Mt. Morgan is located in Queensland, Australia and was the largest gold mine in the world at its peak in the early 1900s. Over its lifespan, the mine yielded approximately 262 metric tons of gold, 37 metric tons of silver and 387,000 metric tons of copper.
As with many older mining projects, the legacy of Mt. Morgan is a large hole in the ground, waste and tailings stockpiles that produce contaminated water and a town with high unemployment. Today, Mt. Morgan is a tourist attraction demonstrating the scale of environmental damage unwittingly caused by the old mining companies. This sole benefit must be weighed against the high ongoing cost to the government in treating the contaminated water discharging to the Dee River.
