Northern Vertex Mining Corp. has completed its 6.9-mile electrical powerline project. The system was energized on September 9 and the diesel generator bank shut down on September 10. The Moss gold and silver mine in Arizona is now linked to the Mojave Electric power grid, and the company said it is now beginning to realize numerous benefits, which include reducing electrical costs from approximately $0.31 per kilowatt-hour (kwh) to a grid system cost $0.08/kwh.

The move also eliminated the operational and maintenance cost of operating the diesel gensets, which attribute a savings of $15 million to $20 million over the life of mine. All of this translates into a $50/oz all-in sustaining cost savings, the company said. 

“The completion of the powerline and successful connection to the electrical grid further reduces our operating costs, improves reliability, and is a demonstration of Northern Vertex’s commitment to sustainability by reducing our carbon footprint,” Northern Vertex President and CEO Ken Berry said. “Furthermore, the company will continue with several cost savings initiatives that 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 ongoing exploration success of recent drilling to establish the Moss mine as a highly profitable, long-life operation.”
