Kalgoorlie Super Pit

The Kalgoorlie Super Pit, run by Kalgoorlie Consolidated Gold Mines Pty Ltd (KCGM), is the largest open-cut gold mine & 3rd largest open-cut mine in the world. KCGM was created by Alan Bond in the 1989 when he consolidated a heap of mining leases to allow the open cut to begin.

We took the 2.5 hour Super Pit tour with Kalgoorlie Tours & Charters which was pretty good. We learnt a lot about the super pit and the massive scope of operations required to extract and process gold from the mine. The Super Pit…

  • is 3.9 km long and 1.6 km at its widest point
  • covers 35,000 hectares and is approx 600 metres deep
  • produces around 700,000 ounces of gold per year from around 15 million tonnes of extracted rock
  • the big dredges and trucks last about 7 years and are then replaced
  • they use 5 to 6 million litres of diesel fuel per month and store 700,000 litres onsite
  • KCGM expected gold processing to finish at the mine in 2021, however it now plans to extend ore processing until 2029
