"As always, we will continually adapt our business to suit changing market conditions," Schack said. "This may include further restructuring and/or reductions in the future."
The move affects several groups of support function employees, including administrative, human resources and purchasing workers. The company has 4,500 employees in Nevada which makes up the bulk of its North American operations and 140 employees in Salt Lake City.
Affected employees have been given time to review the severance offers and to make their decisions. The offers include a payment based on years of service and base pay, and limited continuation of some benefits.
The reduction follows a review of the company's organizational structure that was prompted by the change in business conditions.
"Our North American operations, most of which are in Nevada, [make up] the most valuable and productive of Barrick's four regional business units and we intend to keep it that way," Schack said. "To do so, we must cut costs and become a more efficient business."
Shares of Barrick and almost every major gold miner have hit new annual lows this year. Gold prices in recent weeks plunged 7 percent, settling jut above $1,200 an ounce on Wednesday, to levels not seen since September 2010.
Barrick shares are trading in the $17 range, meaning the company's market value is less than half of what it was a year ago.
Another leading gold miner, Newmont Mining Co., hinted it may lay off some employees in Nevada after announcing plans last week to cut its workforce in Colorado by 33 percent.
