Mayflower Drainage Tunnel – A Piece of the Climax Mine

Freeport McMoRan operates the Climax Mine and Mill near Leadville, Colorado. The Mayflower Tailings Facility incorporates a drainage tunnel into the design and fluid management system of this facility. SMD was awarded the contract to complete the second phase of the tunnel. The project site is located on Colorado Highway 91 between Wheeler Junction and Leadville, CO.

We began mobilization in June 2019 and work is proceeding well. Our goal is to finish up this work in late 2019 before the snow is too deep to handle. Drifting is typical drill, blast, muck, and support. The tunnel is 12’ wide x 14’ high, includes typical bolting, mesh, and shotcrete.
