The property comprises the Rochester mine, Nevada Packard deposit and associated heap leach facilities, located in the Pershing county of Nevada. Access to the property from the town of Lovelock (25km southwest) is via a combination of paved and all weather gravel roads. There is significant potential to expand resources and reserves through ongoing exploration. In 2017, Rochester produced 51koz of gold and 4.7Moz of silver.
