Designed to recover underground gold deposits which were located near an open pit mining operation, the Leeville Shafts project included the excavation and concrete lining of two separate shafts: a 22-foot-diameter, 1,900-linear-foot production shaft, and a 20-foot-diameter, 1,650-linear-foot ventilation shaft.

Both shafts were excavated using typical drill and blast techniques. Cover and contact grouting techniques also were used throughout the project in order to control the inflow of ground water. In addition to excavation work, Atkinson installed various surface facilities, performed head frame and collar installations, and set up temporary facilities and sinking plants for both shafts.
