MCEWEN MINING ANNOUNCES SIGNIFICANT PERMITTING MILESTONE FOR GOLD BAR

McEwen Mining Inc. has achieved a critical step in the permitting process for its Gold Bar project in Nevada in line with the company's plans to begin mine development in the fourth quarter of this year.

On Oct. 6, 2017, the Environmental Protection Agency (EPA) published a notice of availability of the final environmental impact statement (EIS) in the federal register. Following a regulated review period, a signed record of decision will be published, signifying the completion of the National Environmental Policy Act (NEPA) process. The record of decision is expected in early November this year and development of Gold Bar is planned to begin upon receipt.

"This is a key permit milestone for our Gold Bar project, that once constructed is projected to produce 65,000 ounces of gold per year starting in 2019. This achievement was a team effort that required the co-ordination and commitment from our staff, the BLM, Eureka County Board of Commissioners and many other co-operating agencies," said Rob McEwen, chairman and chief owner.
