Sylvite Four-Six is a unique regional partnership formed to prepare for significant growth, catalyzed by one of the largest private sector investments in Saskatchewan history – BHP’s $14B potash mine near Jansen, Saskatchewan. The group takes its name from sylvite – the mineral form of potash – and Treaty Four and Treaty Six, which cover parts of Saskatchewan proximate to the mine site. The name depicts the deeply collaborative nature of the partnership which is comprised of rural municipalities, Indigenous nations, cities and towns and is supported financially by both federal and provincial governments along with BHP. 

Who We Are

We are a group of communities working together to create and advocate for enhanced opportunities within the region. All communities within a 90-kilometre distance from the Jansen mine – plus the First Nations of George Gordon, Kawacatoose, Day Star, Fishing Lake, Muskowekwan, and Beardy’s and Okemasis’ Cree Nation – are eligible to join S4-6.
