Mt Carlton (100% Ownership)

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 example of thinking differently to unlock a previously uneconomic deposit. 

The operation was developed by Evolution and commissioned in 2013. It has fully repaid all its capital and has generated an average return of 19% per annum. 

The operation underwent some resource challenges during the year where the main hydrothermal breccia zone, which made up the bulk of the mineralisation in the V2 pit, tapered to a series of narrower, high-grade feeder structures at shallower depths than anticipated. This resulted in poor reconciliation between the Ore Reserve and the grade control models.

Mt Carlton successfully completed the initial underground mine development and plant upgrades with the underground operation commencing full production during March 2020, ahead of schedule and under project costs,
which was a significant milestone for the asset. This work, along with a strong focus on operating discipline, enabled the operation to deliver a record mill throughput in FY20 of 894kt.

Total FY20 gold production was 58,962 ounces at an AISC of $1,453/oz. 

Mt. Carlton operation has ISO 14001-2015 Certificate for Mining, Ore Processing Operations, and Support Services for Gold production.
