KSM Project

KSM Project

Klohn Crippen Berger (KCB) provided engineering design of the Tailings Management Facility (TMF) for the Kerr Sulphurets Mitchell (KSM) Project. Designs were advanced first to PEA, then to PFS and then to EA and permitting levels of detail. With the EA and concurrent permits awarded in 2014 KCB continues to provide ongoing engineering support.

As part of the EA process, KCB conducted an assessment of geotechnical, water management, and engineering characteristics of 14 alternative TMF sites and the feasibility of constructing, operating, and closing of TMFs at these sites. Work was based on KCB site investigations between 2007 and 2011, as well as on assessment of feasible design options and interaction with site geohazards.

Comprehensive technical and design reports were produced for the PFS and to facilitate discussion of tailing management alternatives within the EA. These provided a transparent basis for ranking preferred sites and options as prescribed by Environment Canada Guidelines for the Assessment of Alternatives for Tailing Storage for Metal Mining Projects.

KCB provided assessment of climate and hydrological conditions as well as design of project wide water management structures for the Kerr Sulphurets Mitchell (KSM) Mine Project. Designs were advanced first to PEA, then to PFS and then to EA and permitting levels of detail. With the award of the EA and concurrent permits in 2014, KCB continues to provide ongoing engineering support.

To control mine water and establish a single collection point for water treatment KCB designed a Water Storage Facility that provides 50 Mm3 of contact water storage capacity to deal with storm water, freshet flows and glacial melt waters. Diversion tunnels and surface diversions were designed to address challenging conditions for water management such as avalanches and extreme terrain.
