prompt a re-examination of textbooks. The value of this deposit far exceeds initial estimates, highlighting its immense economic potential. At an average price of $105 per metric ton, the deposit is seen as one of the richest in the world, cementing Western Australia’s role as a global mining hub.
The discovery has also prompted experts to reconsider the timeline of iron ore formation. Previously believed to have formed 2.22 billion years ago, isotopic analyses of uranium and lead now suggest that these minerals emerged around 1.4 billion years ago. This new insight challenges existing theories on ore development and provides fresh connections to the movement of supercontinents, helping to reshape the understanding of ancient geological events.
The scale of the find has caught the attention of mining companies and exploration teams, as it opens the door to new possibilities for locating similar iron deposits. The study’s use of isotopic dating and chemical analysis techniques offers a clearer picture of the iron’s journey from an initial concentration of 30% to a remarkable 60% in purity. However, the process behind this transformation remains unclear, leaving room for further research and discovery.
