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 is now a core asset and one of the highest-grade open pit gold mines in the world.
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
Total FY20 gold production of 58,962 ounces at an AISC of
$1,453/oz did not meet production or cost guidance.
Mt. Carlton operation has ISO 14001-2015 Certificate for Mining, Ore Processing Operations, and Support Services for Gold production.
