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.
