Our Potash Expansion Program

Driven by our vision to be the world’s leading crop nutrition company, we look to lead the way toward a more productive and prosperous tomorrow – one that will benefit us all. We are committed to our mission to help the world grow the food it needs, and growth continues to be our guiding force.

In 2008, Mosaic embarked on a multi-billion dollar expansion program in Saskatchewan. Consisting of several distinct multi-year projects at each of our three Canadian mine sites – Belle Plaine, Colonsay and Esterhazy – the expansion program was designed to leverage existing facilities and infrastructure at our mines, which possess a century’s worth of potash reserves.

We anticipate our completed and in-progress expansion efforts will add nearly three million tonnes to our annual nameplate potash capacity. This further reinforces our position as one of the world’s leading potash producers.

The Esterhazy K3 Project

K3 at Esterhazy is the remaining project in Mosaic’s potash expansion. Standing 374 feet above the prairie landscape, there is no greater representation of Mosaic’s growth and investment in the future than the Esterhazy K3 production headframe and the development of the mine site below. As the current tallest structure in Saskatchewan, the production headframe will house and operate the massive hoist and skips that will bring potash to the surface from nearly a kilometer underground.

The first stage of the K3 Project was approved in 2009 as part of Mosaic’s strategy to ensure the viability of our Esterhazy Operations. In 2015, a modified project scope was approved to accelerate the second stage of K3 development.

The K3 site is expected to begin delivering tonnes in 2017 and it will serve as a satellite mine for the upgraded K2 surface facilities, which saw increases to milling and storage capacity during Esterhazy’s Stage 1 expansion efforts.

K3 will consist of two shafts, mine development and surface facilities. Sinking of the shafts began in 2013 and is expected to continue through to 2016, at which time the potash seam will be reached and mine development will begin.

As impressive as this new mine site will be, of even greater significance is the impact it will have on the long-term sustainability of the community and our ability to help farmers around the world produce the food we all need.
