Evolution gained a foothold in Ernest Henry in 2016 when it struck a A$880 million deal with Glencore to acquire 100% of the operation's gold production and 30% of its copper production over its defined reserve life of 11-years as well as 49% of production from new exploration from 2027 onwards.
But Evolution will now assume full ownership and operational control of the copper-gold mine and will enter into a copper concentrate offtake agreement and separate ore tolling agreement with Glencore. The product will continue to be treated at Glencore's Mt Isa smelter and Townsville refinery.
The transaction is expected to close in early January 2022.
The deal does not increase Evolution's revenues from current gold production, but will increase its exposure to silver and copper, and increase its stake in further exploration at the resource.
Evolution's 2022 production guidance is 670,000 - 725,000 ounces of gold at an all-in sustain cost of A$1,135-1,195 per ounce.
