This strip mining project involved stripping and stockpiling 30,000 cubic yards of topsoil and the excavation of over 400,000 cubic yards of alluvium to expose the remaining 2.7 million cubic yards of rhyolite overburden. The overburden was removed utilizing a drill and blast technique while maintaining the integrity of a 210 foot high wall. Work also included the construction and maintenance of haul roads and ramps. Equipment used for excavation consisted of Cat 631 Scrapers for alluvium removal and CAT 775 trucks being loaded with CAT 375, 385, & 390 Excavators for rhyolite removal. The project ran as a double shift, 5 days per week, being completed 1 month ahead of schedule.
