BHP Billiton has submitted an environmental impact statement (EIS) for its Jansen potash project in Saskatchewan, Canada, to the Saskatchewan Ministry of Environment.

The company prepared the EIS in compliance with regulatory requirements that assess the potential effects of the Jansen project.

BHP Billiton diamonds and specialty products president Graham Kerr said Jansen is a “world-class” ore body and the project fits the firm’s strategy of owning and operating large, long-life, low-cost assets.

According to BHP, drilling has begun at Jansen in preparation for the ground-freezing process, which is required to sink the production and service shafts.

The Jansen project, located 140km east of Saskatoon, is expected to produce approximately 8Mtpa of potash at full capacity, potentially making it the world’s largest potash mine, the firm claimed.
