The Mt Rawdon open pit gold operation is located 75km south-west of Bundaberg, Queensland and is surrounded by the traditional lands of the Port Curtis Coral Coast People. Our local communities are Mt Perry, Gin Gin, Biggenden and Gayndah. Evolution has owned and operated Mt Rawdon since November 2011.
Mt Rawdon has produced over 50 tonnes of gold since the mine began operating and is a reliable contributor to our group production over the last eight years. With a mine life of another seven years and a motivated, innovative workforce the team is ensuring that Mt Rawdon remains a low cost, high margin asset for Evolution.
Total FY19 gold production of 94,647oz was just below the bottom end of the 95,000 – 105,000oz guidance range. AISC of A$1,233/oz was above the top end of the A$1,000 – A$1,050/oz guidance. The poor FY19 production and costs was predominantly driven by reduced access to higher grade ore in the open pit. Full year mine operating cash flow was A$60.0 million. Net mine cash flow was A$31.6 million.
FY20 guidance: 90,000 – 100,000oz at an AISC of A$1,210 – A$1,260/oz
In FY18 Mt Rawdon won the People’s Choice Award at the Queensland Mine Safety Awards for their innovative “Barrel Mate” initiative. The team also designed and built a used tyre protection wall as a bund to protect against rock falls. Improvements were made in blast efficiencies with: improved fragmentation; reduced blast delays; and reduction in downtime for blast evacuations.
