Through the development of its North Yorkshire polyhalite project, Sirius Minerals will become a world leading producer of polyhalite, a unique multi-nutrient fertilizer containing potassium, sulphur, magnesium and calcium.

The project involves the construction of Woodsmith Mine – south of Whitby, North Yorkshire – to extract polyhalite, and a tunnel system to transport it to a materials handling facility and harbour at Teesside. The polyhalite deposit is the world's largest and highest grade. 

Our polyhalite fertilizer product, POLY4, can improve yields and quality in a large range of crops to help meet the global challenges of food security and growing populations.
