The company will use the sale proceeds to reduce its debt by $3bn.
Barrick Gold co-president Kelvin Dushnisky said: "The sale of Cowal is consistent with the strategy we have outlined to create long-term value for our owners, and will make a significant contribution to our debt reduction target while further focusing the geographic footprint of our portfolio."

Claimed to be one of Australia's attractive gold assets, the Cowal gold mine is a long-life operation and will improve the quality of Evolution's asset portfolio.
Evolution Mining executive chairman Jake Klein said: "The addition of Cowal to our asset portfolio is an exciting step forward for Evolution and provides us with a cornerstone asset of the highest quality.
"We welcome our new Cowal employees and look forward to building a long and successful relationship with the communities of the Bland, Lachlan and Forbes Shire."
