Mungari (100% Ownership)

The Mungari gold operation is located 600km east of Perth and 20km west of Kalgoorlie in Western Australia on the traditional land of the Maduwongga People. Our local communities are Kalgoorlie and Coolgardie. The operation is a key asset in Evolution’s portfolio and consists of underground mining at Frog’s Leg, open pit mining at White Foil and a strategically located 1.6Mtpa process plant.

Safety improved at Mungari with a significant reduction in Significant Safety Occurrence Frequency (SSOF) over the year from 6.0 to 2.4 and TRIF from 13.3 to 9.7. The operational performance also improved, highlighted by milling costs reducing by A$2/t processed against budget. Total gold production for FY18 of 118,498oz was slightly below guidance of 120,000 – 130,000oz which resulted in FY18 AISC of A$1,181/oz being above the guidance range of A$990 – A$1,050/oz. Full year net mine cash flow was A$23.7 million.

Mungari’s performance is expected to improve in FY19, built on the completion of the White Foil Stage 3 cutback and increased availability of high-grade ore feed from Frog’s Leg underground.

The operation has a major footprint in the world-class Kalgoorlie gold district with opportunities for highgrade discoveries to expand production and lower costs. The operation currently has a 10 year mine plan and an aspiration to lift annual production up to a sustainable 150,000 ounce profile. Opportunities currently being investigated to support this production rate include:
  • Un-constraining the crushing and leach circuit through data analysis to increase plant throughput to 1.9 – 2.0Mtpa
  • Ore sorting technology to deliver the highest grade to the processing plant
  • High-grade discoveries from an extensive regional
  • exploration program
  • Heap leach options
  • Data analysis of seismicity to identify potential mineralisation
