Kalgoorlie Super Pit and the Golden Mile
Deep desert gold mines, giant yellow trucks, historic water pipes, and shining metal bars.
Early Gold Finds and Desert Towns
In June 1893 an Irish prospector named Paddy Hannan found bright gold near Mount Charlotte.
The hard rock below the desert contained rich networks of quartz and gold metal.
People called this rich land the Golden Mile because miners found gold everywhere.
An engineer named C. Y. O'Connor built a long water pipeline from Mundaring to Kalgoorlie.
Early miners dug hundreds of deep holes and wooden shafts to find shiny gold.
Miners built tall stone hotels and wide roads along Hannan Street in the busy town.
The Giant Open Pit and Big Trucks
In 1989 mining leaders joined small underground mines together to dig one giant pit.
Workers call this huge open pit the Super Pit, and it stretches across three kilometers.
The giant canyon goes down more than six hundred meters below the desert ground.
Workers drill deep holes and blast hard rocks every week to break the stone.
Large power shovels load heavy yellow Caterpillar haul trucks with two hundred tonnes of rock.
Modern radar scanners check the steep rock walls continuously so rocks do not fall down.
Crushing Rocks and Melting Pure Gold
Large rock crushers and rolling ball mills grind heavy boulders into fine powder.
Water tanks and bubble machines separate gold minerals from dark waste rock.
Workers use roasting ovens to liberate microscopic gold from crushed rock.
Special tanks use liquid and black carbon to collect the floating gold metal.
Hot melting ovens heat the recovered gold at over one thousand degrees into shiny dore bars.
The Super Pit makes hundreds of thousands of ounces of gold every single year.
Jobs, Deep Tunnels, and Sacred Heritage
Gold mining gives thousands of important jobs to families living in the desert towns.
Australia is one of the top gold producers in the entire modern world.
Miners are now digging new underground tunnels deep under the bottom of the pit.
Aboriginal groups like the Maduwongga and Kaprun have cared for this red earth for generations.
Heritage programs protect historic wooden headframes and old landmark buildings in town.
Planting native green bushes over old dirt heaps helps the dry desert land heal.
