An agreement signed between BHP Billiton and three First Nations is being called the first of its kind in southern Saskatchewan and for the province’s potash industry.

The international mining giant's agreement with the Kawacatoose, Day Star, and Muskowekwan First Nations outlines opportunities for employment, business and community development involving its Jansen potash project.

It also addresses the sharing of information important to environmental management practices.

BHP Billiton says the deal ensures the groups work together to maximize the benefits of the mine project currently under development at a site about 130 kilometres east of Saskatoon.

The mining company is spending $3.8 billion on the Jansen project. The project's mine shafts are expected to be complete in 2016 with surface facilities following in 2017.
