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.
