• Jerritt Canyon Mine | Jerritt Canyon Gold

    All underground mines in Jerritt Canyon are less than 1000 feet in depth. Low profile 35 and 40-ton tractors are used to remove ore, which is then stacked near the mine portals for grade sampling. After sampling, ore is transported by 150-ton haul trucks to the mills, where the feed is dried and roasted.
