Broken Hill’s Lost Mineral Treasure Found | Sydney News

A mining breakthrough in Broken Hill unlocks a 40-year-old mineral deposit buried beneath the city streets, hidden behind an impossible geological barrier. Engineers cracked the code with a smart drilling technique—first drilling wide, then casing it to create a stable path through the pulverized rock. Early results show the deposit is five times thicker and zinc purity nearly double expectations, hinting at a potential 20 million tonnes of high-value ore. This could secure long-term operations for the region, though extracting it remains a massive engineering challenge ahead.
