Mount Isa Lead, Zinc and Silver Mine Mining Technology
By the 1960s, Mount Isa was the hub of a lead, zinc, silver and copper supply network, including smelting, refining and recycling facilities in Europe. In 1970, MIM Holdings succeeded Mount Isa Mines but, while diversifying in the 1970s and 1980s, management seemingly neglected Mount Isa. Revitalisation started in the late 1980s.
