Our Mt Carlton operation is located 150km south of Townsville, Queensland, on the traditional lands of the Birriah People. Our local communities are Gumlu, Home Hill, Bowen and Townsville. At Mt Carlton, Evolution developed the expertise to commercialise a refractory, non-oxidised, high-sulphidation epithermal deposit which is a great credit to our people.
The operation was developed by Evolution and commissioned in 2013. It is now a highly successful core asset and is one of the highest-grade open pit gold mines in the world with an innovative team culture driving this impressive performance. The operation has a current mine life out to 2025 and further mine life extensions are likely.
Ore is sourced from the V2 gold-copper-silver deposit which is processed on site to produce a concentrate and shipped to China for smelting. The process plant has a current capacity of 840ktpa. Approximately 10 – 15% of gold feed is recovered through a gravity circuit prior to the flotation circuit to produce doré gold bars which are sold to the ABC Refinery in Sydney. The gravity circuit was installed in 2017 and has lifted recoveries from 88% to 90 – 91%.
Mt Carlton produced more than 100koz of gold for the fourth year in a row with FY19 production of 106,646oz. This exceeded the top end of the 95,000 – 105,000oz guidance range. AISC of A$737/oz was slightly above the top end of of A$620 – A$720/oz guidance. Full year mine operating cash flow was A$120.2 million. Net mine cash flow was A$84.6 million.
FY20 guidance: 95,000 – 105,000oz at an AISC of A$800 – A$850/oz.
Mt. Carlton operation has ISO 14001-2015 Certificate for Mining, Ore Processing Operations, and Support Services for Gold production.
Focus at Mt Carlton is on progressing Stage 3 with underground development due to commence in the September quarter 2019.
