Project Overview

K+S is putting its more than one hundred years of mining experience and world-class expertise to work on the Legacy Project.

The Legacy Project potash mine and production facility is the first new greenfield potash mine built in Saskatchewan in nearly forty years, located in the RM of Dufferin #190, near the communities of Bethune and Findlater.

Together with our Design and Project Management partner Amec Foster Wheeler, K+S Potash Canada (KSPC) is currently in the process of constructing the Legacy Project mine site. Commissioning is targeted for the summer of 2016, and K+S projects to reach the two-million-tonnes-mark of production capacity at the new location at the end of 2017.

The Legacy Project will mean new job opportunities for Saskatchewan workers, and new business opportunities for Saskatchewan companies supplying goods and services to this major economic development. It will also contribute to Saskatchewan’s growth through employment, tax revenues, utilities and local partnerships.

The construction of the mine will make K+S the only potash producer with production sites on two continents, extending the worldwide presence of K+S Group and increasing its average mine life.

Port and Rail

In addition to the mine site, the Legacy Project also includes Rail and Port initiatives.

K+S Potash Canada (KSPC) has partnered with Pacific Coast Terminals (PCT) for the port initiative. In spring of 2014, PCT and KSPC signed an exclusive, long-term agreement that called for the construction of a new potash handling and storage facility at PCT’s bulk handling facility located in Port Moody near Vancouver, British Columbia. Potash products arriving by rail from the Legacy mine will be stored on site and transported to vessels destined for K+S Group’s international clients. Construction for the modifications of this facility are currently underway.

To ensure a rail connection, KSPC partnered with Canadian Pacific (CP). Potash bound for port will transported by CP from the Legacy Project mine site. CP is currently in the process of constructing a 30 km Belle Plaine Spur line linking the Legacy site to existing CP track near Belle Plaine. KSPC will construct a 14 km line that links this spur to a loop at the potash mine’s loading facilities and will build about 6 km of storage track adjacent to its line. Learn more about the CP Belle Plaine Spur Project.

Community and Economic Benefits

K+S Potash Canada is committed to contributing to Saskatchewan’s economic growth, being an active part of the community and being a responsible neighbour.

Economic Growth Impacts

Some of the many economic benefits and opportunities of the Legacy Project include:

  • Increased employment, labour income, tax base and population of surrounding communities
  • New tax revenues from the project at all levels of government (local, provincial and national)
  • A construction workforce peaking at around 1,800 in 2015; approximately 300 permanent jobs when in production in 2017
  • New business opportunities for Saskatchewan companies supplying goods and services to a major industrial development

Community Engagement

Engaging and involving people who could be or are affected by the Legacy Project is an important part of our business. Since the initial phases of the Legacy Project, building meaningful relationships continues to be a focus.

Examples include:

  • The general public (e.g. local communities, communities of interest, landowners, and residents);
  • First Nations and Métis communities.

Engagement activities were initiated in the second quarter of 2008, and are expected to continue throughout the Legacy Project’s life. Engagement activities include presentations, community information sessions, group meetings, one-on-one meetings, site visits, supplier development forums and collaboration on contracts and employment with First Nations and Métis communities and individuals.

K+S takes the long view on any project, in the interest of protecting both people and the environment.

K+S Potash Canada strives to develop our projects and conduct operations according to the foundational principle that the requirements of economic success, scheduling and development must always be in balance with the prerequisites of health, safety, and the environment. We consider the full lifecycle of our projects when developing facilities, with the goal of sustainable, future oriented development, protecting local biodiversity and proactively managing health, safety and environmental outcomes for the benefit of all stakeholders and the community at large. We seek to do this by identifying and assessing potential interactions of our business with people and the environment, applying appropriate mitigation measures, and actively monitoring and managing our operations at all stages. We also strive to continually improve our processes over time.

Solution Mining

What is Solution Mining?

Solution mining is the process of mining underground water-soluble minerals by dissolving the minerals with water. The mineral-rich solution (called brine) is then extracted from the ground and the minerals are recovered from it.

For each cavern, two boreholes are directionally-drilled from a pad at the surface so that the wells are spaced about 80m apart at a depth of 1,500m. For the development process, a casing is inserted into each well to enable circulation of water and dissolve minerals first as a sump and finally connect the wells into a single cavern.

At this point, the production process can begin. Hot water is continuously pumped down one well, where it continues to dissolve the minerals into sodium chloride and potassium chloride-rich brine, which is pushed up the second well to the surface.

Once on the surface, the brine is processed at our facility. Using the differences in solubility for sodium and potassium chloride, the brine is concentrated and salt and potash subsequently crystallized through evaporation and vacuum cooling crystallization. The final products are finished in the dry plant, before they go to storage and train loading. As the solution mining process is water-and-energy-intensive, great efforts have been taken to conserve and re-use as much of the natural resources as possible.
