The diesel generator bank that had powered the mine was shut down on September 10, the day after the new system was energised.
The Moss mine is now linked to the Mojave Electric power grid. Since coming online, Northern said it has reduced its electricity costs and also boosted its operation and maintenance savings to C$15 to C$20 million over the mine's lifespan.
The miner also noted that it will continue to realise the environmental advantages of transitioning to grid power from diesel generators.
"The company will continue with several cost savings initiatives which include: the successful transition to McCoy and Sons as our dedicated mining contractor; the completion of the intermediate leach system to accelerate gold recoveries; and our on-going exploration success of recent drilling to establish the Moss Mine as a highly profitable, long-life operation," president and CEO Kenneth Berry said.
Northern Vertex Mining owns 100% of the Moss mine in northwestern Arizona.
