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 has a current mine life out to 2025.
The development of an underground mine from within the open pit was approved in FY19 and its development will be the next significant milestone for the operation.
Mt Carlton produced more than 100koz of gold for the third year in a row with FY19 production of 106,646 ounces. This was an impressive achievement considering the operation had to manage through a significant rain event which shut operations and restricted site access for over 30 days during
the third quarter. This was a very concerning period with the safety of our Mt Carlton people front of mind.
Despite these challenges, our team performed admirably and Mt Carlton exceeded the top end of the 95,000 – 105,000oz guidance range. An AISC of A$737/oz was slightly above the top end of the A$670 – A$720/oz guidance. Full year net mine cash flow was A$84.6 million.
During the year we achieved a world first by trialling an online gold analysis (OLGA) technology developed by the CSIRO. This gives the processing team the ability to adjust processing parameters effectively, in real time, with the
effect of reducing losses to tailings.
Mt Carlton is extremely proud to have produced the gold for the 2019 Lexus Melbourne Cup which brought the Melbourne Cup Tour to the local community in August 2019.
Mt. Carlton operation has ISO 14001-2015 Certificate for Mining, Ore Processing Operations, and Support Services for Gold production.
