Current Operations

York Potash



Based in North Yorkshire, within the United Kingdom, York Potash is Sirius Minerals' flagship development asset, proposing to develop a new potash mine near Whitby, North Yorkshire. Planning permission is currently being sought for the project and further details can be viewed on the York Potash website's planning pages.


The mine will be the first new potash mine in the UK for 40 years and will be a deep shaft mine of unprecedented design and world leading example within the mining industry. The Project area of interest lies between Whitby and Scarborough, extending about 16 km inland from the coast and up to 14 km off shore   Within this area lies the thickest and highest grade polyhalite Ore Reserve in the world.


The Project is targeting the production of polyhalite, a naturally occurring mineral containing four of the six macro-nutrients required for plant growth (potassium, sulphur, magnesium and calcium). Initially, the saleable products will take the form of powdered or granulated polyhalite that can be used as a directly applied fertilizer which is proven to be suitable for widespread commercial farming, including organic farming. More information about the characteristics of polyhalite and our global crop study programme can be found here. 


The York Potash Project will also involve the development of an underground mineral transport system from the mine to a proposed new materials handling facility at Wilton on Teesside. From there it will be transported via conveyor to a berth facility where it will be shipped from.


The scope of the Project is currently a 13 mtpa operation and is proposed to be constructed in two phases. The first phase is designed to provide a 6.5 mtpa operation with the ability to be expanded to 13 mtpa over a period of years. At full production the mine will bring an annual contribution to the UK GDP of over £1 billion, helping the UK’s prosperity and growth.  It will also help to reduce the country’s trade deficit, making it a truly nationally significant project.


The initial development for the Project will target multiple routes to market including production of large-scale granulated polyhalite as a direct application fertilizer and as a main source of potassium for the production of nitrogen, phosphorus and potassium fertilizers (NPK). The Project will have significant expansion capacity beyond initial development with options to produce Sulphate of Potash (SOP) from the polyhalite ore at a later stage. In addition to polyhalite, York Potash has vast quantities of Sylvite, a source of Muriate of Potash (MOP).  The immediate focus for the Project is on the development of the polyhalite resource which has the potential to be a major player in global food security issues.


The York Potash Project asset is the largest and highest grade polyhalite resource in the world, laying the foundation for Sirius to become a leading global large scale potash and multi-nutrient producer.






Polyhalite is a naturally occurring evaporite mineral comprising hydrated sulphates of potassium, calcium and magnesium, with the chemical formula K2SO4.MgSO4.2CaSO4.2H2O.


Polyhalite will be mined by Sirius Minerals and used as a unique four-in-one macro-nutrient fertilizer to provide a rich source of potassium, sulphur, magnesium and calcium. It can also be combined with other fertilizers as a feedstock to create other commonly used fertilizer blends.


Independent tests have proven it is suitable for widespread commercial farming, including organic farming and is a low carbon footprint, high nutrient content fertilizer which has excellent nutrient availability to the plant. 


The Company's production of polyhalite will help to provide a solution to the challenge of global food security as York Potash will become one of the most significant large scale suppliers of multi-nutrient fertilizers.


Technical Specifications

POLY4 is the powder and granulated product that will be produced from the York Potash Project and is a granular presentation of micronized polyhalite suitable for common agricultural fertilizer spreaders. POLY4 has been proven to be a fully soluble multi-nutrient fertilizer suitable for soil application at all commercial application rates, is pH neutral and has no negative effect on soil conductivity at commercial application rates. For more details on the characterisation tests carried out on polyhalite please click here.


Polyhalite has also been granted authorisation for use in organic systems certified by the Soil Association and the Organic Farmers and Growers.  


160 countries worldwide have organic farming systems which represents a total of 37 million hectares globally (IFOAM, 2010). Strict regulations, known as ‘standards’, define what organic farmers can and cannot do – and place a strong emphasis on the protection of wildlife and the environment.    


Balanced fertilization

Nutrients are complimentary to each other and a deficiency in any of them will limit crop growth and quality, the so-called “law of the minimum.” Balanced fertilization, particularly of the six macro-nutrients (nitrogen, phosphorus, potassium, sulphur, magnesium and calcium), is essential to obtain optimal crop yields. With most regions experiencing the challenges of multiple nutrient deficiencies, balanced fertilization will have to be at the centre of achieving sustainable growth to feed the world.


Polyhalite is a unique natural and organic mineral that contains four macro-nutrients that are known to be important for crops and soils: potassium, sulphur, magnesium, and calcium. The nutrient breakdown of pure polyhalite – K2SO4.MgSO4.2CaSO4.2H2O – is as follows: potassium: 16% as K2O; sulphur: 21% as S; magnesium: 7% as MgO; and calcium: 19% as CaO. Each of these nutrients play a vital role in the crop life cycle.
