On September 1, Northern Vertex Mining Corp., the newest gold producer in the U.S., declared commercial production at the Moss Gold mine. Located in northwest Arizona, the Moss mine is an open-pit, heap-leach mine using excavators and articulated haulers to move ore to a crushing installation, which recently delivered a record rate of 13,000 metric tons per day (mt/d). The feasibility study envisioned 5,000 mt/d. With the improved production results, the company said it expects the mine to produce 36,000 ounces (oz) to 40,000 oz gold equivalent in fiscal year 2019 and 59,000 oz to 65,000 oz gold equivalent in fiscal year 2020.

“Commercial production is a significant milestone for our team of approximately 100 men and women operating the Moss Gold mine,” said Ken Berry, president and CEO of Northern Vertex. “In less than two years, we were successful in obtaining financing, completing construction and achieving commercial rates of production.”

As a result of the exceptional performance of the crushing plant, the operational team and the mining contractor N.A. Degerstrom, production is expected to be significantly higher, Berry explained. Guidance for gold and silver production for the Moss mine for 2019 is now 32,000 oz to 36,000 oz gold and 224,000 oz to 248,000 oz silver.
