The Robinson Nevada copper and gold mine is a big place, but it has no room for guesswork. Just ask Production Analyst Leatham Hendrix. Located in rugged White Pine County near Ruth, Nevada, the Robinson site—operated by Robinson Nevada Mining Company, a division of QuadraFNX Mining, Ltd.—employs 510 people and runs a large mixed fleet that includes 29 haul trucks of 150- and 240-ton capacities. That’s a lot of equipment and manpower for Hendrix to keep tabs on, and small data collection errors can add up quickly to big management problems. “It’s one thing to capture data manually,” Hendrix says, “but there’s always the question of the ‘human factor.’ Somebody puts the wrong number in the wrong place and everything looks different from that point on.” To minimize those compounding errors, the Robinson site has used Cat® MineStar™ System since 2007.
