SRK Consulting (SRK) recently undertook the closure design for the Gold Bar tailings facility at the Atlas
Gold Bar Mine, a defunct operation in central Nevada, USA. The tailing facility covers approximately 80
hectares (200 acres) (Figure 1) and is divided into three cells. This paper covers SRK’s approach to the
closure design engineering and to the closure implementation while meeting State reclamation requirements.
SRK’s approach to closure was guided by published papers and statics related to tailings failures, and also
internal experience with having completed numerous other closure designs and closure construction, as well
as closure and reclamation requirements for the State of Nevada. The closure design was performed in late
2005 while the implementation was undertaken in two time periods, namely during the winter of 2005/2006
and again the early summer of 2006.
