Big picture - Why invest in Sirius Minerals PLC

Sirius Minerals PLC Snapshot


The Company aims to become one of the world’s largest producers of multi-nutrient fertilizers, with the central objective of unlocking value for customers and shareholders alike. Our approach to achieve this can be best described as one of disruptive innovation and is based around a simple strategy.

DISRUPTIVE MARKET PENETRATION STRATEGY: POLY4 has been consistently proven to increase crop yield and quality and will be made widely available at competitive pricing to comparable products.

LARGE-SCALE PRODUCTION CAPACITY: the Project will have an initial production capacity of 10 Mtpa, with the foundations for 20 Mtpa.

COST EFFECTIVE: our simple production infrastructure will ensure that operating costs are among the lowest in the industry.

LONG-LIFE: our polyhalite deposit is the world's largest and represents an asset in excess of 100 years.



Our values are central to the way we think and behave and are all of equal importance. Our objectives may evolve through each phase of the project, but our values will always remain at the heart of what we do.

SAFETY: Zero Harm everywhere, every time

BELIEF: Uncompromising belief and determination in our achieving our vision

RESPONSIBILITY: Accountability for our actions and acting with integrity in our work

OWNERSHIP: It's our Company and our money

URGENCY: Finding innovative, cost effective and safer ways to do things better

TEAM: Working together to reach our collective goals


The mine, located south of Whitby in North Yorkshire, will have an initial production capacity of 10 million tonnes per annum (Mtpa) and full production of 20 Mtpa.

From the outset the Project has been designed to ensure that it is sensitive to the local landscape. Surface buildings will be limited to a minimum and screened by the existing woodland, together with new landscaping which blends in with the surrounding area.

All mined polyhalite will be transported underground to the materials handling facility on the low impact mineral transport system (MTS), incorporating a high-capacity conveyor belt system in a 23 mile tunnel, which is 4.1m diameter and capable of transporting 20 Mtpa. The technology involved is well understood and widely used in underground mines around the world.

Along the MTS route there will be an intermediate shaft located at Lockwood Beck, which will be utilised to support the construction of the tunnel and used for ventilation and occasional maintenance access during operations. Planning permission has also been granted for two further intermediate shafts at Lady Cross Plantation and Tocketts Lythe.

Located in Teesside at Wilton International, the materials handling facility (MHF) will consist of the plant and equipment necessary to granulate the polyhalite and create the final product.

The mined ore will be received from the MTS tunnel conveyor into a surge bin and then crushed and milled before being taken to the screening facility. Oversized ore will be screened out and returned to the crusher, whilst the remaining ore is conveyed to the granulation area where it is converted into pellets and dried before being taken to the product storage building.

The finished product will be transported from the MHF along covered, elevated conveyor bridges to the new harbour facilities ready for export. At full production this will include two berths suitable for handling high capacity Panamax ships and the required ship loading equipment.

Planning approval for the MHF and an application for the harbour facilities Development Consent Order have both been granted.

The Deposit


Our area of interest contains the largest, highest grade resource of polyhalite to be found anywhere in the world.

The deposit was formed in the late Permian period, around 260 million years ago, in the southern North Sea basin. What was then the Zechstein Sea periodically evaporated, leaving behind a sequence of mineral deposits including the shelf and basin seams of polyhalite.

Between July 2011 and August 2013, over 16,000m of exploratory boreholes were drilled from the surface to test the extent and grade of the polyhalite deposit. From the boreholes, 4,200m of core was successfully recovered along with detailed downhole wireline logging data.

Results confirmed that our area of interest contains a polyhalite resource of 2.66 billion metric tonnes, as defined according to the internationally recognised JORC code. This is just 7% of the Project area of interest and provides an asset excess of 100 years. Within the resource area, there is a JORC compliant Probable Mineral Reserve of 280 million tonnes of polyhalite.

Polyhalite - POLY4 EXPLAINED

Polyhalite is an evaporite mineral comprising a natural combination of four of the six macro-nutrients that are essential to plant growth – potassium (14% K2O) sulphur (19% S), magnesium (6% MgO) and calcium (17% CaO) – with the chemical formula K2SO4.MgSO4.2CaSO4.2H2O. While polyhalite deposits are known to occur elsewhere, none have the mineral quality or material extent of our defined North Yorkshire resource, which is the world's largest and highest grade.

POLY4 is the trademark name of our polyhalite products. It delivers four essential macro-nutrients and many vital micro-nutrients, in one simple and efficient fertilizer product. Our high quality product is available in granulated, powdered or chipped form to meet the needs of our customers, taking into account their crop needs, blending requirements, application method and soil conditions.
