  • 1 - What is the Kronau Project?

    The Kronau Project is a proposed potash mine and Vale’s first potash project in Canada. Located in Saskatchewan, approximately 30 km southeast of Regina, the Kronau Project is 1.6 km from the Hamlet of Kronau. We estimate that the mine will produce some 3-4 million tonnes of potash per year for over 40 years while contributing significant economic benefits to the community.

  • 2 - What kind of mining is proposed for the Kronau Project?

    The Kronau Project is planned as a “solution” mine. In solution mining, wells are drilled from the surface, and water or brine is injected to dissolve the potash. The resulting brine is then pumped from the cavern to a surface processing plant, where the potash can be extracted. This type of mining minimizes surface disturbance and allows most land activities, like farming, to continue in the area.

    Once the cavern has been fully mined, which can take more than a decade, the remediation process begins. The cavern is closed so that it is safe, and the top section of the well is removed. The surface facilities are dismantled and the surface land is remediated to exactly as it was before mining began.

  • 3 - What is the Kronau Project’s timeline?

    On December 19, 2016, Vale announced the sale of fertilizer assets to Mosaic, which includes the Kronau Project.

  • 4 - How much water will the Kronau Project require?

    Vale estimates needing a maximum of 60,000 cubic metres of water per day. We aim to recycle as much water as possible and are exploring all opportunities to reduce water usage.

  • 5 - What is Vale going to do with the tailings (waste)?

    The Kronau Project tailings (waste) will be salt that remains from the solution mining process. This salt will be stored in a temporary storage area above ground, called a tailings management area.

    When the mine closes, after about a decade of mining, we will dissolve the tailings and restore them to the ground. This is the same process currently used by existing potash mines throughout Saskatchewan.

  • 6 - How can I receive Kronau Project updates?

    To receive Kronau Project updates, be sure to check this website regularly.

  • 7 - I have a concern or comment about the Kronau Project that I want to share with Vale. How can I reach Vale?

    We welcome all feedback from people in the communities where we operate. If you have comments, questions or feedback that you'd like to share, we want to hear from you! Please email or call +1 (306) 791-4510.

  • 8 - What is an environmental assessment?

    The environmental assessment is a co-ordinated and thorough review of the ecological, socio-economic and cultural aspects associated with any proposed development. The environmental assessment is led by the provincial government through the Environmental Assessment Branch of the Ministry of Environment.

  • 9 - How can I make a sponsorship request to Vale?

    Unfortunately, the Kronau Project is not in a position to provide funding for community projects at this time.

  • 10 - What is the Community Advisory Group?

    As we worked through the feasibility study, our goal was to be a good neighbour from the very beginning. To this end, we established the Community Advisory Group. The group was made up of representatives from the RM of Edenwold, Lajord, Sherwood, residents in and around Kronau, members of the provincial government, as well as local business leaders and public servants.

    The group put forward considerations and suggestions for the Kronau Project construction plans and operations. Should the Kronau Project advance, we will let you know how we put this feedback to use.
