Mount Isa 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 single mines in world history,
based on combined production of lead, silver,
copper and zinc.

With an estimated population of 22,517 as at June
2015, Mount Isa is 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".
