Mount Isa

Mount Isa ( EYE-zə) is a city in the Gulf Country region of Queensland, Australia. It came into existence because of the vast mineral deposits found in the area. Mount Isa Mines (MIM) is one of the most productive mines in world history, based on combined production of lead, silver, copper and zinc. Before European contact, the Mount Isa region was part of an expansive trade network spanning the entire Lake Eyre Basin and beyond. In particular, it was a valued source of stone for stone tools such as hand axes. In the 2021 census, the town of Mount Isa had a population of 18,317 people, making Mount Isa the administrative, commercial and industrial centre for the state's vast north-western region. Although situated in an arid area, the artificial Lake Moondarra 19 kilometres (12 mi) north of the city on the Leichhardt River provides both drinking water and an area for watersports, birdwatching and recreation. Locals often refer to Mount Isa as "The Isa".
