Canadian Pacific joined K+S Potash Canada (KSPC) to celebrate the opening of the Legacy Project mine on May 2.
"With our new location, we are making a huge step forward in the internationalization of our potash business", said board chairman Norbert Steiner, in a release.
The mine will have marketable product by the end of Q2 2017 and will reach a production capacity of two million metric tons of potash by the end of 2017.
Norbert Steiner, chairman of the board of management of K+S, says the Bethune mine enables the company to participate in future market growth, reduce average production costs and strengthen global competitiveness.
CP says the mine is the first of its kind built in Saskatchewan in more than 40 years, and the rail infrastructure built to serve it is the most significant engineering project undertaken by railroad since the mid-1980s.
CP said it would primarily use unit trains - those consisting of only one type of cargo - to ship the potash products to KSPC's handling and storage facility in Port Moody, B.C., and then on to overseas market.
The mine project was originally named Legacy, but officially changed its name today. It is the largest mine in the company's history.
